Anthropic overtakes OpenAI in valuation battle, becomes world’s most valuable AI startup

Anthropic has overtaken OpenAI to become the world’s most valuable AI startup, with a $965 billion valuation following a $65 billion Series H funding round. The San Francisco-based company, founded in 2021 by former OpenAI researchers including Dario Amodei, attributed the surge to strong demand for its Claude chatbot and enterprise AI tools, as businesses prioritize generative AI integration. The funding round included contributions from Altimeter Capital, Dragoneer, Sequoia Capital, and strategic partners like Amazon, Samsung, and Micron Technology. Amazon alone committed $5 billion, highlighting the growing reliance on cloud infrastructure for AI development. Anthropic plans to use the funds to expand computing capacity, advance AI safety research, and scale its Claude product suite amid record demand. Anthropic disclosed its annual revenue run rate has surpassed $47 billion, driven primarily by enterprise adoption of its AI coding tools, Claude Code. The company has faced capacity constraints due to rapid growth, underscoring the strain on compute infrastructure as AI adoption accelerates across industries. The valuation shift intensifies competition between Anthropic and OpenAI, both of which are reportedly preparing for potential public listings. While OpenAI’s ChatGPT sparked the generative AI boom in 2022, Anthropic’s rapid rise reflects a broader industry shift toward competing platforms. Strategic partnerships with chipmakers and cloud providers are now critical to securing the computing power needed for next-generation AI models. Industry analysts suggest both companies are positioning for historic IPOs, with investor pressure mounting as valuations approach unprecedented levels. The funding round signals a new phase in the AI industry, where access to semiconductors and compute infrastructure is as vital as model innovation itself.
