AI Firm Anthropic Files for Stock Market Debut with Ticker ANT

Artificial intelligence company Anthropic filed papers on Monday to list its stock on the Nasdaq Global Select Market under the ticker symbol ANT. The San Francisco startup is preparing for a Wall Street debut next month that could potentially exceed the $86 billion record set by SpaceX in June. The public offering might raise up to $100 billion, which could push the five-year-old firm's market valuation to between $1.5 trillion and $2 trillion.

Financials and Risks

The 335-page regulatory filing reveals that while Anthropic's revenue is growing fast, the company is not yet profitable. The maker of the Claude chatbot reported a net loss of $80.7 billion in the first half of 2026, compared to a $13 billion loss in the same period last year. Private investors valued the company at $965 billion earlier this year. The offering documents also outline multiple business risks, including difficulties in keeping key staff, dealing with regulatory hurdles, securing enough compute power, and a warning that advanced artificial intelligence systems could pose existential or catastrophic risks to humanity.

Leadership and Context

Formed in 2021 by former OpenAI leaders, Anthropic was co-founded by CEO Dario Amodei and his sister Daniela. The upcoming stock debut puts Anthropic ahead of rival OpenAI in going public. Amodei recently published an essay urging the tech industry to slow down the development of advanced models to allow safety measures to catch up.

Context

Initial public offerings allow private companies to raise large amounts of capital by selling shares to the public stock market for the first time. Major tech firms often report large financial losses while prioritizing rapid expansion and infrastructure investments over short-term profits. Major stock market debuts like this one draw intense investor interest due to the rapid growth of the artificial intelligence sector.
