The Midterms Delivered a Big Shift. What Comes Next?

The 2026 midterms give Democrats control of Congress, creating policy gridlock alongside greater oversight and new risks for the AI buildout.

• Democrats are on track to gain 40 to 45 House seats and could hold a 56-44 Senate majority if their leads in Mississippi and Alaska hold, while presidential approval averaged 38% and independent voters favored Democrats 58% to 38%.
• Affordability shaped the vote as inflation stood near 3.7%, the Federal Reserve moved toward tighter policy, and September job growth reached only 29,000; Hispanic voters, Gen Z, and independents also shifted toward Democrats.
• President Trump retains veto power, while Democrats will control appropriations, investigations, committees, and Senate confirmations; drug pricing and housing offer possible areas for compromise, whereas oversight and funding disputes may dominate.
• The 2027 debt-ceiling debate could increase market volatility, with deficits expected to remain above 6%, although Treasury yields could decline if easing inflation outweighs fiscal concerns.
• Voters supported tighter restrictions in 40 of 41 data-center measures, and the Nasdaq Composite fell 5.52% on November 5 as investors reassessed permitting delays, electricity costs, water use, capital spending, and future AI returns.

Takeaway: Investors should expect a more constrained administration, higher uncertainty around fiscal and regulatory conflicts, and greater selectivity toward companies exposed to data-center development.
