FAQ
Does the market resolve if the game is postponed?
No. The resolution text says the market remains open until the game has been completed, so the outcome is decided only after play finishes.
What happens if the game is canceled?
If the game is canceled entirely with no make-up game, the market resolves 50-50 according to the resolution text.
Do overtime periods count toward the result?
Yes. The result is determined based on the final score including any overtime periods, so extra time can affect which side resolves.
How this page is made. Odds, volume and price history come from the AISA Polymarket APIs (Gamma events and CLOB prices-history). The analysis is written by a language model from those numbers and the market’s own resolution text only — any figure not in that data is removed. Probabilities are what traders are paying, not forecasts.
