UFC Bantamweight Champion on Dec 31, 2026 on Polymarket US

If Petr Yan holds the UFC Bantamweight Title on Dec 31, 2026 at 11:59 PM EST, this market will settle to Yes. Outcome verified by the UFC. Only the undisputed champion is recognized for resolution purposes; an interim champion does not qualify unless elevated to undisputed status by the governing body. This market resolves Yes if Petr Yan is the undisputed champion recognized by the governing body, having won the title before Dec 31, 2026 and not having lost it by 11:59 PM EST, wins the title on Dec 31, 2026 with the result standing at 11:59 PM EST, or is suspended but not stripped of the title. This market resolves No if Petr Yan is stripped of the title, loses the title before or on Dec 31

No independent base rate yet. Until we connect one (sportsbook consensus, forecasts, the score), the market's own price is the best public forecast, and the fee sits on top of it.

All but decided, says the market. The remaining cents are the price of the rare surprise, and the fee comes off them first.

Resting (maker) orders pay nothing; orders that take liquidity pay the fee. Formula: 9.5% × price × (1 − price) per share on orders that take liquidity (accounts under $10,000 of 30-day volume; 6.95% in a new account's first week and above $250,000). Break-even assumes you hold to settlement; trading out early pays the fee twice.

Who actually wins this market

  • Whoever posts the resting orders and collects the spread without paying a fee.
  • The venue, on every fee.
  • Not, on average, the person clicking buy because the chart is going their way. That was us.
