TL;DR
Huawei's Ascend chips now command roughly half of China's AI accelerator market while Nvidia has collapsed from 40% to 8% share, proving that US export controls built a domestic rival instead of containing one.
What happened
- Huawei holds ~50% of China's AI accelerator market in 2026, up from ~40% in 2025, per Bernstein Research estimates reported by the Associated Press.
- Nvidia's share fell from ~40% to ~8% over the same period, as export restrictions blocked its flagship H100, H200, and B200 from Chinese buyers.
- Huawei targets 1.6 million Ascend dies in 2026, nearly triple the ~600,000 shipped in 2025, with SMIC dedicating 15% to 20% of its advanced-node output to Ascend production.
- The Ascend 950PR, launched earlier this year, delivers 2 petaflops of FP4 compute and 128GB of proprietary HiBL 1.0 memory, bypassing reliance on SK Hynix or Samsung HBM.
- DeepSeek plans to deploy at least 160,000 Ascend 950DT chips at a gigawatt-scale Inner Mongolia campus; ByteDance has committed billions toward 950PR orders.
Why it matters
- US export controls handed Huawei a captive market: blocking Nvidia's best silicon didn't make domestic alternatives worse by comparison, it gave Huawei guaranteed demand to fund each next generation.
- HBM self-sufficiency is the strategic breakthrough: HiBL 1.0 removes the memory bottleneck that Semianalysis flagged as the real ceiling on Huawei's scale, not chip design or fab capacity.
- A Bloomberg Intelligence survey finds Chinese companies plan to shift 46% of AI accelerator budgets to domestic chipmakers within a year, up from 30% today, driven by Beijing procurement rules as much as chip performance.
- China is preparing a ~$295 billion AI data center plan favoring domestic chips and state carriers, which would lock in Huawei's infrastructure role for years.
- Nvidia's China revenue was worth billions annually before restrictions tightened; Bernstein's math implies most of that has already transferred, even though Nvidia remains dominant everywhere else.
What to watch next
- SMIC fab utilization above 93% leaves almost no slack: watch whether new tooling approvals or capacity expansions allow Huawei to hit or exceed the 1.6 million die target.
- Ascend 960PR is due in 2027 with higher FP4 throughput and 2.2TB/s interconnect bandwidth; its reception will show whether Huawei can close the performance gap on workloads beyond prefill and recommendation.
- The $295 billion state data center plan: procurement decisions will confirm whether Beijing converts policy intent into locked-in Ascend deployments at national scale.
