Anthropic aims to raise up to $69.3 billion in blockbuster IPO

What happened

On November 10, 2026, Reuters reported that Anthropic circulated, then immediately retracted, details of a potential IPO targeting up to $69.3 billion. The company told bankers the pricing information was inaccurate and that an updated filing would follow.

Context and impact

Anthropic filed a confidential S-1 on October 26, 2026, targeting a valuation of approximately $1.5 trillion. At $69.3 billion, the offering would surpass SpaceX's record 2026 IPO and become the largest in history. The backdrop includes the Fable 5.2 release, ongoing regulatory pressure, and a broader cooling in AI infrastructure financing.
