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.
Highlights a notable US reliance (~30%) on Chinese suppliers for AI-related and data‑center components and identifies specific large suppliers and market-cap gains, which matters for infrastructure resilience, procurement and investor attention.

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.
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.
Cramer: Data Centers Drive Market's Biggest Winners
CNBC commentator Jim Cramer said the market can be viewed as two groups: data-center-related stocks and everything else. He argued that a broad buildout of AI infrastructure has pushed data-center exposure mainstream and is lifting companies across power, cooling, networking, semiconductors, industrial equipment and real-estate services. Cramer cited Quanta Services as an example for power/grid work, and named Eaton, Vertiv, Carrier Global, Teradyne, Qualcomm, Caterpillar, Ciena, Arista Networks, Cisco and Iron Mountain as beneficiaries. He suggested the recent strength may mark the start of a multi-year move tied to the expansion of data-center capacity.
