Resolution criteria on PolyGram: 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, 2026, 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.
PolyGram is an on-chain prediction market where you trade YES or NO outcome shares with real USDC on Polygon. For this market, buy YES if you believe the event will happen, or NO if you think it won't. Your maximum loss is your stake — winning shares pay $1.00 each at resolution. Unlike sportsbooks, there is no house edge: prices are set by supply and demand from other traders and reflect the crowd's real-time probability.
Market outcomes
| OpenAI acquired before 2027? | 8% YES | 92% NO |
OpenAI remains a private company with a complex ownership structure centred on a non-profit board, making an outright acquisition or merger a structurally challenging transaction. The 8% implied probability on Polymarket's order book reflects the market's assessment that such a deal remains unlikely within the next two years, though the resolution criteria—which include announced agreements regardless of completion—create a lower threshold than a fully closed transaction would.
Historical precedent offers limited direct comparisons. Major AI acquisitions have typically involved smaller, earlier-stage companies rather than frontier labs with significant operational independence and investor bases. Google's acquisition of DeepMind in 2014 for an estimated $500m–$650m occurred when the company was earlier-stage; since then, large AI firms have generally remained independent or pursued strategic partnerships instead. OpenAI's valuation (estimated at $80bn+ following recent funding rounds) and its entrenched position as an independent entity with substantial institutional backing make a full acquisition materially different from historical precedents.
The most plausible catalysts for a Yes resolution would involve either a major strategic shift by OpenAI's board, a significant financial distress scenario, or an unsolicited approach from a well-capitalised acquirer. Traders should monitor quarterly funding announcements, leadership changes, and regulatory developments that might alter OpenAI's independence calculus. Recent reporting on OpenAI's governance tensions and capital needs provides context, though no current signals suggest imminent acquisition discussions. The market's 8% probability reflects this low-baseline scenario weighted against the structural barriers to such a transaction completing within the settlement window.
Resolution is handled by the UMA optimistic oracle on Polygon. A proposer submits the outcome, a two-hour dispute window opens, and if no one stakes a counter-claim the payout is final. Contested outcomes escalate to UMA token-holder voting. Payouts clear in USDC to the winning side.
The mechanics for trading "OpenAI acquired before 2027?" are the same as any other PolyGram event contract. Each YES share resolves to $1 if the event happens, or $0 if it doesn't. The current price between 0¢ and 100¢ is the market's probability estimate, set live by the order book.
$3K in lifetime turnover and $3K of resting liquidity puts this market in the below the median by volume for ai contracts on PolyGram. Order-book depth is thin — large orders may need to be split across the book or executed as limit orders.
The market has been open for 6 months — the price has had time to stabilise as new information arrived.
Higher-volume markets tend to have tighter spreads and faster price discovery — meaning the displayed YES/NO percentages are more likely to reflect the true crowd-implied probability rather than a single trader's directional view.
As of today, traders on Polymarket price this outcome at 8%. The number updates continuously as the order book clears. PolyGram mirrors the same live odds with locale-aware formatting and USDC settlement.
