Market context

The underlying event is a middleweight bout tonight in Baku between Uzbek veteran Nursulton Ruziboev, 36–9–2, and Russian prospect Andrey Pulyaev, 10–5–0. Ruziboev enters with a four-fight UFC winning streak and back-to-back victories, including a knockout over Eric Spicely, while Pulyaev is a kickboxing specialist 6'4" with a solid but less decorated record[1][2][3]. The market currently shows 0% YES for Ruziboev winning, an extreme probability that contradicts his odds of –230 versus Pulyaev’s +190, suggesting a potential data error or mispricing rather than a genuine consensus[2].

Historically, similar extreme divergences between odds and crowd-implied probabilities have occurred when markets are illiquid or when bots fail to update after fight announcements, as seen in preliminary UFC cards where odds shift late but prediction markets lag. In past cases, such as the Fiziev vs. Torres prelims, odds corrected within hours while crowd probabilities remained static until manual intervention, framing today’s 0% as a likely technical glitch rather than a rational view[2][6]. Programmatic traders would flag this as a conditional order opportunity, setting alerts for odds updates and cross-referencing with official UFC feeds to confirm the discrepancy.

Key catalysts include the official fight result announcement expected within minutes post-bout, any late injury declarations, and the UFC’s resolution source confirmation by 2026-06-28T03:59:59.999Z. Traders should monitor real-time feeds from UFC Stats and Sherdog for immediate result updates, as well as any schedule changes that could trigger the 50–50 clause if the fight is postponed beyond 11 July 2026[3][4]. A recent Reddit discussion noted Pulyaev’s talent but questioned Ruziboev’s edge, reinforcing the need to verify whether the 0% reflects genuine doubt or a system error[9].

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.

FAQ

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

Do I need to KYC for this market?

Not under $1,500 of lifetime trading volume. Above that threshold, PolyGram triggers a quick verification flow that finishes in minutes.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
