Nvidia invests $4 billion into photonics to keep AI chips ahead of the curve

Nvidia just dropped $4 billion on two companies you might not know

You’ve probably heard of Nvidia, the giant behind most of the AI tech in the news. But to keep building the brains of artificial intelligence, they need some very specific parts, and they’re willing to spend big to get them. Just recently, Nvidia announced it’s investing a total of $4 billion into two American companies, Lumentum and Coherent.

It’s a huge vote of confidence in the future of AI and the smaller, specialized businesses that make it all possible. The market clearly agreed, after the announcement, Coherent’s stock jumped over 15%, and Lumentum surged nearly 12%.

So, who are Lumentum and Coherent?

Lumentum and Coherent might not be household names like Nvidia, but in the world of high-tech gear, they’re rock stars. Both companies specialize in something called photonics, which involves creating and controlling light for high-performance applications.

In simple terms, they build the components that create and control the light beams carrying data through fiber-optic cables. NVIDIA is putting $2 billion into each of them to help build more of this crucial tech right here in the USA, with Lumentum planning a new fabrication facility and Coherent expanding its domestic manufacturing footprint.

Why is Nvidia throwing billions at light?

AI systems still rely heavily on electrical connections, especially copper for short-reach links, but optical interconnects are becoming increasingly important for networking inside large AI data centers.

NVIDIA has said optical interconnect technology and package integration are critical to scaling AI factories, particularly as those systems demand more bandwidth, efficiency, and resiliency.

The secret sauce inside your future gadgets

The technology from these companies isn’t just for giant data centers you’ll never see. It’s the foundation for all the smart tech we use every day. When you ask your phone a question or use a filter on a photo, that information is being processed somewhere far away.

As these AI tools get smarter and more common, the need for this super-fast, light-based technology explodes. NVIDIA is making sure the pipes are wide enough to handle all that future data. JPMorgan analysts noted that these deals highlight the importance of securing capacity for the optical components that make our connected world possible.

AI factories are the new big thing

NVIDIA’s CEO, Jensen Huang, talks about building AI factories. Think of them less like a regular data center and more like a giant, high-tech factory that produces intelligence. These facilities need to be connected in super-smart ways, with millions of chips all talking to each other at the speed of light.

The deals with Lumentum and Coherent are all about providing the high-tech conveyor belts inside these AI factories. Huang put it this way: together with Lumentum, Nvidia is advancing the world’s most sophisticated silicon photonics to build the next generation of gigawatt-scale AI factories.

This isn’t their first rodeo together

NVIDIA isn’t just throwing money at strangers. They’ve been working with these companies for a long time. Coherent, for example, has had a relationship with Nvidia for 20 years. These new deals deepen those friendships significantly.

It’s like moving from being a regular customer to becoming a major partner in the business. By investing billions, Nvidia is saying, We trust you, and we want to grow and build the future side-by-side.” Jim Anderson, CEO of Coherent, expressed pride in expanding this 20-year relationship with Nvidia to help build the AI data centers of tomorrow.

Fun fact: The agreements with both companies are nonexclusive and include multibillion-dollar purchase commitments, with the Lumentum deal running through 2030. These commitments are actually on top of previously disclosed orders, showing just how massive Nvidia’s appetite for optical components has become.

What’s in it for Lumentum and Coherent?

Besides a massive pile of cash, this deal gives these companies something even more valuable: certainty. With Nvidia committing to buy billions of dollars’ worth of their components, they can confidently invest in new factories and hire more people.

Lumentum has already announced it will build a brand-new fabrication facility in the U.S. This means more high-tech jobs and more cutting-edge manufacturing happening on American soil, all thanks to the demand from the AI boom. Michael Hurlston, CEO of Lumentum, stated that they are investing in a new fabrication facility to increase capacity and accelerate innovation.

Wall Street gave a thumbs-up

When the news hit, investors were clearly excited. Shares of Lumentum jumped almost 12%, and Coherent’s stock soared by about 15%. That kind of jump shows that the market believes this is a smart move.

It signals to everyone watching that the future of AI hardware is shifting toward this light-based technology, and these two companies are now right in the middle of all the action. Rosenblatt analyst Mike Genovese rates both stocks as buys, calling for significant upside from their current prices.

Building a backup plan for the future

You might wonder why Nvidia invested in two companies doing similar things. It’s smart planning. If you rely on just one supplier for a critical part and something goes wrong, like a fire at a factory or a supply chain issue, your whole business can stop.

By investing in both Lumentum and Coherent, Nvidia is creating a strong backup plan. Both partnerships are structured as nonexclusive agreements. This ensures they have multiple sources for the advanced lasers and optical parts they need, making their supply chain more resilient and secure against unexpected problems.

From copper wires to beams of light

For decades, our electronics have relied on copper wires to send signals. But we’re hitting the physical limits of copper. At super-high speeds, the signals just get garbled, and the wires heat up too much. This is where a technology called co-packaged optics, or CPO, comes into play.

This move to photonics is a fundamental shift in how computers are built. NVIDIA announced in 2025 that it would fully adopt CPO technology in AI data centers by 2026, integrating silicon photonics directly into its network switches. It’s like moving from a two-lane country road to a massive information superhighway made of light.

What the bosses are saying

Jensen Huang, the leader of Nvidia, is known for his big ideas. He said, “Computing has fundamentally changed.” He describes a world where software runs on intelligence that’s generated in real-time by these new AI factories.

The CEOs of Lumentum and Coherent are just as excited. They talk about this partnership as a way to accelerate innovation and build the AI data centers of the future. The leaders of all three companies see this as a historic moment for the tech industry, with Huang emphasizing that AI is driving the largest computing infrastructure buildout in history.

A long-term bet on our tech future

This $4 billion investment isn’t about a quick profit next quarter. It’s a long-term bet on how we will all use technology in the years to come. Some analysts don’t expect to see a sizable market in this new photonics technology until at least 2029.

As AI becomes a bigger part of our lives, in our cars, our homes, and our workplaces, the need for this powerful and efficient computing will only grow. NVIDIA is making sure the foundation for that future is solid. By betting big on American photonics, they’re helping to build the invisible infrastructure that will power the next generation of innovation for all of us.
