The LiDAR Empire

Every self-driving car needs to perceive the world in three dimensions, and for the most demanding systems that means LiDAR, the laser sensor that maps a car’s surroundings centimetre by centimetre. The market for automotive LiDAR is now, overwhelmingly, Chinese. In Yole Group’s 2024 ranking, Hesai led with 33% of the market, RoboSense followed at 24%, and Huawei took 19%, three Chinese firms accounting for roughly three-quarters of global sales.^[1] RoboSense became the first company anywhere to pass one million cumulative automotive-LiDAR deliveries in mid-2025, having more than doubled its 2024 volume.^[2]

Dominance of the market is only half the story. The other half is price. A LiDAR unit that cost on the order of $50,000 a decade ago has fallen toward a few hundred dollars, driven by Chinese volume manufacturing; in November 2025 Hesai launched a roughly $200 unit, positioned explicitly as a rebuttal to the argument that LiDAR is too expensive to belong on an ordinary car.^[3][4] That collapse changes what is possible: a sensor once reserved for six-figure research vehicles is becoming standard equipment on mid-market Chinese EVs.^[4]

A sensor that cost $50,000 a decade ago now sells for about $200, from the same company the Pentagon lists as military-linked.

A commodity, and a flashpoint

Cheap, abundant LiDAR is the quiet enabler beneath China’s assisted-driving boom, and it has become a geopolitical flashpoint. The Pentagon added Hesai to its list of “Chinese military companies” in January 2024; Hesai sued, and in August 2026 a US appeals court found the designation had violated its due-process rights, though the litigation continues and the Pentagon has signalled it will relist on new grounds.^[5] A precise market-share aggregate for “all Chinese firms” is hard to pin to a single source, and shares shift by segment and year, so the numbers above should be read as Yole’s automotive-market figures for 2024, not a fixed total.

The playbook is the one China has now run in three industries. Drive volume up a manufacturing learning curve until unit cost falls below what incumbents can match, at which point the category commoditises and the foreign margin evaporates, solar, then batteries, now the laser eyes of a self-driving car. Commoditisation cuts both ways for investors: it compresses the sensor makers’ own margins even as it enlarges the market for everything built on cheap, abundant perception. The value migrates upward, toward the software that turns a point cloud into a driving decision, while the sensor itself becomes a cheap, ubiquitous and largely Chinese input.

Why it matters for investors

LiDAR is one of the cleanest examples of a category China took by driving cost down a manufacturing learning curve until the incumbents could not follow — the same playbook it ran in solar and batteries. The component is becoming a commodity, which compresses the margins of the sensor makers even as it expands the market for everything built on top of them. The durable value is migrating toward the perception software and the systems integration; the sensor itself is on its way to being cheap, ubiquitous and Chinese.
