NVIDIA Invests $4 Billion in Coherent and Lumentum to Power Next-Gen AI Data Centers

NVIDIA has announced a combined $4 billion investment in two leading photonics companies — Coherent and Lumentum — to accelerate the development of optical interconnect technology essential for scaling next-generation AI data centers.

Key Highlights

• $2 billion invested in Coherent through a multiyear, nonexclusive strategic agreement covering advanced laser and optical networking products
• $2 billion invested in Lumentum via the purchase of 2.87 million shares of new Series A Convertible Preferred Stock at $695.31 per share
• Both partnerships include multibillion-dollar purchase commitments and future capacity access rights
• Focus on U.S.-based manufacturing expansion for both companies

Why Optics Matter for AI

As AI models grow in size and complexity, the demand for ultrahigh-bandwidth, energy-efficient connectivity inside data centers has become a critical bottleneck. Traditional electrical interconnects are reaching their physical limits, making optical solutions — specifically silicon photonics — essential for the next phase of AI infrastructure.

Optical interconnects allow data to travel at the speed of light between processors, memory, and storage within AI factories, dramatically reducing latency and power consumption compared to copper-based alternatives.

Details of the Partnerships

Coherent Deal

The $2 billion investment in Coherent, a global photonics leader founded in 1971 and operating in over 20 countries, will fund the company's R&D and U.S.-based manufacturing expansion. NVIDIA and Coherent have maintained a 20-year relationship that this deal significantly deepens.

"This strategic relationship underscores Coherent's role as a key enabler of next-generation AI data center infrastructure," said Jim Anderson, Coherent CEO.

Lumentum Deal

NVIDIA is investing $2 billion in Lumentum Holdings to support R&D, future capacity, and operations as the company builds out new U.S.-based manufacturing capabilities. The nonexclusive agreement includes multibillion-dollar purchase commitments for advanced laser components.

Jensen Huang's Vision

NVIDIA CEO Jensen Huang framed the investments as fundamental to the future of computing:

"Computing has fundamentally changed. In the age of AI, software runs on intelligence with tokens generated in real time by AI factories for every interaction and every context. With Coherent, NVIDIA is pioneering next-generation silicon photonics to enable AI infrastructure at unprecedented scale, speed and energy efficiency."

Regarding Lumentum, Huang added: "Together with Lumentum, NVIDIA is advancing the world's most sophisticated silicon photonics to build the next generation of gigawatt-scale AI factories."

Impact on the Industry

These investments signal a major shift in how AI infrastructure companies are thinking about scaling. Rather than focusing solely on chip performance, NVIDIA is now investing heavily in the connectivity fabric that links everything together.

The emphasis on U.S.-based manufacturing also reflects growing geopolitical pressures to secure domestic supply chains for critical AI infrastructure components.

What's Next

Both partnerships are multiyear agreements, suggesting that the optical interconnect technology being developed will be integral to NVIDIA's upcoming hardware platforms beyond the current Vera Rubin architecture. As AI factories scale toward gigawatt-level power consumption, efficient optical networking will become as critical as the GPUs themselves.
