Anthropic is at last planning to go public. And a slew of well-known hedge funds stand to benefit.
On Monday, the company behind the Claude AI models filed IPO plans confidentially with the Securities and Exchange Commission, the first step toward offering its shares publicly. The company has not yet set the number of shares it plans to sell or at what price. Even so, the announcement of Anthropic’s IPO plan comes after the company reported on May 28 that it had raised $65 billion in a Series H funding round led by Altimeter Capital, Dragoneer, Greenoaks, and Sequoia Capital, valuing the company at an eye-popping $965 billion.
Several prominent hedge funds that had invested in previous funding rounds of Anthropic also participated in the latest financing. They include Coatue Management and D1 Capital Partners, as well as D.E. Shaw Ventures.
The funding was Anthropic’s third financing round in less than nine months.
In February, Anthropic raised $30 billion in a Series G funding round led by Coatue and GIC, Singapore’s sovereign wealth fund, valuing Anthropic at $380 billion. At the time, the company said its run-rate revenue reached $47 billion as the number of global enterprise customers grew.
The Series G round also included D.E. Shaw Ventures, Dragoneer, Founders Fund, ICONIQ, and MGX. Other significant hedge fund investors included Appaloosa, D1 Capital, and Whale Rock Capital.
On September 2 of 2025, Anthropic announced a Series F fundraising of “just” $13 billion led by ICONIQ. The financing valued Anthropic at $183 billion. Significant hedge fund investors in the round included Coatue and D1 Capital.
D1 also participated in Anthropic’s $3.5 billion Series E financing in early May 2025, which valued the company at $61.5 billion.
Coatue, D1, and D.E. Shaw are investors in OpenAI as well, having participated in the company’s recent $122 billion funding round, which valued the company at $852 billion. Other hedge fund investors included Appaloosa.
Over the years, Tiger Global Management has participated in at least three funding rounds of OpenAI, according to Crunchbase.
Anthropic’s filing follows the blockbuster IPO announcement from SpaceX and comes before rival OpenAI has made official plans to go public itself in what is shaping up to be perhaps the most momentous year in IPO history.
