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 are 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.

As states grapple with how to regulate an industry developing at an unprecedented pace, Al Jazeera unpacks the companies driving the AI race and the trillions of dollars behind them.

Who is who in AI?

Chatbots and large language models are only the visible tip of the AI industry. Beneath them sits a much larger ecosystem of hardware, infrastructure, and software.

These companies can be broadly grouped into three categories:

Hardware

At the foundation of the AI industry are the companies that design and manufacture the physical chips AI runs on, along with the equipment that keeps data centres powered and cooled.

These include:

• Chip designers such as Nvidia, Marvell, AMD, Broadcom, and Intel.
• Chip makers like TSMC, which physically manufacture the designs.
• Infrastructure firms such as Arista Networks, Vertiv, and Eaton, which supply the power, cooling, and networking equipment data centres depend on.

Cloud and compute

These are the companies that turn raw chips into usable computing power, delivering the storage and processing capacity that AI systems run on.

These include:

Software and applications

These are the companies that create the AI products people and businesses actually use.
