U.S. stock futures are flat as traders await results from Georgia runoff elections

U.S. stock futures were flat on Tuesday night as Wall Street kept an eye on two runoff elections in Georgia that will determine control of the Senate.

Dow Jones Industrial Average futures dipped 26 points, or 0.1%. S&P 500 also slipped 0.1%, and Nasdaq 100 futures rose marginally.

Republican Senators Kelly Loeffler and David Perdue are facing Democratic challengers Rev. Raphael Warnock and Jon Ossoff, respectively. If both Democrats win, that would make a 50-50 tie in the upper chamber, with Vice President-elect Kamala Harris as the tiebreaker vote to give the party control of the Senate. Both races were too close to call as the polls in the states closed at 7 p.m. ET, according to NBC News.
