Anthropic seeks $100 billion in record Nasdaq debut

Anthropic filed for an initial public offering on Monday, targeting a raise of up to $100 billion. The San Francisco company aims to list on the Nasdaq Global Select Market under the ticker symbol ANT. This move would make it the largest stock sale in history if it reaches that figure.

The filing positions the company for a Wall Street debut next month. It would eclipse the $86 billion raised by SpaceX in June. Anthropic would also go public before its rival OpenAI, which is expected to follow with its own major stock offering. The two rival AI labs are set to lead a pair of blockbuster debuts.

CEO Dario Amodei recently argued in an essay that the development of advanced AI models should be slowed. He warned that these systems could pose an existential threat to humanity. This caution comes as the company seeks billions in new capital to accelerate its expansion.

The 335-page filing reveals that Anthropic has not yet turned a profit. The maker of the chatbot Claude reported a net loss of $80.7 billion in the first half of 2026. This figure is a sharp increase from the $13 billion loss reported in the same period a year earlier.

Private investors valued the company at $965 billion earlier this year. Reports suggest the IPO could push that value to $1.5 trillion or possibly $2 trillion. At $1.5 trillion, Anthropic would rank among the world's most valuable public companies, sitting alongside Tesla. The final valuation and offering price remain undetermined.

The company was founded by Dario Amodei and his sister, Daniela. A successful offering could boost their personal wealth by billions of dollars. The five-year-old startup is now one of the most valuable private technology firms in the world.

The filing confirms the company's rapid revenue growth. It also discloses the scale of its operational costs. The document provides the first detailed public look at the financials of the firm behind Claude.
