The United States' rapid expansion of AI data centers is encountering significant supply chain risks due to heavy reliance on Chinese-manufactured equipment, including transformers, batteries, and optical transceivers [1]. As U.S. hyperscalers invest billions in new data center infrastructure to support AI development, analysts highlight that Chinese firms supply large portions of the critical components required for these facilities [1]. This dependency is drawing increased scrutiny from Washington, especially as tensions with Beijing escalate over AI supremacy and national security concerns [1].
Last week, President Donald Trump signed an executive order declaring a national emergency regarding the 'extraordinary foreign threat' posed by foreign-produced bulk-power system equipment, authorizing the Energy Department to prohibit or impose conditions on certain transactions involving components used in the grid and data centers [1]. Analysts warn that U.S. and Western suppliers may struggle to quickly replace Chinese manufacturing capacity, which could result in higher costs or exacerbate supply chain shortages for the ongoing AI infrastructure buildout [1].
Industry experts note that the focus of scrutiny has shifted from the compute stack to the power stack of data centers, which is essential for maintaining minimal downtime [1]. Key areas of dependency include substation transformers, switchgear, and batteries, with China's share of certain transformer and switchgear categories running near 30% [1]. This strategic vulnerability is considered significant as the adoption of advanced Chinese AI models grows globally, even though American companies still produce the most advanced chips and hardware for AI [1].
Analysts from The Economist Group and Wood Mackenzie, as well as academic experts, emphasize that the mid-term exposure is concentrated in grid connectors and that the U.S. AI data center ambitions could face substantial challenges if supply chain disruptions occur or if regulatory actions restrict access to Chinese components [1].
CONCLUSION
The U.S. AI data center boom is at risk due to its reliance on Chinese-made power equipment, which has become a focal point for national security and supply chain concerns. With new regulatory scrutiny and the potential for higher costs or shortages, the market faces significant uncertainty as it seeks to balance rapid AI infrastructure growth with geopolitical and supply chain vulnerabilities.
