Stock market futures in both Canada and the U.S. surged Wednesday after the U.S. midterm election yielded Democratic majorities in both houses of Congress. Investors parsed the potential impact on artificial intelligence, the defence and wind energy sectors, as well as Big Oil.
The results usher in a new era of congressional resistance to the agenda aggressively pursued by U.S. President Donald Trump. One overarching theme was that divided government might not be such a bad thing.
Markets generally prefer that control of Washington be split between Republicans and Democrats. That is seen as offering less risk of sweeping policy changes that could upend the economy.
“The magnitude of the gains for the Democrats in the midterms does not change too much for the near-term policy outlook, given the party still lacks a filibuster-proof majority in the Senate and President Trump has veto power to block legislation,” Stephen Brown of Capital Economics said in an analysis.
Some Asian markets briefly retreated amid concerns that the Democrats might slow the buildout of AI because of safety concerns and local resistance to data centres. Investors have questioned whether a major run-up in stock prices for artificial intelligence companies signals a bubble in the sector.
Dow Jones futures traded 1.4 per cent higher and S&P 500 futures gained one per cent. Nasdaq Composite futures rebounded from an earlier AI sell-off, gaining 0.54 per cent. Wind energy stocks rose. Defence stocks were largely in retreat on the possibility that the war in Iran will be dialed back.

On Bay Street, TSX futures pointed to a one per cent gain early Wednesday.
Much remains impossible to predict, since Trump retains executive authority over key areas such as defence, foreign policy and in some instances trade.
A downbeat forecast could be that “Trump is not now a lame duck, but an angry duck” who might restart tensions over tariffs and NATO allies’ levels of military spending, said Carsten Brzeski, global chief of macro at ING Bank.
An optimistic view, Brzeski said, is that Trump becomes “a tame duck … that he will slow down any disruptive efforts and that he will put more focus on trying to win the Nobel Peace Prize by ending the two big wars without big disruption, and on trade, nothing happens but a few words.”
