Kalshi and Polymarket price Holloway heavy favorite over McGregor at UFC 329

Updated 4d ago

Prediction markets Kalshi and Polymarket are pricing Max Holloway as the heavy favorite over Conor McGregor for their fight at UFC 329, which marks McGregor's return to the UFC, according to an article surveying both platforms' contracts. In a separate comparison, Kalshi is offering more value than traditional sportsbooks for the Ilia Topuria vs. Justin Gaethje matchup at UFC Freedom 250, where Topuria is heavily favored. Neither article provides specific odds, price differentials, or contract details for either event. The coverage comes as both platforms remain active in combat sports markets while navigating regulatory pressures elsewhere.

Why this matters?

Any persistent pricing gap between Kalshi and Polymarket on UFC markets gives arbitrage traders immediate profit opportunity. It also signals which platform's liquidity pool commands sharper combat sports pricing, steering where institutional and retail volume migrates ahead of the fall NFL season launch.

The bigger picture

Continues the running pattern of Kalshi and Polymarket pricing divergences on high-profile sports markets, after split NBA player odds and World Cup favorites already exposed arbitrage gaps between the two platforms' liquidity pools.
