China's AI accelerator supplier Biren posts 2,000% year-over-year revenue growth — US export controls benefit homegrown chips as Nvidia and AMD exit market

Chinese AI accelerator supplier Biren Technology reported nearly 2,000% year-over-year revenue growth in the first half of 2026, driven by U.S. export controls that halted NVIDIA and other American co... Read original →

U.S. export controls on AI chips have fundamentally reshaped China’s AI computing supply chain. The exit of NVIDIA and others has triggered a surge in domestic players like Biren Technology, which reported a 2,000% YoY revenue increase. However, this growth is built on a fragile foundation—Biren’s tech stack still relies on CUDA compatibility, increasing migration costs. The shift accelerates the move toward independent architectures, yet current 3nm BR chips face manufacturing scalability and yield issues. Compliance risks are mounting as companies balance supply chain resilience with R&D expenses, especially at SMIC. Competitors like Huawei and Cambricon are leveraging ecosystem and capital advantages to solidify their positions. Over the next 12–24 months, the decoupling trend between China and the U.S. will deepen, reinforcing domestic substitution. Yet, Biren and peers must overcome production bottlenecks to transition from 'existence' to 'competitiveness'.
