Nvidia & Intel Bet Big on Optical AI Interconnects

CScale, a stealth startup building optical interconnects for AI data centers, has raised $145 million in a Series C round led by Nvidia and Intel Capital. The investment marks a rare alignment between two semiconductor rivals, suggesting both companies see potential in addressing AI’s networking bottlenecks.

The round brings CScale’s total funding to $188 million, according to reports. Optical interconnects—high-speed data links that use light instead of electrical signals—are seen as a possible solution for scaling AI workloads, where moving data efficiently between components can become a limiting factor. Some industry observers believe such technology could help reduce power consumption and latency in large-scale systems, though CScale’s specific approach remains unproven in commercial deployments.

This funding round stands out not just for its size but for its backers. Yet here, both are investing in the same startup, raising questions about whether this signals a temporary overlap in their strategies or a recognition that certain infrastructure challenges require collaboration. For Nvidia, an investment in optical interconnects could suggest an interest in diversifying its data center offerings. For Intel, it may represent an effort to stay relevant in AI infrastructure as its own hardware faces competition.

The timing of the investment follows recent moves by both companies in the AI space. Nvidia has expanded its focus beyond hardware, while Intel has sought to carve out a role in AI through alternative approaches. CScale’s work could fit into these broader trends, though neither company has publicly detailed how they plan to integrate the startup’s technology into their roadmaps.

For now, the funding is a notable milestone for CScale, which has attracted two of the industry’s biggest players without being absorbed by either. However, the real challenge lies ahead. Optical networking is a complex field, and established players in data center infrastructure have yet to cede ground. If CScale delivers on its promises, it could play a role in shaping how AI data centers evolve. If not, the investment may fade into the background of the ongoing competition between Nvidia and Intel.

What’s next? Observers will watch for signs of CScale’s progress in commercial deployments and whether its backers begin incorporating its technology into their own products. If Nvidia and Intel start positioning optical interconnects as a key part of AI infrastructure, it could indicate a shift in how these companies approach the broader challenges of scaling AI systems. For startups and investors, the message is that the AI stack is still evolving—and the most impactful innovations may lie in the less visible layers of the ecosystem.
