Corning Incorporated (GLW)

From glass maker to the AI data center's physical backbone

If you still think of Corning (GLW) as 'the Gorilla Glass company for iPhones,' that story is out of date. From late 2025 into mid-2026, Corning has been aggressively transforming from a legacy glass/display company into the critical 'physical layer' supplier for the AI data center buildout — fiber optic cable, connectors, and co-packaged optics that link thousands of GPUs inside hyperscaler data centers like Meta's and Amazon's. At the same time, its solar/polysilicon business (Hemlock) is re-accelerating on the side.

This is not a small story. From July 2025 to its peak on June 30, 2026, GLW stock surged as much as 257% in a single year, driven by the 'AI optics' narrative and passive index-fund flows after Corning was added to major FTSE Russell growth indexes. But after hitting an all-time high (ATH) of $271.78 on June 30, 2026, the stock cratered ~36% in about two weeks to roughly $154.61 (July 18, 2026) — a combination of an overheated valuation, notable insider selling, and early signs of a slowdown in the carrier/telecom segment. We dig deeper into the valuation question in the Valuation section below.
