Artificial intelligence startup Anthropic has filed paperwork with the U.S. Securities and Exchange Commission (SEC) for an initial public offering (IPO), becoming the first of the major generative AI firms to formally begin the process of listing on public markets.
The company announced on Monday that it had submitted a draft registration statement to the SEC, though details including the number of shares to be offered and the proposed price range have yet to be determined.
In a statement, Anthropic said the filing gives it the option to proceed with a public offering once the SEC completes its review process, adding that the timing of any IPO will depend on market conditions and other factors.
The filing marks a significant milestone in the rapidly evolving artificial intelligence sector and positions Anthropic ahead of rival OpenAI in the race to become the first major frontier AI company to debut on public markets.
A statement by the company published on its website says,
“Today, Anthropic, PBC confidentially submitted a draft registration statement on Form S-1 to the U.S. Securities and Exchange Commission for a proposed initial public offering of our common stock”.
“This gives us the option to go public after the SEC completes its review. The proposed initial public offering will depend on market conditions and other factors”.
“The number of shares to be offered and the price have not yet been set. This announcement is being published under Rule 135 of the Securities Act of 1933, as amended. It is not an offer to sell securities; nor is it a solicitation of an offer to buy them. Any offers, solicitations of offers to buy, or any sales of securities will be made only in accordance with the registration requirements of the Securities Act.”
The development comes just days after Anthropic reportedly raised $65 billion in fresh funding at a valuation of $965 billion, surpassing OpenAI’s last reported valuation of $852 billion in March 2026.
Anthropic’s rapid rise has been fueled largely by strong enterprise demand for its AI products, particularly Claude Code, its software development and coding assistant platform. The company has expanded its product portfolio aggressively in 2026, launching new offerings targeted at businesses and developers while continuing to upgrade its flagship Claude family of models.
According to company disclosures, Anthropic’s annualized revenue run rate exceeded $47 billion at the beginning of May, up sharply from $30 billion in April and approximately $9 billion a year earlier, underscoring the explosive growth being experienced across the generative AI industry.
The IPO filing also intensifies competition between Anthropic and OpenAI, which have emerged as the two dominant players in the global artificial intelligence race. Both companies are competing for enterprise customers, developer adoption, computing resources, and investor capital as demand for AI-powered tools accelerates worldwide.
Anthropic has also expanded its strategic partnerships with major technology firms, including Amazon, Apple, and Microsoft, through cybersecurity and AI infrastructure initiatives aimed at strengthening software security and enterprise adoption.
In 2025, Alphabet Inc. deepened its strategic investment in Anthropic, committing an additional $1 billion to the AI startup as part of its broader push to strengthen its position in the artificial intelligence race.
According to reporting by the Financial Times, the latest investment followed earlier funding commitments, including a $2 billion package in 2023, which comprised an initial $500 million cash injection and a further $1.5 billion staged investment.
