Valencia-based iPronics raised $125M co-led by Maverick Silicon and Light Street Capital, with participation from Nvidia, to develop an optical circuit switch
Valencia, Spain-based startup iPronics said Tuesday that it has raised $125 million in venture capital with participation from Nvidia …
Context & Ripple Effects
Nvidia had already backed optical-interconnect specialist Ayar Labs in 2022, then committed capital to Marvell’s silicon-photonics work and to Lumentum and Coherent’s photonics R&D and manufacturing in 2026. The iPronics financing adds an optical-switching bet to that chain of investments, while Maverick Silicon brings a separate networking-hardware investment record through Ethernovia.
First-order effects
- iPronics gains $125 million to develop its optical circuit switch, with Maverick Silicon and Light Street Capital co-leading the financing and Nvidia participating.
- Nvidia broadens its investment exposure from photonic components and transmission technology into optical switching, without the article establishing a supply or product agreement.
Second-order effects
- Marvell, Lumentum and Coherent become part of a more crowded Nvidia-linked photonics investment landscape, spanning silicon-photonics development, component manufacturing and switching.
- Maverick Silicon’s participation places an additional networking-infrastructure company alongside its Ethernovia networking-chip investment, reinforcing investor attention on data-movement hardware rather than processors alone.
Third-order effects
- If these investments translate into deployable products, AI-infrastructure financing is likely to reach further into the network fabric, where optical links and switching determine how compute systems are assembled.
- Nvidia’s sequence of photonics investments— including its Marvell silicon-photonics partnership—points to a supply-chain strategy that spans multiple layers of high-speed data movement rather than a single component category.
The trend: AI infrastructure capital is moving beyond accelerators toward the optical interconnect and switching layers needed to move data among increasingly large compute systems.
