Market context

Bruno Silva, a Brazilian flyweight, faces Édgar Cháirez in a preliminary bout at UFC Fight Night: Muhammad vs. Bonfim on 6 June 2026. The conditional token for Silva victory is currently priced at zero on Polygon, reflecting either minimal trading activity or strong market conviction toward Cháirez. Settlement occurs within four hours of the event conclusion, with USDC payouts distributed to holders of whichever outcome token resolves affirmatively—or split 50-50 should the bout end in a draw, technical draw, no contest, or cancellation beyond 20 June.

Flyweight preliminary bouts historically exhibit volatile pricing on Polymarket, partly because fighter records at this weight class often lack the depth of data available for main-card competitors. Silva's recent form and Cháirez's record within the UFC's lower-ranked roster will determine whether the current zero-probability assessment reflects genuine analytical consensus or simply thin liquidity. Comparable preliminary matchups have occasionally seen dramatic repricing once fight week announcements confirm fighter health or late withdrawals.

Traders should monitor official UFC injury reports and weigh-in confirmations in the days preceding the event. Any announcement regarding fighter availability, weight-cut complications, or late-notice opponent changes would trigger immediate repricing of the conditional tokens. The preliminary slot also means this bout could be removed from the card entirely if the main event requires rescheduling, which would trigger the 50-50 resolution clause.

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

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.
