How this is built
Every event listed on both exchanges is matched outcome by outcome: games by team codes and date, multi-outcome markets by name. Prices are mid-market: Polymarket from its live order book, Kalshi from its public API. Gap is Kalshi minus Polymarket in percentage points. Thin books (spread over 10¢) and near-certain favorites are excluded from this table.
Net edge
Buy one side on one venue and the other side on the other, both at the ask. Edge is $1 minus total cost minus taker fees, Kalshi ⌈0.07·P·(1−P)⌉ per contract and Polymarket 0.05·P·(1−P) on sports. Not advice; nothing here places orders.
