Voters in at least 29 jurisdictions approved bans or restrictions on data centre construction, and the backlash is now the central question for the artificial intelligence buildout. The midterm results, welcomed by the market on Wednesday, were reassessed on Thursday, when investors decided that a new Congress means slower approvals, tougher terms and higher costs for the companies building the infrastructure behind AI.
Why it matters
The scale of what is at stake is enormous. A report by ICICI Bank said the election outcome could put 141 gigawatts of planned data centre capacity at greater risk of policy restrictions, and Texas, Georgia and Ohio, which together hold nearly a third of the country operating and planned data centre capacity, all elected Democratic governors. A new Congress is expected to scrutinise data centre construction, semiconductor exports, competition and energy use.
The regulation fear that drove the selloff has not gone away, even after Friday rebound. The Philadelphia Semiconductor Index gained 4.2 percent on Friday, recovering about a third of Thursday 12.2 percent plunge, but the companies behind the index still face the same political landscape. The market read the election as a slower buildout, and it sold the companies that depend on it, and one day of buying does not change the politics.
What happens next
The disagreement underneath the bounce is really about timing. Goldman Sachs argued that technology giants may pull capital spending forward into 2027, rushing to build under current approval conditions before new policies take effect. Jefferies described the selloff as reactionary rather than a fundamental reset, driven by a collision of concerns rather than by a change in the underlying business. Morgan Stanley expects United States business investment to rise about 7 percent year on year in the fourth quarter of 2026 and 8 percent in 2027.
What happens next will be decided in statehouses and in Congress, not only in the market. If the new Congress moves quickly to restrict construction or tighten energy rules, the buildout will slow and the companies that depend on it will face a longer period of adjustment. If it moves slowly, the builders will race to pour concrete while they still can. Either way, the politics of the data centre is now as important as the technology inside it.
