Anthropic has submitted a draft Form S-1 registration statement to the U.S. Securities and Exchange Commission, becoming one of the first major AI developers to formally begin the process of going public. Filing an S-1 is the first official step toward an initial public offering, though the number of shares and pricing range have not been disclosed. The move comes as multiple AI and technology companies pursue public listings that could collectively test market capacity.
Anthropic Completes $65 Billion Series H Funding at $965 Billion Valuation
Shortly before the reported filing, Anthropic completed a major financing round. The company raised $65 billion in a Series H funding round at a post-money valuation of $965 billion. The round was backed by Altimeter Capital, Dragoneer, Greenoaks, and Sequoia Capital, making it one of the largest funding rounds ever completed in the AI sector.
Founded in 2021 by former OpenAI researchers including CEO Dario Amodei, Anthropic is known for developing the Claude family of AI models. The company has expanded across enterprise AI, coding assistants, and agent-based applications.
SpaceX Files S-1 for Nasdaq Listing, OpenAI Evaluates $1 Trillion Public Debut
SpaceX filed an S-1 registration statement in May 2026 and is expected to pursue a Nasdaq listing under the ticker SPCX. OpenAI is evaluating a public market debut that could value the company at approximately $1 trillion. Reports circulating at the end of May 2026 suggested OpenAI was preparing its own S-1 filing and targeting a public market debut later in the year.
Based on current estimates, the combined valuation of Anthropic, OpenAI, and SpaceX could reach between $3.7 trillion and $4 trillion when the companies enter public markets. Goldman Sachs has projected that the U.S. IPO market could raise as much as $160 billion in 2026.
Anthropic Operates Under Public Benefit Corporation and Long-Term Benefit Trust Framework
Anthropic operates as a Public Benefit Corporation and uses a Long-Term Benefit Trust framework designed to prioritize the company's mission alongside shareholder interests. Under this structure, the trust is expected to gain the ability to elect a majority of the board of directors over time.
That arrangement could limit the influence of ordinary shareholders on major strategic decisions. Public companies with comparable governance frameworks remain extremely rare, making Anthropic's approach a test case for future AI companies.
