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 event takes place in an unconfirmed location, with the preliminary card scheduled to commence several hours before the main event. Silva and Cháirez are both established competitors in the 125-pound division, though neither ranks among the division's elite contenders. The fight's outcome will be determined by official UFC scoring and judging protocols, with resolution contingent on a decisive winner being declared by the promotion.

Preliminary-card flyweight matchups historically carry lower market liquidity and wider probability spreads than main-card bouts, reflecting reduced media coverage and analyst attention. The current 0% implied probability for Silva suggests either minimal trading activity or a strong consensus favouring Cháirez amongst early market participants. Comparable preliminary fights at UFC Fight Night events have shown significant probability shifts once fighter injury reports, weight-cut complications, or late-notice opponent changes emerge within 48 hours of competition.

Traders should monitor official UFC announcements regarding fighter health status and any schedule adjustments through early June. The settlement window closes at 03:59:59 UTC on 7 June, allowing approximately 24 hours post-fight for official result confirmation.

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

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
