Anthropic Files Confidentially for IPO After $65 Billion Funding Round

The AI lab behind Claude accelerates its path to Wall Street amid soaring valuation and enterprise demand

Anthropic, the creator of the Claude AI models, has confidentially filed for an IPO following a record‑breaking $65 billion Series H round that valued the company at $965 billion. With annualized revenue approaching $47 billion and its first profitable quarter reportedly underway, Anthropic is positioning itself as the leading AI startup racing to public markets—just as corporate clients begin to push back on AI costs.

A Historic Funding and Valuation Leap

In late May 2026, Anthropic closed a staggering $65 billion Series H funding round, catapulting its post‑money valuation to approximately $965 billion—surpassing OpenAI’s $852 billion valuation from its March funding round . This nearly tripled the company’s valuation since February, when a $30 billion Series G round valued it at $380 billion . The intensity of investor demand underscores mounting confidence in Anthropic’s trajectory and its dominance in the generative AI market.

Confidential IPO Filing: Strategic Timing

On June 1, 2026, Anthropic confidentially submitted a draft S‑1 registration statement to the U.S. Securities and Exchange Commission, initiating its IPO process without publicly disclosing share count or pricing details . The company emphasized that any offering will hinge on market conditions and SEC review . Confidential filings offer companies flexibility to adjust before going public—a tactic now deployed by Anthropic to stay ahead in the high-stakes AI IPO race.
