Market context

Alex Perez and Sumudaerji are scheduled to meet in a flyweight bout on the main card of UFC Fight Night: Song vs. Figueiredo on 30 May 2026. The Polymarket contract currently prices both outcomes at 50–50, reflecting genuine uncertainty about the matchup. Settlement hinges on official UFC declaration; any draw, technical draw, no contest, or cancellation beyond 13 June triggers a 50–50 split of the conditional token pool on Polygon.

Perez, a former title challenger at 125 pounds, has competed consistently at elite level but faced mixed results in recent campaigns. Sumudaerji represents the rising challenger archetype—younger, with momentum from recent victories. Historical precedent suggests that when Polymarket prices flyweight bouts at even odds, the market typically reflects genuine stylistic uncertainty rather than information asymmetry. Recent UFC Fight Night events have seen main-card flyweight contests resolve decisively more often than not, though upsets remain common enough to justify neutral pricing when fighter records and form are closely matched.

Traders should monitor official UFC injury announcements and weigh-in confirmations in the week preceding 30 May. The Song vs. Figueiredo headline's prominence means this event will receive standard UFC media coverage; any late fighter withdrawal or significant weight-cut complications would shift conditional token flows. Polymarket's settlement window closes 31 May at 03:59:59 UTC, allowing roughly 24 hours post-fight for official UFC scorecards and decision announcements to propagate before resolution mechanics trigger.

Methodology

We track UFC Fight Night: Alex Perez vs. Sumudaerji (Flyweight, Main Card) on the five venues with material liquidity for prediction markets. Live odds come from the Polymarket Polygon order book — the only source that ships real-time data under an open licence. For Kalshi, Betfair and Manifold we list platform attributes (fee, KYC, settlement, payment) instead of fabricated odds, because their APIs use non-comparable contract definitions.

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.
