Anthropic confidentially filed its IPO prospectus with the SEC on June 1, 2026, positioning itself for a potential debut above $1 trillion—which would make it one of three American companies to achieve this milestone in a single year. The Claude AI maker secured a $965 billion post-money valuation through its $65 billion Series H round led by Altimeter Capital, Dragoneer, Greenoaks, and Sequoia Capital, surpassing OpenAI's current valuation.
Revenue Growth Accelerates to Nearly 5x Year-Over-Year
Anthropic's revenue run-rate reached approximately $47 billion in May 2026, up from roughly $10 billion the prior year. This nearly 5x year-over-year growth demonstrates the company's rapid commercial expansion in the enterprise AI market. The company has not yet disclosed the number of shares to be offered or the IPO price range, with final terms dependent on market conditions at listing.
Claude Code Drives Competitive Advantage
According to CNBC reporting, Anthropic has "zoomed ahead of the field, largely thanks to Claude Code, its AI coding assistant." Industry executives at Google, OpenAI, and Anthropic increasingly characterize the frontier AI race as neck-and-neck, with companies making different tradeoffs around cost, speed, and computing resources. Anthropic's success with Claude Code has positioned it as a formidable competitor in the enterprise developer tools segment.
Historic Market Milestone in AI Sector
If Anthropic's IPO proceeds as anticipated, it would mark an unprecedented moment in U.S. capital markets. Never before have even one company, let alone three, gone public at valuations exceeding $1 trillion in a single year. The other two companies reportedly eyeing similar valuations are SpaceX and potentially OpenAI, signaling extraordinary investor appetite for leading AI companies.
