Market context

Aiemann Zahabi faces Sean O'Malley in a bantamweight contest scheduled for 14 June 2026 at UFC Freedom 250, headlined by Topuria versus Gaethje. The fight will be scored under standard UFC rules; a draw, technical draw, no contest, or cancellation beyond 28 June triggers a 50-50 resolution. Official UFC records determine the outcome.

O'Malley enters as the favoured fighter at 62% implied probability, reflecting his ranking trajectory and recent form. Zahabi, a Canadian prospect training under Firas Zahabi at Tristar Gym, has built a 13-4 record but remains less established at elite bantamweight level. Historical comparisons suggest that when unranked challengers face rising contenders in similar matchups, the market typically prices the known commodity 55–70% depending on recent performance data and injury status. The current 38% for Zahabi aligns with underdog positioning for a fighter still building his UFC résumé.

Traders should monitor fight announcements through official UFC channels and social media for injury withdrawals or schedule shifts, which would trigger the 50-50 resolution clause. Weigh-in results and any last-minute coaching changes at Tristar or O'Malley's camp may shift sentiment in the final week. Deposit and withdrawal friction matters here: traders using Klarna or SEPA transfers should account for settlement timing, as the market closes 15 June at 03:59 UTC—less than 24 hours after the event concludes. USDC on-ramp availability will determine how quickly capital flows into the book as fight week approaches, directly affecting liquidity depth for late-market adjustments.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.

Resolution & payout

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
