Anthropic, the San Francisco AI company behind Claude, publicly filed for an initial public offering on Monday and plans to list on the Nasdaq under the ticker "ANT," according to its SEC filing as reported by CNBC and NBC News.
Why it matters: The debut is expected to be one of the largest in market history. The Guardian said analysts and investors have valued the company at more than $1.5 trillion, and NBC News said the offering could value it at more than $2 trillion.
What the filing shows
- Revenue: $16.29 billion in the six months ended June 30, up from $1.16 billion a year earlier, CNBC reported. Revenue for all of 2025 was $4.59 billion.
- Losses: A net loss of $80.7 billion in the first half of 2026, after a loss of about $42 billion for all of 2025.
- Customers: No single customer made up more than 10% of revenue for the nine months ended Sept. 30, but five customers accounted for about a quarter of it, according to the prospectus.
- Banks: Goldman Sachs and Morgan Stanley are the lead underwriters.
Timing
Anthropic filed confidentially in June, CNBC reported. NBC News said the offering is widely expected sometime in mid-November. The company's last private round, in May, raised $65 billion at a $965 billion valuation, according to CNBC.
The filing lists risks including safety, reliable computing infrastructure and an "evolving, uncertain, and at times divergent global regulatory landscape," NBC News reported. The Guardian noted the company is challenging a federal designation as a supply chain risk that bars military agencies from contracting with it.
