Anthropic could start marketing a record IPO in November

What happened: Bloomberg reported Thursday that Anthropic could begin marketing its IPO the week of November 9, with trading possible before Thanksgiving, and an investor day at its San Francisco headquarters on October 14. Prospective investors reportedly value it at $1.8 to $2 trillion, which would make it the largest IPO ever and the first time public markets price a frontier AI lab. A leaked prospectus showed $4.6 billion in 2025 revenue and nearly $42 billion in net losses. Anthropic is reportedly targeting around $100 billion in 2026 revenue and over half a trillion dollars in compute spending.
Austin's take: Austin calls the numbers astounding and says spending at this scale points to real economic impact from AI. He's glad a public listing would show Anthropic's finances and whether AI labs have a path to profitability, and calls Anthropic the biggest and most important AI company right now. He wonders whether investors will buy a company that warns about existential risk while building the technology, and whether investors are fatigued after a year of big AI deals.
Why it matters: A public Anthropic would put real, audited numbers on the economics of a frontier AI lab for the first time, which will shape how the whole AI business is judged.
What to do: If you invest, mark October 14 and the week of November 9, and read the actual prospectus for revenue, losses, and compute commitments rather than relying on headline valuations.
Not confirmed yet: Timing and valuation come from Bloomberg's sources and a leaked prospectus, not official filings. Austin was unsure of the context for a stat that all IPOs through 2025 total roughly $4 trillion, and he also referred to the $4 billion revenue figure as both 2025 and 2026.
