Chinese Autonomous Driving Firm Momenta Considers Hong Kong IPO Following U.S. Approval Expiration

Momenta's U.S. Listing Approval Lapses, Hong Kong Eyed for 2026 Debut

Momenta, a prominent Chinese autonomous driving developer, is reportedly evaluating a potential initial public offering (IPO) in Hong Kong by 2026. This consideration follows the expiration in June of its approval from China's securities regulator to list in the United States. While the plan is still in its nascent stages and subject to change, the company has informed some investors about this prospective shift. Momenta boasts significant backing from global automotive giants, including Toyota Motor, Bosch, and reportedly Mercedes-Benz and Hyundai, reflecting its standing in the advanced driving assistance systems (ADAS) sector, a field often compared to Tesla's self-driving capabilities.

Geopolitical Realignment and Regulatory Shifts Drive Listing Preferences

The potential pivot by Momenta underscores a broader strategic recalibration among Chinese technology firms regarding their international listing venues. Heightened U.S.-China geopolitical tensions and stringent regulatory frameworks, such as the Holding Foreign Companies Accountable Act (HFCAA), have created an environment of uncertainty for Chinese companies seeking to access U.S. capital markets. The HFCAA, with its threat of delisting for non-compliance with U.S. audit standards, has prompted many U.S.-listed Chinese entities to pursue secondary or dual listings in Hong Kong as a hedge against regulatory risks. This trend is evident in figures from early 2025, where over 75% of U.S.-listed Chinese companies by market capitalization had already established a presence in Hong Kong.

Several other Chinese entities have similarly opted for or are considering Hong Kong listings. For instance, AVATR Technology, an electric vehicle (EV) startup backed by Huawei and CATL, is preparing for a Hong Kong IPO in late 2025 or early 2026, aiming to raise up to $1 billion (HK$7.8 billion) for global expansion. Similarly, IQIYI, China's second-largest video streaming platform, pursued a secondary listing in Hong Kong, raising $200-$300 million to mitigate U.S. regulatory exposure. Even the world's largest battery maker, Contemporary Amperex Technology Co. Ltd. (CATL), debuted on the HKEX in May 2025, raising $5.25 billion in the largest equity transaction of the year thus far.

Hong Kong's Ascendancy as a Global IPO Hub

This shift has significantly bolstered Hong Kong's position in the global equity fundraising landscape. In the first half of 2025, the amount raised on the main stock exchange surged more than eightfold to $49.2 billion, primarily driven by follow-on offerings from mainland Chinese companies. The Hong Kong Exchanges and Clearing Ltd. (HKEX) hosted 210 IPOs and follow-on offerings during this period, a substantial increase from 182 deals raising $5.26 billion in the same period of 2024. This performance positions Hong Kong as a top global destination for equity fundraising, a trend experts believe will continue.

Frank Bi, a Hong Kong-based partner at Ashurst, commented on this robust activity, stating, "> It is really a big year for Hong Kong and I don't see any sort of pushback from this kind of trend." He noted nearly 100 new applications this year, including at least 20 A-share listed mainland Chinese companies, attracted by the opportunity to gain overseas profiles and leverage HKEX's comparatively shorter vetting process. Deloitte forecasts that Hong Kong could see over 80 IPOs raising HKD 250 billion-280 billion in 2025, potentially outperforming U.S. exchanges.

Outlook: A Persistent Trend Driven by Strategic Realignment

The trajectory suggests that the repositioning of Chinese IPOs towards Hong Kong is a persistent trend, rather than a transient market fluctuation. Factors such as a potential interest rate cut cycle by the U.S. Federal Reserve are expected to channel more overseas capital into Asian markets, including mainland China and Hong Kong, thereby providing ample liquidity and a more favorable valuation environment. As U.S.-China relations remain a critical variable, and with Hong Kong continuously refining its regulatory framework to attract listings, the Asian financial hub is poised to further solidify its role as a primary fundraising gateway for Chinese technology and growth companies. Investors will closely monitor regulatory developments in both the U.S. and China, alongside the performance of recent Hong Kong listings, to gauge the long-term implications of this evolving capital market dynamic.
