Zhongji Innolight's $6.8bn Hong Kong Debut Broke Issue

Hong Kong's Biggest Listing Since Alibaba Broke Issue in the First Minute

Zhongji Innolight raised $6.8 billion selling the optics that connect AI clusters, then opened below its HK$980 offer price, fell as far as 10.2%, and closed down 2.04%. Its Shenzhen shares dropped 9.15% the same day.

Zhongji Innolight, the Chinese maker of 800G and 1.6T optical transceivers that link AI accelerators inside data centres, listed in Hong Kong on 30 July. It sold 54.5 million new H shares at HK$980, raising HK$53.41 billion gross — about US$6.81 billion, with net proceeds of HK$52.89 billion. That is Hong Kong's largest listing since Alibaba's in 2019, and Asia's second largest this year.

The tape

It never traded above the offer. The stock opened at HK$971, reached a high of HK$973, fell to a low of HK$880 — down 10.2% — and recovered to close at HK$960, off 2.04%. Most wire coverage published intraday figures around 4% or 8%; the closing move was 2.04%, and the near-10% break is the number that describes the session.

The fundamentals are not the problem

First-quarter revenue was RMB 19.5 billion, up 192%; net profit RMB 6.32 billion, up 274%. Customers include Nvidia, Google, Meta and Huawei, and Nomura expects the company to hold around 30% of the global AI-transceiver market. Roughly 33 cornerstone investors took about HK$27 billion, among them Temasek, the Abu Dhabi Investment Authority, BlackRock, JPMorgan Asset Management, Alibaba and Tencent.

The disclosure nobody led with

The company was blacklisted by the US Department of Defense in June 2026 over alleged military ties — and denies it in its own Hong Kong filing. 61.7% of first-quarter revenue came from US customers.

And the other listing

Its Shenzhen shares closed at RMB 864.00, down 9.15%, after falling 15.7% on 28 July. Proceeds go 35% to optical-interconnect R&D and 30% to adding 50 million modules of annual capacity over three years.

Why It Matters

A company growing revenue 192% with a third of the world's AI-transceiver market could not hold its offer price for a single minute. The AI supply chain is still compounding; the market's willingness to pay for it in late July was not.
