Your AI and this story

  • GPT-6 Astra166 days after its cutoff
  • Claude Opus 5.5105 days after its cutoff
  • Gemini 3.8 Flash196 days after its cutoff
  • Grok 4.7135 days after its cutoff

None of these four assistants can know about it. The closest, Claude Opus 5.5, stops 105 days before it.

Key facts

  • Nvidia, H1 2026: 678,000 chips shipped in China, -44% year over year; share 34% (IDC via Reuters)
  • Huawei, H1 2026: 572,000 chips, share 28%; up from ‘more than 300,000’ in H1 2025
  • GPU shipments fell 26% to 991,000 units; non-GPU accelerators rose nearly 80% to 1.016 million and took the volume lead
  • Huawei, Alibaba’s T-Head, Baidu’s Kunlunxin and Cambricon made up 95% of the non-GPU segment; Kunlunxin, Cambricon and Hygon gained share
  • Implied total market: about 2.0 million accelerators in the half (sum of the two segments; our arithmetic)
  • Comparison: for full-year 2025 IDC had Nvidia at about 2.2 million cards and 55% of roughly 4 million, Chinese vendors at 41%, Huawei at about 812,000 (Reuters, April 1, 2026)
  • Causes named: US export controls limit what Nvidia can sell, and China often requires import approvals even for compliant parts

What happened

Reuters reported new figures from the research firm IDC on China’s market for AI accelerators used in data centers. In the first half of 2026 Nvidia’s shipments fell by 44% and its share dropped to 34%, from 55% for the whole of 2025. Huawei nearly doubled its shipments and now stands six points behind. The fastest-growing part of the market is non-GPU accelerators, where four Chinese suppliers hold 95%.

Why it matters

China was once a market Nvidia dominated with over 90%. The IDC numbers show that export controls and Beijing’s own import approvals have moved a majority of the volume to domestic chips within about 18 months. Unit counts say nothing about performance per chip, so Nvidia’s share of computing power may differ from its share of units.
