Recent secondary market trading on platforms like Forge Global has pushed Anthropic’s implied valuation to $1 trillion, already exceeding OpenAI’s $852 billion post-money mark from its March 2026 round. This shift stems from Anthropic’s annualized revenue run rate surging to roughly $39 billion—well ahead of OpenAI’s $25 billion—fueled by rapid Claude adoption and the April release of the Mythos model. Investors are now weighing a $30–50 billion raise at $900–950 billion that could close before summer, further widening the gap ahead of potential IPO filings. With these momentum-driven catalysts and limited near-term reversal signals, trader consensus prices in an 89% probability that Anthropic finishes 2026 at a higher valuation.

This market will resolve to “Yes” if, at any point, Anthropic's most recent public or private valuation is greater than OpenAI's most recent public or private valuation, by December 31, 2026 (ET). Otherwise, this market will resolve to “No”.
Private valuation refers to the valuation of a company as established in a completed funding round. Qualifying private valuations must be explicitly confirmed by the company whose value is observed, or an overwhelming consensus of credible reporting.
Public valuation refers to the company’s market capitalization (number of shares outstanding multiplied by the current share price).
The primary resolution source will be official communications from Anthropic and OpenAI; however, a consensus of credible reporting may also be used.
