Anthropic Files for IPO at $965 Billion Valuation
Anthropic confidentially filed an S-1 with the SEC on June 1, 2026, targeting an October IPO.
"Anthropic is about to go public at nearly $1 trillion. The AI gold rush isn't slowing — it's just getting a ticker symbol."
Anthropic, the AI safety company behind Claude, submitted a confidential draft S-1 registration statement to the U.S. Securities and Exchange Commission on June 1, 2026, initiating the formal process for a public offering. The filing follows a landmark $65 billion funding round led by Altimeter Capital, Dragoneer, Greenoaks, and Sequoia Capital, which pushed Anthropic's valuation to $965 billion — surpassing OpenAI's $852 billion valuation set in March 2026.
The company reported a $47 billion annualized revenue run rate, a staggering jump from $30 billion earlier in 2026 and just $10 billion in full-year revenue last year. The latest round includes $15 billion in previously committed capital, among it $5 billion from Amazon. No share price or count has been set; a listing window of October 2026 is being targeted.
The filing signals a historic moment for the AI industry. Goldman Sachs CEO David Solomon noted investors are in 'greed mode,' suggesting markets can absorb simultaneous IPOs from Anthropic, OpenAI, and SpaceX. With OpenAI having raised $122 billion in March and expected to file its own IPO, the public markets are bracing for a generational wave of AI listings.
An Anthropic IPO near $1 trillion validates enterprise AI as a permanent infrastructure layer, not a trend. Executives and marketers should expect accelerated AI product investment, increased pricing pressure, and new competitive benchmarks. Public market scrutiny will also force greater transparency on AI capabilities, safety, and revenue models.
