US AI Data Center Boom Faces China Supply Chain Risks
The article reports growing U.S. government scrutiny over reliance on Chinese components for AI data centers, including transformers, switchgear, batteries, and optical transceivers. President Trump signed an executive order declaring a national emergency on foreign bulk-power system equipment. Chinese firms supply roughly two-thirds of global optical transceiver units, and shortages in power transformers and substations are already acute. The article highlights investments by Nvidia in Lumentum and Coherent, each receiving $2 billion, and expansion plans by Hitachi Energy and Siemens Energy. Potential restrictions could raise costs and worsen supply chain issues for the AI buildout, which underpins digital advertising infrastructure.

China seeks share of U.S. AI data center boom
Chinese manufacturers and AI infrastructure companies are eyeing the U.S. data center buildout as a major opportunity, despite geopolitical tensions. The U.S. has 5,427 AI data centers compared to China's 449, according to Stanford. U.S. tech giants like Alphabet, Microsoft, Meta, and Amazon are expected to spend around $765 billion this year on AI infrastructure, potentially reaching $1 trillion next year. Chinese companies like Alibaba have committed less, but the Chinese government plans to invest $295 billion over five years. Singapore-registered Brightray, with its Chinese manufacturer PrefabDC, offers prefabricated data centers that can cut construction time by at least half. However, the Trump administration is considering bans on Chinese AI models and data center components due to security concerns. Analysts note that China remains crucial to the U.S. supply chain for components like transformers and fiber-optic cables.
China's AI Surge Challenges U.S. Tech Dominance
Analysts tell CNBC that China’s rapid progress in artificial intelligence is breaking the U.S.’s perceived technological monopoly and could reshape global tech supply chains. Rory Green of TS Lombard said a “China tech shock” is beginning as Beijing pairs large-scale tech development with lower production costs and large supply chains. China has launched a 60.06 billion yuan national AI fund and an “AI+” initiative to integrate AI across its economy. The report highlights Huawei’s deployment of large chip clusters and cheaper energy to scale compute, narrowing gaps with U.S. chip suppliers like Nvidia. Google DeepMind CEO Demis Hassabis said Chinese models may be only months behind Western rivals. The piece also notes heavy AI capital expenditure from U.S. hyperscalers and market concerns about returns.
10 Chinese Stocks Power U.S. Data Centers
A June 21 22V Research report, published with Analyst Hub Securities, highlights that many mainland China–listed companies supply key components for U.S. data centers and AI hardware. The U.S. relies on Chinese firms for roughly 30% of its imports of AI-related products, with China supplying ‘‘less sexy’’ but essential parts such as energy storage, transformers, critical minerals, chemicals, printed circuit boards, MLCC capacitors and optical/networking components. The ChiNext index has doubled over the past 12 months as hardware names drove gains. The report identifies ten large AI supply-chain companies (including CATL, Victory Giant, Dongshan Precision, Shengyi Technology, Sanhuan Group, Foxconn Industrial Internet, Sungrow Power, InnoLight, Eoptolink and TFC) whose market moves and capacity are important for investors and data‑center operators. JPMorgan analysts and others noted optics and fiber exports as a key channel for data‑center connectivity.
