Anthropic, the artificial intelligence company behind the Claude models, filed its S-1 registration statement with the U.S. Securities and Exchange Commission on October 26, advancing plans for a Nasdaq listing under the ticker symbol ANT. The filing pairs surging revenue with an $80.7 billion net loss for the first half of 2026, most of which stems from noncash accounting charges rather than operating spending.
An S-1 is the registration document U.S. securities law requires before a company can market shares to the public, and filing one opens a review period in which the SEC can request revisions before terms are set. The proposed offering could raise as much as $100 billion and value Anthropic between $1.5 trillion and $2 trillion, according to reported estimates. The fundraising figure remains unconfirmed: neither number is established in the filing, and the Nasdaq offering carries no disclosed share count or price — details that customarily surface in amended filings as a listing approaches.
The filing was quickly confirmed by market commentary account The Kobeissi Letter:

Goldman Sachs and Morgan Stanley are leading the offering. A Nasdaq debut during the week of November 16 remains a reported target rather than a confirmed timetable — a distinction that matters as investors assess the gap between headline losses and actual operating performance.
$80.7 Billion Loss Includes $72.4 Billion in Noncash Charges
Anthropic generated $16.3 billion in revenue during the first half of 2026, compared with approximately $1.2 billion in the same period a year earlier. Over the same periods, its net loss jumped from $13 billion to $80.7 billion.
About $72.4 billion of that deficit reflected noncash revaluations of convertible notes and related instruments, tied mainly to rising company valuations. Those accounting charges explain most of the headline number without representing equivalent cash spent on operations.
The underlying operating loss narrowed to $693 million from $2.14 billion, even as computing and infrastructure costs reached approximately $8.95 billion. By September 30, more than 11,900 customers each generated at least $100,000 in trailing annual revenue, according to the filing.
For prospective Nasdaq shareholders, that contrast is central: fast-growing enterprise demand comes alongside expensive infrastructure needs and an enormous accounting loss. The disclosures also carry weight beyond Anthropic itself: because the company's financials were previously private, the S-1 gives outside observers their most detailed public look to date at the revenue, compute costs and customer concentration behind a frontier AI business.
Compute Deals and 50.1% Founder Control Shape the IPO
The filing discloses computing commitments of up to $120.5 billion involving SpaceXAI and Nvidia, alongside $114.5 billion with Google through 2033. Meanwhile, Amazon agreements involve at least $110 billion through 2036, with additional equipment leasing arrangements involving Broadcom.
These partnerships also influence revenue. Amazon and Google accounted for 47% of 2025 sales through their cloud marketplaces, while simultaneously serving as investors suppliers and competitors.
The long-term obligations contrast with usage-based customer payments, however, creating financing risks if growth slows. Anthropic warned that additional funding could become necessary sooner than expected, while cash dividends remain unlikely.
Beyond financing governance presents another consideration. The seven co-founders would retain 50.1% voting control, limiting outside shareholders' influence over major decisions. Meanwhile, a proposed Public Benefit Fund could receive 5% of shares, subject to approval.
Additionally, the filing highlights catastrophic AI risks, including manipulation, concealed information and resistance to shutdown. These disclosures place the prospective Nasdaq listing under scrutiny over spending commitments, governance and technological risks.
