With less than a month until the 2026 midterm elections, Democrats are favored by foreign bettors to take control of the House and Senate.
Lee Phelps, a spokesperson for William Hill, told USA TODAY that Democrats are more heavily favored to win the House than they have ever been at this point in a midterm cycle, adding that “oddsmakers have no doubt” the party will win the House.
“Republicans have been on the verge of action for some time,” Phelps said, calling the action in the Senate “equally remarkable.”
“The Democrats started at 5/2, which equates to a 28% chance of winning the House, but have been reduced to 4/9, giving them an implied probability of around 69%,” Phelps added.
Phelps said the volume of betting markets, which U.S. bookmakers cannot legally offer, still weighs heavily in favor of Republicans winning the Senate, buoyed by bets made when they were favored to win the upper chamber. He noted that only 32% of Senate bets were in favor of Democrats.
“We took a number of Republican bets at prices between 1/3 and 8/13, so many clients may now be sitting on positions that seemed very strong at the time but are surprised by the dramatic market reversal,” Phelps said.
Democrats showed strength in Senate elections in states like Texas, Iowa and Kansas, which seemed unlikely before America’s war with Iran and the recent surge in diesel prices.
