Tencent takes minority stake in Hangzhou BCI chip developer Nanochap Electronics through Shanghai Qishan Investment vehicle
Tencent Holdings has acquired a minority equity stake in Nanochap Electronics, a Hangzhou-based fabless semiconductor company specialising in neural interface and biosensing SoCs for brain-computer interface and medical device applications. The investment was disclosed through a 28 May 2026 business registration filing showing Shanghai Qishan Investment, a Tencent subsidiary, added as a new shareholder. Nanochap's registered capital increased to RMB 16.8853 million. Exact stake size and investment amount have not been publicly disclosed. The move follows the April 2026 StairMed funding round in which Alibaba led and Tencent joined, and signals a sustained pattern of Chinese big-tech equity participation in the country's BCI silicon supply chain.
