Song Yadong and Deiveson Figueiredo are scheduled to meet in a bantamweight bout on the main card of UFC Fight Night on 30 May 2026. The current order book on Polymarket reflects a 50-50 split, indicating traders see this as a genuine toss-up. Settlement hinges on official UFC declaration of a winner; any other outcome—draw, technical draw, no contest, or cancellation beyond 13 June—resolves the market at 50-50.
Song Yadong has compiled a 19-6 record with notable wins over Marlon Moraes and Julio Arce, establishing himself as a credible contender in the division. Deiveson Figueiredo, a former flyweight champion, moved up to bantamweight and has shown mixed results at the heavier weight class. Historical matchups between established contenders and former champions at different weight classes typically favour the fighter more accustomed to the division, though Figueiredo's championship pedigree and technical skill set complicate straightforward prediction.
Traders should monitor injury reports and official weigh-in confirmations in the weeks preceding the event, as both fighters have experienced layoffs that could affect conditioning and performance. Recent UFC scheduling patterns suggest the promotion is unlikely to cancel established main-card bouts unless serious circumstances arise. Any significant training camp updates or fighter statements released closer to the fight date could shift the current equilibrium, particularly given the even split suggests limited conviction either direction among current market participants.
This market settles from the official outcome published at https://www.ufc.com/events. A proposer submits the final result to the UMA optimistic oracle on Polygon; the two-hour dispute window closes and payouts clear in USDC.

$1K in lifetime turnover and $1K of resting liquidity puts this market in the below the median by volume for sports contracts on PolyGram. Order-book depth is thin — large orders may need to be split across the book or executed as limit orders.

The market has been open for under a month — fresh enough that information asymmetry remains a real factor.
Higher-volume markets tend to have tighter spreads and faster price discovery — meaning the displayed YES/NO percentages are more likely to reflect the true crowd-implied probability rather than a single trader's directional view.
