Will another country leave OPEC in 2026?

According to the latest prediction market data for the query “Will another country leave OPEC in 2026?”, traders have formed a strong consensus.

Currently, No is dominating the market with an overwhelming 86.5% chance of winning. Yes follows in second place at 13.5%. The betting volume for this specific market has already reached $108K, 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

• No (86.5%): Currently commanding the highest probability, No is heavily favored by the order book. Traders looking to back this outcome face a “Buy Yes” contract price of 87¢, signaling a high degree of market conviction.

🥈 Tier 2: The Primary Challengers

• Yes (13.5%): Positioned as the most viable alternative, Yes maintains a 13.5% chance of resolving true. Its “Buy Yes” shares currently trade at 14¢.

On April 28, 2026, the United Arab Emirates officially announced that it would withdraw from OPEC. You can read more about that here: https://www.reuters.com/markets/commodities/uae-says-it-quits-opec-opec-statement-2026-04-28/.

This market will resolve to “Yes” if another OPEC member officially announces its withdrawal from OPEC between market creation and December 31, 2026, 11:59 PM Gulf Standard Time. Otherwise, this market will resolve to “No”.

An official announcement made by any country that is an OPEC member at the time of market creation and has not already announced its exit will suffice, regardless of when the withdrawal is set to take effect.

Informal announcements, statements from unnamed sources, or leaks will not qualify.

This market’s primary resolution source will be official information from the respective governments; however, a consensus of credible reporting will also be used.

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.

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

• The Most Overvalued Outcome No currently trades at 86.5%, but our AI places its Fair Value at just 71.7%. This creates a large negative EV Gap of -14.8%, suggesting the crowd may be overhyping this outcome and driving the premium too high.
• The Best Value Play (Highest EV) Our model identifies Yes as the premium value opportunity on the board. While the market only assigns it a 13.5% trading probability, our AI’s Fair Value assessment sits at 28.3% — yielding an impressive +14.8% EV Gap.
