The Quick Answer
The UFC welterweight title odds on Kalshi price Islam Makhachev at 89 cents (an 89% market-implied chance) to still be the champion on December 31, 2026. That number repriced the night after he beat Ian Machado Garry at UFC 330 for his 17th straight win, the longest streak in UFC history. The only fighter the market gives a real chance of taking the belt from him is Carlos Prates at 11 cents; everyone else on the board sits at three cents or below. The full field, the reason the champion's own callout is doing the pricing, and the one date on the calendar that makes 89 cents a live number instead of a formality are below.
Makhachev just made history, and the prediction market treated it less like a coronation than an actuarial update. Beat Garry, break Anderson Silva's long-standing record, and the crowd that trades this market for money still marks an 11% chance you lose the belt before the year is out. That gap is the whole story, and it is lopsided. No single challenger owns all of the 11%, but one 170-pound knockout artist, the man the champion himself asked for next, carries far more of it than anyone else on the board. Read the board top to bottom and you are really reading one question: can anyone in this division solve a wrestler who just added a highlight-reel head kick to his game? The market's answer, and the fighter it is quietly betting on to try, is what the prices below spell out.
What Makhachev's UFC 330 Win Actually Changed
Start with what is now settled fact, because the market repriced off it overnight. At UFC 330 on Saturday, August 15, Islam Makhachev defended his welterweight title against Ian Machado Garry and won a unanimous decision, 49-46, 49-46, 48-47, dropping Garry with a head kick in the second round along the way. It was his 17th consecutive UFC victory, which passed Anderson Silva's 16-fight run from 2006 to 2016 and gave Makhachev the longest win streak in company history outright. He is now 29-1 as a professional and holds the belt he took from Jack Della Maddalena at UFC 322 last November.
The pivot: the fight market is settled and paid. The live money now sits in a different question entirely, who holds this belt on December 31, and that is the market almost nobody has priced up as a standalone read yet.
If you traded the fight itself, that market is closed. We broke down the pre-fight prices in our Makhachev vs Garry Kalshi odds guide, and Kalshi's winner contract settled at a dollar on the Makhachev side. What is still live is the forward market: who is holding this belt when the calendar flips. A different question with a different answer, and it is where the money is rotating now.
What The Kalshi Market Says About The 2026 Welterweight Title
Kalshi lists the welterweight crown under the event ticker KXUFCWELTERWEIGHTTITLE-26. Each contract is a separate yes/no on one fighter, and it resolves YES only if that fighter is the UFC welterweight title holder at 12:00 p.m. ET on December 31, 2026. Because every name trades with its own bid-ask spread, the listed prices add up to a little more than 100%, and the market can also settle on a fighter who is not currently listed if the belt changes hands unexpectedly.
Here is the board, fetched from Kalshi's public API around 9 a.m. ET on Sunday, August 16, 2026:
| Fighter | Last Trade | Implied Chance | Volume (Contracts) | Open Interest |
|---|---|---|---|---|
| Islam Makhachev | 89¢ | 89% | ~78,900 contracts | ~29,500 |
| Carlos Prates | 11¢ | 11% | ~30,000 contracts | ~17,300 |
| Michael Morales | 3¢ | 3% | ~21,500 contracts | ~14,700 |
| Kamaru Usman | 3¢ | 3% | ~6,600 contracts | ~5,400 |
| Sean Brady | 2¢ | 2% | ~2,700 contracts | ~2,400 |
| The Rest Of The Field | 1¢ each | 1% each | thin | thin |
The row that tells the story is the second one. Prates at 11 cents is not just the second-highest price on the board; he is more than three times the next name and the only fighter the market separates from the noise at all. Below him the board collapses fast: Michael Morales and Kamaru Usman at a token three cents, Sean Brady at two, and a penny apiece for Shavkat Rakhmonov, Leon Edwards, Ilia Topuria, Della Maddalena, Garry, and Belal Muhammad. A field that deep pricing this flat under the champion is the crowd saying the same thing a matchmaker would: there is Makhachev, there is one man with a puncher's chance, and then there is everyone waiting in line. If a cents-based board still feels unfamiliar, our explainer on what a prediction market price really means covers the mechanics, but the short version is that an 89-cent contract is the crowd saying 89%.
The 89% is the market's verdict. The fight tape and the champion's own microphone are where it came from.
The Fight Read Behind Makhachev's 89 Cents
Sharp MMA handicappers start with level of competition, and by that measure Makhachev's price explains itself. In back-to-back fights he took the title from Della Maddalena and then out-pointed Garry, a rangy contender whose only prior loss had come to Shavkat Rakhmonov. Those are not padded wins. Makhachev's core edge is the same one that carried him through a lightweight title reign: he lands better than three takedowns per 15 minutes, he defends around 90% of the takedowns attempted against him, and he barely gets hit on the feet, which is why the reverse path of out-wrestling him effectively does not exist in this division.
The UFC 330 head kick matters more than a single knockdown usually would, and it is worth being precise about why. The one honest knock on Makhachev at welterweight was that a bigger, longer striker might keep it standing and win minutes at range, the exact blueprint Garry was supposed to run. Instead Makhachev hurt him on the feet. A wrestler who can now credibly threaten a finish standing is a much harder title to pry loose than a wrestler who only wins on the mat, and the market moved his year-end number up accordingly. When the most complete fighter in a division adds the one tool people thought he lacked, "can anyone execute a game plan against him" stops being a live question for most of the roster.
Carlos Prates: The One Live Threat At 11 Cents
So why does one man escape the penny pile? Two reasons, and they point the same direction. The first is that the champion named him. Asked who deserves the next shot after UFC 330, Makhachev answered plainly: "If you ask who is more deserving, I think Carlos Prates." A callout from the belt-holder is the single biggest booking signal there is, and the market priced it in fast. The second reason is stylistic, and it is the only path on this entire board that does not require solving Makhachev's wrestling for 25 minutes. Prates does not need to win rounds. He needs one clean shot.
Prates is the No. 2-ranked welterweight and one of the most feared finishers in the sport: roughly 90% of his career wins have come by knockout, and every finish on his record has come by strikes rather than submission. That profile is the classic prediction-market shape of a live underdog. He is not an 11-cent fighter because he is likely to out-technique the champion over five rounds; he is an 11-cent fighter because knockout power is the one thing that turns a lopsided matchup into a coin flip for as long as the fight lasts, and a striker with his finishing rate carries that threat into any round.
Worked Example: What 89 Cents And 11 Cents Actually Cost
Kalshi charges a taker fee of about 0.07 × price × (1 − price) per contract, so the real cost of a position is a hair above its ask, and on the champion's heavily bought side the ask sits a cent above the 89-cent last trade. Buy the actual offer and the market's read gets concrete:
| Position | Ask + Est. Fee | Break-Even Chance | What It's Really Betting |
|---|---|---|---|
| Makhachev To Still Be Champ Dec 31 | 90¢ + ~0.6¢ = 90.6¢ | ~91% | He fights zero or one time and wins |
| Prates To Be Champ Dec 31 | 11¢ + ~0.7¢ = 11.7¢ | ~12% | He gets the shot and lands the shot |
The bottom row is where the whole board hides. Backing Prates here is not one bet, it is two things breaking right in sequence: the fight has to get made before the deadline, and then his power has to do in the cage what his 90% knockout rate says it can. Which is why the number is 11 and not 25. It is also why the value argument, if there is one, lives on the challenger's side rather than the champion's, because 90.6 cents on a favorite this heavy leaves almost nothing to win. Turning any of these cents back into fair American odds is a two-line exercise, and our de-vig walkthrough for Kalshi shows the math.

The Rest Of The Board, And Why It's SO Flat
The penny-and-token names are a useful tell, not filler. Michael Morales at three cents is the market's bet on a younger contender who has not yet earned the shot but could climb into it by year-end, which is exactly what a token price is for. Kamaru Usman at three cents is a legacy longshot the crowd will not quite zero out. Garry and Della Maddalena sit at a penny for the simplest reason on the board: Makhachev already beat both of them, so a rematch inside four months is close to a non-story. And the elite names you might expect higher, Rakhmonov and Edwards among them, sit in penny-to-token territory because none of them has a clear, announced line to the belt before December. That last point is what makes this board specific to Makhachev's reign rather than a generic favorite's: the two cheapest recognizable names are not unproven prospects, they are the last two men who got a crack at this belt and lost, which is why the market has to reach all the way down to an unbooked knockout artist to find anyone it believes can change the picture.
What Could Move This Price Before Year's End
A number this settled does not move on opinion, it moves on the schedule, and here the schedule is the whole risk. Makhachev has said he wants to fight again before Ramadan 2027, and ideally before the new year, which means a Prates defense could plausibly land inside this market's December 31 window rather than after it. That single fact is what keeps 89 cents honest. If the fight gets booked for late 2026, the champion's price will drift down as real title-fight risk gets priced in, and Prates will climb off 11. If it slips to January, the opposite happens: Makhachev's number creeps toward the high 90s as a year with no title change becomes a near-certainty, because a champion who does not defend cannot lose the belt in the cage.
That moment is when you want the tools already open. The instant a Makhachev–Prates date is announced, the fight itself gets priced across every book, and our live UFC odds screen lays those numbers side by side so you can shop the number across every major book instead of taking the first one you see.

FAQ
What are the UFC welterweight title odds for 2026 right now? As of Sunday, August 16, Kalshi prices Islam Makhachev at 89 cents (89% implied) to still hold the welterweight title on December 31, 2026, with Carlos Prates a distant second at 11 cents and the rest of the field at three cents or below. Prices reflect the market immediately after Makhachev's UFC 330 win over Ian Machado Garry.
Who did Makhachev beat at UFC 330, and what record did he break? He beat Ian Machado Garry by unanimous decision (49-46, 49-46, 48-47) to retain the welterweight title. It was his 17th consecutive UFC win, breaking Anderson Silva's record of 16 straight (2006-2016) for the longest win streak in UFC history.
Why is Carlos Prates the only challenger the market takes seriously? Two reasons. Makhachev named Prates as his preferred next opponent after UFC 330, which is the strongest booking signal there is, and Prates is a No. 2-ranked knockout artist who finishes roughly 90% of his wins. His power is the one path on the board that does not require out-wrestling Makhachev over five rounds.
Can I trade the Kalshi welterweight title market? Kalshi is a CFTC-regulated event-contract exchange open to users who are 18 or older and in an eligible state. Availability varies by state and changes over time, so check Kalshi's current rules before trading. Nothing here is financial advice.
Could Makhachev vacate the belt and go back to lightweight? He has signaled he is staying at welterweight for now and wants to defend before the new year, so a vacancy is not the market's base case. If it happened, the December 31 contract would resolve on whoever holds the belt at the deadline, which is part of why the field carries token pennies rather than zeros.
The Bottom Line On The 2026 Welterweight Title Market
Zoom back out and the UFC welterweight title odds are a portrait of a division with one obvious answer and one interesting question. The obvious answer is Makhachev, whose 17-fight streak, complete skill set, and brand-new standing knockout power distill into an 89-cent read that a deep field of contenders cannot dent. The interesting question is whether 11 cents is enough to pay for Carlos Prates, a knockout artist the champion himself asked for, whose entire case is that he only needs one moment the numbers say he creates more than most. You do not have to outguess the 89. You have to decide what the 11 is worth, know that a December booking is what makes either number move, and be ready with the right screen open the day the fight gets made.
