prediction.neg_risk_arbitrage
shallowio.github.parkyucheol-del/alphapipeline · Verify this server
Detect basket arbitrage in a Polymarket neg-risk (mutually-exclusive, multi-outcome) event - a full YES basket across all outcomes always settles to exactly $1, so a basket price away from $1 (after costs) is a near risk-free edge. Also returns buy/sell_basket_capacity_shares, the actual liquidity-bottleneck size executable right now, so this isn't just a top-of-book mirage. Polymarket only. Do not use for binary Yes/No markets (no basket to arbitrage) or for Kalshi (its Data ToS forbids this use). Paid in USDC on Base.
