U.S. export restrictions have handed China’s artificial-intelligence chip market to Huawei. Nvidia, once the dominant supplier of high-end AI processors to Chinese tech firms, has effectively surrendered that business to its domestic rival.
Why the export controls matter
Washington’s tightening rules bar Nvidia from selling its most advanced chips — like the A100 and H100 — to Chinese buyers. The company has tried to get around the limits with lower-spec versions, but those workarounds have been blocked or discouraged by regulators. The result: Chinese data centers and AI startups can no longer buy Nvidia’s top silicon.
Huawei, already under its own U.S. sanctions, saw an opening. The company’s Ascend series of AI chips has become the go-to alternative for Chinese customers who need powerful processors without running afoul of export law.
Huawei’s home-field advantage
Huawei doesn’t just supply hardware. It offers a full software stack, including development tools and a cloud platform, that makes it easier for Chinese engineers to build and run AI models. Nvidia’s CUDA ecosystem has long been the industry standard, but Huawei’s push for compatibility and local support is winning converts.
Chinese government procurement policies also favor domestic suppliers. State-owned enterprises and research institutes are under pressure to buy Chinese chips, which further shrinks Nvidia’s addressable market.
What Nvidia leaves behind
Nvidia still sells some chips in China — mostly older models and automotive parts. But the AI market, once its fastest-growing segment in the country, is now Huawei’s to lose. Analysts inside China say Huawei’s market share in AI accelerators jumped sharply in the past year. Exact numbers aren’t public, but the trend is clear.
Nvidia’s retreat is a win for Beijing’s push for self-reliance. The U.S. restrictions, intended to slow China’s military AI advances, have instead accelerated the rise of a homegrown competitor.
What happens next
The U.S. government shows no sign of loosening export controls. Nvidia has warned investors that lost China sales will hurt revenue for quarters to come. Huawei, meanwhile, is racing to boost production capacity for its Ascend chips, but it still faces its own supply-chain bottlenecks — especially for advanced manufacturing, which it sources from domestic foundries like SMIC.
Whether Huawei can scale fast enough to meet the country’s voracious demand for AI compute remains an open question. For now, Nvidia is out, and Huawei is in.
