Kalshi prices, volume and trade history as of Wednesday, September 2, 2026, about 7:30 a.m. ET, pulled from Kalshi's public market data. Sportsbook lines come from the OddsShopper live odds board at the same time. Every number here moves, so re-check the live quote before acting on any of it.
The Quick Answer
Kalshi's UFC Paris market has Salahdine Parnasse at 81 cents bid, 82 ask to beat Dan Hooker on Saturday, September 5, with Hooker at 19 bid, 20 ask. In payout terms, a 20-cent Hooker contract turns $100 into about $500 before fees if he wins and nothing if he does not, which is where the 4-1 in the title comes from. The sportsbooks are harsher on Hooker than the exchange is, and the two-to-three-cent gap between them is the whole story below: what the price is really about, which venue is cheaper for each side once fees are counted, and the two settlement rules that catch fight traders off guard.

A Debut Priced Like A Title Defense
The lightweight main event at Accor Arena on Saturday is a strange thing to price. One fighter has never stepped into the Octagon, and he walks out last on a main card that starts at 3 p.m. ET on Paramount+. The other has headlined it three times and been ranked in the division for most of a decade. And the market has decided, across about 200,000 contracts of trading on the Hooker board alone, that the newcomer is the one with the roughly four-in-five chance.
None of that is a knock on Parnasse. He arrives 23-2, a two-time KSW featherweight champion and a KSW lightweight champion who defended that belt four times, undefeated at 155 pounds, and riding five straight stoppage wins into his UFC debut in front of a home crowd in Paris. The question the price forces is a different one, and it is the question sharp MMA handicappers ask before any other: what level of competition built those numbers, and what level built Hooker's?
Hold that question. The fight facts answer it in a way the two markets disagree about, and the disagreement is the trade.

What 81 Cents Is Really Pricing: A Chin, Not A Résumé
Start with Hooker, because the price is more about him than about the man across the cage. He is 36 years old, 24-14, and he has been stopped in back-to-back fights: an arm-triangle submission by Arman Tsarukyan in the second round last November, then a second-round TKO by Benoît Saint Denis at UFC 325 on January 31. Go back further and the pattern hardens. Each of his last five losses ended in a finish. The last time Hooker lost on the scorecards was the five-round decision to Dustin Poirier in June 2020, and every defeat since (Michael Chandler, Islam Makhachev, Arnold Allen, Tsarukyan, Saint Denis) came inside the distance.
UFC.com's fighter stats say why. Hooker lands 4.82 significant strikes a minute and absorbs 4.94, a negative differential on a fighter whose whole game is standing in the pocket and trading. A 36-year-old who gets hit more than he hits, whose last five defeats all ended in a finish and who has been stopped in his last two, is a durability question before he is a skill question. That is the outlier in this matchup, and it is what an 81-cent price on the other side is really buying.
Now the other half of the level-of-competition question, because it cuts the opposite way. Look at the names on Hooker's loss column: Poirier, Chandler, Makhachev, Tsarukyan, Saint Denis. Those are champions, title challengers and ranked contenders. Hooker's record was built against the best of the best; his most recent wins, over Mateusz Gamrot and Jalin Turner, were both split decisions. Parnasse's 23-2 was built in KSW and, most recently, on the MVP MMA card on Netflix in May, where he stopped Kenneth Cross in the first round. His five-fight stoppage run (Valeriu Mircea, Wilson Varela, Marian Ziółkowski, Marcin Held, Cross) is real and impressive. It is also a run built entirely outside the UFC's rankings. The rule is to discount records built on weaker opposition and credit fighters who lost to elites, and by that rule Hooker's 24-14 is a better résumé than it looks and Parnasse's 23-2 is a slightly worse one.
Then there is the physical matchup. Hooker is 6-foot with a 75-inch reach; Parnasse is 5-foot-10 with a reach of about 73 inches, and he has fought a chunk of his career one weight class down at featherweight. Parnasse also has seven submission wins across his MMA career, which matters against a Hooker who stops takedowns at a respectable 77% but whose defense frays once he is standing in front of you (he blocks only 49% of the significant strikes thrown at him) and whose last two losses ended with Tsarukyan choking him and Saint Denis stopping him on strikes late in the second round. So the fight has three live paths: Parnasse cracks an aging chin, Parnasse drags him down and finishes there, or Hooker uses the reach and the experience to make a debutant fight 25 ugly minutes in his first five-round bout under UFC lights.
Which of those paths the price weights most is exactly where Kalshi and the sportsbooks part ways.
The Kalshi Board, And The Side Everyone Is Actually Trading
Kalshi lists this fight as a winner-only market under the event ticker KXUFCFIGHT-26SEP05HOOPAR: one yes/no contract per fighter, paying $1 to the winner's side and nothing to the other. There are no method, round or distance contracts on the exchange. The board opened on August 30 and has traded like a main event should.
| Contract | Bid | Ask | Last Trade | 24-Hour Volume | Open Interest |
|---|---|---|---|---|---|
| Dan Hooker | 19¢ | 20¢ | 20¢ | ~101,000 contracts | ~195,500 |
| Salahdine Parnasse | 81¢ | 82¢ | 81¢ | ~2,400 contracts | ~39,700 |
Stare at Hooker's row, and look at the volume. About 200,000 contracts have traded on the Hooker side lifetime (the open interest column counts the ones still held) against roughly 40,000 on Parnasse, and the last 24 hours were even more lopsided: 101,000 to 2,400. The lopsided count says less about belief than it looks. On Kalshi, buying "no" on Hooker is the same position as buying "yes" on Parnasse, so the Hooker contract is simply where this fight's liquidity lives. If you want to trade either side, the Hooker board is the deep one, and the penny-wide spread on both contracts is as tight as a Kalshi fight market gets. If bids, asks and settlement are new territory, what a Kalshi price actually means covers the mechanics in five minutes.
The trade history tells you something the snapshot cannot. Across the 1,000 most recent trades, from Monday night through Wednesday morning, the Hooker contract never left a 17-to-20-cent band, and the average price paid drifted up, from about 18.9 cents over the first day of that window to about 19.1 over the second. A day earlier the quote was 18 bid, 19 ask; now it is 19 and 20. It amounts to a slow, steady nudge toward the underdog, and it puts the exchange a step further from the sportsbooks than it was on Monday.
Nineteen Sportsbooks, And The Sharp Ones Don't Agree With Kalshi
Here is the promised gap. At the moment the Kalshi board above was captured, the OddsShopper live board carried this fight at 19 sportsbooks. The favorite ranged from -556 at the softest book to -750 at the harshest; Hooker ranged from +400 to +475, and the widest book, TheScore, posted both extremes at once. The mainstream numbers sat in the middle of that: DraftKings at -625 and +455, FanDuel at -700 and +440, Caesars at -600 and +430, and Pinnacle, the book sharps use as a reference price, at -622 and +465.
Strip the vig from every pair and the 19 books span roughly 16.5% to 19.1% on Hooker. The sharp reference prices anchor the low end, Pinnacle at 17.0% and DraftKings at 17.3%, while the books closest to the exchange are the loosest ones: Ladbrokes at 19.1%, Hard Rock at 18.8%, Bally at 18.5%. Kalshi, at 19 to 20, is trading with the soft end of the board rather than against all of it, and it sits two to three cents above the sharp number. A gap that size between the sharp books and a liquid exchange on a main event is unusual. Three weeks ago, in the Makhachev vs Garry Kalshi market, the exchange and DraftKings matched to the decimal once fees were counted. Here the exchange is the venue giving the veteran more respect. The full method for turning any book's pair into fair cents is in our de-vig walkthrough for Kalshi; the short version is that Pinnacle's -622 is a stronger statement about Hooker's chin than Kalshi's 81 cents is.
The gap is also where the line has been heading for weeks. The opening numbers on this fight were in the neighborhood of Parnasse -357 to -400 and Hooker +275 to +300, depending on the book. The books have marched to -625 since. Kalshi's board did not exist until August 30, so its 81-cent price was born after most of that move, and it has still not caught all the way up.
A Worked Example: What Each Side Costs After Fees
A price gap is only worth something if it survives the fees, so run the arithmetic. Kalshi charges a trading fee on each taker order that works out to roughly 0.07 times the price times one minus the price, per contract. At 82 cents that is about one cent; at 20 cents it is about 1.1 cents. Add the fee to the ask and compare it to the break-even win rate baked into the DraftKings line:
| Position | Kalshi Ask + Fee | Break-Even On Kalshi | DraftKings Line | Break-Even At The Book |
|---|---|---|---|---|
| Parnasse To Win | 82¢ + ~1.0¢ = ~83.0¢ | 83.0% | -625 | 86.2% |
| Hooker To Win | 20¢ + ~1.1¢ = ~21.1¢ | 21.1% | +455 | 18.0% |
Read the top row first. Backing Parnasse costs about 83 cents all-in on Kalshi, against an 86.2% break-even at DraftKings and 84.8% even at the softest book on the board. The favorite is cheaper on the exchange, by about three points against DraftKings, and that is a real difference on a position where you are laying better than four-to-one either way.
The Hooker row flips it. A $100 stake at an effective 21.1 cents buys about 474 contracts and returns roughly $474 if he wins. The same $100 at +455 returns $555, and $575 at the best number on the board. At today's numbers the sportsbook is the cheaper ticket on the underdog, by a wide enough margin that the choice is not close. If I like Hooker, I am buying him at a book; if I like Parnasse, I am buying him on the exchange, and the arithmetic above is the entire reason. The structural reason the two venues split like this on every fight is laid out in Kalshi fees vs sportsbook vig; the practical lesson is that whichever fighter you like, you should be pricing him at both venues, and across every book, before you pay. Our live UFC odds screen does exactly that in one look, with all 19 books' Hooker and Parnasse prices side by side so you shop the number instead of taking the first one.
The Two Settlement Rules That Actually Matter Here
The exchange contract and the sportsbook moneyline are the same bet right up until the fight refuses to produce a winner, and fights do that more often than the price implies. Kalshi's rules for this event handle it two ways worth knowing before you click.
- A Draw Or No Contest Settles Both Sides At 50 Cents. If you bought Parnasse at 82, an accidental eye poke or a clash of heads that stops the fight early hands you back 50 cents on the dollar, a 32-cent loss per contract, plus the fee you paid to get in. A sportsbook would typically void the moneyline and refund the stake. On a fight where the favorite is priced in the 80s, this rule is a hidden tax on the favorite's backers that almost nobody prices in.
- A Postponement Does Not Close The Market. If the fight is delayed, the contracts stay open and settle on the rescheduled bout as long as it happens within two weeks. Only a cancellation, or a delay longer than that, resolves the market at a fair price under exchange rules. The listed close time on the board is September 19, exactly two weeks after fight night, for that reason.
The fee rule earlier and the no-contest rule here point the same direction: the exchange is the better place to buy the favorite on price, and the worse place to hold him through an early stoppage that goes to the referee instead of the judges. Kalshi operates under CFTC regulation as event contracts, not sports betting, is open to traders 18 and over, and its state availability differs from the sportsbooks' and changes often, so check Kalshi's own eligibility page, current as of September 2026, before assuming your state is live.
What Could Move 19 Cents Before The Cage Door Closes
A number this well-traded does not move on opinion between now and Saturday, and the tape says how firmly it has settled. Of the roughly 103,000 contracts that changed hands across both boards in the last 24 hours, about 98% traded on the Hooker contract, and all that flow moved the average price paid by two-tenths of a cent, from 18.9 to 19.1. Enormous volume with almost no repricing is what a market that has made up its mind looks like. Remember, too, that this board did not exist until August 30, after the sportsbooks had already marched from the -357-to-400 openers to -625, so Kalshi has never had to price this fight from scratch; it inherited the books' number and then drifted a step away from it.
So the signal to watch is the band. The Hooker contract has not printed below 17 cents or above 20 since Monday night. A trade outside that band before the walkouts, in either direction, would be the first real information the market has produced since it opened, and each direction means something specific in sportsbook terms. A print below 17 is the exchange conceding to Pinnacle's number. A print above 20 is the gap with the sharp books widening past three cents, on a fight where every book has been moving the other way for weeks. The weigh-in is the one scheduled event between now and then that could force either print.
After that comes the fight, and the market does not close at the opening bell: the contracts trade through the bout and are expected to settle that night (Kalshi lists the expected expiration at 9:40 p.m. ET Saturday; the September 19 date is only the postponement backstop). The path questions from earlier become price questions in real time. If Parnasse plants Hooker early and starts working from the top, the 81 has room to run toward the 90s; if Hooker stuffs the first attempts and the reach starts landing, the 19-cent side reprices just as fast. A debutant fighting his first 25-minute UFC main event in front of a home crowd, against a veteran whose best path is making the fight long and ugly, is the exact matchup where a mid-fight price says more than a pre-fight one.

The Bottom Line On Hooker Vs Parnasse Kalshi Odds
Zoom back out. Two regulated markets are pricing the same fight, and they disagree by about three cents on whether a 36-year-old who absorbs more than he lands, stopped in his last two, gets a 17% or a 20% chance against a 23-2 debutant whose record was built outside the UFC. The exchange is the venue that remembers Hooker's losses came to Poirier, Chandler, Makhachev, Tsarukyan and Saint Denis. The books are the venue that remembers how those fights ended. The result is a clean split you can use: the favorite is cheaper on Kalshi, the underdog is cheaper at the books, and the no-contest rule tilts the favorite's risk back toward the sportsbook. Re-run that arithmetic Saturday morning at whatever the live quotes say, because a gap between markets this liquid rarely survives to the walkouts untouched.
