Market context

Alex Perez, the former UFC flyweight title challenger, faces Sumudaerji in a 125-pound bout scheduled for 30 May 2026 at UFC Fight Night: Song vs. Figueiredo. The Polymarket contract currently prices Perez's victory at 51%, reflecting near-parity between the two fighters in conditional token valuations on Polygon. Settlement hinges on official UFC declaration; any draw, technical draw, no contest, or postponement beyond 13 June triggers a 50-50 resolution, which traders should factor into their USDC positioning.

Perez's recent record provides the primary historical lens. His 2024–2025 campaign saw mixed results against ranked opposition, including a loss to Jasmim Jasmine in late 2024 that shifted market perception of his title prospects. Sumudaerji, by contrast, has maintained steady momentum in regional and UFC competition, though without the profile of a former title contender. The 51% implied probability suggests the market views Perez's experience and name recognition as offsetting Sumudaerji's recent form—a narrow edge that could shift sharply on injury announcements or late weigh-in complications.

Traders should monitor UFC official statements regarding fighter health and weight-cut status in the fortnight before the event. Any withdrawal or replacement would trigger immediate resolution mechanics. The Song vs. Figueiredo main card's prominence means this flyweight bout will receive standard broadcast coverage, reducing the risk of technical no-contest rulings. Conditional token holders should watch for late-stage odds movement on Polymarket itself, as sharp traders often signal injury or camp concerns through rapid repricing in the final 48 hours before fight time.

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.
