A prediction market where people trade on yes/no questions with real money. The YES price is the market's implied probability — 0.72 = 72% chance of YES. All prices should obey basic math: in a binary market, YES + NO = 1.00. In a multi-outcome event, all YES prices must sum to 1.00.

Polyscanner scans hundreds of live Polymarket markets in real time looking for mechanical price inconsistencies — places where the math breaks down and a guaranteed or near-guaranteed profit exists. No models, no predictions, just arithmetic.

⚡ YES+NO Arb — In any binary market, YES + NO must equal exactly 1.00 at resolution. If they currently sum to less than 1.00 (e.g. 0.94), you can buy both sides right now and lock in the difference as guaranteed profit regardless of outcome. Only shows edges above 3% to clear Polymarket's fee.

🎯 Field Arb — Multi-outcome events (elections, F1, tournaments) where exactly one outcome wins. All YES prices must sum to 1.00. If they sum to less (e.g. 0.88), every outcome is underpriced relative to its fair share — buy the most underpriced YES tokens for a guaranteed pool edge. Only shows events with >3% total edge.

🔗 Correlated — Markets within the same event whose prices are logically inconsistent. Finds pairs of outcomes in the same event where the combined YES prices diverge significantly from 1.00, signalling one or both sides are mispriced. Requires at least 8% divergence.

🔥 Expiring — Active markets resolving within 30 days still priced between 20¢ and 80¢. The closer to expiry and the closer to 50/50, the higher the uncertainty score. If you have information the market doesn't, these offer the best leverage.

📉 Sell Arb — The mirror of YES+NO Arb. If YES + NO sum to more than 1.00, sell both sides: buy NO on the YES market and YES on the NO market. You collect more than $1 upfront and only ever pay out $1 at resolution. Only shows edges above 3%.

📉 Field Sell — Mirror of Field Arb. When all YES prices in a multi-outcome event sum to more than 1.00, buy NO on every outcome. At least one NO is guaranteed to pay out $1, and you collected more than $1 total. Only shows events with >3% total edge.

⏳ Post-Expiry — Markets that passed their end date but haven't been officially resolved yet. If the real-world outcome is already public knowledge, the remaining price gap is free money. Always verify the outcome yourself before acting — resolution can be delayed for legitimate reasons.

All scanners filter out edges below 3% for binary markets and 3% for field markets. This is intentional: Polymarket charges a fee on winnings, and sub-3% "edges" are typically noise or will be consumed by the spread. Only edges that meaningfully clear the fee are shown.

Not financial advice. Prediction markets carry real risk — resolution can be disputed, liquidity can be thin, and prices can move before your order fills. Only trade what you can afford to lose. Always verify market conditions and outcomes independently.
