Anthropic submitted confidential paperwork to the US Securities and Exchange Commission on Monday, June 2, 2026, initiating an initial public offering process for the AI company behind the Claude models. The filing marks the first formal step toward a public market debut that could rank among the largest IPOs in history.
The San Francisco-based company, valued at $965 billion, announced the filing in a two-paragraph blog post, stating that the amount it seeks to raise and at what valuation have not yet been set. Anthropic said timing will “depend on market conditions and other factors.” The announcement followed a $65 billion fundraising round unveiled just days earlier.
Anthropic is led by CEO Dario Amodei and counts Amazon and Skype cofounder Jaan Tallinn among its major shareholders. The company reported annualized revenue of $47 billion based on sales from an unspecified period last month, though it has posted losses due to spending on cloud computing and staffing.
The IPO filing comes as competing AI companies pursue similar paths. OpenAI is rumored to be targeting its own public offering as soon as September 2026. SpaceX, which owns xAI, filed its own IPO paperwork in April, published it on May 20, and is targeting a June 12 stock market debut at a reported $1.75 trillion valuation. All three companies are seeking capital to fund the computing resources required to train frontier AI models.
A successful IPO could convert tens or even hundreds of Anthropic employees holding paper stakes into liquid millionaires or billionaires. However, the company’s structure as a public benefit corporation — which partly answers to a body it calls the Long-Term Benefit Trust — could complicate the process and affect its valuation.
Anthropic also faces a significant headwind: US Defense Secretary Pete Hegseth sanctioned the company earlier in 2026 under two government supply-chain laws, removing Claude from military and federal agency use. Executives have said the designations could cost the company billions in sales this year. Anthropic has filed suit to overturn them.
