Gable Steveson, the 2020 Olympic freestyle wrestling gold medalist and two-time NCAA heavyweight champion, opens his UFC career against Elisha Ellison on the UFC 329 prelims on July 11, 2026, as the biggest betting favorite in company history. The cross-platform moneyline is the most lopsided on the board: Steveson is priced above 90% implied on both Kalshi and Polymarket, and the two exchanges land within a point of each other. Ellison enters 5-2 as a professional but 0-1 inside the Octagon, ranked near the bottom of the UFC heavyweight division, so the question this market prices is how Steveson finishes, not whether. The live board above carries the current cross-platform prices; the bout settles the same night at T-Mobile Arena in Las Vegas.
Gable Steveson is the biggest betting favorite in UFC history entering his Octagon debut, and the prediction market reflects it. The heavyweight moneyline against Elisha Ellison is the widest on the UFC 329 board, with Steveson priced above 90% implied on both exchanges and roughly $1.28M in cumulative volume already staked across the pair. The only genuine market question is the method and pace of a Steveson win, not the winner.
Steveson vs Ellison Market Context
Steveson arrives with one of the most decorated wrestling resumes ever to cross into mixed martial arts: a 2020 Olympic freestyle gold medal at heavyweight and two NCAA Division I titles at Minnesota. He is 3-0 as a professional, finishing all three opponents inside the first round before signing with the UFC, and he trains alongside the Jon Jones camp. Sportsbooks have listed him anywhere from -2800 to -4000, a line that surpasses fellow wrestling converts Bo Nickal and Malcolm Wellmaker, who both closed near -2500. That sportsbook range implies a win rate in the high 90s.
Ellison is the reason the number is this extreme. He is 5-2 as a professional but 0-1 in the UFC, coming off a first-round knockout loss in his promotional debut last year, and he sits No. 38 of 40 in the UFC heavyweight rankings. The prediction market prices him as a live underdog rather than a formality, and that is the cross-platform read worth noting: the exchange price on Ellison is materially richer than the underdog price implied by Steveson's -2800 to -4000 sportsbook line. Kalshi and Polymarket agree with each other to within a point on both fighters, so there is no cross-platform arbitrage here, only a market that is slightly kinder to the dog than the books.
The fight sits on the prelims of a card headlined by Conor McGregor versus Max Holloway 2, which explains the heavy volume for an undercard bout. Line movement has been negligible; the moneyline has held near its open, with no meaningful intraday swing in either direction, consistent with a matchup the market considers settled.

Ellison's 0-1 UFC mark and No. 38 of 40 heavyweight ranking, the source of the lopsided line. The cross-platform value spot, where the exchange price on Ellison is richer than the sportsbook underdog price implied by a -2800 to -4000 favorite. Method and round, where the remaining market interest sits given the winner is close to fully priced.
