Wall Street ends higher after Democrats win Congress; data center stocks tumble
Investors bet split control will curb debt and regulation, while fears of tougher AI scrutiny sent data center shares lower.
- On Wednesday, November 4, 2026, Democrats secured control of the U.S. Senate and House, sending global equities higher as the Dow Jones Industrial Average climbed over 1,000 points in response to the midterm election results.
- Investors interpreted the resulting congressional gridlock as a safeguard against major fiscal stimulus, easing concerns about additional government borrowing. The 10-year Treasury yield fell to 4.89% from 4.95%, reflecting reduced fiscal risk.
- Markets rotated into renewable energy stocks while Tesla and SpaceX, companies linked to Elon Musk, declined sharply. Brent crude futures plunged 8.8% to $94.62 a barrel, reflecting investor bets the power shift could hasten the end of the Iran war.
- President Donald Trump retains veto authority over Democratic legislation, yet the party now controls committees and subpoena powers. Trump eased market uncertainty by publicly accepting the election results, signaling willingness to work with Democratic majorities.
- Historically, midterm gridlock yields an average 15% market gain over 12 months, though analysts anticipate continued volatility. Future focus remains on potential regulatory scrutiny of the AI sector and debt ceiling negotiations in 2027.
