Eoptolink Files for $5bn Hong Kong AI-Infrastructure Listing
Latest in Deep Tech
Eoptolink, a Chinese manufacturer of high-speed optical transceivers, has filed for a secondary listing in Hong Kong, aiming to raise up to $5 billion—surpassing the $3 billion it floated in April. Positioned as the unsung hero of the AI boom, Eoptolink provides the essential "picks and shovels" that power data centers for tech giants like Google, Microsoft, and Amazon.
The Unseen Heroes of AI
Eoptolink’s optical modules are crucial for connecting AI chips to data centers, enabling the rapid transfer of massive amounts of data during training and inference processes. With AI clusters scaling up, demand for these transceivers has skyrocketed. In 2025, Eoptolink reported approximately $3.7 billion in revenue and a staggering 236% increase in net profit, reaching around $1.4 billion.
Global Tech Trends
Eoptolink’s listing is part of a broader trend as Chinese tech companies seek new venues due to tightening barriers from the US and EU. Hong Kong has emerged as a prominent hub for AI-related listings, with names like Baidu’s chip unit targeting a $50 billion IPO. The city’s strategic location makes it a key node in the global chip trade, facilitating the flow of both funds and hardware.
Geopolitical Interdependence
Interestingly, Eoptolink’s business model highlights an unexpected interdependence between American AI and Chinese optics. While governments strive to decouple, optical components have thus far evaded export control battles. The company’s products are integral to major US tech companies’ operations, demonstrating a delicate balance in the global tech landscape.
Risks Ahead
However, as Eoptolink rides the AI capital expenditure (capex) wave, there’s a risk of overdependence on this boom. The success of its listing and future growth hinge on sustained demand for AI infrastructure, which may not be immune to economic shifts or regulatory changes.
