Anthropic is taking Claude public. The company has filed for an initial public offering under the proposed ticker ANT, turning one of the AI industry’s most closely watched private companies into a public-market test case.
The filing matters because it makes Anthropic’s scale visible, while also exposing the unusual structure it wants to carry into public ownership. Anthropic generated $16.3 billion in revenue during the first half of 2026, up from $1.2 billion in the same period last year. It still recorded an operating loss of $693 million, although that was an improvement on the $2.1 billion operating loss reported for the first half of 2025.
Anthropic’s growth is already enterprise-scale
The filing shows that Anthropic is not approaching the market as a consumer AI experiment looking for a business model. It reportedly had more than 11,900 customers spending at least $100,000 annually by the end of September. Around 1,900 customers spent $1 million or more, while roughly 250 spent at least $10 million.
Those figures place Claude inside large-company workflows, where the question is less whether people will try AI and more whether companies will keep paying for it at scale. The numbers also help explain why the public debut will be watched by marketers, technology buyers and investors beyond the usual AI circle.
The financial picture is less tidy. Anthropic reported an $80.7 billion net loss, largely driven by noncash accounting adjustments connected to convertible debt. The company also warned that it may not achieve or sustain profitability, a reminder that rapid AI revenue growth still comes with unusually heavy infrastructure and financing demands.
Going public does not mean giving up control
Anthropic’s governance model may prove more consequential than its ticker. Its seven co-founders are expected to form a Founder LLC that will control 50.1% of shareholder voting power, according to the report. Anthropic says the structure is intended to protect its AI safety mission.
The company’s Long-Term Benefit Trust, established in 2023, will also have the authority to appoint most of the board. That gives Anthropic a public-market path without fully adopting the idea that shareholder voting power should track economic ownership.
For investors, the trade-off is clear. They may gain access to one of the fastest-growing AI businesses, but they will have limited practical influence over a company that acknowledges its technology could pose catastrophic or existential risks. Anthropic’s IPO is therefore not only a test of AI economics. It is a test of whether public markets will accept concentrated control as the price of preserving a company’s stated mission.
