Foxconn, Apple's largest manufacturing partner, announced a major alliance with OpenAI to design and build artificial intelligence data center hardware in the United States. The partnership aims to accelerate the development of AI infrastructure and secure a long-term domestic supply chain for essential components like servers, power, and cooling systems. Under the agreement, Foxconn will co-develop and manufacture the AI hardware at its U.S. facilities, and OpenAI will have early access to evaluate and potentially purchase the systems. The announcement comes as Foxconn plans to invest up to $3 billion annually in AI. This strategic shift by a key Apple supplier into the core of AI infrastructure highlights the technology's growing importance across the electronics ecosystem, though no direct market reaction for AAPL was noted.
