A Chinese company making the “eyes” of self-driving cars is at the center of a growing national security fight, and its deepening ties to Nvidia are making Washington increasingly nervous.
Hesai Technology, listed on both Nasdaq and the Hong Kong Stock Exchange, has built itself into a global lidar powerhouse. It also happens to be on the Pentagon’s list of companies with alleged ties to China’s military.
The Nvidia connection and why it matters
Hesai partnered with Nvidia on the DRIVE Hyperion platform, an autonomous driving ecosystem that includes the Hyperion 10 lidar system announced in January 2026. Lidar is the laser-based technology that lets self-driving vehicles see the world in 3D.
The core concern is straightforward: lidar sensors collect extraordinarily detailed spatial data about their surroundings. Roads, buildings, military installations, critical infrastructure. US officials and analysts argue that a Chinese-made sensor deployed across American cities and highways could serve as a data collection tool, whether by design or by exploitation.
