About this market

Context

This market will resolve to “Yes” if credible reporting confirms that any entity enters into an agreement to acquire OpenAI (or the nonprofit that controls OpenAI) by December 31, 2025, 11:59 PM ET. Otherwise, this market will resolve to “No”. Mergers where OpenAI is subsumed by another entity will count toward a "Yes" resolution. An announced agreement between OpenAI and an acquiring entity will qualify for a “Yes” resolution, regardless of whether the acquisition is ultimately completed. The primary resolution source for this market is official information from Sam Altman and/or OpenAI however a consensus of credible reporting will also be used.

How trading works

Polymarket uses a central limit order book (CLOB) model — you can buy or sell shares of any outcome at the current market price, or place limit orders at your target price. All positions are settled in USDC when the market resolves.

Resolution

Markets resolve through UMA's Optimistic Oracle. After the market closes, a proposer submits a resolution, followed by a 2-hour dispute window. If no dispute is raised, the resolution is accepted. Disputed markets go to UMA token holder vote.
