Nvidia's AI chip shipments to China dropped 44% YoY to 678,000 in H1 2026, cutting its market share to 34% as US export restrictions and rising domestic competition bite.
IDC’s latest market data shows Nvidia’s shipments of data‑centre AI chips to China plunged 44 % year‑on‑year in the first half of 2026, falling to 678 000 units. The decline pushed the U.S.‑based firm’s share of China’s AI‑chip market to 34 %, a sharp drop from its long‑standing dominance.
The slide is attributed to two converging forces. Tightened U.S. export controls have limited Nvidia’s ability to sell its GPUs and related accelerators to Chinese customers, while a wave of domestic competitors, led by Huawei, has accelerated its own production. Huawei shipped 572 000 units in the same period, capturing a 28 % market share and overtaking Nvidia as the top supplier. Nine of the eleven Chinese AI‑chip makers tracked by IDC reported growth, and non‑GPU accelerators surged 80 %, overtaking traditional GPUs for the first time. Four Chinese firms now account for 95 % of that fast‑growing segment.
Why it matters: Nvidia’s chips have been the backbone of China’s AI‑driven cloud and enterprise workloads. A shrinking foothold not only dents the company’s revenue outlook but also signals a broader shift in the global AI‑hardware supply chain. For Washington, the data underscores the impact of export curbs, while Beijing sees a tangible payoff from its push for home‑grown silicon, reducing reliance on foreign technology and potentially reshaping the competitive landscape for AI compute worldwide.
What to watch next: Upcoming IDC quarterly updates will reveal whether the trend continues into the second half of the year. Analysts will also monitor Huawei’s product roadmap and the emergence of other Chinese players in the accelerator market. On the supply‑side, Nvidia’s response—whether through new chip designs, strategic partnerships, or lobbying for policy adjustments—will be critical to its ability to regain ground in China’s rapidly expanding AI ecosystem.
