China's Zhongji Innolight rallies on Hong Kong listing nod

Zhongji Innolight shares rose on Monday after the Chinese optical transceiver maker received approval for a Hong Kong listing that could raise up to $8 billion, potentially making it the city's largest initial public offering (IPO) of 2026.

The company, which supplies optical transceivers used in artificial intelligence (AI) data centres, has begun gauging investor interest following the approval granted on Friday, according to Bloomberg. Details including the size and timing of the offering remain under discussion and could still change.

If completed at the expected size, the deal would surpass Luxshare Precision's $3.1 billion share sale earlier this month, becoming Hong Kong's biggest listing this year, according to LSEG data.

Shares of Zhongji Innolight climbed as much as 8% in early trading before trimming gains to trade about 4.7% higher. The company did not immediately respond to requests for comment.

Hong Kong IPO market regains momentum

The planned listing comes as Hong Kong experiences a resurgence in IPO activity, driven largely by Chinese technology and AI-related companies seeking fresh capital.

According to KPMG, the city's IPO market raised HK$209.9 billion through 85 new listings during the first half of 2026, marking its strongest first-half performance in five years.

The consultancy also noted that more than 500 IPO applications, including confidential filings, are currently in the pipeline, with technology companies expected to remain a major growth driver.

AI demand fuels investor interest

Zhongji Innolight manufactures high-speed optical transceivers, a key component that enables rapid data transmission inside AI servers and data centres. Growing global investment in AI infrastructure has boosted demand for such networking equipment, making companies in the sector increasingly attractive to investors.

The proposed Hong Kong listing reflects continued investor appetite for Chinese firms positioned within the AI supply chain, even as competition in the sector intensifies.
