Market context

Nursulton Ruziboev, the two-fight win streak middleweight, faces Andrey Pulyaev tonight at UFC Baku in a prelim bout where Ruziboev is the clear betting favourite. On Polymarket, this contract currently trades at 0% YES for Ruziboev winning, a price that starkly contradicts the -225 odds offered by major bookmakers like BetMGM and DraftKings, which imply a roughly 70% chance of victory for the Uzbek striker [1][2]. This divergence suggests the on-chain market is either mispriced or reacting to a specific, unconfirmed risk factor not yet visible in the public fight odds.

Historically, such extreme price dislocations in UFC prelim markets often precede late fight cancellations, medical suspensions, or weight-class discrepancies that bookmakers have already adjusted for but conditional token markets have not. Comparable cases from previous UFC Fight Nights show that when Polymarket prices a fighter at 0% despite strong bookmaker support, the resolution frequently hinges on a "No Contest" ruling or a technical draw rather than a decisive loss, as the market may be hedging against a non-scoring outcome [4][9]. The 50-50 resolution clause for draws or no contests remains a critical variable for traders assessing the current 0% valuation.

Traders should monitor the official UFC fight card updates and any pre-fight medical announcements, as a sudden withdrawal or weight miss could instantly invalidate the current pricing. Recent coverage notes Pulyaev’s solid talent but highlights his vulnerability to flash knockdowns, a factor that could swing the fight if Ruziboev’s submission specialist reputation is activated [3][9]. The settlement window closing on 28 June 2026 means any delay beyond 11 July triggers the 50-50 outcome, making the timing of the official result announcement a key catalyst for on-chain USDC liquidity movements on Polygon [6].

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

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.
