Polymarket traders have priced in an 8% probability that OpenAI's market cap will land between $1 trillion and $1.25 trillion at the close of its first trading day, implying a 92% expectation that the company will be valued below $1 trillion. The contract, which resolves on June 30, 2026, has attracted $205,000 in volume, reflecting modest but focused interest in the outcome.
No other prediction platforms currently offer contracts on this specific market cap range, limiting cross-platform comparison. The absence of data from Kalshi and Manifold means the Polymarket figure stands as the sole probabilistic signal, though traders should note the relatively thin liquidity. No specific external trigger was identified in today's news flow to explain the current odds.
The 92% probability of a sub-$1 trillion valuation contrasts with some private market estimates that have placed OpenAI's worth as high as $300 billion in secondary transactions. The gap between private and expected public valuations may reflect uncertainty around the company's revenue trajectory, regulatory pressures, or competitive dynamics in the AI sector as its IPO approaches.
