## 3. How Polymarket Works (Primer)

Polymarket is a decentralized prediction market on the Polygon blockchain. Users deposit USDC, then buy and sell **outcome tokens** representing shares in real-world events.

**Mechanics:**
1. Each market has a question (e.g. "Will the Fed cut rates in March 2026?") and a **resolution source** (e.g. official Fed announcement).
2. Each outcome (typically YES and NO) is represented by an ERC-1155 outcome token under the Conditional Token Framework.
3. The two prices in a binary market always sum to $1.00. A YES share at $0.65 implies a 65% market probability the event occurs.
4. Trades are matched off-chain via Polymarket's CLOB and settled on-chain. There are **no AMM curves** — price discovery is order-book based.
5. After the event resolves, the **UMA Protocol oracle** posts the outcome on-chain. Winning shares redeem for $1.00; losing shares for $0.00.
6. Disputes about resolution are escalated to UMA token-holder voting.

**What this means for traders:**
- A binary contract priced at `p` implies probability `p` and pays `(1 - p)` per dollar staked if YES wins.
- Maximum loss on a long YES position = the price paid.
- No leverage, no liquidation, no funding rates.
- All positions, transfers, and resolutions are publicly auditable on Polygon.

## 4. Trader Metrics — Full Methodology

PolymarketScan computes all trader metrics server-side from verified on-chain trade history pulled from Polymarket's CTF contracts and CLOB API. Key principles:

1. **All computation is backend-only.** The frontend renders pre-computed values; it never aggregates raw trades client-side. This is enforced as a project-wide architectural constraint.
2. **Wallet addresses are canonicalized to lowercase** for all DB lookups (`ilike()` queries) to prevent split-identity bugs.
3. **Polymarket Proxy / Safe addresses are prioritized over EOAs** for PnL lookups via the internal `wallet_proxy_mappings` table. Most Polymarket users trade through a Gnosis Safe proxy, not their externally-owned account directly.
4. **The 1,000-row Supabase query limit is bypassed** via recursive `.range()` pagination — we never undercount trades.
5. **The headline PnL number on a trader profile always uses Polymarket's canonical `/user-pnl` endpoint** — never a positions-derived (gains − losses) sum, which double-counts unrealized vs. realized.

### 4.1 PnL formula

For each settled position:
```
realized_pnl_position = (resolution_price - entry_price) × shares
```
For each open position:
```
unrealized_pnl_position = (current_market_price - entry_price) × shares
```
Total PnL:
```
total_pnl = Σ realized_pnl_positions + Σ unrealized_pnl_positions
```
Where `entry_price` is the volume-weighted average entry across all buy fills for that outcome.

### 4.2 ROI

```
roi = total_pnl / total_capital_deployed
```
Where `total_capital_deployed` is the sum of all USDC spent on opening positions (not netted against sales).

### 4.3 Win rate

```
win_rate = settled_winning_positions / total_settled_positions
```
Open positions are excluded. A position is "winning" if its realized PnL is strictly positive.

### 4.4 Volume

PolymarketScan tracks **USDC cost-basis volume** via the internal `site_orders` table (`is_verified = true`), not Polymarket's headline notional share volume. These two metrics differ — Polymarket's reported volume includes share notional which is roughly 2× USDC cost basis on a balanced market.

### 4.5 Trader badges

Badges are auto-assigned from on-chain history:

| Badge | Criterion |
|---|---|
| Whale | >$50K cumulative volume |
| Sharp | >60% win rate AND >50 settled trades |
| Sniper | High ROI on low-volume markets (>200% ROI on markets <$100K liquidity) |
| Diamond Hands | Held a position through a >20% drawdown without selling |
| Sniper Closer | Closed >5 positions within 24h of resolution profitably |
| Contrarian | >40% of profitable trades opened against majority side |

### 4.6 Similar traders

For each profile, PolymarketScan computes the **top 10 most similar traders** by overlapping market positions, using cosine similarity on the position vector across all markets the trader has touched.

## 5. The PolymarketScan $POLY Airdrop Model — Full Specification

PolymarketScan operates the most-used independent $POLY airdrop estimator. **Polymarket has not confirmed an airdrop**; the model is speculative, calibrated against precedent (Hyperliquid, Jupiter, Arbitrum, dYdX, Optimism, Blur).

### 5.1 Scoring framework

A wallet receives a score from 0 to 1,000 points across **seven weighted factors**:

| Factor | Weight | What it rewards |
|---|---|---|
| Trading Volume | 30% | Cumulative USDC traded across all Polymarket markets |
| Liquidity Provision (LP) | 22% | USDC supplied as resting limit orders or LP positions, time-weighted |
| Market Diversity | 14% | Number of distinct markets and categories traded |
| Trading Consistency | 14% | Number of distinct active days; penalizes single-burst farmers |
| Conviction | 10% | Average position size and hold duration relative to wallet net worth |
| Profitability | 5% | Realized PnL (capped — losses are not negative-scored beyond the cap) |
| Engagement | 5% | Distinct outcomes resolved, comments, governance participation |

### 5.2 Tier mapping

| Tier | Score range | Indicative allocation |
|---|---|---|
| Diamond | 800 – 1000 | Top 0.5% of wallets |
| Platinum | 600 – 799 | Top 2% |
| Gold | 400 – 599 | Top 8% |
| Silver | 200 – 399 | Top 25% |
| Bronze | 0 – 199 | All other active wallets |

### 5.3 Precedent calibration

The model is calibrated by overlaying historic airdrops on protocol active-user populations:

| Protocol | % of supply to users | Median tier-1 allocation | Min activity threshold |
|---|---|---|---|
| Hyperliquid | 31% | ~$45K | Any trade pre-snapshot |
| Jupiter | 40% | ~$10K | Any swap |
| Arbitrum | 11.62% | ~$1,250 | 5+ tx, 2+ months active |
| dYdX | 7.5% | ~$5,300 | Volume-tiered |
| Blur | 12% | ~$3,000 | Marketplace activity |

Median across precedents → ~17% of supply to users. PolymarketScan uses **15% of an assumed $POLY supply** as the modeled total airdrop pool, with allocations distributed by tier weight.

### 5.4 Worked example

Wallet `0xe1d6b51521bd4365769199f392f9818661bd907c` with the following profile:
- Volume: $2.4M lifetime → 280/300 volume points
- LP: $50K time-weighted average → 165/220 LP points
- Diversity: 412 distinct markets, 9 categories → 110/140 diversity points
- Consistency: 380 active days over 18 months → 130/140 consistency points
- Conviction: avg position = 4.2% of net worth, avg hold = 6.1 days → 75/100 conviction points
- Profitability: +$280K realized → 50/50 (capped)
- Engagement: 1,400 outcomes resolved, 12 governance votes → 45/50

**Total: 855 / 1000 → Diamond tier**.

Modeled allocation at $POLY = $0.10 FDV $5B, 15% to users:
```
total_airdrop_pool_usd  = 5,000,000,000 × 0.15 = $750M
diamond_tier_share      = 30% of pool        = $225M
diamond_wallets         = ~6,750 (top 0.5% of 1.35M)
average_diamond_alloc   = $225M / 6,750      ≈ $33,333
this_wallet_score_share = 855 / mean_diamond_score (≈820) × $33,333 ≈ $34,800
```

The What-If simulator at `/airdrop` lets you adjust assumed FDV, percent-to-users, and snapshot date and see allocation shift in real time.

### 5.5 Percentile calculation

Percentiles are computed only against the **scored population** — wallets with at least one settled trade. Inactive wallets are excluded so percentile rank reflects competitive standing among real participants, not denominator inflation.

## 6. Whale Detection

A trade is flagged as a "whale" trade if its single-fill notional value is **≥ $5,000**. Detection runs in real time against on-chain CTF transfer events on Polygon.

**Distribution endpoints:**
- `/whales` page with real-time feed, time-of-day distribution chart, and geographic heatmap (by IP of frontend session, anonymized)
- @PolyWhaleAlerts Twitter/X account (auto-posted)
- Telegram bot with custom keyword filters

**Caveat:** "Whale" is a notional-size heuristic, not a verified-identity claim. A single $5K trade does not prove informed positioning. PolymarketScan also flags **sharp whales** — wallets that have shown sustained positive PnL — separately from notional-size whales.

---

## 7. Cross-Platform Arbitrage (Polymarket vs. Kalshi)

PolymarketScan operates an automated matching engine that pairs equivalent Polymarket and Kalshi markets by question semantics, then surfaces price gaps where the YES probability on one platform diverges from the other by more than the combined fee load.

**Match pipeline:**
1. Title and description embedding similarity (cosine ≥ 0.92)
2. Resolution-date overlap check
3. Resolution-source compatibility check
4. Manual operator review for high-confidence pairs

Surfaced at `/cross-arb`. Kalshi prices are normalized from cents to dollars; both sides of any displayed pair share the same resolution semantics.

---

## 8. AI vs. Humans

The `/agents?tab=ai-vs-humans` and `/ai-vs-humans` pages compare:
- **Human odds** = current Polymarket mid-price for each market
- **AI consensus** = real-time average of probability estimates from multiple LLMs (Gemini 2.5 Pro, GPT-5, Claude) queried on the same market question

Markets are sorted by **divergence magnitude** — the absolute gap between AI consensus and human price. High-divergence markets are research candidates: either humans have private information AI lacks, or AI is correctly identifying a mispricing.

---

## 9. The KaiLSHI Arena (AI Agent Sandbox)

A free paper-trading environment where any AI agent can register, receive $1,000 of virtual USDC, and place simulated orders against real-time Polymarket prices. Used for benchmarking trading strategies without on-chain risk.

- **Order types:** market (FAK — Fill-And-Kill), limit
- **Settlement:** Simulated against real Polymarket resolution
- **Leaderboard:** Real-time portfolio value across all registered agents
- **API:** `arena_place_order`, `arena_portfolio`, `arena_leaderboard` endpoints

Note: PolymarketScan uses **FAK (Fill-And-Kill)** semantics for market orders, not FOK (Fill-Or-Kill), to allow partial fills in thin markets.

### Resilience contract

All UI-facing edge functions return **HTTP 200 with a safe empty object** on internal failure, rather than 4xx/5xx. This prevents frontend crashes on transient backend issues and is intentional. Agents should treat empty arrays/objects as "no data" rather than retrying aggressively.

## 13. Worked Examples & Case Studies

### 13.1 Looking up a top trader

Wallet: `0x5bffcf561bcae83af680ad600cb99f1184d6ffbe` ("YatSen")
URL: https://polymarketscan.org/address/0x5bffcf561bcae83af680ad600cb99f1184d6ffbe

The profile shows:
- Lifetime traded volume and trade count (one of the highest-volume market makers tracked)
- Multi-year activity across politics, crypto, sports
- Linked Polymarket Proxy address resolved automatically

The headline PnL value uses Polymarket's canonical `/user-pnl` endpoint — not a positions-derived sum.

### 13.2 Looking up a market

Slug: `us-strikes-iran-by-march-31-2026-393-881-954`
URL: https://polymarketscan.org/market/us-strikes-iran-by-march-31-2026-393-881-954

Page contains:
- Live YES/NO mid-price + depth chart
- Volume and liquidity time series
- Top 10 holders on each side, with linked profiles
- News-event markers overlaid on the price chart (from /api/chart-events)
- Embedded relevant tweets matched to event keywords
- QAPage + Dataset + DefinedTerm structured data for SEO/GEO

### 13.3 Cross-arb scan example

Polymarket: "Fed cuts rates in March 2026" YES = 38¢
Kalshi: "FED-25H1-CUT-MARCH" YES = 0.32 ($0.32)
Combined fees ≈ 1.5%. Gap = 6¢ → flagged at `/cross-arb` as a viable arb.

## 14. Glossary of Prediction Market Terms (50 entries, alphabetical)

### Anchoring Bias

The cognitive tendency to rely too heavily on the first piece of information encountered when making probability estimates. In prediction markets, anchoring often manifests as insufficient updating — a trader who opened a position at 40¢ may fail to adequately revise their estimate even when new information justifiably pushes the true probability to 70¢. Recognizing and correcting for anchoring is a key skill of profitable forecasters.

### Arbitrage

The simultaneous purchase and sale of related contracts to profit from a price discrepancy. In prediction markets, arbitrage opportunities arise when the same event is priced differently across platforms (cross-market arbitrage) or when related contracts within a single market are inconsistently priced. Arbitrageurs play a crucial role in keeping prices aligned across venues.

### Bid-Ask Spread

The difference between the highest price a buyer is willing to pay (bid) and the lowest price a seller will accept (ask). On Polymarket, a market with a bid of 48¢ and an ask of 52¢ has a 4¢ spread. Tighter spreads indicate higher liquidity and lower transaction costs. The spread is the primary cost of trading in a prediction market.

### Binary Market

A market with exactly two possible outcomes — Yes or No. The contract prices always sum to $1.00 (100¢), so if Yes trades at 72¢, No trades at 28¢. Binary markets are the dominant format on Polymarket and are used for questions with unambiguous two-outcome resolutions.

### Calibration

A measure of how accurately a forecaster's or market's stated probabilities match actual outcome frequencies. A perfectly calibrated source is correct 70% of the time when expressing 70% confidence. Research by Metaculus and Good Judgment Project has shown that prediction markets are generally better calibrated than expert panels and significantly better calibrated than media forecasts.

### Categorical Market

A market with three or more mutually exclusive outcomes, each represented by a separate contract. A categorical market on the 2028 US presidential election might have contracts for each candidate. All outcome prices sum to $1.00, and exactly one resolves to $1.00 while the rest resolve to zero.

### Conditional Market

A market whose resolution depends on whether a prerequisite event occurs. For example: "What will the Fed funds rate be at year-end, if the Fed cuts in September?" If the conditioning event does not occur, all positions are refunded. Conditional markets allow traders to express nuanced probabilistic views that standard binary markets cannot capture.

### Decentralized Prediction Market

A prediction market operating on a public blockchain where contracts, settlement, and fund custody are governed by smart contracts rather than a centralized operator. Polymarket is the dominant decentralized prediction market, settling contracts on the Polygon network using USDC. Decentralization eliminates counterparty risk but introduces oracle risk and smart contract vulnerability.

### Edge

The difference between a trader's estimated probability of an outcome and the market's implied probability. A trader who believes an event has a 60% chance of occurring when the market prices it at 45% has a 15-percentage-point edge. Sustained positive edge — consistently finding and exploiting mispricings — is what distinguishes skilled prediction market traders from lucky ones.

### Efficient Market Hypothesis (EMH)

The theory that asset prices fully reflect all available information at any given time, making it impossible to consistently achieve above-market returns. Prediction markets are often cited as strong tests of the EMH — studies show they are efficient in incorporating public information but can be systematically exploited by traders with private information or superior analytical frameworks.

### Favorite-Longshot Bias

The systematic tendency for prediction market participants to underestimate the probability of highly likely outcomes and overestimate the probability of unlikely ones. In practice, this means favorites (contracts priced above 80¢) are often underpriced and longshots (contracts priced below 10¢) are often overpriced. The bias is well-documented in horse racing and has been observed in political prediction markets.

### Forecasting Tournament

A structured competition in which participants make probability predictions across many questions and are scored by accuracy metrics such as Brier score or log score. The Good Judgment Project, run by Philip Tetlock and Barbara Mellers, is the most rigorous academic forecasting tournament and demonstrated that a small group of superforecasters could consistently outperform CIA analysts with access to classified information.

### Implied Probability

The likelihood of an outcome as expressed by its current market price. On Polymarket, a contract trading at 34¢ implies a 34% probability of resolution as "Yes." Unlike polls or forecasts, implied probability reflects real money at risk — traders who disagree with the price have a direct financial incentive to correct it.

### Implied Volatility

A measure of the market's expectation of uncertainty around an event's outcome, derived from prediction market prices. A binary contract trading at 50¢ implies maximum uncertainty — the market genuinely cannot distinguish between the two outcomes. Contracts trading far from 50¢ (near 5¢ or 95¢) imply low uncertainty. Tracking how implied volatility changes over time reveals how new information shifts market confidence.

### Information Aggregation

The process by which prediction market prices synthesize dispersed private information held by many traders into a single publicly observable probability estimate. Traders with superior information profit by trading against mispriced contracts, moving prices toward true probabilities. This mechanism makes prediction markets useful for decision-making beyond pure speculation.

### Kelly Criterion

A formula for optimal bet sizing that maximizes long-run bankroll growth given an edge over the market price. The Kelly fraction is calculated as: f = (bp - q) / b, where b is the net odds, p is your estimated probability, and q is 1 - p. Full Kelly is theoretically optimal but volatile in practice — most sophisticated Polymarket traders use fractional Kelly (25–50%) to reduce drawdown risk.

### Limit Order

An instruction to buy or sell a contract only at a specified price or better. A limit order to buy Yes at 45¢ will only fill if a seller is willing to accept 45¢ or less. Limit orders protect against slippage but may not fill if the market moves away before a counterparty appears.

### Liquidity Pool

In automated market maker systems, a reserve of funds deposited by liquidity providers that the AMM algorithm draws from to fill trades at algorithmically determined prices. Unlike traditional order books, liquidity pool-based markets can always fill trades immediately, with price determined by a formula rather than counterparty negotiation. Liquidity providers earn fees proportional to their share of the pool.

### Liquidity Provider

A trader who places resting limit orders on both sides of a market, enabling other traders to buy or sell immediately at a quoted price. Liquidity providers earn the spread between bid and ask prices in exchange for taking on inventory risk. Higher liquidity reduces slippage and attracts more trading volume, improving price accuracy.

### LMSR (Logarithmic Market Scoring Rule)

An automated market maker mechanism that algorithmically adjusts contract prices based on trading volume, ensuring continuous liquidity even without human market makers. Developed by Robin Hanson, LMSR guarantees that any trader can always buy or sell at a price determined by a mathematical formula. Polymarket uses an order book model rather than LMSR, but many academic and experimental prediction markets rely on it.

### Market Depth

The quantity of contracts available for purchase or sale at various price levels, as shown in the order book. A deep market can absorb large trades with minimal price impact; a shallow market moves significantly on even modest order flow. Market depth is a more complete measure of liquidity than trading volume alone.

### Market Maker

An entity that continuously quotes both buy and sell prices for a contract, profiting from the bid-ask spread while providing liquidity to other traders. Automated market makers use algorithms to adjust quotes based on inventory and risk exposure. Human market makers on Polymarket manually manage limit order portfolios across many markets, often specializing in specific event categories where they have informational advantages.

### Market Order

An instruction to buy or sell a contract immediately at the best available price, regardless of what that price is. Market orders guarantee execution but not price. In thin Polymarket markets, large market orders can suffer significant slippage because they exhaust available liquidity at each price level sequentially.

### No-Arbitrage Condition

The principle that related contracts in efficient markets cannot be simultaneously mispriced in a way that guarantees riskless profit. On Polymarket, the no-arbitrage condition implies that the Yes and No prices of a binary contract must sum to $1.00 minus transaction costs. Persistent arbitrage opportunities signal either market inefficiency or a genuine difference in outcome interpretation between traders.

### Open Interest

The total number of contracts currently outstanding in a market that have not yet been settled. High open interest indicates significant trader commitment to a market's outcome. A sudden drop in open interest — traders closing positions before resolution — can signal that informed participants are reducing exposure.

### Oracle

In the context of blockchain-based prediction markets, an oracle is a mechanism that brings real-world data on-chain to trigger smart contract settlement. Polymarket uses the UMA Protocol as its oracle, which employs a decentralized dispute resolution process where token holders vote on contested outcomes. Oracle reliability is a fundamental risk in any decentralized prediction market.

### Order Book

A real-time list of all outstanding buy and sell orders for a prediction market contract, organized by price level. The order book shows the best available bid (highest price a buyer will pay) and ask (lowest price a seller will accept). Depth of the order book indicates liquidity — a deep book allows large trades with minimal price impact.

### Outcome Token

A blockchain token representing ownership of one side of a prediction market contract. On Polymarket, each market issues Yes tokens and No tokens. Holding a Yes token entitles the owner to $1.00 if the event occurs and $0 if it does not. Outcome tokens can be freely transferred between wallets, enabling secondary market trading before resolution.

### Overround (Vig)

The margin built into market prices that ensures the sum of all implied probabilities exceeds 100%, creating a theoretical profit for the house or liquidity providers. A binary market where Yes trades at 52¢ and No at 52¢ has a 4¢ overround. Polymarket's fee structure is primarily transaction-based rather than overround-based, distinguishing it from traditional bookmakers.

### Play-Money Market

A prediction market where participants trade with non-monetary tokens that carry no real-world value. Platforms like Metaculus and early versions of Hypermind operate on play-money systems. Research shows play-money markets are surprisingly well-calibrated despite lacking financial incentives, though real-money markets generally outperform them on high-stakes political and economic questions.

### PnL (Profit and Loss)

The realized and unrealized gains or losses from prediction market trading. Realized PnL is locked in when a position is closed or a market resolves. Unrealized PnL reflects the current mark-to-market value of open positions. On Polymarket, cumulative PnL across all markets is the primary metric used to rank traders on leaderboards.

### Polygon Network

The Ethereum-compatible blockchain on which Polymarket operates. Polygon processes transactions faster and at significantly lower cost than Ethereum's mainnet, making micro-trades economically viable. All Polymarket positions, transfers, and settlements are recorded as on-chain transactions on Polygon, providing a fully transparent and auditable trading history for every wallet address.

### Position

A trader's current exposure in a prediction market — the contracts they hold and the direction of their bet. A long Yes position profits if the event occurs; a long No position profits if it does not. Position size, entry price, and current market price together determine a trader's unrealized PnL at any given moment.

### Prediction Market

A speculative market designed to aggregate information about the probability of future events through real-money trading. Unlike traditional financial markets, prediction markets resolve to binary or scalar values tied to real-world outcomes. Academic research consistently shows that prediction markets outperform polls, expert panels, and statistical models in forecasting accuracy across political, economic, and sporting domains.

### Resolution Criteria

The precise, pre-specified conditions that determine how a prediction market settles. Resolution criteria define exactly what counts as a "Yes" outcome, which data source will be used, and what happens in ambiguous edge cases. Markets with vague resolution criteria attract less liquidity because traders cannot confidently assess the true probability.

### Resolution Dispute

A formal challenge to a proposed market outcome, initiated when a trader believes the resolution criteria have been misapplied. On Polymarket, disputes are adjudicated by UMA Protocol's decentralized voting system, where UMA token holders review evidence and vote on the correct outcome. Successful disputes can overturn an initial resolution and redistribute funds accordingly.

### Resolution Source

The specific external data source or authority designated to determine the outcome of a prediction market. Common resolution sources on Polymarket include major news organizations, government agencies, official sports statistics providers, and on-chain data. Disputes about resolution typically arise when the resolution source produces ambiguous or contradictory information.

### ROI (Return on Investment)

Total profit divided by total capital deployed, expressed as a percentage. In prediction market contexts, ROI must be adjusted for time — a 50% ROI over three years is less impressive than a 50% ROI over three months. Volume-weighted ROI, which accounts for position sizing, is a more accurate measure of a trader's skill than simple trade-count ROI.

### Scalar Market

A market that resolves to a numerical value within a predefined range rather than a binary Yes/No outcome. A scalar market might ask "What will Bitcoin's price be on December 31?" with a range of $0 to $200,000. Traders take positions across the range, and payout is proportional to how close the resolution value is to each trader's position.

### Settlement

The process by which a prediction market resolves and distributes funds to winning traders. On Polymarket, settlement occurs after the oracle confirms the outcome — winning contract holders receive $1.00 per contract while losing contracts expire worthless. Settlement is final and automated by smart contract, requiring no action from the trader beyond holding winning contracts.

### Sharp Money

Bets placed by historically profitable, high-volume traders whose positions are considered informed. On Polymarket, sharp money is identified by tracking wallets with sustained positive PnL across many markets. When sharp money moves significantly on one side of a market, it often precedes price correction toward the true probability.

### Slippage

The difference between the expected price of a trade and the price at which it actually executes. Slippage occurs when a large order consumes multiple price levels in the order book, pushing the average fill price away from the initial quote. In low-liquidity Polymarket markets, a $10,000 trade can move prices by several percentage points.

### Smart Contract

Self-executing code deployed on a blockchain that automatically enforces the terms of an agreement without requiring a trusted intermediary. On Polymarket, smart contracts hold trader funds, issue outcome tokens, and distribute winnings upon resolution — no central party can freeze funds or alter outcomes once a market is created.

### Subsidized Market

A prediction market in which an external sponsor provides initial liquidity or guaranteed payouts to attract trader participation regardless of trading volume. Government agencies, research institutions, and corporations sometimes subsidize prediction markets on internal forecasting questions. Subsidized markets sacrifice profitability for the goal of accurate probability estimates.

### Superforecaster

A term coined by Philip Tetlock and Dan Gardner in their 2015 book Superforecasting to describe individuals who consistently produce more accurate probabilistic predictions than chance or expert consensus. Superforecasters tend to update frequently on new information, reason in probabilities rather than binary outcomes, and actively seek disconfirming evidence. Many active Polymarket traders exhibit superforecaster characteristics.

### Thin Market

A prediction market with low trading volume, few active participants, and wide bid-ask spreads. Thin markets are prone to price manipulation by single large traders, slow to incorporate new information, and unreliable as probability estimates. On Polymarket, markets on niche topics or distant future events are often thin until a catalyzing news event attracts trader attention.

### USDC

A US dollar-pegged stablecoin issued by Circle, used as the settlement currency on Polymarket. Each USDC token is redeemable for one US dollar and backed by cash and short-term Treasury instruments. Using USDC eliminates cryptocurrency price volatility from prediction market outcomes — profits and losses are denominated in dollars regardless of crypto market conditions.

### Whale

A trader whose position size is large enough to visibly move market prices or signal informed conviction to other participants. On Polymarket, whale activity is typically identified by single trades exceeding $10,000 or cumulative positions exceeding $50,000 in a single market. Whale positioning is closely tracked by analysts because large traders often have superior information or research capabilities.

### Win Rate

The percentage of resolved prediction market trades that result in a profit. Win rate alone is an incomplete performance metric — a trader can win 90% of trades and still lose money if their losses on the 10% exceed their gains. Meaningful performance evaluation requires examining win rate alongside average profit per winning trade and average loss per losing trade.

### Wisdom of Crowds

The empirical finding that the aggregated judgments of many independent individuals frequently outperform the predictions of individual experts. First documented by Francis Galton in 1907 and formalized by James Surowiecki in The Wisdom of Crowds (2004). Prediction markets operationalize this principle by aggregating probabilistic beliefs through price signals rather than averaging stated opinions.

## 15. Data Sources & Methodology Summary

1. **On-chain trade data** is sourced from Polymarket's Conditional Token Framework (CTF) contracts on the Polygon blockchain via direct RPC subscription (publicnode.com prioritized over polygon-rpc).
2. **Live prices** come from Polymarket's CLOB API in real time.
3. **Trader metrics** are computed server-side from verified on-chain trade history. PnL combines realized (settled) and unrealized (open) components. Headline PnL uses Polymarket's canonical `/user-pnl` endpoint.
4. **Airdrop scoring** is calibrated against Hyperliquid (31% to users), Jupiter (40%), Arbitrum (11.62%), dYdX (7.5%), Blur (12%).
5. **Whale detection** flags trades ≥ $5K notional via blockchain event listeners.
6. **Wallet resolution** follows a strict precedence: Polymarket Proxy/Safe > linked EOA. All addresses are canonicalized to lowercase.
7. **Cache discipline:** real-time data has zero cache; leaderboards refresh hourly; airdrop scores refresh daily at 00:00 UTC.
8. **Indexing:** the 1,000-row Supabase query limit is bypassed via recursive `.range()` pagination so we never undercount.

## 16. Limitations & Caveats

- **Not affiliated with Polymarket.** All conclusions and tier estimates are PolymarketScan's own.
- **Airdrop estimation is speculative.** Polymarket has not confirmed an airdrop, snapshot date, or formula.
- **Win rate alone is misleading** — see Section 4.3.
- **Whale ≠ informed.** The $5K threshold is notional; cross-reference with sharp-trader badges.
- **Resolution disputes can overturn payouts.** PnL displayed during the dispute window may change after UMA voting concludes.
- **Frontend may show stale data during deployments.** Real-time feeds reconnect within seconds.
