Nvidia once owned a staggering 95% of China’s AI chip market. Today, that number sits at zero. This isn’t an exaggeration or a typo, but the direct result of US export restrictions that have systematically locked the American chip giant out of the world’s second-largest economy.
CEO Jensen Huang has acknowledged the collapse, conceding Nvidia has effectively lost its entire Chinese AI accelerator business. The big winner here? Huawei, which is quickly stepping in as China’s primary supplier of advanced AI hardware.
How US export controls erased Nvidia’s China business
The trouble began in October 2022, when the US Commerce Department introduced sweeping export restrictions on advanced semiconductor sales to China. The initial rules barred Nvidia from shipping its top-tier A100 and H100 GPUs to Chinese customers.
Nvidia tried to adapt. The company designed downgraded chip variants specifically to comply with the new performance limits. But then Washington tightened the rules again in October 2023, effectively killing those workaround products too.
It wasn’t just the US government squeezing Nvidia from one side. Chinese authorities also instructed major tech firms to stop buying Nvidia’s AI chips entirely. Both governments were pushing Nvidia out of the market simultaneously, from opposite directions.
Huawei steps into the vacuum
With Nvidia out of the picture, Huawei has become the obvious alternative, backed by strong state support and an increasingly capable domestic chip ecosystem. Major Chinese tech companies, from Baidu to Alibaba to Tencent, are now turning to Huawei’s Ascend series processors for their AI training and inference needs.
The policy paradox nobody wants to talk about
The stated goal of US export controls was to slow China’s AI development by restricting access to cutting-edge chips. But policy analysts are starting to ask uncomfortable questions about whether that assumption was flawed.
By cutting Nvidia off from the Chinese market entirely, the US may have accomplished something no Chinese industrial policy could have done on its own. It gave domestic chip companies like Huawei a captive market worth billions of dollars in annual demand, with zero foreign competition.
Before the export bans, Chinese companies had little reason to switch away from Nvidia. The CUDA software ecosystem was deeply entrenched, the hardware was best-in-class, and switching costs were massive. The export controls eliminated all those barriers overnight. Companies that would have happily stayed on Nvidia’s platform for another decade were suddenly forced to invest in Huawei’s ecosystem instead.
The irony is hard to ignore. What was meant to slow China’s AI development might have actually accelerated it, at least as far as domestic chip independence goes.
