In its upcoming initial public offering (IPO), Anthropic plans to raise up to $64 billion, setting its valuation as high as $1.4 trillion. This filing with the US Securities and Exchange Commission indicates that the artificial intelligence company intends to sell 825 million shares of Class A common stock, with prices estimated between $70.00 and $78.00 per share.
Originally, expectations had been for the company to raise up to $100 billion, which would have marked the largest IPO on record. Analysts view Anthropic’s market debut as a significant measure of the sustainability of the AI spending boom currently benefitting the US economy.
The IPO is poised to launch in the week of November 16. On the eve of this announcement, Anthropic unveiled updates to its AI models, Fable 5.2 and Mythos 5.2, boasting a performance increase of 30 percent over previous versions.
Financially, Anthropic reported an impressive revenue of $17 billion for the third quarter, a sharp rise from $1.4 billion one year prior. The firm noted that its annualized run-rate revenue was approximately $81 billion as of October 31, 2026, reflecting a $10 billion increase since September 30.
While earlier estimates suggested a valuation potentially reaching $2 trillion, those projections have tempered in light of declining AI stock prices on Wall Street. Recent reports from prominent media outlets, including The Wall Street Journal and The New York Times, estimated Anthropic’s valuation to be between $1.3 trillion and $1.4 trillion.
