UFC and MMA Betting Rules: Draws, Half Rounds, Replacements and Method of Victory
Quick answer: a draw voids a bet on either fighter to win, but can make a method of victory bet a loser. Half a round is 2:30, and a finish at exactly 2:30 goes to the under. A replacement fighter voids every bet on the fight. A technical decision is a decision. If a five-round fight becomes three rounds, the winner bet stands and round bets may be void.
Most UFC bouts are scheduled for three five-minute rounds; title fights and main events go to five. A fight can end by knockout, referee or corner stoppage, submission, decision, disqualification or no contest, and late replacements on fight week are common. Each of those outcomes settles bets in its own way.
This guide compares the published MMA rules of two UK-licensed bookmakers, Sky Bet and Midnite, and works through the markets that cause the most disputes. It is about how bets are settled, not who to back. Boxing uses three-minute rounds and different draw and half-round rules: see our boxing betting rules guide.
Two UK bookmakers, side by side
Both rule sets were read on 9 November 2026 (Midnite's MMA page is dated 9 July 2026). They agree on replacements, half rounds and technical decisions, and differ on postponements and on what a change in the number of rounds does. Your own bookmaker's MMA rules are the binding text.
| Situation | Sky Bet | Midnite |
|---|---|---|
| Draw on a winner bet | Fight Outright void if the draw was not a selection. Live fight winner: losers. | Winner has no draw option: a draw, majority or technical draw voids it. |
| Draw on method of victory | Live method: losers. Pre-fight method void on a DQ or no contest. | All bets lose unless a draw method is offered. |
| Substitute fighter | All bets void. | All bets void. |
| Postponed or moved | Void if postponed because a fighter pulls out, or moved to another UFC event. | Void if not held within 48 hours. |
| Number of rounds changed | All void except Fight Outright, fight treble and head-to-head stats. | Winner, outright and method stand; total rounds and round betting void; go the distance on the new distance. |
| Stopped at exactly the half-way point | 2:30 exactly: under wins. | 2:30 exactly: under wins. |
| Corner stoppage or retirement between rounds | KO/TKO/Stoppage; fight ended in the previous round. | Fight ended at the end of the previous round. |
| Technical decision | Settled as a decision victory. | Counts as Decision; go the distance = No. |
| No contest | Void, except bets already decided. | Void unless the market is already determined. |
Half rounds: where over and under meet
Total rounds lines in MMA are set at half rounds, and with five-minute rounds half a round is 2 minutes 30 seconds. The line is crossed at the half-way point of the next round. Both bookmakers settle a finish at exactly that second the same way. Sky Bet: "If the fight is stopped at exactly 2 minutes and 30 seconds of the designated round, the 'under 1.5 rounds' will be the winner."
| Line | Over needs the fight to pass | Used in |
|---|---|---|
| Over/under 1.5 rounds | 2:30 of round 2 | 3 or 5 rounds |
| Over/under 2.5 rounds | 2:30 of round 3 | 3 rounds: a decision is over |
| Over/under 3.5 rounds | 2:30 of round 4 | 5 rounds only |
| Over/under 4.5 rounds | 2:30 of round 5 | 5 rounds: a decision is over |
That tie rule is the opposite of the one Midnite uses for boxing, where a stoppage at exactly 1:30 of a three-minute round is settled as over. Someone who bets both sports with the same book can win one bet and lose the other on the same split second. A fighter who does not answer the bell for the next round has lost at the end of the previous round, so a corner stoppage after round 1 is under 1.5.
Draws and method of victory
Draws are rare in MMA, but when one happens it splits the markets. A winner bet with no draw option is void: the stake comes back. A method of victory bet on KO/TKO, submission or decision has no void route at Midnite: "all bets will be settled as losers unless a draw method is offered".
The bets: 10 pounds on Fighter A to win at 1.60, and 10 pounds on Fighter A by decision at 3.00. The judges score the fight 29-28, 28-29, 28-28: a split draw.
Settlement at Midnite: the winner bet is void and returns 10 pounds. The decision bet loses, because no draw method was offered. Net result: minus 10 pounds on a fight Fighter A did not lose.
The stoppage group is wide: Sky Bet's KO/TKO/Stoppage includes a referee stoppage, a stoppage by the doctor or the corner, and a fighter retiring through injury. Submission includes a tap-out and a technical submission, where the referee stops the fight because a fighter is caught in a hold. A technical decision counts as a decision at both bookmakers. At Sky Bet a disqualification or a no contest voids the method of victory market.
Fight week: replacements, postponements and round changes
A replacement opponent voids every bet on the fight at both bookmakers, however late it is announced. Midnite keeps bets alive through a postponement only if the fight is held within 48 hours. Sky Bet voids bets if the fight is postponed because a fighter pulls out, or if it is moved to a different UFC event.
A late replacement in a main event sometimes comes with a change from five rounds to three. Sky Bet then voids all bets on the fight except Fight Outright, fight trebles and head-to-head statistics. Midnite keeps the winner, outright and method markets, voids total rounds and round betting, and settles go the distance on the new distance. The same fight, the same news, two different sets of void bets.
Fight cards and accumulators
Fight cards invite accumulators across five or more bouts, and a void fight counts as odds of 1.00. A 10 pound treble at 1.50, 1.70 and 2.20 returns 56.10 pounds if all three win (1.50 x 1.70 x 2.20 = 5.61). If the 1.70 fight is cancelled after a replacement, the bet becomes a double at 1.50 x 2.20 = 3.30, returning 33.00 pounds.
Heavy favourites in MMA are short, and stacking them raises the bookmaker's margin with every leg. Our accumulator calculator handles void legs, the margin calculator shows the overround on a two-way fight price, and the odds converter translates American moneyline prices such as -250 into decimals.
Frequently asked questions
What happens to a UFC bet if the fight is a draw?
A bet on either fighter to win is void and the stake is returned, as long as the draw was not offered as a selection. Midnite says a draw, including a majority or technical draw, voids its Winner market, and Sky Bet voids Fight Outright bets on a draw if the draw was not a selection. Method of victory bets are different: Midnite settles them as losers on a draw unless a draw method is offered, and Sky Bet's live fight winner and live method markets also settle as losers on a draw.
What does over 1.5 rounds mean in UFC betting?
UFC rounds last five minutes, so half a round is 2 minutes 30 seconds and over 1.5 rounds needs the fight to pass 2:30 of round 2. A finish at 2:29 of round 2 is under; at 2:31 it is over. Both Sky Bet and Midnite say that a fight stopped at exactly 2:30 is a winner for under 1.5 rounds. For over 2.5 rounds in a three-round fight the line is 2:30 of round 3, and a decision is always over.
Is a UFC bet void if a fighter is replaced?
Yes. At both bookmakers read here a substitute fighter voids all bets on the fight. Midnite also voids bets if the fight is postponed and not held within 48 hours, and Sky Bet voids bets if the bout is postponed because a fighter pulls out or is moved to a different UFC event.
How is a technical decision settled in MMA betting?
As a decision. When a fight is stopped early, usually by an accidental foul, and sent to the judges' scorecards, Sky Bet settles it as a decision victory and Midnite classes technical decisions as Decision in method of victory. Because the fight was stopped before the full distance, Midnite settles its fight to go the distance market as No.
What happens to UFC bets if a fight changes from five rounds to three?
The winner bet stands, round-based bets may not. Sky Bet voids all bets on a fight whose number of rounds differs from the one it was priced with, except Fight Outright, fight treble and head-to-head statistics markets. Midnite keeps Winner, Fight Outright and method bets, voids total rounds and round betting, and settles fight to go the distance on the new distance.
