S&P 500 futures gain slightly on AMD's strong earnings as traders await election results: Live updates

Stock futures gained Tuesday evening as strong results from chipmaker Advanced Micro Devices boosted sentiment and traders largely anticipated Democrats to win the House of Representatives — and possibly squeak out a majority in the Senate — as results of 2026 U.S. midterm elections begin rolling in. S&P 500 futures traded 0.2% higher, while Nasdaq-100 futures gained 0.5%. Futures tied to the Dow Jones Industrial Average were slightly lower. Advanced Micro Devices had the biggest influence over the market as futures trading began, with its shares surging double digits in post-market action.
