Washington wanted to wall China off from Nvidia. Instead, it walled Nvidia out of China — and handed the world's second-biggest AI chip market to the one company America spent a decade trying to contain. "It's pretty hard to collect data about the market share of Nvidia in China," Huawei's rotating chairman Eric Xu said this week, with a straight face. "But based on the data we have collected, Ascend has surpassed Nvidia."

Speaking at Huawei Connect, Xu said the company's Ascend AI accelerators now outsell Nvidia in China, by both revenue and market share. Let's be honest about the fine print: he offered no audited numbers, the data is Huawei's own, and counting Nvidia's share in China is admittedly a strange exercise — because officially, there isn't any.
But here's the thing. When the incumbent CEO says his China market share went from 95% to zero, and the challenger says it's now number one, you don't need Huawei's spreadsheets to know something big happened in between. You just need a calendar.
The timeline reads like a slow-motion own goal:
Nvidia didn't lose China to a better chip. It lost China to a law.
Here's what the policy assumed: no Nvidia chips, no Chinese AI. Here's what actually happened: no Nvidia chips, no Nvidia revenue — and a Chinese AI buildout that SemiAnalysis now ranks second-largest on Earth, with domestic capex racing toward $100 billion a year.
Demand didn't disappear. It re-routed. Bernstein estimates relayed by The Economist put Nvidia at roughly 40% of China's AI chip market in 2025, collapsing to around 8% in 2026 — with Huawei rising to about half. DeepSeek, China's breakout AI lab, now co-designs and open-sources software that runs its models on Ascend silicon. Every model trained on Ascend is a future that never buys an H200.
Huawei can't buy EUV machines, so its chips are made on older nodes with lower yields. A single Ascend still loses a footrace with a single Nvidia flagship. So Huawei changed the race. Its answer is arithmetic: strap more chips together.
Is this inefficient? Enormously. More chips, more watts, more racks. But China has cheap electricity, deep pockets, and — thanks to export policy — a completely captive customer base. Brute force is only stupid when you have a smarter option available.
Here's the part Washington may not have priced in. Xu says demand for Ascend chips outstrips supply — Huawei can't even produce enough for China, which is why it's limiting overseas sales to a trickle. And once Chinese AI labs build their training pipelines on Huawei's chips, its CANN software stack, and its CloudMatrix interconnect, they don't switch back the day an H200 clears customs. Distribution moats die fast. Stack moats compound.
Xu expects many of China's leading model developers to begin training on Ascend systems next year. If that lands, the substitution isn't a workaround anymore — it's the default.
Skeptics — and there are serious ones — say none of this proves Huawei has "caught" Nvidia. The Council on Foreign Relations argues Huawei still lags badly on per-chip performance, HBM memory supply, and manufacturing yield, and that easing controls would hand China a two-to-three-year compute windfall. Analysts like Noah Smith note Huawei doesn't expect a single chip matching the H200 until late 2027 at the earliest.
Also true: Nvidia has never been richer — about $194 billion in data center revenue last fiscal year. China was 17% of its revenue in fiscal 2024; now it's in the low single digits. Nvidia didn't shrink. It just sold its future customers to the only company on Earth with both the motive and the mandate to replace it.
The point of export controls was to buy time — keep China's AI a few years behind. Instead, Washington ended up as the silent partner in Huawei's domination of the world's second-largest AI chip market: zero revenue for Nvidia, near-total substitution for Huawei, and a full-stack competitor that now has funding, demand, and a captive test bed no startup could ever buy.
The wall was supposed to keep the chips out. Turns out it mostly kept the competitor in — and made it strong.
