Key Facts
- Anthropic announced the funding round Thursday, revealing a $965 billion post-money valuation involving investments from Altimeter Capital, Dragoneer, Greenoaks and Sequoia Capital.
- OpenAI raised $122 billion in a March funding round that increased its valuation to $730 billion, or $852 billion post-money.
- Anthropic has more than doubled the valuation it posted in its previous funding round in February, when it raised $30 billion for a $380 billion valuation.
- Anthropic said in its statement it expects its new funding to improve its safety research and help increase the computing power needed for growing demand of Claude, its flagship AI model.
Surprising Fact
OpenAI’s ChatGPThas dipped in dominance after becoming the fastest-growing consumer app more than three years ago. The ChatGPT app has accounted for 47% of global AI app downloads in the second quarter of 2026 so far, SensorTower told Forbes, marking a reduction from the 67% of all AI app downloads it accounted for in the same period last year. Anthropic’s Claude makes up 14% of AI app downloads so far in the second quarter of 2026, a dramatic increase from the 1% it accounted for in each quarter last year.
Key Background
Anthropic has raised over $130 billion since it was founded in 2021 by a group of former OpenAI executives including siblings Dario Amodei and Daniela Amodei, who both have an estimated net worth of $7 billion. Anthropic said its revenue run rate, a metric used to estimate a company’s full-year revenue, crossed $47 billion this month. The company recently struck an agreement with Elon Musk’s SpaceX to use the company’s “Colossus” supercomputer to “directly improve capacity for Claude Pro and Claude Max subscribers.” As it has grown larger, Anthropic has also found itself in the middle of a major government dispute after refusing to give unrestricted access to its AI models, citing concerns over government-sponsored mass surveillance and automated weapon development. The Pentagon later declared Anthropic a national security supply chain risk, a designation the company is fighting in court.
