FanDuel and DraftKings continue to dominate the U.S. online sports betting and casino markets, securing a commanding lead over their competitors. Their strong market presence, innovative platforms, and aggressive expansion strategies have cemented their status as the top players in the industry.
As of early 2025, FanDuel holds an impressive 43% share of the online sports betting market, while DraftKings follows with 25%. Combined, they control nearly 70% of the industry, far outpacing their nearest rivals. Their dominance is further highlighted by their financial performance—FanDuel generated $5.78 billion in gross revenue from $50.7 billion in wagers in 2024, while DraftKings reported $4.67 billion in revenue from $49.4 billion in bets across 26 states.
Beyond sports betting, FanDuel and DraftKings have made significant strides in the online casino sector. FanDuel now commands 27.4% of the iGaming market, slightly ahead of DraftKings’ 26.1%. Their continued growth has come at the expense of competitors like BetMGM, whose market share has declined from 30% to 20.6% over the past few years, causing the gaming giant to lay off a substantial number of U.S. employees.
Both platforms offer a diverse selection of online slots, table games, and live dealer experiences, making them the go-to choices for players seeking a high-quality digital casino experience. FanDuel and DraftKings are often regarded as the best casino apps currently on the market, thanks to their seamless user interfaces, extensive game libraries, and top-tier promotions.
To maintain their leadership positions, FanDuel and DraftKings have aggressively expanded into new markets while enhancing their platforms. FanDuel operates in 23 states, offering both sports betting and casino gaming where permitted. DraftKings, with its presence in multiple jurisdictions, has also continued investing in product innovation and exclusive partnerships to attract new users.
Their dominance, however, is not unchallenged. BetMGM, Caesars Sportsbook, ESPN Bet, and Fanatics Sportsbook are all competing for market share. BetMGM, in particular, maintains a 14% stake in the online betting market, while ESPN Bet, backed by Disney and Penn Entertainment, is rapidly gaining traction. Despite this competition, FanDuel and DraftKings remain the clear market leaders.
Through strategic growth, user-friendly platforms, and aggressive marketing, FanDuel and DraftKings have solidified their positions as the top online sportsbook and casino operators in the U.S. Their market dominance shows no signs of waning, as they continue to set the standard for digital gaming innovation. As online gambling expands into more states, their influence is only expected to grow further.
