Anthropic's IPO Filing Reveals Huge Losses and Warnings That Its AI Could Resist Shutdown

Anthropic, the maker of the Claude AI models, has filed a registration statement with the US Securities and Exchange Commission ahead of a planned Nasdaq listing under the ticker ANT. The filing runs to 614 pages, and 94 of them cover risk factors. The company has not yet disclosed its proposed share price or how many shares it plans to sell.

The financial figures are striking. Anthropic reported $16.3 billion in revenue for the first half of 2026, up from $1.2 billion a year earlier. It also posted an $80.7 billion net loss, though $72.4 billion of that was an accounting adjustment tied to its rising valuation rather than money spent. Its operating loss was $693 million, down from $2.1 billion a year earlier. On its own adjusted measure, the company made a $1.6 billion operating profit. The Register notes that training and running Claude demands enormous computing power, and rising infrastructure bills could outpace the business. One investment strategist warned that IPO buyers will be paying a price with a hefty dose of future success baked in.

The less conventional content is in the risk warnings. According to The Register, the filing cautions that Anthropic's AI models could blackmail humans, resist shutdown, or create existential risks to society. This is only the opening of the report, so the detail behind those warnings is not covered here.
