What the 2026 U.S. midterms mean for investors and boards

Voters handed Democrats control of both the House and the Senate on November 3, ending two years of unified Republican government in Washington. For Canadian and international investors, asset owners and boards with interests in the United States, the result changes who sets the agenda on trade, energy, financial services and technology, and how much the White House can do without Congress.

The analysis below comes from The Southern Group, our affiliate, with teams in Washington and in Florida, Georgia, South Carolina and North Carolina. We are sharing it because it covers both Congress and the state capitals. Their main findings:

• Congress changes hands. As of the morning of November 4, Democrats were projected to hold the House 258 to 177 and the Senate 55 to 45. The Southern Group calls the result “a serious blow that sharply slows the president’s agenda.” Expect oversight investigations from January, appropriations used as leverage, and a president who governs more by executive order.
• Tariffs come under pressure. Democrats will move to roll back President Trump’s tariffs and narrow his tariff authority. Any repeal still needs his signature, so spending bills are their more realistic lever.
• A debt ceiling fight in 2027. The government is on track to hit the debt limit again by mid-2027. As a must-pass bill, it will attract unrelated priorities and will be the first direct negotiation between congressional Democrats and the White House.
• Energy and finance. Democrats will try to restore the clean energy tax credits repealed in 2025 and examine how data centres are raising power costs. Crypto market structure legislation is likely dead.
• The Southeast moved too. Georgia elected Democrat Keisha Lance Bottoms governor, and Democrats flipped the state houses in Georgia and North Carolina on unofficial returns. Republicans lost every legislative supermajority on the ballot in the four states. In Georgia, Democrats now hold a 3-2 majority on the Public Service Commission, which sets Georgia Power’s rates and decides how much new generation is built to serve data centres.

Several races were still uncalled on November 4, and their page updates as results come in.
