The Scaling Era of Autonomous Mobility

The global autonomous vehicle sector is undergoing a fundamental transition. What began as localized pilot programs and experimental testing is rapidly maturing into large-scale commercial fleet operations. At the core of this transition is the hardware that allows these vehicles to perceive and navigate the physical world safely. Lidar technology has emerged as an indispensable component for high-level autonomous driving, providing the precise spatial perception required to navigate complex urban environments.

In this highly competitive landscape, Hesai Group (Nasdaq: HSAI; HKEX: 2525) has established a commanding position. According to the Robotaxi 2026 report published by Yole Group, the physical AI infrastructure company has been recognized as the world's leading supplier of robotaxi lidar. This leadership comes at a critical juncture as operators worldwide prepare to expand their fleets, shifting their focus from initial technology validation to industrial-scale deployment.

Analyzing Hesai's Market Dominance

The quantitative data from Yole Group's dedicated study highlights the extent of Hesai's market leadership. In 2025, Hesai secured a 62% share of the global robotaxi lidar market. This figure represents a share larger than all other lidar suppliers combined, underscoring the company's strong position in the autonomous driving ecosystem.

This market share also reflects steady upward momentum. In Yole Group's previous report, Hesai's market share was recorded at 61%. The increase to 62% in 2025 demonstrates the company's ability to maintain and expand its market presence even as competitors enter the space and existing players attempt to scale their operations.

A Diversified Global Partner Ecosystem

One of the key indicators of Hesai's market resilience is the diversity of its customer base. Rather than relying on a single major customer or a localized geographic market, the company's lidar technology has been integrated into leading Level 4 robotaxi and autonomous vehicle programs across the globe.

Hesai's technology has been selected by a wide array of prominent industry players, including:

  • Baidu Apollo Go
  • Pony.ai
  • WeRide
  • DiDi
  • Motional
  • Aurora
  • KargoBot

This broad adoption across multiple platforms and operating environments indicates that Hesai's hardware is capable of meeting diverse technical requirements and operating under varied regulatory frameworks. By securing partnerships with both East Asian autonomous driving pioneers and Western technology developers, the company has insulated itself from regional market fluctuations and established a truly global footprint.

The Road to 2031: Projecting Fleet Expansion

The demand for reliable lidar technology is projected to grow exponentially. Yole Group's market analysis provides a clear picture of this trajectory, projecting that the global robotaxi fleet will expand from approximately 10,000 vehicles in 2025 to 331,000 vehicles by 2031.

This massive scaling effort will place unprecedented demands on the autonomous vehicle supply chain. As operators transition from managing small test fleets to operating large numbers of vehicles, their hardware requirements will shift. The industry will require:

  • Precise perception capabilities that remain reliable in highly complex and unpredictable real-world environments.
  • Consistent automotive-grade quality to minimize vehicle downtime and ensure passenger safety.
  • Highly reliable supply chains capable of delivering advanced sensor technology at scale.

Meeting these requirements is essential for operators aiming to achieve commercial viability and public trust.

Executive Perspectives on the Next Phase of Deployment

Dr. Yifan “David” Li, Co-Founder and Chief Executive Officer of Hesai, emphasized the shifting priorities of the industry as it enters this new phase. He noted that robotaxis are moving into an important next phase, where operators are increasingly focused on scaling deployment and delivering reliable autonomous mobility in real-world environments. According to Dr. Li, this transition raises the bar for every component on the vehicle.

Dr. Li explained that operators require perception systems they can rely on across more vehicles, more roads, and more hours of operation. He attributed Hesai's continued market leadership to the trust earned through years of close collaboration with robotaxi developers, as well as the company's proven ability to deliver high-quality hardware at scale.

Next-Generation Technology and the Future of Autonomous Driving

To maintain its market position as the industry scales toward the 2031 projections, Hesai is actively developing its next-generation hardware. The company is focusing its development efforts on its flagship lidar platform designed for Level 3 and higher autonomous driving.

At the center of this technological evolution is an upgraded ETX platform. This platform is engineered to meet the rigorous demands of advanced autonomous systems, offering the enhanced performance and reliability required for both consumer vehicles and commercial robotaxi fleets. By advancing this platform, Hesai aims to address the evolving needs of the autonomous driving market, ensuring that its technology remains at the forefront of the physical AI infrastructure sector.
