Who will be UFC Bantamweight champion at the end of 2026?

According to the latest prediction market data for the query “Who will be UFC Bantamweight champion at the end of 2026?”, traders have formed a strong consensus.

Currently, Petr Yan is dominating the market with an overwhelming 48.5% chance of winning. Merab Dvalishvili follows in second place at 43%, while Song Yadong sits in third with 2.1%. The betting volume for this specific market has already reached $476.8K, reflecting intense industry interest.

To better assess where each potential outcome stands, the market can be segmented into three distinct trading tiers based on implied probability and contract pricing:

🥇 Tier 1: The Dominant Leader

• Petr Yan (48.5%): Currently commanding the highest probability, Petr Yan is heavily favored by the order book. Traders looking to back this outcome face a “Buy Yes” contract price of 49¢, signaling a high degree of market conviction. This contract alone has generated $13.7K in volume.

🥈 Tier 2: The Primary Challengers

• Merab Dvalishvili (43%): Positioned as the most viable alternative, Merab Dvalishvili maintains a 43% chance of resolving true. Its “Buy Yes” shares currently trade at 43¢.
• Song Yadong (2.1%): Sitting in third place with a 2.1% probability, the market shows measured skepticism toward Song Yadong, treating it as an outside wildcard unless momentum shifts.

🥉 Tier 3: The Long-Tail Options (Combining for ~6.4%)

Beyond the top three choices, a wide field of macro variables and long-shot outcomes are being tracked. While their individual probabilities hover low, they represent crucial hedges for speculative traders:

• Alternative Options: This includes Sean O'Malley (0.8%), Umar Nurmagomedov (0.1%), and Cory Sandhagen (0.1%).
• Speculative Volume: Despite low statistical likelihood, certain long-tail contracts like Deiveson Figueiredo are still attracting notable interest.

This market will resolve according to the official UFC Bantamweight division champion on December 31, 2026 at 12:00 PM ET.

Only official UFC division champions will count. Interim champions will not count.

If the relevant belt is vacant at this market’s check time, or there is otherwise no champion in the specified division, this market will resolve to “Other”.

The primary resolution source for this market will be official information from the UFC (https://www.ufc.com/athletes).

While human consensus and speculative volume shape the broader prediction market, our quantitative algorithms offer a data-driven counter-perspective. By analyzing fundamental signals, underlying trends and historical distributions, our AI Valuation model calculates an independent “Fair Value” probability for each outcome.

Comparing this Fair Value against the current Trade Value uncovers major disparities — known as the Expected Value (EV) Gap. Contracts with a positive EV Gap represent statistically underpriced outcomes, whereas a negative EV Gap flags a potential market overreaction.

Top AI Alpha & Mispriced Arbitrage Opportunities

Based on the latest data model run, several key contracts stand out with significant deviations:

• The Most Overvalued Outcome Merab Dvalishvili currently trades at 43%, but our AI places its Fair Value at just 20.5%. This creates a large negative EV Gap of -22.5%, suggesting the crowd may be overhyping this outcome and driving the premium too high.
• The Best Value Play (Highest EV) Our model identifies Aiemann Zahabi as the premium value opportunity on the board. While the market only assigns it a 0.1% trading probability, our AI’s Fair Value assessment sits at 22.6% — yielding an impressive +22.6% EV Gap.
• Under-the-Radar Dark Horses Other notable discrepancies include Sean O'Malley (EV Gap: +18.8%) and Umar Nurmagomedov (EV Gap: +17.5%). These long-tail opportunities are heavily discounted by the live order books despite stronger statistical backing from our predictive model.
