Artificial intelligence company Anthropic filed papers Monday for what could be the largest initial public offering of stock on record. The San Francisco company plans to list its shares on the Nasdaq Global Select Market under the ticker “ANT,” with a Wall Street debut expected next month.
The 335-page filing showed revenue growing quickly, but the company has not turned a profit. It reported a net loss of $80.7 billion in the first half of 2026, compared with a $13 billion loss in the same period a year earlier. Private investors valued the company at $965 billion earlier this year, and reports suggest the public valuation could reach $1.5 trillion or more. The offering could raise as much as $100 billion, according to reports, which would top the $86 billion SpaceX raised in June.
The filing also lists risks, including the possibility that its AI models “pose catastrophic or existential risks to humanity.” That warning comes from a company whose CEO, Dario Amodei, argued in September for slowing the development of advanced models. He and his sister, Daniela, the company’s president, could each see fortunes of billions of dollars.
Anthropic has also been in a legal fight with the U.S. government since February, when the Trump administration designated the company a supply chain risk. The company sued the Pentagon in March. Rulings so far have gone both ways, and both sides are appealing.
