If current results hold, Democrats take the House and Senate — but this isn't a legislative wave. Trump still holds veto power, and Democrats won't have 60 votes to break a filibuster or two-thirds to override. What changes is agenda control: committee chairs, hearing calendars, oversight intensity.

Winners: Solar, wind, and grid infrastructure get a reprieve from rollbacks and could see transmission expansion prioritized — with data centers forced to pay more for grid upgrades. Regional banks might catch a bid on deposit-insurance reform talk. Consumer names could benefit if a credit-card rate cap passes, though that pressures card lenders and payments infrastructure.

Losers: Oil and gas face windfall-tax proposals and tighter offshore scrutiny. LNG and pipeline permitting could stall if Democrats won't hand Trump a win. Big banks get dragged into more hearings and investigations. AI and Big Tech see higher regulatory uncertainty — competition, privacy, platform rules all back on the table.

This isn't a policy revolution. It's a transfer of the microphone and the gavel. First trade: renewables and grid infrastructure. Longer-term trade: less policy certainty across energy, financials, and tech.
