Investors seeking AI exposure have discovered greater returns in companies that build and maintain data centers rather than chip manufacturers. The Data Centre Seven group of industrial firms has surged dramatically, with Comfort Systems up 328% and Vertiv climbing 246% in the past year. This infrastructure-focused approach has delivered superior performance compared to Nvidia's 74% gain.

Caterpillar exemplifies this trend, with its energy business generating 40% of $14.2 billion in first-quarter revenue and growing at 22%. Management recently raised sales growth targets to 6-9% compounded between 2024 and 2030, though the stock trades at 36 times forward earnings - pricing in expectations well above current guidance.

Morgan Stanley upgraded Caterpillar to equal weight, modeling 12% growth in the energy business through 2030. The equity market's deep intertwining with the data center boom creates vulnerability if the growth narrative falters, as the impact would extend beyond tech companies to these industrial suppliers that now command premium valuations based on AI optimism.
