Anthropic told investors this week that its preliminary revenue for the second quarter of 2026 exceeded $11.5 billion, up 14-fold from about $787 million in the same quarter of 2025 and more than double the $4.73 billion it reported for the first quarter, according to Bloomberg and CNBC reports dated August 15.
An Accelerating Enterprise Ramp
The results, described as preliminary and subject to change, would put Anthropic at roughly $16.2 billion in first-half revenue on a run-rate basis of well over $40 billion per year. Sources tell reporters the growth was driven by Claude on Amazon Bedrock and Vertex AI, enterprise coding tools including Claude Code, and expanded contracts with Fortune 500 rollouts that include agentic workflows and long-context knowledge worker deployments.
Adjusted Operating Income Turns Positive
Perhaps more strategically important than the revenue print, Anthropic told investors it posted positive adjusted operating income in the quarter. If confirmed at the audited-earnings level, that would make Anthropic the first frontier AI lab to publicly disclose operating profitability at scale — a milestone that OpenAI and other rivals have yet to claim as they burn tens of billions on training compute. Anthropic's inference-heavy revenue mix and disciplined compute contracts appear to be tilting unit economics faster than skeptics expected.
Fresh Fuel For IPO Speculation
The numbers land as Anthropic is reportedly in advanced talks for a fresh financing at a valuation approaching $170 billion, and as the market debates whether the company will file to go public in 2027. It also arrives alongside a flurry of AI dealmaking, from Stripe's $7 billion OpenRouter acquisition to Cerebras's 281% cloud revenue jump. Investors previously worried that generative AI economics would remain permanently negative; Anthropic's tape is now the sharpest counter-argument to that thesis.
Anthropic declined to comment on the specific figures. Audited quarterly results are not typically released by private companies, and the numbers may still be revised.
