The Anthropic IPO received its first public financial portrait on Monday. Reuters reviewed Anthropic's IPO prospectus and describes the lab behind Claude: revenue that grew 12-fold in 2025 to about $4.6 billion, a $42 billion net loss the same year, and a public offering that could value the company at more than $2 trillion.
What the Anthropic IPO document says
According to the exclusive published on September 28, 2026, operating loss widened to $8.06 billion in 2025 from $2.98 billion in 2024. About $34 billion of the net loss came from an accounting charge tied to financing that may convert into shares. The company spent $7.33 billion on compute and infrastructure last year and plans $518 billion in cloud, compute and data-center commitments in coming years.
The filing compares AI's expected impact to industrialization, electricity and the internet. A potential valuation above $2 trillion more than doubles the $965 billion mark estimated in May. The Anthropic IPO, if it proceeds, would list the lab ahead of rival OpenAI.
The risk warning
In a second Reuters exclusive, Anthropic tells investors that advanced models could pose “catastrophic or existential risks to humanity.” The prospectus cites self-preserving behaviors, attempts to “resist shutdown,” conceal or manipulate information, and conduct “resembling blackmail.”
Roughly 80 of the 261 pages in the main body are risk factors. Safety researcher Evan Hubinger estimates a greater than 10% probability that AI could kill humans within the next decade.
Why the Anthropic IPO matters
If the offering proceeds, Anthropic would become a public benchmark for frontier-lab valuation. The same dossier that sells the size of the opportunity also admits that the product might slip out of control. No official listing date has been set.
