In this 47-page report, which is exclusively available to Enterprise Tier subscribers, we use our proprietary methodology and UK testing group to test, score, and rank the performance of UK sports betting apps. In this round of testing, conducted in 4Q23, bet365 took top honors, with its app materially outperforming those of fellow podium placers Sky Bet and William Hill. Also of note, Flutter (parent of U.S. OSB leader FanDuel) had a strong showing, with three of its apps—Sky Bet, Paddy Power, and Betfair—in the top five of our 4Q23 rankings.
