Midterms 2026: The Stakes Beyond the Ballot Box

The 2026 midterms are unlikely to reverse the forces shaping markets, but they could alter the pace of fiscal policy, AI infrastructure deployment and geopolitical fragmentation.

• Republicans hold narrow congressional majorities, with 218–214 seats in the House and a 53–47 Senate advantage; 16 of the 21 House toss-up races and five of six Senate toss-ups are Republican-held.
• The president's party has lost House seats in 20 of 22 midterm elections since 1938, making divided government the team's most likely outcome and major legislation less likely, although budget deadlines and the debt ceiling could still force compromise.
• Fiscal pressure should keep rates elevated and volatile: the government pays an average 3.5% interest rate on roughly $40 trillion of public debt, with debt service absorbing about 5% of real GDP.
• The team's review finds that political attention to data centers is not proportional to construction volume: Michigan and Wisconsin show political salience comparable to Virginia and Texas despite considerably less data-center activity; the score is subjective and based on news coverage.
• Bipartisan support for competing with China, securing supply chains and strengthening U.S. trade policy suggests the midterms may affect the pace rather than the direction of geopolitical fragmentation; tariffs could rise and differentiation across countries and asset classes could increase.

Takeaway: Investors should expect fiscal negotiations to generate rate volatility, local opposition to influence the geography and speed of AI buildout, and geopolitical fragmentation to support diversification and active management; the broader investment themes are expected to persist through 2027 and beyond.
