Anthropic files for IPO with founder control
Anthropic filed for an initial public offering and disclosed strong first-half revenue growth, large losses tied to accounting adjustments, and a governance setup that would leave control with its founders and trust structure.
- Anthropic filed for an initial public offering on Monday and said it planned to list under the ticker ANT.
- The company reported revenue of $16.3 billion for the first half of 2026, up from $1.2 billion a year earlier.
- It reported an operating loss of $693 million and a net loss of $80.7 billion, which it said was largely caused by non-cash accounting adjustments tied to convertible debt.
- As of the end of September, Anthropic said it had more than 11,900 customers spending at least $100,000 a year, 1,900 spending at least $1 million and about 250 spending at least $10 million.
- The filing said seven co-founders would form the Founder LLC, which would control 50.1% of shareholder voting power, while the Long-Term Benefit Trust would appoint most of the board.
Anthropic filed for an initial public offering on Monday after weeks of leaked drafts. The company said it intended to list under the ticker ANT.
In its latest SEC filing, Anthropic said first-half revenue in 2026 reached $16.3 billion, compared with $1.2 billion in the same period of 2025. It also said operating losses narrowed to $693 million from $2.1 billion a year earlier.
The company said its net loss was $80.7 billion, mainly because of non-cash accounting adjustments linked to convertible debt. It also said it might not be able to achieve or keep profitability.
Anthropic said that, at the end of September, it had more than 11,900 customers spending $100,000 or more each year, 1,900 spending $1 million or more, and about 250 spending $10 million or more.
The filing said Dario Amodei, Daniela Amodei, Tom Brown, Jack Clark, Jared Kaplan, Sam McCandlish and Christopher Olah would make up the Founder LLC. That group would control 50.1% of shareholder voting power, and the Long-Term Benefit Trust would have authority to appoint most of the board.
