Anthropic

Generative AI

Anthropic built its position by winning the enterprise market that OpenAI built its reputation on. The company now serves more than 300,000 business customers, and independent survey data credits Anthropic with roughly 40% of enterprise LLM API spend, the largest share of any single provider. Anthropic's annualized revenue run rate climbed from about $1 billion at the start of 2025 to more than $47 billion by May 2026, funded in part by a $65 billion Series H round.

Claude Code, launched in 2025, reached a $2.5 billion revenue run rate within a year, faster than any comparable enterprise software product in history, with named customers including Netflix, Spotify, and Salesforce. Claude also holds a distinct technical position: it runs as a supported model on all three major clouds, AWS Bedrock, Google Cloud Vertex AI, and Microsoft Azure Foundry, giving enterprise buyers a consistent option regardless of cloud strategy.
