Nvidia is partnering with Corning in a significant deal that includes an investment of up to $3.2 billion and the establishment of three new U.S. manufacturing plants focused on optical fiber for AI infrastructure. These facilities will create over 3,000 jobs and boost Corning’s optical manufacturing capacity tenfold, with the aim of replacing traditional copper with more efficient glass fiber in Nvidia’s AI systems. This collaboration underscores the growing importance of advanced optical technologies for powering the accelerating artificial intelligence boom.
In a groundbreaking move poised to redefine the landscape of artificial intelligence infrastructure, Nvidia, the leading chipmaker fueling the AI revolution, has announced a significant partnership with glass manufacturing giant Corning. This monumental collaboration will see the establishment of three advanced manufacturing facilities across North Carolina and Texas, dedicated exclusively to producing optical technologies crucial for Nvidia's cutting-edge semiconductor operations.
These new factories are set to create at least 3,000 jobs, dramatically boosting Corning's U.S. optical manufacturing capacity by an impressive tenfold, as detailed in a joint press release on Wednesday. While the precise financial specifics of the multiyear agreement remain undisclosed, the deal grants Nvidia the strategic right to invest up to $3.2 billion in Corning. This includes warrants to acquire up to 15 million Corning shares at an exercise price of $180 per share, alongside a pre-funded warrant for an additional 3 million shares.
The announcement sent ripples through the stock market, with Corning shares surging 12% and Nvidia stock gaining nearly 6% on the news.
This strategic alliance brings together two pivotal infrastructure players whose fortunes have soared since the 2022 launch of OpenAI's ChatGPT, which ignited a massive wave of investment into new processors and systems essential for advanced AI models. While specific developments weren't fully detailed, it's widely anticipated that Nvidia is preparing to replace traditional copper wiring with Corning's advanced optical glass fibers in its AI rack-scale systems, a transformative integration known as co-packaged optics.
At Nvidia's GTC conference in 2025, CEO Jensen Huang underscored the critical role of co-packaged optics in the ongoing AI build-out. Corning CEO Wendell Weeks echoed this sentiment, stating, "What Nvidia is doing is nothing short of extraordinary, not just for the future of AI, but for the American advanced manufacturing workforce."
Corning, a 175-year-old company, has seen its stock price skyrocket over 300% in the past year, largely due to its swift pivot into the new economy. This includes a significant deal in January where Meta committed up to $6 billion to support Corning in expanding its optical cable plant in Hickory, North Carolina, a project expected to generate approximately 1,000 jobs.
Nvidia solidified its dominant position in the AI market much earlier, with its graphics processing units (GPUs) being indispensable for developing large language models and enabling tech giants like Alphabet and Meta to scale their data centers massively. While Nvidia's stock has surged roughly 14-fold in the last five years, recent trends show investors diversifying their AI infrastructure bets, also backing chipmakers like Intel and memory providers like Micron, in addition to Corning.
The industry has long anticipated Nvidia's widespread adoption of co-packaged optics, a technology promising vastly increased data transfer speeds and reduced energy consumption for demanding AI workloads. Corning, renowned for producing display glass for Apple's iPhone, maintains optical communications as its largest and fastest-growing business. Since pioneering optical fiber for long-range communication in 1970, Corning has supplied millions of miles of cables to connect AI data centers globally.
Replacing copper with light-speed connections
This partnership signals a shift where Corning's glass fiber could soon be integrated directly between chips, potentially replacing the 5,000 copper cables currently found within Nvidia's rack-scale systems, such as the Vera Rubin.
Fiber-optic cables, minute, flexible glass strands, transmit data as photons at significantly higher speeds and with greater energy efficiency compared to traditional copper wires. As Corning CEO Weeks explained in a January interview, "Moving photons is between five and 20 times lower power usage than moving electrons." Vlad Galabov of Omdia noted, "You're bringing the light conversion process right next to the computer chip... Less power is wasted because now you're traveling a few millimeters, which requires far less energy than traveling across the circuit board." He added that "Nvidia has pushed the entire ecosystem to innovate faster."
Optical fiber also minimizes signal loss, ensuring faster and more reliable communication across the hundreds of thousands of GPUs in a data center. Huang emphasized the broader impact, stating, "AI is driving the largest infrastructure buildout of our time — and a once-in-a-generation opportunity to reinvigorate American manufacturing and supply chains. Together with Corning, we are inventing the future of computing with advanced optical technologies — building the foundation for AI infrastructure where intelligence moves at the speed of light while advancing the proud tradition of Made in America."
Nvidia previously released two network switches in 2025 employing similar technologies, placing them in close proximity to primary AI chips. Competitors Broadcom and Marvell have introduced comparable products, with Intel also developing co-packaged optics solutions. In March, Nvidia made a $4 billion investment in Coherent and Lumentum, companies specializing in lasers and components vital for converting data between light and electrical signals, which are then transmitted via Corning's fiber-optic cables.
Weeks articulated his vision during an exclusive factory tour in January, stating he was collaborating with "all the different chip folks on glass core and how glass will be part of semiconductor packaging going forward." He elaborated, "As power becomes a bigger and bigger issue, fiber inevitably gets closer and closer to the compute. The distances will climb, and when those distances climb up, fiber optics become much more economical and much more power efficient."
Corning is hosting an investor day at the New York Stock Exchange on Wednesday, coinciding with its 175th-anniversary celebration where it will ring the closing bell.
