What are the world’s biggest AI companies and how much are they worth?
From Nvidia and OpenAI to Anthropic and xAI, we break down the companies driving the AI boom and how much they're worth.

A renewed debate has emerged over who should control the development of artificial intelligence (AI).
The latest dispute follows an essay by Anthropic CEO Dario Amodei, who has argued that the development of increasingly powerful AI systems needs to slow down, calling for greater regulation.
US President Donald Trump pushed back, writing on Truth Social that the US already has “tremendous CRIMINAL and REGULATORY power” over AI companies, framing safety concerns as a conspiracy that only benefits China. He went on to say that whoever wins the AI race wins outright.
That’s bigger than the gross domestic product (GDP) of every country except the United States, and larger than the entire Chinese economy.
