Corning Inc. (康寧) : $GLW
- R&D and Intellectual Property: With a history dating back to 1851, Corning maintains a dominant patent portfolio in glass and ceramic science. Their Gorilla Glass controls approximately 70–80% of the mobile cover glass market, creating a near-monopoly position that competitors struggle to disrupt due to proprietary chemical-strengthening processes. （ 曆史悠久的獨角獸）
- High Switching Costs & "Keystone" Integration: Corning acts as a "keystone" supplier. For instance, ASML—the sole provider of EUV lithography machines—relies on Corning’s specialty optical systems and mirrors. In the telecommunications sector, their proprietary Contour fiber technology allows for higher fiber density in smaller conduits, making it the preferred standard for AI-driven data center expansions.
Capital Intensity and Scale: The manufacturing of high-purity glass substrates and optical fibers requires massive capital expenditure and specialized "know-how" that acts as a significant deterrent to new entrants.

我昨天建倉， 主要原因：
- 2026 年是玻璃基板商業化元年。
- 而康寧是全球唯一的玻璃基板核心供應商。獨角獸。
- 今年內已經有3 個 Hyperscalers (META, NVDA + another one I haven’t figured out the name yet, have injected billions into Corning as business partners.(see GLW’s last ER transcript)
Any thoughts?
