Anthropic has filed for a public listing as revenue jumps to $16.3 billion. The maker of the Claude chatbot plans to list on Nasdaq under the ticker ANT, according to its filing with the United States securities regulator on Monday.
Revenue reached $16.3 billion in the first half of 2026, up from $1.2 billion in the same period a year earlier, the filing shows. Growth was concentrated in the second quarter, which alone brought in $11.6 billion, according to reports on the filing. The company has not yet said how many shares it will sell or at what price, so the final valuation remains open.
The filing also shows how far the business has spread among large customers. As of the end of September, more than 11,900 customers spent at least $100,000 a year with the company, while about 1,900 spent at least $1 million and about 250 spent at least $10 million, according to the filing.
A huge loss that is mostly accounting
The headline loss looks alarming at first glance. Anthropic reported a net loss of $80.7 billion for the first half of the year, but about $72.4 billion of that figure came from noncash accounting charges linked to convertible notes, according to reports on the filing. Those charges rose as the value of the company rose, rather than reflecting cash leaving the business.
The operating picture is far smaller. The operating loss narrowed to $693 million from $2.1 billion a year earlier, and the second quarter produced an operating profit of $974 million, the first such quarterly profit on that measure, according to reports. The core operation is moving closer to covering its costs.
Founders keep control, and that is the debate
Governance may prove just as important as the numbers. An entity owned by the seven founders will hold 50.1 percent of shareholder voting power after the listing, a structure the company says is designed to protect its public benefit mission. A separate long term benefit trust will have the power to appoint most of the board.
Critics argue that public shareholders will have little practical say over a company building technology it warns could pose serious risks. Supporters reply that insulation from short term market pressure is the point, letting the company hold to safety commitments. The debate echoes recent arguments about frontier labs and safety controls, where rapid gains have forced companies to rethink training and deployment.
The filing also marks a turning point for the wider artificial intelligence industry. Until now, the finances of the leading labs have been visible only in fragments. A public prospectus puts revenue, costs and computing commitments on the record, giving rivals, regulators and customers a common set of facts. Whether the market rewards that openness will shape how other frontier labs approach their own listings.
