Traders are weighing the impact of Democratic control of Congress and victories for several key governors in the 2026 U.S. midterm elections. The Democrats swept to victory and took control of Congress overnight. The Associated Press also predicts that Texas Democratic gubernatorial candidate Gina Hinojosa will defeat Republican incumbent Gov. Greg Abbott. Hinojosa pledged to suspend the construction of data centers in the key technology hub.
