Three AI infrastructure plays in focus as data center demand rises

The article frames three established large-cap stocks as beneficiaries of AI infrastructure demand at a moment when macroeconomic tailwinds—cooling inflation and softer rate expectations—are supporting interest in capital-intensive tech hardware. Each company occupies a distinct but complementary role in the data center supply chain: Corning provides the high-bandwidth optical connectivity that GenAI workloads depend on, Eaton supplies the power and backup systems that keep infrastructure running, and Amphenol manufactures the connectors and cabling that physically wire the buildout.

What distinguishes this analysis from mainstream AI stock coverage is its focus on the "plumbing"—the enabling layer rather than processors themselves. The article notes that these three stocks emerged from a broader screener identifying 31 U.S.-listed companies with similar data center and AI infrastructure profiles, suggesting this theme extends beyond these three picks. However, a critical tension runs through the coverage: each company is flagged as already pricing in strong AI tailwinds. Corning's valuation already reflects strong AI expectations; Eaton carries a rich valuation with a high bar for future delivery; Amphenol's premium price tag suggests expectations are elevated. The implicit warning is that while the underlying demand drivers appear sound, the equity upside may be constrained by how much of the growth story the current stock prices already assume.
