After completing its investigation into the merger of Spreadex and Sporting Index, the UK's Competition and Markets Authority mandated that Spreadex sell Sporting Index in order to preserve competition in the online sports spread betting market. In contrast to traditional fixed-odds betting, sports spread betting lets users wager on a variety of sporting event outcomes, with possible gains and losses varying according to how accurate their predictions are. Spreadex and Sporting Index were the only two licensed providers in the market at the time.
