Anthropic’s aggressive pursuit of a $30–50 billion funding round at a $900–950 billion post-money valuation has emerged as the dominant catalyst lifting trader consensus for it surpassing OpenAI by year-end. The company’s valuation has already surged from $380 billion in its February Series G to levels exceeding OpenAI’s $852 billion post-money mark established in its March round, with secondary-market platforms showing Anthropic shares trading near $1 trillion. Sustained revenue growth at roughly 7–10× annually, recent model releases, and positioning ahead of a potential IPO continue to widen the gap in market-implied odds. Key upcoming milestones include final terms on the current raise and any further earnings trajectory updates through the second half of the year.

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.
