Unless a rule includes a provider-specific exception below, it applies to all three providers (UDX, Kalshi, Crypto/Nadex).
What happens if a fighter is disqualified, withdraws, or forfeits?
If a fighter forfeits, withdraws from consideration, or takes any other official action to remove themselves from the fight (including withdrawing before the bout takes place), that fighter's market resolves to No.
If a fighter is disqualified before the market expires — even after the fight has concluded — their market also resolves to No. If the disqualification causes another fighter to be reported as the official winner, the market resolves based on whichever fighter is reported as the official result.
What happens if a fight is postponed?
If a fight is postponed past its scheduled date (for example, due to injury or another emergency), the market stays open and resolves after whichever comes first:
The official result is reported, or
Two weeks after the fight's originally scheduled date.
What happens if a fight is cancelled?
If a fight has been cancelled and is not scheduled to begin within 48 hours, all markets on the fight will resolve to the last fair market price as determined by the exchange.
What happens if a fight is suspended?
If a fight is suspended once it's underway, the market stays open and resolves after whichever comes first:
The official result is reported, or
Two years after the fight's originally scheduled date.
What happens if a fight ends in a draw?
A fight that ends in a draw resolves to No for each competitor.
