When a Chinese family buys a car with assisted driving this year, there is a good chance a small chip made by a company most Western readers have never heard of is making the decisions. Horizon Robotics (地平线) is the compute brain inside an estimated one in three intelligent-driving vehicles sold by Chinese brands. Its story is not about a single breakthrough chip. It is about what happens when a country's car market decides, almost overnight, that self-driving features are no longer a luxury extra but a baseline expectation — and one supplier ends up powering a large slice of that shift.
Key takeaways
- Horizon Robotics (地平线, 9660.HK) listed on the Hong Kong Stock Exchange on 24 October 2024, raising about US$696 million and becoming the largest technology IPO in Hong Kong that year.
- The company says it held roughly 34% of the domestic-branded passenger-car intelligent-driving compute market in 2024, with its solutions in about 290 vehicle models across 27 automakers and 42 brands.
- Revenue reached RMB 2.38 billion (≈ US$330 million / ≈ HK$2.6 billion) in 2024, up 53.6% year on year, but the business remained unprofitable, posting an adjusted net loss of RMB 1.68 billion (≈ US$240 million).
- Its Journey 6 (征程6) family of automotive compute chips entered mass production in early 2025, with the high-end Journey 6P (征程6P) taped out and targeted at full-scenario autonomous driving.
- The open question is durability: Horizon's growth is tied to automakers that are cutting prices aggressively, and the company's own spending on R&D still exceeds its revenue.
From a 2015 startup to a default choice
Horizon was founded in 2015 by Yu Kai (余凯), a former Baidu executive, with a focused bet: build purpose-designed chips and software for vehicles rather than adapt general-purpose silicon. That bet paid off as Chinese automakers raced to add driver-assistance features. According to the company's own figures, by the end of 2024 its solutions had been delivered in roughly 7.7 million sets cumulatively, with about 2.9 million shipped during 2024 alone.
The 2024 Hong Kong listing was the moment the strategy went mainstream. Reuters reported that the stock opened 28.3% above its HK$3.99 offer price after the company sold 1.355 billion shares and raised US$696 million — the biggest Hong Kong tech IPO since SenseTime's 2021 listing. The deal mattered less for the money than for the signal: a Chinese automotive-chip designer had become a public, internationally traded company with marquee backers.
The product that changed the math
The turning point was the Journey 6 (征程6) series, launched in 2024. Unlike earlier generations built for specific tiers of assistance, Journey 6 was designed as a scalable family covering everything from basic lane-keeping to high-level autonomous driving (高阶自动驾驶). Horizon says more than 20 automaker brands adopted it for over 100 mid- and high-tier models. BYD's "God's Eye" (天神之眼) system and Geely's "Qianli Haohan" (千里浩瀚) both build on Horizon hardware.
In early 2025 the company began producing Journey 6, and its top-end Journey 6P (征程6P) reached tape-out, completing real-vehicle validation within 100 hours according to the company. On top of the chip family sits Horizon SuperDrive (HSD), a full-scenario driving solution that the company says will reach its first production vehicle in the third quarter of 2025. The integrated hardware-plus-software model is exactly what cost-conscious automakers want: one supplier, one stack, less in-house engineering.
According to Li An, chief scientist at BrainNet (脑机网), China's advantage in automotive intelligence is increasingly about the full stack — chip, software, and deployment scale together — rather than any single specification, and that integration is what lets local suppliers move faster than global incumbents.
The uncomfortable financial picture
The growth is real, but so are the losses. Horizon's 2024 revenue of RMB 2.38 billion (≈ US$330 million) came with gross profit of RMB 1.84 billion (≈ US$260 million) and a healthy gross margin of 77.3%, lifted by higher-margin licensing and services revenue. Yet the company posted an adjusted net loss of RMB 1.68 billion (≈ US$240 million), and its R&D spend of RMB 3.16 billion (≈ US$440 million) actually exceeded revenue. In other words, Horizon is buying market share with engineering investment it has not yet earned back.
That is a defensible strategy in a land-grab phase, but it depends on automakers keeping their intelligent-driving promises. The risk is concentration: a handful of large Chinese OEMs account for most of Horizon's volume, and those same OEMs are locked in a brutal price war that pressures every supplier's margins.
Why this matters beyond China
Two things make Horizon a global story. First, it shows how fast a domestic supply chain can scale when a huge home market decides a feature is table stakes — a pattern other regions are now watching. Second, Horizon's licensing-and-services model, where it earns not just from chips but from software and royalties, is the same playbook Nvidia and Mobileye use, and it is being tested at scale in the world's largest car market.
For readers tracking the semiconductor cold war, Horizon is also a useful counterpoint to the headline obsession with training GPUs. A great deal of the real AI silicon volume in the coming decade will sit inside cars, running perception and planning models at the edge, and Chinese designers are already shipping those parts by the millions.
Honest limitations
This article relies on the company's own disclosures and state-aligned Chinese financial media for several figures, including the 34% market-share claim and the Journey 6P validation timeline; independent, non-Chinese verification of those specific numbers is limited. Market-share percentages reflect the domestic-branded passenger-car segment, not the global market, and methodologies differ between research houses. The financial figures are from Horizon's 2024 annual results; 2025 interim data was not centrally verified here. Finally, the competitive landscape is moving quickly, with rivals such as Huawei's Ascend (昇腾) automotive units and Black Sesame (黑芝麻) also active, so rankings may shift.
What readers can do now
- If you follow semiconductors, track automotive-edge AI chips (智能驾驶芯片) as a distinct, high-volume category alongside data-center accelerators — it is where many Chinese fabs and designers are shipping today.
- Watch Horizon's quarterly revenue-versus-R&D trend: a narrowing gap between the two is the single clearest signal that the land-grab is converting to profit.
- For context on China's compute buildout, pair this with coverage of domestic GPU and memory makers — the car is becoming one of the largest AI hardware markets most outsiders ignore.
