HKEX Welcomes Its Largest IPO of the Day
Today (July 8th), Momenta successfully listed on the Hong Kong Stock Exchange, becoming the "first Physical AI stock." The company, founded in 2016 by Tsinghua University alumnus Cao Xudong, focuses on autonomous driving as an entry point into Physical AI research.
Momenta's IPO price was HK$295.6 per share. With a market cap exceeding HK$70 billion post-listing, it was the largest among the five companies debuting that day. The offering raised approximately HK$6.8 billion and attracted a "star-studded" lineup of 14 cornerstone investors, including top-tier international funds, leading strategic industrial investors like Mercedes-Benz and BYD, and major Chinese financial institutions.
The company has pioneered a "flywheel" strategy, integrating mass-produced advanced driver-assistance systems (ADAS) with its full-self-driving (L4) development. Data from over 1 million vehicles equipped with its systems fuels its AI models, enabling continuous improvement. This massive real-world data scale is a core competitive advantage.
In April, Momenta launched its self-developed R7 World Model for mass production, a foundational model designed to understand and predict physical world dynamics. The company positions itself not just as an automotive tech supplier, but as a platform-level Physical AI company. Its technology platform has the potential to expand beyond autonomous vehicles into areas like logistics and embodied AI.
Financially, Momenta's revenue grew from RMB 743 million in 2023 to RMB 2.413 billion in 2025, with licensing income surging 42-fold during this period. While still reporting adjusted losses, it is nearing breakeven. The company boasts partnerships with 24 global automakers, including 9 of the world's top 10, and holds a 65% market share in China's third-party urban NOA segment.
The listing marks a significant moment for Physical AI in global capital markets, reflecting strong investor confidence in Momenta's unique technology path and commercial execution.
