China's two largest contract chip manufacturers, Semiconductor Manufacturing International Corporation (SMIC) and Hua Hong Grace Semiconductor, reported triple-digit profit surges in the second quarter, driven by a spike in demand for domestic artificial intelligence chips that fall outside US export controls.
SMIC's net profit jumped 261.7 per cent year on year to US$479.2 million in the June quarter, while Hua Hong's net profit rose 385.9 per cent to US$38.6 million. The growth reflects how Chinese AI developers, restricted from advanced foreign semiconductors, are turning to domestically manufacturable alternatives.
The performance illustrates how technology sanctions are reshaping industrial advantage. As Washington restricts access to leading-edge chips, a captive market has emerged for China's national foundry champions, testing the limits of global supply chain decoupling.
