Market context

Song Yadong faces Deiveson Figueiredo in a bantamweight bout scheduled for 30 May 2026 at UFC Fight Night. The 0% implied probability on Song reflects either minimal trading activity or a technical artefact of low liquidity rather than genuine market conviction. With settlement five weeks away, the market remains in early formation, and any substantive movement will likely follow official fight confirmation and fighter health updates.

Figueiredo arrives as a former two-time UFC flyweight champion with proven finishing ability across multiple weight classes, though his recent record shows mixed results at bantamweight following his move up. Song, the Chinese prospect, has compiled a strong record but faces a significant step up in competition against an opponent with championship pedigree. Historical comparisons suggest markets pricing established champions against rising contenders typically favour the proven commodity, though Song's youth and undefeated record in the UFC create genuine uncertainty that 0% fails to capture.

Traders should monitor official UFC injury reports and fighter statements through early June, as any withdrawal or replacement would trigger a 50-50 resolution. Weigh-in confirmation on 29 May will signal both fighters' readiness. Recent UFC scheduling patterns show Fight Night events rarely postpone beyond their announced dates, reducing the likelihood of the extended postponement clause. The settlement window extends to 13 June, providing a fortnight buffer for any scoring disputes or technical complications requiring official UFC clarification.

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.
