Corning’s transformation from a legacy glassmaker into a linchpin of artificial-intelligence infrastructure reached a new milestone on Monday, as shares rocketed to an all-time high of €175.40 — a gain of more than 11%. The catalyst was a $500 million supply deal with Nvidia, under which the chip giant will receive components for its data centers and warrants for up to 15 million Corning shares. The jump puts the stock up 28% in just seven trading days and more than doubled from the start of the year.
The rally has been accompanied by a wave of analyst upgrades that underscore Corning’s newfound strategic importance. Bank of America placed the company on its exclusive “US 1” list of top investment ideas, while Citigroup and UBS raised their price targets to as high as $225. Roughly 77% of analysts now recommend buying the stock. The endorsement reflects confidence in Corning’s “Springboard” plan, which targets an annualized revenue run rate of $20 billion by the end of 2026 and $40 billion by 2030. Three new U.S. plants are set to decuple capacity for optical connectivity products, the segment that grew 36% in the first quarter.
Operating momentum supports the ambitious targets. In Q1, adjusted revenue climbed 18% year over year to $4.35 billion, driven by Optical Communications. Gross margins expanded by more than 200 basis points, helped by a shift toward higher-value fiber-optic cables for AI networks — offsetting weakness in the trucking sector. Earnings per share came in at $0.28 for the quarter, and the board declared a dividend of $0.28 per share for Q2 2026.
Should investors sell immediately? Or is it worth buying Corning?
Yet the euphoria has also triggered profit-taking among top executives. In the second week of May, senior managers sold Corning shares worth over $10 million. While such sales are often routine portfolio moves, the timing — at the height of the record run — has not gone unnoticed by market participants. The insider activity injects a note of caution into an otherwise bullish narrative.
With its capacity booked solid for years to come and AI-driven demand for high-bandwidth connectivity showing no sign of slowing, Corning is being revalued as a structural growth story rather than a cyclical supplier. The stock now trades at a significant premium to its 200-day average, but the long-term visibility provided by deals like the one with Nvidia suggests the market may still be pricing in only the early innings of the fiber-optic buildout.
