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

  • Who counts differs: Kalshi earnings-call markets count the company's representatives and the call operator; Polymarket counts anyone who speaks during the event, including analysts.
  • Word forms: Kalshi pays on the exact phrase and its plural or possessive form only; Polymarket's Mentions contract terms define their own form rules. Check edge words before treating a pair as hedged.
  • Scheduling: 'next' occasions are matched when both venues' scheduled dates are within 10 days (earnings calls) or 2 days (rallies, press conferences, PMQs). A rescheduled event can resolve differently on each venue.
  • Only outcomes with the same phrase set and the same minimum count are linked.

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