On a winner market with a tie outcome, such as soccer: “Exactly one settles at $1.00, the others at $0.00.”

When do markets settle?

Polymarket US says markets stay open until the outcome is known, and sports markets “often resolve shortly after the official result is posted.” It gives no fixed time. Settlement is delayed while an official result is under review. Under Rule 10.4 of the US Rulebook, the company may also review an outcome before settlement, and settlement then happens on the date the review concludes.

What if a game is postponed?

If a game is postponed before the start of play and rescheduled before the contract's expiration date, typically two weeks from the original event date, the official result of the rescheduled game governs. Polymarket US adds: “Postponed games do not automatically carry over to the rescheduled date.”

If the rescheduled game falls outside expiration, contracts on the original game settle at last fair market prices. The same goes for a game canceled and not rescheduled before expiration, as of when the cancellation was officially announced.

How do Combos settle?

A combo settles once. One losing leg takes it to $0, and a leg that can't resolve settles at its last fair market price and stays in the combo. Full detail on Polymarket US combos.

What the US Rulebook adds
