Market context

OpenAI’s private valuation would need to reach the listed threshold on an NPM print at any point before 31 December 2026, and the market is pricing that at just 7% YES, making it a clear underdog. That kind of probability usually sits around events where the target is far above the latest known mark and the path depends on one or two large financing steps rather than steady re-rating. OpenAI was last reported at a $852 billion post-money valuation in a March 2026 funding round, so the market is effectively asking whether a further jump can be marked before year-end rather than whether the company can merely hold current levels. On that basis, the consensus looks cautious, and the value case is for contrarians who think another private round or internal transfer price could land sooner than expected.

Comparable private-market steps show how quickly these numbers can move, but they also show how deal timing matters more than public headlines. OpenAI moved from a $500 billion employee share sale in October 2025 to an $852 billion round by late March 2026, while reports in late 2025 from the Wall Street Journal and others pointed to fundraising discussions around the $750 billion to $830 billion range before that. CMC Markets noted in 2026 that the company still had to complete a major pre-IPO financing round and that listing plans could slip, which matters because NPM marks are usually driven by actual transactions, not broad sentiment. The 7% price therefore reflects the risk that no qualifying private trade is printed before the deadline, even if valuation talk remains elevated.

We track Will OpenAI's valuation hit 2027 by December 31? on the five venues with material liquidity for prediction markets. Live odds come from the Polymarket Polygon order book — the only source that ships real-time data under an open licence. For Kalshi, Betfair and Manifold we list platform attributes (fee, KYC, settlement, payment) instead of fabricated odds, because their APIs use non-comparable contract definitions.

Resolution & payout

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.
