In 2026, the balance of power in the AI industry has shifted. Anthropic, the company behind Claude, now reports an annualized rate of revenue (ARR) of $47 billion — surpassing OpenAI, which itself reported an annualized rate of between $25 and $33 billion. Just a year ago, Anthropic's ARR was roughly $10 billion.
Claude Code is the engine
The single biggest explanation behind the growth is Claude Code, Anthropic's AI-powered coding assistant. Companies have quickly started paying for agent-based coding tools that actually deliver finished, executable code — not just suggestions in a chat box. Anthropic has also passed OpenAI in share of enterprise subscriptions, while in May 2026 ChatGPT dropped below 50 percent of monthly visits in the generative AI market for the first time.
The valuation is included
The growth has left an impression on the valuation side as well. A $65 billion Series H round recently valued Anthropic at just under $1 trillion — higher than OpenAI, long seen as the undisputed number one.
What does this mean for you who buy AI tools?
The shift is a reminder of how quickly conditions change for those who build their business on a single AI tool. Two years ago, ChatGPT was the default choice for most companies. Today, the picture is more fragmented, and those who tie themselves tightly to a single supplier run the risk of having to rebuild their workspace when price tags, models or market leaders change places. It is also the very basic idea behind open standards such as MCP (Model Context Protocol) — to be able to change the AI engine without having to rebuild one's entire platform.
OpenAI strikes back
OpenAI is far from out of the game. During the summer, Sam Altman spoke of a "new world order" for AI, and the company continues to invest heavily in infrastructure and new models to defend its position against both Anthropic and Google. But for the first time in a long time, it is not OpenAI that sets the pace in all measurements.
