The AI Boom Impacts Unexpected Industries: Shortages and Debates

The AI infrastructure buildout is triggering supply shortages across industries with no direct connection to software or semiconductors. Wood Mackenzie forecasts a 304,000-tonne refined copper deficit in 2025 widening further in 2026, driven partly by AI campuses that consume 27 to 33 tonnes of copper per megawatt installed. Transformer lead times have stretched from six months to over two years, now cited as the single biggest cause of data center project delays, with nearly half of global data center completions scheduled for this year facing delays due to grid and power constraints. S&P Global warns of a 10 million metric ton cumulative copper shortfall by 2040, characterizing it as a "systemic risk" to the clean energy and AI transition.

The energy sector is bearing the largest indirect burden. Microsoft, Amazon, Google, and Meta are collectively deploying over $280 billion in capital expenditures for 2026, predominantly for AI infrastructure. Morgan Stanley estimates a 49-gigawatt U.S. data center power shortfall through 2028. This demand surge is reshaping the nuclear industry: Microsoft signed a 20-year, $16 billion deal to restart Three Mile Island, Google struck the first U.S. corporate small modular reactor fleet deal with Kairos Power, and Meta issued an RFP for one to four gigawatts of new nuclear capacity. The scramble for clean baseload power has re-rated uranium miners and independent power producers as unexpected AI infrastructure beneficiaries.

The industrial spillover extends into thermal management. Eaton acquired Boyd Thermal for $9.5 billion in March 2026 in the largest deal ever in liquid cooling, while Ecolab acquired CoolIT Systems and projects 20%-plus annual revenue growth in its data center cooling business. Meanwhile, the real estate and infrastructure sectors are absorbing $400 to $450 billion in projected global AI infrastructure spending by 2026, a 65% jump from 2024, with Equinix forming a $15 billion hyperscale joint venture and Digital Realty launching a $10 billion hyperscale fund with Blackstone. Investors are increasingly scanning copper miners, transformer manufacturers, and power developers as second-order AI plays with less crowded valuations than the semiconductor names already pricing in peak optimism.
