Anthropic has filed its public S-1 prospectus for an initial public offering on Nasdaq under the ticker ANT. The document does not say how much the company intends to raise or what valuation it will seek, though the listing could arrive later in November, according to reporting cited by WIRED.
The filing shows revenue of more than $16 billion in the first half of 2026, compared with about $4.5 billion during all of 2025. Anthropic says more than 11,900 customers spent at least $100,000 over the past 12 months, including roughly 250 that spent $10 million or more.
Growth has not produced a profit. Anthropic reported an $80.7 billion net loss for the first half, up from $13 billion in the same period a year earlier. Prospective investors will need to separate expanding product demand from the accounting and capital costs behind that loss.
The prospectus also lists unusually broad risks, including constrained access to computing power, intense competition, cyber and biological misuse, government restrictions, and the possibility that advanced systems could escape effective control. Those disclosures are risk statements rather than predictions. They matter because Anthropic’s pitch combines aggressive commercial growth with a public identity built around AI safety, leaving investors to assess whether those goals reinforce or strain each other.
