Zhongji Innolight Slumps in Hong Kong Debut as Global AI Rally Loses Momentum

Zhongji Innolight, the Chinese AI component manufacturer founded by billionaire Wang Weixiu, dropped as much as 9.8% during its Hong Kong market debut on Thursday as global investors scaled back AI holdings amid mounting concerns that the sector has overheated.

The stock recovered some ground to close the session roughly 4% lower. Already listed in Shenzhen, the company raised HK$53.4 billion ($6.8 billion) earlier this month by offering 54.5 million shares at HK$980 each in Hong Kong.

The offering ranks as the largest in the Asian financial hub in years and stands as the second-largest listing in Asia for 2026, trailing only Chinese chipmaker CXMT’s $8.6 billion IPO, which also launched in July. According to its prospectus, Zhongji Innolight intends to allocate the proceeds toward research and development and global production expansion. Meanwhile, its Shenzhen-listed shares tumbled more than 9% on Thursday.

The company confronts growing headwinds as skepticism toward AI-related equities intensifies. Zhongji Innolight produces optical transceivers, a critical component for the global data center buildout. By transmitting data via optical signals rather than copper wiring, these devices deliver the ultra-high speeds necessary to train and deploy AI models.

“AI hardware stocks have been correcting since Zhongji Innolight initiated its Hong Kong listing process,” said Kenny Ng, a Hong Kong-based securities strategist at Everbright Securities International. “Investors are questioning the sustainability of the rapid growth trajectory for AI companies.”

Ng noted that the negative sentiment, pronounced in U.S. markets, has spilled over into Asia. Capital has retreated from AI-exposed sectors following July reports that Meta Platforms was considering leasing excess computing capacity from its data centers, fueling worries that the social media giant may have over-invested on the supply side.

Concerns over demand durability continue to mount. South Korean memory chip leader SK Hynix slid after reporting quarterly earnings Wednesday that missed lofty expectations, deepening a selloff across chipmakers. On the same day, Meta was forced to defend its AI spending plans as investors questioned the return on investment following the company’s disappointing revenue outlook for the third quarter.

For its part, Zhongji Innolight has been a primary beneficiary of the AI boom. Late last year, Chairman and CEO Liu Sheng entered the global billionaire ranks amid a stunning rally in the company’s Shenzhen shares. In the first quarter of 2026, revenue surged over 190% year-over-year to 19.5 billion yuan ($2.9 billion), while net profit jumped nearly 300% to 6.3 billion yuan, according to the prospectus. The firm derives nearly two-thirds of its revenue from the U.S., counting Google among its key customers.
