Democrats have secured control of both the US Senate and House of Representatives in the November 2026 midterms, with Senate Democrats leading 54-44 after flipping at least seven states, and the House standing at 253-155. However, neither chamber reached the two-thirds majority needed to override a presidential veto, limiting their ability to enact legislation against President Trump's opposition. Markets reacted sharply on Thursday: the S&P 500 dropped 4.36% to 7,353.73 points — its largest single-day decline since April 2025 — while the Nasdaq Composite fell 5.52% to 24,315 points, entering correction territory. Bitcoin declined 5.5% to $76,036 amid the broader risk-off move. QCP Capital noted that Democratic measures such as delays in data center approvals and reduced tax incentives could weigh on AI infrastructure stocks, though these proposals would face a presidential veto without a supermajority.
