Anthropic Files for IPO as AI Competition With OpenAI Intensifies

Anthropic has confidentially filed for a U.S. initial public offering (IPO), becoming the first of the leading AI developers to take a formal step toward entering public markets.

Anthropic Moves Ahead in AI IPO Race

The filing places Anthropic ahead of OpenAI in the race to launch one of the most anticipated stock market debuts in the technology sector. While the company did not reveal the size or timing of the offering, the move signals confidence in investor demand for artificial intelligence businesses.

Anthropic recently completed a funding round that valued the company at approximately $965 billion, more than doubling its valuation from earlier this year. The company is best known for its AI products, including the coding-focused assistant Claude Code.

Investors Watching AI Valuations Closely

Market analysts view the planned listing as a major test for public investor appetite toward AI companies. A successful debut could influence how future AI firms are valued and how investors assess revenue growth, profitability, and long-term potential.

Growing Competition Between Anthropic and OpenAI

The filing comes as competition among AI leaders continues to accelerate. OpenAI has also been reported to be preparing IPO plans, though Chief Executive Sam Altman recently said the company would go public only when the timing is appropriate.

Anthropic’s rapid growth has attracted support from major institutional investors, including Blackstone, Brookfield, General Catalyst, Insight Partners, and D1 Capital Partners.

With several large technology companies preparing stock market listings, analysts believe firms are competing for investor capital while market conditions remain favorable. The IPO market has strengthened in 2026, with global fundraising reaching its highest level since 2021, creating an attractive environment for major technology offerings.
