Chinese Autonomous Driving Startup Momenta Clears Hong Kong IPO Hearing, Backed by GM, Mercedes, and Toyota

Momenta Passes the Hearing. Now the Hard Part.

Momenta filed its post-hearing listing application with the Hong Kong Exchanges and Clearing (HKEX) on June 23, 2026, according to Car News China. The company passed its listing hearing, which is the last major procedural gate before an IPO can proceed. No listing date and no fundraising target have been disclosed.

Founded in 2016 by CEO Cao Xudong, Momenta specializes in L2 advanced driver-assistance systems (ADAS) and is pushing toward L4 autonomous fleet deployment. The company sits at the intersection of two things markets are watching closely: Chinese tech going public in Hong Kong and the global race for autonomous vehicle software.

Who Owns It, and Why That Matters

The pre-IPO shareholder table reads like a global auto industry summit. According to the listing documents cited by Car News China, SAIC Motor holds 9.45%, General Motors holds 9.37%, Mercedes-Benz holds 6.39%, and Toyota holds 1.54%. BYD, Chery, and Hyundai also hold stakes.

That cross-border ownership structure is strategically significant. Caixin Global reports that Momenta's international backing positions it to capture overseas market share at a moment when domestic rival Huawei faces hard limits in Western markets due to U.S. sanctions. Huawei's automotive business unit cannot easily partner with Western automakers for the same reason. Momenta, by contrast, has already landed those partnerships.

Gasgoo adds depth to the client picture: beyond the shareholders, Momenta's customer list includes BMW, Audi, Volkswagen, and Honda. For a ten-year-old Chinese startup, that represents an unusually broad Western-facing commercial footprint.

The Financials: Strong Margin, Real Losses

Momenta generated 2.41 billion yuan ($354.4 million USD) in revenue in 2025, with a gross margin of 71.6%, according to Car News China. Those are strong top-line numbers for a company at this stage.

The net loss, however, was 3.46 billion yuan ($508.8 million USD). The company attributes the bulk of that to 1.87 billion yuan ($275 million USD) in R&D spending, plus non-cash charges including employee equity costs and fair value changes in preferred shares. Strip those items out, and the adjusted operating loss for 2025 was 300 million yuan ($44.1 million USD), narrower than the adjusted loss in 2024.

Profitability remains a future prospect. The IPO proceeds, whenever raised, are earmarked for next-gen intelligent driving R&D, AI computing infrastructure, robotaxi commercialization, and overseas L4 fleet deployment, per Car News China.

Market Share: Dominant, but Contested

Frost & Sullivan data cited by Caixin puts Momenta's global market share in the urban L2 ADAS segment at 64.5%, based on vehicle sales volume. By the end of 2025, the company had secured design wins for 170 vehicle models, with 68 in mass production.

Gasgoo's analysis adds granularity. As of April 2026, Huawei (including its affiliated brands) and Momenta together held a combined 72.8% share of the domestic city NOA (Navigate on Autopilot) market, a near-duopoly. Momenta alone held roughly 30% of that combined figure. Narrow the scope to the third-party supplier segment — excluding automakers building systems in-house — and CIC China Insights Consultancy puts Momenta's share at 65% for the period from March 2025 through February 2026.

Gasgoo also highlights an unusual structural relationship: SAIC Motor is Momenta's largest institutional shareholder, while Momenta holds a stake in SAIC's IM Motors brand. The two companies are cross-shareholders. Gasgoo describes this as a mutual-risk alliance that goes well beyond a standard procurement arrangement.

The Strongest Counter-Argument

Skeptics of Momenta's valuation case have a legitimate point: market share in a fast-moving tech sector is not durable by default. Gasgoo notes directly that as automakers accelerate in-house autonomous driving development, the commercial rationale for buying from a third-party supplier weakens. Every major OEM that builds its own system is one fewer potential Momenta customer.

In April 2026, Momenta unveiled its R7 reinforcement learning world model. The first vehicle to feature it is the SAIC Volkswagen ID. ERA 9X, with an OTA software rollout planned for the third quarter of 2026, according to Gasgoo. If R7 delivers on its performance benchmarks and integration costs stay competitive, it strengthens the supplier case. If it doesn't, automakers have cover to accelerate internal alternatives. The IPO timing means public investors will bear that technology execution risk.

What's Still Unresolved

The single biggest open question as of June 26, 2026 is how much Momenta intends to raise and at what valuation. Neither the company nor the exchange has disclosed a target. The fundraising figure, when it comes, will be the first market test of whether Western and Asian institutional investors are willing to price Momenta's dominant market share against its ongoing losses and the geopolitical complexity of a Chinese tech IPO in the current environment.

According to Gasgoo, the real-world performance of the R7 model in the SAIC Volkswagen rollout this quarter will directly influence the volume of future automaker orders. That makes the Q3 OTA deployment a near-term signal worth watching before the IPO pricing process concludes.
