Anthropic Secures Investor Bids Valuing It at $800 Billion, Prompting OpenAI Backers to

Anthropic’s latest fundraising round attracted bids that push its valuation to $800 billion, Bloomberg reports. The offers came from a mix of sovereign wealth funds and tech‑focused private equity firms, signaling strong confidence in the company’s growth trajectory.

The valuation surge eclipses OpenAI’s current $852 billion price tag, prompting several of OpenAI’s backers to reconsider their stakes, according to TechCrunch citing the Financial Times. One investor who backs both firms told the FT that justifying OpenAI’s latest $122 billion raise would require an IPO valuation north of $1.2 trillion, making Anthropic’s $380 billion pre‑money figure appear comparatively modest.

Anthropic’s revenue outlook has accelerated dramatically. The FT notes that annualized revenue climbed from $9 billion at the end of 2025 to $30 billion by March, driven largely by demand for its coding‑assistant tools. Secondary‑market data show Anthropic shares trading at a premium, while OpenAI’s stock trades at a discount.

Roy Luo of Iconiq Capital, which has invested over $1 billion in Anthropic and holds a smaller OpenAI position, told the FT there is a clear “number one and a number two dynamic,” and that the leader will win “disproportionately.” Luo added that his firm “picked” the frontrunner, underscoring the shifting investor sentiment.

OpenAI’s CFO Sarah Friar pushed back, emphasizing that the $122 billion private raise remains the largest ever, a sign of continued confidence, the FT reports. Nonetheless, the rapid rise of Anthropic’s valuation and revenue growth is reshaping the competitive landscape and forcing OpenAI’s backers to weigh their options anew.
