China's Biren posts 2,000% revenue growth as Nvidia, AMD exit market

Chinese AI accelerator maker Biren Technology reported roughly 2,000% year-over-year revenue growth in the first half of 2026. The surge coincides with Nvidia and AMD effectively exiting the Chinese market under US export controls.

Why it matters: This is direct evidence that export controls are accelerating China's domestic chip industry rather than stalling AI progress there, the opposite of the policy's stated goal. It strengthens the case that Chinese accelerators will keep closing the gap regardless of US restrictions, reshaping the long-term competitive balance in AI hardware.
