Anthropic Files for Blockbuster IPO With $16.3B in First-Half Revenue and an $80.7B Net Loss

Anthropic publicly filed its S-1 prospectus on Monday, setting the stage for what analysts expect to be one of the largest IPOs in history. The Claude maker plans to list on the Nasdaq under the ticker ANT, with investors expecting a valuation of between $1.5 trillion and $2 trillion, and reports suggesting the company could seek roughly $100 billion in the offering. Pricing is targeted for mid-November, with one report pointing to a potential November 19 date.

The 407-page filing lays out a company growing at a staggering pace but burning through capital just as fast. Revenue for the first half of 2026 hit $16.3 billion, a roughly 1,300 percent increase from the same period a year earlier, driven by surging demand for its Claude chatbot and coding services. That works out to approximately $6.6 million in revenue per employee. At the same time, the company reported a net loss of $80.75 billion for the same six-month period, with nearly $650 billion in computing commitments on its books, underscoring the scale of infrastructure spending required to compete at the frontier of AI.

The prospectus carries an unusual risk disclosure: Anthropic warns investors that its own technology poses an existential threat to humanity, a stark caveat that reflects founder Dario Amodei's long-stated safety concerns and that has drawn both attention and controversy. The filing also notes the company will likely need substantially more capital beyond the IPO proceeds to fund ongoing model development and compute costs.

Goldman Sachs, JPMorgan and Morgan Stanley are among the underwriters set to share in the fees from what would be a landmark deal. The listing is expected to test investor appetite for a company whose losses are the direct counterpart to the compute revenue booked by its largest backers, Amazon and Alphabet, a relationship the Wall Street Journal noted exposes the complexity of AI-era earnings reporting. Anthropic had filed confidential IPO paperwork in early June 2026, weeks after rival OpenAI did the same.
