Anthropic Passes OpenAI With $900 Billion Valuation

Anthropic spent its early years known as the smaller AI lab next to OpenAI, and that gap just flipped in a single funding round.

The San Francisco company raised $65 billion at a $900 billion valuation, pushing it past OpenAI's last mark of $730 billion and making it the most valuable private AI company in the world.

That's a remarkable arc for a lab founded in 2021 by former OpenAI researchers, including siblings Dario and Daniela Amodei, who left over directional differences about AI safety and how the technology should be developed.

Coding Drove The Jump

Businesses are paying Anthropic to write their software, and that enterprise revenue is what powered the round.

The company's revenue run rate - the yearly pace of its current sales - crossed $47 billion this month, up sharply from $30 billion just a month ago.

The customer base behind that number has exploded, with hundreds of new businesses signing on since November, when Anthropic rolled out stronger coding tools backed by its new flagship model, Claude Opus 4.8.

The model is sharper at writing code from plain-English prompts, which means an engineer can describe what they want in a sentence and get working software back in seconds.

That kind of revenue comes from companies replacing engineering work with AI tools, not from free chatbots people use on their phones.

2.4x In 90 Days

Anthropic was worth $380 billion three months ago, which means the new round marks a nearly 2.4x jump in a single quarter.

The round was led by Greenoaks Capital, Sequoia Capital, Altimeter Capital, and Dragoneer Investment Group - all firms that backed Anthropic in earlier rounds and doubled down here.

For context, the $900 billion price tag would put Anthropic ahead of nearly every public company on the planet, behind only a small group of mega-caps like Apple, Microsoft, and Nvidia - and it's still private.

That gap with OpenAI also flipped fast, after OpenAI hit its $730 billion mark with most of the AI money flowing its way.

What To Watch

The AI race shifted from chatbots to code over the last 18 months, and Anthropic's raise shows where the money is following.

Whichever lab writes the most usable software for businesses tends to land the biggest checks, and right now that lab is Anthropic.

The next round of public AI numbers from Microsoft, Google, and Meta will show whether the coding boom is lifting the whole sector or just the labs selling directly to enterprise customers.

For now, every major AI lab is racing to land the next big enterprise contract, and the gap between winners and laggards is widening fast.
