US midterms could reshape data center rules and investment

A Democratic sweep in the US midterms would increase the likelihood of federal legislation requiring data centers to contribute more toward grid costs and improve environmental reporting. A divided Congress would leave less room for federal action, but the debate is expected to intensify through the 2028 presidential election.

Gubernatorial races could matter more for the pace of construction, particularly in Texas, Georgia, and Ohio. Coordinated policy tightening across the South and Midwest represents the main downside risk. Local opposition generally shifts projects elsewhere rather than halting them, and resistance softens when developments provide community benefits or supply their own power.

National security concerns and bipartisan lobbying are expected to constrain future regulation, leaving Oxford Economics’ baseline outlook unchanged despite the political backlash. Threatened moratoriums and stricter rules may already be accelerating construction into this year. Restrictions introduced after the midterms would not immediately end the GDP boost from AI capital spending, while a slower buildout would not necessarily harm the broader economy over the longer term.
