Charts: Nvidia's China AI chip lead shrinks 80% as Huawei closes in

What happened

Nvidia's lead over Huawei in China's AI accelerator market has narrowed by 80% in a year. According to IDC, Huawei shipped 572,000 Ascend chips in the first half of 2026, securing a 28% market share, just 6 percentage points behind Nvidia, compared with a 31pp gap a year earlier. This brings CEO Jensen Huang's warnings about losing the US$50 billion AI chip market in China closer to reality. The source does not state the cause of the market share change.
