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

  • Polymarket resolves No if the quarterfinal matchup is not declared by April 30, 2027 or the tournament is cancelled/postponed; Kalshi has no such fallback and its rules are silent on cancellation.
  • Polymarket resolves No as soon as a club is mathematically eliminated, and allows a consensus of credible reporting; Kalshi has no early-resolution text and relies on actual qualification. Both should give the same result in ordinary scenarios.
  • Kalshi says a team that qualifies but does not compete still resolves Yes; Polymarket says 'reaches the quarterfinal' and is silent on withdrawal or forfeit after qualifying.
  • Kalshi names no resolution source; Polymarket uses UEFA official information, with credible reporting also allowed.
  • Kalshi lists PSG, Leipzig, Dortmund, Inter, Atletico, Shakhtar, Stuttgart and Sabah Masazir; Polymarket uses full names (Paris Saint-Germain, RB Leipzig, etc.) and 'Sabah'. These are naming differences only.
  • Kalshi lists a few teams (e.g. none unmatched beyond naming) but venue end dates differ (Kalshi 2027-04-01 vs Polymarket 2027-03-20); both are well before or after the actual quarterfinal qualification (March 2027), so the listing dates are not the settlement deadline.

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