In the OSB (Online Sports Betting) markets of New Jersey, Pennsylvania, and Michigan, FanDuel, DraftKings, and BetMGM continue to dominate, holding a combined market share of 81% to 90%. The dominance of these three operators is deterring challengers from entering these states and instead focusing on other markets.

However, in the iCasino markets of these states, there is a more open field of play. The combined market share of FanDuel, DraftKings, and BetMGM in iCasino ranges from 67% to 79%. When including Caesars, the average market share increases to 73% in Pennsylvania, 78% in New Jersey, and 79% in Michigan.
