Facing US export controls, China's DeepSeek plans to make its own chips

China's DeepSeek and other domestic AI companies are accelerating custom chip development for data center inference to circumvent US export controls and reduce dependency on Nvidia, a strategic trend mirrored by US-based AI leaders like OpenAI and Anthropic pursuing similar vertical integration. This fragmentation of the AI chip ecosystem signals a shift toward regional technology sovereignty and creates supply chain diversification pressures for enterprises, potentially fragmenting global AI infrastructure standards and increasing complexity for IT organizations managing multi-cloud and hybrid AI deployments. CIOs should anticipate growing chip availability constraints, regional technology stack divergence, and the need to evaluate vendor lock-in risks across both US and non-US AI service providers.
