Scenarios
Kalshi and Polymarket balance-of-power odds, 10/24 (PredictionScout).
Blue Wave: D House, D Senate; 66%
- Policy: Democratic bills meet a veto; funding fights and oversight drive change.
- Do well: hospitals and Medicaid-focused managed care, water and environmental services, renewable-exposed utilities (CNBC, 10/5); consumer staples and alternative energy (Morningstar, 10/8). Financials and industrials face pressure (Morningstar, 10/8).
Gridlock: D House, R Senate; 24%
- Policy: little new law; health, defense and tech policy hold steady.
- Do well: healthcare franchise, defense, civil infrastructure, large-cap tech (CNBC, 10/5). Energy independence: desk view.
Red Wall: R House, R Senate; 8–9%
- Policy: reconciliation stays available; deregulation and faster permitting.
- Do well: AI and data-center buildout, traditional energy and nuclear, financials, defense and cybersecurity (CNBC, 10/5); banks, industrials, managed care, data-center REITs (Morningstar, 10/8). Immediate expensing, advanced manufacturing and strategic materials: desk view.
What would change the desk's mind

- Raters shift several Senate toss-ups toward Republicans.
- The generic-ballot lead narrows sharply.
