Anthropic files for IPO: 7 key numbers from its S-1 filing

Anthropic filed its S-1 registration document on Monday, October 26, 2026, revealing first-half 2026 revenue of $16.29 billion, up from $1.16 billion a year earlier, and plans to list Class A shares on Nasdaq under the ticker "ANT." The filing shows $1.0 billion in Q2 operating profit on $11.6 billion revenue, though the first half recorded a $693 million operating loss. A headline net loss of $80.75 billion largely stems from a $72.39 billion non-cash fair-value adjustment tied to rising valuations, not operational spending. Anthropic holds $131.65 billion in cash and short-term investments, with about 5,300 employees and over 11,900 clients generating $100,000 or more in annual revenue. Founders will control 50.1% of voting rights via Class F shares, making it a "controlled company" under Nasdaq rules.
