Corning Up Over Fivefold This Year. Single-Day 12% Surge Hits Record High, Nvidia Ties Become Core Growth Engine.

TradingKey - On May 6, the AI chip giant Nvidia and Corning officially announced a long-term strategic partnership to jointly upgrade domestic AI optical infrastructure manufacturing capacity in the U.S., building an underlying interconnect system for next-generation AI computing clusters.

This major collaboration quickly ignited enthusiasm in the capital markets. Following the announcement, Corning's stock price surged 12% in a single day, bringing its total market capitalization to $156.2 billion, while Nvidia's stock also closed nearly 6% higher. This partnership represents a powerful alliance between two companies deeply benefiting from the AI boom. Looking back at Corning's stock performance over the past twelve months, the company hit a low of $43 and a high of $195, representing an absolute gain of nearly fivefold.

At the heart of the market excitement is Corning's plan to build three new advanced manufacturing facilities in North Carolina and Texas, where all production lines will focus exclusively on supplying specialized AI optical technology products to Nvidia. According to a joint statement, the new plants are expected to create at least 3,000 jobs, while increasing Corning's domestic optical manufacturing capacity tenfold and boosting optical fiber production by more than 50%, effectively addressing the domestic manufacturing shortfall in the U.S. AI optical supply chain.

The two companies also disclosed financial details of the partnership. Nvidia has secured the right to invest up to $3.2 billion in Corning, which includes warrants to subscribe for 15 million shares of Corning stock at an exercise price of $180 per share. The remaining $500 million comes from pre-funded warrants for an additional 3 million shares.

The underlying logic behind Nvidia's massive bet on the optical sector stems from the increasingly prominent interconnect bottlenecks in the development of AI computing clusters. The training and operation of every large model rely on the collaborative computation of hundreds of thousands of GPUs within a data center. Efficient data transmission between GPUs, servers, and racks directly determines the performance ceiling of a computing cluster. In this data center ecosystem, often referred to as an "AI calculation factory," optical modules have always been the core hub for connecting computing resources and achieving optical-to-electrical signal conversion, becoming one of the hottest sectors in AI infrastructure expansion.

Reportedly, copper cabling has historically been the primary medium for short-distance data interconnects, offering advantages such as zero latency, high reliability, and low cost. Jensen Huang has also stated publicly that as long as physical distance permits, copper is the superior connection method. Inside Nvidia's GB200 NVL72 rack, 72 GPUs are connected via more than 5,000 copper cables, totaling 2 miles in length. However, as AI clusters scale to tens or even hundreds of thousands of cards, the inherent limitations of copper cabling are fully exposed: beyond distances of 3-5 meters, copper signals attenuate rapidly. Long-distance transmission not only requires thicker cables, leading to extreme wiring complexity, but also results in significant power loss.

These industry pain points have made optical fiber and optical modules standard components in AI data centers. Using photons as the carrier for data transmission, optical fiber can transmit signals up to 10 kilometers at 400G speeds with almost zero signal loss, and its power consumption for long-distance transmission is far lower than that of copper. As the medium for optical-to-electrical conversion, optical modules are indispensable core components of fiber-optic transmission. The explosion in demand for AI computing power has directly propelled the optical module industry into a high-growth phase.

This collaboration between Nvidia and Corning is not a simple supply chain procurement, but rather a key step taken by Nvidia toward its Co-Packaged Optics (CPO) technology roadmap. By deeply integrating Corning's fiber technology into the CPO ecosystem, the goal is ultimately to replace copper cabling in Nvidia's AI rack systems with glass fiber, completing a full-link optical upgrade from rack-to-rack to the chip level.

As early as the 2025 GTC conference, Jensen Huang clearly stated that CPO is a core, essential technology for AI infrastructure expansion. Corning plays an irreplaceable role in this technological roadmap. Reportedly, its optical communications segment is now its largest and fastest-growing core business, having provided millions of miles of fiber-optic cable for the AI data centers of major global tech giants over the years.

Wolfe Research today raised its price target for Corning stock by 27.8% to $230, while maintaining an "Outperform" rating. The firm expects the stock to undergo a valuation rerating as the effects of scale expansion and the upside potential of its data center business become clearer.

Citi analyst Asiya Merchant also recently stated that demand for Corning's products remains very strong, as evidenced by customers' clear commitments and investments in Corning's capacity expansion plans. Citi maintained its "Buy" rating on Corning.
