Get Arb Live
Real-time arbitrage opportunities between Polymarket binary markets and Binance spot.
See backtest/arb_engine.py for the math:
- Polymarket YES mid → market’s implied probability
- Binance spot + 5s-bar realised σ → log-normal model probability
- Mismatch + EV after fees + spread filter → tradeable rows
Returns rows sorted by expected net PnL per share (highest first). Empty list when no edges clear the filters — that’s normal during quiet markets or when bots are actively repricing.

Query Parameters
Minimum |market_yes − model_yes| in probability points. Below this, the mismatch is dominated by fees and noise. 0.04 = 4pp is the practical floor.
Required range:
0 <= x <= 0.5Realised-vol estimation window in seconds. Shorter = more responsive to current regime; longer = less noisy.
Required range:
60 <= x <= 3600Comma-separated tickers to scan.
Comma-separated Polymarket event types to scan.
Required range:
1 <= x <= 200
