Zhongji Innolight kicks off Hong Kong listing of up to $8B

The Hong Kong Exchange is about to get its biggest test of appetite for an AI-adjacent Chinese listing in years, and it is arriving through an optics company most readers have never heard of. Bloomberg reports that Zhongji Innolight, the Shenzhen-listed maker of high-speed optical transceivers, has started gauging institutional interest for a Hong Kong secondary listing that Bloomberg's approval coverage sizes at as much as $8 billion.

The reason a transceiver vendor commands numbers like that is the AI training run. Innolight sits inside Nvidia's data-center supply chain, and the reporting puts its 2025 global optical-interconnect revenue share at 21.2%, with its position in 1.6T modules, the ones threaded through next-generation Nvidia clusters, at roughly 50-70%. That translated into first-quarter 2026 revenue of 19.5 billion yuan, up 192.1% year on year, and net profit of 5.74 billion yuan. The Shenzhen stock has climbed about sixfold in a year.

The deal is being run by Goldman Sachs, CICC, Morgan Stanley and GF Securities, and Innolight already has sign-off from both the China Securities Regulatory Commission and the Hong Kong Stock Exchange. Management has said proceeds will go to 1.6T and 3.2T optical module R&D, global capacity expansion, and strategic acquisitions, with 3.2T volumes expected in 2027. At the top of the reported range, the deal clears Luxshare Precision's $3.1 billion July 6 raise to become Hong Kong's largest listing of 2026.

The honest caveat is that a lot of Innolight's story rides on one customer's spending plans, and the reporting does not spell out precise Nvidia revenue concentration, the price range for the eventual offering, or the cornerstone book. It is also worth registering that the target has been reset upward more than once, from a confidential $3 billion April filing to $5 billion, then $7 billion, and now the $8 billion top end Bloomberg carried on the approval print. That is momentum, and it is also a deal being sized to the moment.

For global funds that want a clean listed proxy on AI networking without going through mainland access rails, the vehicle they have been waiting for is about to exist.
