Market context

Joanderson Brito, a featherweight prospect, faces Jordan Leavitt in a preliminary bout at UFC Fight Night: Muhammad vs. Bonfim on 6 June 2026. The winner of this match will be determined by judges' scorecard, submission, knockout, or technical stoppage. In prediction markets, a YES share represents a bet that Brito wins; a NO share bets on Leavitt. The current 100% implied probability for YES suggests the market has priced in near-certainty of Brito's victory, though this extreme reading warrants scrutiny given both fighters remain active competitors with genuine upset potential.

Featherweight preliminary bouts in the UFC typically feature developing talent or fighters rebuilding records. Historical precedent shows that preliminary-level matches settle outcomes decisively more often than main-card fights—cancellations and no-contests occur at roughly 2–3% frequency across the promotion's lower-tier cards. The 100% probability reflects either extremely asymmetric fighter quality, recent injury news, or sparse market liquidity rather than genuine certainty. Traders should note that preliminary fights rarely attract significant late-breaking developments that alter fighter availability.

Settlement depends entirely on official UFC scorecards and announcements. The market resolves to 50-50 if the bout is postponed beyond 20 June, declared a draw, or ruled a no-contest. Traders should monitor UFC social media and official fight announcements in the week preceding the event for any withdrawal, injury, or rescheduling notices. The settlement window closes at 03:59:59 UTC on 7 June, allowing roughly 24 hours after the scheduled fight date for official results to be confirmed and recorded.

Resolution & payout

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
