Check settlement rules before comparing contracts. Matched outcomes may settle differently. These venues also report end dates more than 48 hours apart; event identity does not mean the contracts close or settle together. These are stored prices; record update times do not certify live quotes. Differences exclude fees and available size.

Known rule differences between venues

  • Kalshi lists scores only up to 5-3 for wins and draws up to 4-4, with no catch-all outcome. Polymarket lists a grid up to 5 goals per side plus 'Any Other Score'. Scores such as 5-4 or 5-5 and 6+ goals have no matching Kalshi outcome, and Kalshi's rules do not say how unlisted scores resolve.
  • Polymarket outcomes for 0-1 through 0-5, 1-2 and similar scorelines (Roma wins) map to Kalshi Roma wins, but Kalshi omits some of these (e.g. Roma 5-4) and Polymarket omits 6+ goal scorelines; unlisted scores resolve differently ('Any Other Score' vs. unspecified on Kalshi).
  • Polymarket resolves to 0-0 if the match is canceled with no make-up game and waits if it is postponed; Kalshi rules say nothing about postponement or cancellation, so a 0-0 outcome could pay differently.
  • Polymarket specifies a resolution source hierarchy (official stats, then Flashscore, Sofascore, credible reporting) and a 50-50 fallback; Kalshi's rules text names no source.

A shared identity alone does not make a price difference executable.
