AI growth has turned ordinary industrial names into market leaders. Over 200 public firms tied to data‑centre supply chains have outpaced the MSCI World, which climbed more than 21 % in the year to June 9. The surge eclipses the tech sell‑off that rattled equity markets on Friday in the market cycle.

Key beneficiaries include Caterpillar, which now sells generators for data‑centres, and 150‑year‑old Hochtief, entering the Dax next month. Nucor credits AI demand for a “tsunami of earnings power,” while Ford’s shift to battery storage for data‑centres lifted its shares by 20 % in May in the quarter of the year 2026.

Capital outlays for AI hyperscalers are massive: Alphabet, Microsoft, Amazon, Meta and Oracle project $700bn in 2026 alone. Monthly US construction spend hit $50bn in April, and JLL forecasts global capacity to double to 200GW by 2030, underscoring the scale of the build‑out for the data centre industry in 2026.

While some question the longevity of this boom, industrial players remain bullish. Schneider Electric cites AI data‑centres as a core growth driver, and Siemens’ data‑centre division grew 40 % in 2025. The surge delivers a hefty capex stream that reshapes legacy firms into AI infrastructure leaders for the global tech sector.
