Anthropic Surpasses OpenAI to Become the World's Most Valuable AI Startup

Anthropic has become the most valuable artificial intelligence startup in the world, overtaking OpenAI in market valuation. After a new funding round, the value of the company behind the Claude assistant has approached the $1 trillion mark.

A $65 billion Series H round

Anthropic said it raised $65 billion in a Series H round. The largest investors included Altimeter Capital, Dragoneer, Greenoaks and Sequoia Capital. The package also took in previously agreed investments, among them $5 billion from Amazon.

The new valuation is nearly three times higher than the company's February estimate of roughly $380 billion. That places Anthropic ahead of every other private AI company in Silicon Valley.

Claude Code and the revenue curve

The main driver of the growth is said to be the popularity of the Claude assistant and the Claude Code service, which is widely used by software developers. Anthropic reported that its annual revenue has reached $47 billion; a year earlier the figure stood at about $10 billion.

Alongside the funding news, the company introduced the Claude Opus 4.8 model and Claude Mythos Preview, a closed system that offers enhanced cybersecurity capabilities for corporate clients. Chief Financial Officer Krishna Rao said demand for Claude products keeps growing rapidly around the world.

The IPO race

Anthropic's rise has intensified competition in the AI market. In March, OpenAI was valued at $852 billion after a record $122 billion funding round. Both companies are now preparing for public listings: according to CNBC, OpenAI may file for an initial public offering within the coming weeks, while Anthropic is also considering a stock offering, though the timing has not been disclosed.
