A Chinese self-driving company with an unusually blue-chip backer list is heading to market. Momenta plans to raise up to about $751 million (HK$5.89 billion) in a Hong Kong initial public offering (IPO) to fund its autonomous-driving research, Investing.com reported. An IPO is a company's first sale of shares to the public; Momenta is offering roughly 19.9 million shares at about HK$295.60 apiece, with trading expected to begin in early July.
What Momenta does
Founded in 2016, Momenta builds the software and sensors that let cars drive themselves — or, more commonly today, that power ADAS (advanced driver-assistance systems): the lane-keeping, adaptive cruise control and automated parking features now common in new cars. It supplies that technology to automakers rather than building its own vehicles, and its systems are already embedded in more than 900,000 mass-produced cars, the company says. By one industry tally (Frost & Sullivan), Momenta leads the market for urban "level-2" assisted driving by sales volume.
The business is growing fast but not yet profitable: Momenta reported 2025 revenue of about 2.4 billion yuan (~$354 million) with healthy gross margins, alongside a sizeable annual net loss — a reminder that the self-driving race burns cash, which is much of the point of raising money now.
A who's-who of backers
What sets Momenta apart is its investor roster. Global automakers — Toyota, Mercedes-Benz, General Motors and China's SAIC — hold stakes, alongside financial heavyweights including Tencent, BlackRock, Temasek and Singapore's GIC, per Bloomberg. Mercedes and GIC have signed on as anchor investors for the listing itself. That lineup signals how seriously the world's carmakers take Chinese self-driving software — and gives them a window into a supplier many of them depend on.
Why Hong Kong, why now
Momenta had reportedly eyed a US listing before pivoting to Hong Kong amid regulatory friction over Chinese firms listing in America. The timing rides a revival in Hong Kong's IPO market, which has roared back in 2026 as a wave of Chinese technology, EV and AI companies raise capital there. For Hong Kong, landing a marquee autonomous-driving name is a vote of confidence; for Momenta, it's a way to fund an expensive, multi-year fight.
The competitive backdrop
Momenta enters a crowded field. China's autonomous-driving scene is fiercely contested — Pony.ai, WeRide and Baidu's Apollo are scaling up robotaxi fleets across Chinese cities, while globally Tesla and Alphabet's Waymo chase the same prize from different angles. The money raised here is meant to keep Momenta in that race, where leadership hinges on miles of real-world driving data and ever-better software.
The bottom line
Momenta's IPO is a useful gauge of two things at once: investor appetite for Chinese self-driving firms, and the health of Hong Kong as a venue for the region's tech ambitions. The strong strategic backing is real, but so is the cash burn and the brutally competitive market — and, as always with an IPO, the figures here are the proposed terms, which can shift before the shares actually start trading. What's clear is that the business of teaching cars to drive themselves is drawing serious global money, and a chunk of it is now flowing through Hong Kong.
