On June 1, 2026, Anthropic, an artificial intelligence firm based in San Francisco, submitted a confidential filing for an initial public offering (IPO) with the U.S. Securities and Exchange Commission (SEC). This filing places Anthropic alongside other prominent tech companies like SpaceX and OpenAI, both of which also have plans to go public this year. Anthropic's IPO will be contingent on market conditions and other factors, with a possible public debut as soon as fall 2026. Recently, Anthropic surpassed OpenAI in valuation, reporting $965 billion compared to OpenAI's $852 billion. Founded by former OpenAI employees in 2021, Anthropic emphasizes AI safety, which has led to controversies, including a blacklisting by the Trump administration due to concerns over military use of its technology. The company is currently engaged in a lawsuit to reverse this blacklisting, while its growth in the private sector continues to accelerate.
