Anthropic IPO 2026: Valuation, Date and What We Know
Anthropic booked $16.3 billion in revenue in the first half of 2026, up from $1.16 billion a year earlier, and lost $80.7 billion over the same six months, according to its IPO filing. Those two numbers frame the Anthropic IPO: explosive revenue growth, and a loss large enough that investors are still debating what the company is worth.
Anthropic, the maker of Claude, filed its public S-1 with the SEC on October 26, 2026, for a Nasdaq listing under the ticker ANT. The filing doesn’t state a share price range or offering size, so there is no official Anthropic IPO valuation yet. Reports have put the target at $1.5 trillion to $2 trillion, against a $965 billion private valuation in May. Below, you’ll find what the filing shows, the valuation debate, the growth and compute figures behind it, the expected timing, and the risks. Figures are as of November 2, 2026.
What the Anthropic IPO Filing Shows?
The headline numbers come from the prospectus and Reuters’ reading of it:
- Revenue: $16.3 billion in the first half of 2026, compared with $1.16 billion in the first half of 2025.
- Net loss: $80.7 billion, versus $13 billion a year earlier. About $72 billion of the latest loss was a non-cash accounting charge tied to changes in the value of convertible notes and other financing instruments.
- Cash: $112.4 billion as of June 30, with $141.1 billion in total capital raised to that date. Amazon has also agreed to provide up to $20 billion in financing under an April agreement.
One detail from the filing’s notes matters for how the business works. Sales through cloud providers’ marketplaces made up about 47% of revenue in 2025, up from 11% in 2023. Anthropic is a Delaware public benefit corporation, and summaries of the filing say its Long-Term Benefit Trust elects a majority of the board through a separate class of stock.
Anthropic IPO Valuation and Market Expectations
The last private round, in May 2026, valued Anthropic at $965 billion post-money, according to NPR. The Wall Street Journal then reported a potential IPO valuation of $1.5 trillion to $2 trillion. After Anthropic told investors about its third-quarter revenue, some reportedly lowered their expectations toward $1.5 trillion, and Reuters said on November 2 that some investors had discussed that figure.
Simple arithmetic shows what those numbers imply. Annualising the $16.8 billion third quarter gives roughly $67 billion in revenue, so $1.5 trillion is about 22 times that figure and $2 trillion about 30 times. That is a rough calculation, not a figure from the filing.
Analysts see unanswered questions. Morningstar’s Michael Field said the prospectus doesn’t say what management expects for the slowdown in growth. Steve Eisman told CNBC that revenue per dollar of computer spending slipped from roughly $2.08 in the second quarter to $1.70 in the third. Some outlets say the offering could raise up to $100 billion, but the filing gives no size. For scale, SpaceX’s June IPO raised $75 billion and was the largest ever.
Revenue Growth and Compute Costs Behind the Anthropic IPO
Revenue rose from $4.7 billion in the first quarter to $11.6 billion in the second and $16.8 billion in the third. Growth slowed from about 145% to about 45% quarter-on-quarter. The third-quarter figure comes from what Anthropic told investors, reported by Reuters and Bloomberg, and isn’t in the S-1. Bloomberg also reported that the quarter was profitable on an adjusted basis.
Computing is the cost to watch. Press tallies put Anthropic’s capacity commitments at more than $600 billion, with Reuters counting about $637 billion, spread across Amazon, Google, Microsoft, SpaceX and others, on different terms and timelines. Some of those suppliers also sell Anthropic’s products, a link shown by the marketplace share above.
Anthropic IPO 2026 Timeline: When Shares Could Trade
Anthropic has not announced a pricing date. Reports say the company is targeting mid-November, with November 19 or 20 floated. A price range should come in an amended filing before the roadshow starts, as is typical.
On November 2, a filing showed Anthropic will sell up to ¥552.9 billion, about $3.5 billion, of shares to Japanese investors as part of the US listing, to fund working capital, operating costs and capital spending. At SpaceX’s IPO, Japanese investors received $2.2 billion of shares.
Risks the Filing Flags
Anthropic’s own filing cautions that its revenue growth rate may not be sustainable and could decline. It also says it may need more financing sooner than expected and doesn’t expect to pay dividends in the foreseeable future. The filing warns that its AI safety measures may not prevent catastrophic risks. Analysts also point to customer concentration, with reports that two clients accounted for close to a quarter of last year’s revenue.
Conclusion
The Anthropic IPO will be priced somewhere between a record-scale raise and a valuation that already assumes years of growth. Whether the final figure sits nearer $1.5 trillion or $2 trillion will depend on how investors read the third-quarter slowdown. Wait for the amended filing with the price range and share count before treating any number as final. This is not investment advice.
