Anthropic has made its IPO prospectus public, filing an S-1 on 26 October to list on Nasdaq under the ticker ANT. The filing confirms first-half 2026 revenue of $16.3 billion and shows its first quarterly operating profit, $974 million in the second quarter. Chip stocks rallied from New York to Seoul.
What the Anthropic S-1 filing confirms
In a short statement, Anthropic, PBC said it had filed a registration statement with the US Securities and Exchange Commission for a proposed IPO of Class A common stock on the Nasdaq Global Select Market. The number of shares and the price range “have not yet been determined”. Until now, outsiders relied on reports of the confidential draft, covered in our analysis of the draft S-1 figures. The public document on SEC EDGAR lets those numbers be checked.
- Revenue: $16,286 million in the six months to 30 June 2026, against $1,163 million a year earlier, according to the prospectus summary. Full-year 2025 revenue was $4,585 million, StockTitan notes from the filing.
- Losses: a first-half operating loss of $693 million, narrower than $2,135 million a year earlier, and a net loss of $80,748 million. About $72.4 billion of the net loss is a non-cash charge from the higher fair value of convertible notes and similar instruments, as both StockTitan and Techloy report.
- The turn to profit: second-quarter revenue was $11.6 billion and operating income $974 million, after a $1.7 billion operating loss in the first quarter, according to Yahoo Finance’s live coverage. Compute costs rose to $5.6 billion from $3.4 billion, much slower than revenue.
- Cash: cash, cash equivalents and short-term investments of $131.7 billion at 30 June, per the S-1 summary.
- Customers: more than 1,900 customers paid $1 million or more over the trailing twelve months to 30 September, and about 250 paid $10 million or more. The filing puts net revenue retention at about 900%.
Who controls Anthropic after the IPO
The share structure is the part of the filing that most limits what new investors can decide. Class A shares carry one vote each. A single Class T share, held by the Long-Term Benefit Trust, elects the directors who form a majority of the board. A single Class F share, held by a founders’ entity, carries 50.1% of the total voting power on general matters, including the remaining board seats. The S-1 says this makes Anthropic a “controlled company” under Nasdaq rules. Shares issuable to Amazon Web Services on conversion of its notes would be non-voting Class N shares.
Goldman Sachs and Morgan Stanley lead a syndicate of 22 banks, the filing shows. The lock-up is unusual. Under the schedule summarised by StockTitan, some directors, officers and employees may sell up to 10% of their holdings from the first trading day, with staged releases running out to a year for large holders and co-founders. Standard IPO lock-ups last 180 days.
Why the compute bill still matters
The prospectus leaves its aggregate commitment figure blank in the summary, so totals depend on who is adding. PPC Land and StockTitan list minimum commitments of at least $114.5 billion to Google through July 2033, $110 billion to Amazon through April 2036 and $44.9 billion to Microsoft through May 2033. There are also about $161.2 billion of Broadcom equipment leases and up to $120.5 billion with SpaceXAI (see our report on SpaceX’s Q3 results). Yahoo Finance says the SpaceXAI arrangement runs through 2029, costing about $3.1 billion a month once capacity is fully delivered. StockTitan reports that either side can end that contract on 90 days’ notice after early 2027.
StockTitan reports that the cloud marketplaces of Amazon, Google and Microsoft accounted for about 48% of first-half revenue, and that the top five customers made up about a quarter of revenue in the first nine months. No single customer exceeded 10% in that period.
Market reaction: chip stocks rally in Asia
Wall Street rose on Monday. The S&P 500 gained 0.70% to 7,676.77 and the Nasdaq Composite 0.83%, with technology shares leading after the filing, HDFC Sky reported. The rally spread to Asia on Tuesday. South Korea’s KOSPI was up 3.72% at 5,672.96 by 9:30 a.m., with Samsung Electronics up more than 5% and SK Hynix more than 6%, SBS reported. TradingKey put the KOSPI’s intraday gain above 4% and the Nikkei 225 up 1.9%, with SoftBank and Kioxia also higher. It also cited an oversold rebound. These are intraday figures, not closes.
The India angle
For Indian markets, the effect runs mainly through global risk appetite and AI-linked flows. HDFC Sky noted that foreign portfolio investors sold Indian shares worth ₹1,462 crore on Monday, with crude near $115 a barrel keeping sentiment cautious. A large AI listing competes for the same global growth capital that funds Indian technology stocks. Its reception will also shape how investors judge enterprise AI spending, which matters for Indian IT services firms, as the Infosys guidance cut showed.
Who is more or less exposed
- More exposed: chip suppliers priced for AI demand, GPU-rental firms reliant on a few AI labs, and funds that bought pre-IPO exposure at high valuations.
- Less exposed: diversified hyperscalers and enterprise users with several model providers.
Scenarios to watch
These are conditional scenarios, not predictions.
| If… | Then a possible consequence would be… |
|---|---|
| The price range implies a valuation near the $1.5 trillion to $2 trillion range cited in press reports | The listing could become one of the largest ever by valuation, and index-inclusion questions could follow quickly |
| Third-quarter figures added to the filing show continued operating profit | Attention could shift from losses to the timing of compute payments |
| Early lock-up releases bring heavy insider selling | The shares could face supply pressure in the first weeks of trading |
| Demand disappoints or the timetable slips | AI-linked chip stocks in the US, Korea and Japan could give back recent gains |
What to watch next
- An amended S-1 with the price range and share count. Techloy, citing Fortune, says a listing is expected around Thanksgiving week, starting 23 November.
- The roadshow, which under SEC practice can begin 15 days after the public filing.
- SK Hynix’s results on 28 October, and quarterly results from Alphabet, Microsoft and Amazon this week, which will show how much AI demand cloud providers are seeing.
Bottom line
The public Anthropic S-1 confirms the scale of revenue growth reported from the draft and adds a first operating profit. It also sets out a governance structure that leaves public shareholders with limited control. The price range will be the next test of how much investors will pay for that combination.
Method note: This analysis compared Anthropic’s own filing announcement and the S-1 prospectus on SEC EDGAR with reporting and summaries by Yahoo Finance, StockTitan, Techloy, PPC Land, HDFC Sky, SBS and TradingKey. Compute totals are outside parties’ sums, because the filing’s summary leaves the aggregate blank. FutureKnowledge’s research tool is built on a model made by Anthropic; all figures here are attributed to the filing or to independent reports.
