NEW YORK, June 18, 2026, 15:10 EDT – Corning Incorporated (GLW) saw its shares surge 10.3% to $193.45 in Thursday afternoon trading, adding $18.05 on the day, as investors piled into the stock amid growing enthusiasm for its role in artificial intelligence data center infrastructure. The move outpaced the broader U.S. market, with the S&P 500 tracking ETF SPY up about 0.8% and the Nasdaq-100 tracker QQQ gaining roughly 2.4%.
AI Data Center Focus Drives Demand
Investors are increasingly viewing Corning not merely as a mature specialty-glass manufacturer but as a key supplier to AI data centers, where its optical fiber and connectivity products are critical for moving large volumes of data between chips and servers. Investor's Business Daily recently highlighted Corning as an AI data center play, noting the stock had risen 106% in 2026.
In related optical and networking names, Marvell Technology (MRVL) advanced 11.6%, while Ciena (CIEN) fell 2.5% and Lumentum (LITE) lost 4.0% in afternoon trading.
Key Partnerships with Amazon and Nvidia
The rally follows two major corporate agreements. On June 8, Amazon (AMZN) signed a multibillion-dollar deal with Corning to boost U.S. production of optical fiber and connectivity products used in data centers. Amazon said the agreement would create 1,000 jobs at Corning facilities in North Carolina, with Amazon Web Services CEO Matt Garman describing the investments as "long-term."
Earlier, in May, Corning partnered with Nvidia (NVDA) to expand U.S. optical-connectivity capacity tenfold, increase domestic fiber capacity by more than 50%, and build three new plants in North Carolina and Texas. Nvidia CEO Jensen Huang called the AI infrastructure buildout "a once-in-a-generation opportunity."
Growth Targets and Financial Performance
Corning has set ambitious growth targets. At a May investor event, the company projected a $20 billion annualized sales run rate by the end of 2026, with internal plans for $30 billion by 2028 and $40 billion by 2030. CFO Ed Schlesinger said Corning would "share the risk" of investments through long-term customer agreements.
First-quarter results provided a strong foundation. Core sales, Corning's adjusted non-GAAP revenue measure, rose 18% to $4.35 billion, while core earnings per share climbed 30% to 70 cents. Optical Communications sales surged 36%, and management guided for second-quarter core sales of approximately $4.6 billion.
Risks and Valuation Concerns
Despite the positive momentum, risks remain. Reuters reported in April that slower electronics replacement cycles and cautious consumer spending continue to pressure Corning's non-optical businesses, while an extended maintenance shutdown at a solar wafer facility weighed on near-term outlook. Valuation is another concern: Google Finance shows a price-to-earnings ratio of about 92, and the lowest 12-month analyst target stands at $180, below Thursday afternoon's price.
U.S. markets will be closed Friday, June 19, for Juneteenth, adding urgency to Thursday's trading. The main test for Corning remains whether AI-related optical demand translates into sustained margins and cash flow as new capacity comes online.
