What happened
Anthropic is preparing to market an initial public offering as early as mid-November, with some prospective investors discussing a valuation as high as about $2 trillion, people familiar with the matter told Bloomberg.
What Bloomberg reported: Formal investor marketing could begin the week of Nov. 9, putting a listing before Thanksgiving (Nov. 26) in play, while a debut by year-end remains the broader expectation. Discussions are ongoing and the timeline could change, the people said.
Valuation talk: Prospective investors have discussed valuing the Claude maker at roughly $1.8 trillion to $2 trillion, Bloomberg reported. That would put Anthropic in rare company among tech listings; the company expects to match or beat the size of SpaceX’s IPO, according to the same reporting.
Why it matters
A Claude-maker listing at the discussed scale would be one of the largest tech IPOs ever — and a test of how public markets price AI growth against losses and safety risk.
What’s next
Watch for an official filing or Anthropic confirmation of marketing plans in November.
More context
Financial backdrop: Documents previously seen by Bloomberg showed about $4.6 billion in 2025 revenue, up from $386 million a year earlier, and a net loss near $42 billion — largely from a fair-value change in liabilities of more than $34 billion, Mint’s Bloomberg-based account said.
Market and safety context: AI firms face heightened scrutiny after high-profile agent-security incidents. OpenAI has postponed its own IPO plans; CEO Sam Altman has argued it would be ill-advised to go public now. Other recent tech IPO attempts have struggled or delayed, Bloomberg data cited by Mint noted.
Uncertainty: No S-1 details are public in these reports. Anonymous-source timelines often slip. The valuation range is investor chatter, not a priced deal.
