Nvidia's share of China's AI chip market has fallen to 34%, according to Coinpedia's latest tracking, as Huawei closes the gap in the world's second-largest economy.

That's a sharp reversal for a company that until recently dominated the segment. For practitioners, the number matters because it recalibrates expectations for Nvidia's data center revenue out of China — and signals that domestic alternatives are winning real design wins, not just political goodwill.

What does the 34% figure change?

For buyers and system integrators in China, the shift means Huawei's Ascend lineup is now a credible default rather than a workaround. For Nvidia's investors, it compresses the addressable market just as U.S. export rules keep tightening what the company can legally ship.

The stock-price angle is straightforward: China was a high-margin growth lever, and that lever is shortening. Every point of share Huawei takes is revenue that doesn't come back quickly, even if export restrictions ease later.

Why is Huawei gaining now?

Washington's export controls have already blocked Nvidia's top-end GPUs from the Chinese market, leaving the company to sell cut-down variants. Huawei, meanwhile, keeps improving its domestic silicon and can sell without a Washington veto. That asymmetry does the heavy lifting behind the share shift.

U.S. sanctions kicked off this dynamic years ago, but the 34% figure shows the trend has moved from projection to measurable market fact.

What should watchers track next?

• Whether Nvidia's China share stabilizes or keeps sliding quarter over quarter
• Huawei's production capacity — share gains only stick if it can ship at scale
• Any further U.S. rule changes that could narrow Nvidia's legal product range again

The gap is closing. Whether it closes entirely depends less on Silicon Valley than on Shenzhen's fabs and Washington's rulebook.
