AI capex boom extends through 2027; infrastructure winners emerge

Investment in AI infrastructure shows no signs of slowing as major cloud providers, chip makers, and networking firms signal prolonged capex cycles extending well into 2027 and beyond. Nvidia continues to lead, but the opportunity set has broadened to include Broadcom (networking), Corning (fiber optics), and emerging infrastructure names like CoreWeave and Iren, which support cooling, optical, and data-center support services. These companies are reporting backlogs and order momentumThe empirical fact that winners keep winning over the medium term. that outpace near-term supply, creating a multi-layer capex play.

The narrative has evolved from pure compute-chip demand to a broader capital equipment cycle: optical interconnect (CPO), cooling systems, power delivery, and AI-specific data-center infrastructure are all experiencing accelerating orders. Corning's partnership with Nvidia and fiber-optic demand from data-center networking upgrades underscore the durability of this supercycle. JPMorgan and other analysts argue that memory chip prices and DRAM/NAND supply are likely to remain tight through 2027 due to sustained demand from AI training and inference workloads.

Critics worry about capex fatigue and the risk of oversupply if demand growth slows or if AI model efficiency gains reduce the need for constant new compute. However, the breadth of infrastructure orders and the multi-year timelines suggest that even a slowdown in growth rates would merely extend the cycle rather than end it abruptly. Consensus expects earnings growth for infrastructure plays to accelerate through 2026 and 2027 on back of elevated capital investment.

Geopolitical risk to Taiwan, supply-chain disruptions, and tariff policy remain tail risks that could compress margins and delay capex, but absent a major shock, the infrastructure supercycle is likely to remain intact.
