A no contest changes a fight's official result, not its paycheck. Both fighters are normally still paid their full contracted purse under the bout agreement, because that agreement guarantees pay for showing up and competing — it doesn't make payment conditional on how the fight is ultimately scored or ruled.
The bout agreement is what actually controls pay
Every UFC fight is governed by a signed bout agreement between the promotion and each fighter, which sets the purse for that specific fight. State and tribal athletic commissions that license the event generally require an unarmed combatant to be paid in full according to that agreement, separate from the final result. A no contest is a change to the official outcome — it erases a win or loss from both fighters' records — but it isn't a mechanism anywhere in that chain for reducing pay. The thing that was promised for fighting is what gets paid, regardless of which box gets checked on the result sheet afterward.
That's the opposite of how a lot of fans assume it works. Because a no contest can follow something that looks like misconduct — most commonly a failed drug test discovered after the fact, or an accidental foul that cuts a fight short before it can be scored — it's easy to assume the ruling itself comes with a financial penalty attached. It doesn't. The no contest and the paycheck are decided by two different processes that happen to sometimes get triggered by the same event.
Why people conflate the two
The confusion mostly comes from real cases where a fighter's pay WAS docked around the same event that produced a no contest, for a completely separate reason. Athletic commissions can withhold or reduce a fighter's purse for conduct violations — unsportsmanlike behavior, disciplinary issues, or (historically, in a widely covered 2018 case) attacking people outside the cage after the final horn. The Nevada commission withholding part of Khabib Nurmagomedov's UFC 229 purse after he left the cage to confront Conor McGregor's team is the most famous example: that fine was punishment for the brawl itself, decided through a separate disciplinary process, and had nothing to do with how the actual fight inside the cage had been scored.
When a no contest and a purse withholding happen to land on the same event, it's easy to read them as one connected penalty. They aren't. One is a commission's judgment about what happened in the cage during the scored portion of the bout; the other is a commission's judgment about conduct, assessed under its own disciplinary authority, which exists whether or not the fight result ends up a no contest at all.
What a no contest actually changes
A no contest wipes the result itself — no win, no loss, nothing added to either fighter's record beyond a notation of the overturned bout. It most often follows a fighter failing a post-fight drug test for a banned substance, an accidental low blow, eye poke, or clash of heads that ends the fight before it can be fairly judged, or occasionally a referee error serious enough that the commission steps in afterward. Point deductions handle most accidental-foul situations without needing to throw out the result entirely — a no contest is reserved for cases where the foul happened early enough, or was serious enough, that finishing the fight on the scorecards wouldn't be fair to either fighter.
None of those triggers are, by themselves, about money. A drug-test failure can separately trigger a suspension and, depending on the promotion's anti-doping policy, its own financial penalty — but that's a different rule working through a different process than the no-contest ruling on the result.
Win bonuses are a different story
The base purse is contractual and doesn't depend on the result, but some of the extra money around a fight is specifically tied to winning. A win bonus written into a contract, a sponsor incentive, or a step up to the next purse tier in a multi-fight deal can all be conditioned on getting an actual win on the record — and a no contest erases the win the same way it erases a loss. So a fighter who dominated a fight before it got overturned on a cut or a foul keeps the guaranteed show money, but can lose out on anything in the contract that was written to require a "W," not just a competitive performance. That's a real financial consequence of a no contest — it just comes from private contract terms, not from any commission rule about the no-contest ruling itself.
Discretionary bonuses work similarly. Performance-based awards that the promotion hands out after the card are chosen after the fact and aren't owed to anyone by contract, so there's no rule saying a no contest disqualifies a fighter from one — but in practice, a bonus is almost always attached to a fight that produced a clean result worth highlighting, and a fight that ended in a no contest rarely gets picked.
What a no contest does to bets
Sports betting on a fight that ends in a no contest follows the same logic as the purse: nobody's wager actually resolved, so sportsbooks generally void all bets on that fight and refund the stake rather than paying out either side. That's consistent with how a no contest works everywhere else — it's treated as if the official result never happened, not as a result that happened to favor neither side.
The practical takeaway for fans
If a card you're watching ends in a no contest, the safe assumption is that both fighters still get paid what their contract promised for that fight. Any story about a fighter losing money around a no contest is almost always a story about a separate disciplinary fine for conduct, a drug-related suspension under the promotion's anti-doping rules, or a withheld win bonus that was conditional on an outcome that no longer exists — not a penalty attached to the no-contest ruling itself. The record gets erased; the paycheck, in almost every case, does not.
