Should a contest be postponed, bets will stand if the rescheduled event occurs within 48 hours. If the contest is rescheduled to occur more than 48 hours following the original event, all bets in relation to the contest will be void.
In the event of a 'no contest' being declared, all bets will be made void, with the exception of selections where the outcome has already been unequivocally determined
If a fight is changed from 3 rounds to 5 or 5 rounds to 3, Match Betting bets will stand but all other markets will be voided.
Should there be a substitution for one of the fighters, bets on the original contest will be void.
The statistics provided by ufcstats.com will be used to determine the settlement of any bets which are placed on: (i) a given fighter to achieve a certain number of significant strikes, (ii) a given fighter to achieve a certain number of submission attempts (iii) a given fighter to achieve a certain number of takedowns.

Prices are offered for each fighter to win the fight and, in the event of a draw, all match bets will be void and stakes returned (for these purposes, draws will include fights which end in a 'majority draw').
Bets will be settled on the official result announced in the ring. Subsequent appeals/amendments do not affect settlement (unless the amendment was made due to human error when announcing the result).

If a fighter withdraws in the period between rounds, the fight will be deemed to have ended in the previous round for the purpose of "Round Betting" settlement.
For "Total Rounds" settlement purposes, 2 minutes and 30 seconds will represent half a round (if the round lasts for 5 minutes). For example, for a bet on "Over 1.5 rounds" to be a winner, the fight must last beyond 2 minutes and 30 seconds in round 2. If the number of rounds in a fight is changed after "Total Rounds" markets have been set, then all bets on these markets will be void.
If a fight is stopped at exactly 2 minutes 30 seconds of the round, bets on "Total Rounds" for that specific round will be made void.
Should the scheduled number of rounds be changed before the fight, all "Round Betting" bets will be made void.

This market is settled on the official times which are made available on www.ufc.com and the winner shall be settled according to whichever fight finishes in the least amount of time.
Our dead heat rules apply if two fights finish after the same amount of time.

Any fighter who wins before the fight goes its scheduled distance is declared the winner. If the fight goes to a decision, then the cumulative scores of all the judges will be used to determine the winner. If the fight is declared a 'no contest', this market will be void.

The winning selection will be determined based on the round in which the fight ends and the method of victory. Bets on this market will be deemed losing bets if the fight ends in a decision.

For "Will the Fight Go the Distance" (or similarly titled) markets, should the scheduled number of rounds change, this market will be made void.
If the fight is concluded before the stated rounds are over, then the fight has not gone the distance.

In the event of a Technical Decision, the winning fighter will be deemed to have Won by Points and not by stoppage in the round in which the fight ended.
