Anthropic files for IPO that could value it at $2T, raise over $100B
What's the deal? Anthropic filed its S-1 with the US Securities and Exchange Commission on October 26, 2026, setting up what could be the largest initial public offering ever. The AI company plans to list its Class A common stock on the Nasdaq Global Select Market under the symbol "ANT," with Goldman SachsDealroom has a profile for this one. Try Dealroom → and Morgan Stanley leading the offering. Share count and pricing are not yet set, but the listing could value Anthropic at up to $2 trillion and raise more than $100 billion.
The numbers: Revenue hit $16.3 billion in the first half of 2026, up 14-fold year on year, after jumping from $41 million in 2023 to $4.6 billion in 2025. The company reported a net loss of $80.7 billion for the half — but roughly $72.4 billion was a non-cash charge from marking convertible notes to fair value as its valuation soared. Its operating loss narrowed to about $693 million, and it generated roughly $3.9 billion in positive operating cash flow.
Standout stat: Net revenue retention stood at around 900% as of September 30 — existing customers spending ninefold more year on year. The median public cloud software company sits at 108%. Anthropic now has more than 11,900 enterprise customers paying over $100,000 annually, up from about 950 a year earlier.
Who wins? Amazon is likely the single largest beneficiary. It holds convertible notes with $6.2 billion in principal outstanding, which its own filings valued at $97.9 billion as of June 30. Google is also set for a windfall. Venture backers including Menlo Ventures, Sequoia, Sound Ventures, and Spark Capital stand to return billions, though none owns 5% — a quirk of Anthropic's scale, where a 1% stake is worth nearly $10 billion at its $965 billion private valuation.
What could go wrong? Anthropic has committed up to $807 billion to data centre, chip, and computing contracts over 10 years, many of which cannot be cancelled. It warned it may need additional financing sooner than anticipated, even after the IPO. Its top five customers account for 25% of revenue, and the company itself cautioned that growth "may not be sustainable over time."
Why now? Anthropic is going public into a jittery market. AI data centre operator Firmus pulled its IPO this month, and SK HynixDealroom has a profile for this one. Try Dealroom → scrapped plans to list its SolidigmDealroom has a profile for this one. Try Dealroom → unit, both citing market conditions.
The signal: The filing offers the clearest picture yet of a frontier AI company's economics — explosive revenue, improving compute efficiency, and vast locked-in spending. It also sets a benchmark for rival OpenAI, whose own IPO is expected in 2027. The open question: whether any growth projection can justify a $2 trillion price tag.
