Anthropic targets mid-October IPO with governance structure and revenue transparency under investor scrutiny

Sep 5, 2026

Anthropic is delaying its highly anticipated IPO, shifting its marketing launch to mid-October 2026 with a target listing just before the November US midterm elections. The AI giant is eyeing a public valuation near $2 trillion, up from its $965 billion private valuation in May. While Anthropic posted its first quarterly operating profit of $559 million on $11.5 billion in Q2 revenue, prospective investors are demanding transparency on how the company accounts for revenue from cloud resellers like Amazon and Google.
