This guide covers what each market type is and how it settles (a No Contest or a canceled bout pays every side 50 cents), where the $106.7 million in settled UFC and MMA volume since April actually went, why MMA favorites at 70 cents or more have won only 61.2% of the time against two named upsets, and how to read a fight on 0xinsider before and during the walkout. ## A UFC fight on Polymarket Polymarket lists each fight as an event, titled with the card and the two fighters: "UFC 331: Arman Tsarukyan vs. Mauricio Ruffy (Lightweight, Main Card)." The moneyline is the fight's core market, and it pays $1 a share to whoever is declared the winner. 0xinsider's board resolves the platform's "MMA" category, which folds in every promotion Polymarket lists a fight for, so a PFL, ONE or Bellator card would render on the same board a UFC one does. Every fight open on the board as of this writing carries a UFC event slug; the board is named for the promotion that supplies its inventory today, not a promise that it always will. Around the moneyline sit method-of-victory, round and total-rounds markets. UFC 331's Tsarukyan-Ruffy fight listed 27 separate Yes/No markets: one moneyline, eleven round-of-victory markets (each fighter to win in each of five rounds, plus a "decision or draw" market), four method-of-victory markets, a separate "will the fight be won by decision" market, four round-of-finish markets, a go-the-distance market and five round totals. Not every fight lists all of them; a five-round title fight carries a fuller ladder than an early prelim. Read the market volume before you read anything else. On that same card, every dollar traded so far sat on the moneyline; every other market on the fight showed zero. That is not unusual for a UFC card, and the section below on where the money goes has the numbers across the whole sport. ## How a UFC fight settles The moneyline resolves to whichever fighter is officially declared the winner by the promotion. A draw, a technical draw, a No Contest, a fight that is never scored, or a bout canceled or postponed past its listed deadline settles the market "50-50": every share on both sides pays 50 cents, win or lose. The resolution source is the promotion itself, so a fighter pulling out on fight week does not leave a market stuck open once the promotion confirms the change. That 50-50 clause matters more in MMA than in most sports, because a No Contest, most often an accidental foul the referee cannot let the fight continue past, is a real outcome here in a way a tie almost never is in a team sport. It is not a frequent one, but it is common enough that a market's rules page is worth a glance on any fight with a history of eye pokes or headbutts. ## Method of victory: how the fight ends Method-of-victory markets come in two shapes. Some name a fighter and a method together, "Will Kamaru Usman win by KO or TKO?", which resolves Yes only if that fighter wins that way. Others ask about the fight as a whole regardless of who wins, "Will the fight be won by submission?" Both shapes resolve No on a draw or a disqualification, and 50-50 on a No Contest, an unscored fight, or a cancellation, the same clause the moneyline carries. KO/TKO covers a referee, doctor or corner stoppage, so a fight the doctor calls off between rounds counts the same as one the referee waves off mid-exchange. Submission covers a tapout, a verbal submission or a stoppage the referee rules for a fully applied hold. A fight that goes to the scorecards, unanimous, split, majority or a technical decision after a doctor stops it early on cuts, settles the decision side of these markets. ## Round props: when the fight ends Round-of-victory markets ask which round a named fighter wins in, "Will Arman Tsarukyan win in Round 3?", with one market per fighter per scheduled round and a companion "decision or draw" market for a fight that goes the distance. Round-of-finish markets ask only about timing, "Will the fight end before Round 2?", with no fighter named. Go the distance asks whether the fight reaches the final bell and is decided by the judges, resolving Yes on a scorecard decision or draw reached after every round and No on any finish before the last bell, including a technical decision or technical draw stopped early. All three families carry the same No Contest and cancellation clause as the moneyline. They are also the thinnest markets on a card: the settled-buy counts below show round and method props drawing a small fraction of the large-order volume the moneyline does, even on a full main card. ## Where the money actually goes From April 2 to September 14, 2026, 0xinsider recorded 5,375 large buys settling on MMA markets, $106.7 million in notional across 954 wallets and 355 fights. 5,119 of those buys, 95.2% of the count and $103.0 million of the notional, sat on the moneyline. Totals (round counts) drew 181 buys and $2.4 million; method-of-victory drew 33 buys and $0.6 million; go-the-distance drew 24 buys and $0.5 million. Round-of-victory, round-of-finish and method-of-finish markets each drew too few large buys to report a rate. The Tsarukyan-Ruffy card above is typical, not an outlier: 27 markets listed, one of them carrying every dollar traded. Check a market's own volume before sizing an order into it; a prop with $500 traded moves on a $1,000 buy in a way the moneyline does not. ## The favorite-longshot bias in MMA MMA is the sport where Polymarket's usual calibration breaks down. Across sports with at least 1,000 settled large buys, the gap between price paid and win rate holds within a point and a half of zero everywhere except MMA, where buyers who paid 57.9 cents on average won only 52.3% of the time, 5.65 points short, from April 2 to September 14, 2026 (5,375 buys). The gap concentrates in favorites: buyers of MMA favorites at 70 cents or more paid 80.4 cents on average and won 61.2% of the time, 19.14 points short, across 1,493 buys. Cricket sits on the other side of this same bias, covered in the guide at 0xinsider.com/learn/how-to-bet-on-cricket-polymarket: its favorites at the same 70-cent threshold beat the price by 4.62 points over the same window. Two fights carry most of that gap. UFC 328's Sean Strickland at 81.2 cents against Khamzat Chimaev drew 222 large buys worth $4.29 million and lost. UFC Freedom 250's Justin Gaethje at 80.0 cents against Ilia Topuria drew 148 buys worth $1.57 million and lost too. Together those two upsets cost favorite-backers $5.85 million, more than three times the $1.71 million spread across the next three largest favorite losses combined (UFC 327's Kelvin Gastelum and Paulo Costa, UFC 328's Jim Miller). The sport-wide number is a story about how badly a favorite can lose in a sport with no clock and one mistake, more than a rule about every fight. The chart below sets MMA's favorites beside every other sport with enough volume to measure, from the study at 0xinsider.com/research/favorite-longshot-bias-polymarket-sports. Soccer and tennis favorites won close to what they cost; MMA favorites paid the most and won the least. ## Live UFC: worse before the walkout, still worse during it Most of MMA's settled large buys land after the fight starts rather than before it: 3,933 of the 5,357 buys with a known fight time from April 2 to September 14, 2026, 73.4%, landed after the walkout. That does not turn the sport's calibration problem around. Buyers who bought before the walkout paid 57.8 cents on average across 1,424 buys and came in 10.18 points behind; buyers who bought once the fight was underway paid 57.9 cents across 3,933 buys and came in 4.02 points behind. In-play buyers do noticeably better than pre-fight ones, the same shape the cross-sport timing study finds, but neither group has beaten the price on MMA over this window. Treat that as a caution rather than an invitation: a cage fight can turn on one strike, and the live price often has not caught up to what just happened by the time an order fills. The study behind the cross-sport version of this number is at 0xinsider.com/research/when-large-sports-bets-land. ## What the sharp money shows in MMA 0xinsider grades every wallet from S to F on its settled record. From June 1 to September 14, 2026, wallets graded S, A or B placed 463 large MMA buys across 146 wallets, paying 58.9 cents on average and coming in 3.31 points ahead of the price. Wallets graded D or F placed 700 buys across 154 wallets, paying 57.5 cents and coming in 1.97 points behind. Both counts are well under the 500-per-cohort bar the cross-sport sharp-money study sets before it reports a sport on its own, so read this as a direction, not a settled rate: the graded wallets have been on the better side of MMA's price so far, by a smaller margin than the fight-level upsets above would suggest.
