Artificial intelligence used to be a novelty a decade or two ago. But now AI is at the center of the universe. From chatbots to recommendation systems, AI has penetrated deep into the corporate world. There are some areas where AI is taking over from humans, such as in coding assistants, enterprise systems, national defense, drug discovery, and more.

The US is in the lead in the race for AI dominance, and no one disagrees about that. US-based companies produce the foundation models, silicon, and cloud infrastructure that enable all other AI activity outside of China. But that doesn’t mean that these companies are giants. 

The companies have turned from obscure start-ups with a few thousand dollars to giant conglomerates with hundreds of billions of dollars in value and tens of billions in revenue, providing services to billions of users. There are many AI companies in the US, spanning foundation model research, cloud infrastructure, silicon fabrication, and enterprise software.

These are the 10 largest AI companies in the US in terms of valuation, influence, and disruption. The article covers the 10 most popular AI companies in the US and provides information about their founding year, ownership structure, overview, and services.
