Market context

Polymarket is pricing this UFC bantamweight-year-end contract at **31% YES**, so the market is leaning towards a non-Yan outcome or a title change by the December 31, 2026 check. In practical terms, holders are trading USDC on Polygon against conditional tokens that settle to the official UFC champion listed by the promotion at the market’s resolution time, with interim belts excluded and any vacant division resolving to **Other**. The reference point is the UFC’s own champions page, which currently lists **Petr Yan** as bantamweight titleholder.[7]

That 31% read is best compared with how volatile UFC title markets can be once the next defence, rematch, or injury cycle gets underway. Recent preview coverage from theScore framed Yan as the current champion while naming **Merab Dvalishvili** as the pick to finish 2026 with the belt, which captures the key risk for traders: a single result can flip the entire market, and title continuity is often less important than who gets booked next.[1] Cross-platform pricing also shows the market is not unanimous, with outside listings putting Yan, Dvalishvili, and Cory Sandhagen within striking distance rather than pricing a clear long-term favourite.[2]

The main catalysts are straightforward: UFC title announcements, fight booking dates, weigh-in outcomes, and any injury or cancellation that delays a defence past the settlement window. The official UFC champions page is the resolution anchor, so traders should watch for updates there after major cards and on any confirmed bantamweight title fight news.[7] In a market like this, the end-2026 holder is usually shaped less by rank alone than by whether the champion stays active enough to defend before the check 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

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.

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.

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.
