$1.2 trillion. That's the IPO valuation one investor says you'd need to assume just to justify OpenAI's most recent funding round — and that number is giving some backers pause.
The investor, who has funded both OpenAI and Anthropic, told the Financial Times that OpenAI's round only pencils out if you believe the company goes public at $1.2 trillion or higher. Anthropic, by contrast, sits at a current valuation of $380 billion — a figure that looks almost modest next to that projection.
The story here isn't just about big numbers. Anthropic has moved from underdog to credible rival in a way that's reshaping how investors think about the whole sector. A year ago, OpenAI's lead felt insurmountable. Claude has since become the preferred model for coding, legal work, and long-form document analysis among a growing share of enterprise customers. ChatGPT still dominates consumer mindshare, but the competitive gap has closed considerably.
When both companies are raising at steep valuations, investors who hold stakes in each have to pick which math they trust more. Right now, some are concluding that Anthropic's $380 billion tag represents a more realistic path to returns than a bet that OpenAI sustains the revenue growth a $1.2 trillion exit would require.
None of this means OpenAI is struggling — it still leads on user numbers and API revenue. But the era of treating OpenAI as the obvious pick with Anthropic as a distant second appears to be over. That competition between the two is also the main reason model quality keeps improving and prices keep falling for the people who use these tools every day.
