Zhongji Innolight, a Chinese manufacturer of optical transceivers for AI data centers and cloud computing, priced its Hong Kong IPO at HK$980 per H share on July 28, raising HK$53.4 billion (US$6.8 billion), making it Hong Kong’s largest share sale so far this year and the biggest since Alibaba’s 2019 secondary listing [1, 2, 3]. The company sold 54.5 million shares in the offering [1, 4].
The IPO was the second-largest Asian listing in 2026, trailing only Chinese chipmaker CXMT's US$8.6 billion Shanghai debut in July, whose shares surged 466% on debut [1, 2, 5]. Zhongji’s listing drew strong interest from investors, with the retail tranche oversubscribed 16.8 times and international orders 9.7 times, signaling strong demand for the stock before trading began [3].
However, Zhongji’s shares slipped between about 2% and 4% on their Hong Kong debut on July 30, opening at HK$971 then trading lower to around HK$957-971 during the day. Intraday declines reached nearly 10% as part of a broader global selloff hitting AI hardware stocks amid concerns about valuations, weak demand, and competition in the sector [2, 6, 7, 5, 4]. The company’s Shenzhen-listed shares also dropped over 9% on the same day, reflecting jitters among investors [7, 4]. Kenny Ng of Everbright Securities International noted, "AI hardware stocks are experiencing a correction since Zhongji Innolight started its listing process in Hong Kong. Investors are worried about how long the rapid growth of AI companies can last" [4].
Zhongji Innolight is the world’s largest optical interconnect solution provider by revenue, holding a 21.2% share of the global market in 2025 according to CIC consulting [3]. The company posted impressive first-quarter 2026 results, with net profit nearly quadrupling to 6.32 billion yuan and revenue tripling to 19.5 billion yuan year-on-year, driven by strong demand for AI infrastructure. About 61.7% of the company’s revenue in Q1 came from the US market [1].
The firm plans to use proceeds from the IPO to fund research and development, expand global manufacturing capacity, upgrade its supply chain, pursue acquisitions, and support working capital needs [1, 3, 4].
Zhongji Innolight’s stock performance will be closely watched in the coming months as investor sentiment toward AI-related stocks remains volatile amid ongoing concerns about the sustainability of rapid growth in the sector.
