Anthropic Files for IPO With $80.7B Valuation

Anthropic filed its S-1 with the SEC on Monday, ending weeks of leaks and setting up a listing under the ticker "ANT." The paperwork confirms what had circulated for weeks but adds hard numbers: revenue of $16.3 billion for the first half of 2026, up from $1.2 billion over the same stretch in 2025. Operating losses narrowed to $693 million from $2.1 billion a year earlier, a sign the business is moving toward something closer to sustainable. Then there's the net loss, $80.7 billion, a figure tied to noncash accounting adjustments on convertible debt rather than cash burn. Anthropic says in the filing it "may not achieve or sustain profitability in the future."

The document also spells out how big the enterprise side of the business has gotten. By the end of September, more than 11,900 customers were spending at least $100,000 a year with Anthropic, 1,900 were spending $1 million or more, and roughly 250 had crossed the $10 million mark. The filing also lays out who will actually run the company once it's public, and how much control the seven co-founders intend to keep.
