As the development of autonomous driving rapidly advances towards Level 3 and beyond, the automotive industry in China is undergoing a structural shift in its value focus. In recent years, capital markets have concentrated on algorithm models, chip computing power, and vehicle intelligence configurations. However, the core of industrial competition is now moving towards a capability with more long-term value: safety verification and large-scale testing. Under this trend, simulation platforms are no longer just research and development tools but have become critical infrastructure supporting the mass production and regulatory approval of high-level autonomous driving systems, significantly elevating their strategic importance.
According to a report titled "Research on China's Physical AI Simulation and Data Platform" by the global growth consulting firm Frost & Sullivan, the market for end-to-end high-level autonomous driving simulation and data platforms in China has entered a phase of concentrated acceleration. 51Sim, a subsidiary of 51WORLD (06651), leads the Chinese market for end-to-end high-level autonomous driving simulation and data platforms with a 53.5% market share and is establishing sustainable scale barriers and ecosystem advantages.
From a broader industrial perspective, autonomous driving is emerging as one of the most important and earliest large-scale application scenarios for "Physical AI." Frost & Sullivan predicts that with the accelerated expansion of downstream industries such as smart vehicles and embodied intelligent robots, China's Physical AI simulation and data platform sector is entering a significant period of value release. Its total addressable market is expected to exceed RMB 180 billion by 2030.
Physical AI refers to intelligent systems capable of perceiving, making decisions, and acting in the real physical world. The core challenge lies not in a single algorithm's capability but in how to continuously verify and optimize system safety within complex, dynamic, and uncertain environments. Autonomous driving inherently exhibits typical Physical AI characteristics: it must operate in open road environments, interact in real-time with humans and other traffic participants, and bear high safety responsibilities. Consequently, its verification difficulty far exceeds that of purely software-based AI systems.
In this context, simulation and data platforms have become the "training and verification factories" of the Physical AI era. Only through high-fidelity reconstruction, generative completion, and closed-loop simulation operations can millions or even billions of extreme scenario tests be conducted in virtual environments, thereby supporting the development of safe and controllable algorithms. This also explains why autonomous driving is considered the most critical commercial breakthrough for Physical AI—its scale, complexity, and regulatory requirements make it the field with the most urgent need for simulation infrastructure.
51WORLD has established a systematic presence in the Physical AI simulation and data platform sector and is regarded by the market as a representative company, sometimes referred to as the "first stock of Physical AI." Unlike companies focused solely on a single algorithm or software product, 51WORLD's core competency centers on the digitalization of the real world, physical environment reconstruction, and the construction of large-scale simulation verification systems. This capability not only serves autonomous driving but also holds potential for extension into other Physical AI scenarios such as robotics and embodied intelligence.
From a capital market perspective, the value proposition of Physical AI infrastructure companies differs significantly from that of traditional software firms. Customer stickiness is stronger, migration costs are higher, and industry barriers are deeper. Once integrated into an automaker's R&D system and involved in the approval process, a platform often becomes a long-term partner rather than a one-time tool procurement. This "deep integration" attribute provides platform-based companies with greater long-term cash flow stability and potential for scale expansion.
As the approval process for L3 autonomous driving continues, automakers must provide quantifiable, reproducible, and auditable safety verification systems when launching high-level driving functions. Real-road testing is limited by cost and risk, making it difficult to cover the vast number of long-tail scenarios, while end-to-end models are highly dependent on complex interactive environments. Simulation has become the only scalable verification method and a key technical support within the approval framework.
This trend has significantly raised the barriers to entry in the sector. An end-to-end simulation platform requires not only high-fidelity physical and sensor modeling capabilities but also the ability to manage massive data assets, support large-scale concurrent computing, and deeply integrate with automakers' engineering processes. The combination of high barriers and stringent approval requirements is rapidly increasing industry concentration. 51Sim, with its 53.5% market share, firmly holds the top position, exceeding the combined share of the second to fourth players, demonstrating a clear leading advantage. As its customer base expands and scenario assets accumulate, the platform's capabilities are generating network effects, accelerating the stabilization of the industry landscape.
As high-level autonomous driving enters a new phase where mass production and regulatory approval proceed in parallel, industry competition is shifting from a focus on algorithm performance to a contest of systemic capabilities encompassing data, simulation, and verification. Under this logic, platform-based companies capable of long-term support for autonomous driving approval, safety certification, and ongoing operational verification are poised to become the underlying infrastructure providers for the smart car era.
51WORLD and its subsidiary 51Sim represent more than just a simulation software company; they are builders of the infrastructure for the Physical AI era. As autonomous driving, a core Physical AI application, continues to expand, the strategic value of simulation and data platforms is expected to be further amplified. For capital markets, the focus should no longer be solely on the speed of algorithm iteration but on identifying which companies can become the foundational platforms supporting the long-term evolution of Physical AI. Judging by market share, customer ecosystem, and engineering implementation capabilities, 51Sim is positioned at the heart of this industrial trend, while 51WORLD is establishing a clear leadership position in the Physical AI infrastructure arena.
