UFC cards carry live markets on both venues: Kalshi is a CFTC-regulated exchange available to traders in all 50 states, and Polymarket is open to US traders too. We lead with Kalshi for the broader US-listed slate and the deeper per-market book.

How do prediction-market MMA odds work?

Each fighter's price is the market-implied probability they win, quoted in cents (a 69¢ contract implies a 69% chance) and shown here as comma-free American odds. Unlike a sportsbook line, the contract settles at $1 if the fighter wins and $0 if they lose, so the price IS the probability.
