Democrats won control of both the Senate and House of Representatives, scoring victories in Republican strongholds including the Texas and Georgia governorships. Markets moved fast. The 10-year US Treasury yield fell 4.7 basis points to 4.918%, the two-year dropped 3.7bps to 4.597%, the dollar weakened 0.5% against a basket of six major currencies, and spot gold jumped 3% to $4,046 an ounce. The initial equity reaction was sharp — Nasdaq futures dropped 2.4%, S&P 500 futures fell 1.4% — before both turned positive, with Dow futures up 0.4%. The market's core calculation is straightforward: divided government means less fiscal expansion, less borrowing, and potentially less AI capital expenditure. Oliver Faizallah of Raymond James put it plainly — the result makes further significant fiscal expansion harder to deliver through Congress, easing pressure on Treasury issuance. Prashant Newnaha at TD Securities called bonds the clear winner as markets put the AI trade on the chopping block. Texas and Georgia are the fulcrum. Those two states account for roughly a third of all AI datacentre spending and projects. Democrat Gina Hinojosa won the Texas governorship on a platform calling for an immediate moratorium on datacentre buildouts. Analyst Tapas Strickland of Moomoo ANZ warned that the pace of AI infrastructure rollout could slow quite markedly in Texas, cascading through the rest of the sector. CoreWeave and Nebius fell overnight, and shares of Amazon, Alphabet, Microsoft, and Meta all declined on Tradegate. Tesla and SpaceX dropped 4.5% to 5%. European markets read the signal differently, or at least found their own winners. The Stoxx 600 gained 0.6%, with bank stocks up 2.8%. Clean energy stocks surged — Vestas Wind Systems jumped 5%, Ørsted 7.4%, Nordex 6.5%. European defence stocks fell. The logic: a Democrat Congress is less likely to punish allied clean energy investment and more likely to restrain US military adventurism. The Federal Reserve complicates the picture. Deborah Cunningham of Federated Hermes noted the Fed likely wanted to hike in October but held off due to proximity to the election. With stubbornly high inflation and a strong labour market, a quarter-point hike in December remains on the table, which would push the fed funds target range to 4.00-4.25%. Divided government may cool fiscal spending, but it does not cool an already-hot economy. Christopher Hodge of Natixis raised an underappreciated wildcard: Trump's reaction. Trump personally selected many of the losing candidates and historically responds to bad news by changing the narrative. Hodge flagged rumours of a short and intense campaign in Iran as a potential distraction, and named Defence Secretary Pete Hegseth and Treasury Secretary Bessent as potential scapegoats. The political fallout within the administration may move markets more than the election results themselves. ING's Chris Turner summarized the medium-term view: a Democrat Congress is a mild dollar negative, both for the AI story and the prospect of prolonged government shutdowns from next summer. But before that, investors face a strong US economy and a Fed ready to tighten further. The election reshuffled the deck on fiscal policy and AI buildout; it did not change the macroeconomic fundamentals.
