Democratic midterm wins tighten curbs on US data-centre construction

Democratic victories in the US midterms have opened a new regulatory front in the artificial intelligence buildout. In more than 40 counties where restrictions on data-centre expansion were on the ballot, citizens voted for them; in a single county they voted against, according to a compilation by the data service provider Redbud Consulting reported by the Frankfurter Allgemeine Zeitung. The measures ranged from outright bans to caps on electricity consumption and construction conditions that limit where facilities can be sited. Chipmaker shares came under significant pressure the day after the vote, even as most equities rose.

The immediate mechanism is local political control. Democrats took the governorships of Texas and Ohio, and the governor-elect in Texas, Gina Hinojosa, has announced she will block new permits until protection laws and participation rights for local residents are in place. Roughly a quarter of the new US data-centre capacity planned through 2030 is due to be built in Texas, according to t3n.

Markets read the outcome as relief first and sectoral dispersion second. The S&P 500 rose 1.6 per cent, the Dow Jones gained 3.0 per cent to over 1,500 points — its strongest post-election session in more than 40 years — the Nasdaq 100 added 0.91 per cent and the DAX closed up 2.22 per cent, with results clear enough to be quickly recognised by President Donald Trump. Beneath that, the neocloud builders CoreWeave and Nebius, which finance data centres with debt, fell about 9 and 6 per cent. Amazon, Microsoft and Alphabet rose more than 6, more than 6 and over 3 per cent respectively, on the expectation that a brake on construction leaves more profit inside the companies. Nvidia and AMD were sold. Amazon, Microsoft and Alphabet plan combined data-centre spending of more than $740bn this year, and a Bloomberg index of the seven largest tech groups has lost 5.9 per cent since Meta opened the cloud earnings season on 21 October, leaving it up just 4.1 per cent year to date.

SpaceX closed down 3.8 per cent; the company and Tesla are both headquartered in Texas, and investors were reported to fear stricter rules on AI and satellite infrastructure as well as political headwind for a possible merger of the two, after Elon Musk donated $224m in Texas alone and at least $474m in total to the midterms. An announced Qualcomm deal for the Starlink Mobile ground network limited the fall. The step to watch is whether Texas withholds new permits pending the protection laws Hinojosa has demanded.
