Anthropic, the AI firm led by CEO Dario Amodei, has raised $30 billion in a new funding round, boosting the company's valuation to $380 billion. This has nearly doubled the fortunes of Anthropic's seven billionaire cofounders, including Amodei and his sister Daniela Amodei, who are now each worth an estimated $7 billion. The fundraise comes as Anthropic has become a fierce competitor to rival OpenAI, with its enterprise-focused products like the Claude chatbot gaining traction.

Why it matters

The rapid growth of Anthropic and the wealth accumulation of its cofounders highlights the intensifying AI arms race, as well as concerns around wealth concentration in the tech industry. Anthropic's focus on responsible AI deployment also raises questions about the broader societal impact of these powerful AI technologies.

What they’re saying

“I definitely think they do a good job on this one singular focus of 'we're gonna get the enterprise right.' They have a good coding model for sure. I respect it a lot. I think that was a good innovation from them.”

— Sam Altman, CEO, OpenAI (Forbes)

“I guess it's on brand for Anthropic doublespeak to use a deceptive ad to critique theoretical deceptive ads that aren't real. Anthropic serves an expensive product to rich people. We are glad they do that and we are doing that too, but we also feel strongly that we need to bring AI to billions of people who can't pay for subscriptions.”

— Sam Altman, CEO, OpenAI (X)

“Your AI hates Whites & Asians, especially Chinese, heterosexuals and men...This is misanthropic and evil. Fix it.”

— Elon Musk (X)
