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, in dollars on a contract that pays $1 if the outcome happens: Polymarket from its live order book, Kalshi from its public API. Gap is Kalshi minus Polymarket. Thin books (spread over $0.10) and near-certain favorites are excluded from this table.

Edge after fees

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, as a percent of the $1 payout. Not advice; nothing here places orders.
