China Proposes Export Controls on AI Models and Chips

On October 16, 2026, Bloomberg reported that China proposed adding advanced artificial intelligence technologies to its export-control list. The draft covers 23 items, including AI models and chips, aiming to restrict overseas transfers of homegrown advancements in this strategically important sector. This move signals a tightening of Beijing's control over domestic AI progress, potentially impacting global supply chains for Chinese-developed AI hardware and software.

Nvidia’s China Share Falls to 34% as Huawei Ascends to 28%

New data from IDC, cited by Reuters and other outlets on October 13, 2026, shows Nvidia’s share of China’s data center AI chip market fell to 34% in the first half of 2026. Huawei’s market share rose to 28%, bringing the gap between the two rivals to just six percentage points. Nvidia’s shipments of AI accelerators to China dropped 44% year-over-year to 678,000 units, driven by U.S. export restrictions and the rise of domestic competitors like Huawei’s Ascend series.

Non-GPU Accelerators Outpace GPUs in China for First Time

According to a Huxiu report published around October 14, 2026, non-GPU accelerators have surpassed GPU shipments in China’s AI chip market for the first time. This shift highlights the growing dominance of specialized domestic accelerators like Huawei’s Ascend and Cambricon chips, which are increasingly preferred by local cloud providers and state-backed projects due to supply chain security concerns and performance optimizations for specific workloads.

Huawei Claims 50% Domestic Market Share via Cluster Interconnect

Huawei’s rotating chairman Xu Zhijun stated during the Huawei Connect conference that Huawei’s Ascend AI chips have achieved a 50% market share in China, surpassing Nvidia’s 8% in that specific segment. While this figure contrasts with IDC’s broader data center metrics, Huawei attributes this success to overcoming single-chip process limitations through advanced cluster interconnect technologies, allowing their systems to compete effectively despite SMIC’s manufacturing constraints.

Local view

Chinese media outlets are framing the recent market shifts as validation of the "domestic substitution" strategy. Sina reports highlight that despite U.S. export controls, Chinese AI models are now "very, very close" to American counterparts, with Rakesh Kumar of Fortune noting that controls spurred China to build its own robust chip ecosystem.

ChainCatcher and Phoenix Technology emphasize the specific decline in Nvidia’s shipments, citing IDC data to show that U.S. restrictions have successfully accelerated the adoption of domestic alternatives like Huawei Ascend and Cambricon. Local analysts note that while single-chip performance still lags behind Nvidia’s latest offerings, the ecosystem maturity and supply chain resilience of Chinese chips are becoming decisive factors for domestic buyers.

Context & numbers

• Market Share: Nvidia holds 34% of China’s data center AI chip market (H1 2026); Huawei holds 28%.
• Shipment Volume: Nvidia shipped 678,000 AI accelerator units to China in H1 2026, a 44% year-over-year decrease.
• Total Market: Total AI accelerator shipments in China exceeded 2 million units in H1 2026.
• Export Control List: China’s proposed draft includes 23 AI technology items subject to potential export restrictions.

On the radar

• Finalization of Export List: Watch for the official publication of China’s revised export control list, which may include specific AI chip models and software frameworks.
• SMIC Capacity Allocation: Continued scrutiny on how SMIC allocates its limited N+2 and N+3 capacity among Huawei, Cambricon, and other domestic clients amid rising demand.
• US License Approvals: Monitor BIS decisions on case-by-case licenses for Nvidia H200 and AMD MI325X exports to China, which remain under strict review since the January 2026 policy revision.
