Sports owners bet big on Republicans. What does their defeat mean for US sports?

Democrats’ gains in the US midterm elections weaken Republican control in Washington, disappointing sports owners who spent heavily backing Republican candidates. The result could affect disputes over prediction markets, gambling rules and public funding for stadiums, though both parties have helped expand the sports betting industry.

Professional sports owners gave more than $100m to candidates and political groups this election cycle, according to the article; former Mavericks owner Miriam Adelson contributed at least $67m to Republican committees. The NFL has asked the Supreme Court to treat prediction markets as gambling under state law, citing $1.8bn in football-related trades on the season’s opening Sunday. Meanwhile, Democrats have supported legal sports betting in states including New Jersey, Illinois and New York, and Nebraska voters rejected online sports betting by 54% to 46%.
