The October edition of our U.S. Sports Betting Market Monitor is now live. 3Q25 OSB net hold averaged 6.8%, above 3Q24’s 6.5% but below 2Q25’s record high, setting up a mixed quarter for operators. We highlight bet365’s NFL-season land-grab, Fanatics’ continued share ascent, and FanDuel’s sharper NGR erosion as the duopoly’s grip narrows. Elsewhere, DraftKings’ up-to-$250mm acquisition of Railbird positions it for entry into the CFTC-regulated prediction markets space—a potential fintech adjacency with material execution and regulatory risk. Also inside: our latest ROI map benchmarking promo efficiency and a BettorMetrics-driven analysis of live NFL trading performance by operator.
