Amazon is moving to challenge Nvidia’s dominance in the AI chip market by planning to sell its in-house AI chips, like Trainium, to other companies for data center use. With a potential $50 billion annual revenue run rate, Amazon’s chip business could become a major competitor, though Nvidia currently leads with a $326 billion revenue stream. The shift comes as demand for Amazon’s AI chips outpaces supply, raising questions about whether it can scale production to meet both internal and external needs.
