Anthropic heads for the market with $16.3 billion in revenue and founder control

Anthropic published its S-1 registration statement on October 26 for a planned Nasdaq IPO under the symbol ANT. The number of shares and price range remain blank. The prospectus nevertheless brings the company's financial growth, costs and unusual governance into one investor document for the first time.

The S-1 reveals $16.3 billion of revenue in six months

Anthropic reported $16.286 billion of revenue for the first 6 months of 2026, up from $1.163 billion in the same period of 2025. The number of customers generating at least $100,000 of annualised revenue for Anthropic rose from more than 600 to more than 6,000, according to the filing.

The headline net loss of $80.748 billion needs context. The operating loss for the half was $693 million. Most of the gap came from a non-cash $72.388 billion change in the fair value of convertible notes, derivatives and SAFEs, driven by the company's rising valuation. The net loss is therefore not a measure of cash consumed by operations.

Public investors get shares while founders keep the wheel

Immediately before the offering, a single Class F share is due to be issued to Founder LLC. Its members will be the 7 co-founders, including Dario and Daniela Amodei. That class will carry 50.1% of voting power on general matters, including the election of directors other than Class T directors, but no economic rights.

The Long-Term Benefit Trust sits alongside it. Through Class T stock, it generally has authority to elect and remove the Class T directors who will form a majority of the authorised board. Anthropic consequently says it will qualify as a controlled company under Nasdaq rules. The IPO creates public capital and a market price, not conventional shareholder control.

The prospectus describes both the race and its bill

Revenue growth is extraordinary, as is the dependence on expensive infrastructure. Compute and infrastructure expenses reached $8.945 billion for the half, while total debt stood at $6.2 billion on June 30. The filing also warns that compute secured today can become economically or technically unattractive as the field advances.

This first public S-1 remains incomplete. Share count and price are missing, and the registration statement is not yet effective. The figures support analysis of the business, but not yet the offer valuation or likely return for a new investor.

The real control question will outlast the offer price

Later amendments will supply the price range, deal size and dilution. Investors should also watch how Founder LLC and the Long-Term Benefit Trust handle conflicts among growth, the safety mission and the interests of public shareholders.

Anthropic is arriving as both a fast-growing supplier and an experiment in governing a powerful AI company. Its first public results will show whether the unusual structure protects a long horizon or mainly shields leadership from the people supplying capital.

Lilith's verdict

Anthropic is inviting the public to the cashier while handing the wheel to 7 founders and a safety trust. Investors can buy a seat in the car, but they will not choose the route.
