Mobile and Online Sportsbook Platform Displacement
#1U.S. online sports betting handle has grown from near-zero in 2018 (post-PASPA repeal) to over $100 billion annually by 2024, with mobile/online now representing approximately 90%+ of total sports betting handle in states where both channels are legal. DraftKings, FanDuel, BetMGM, and Caesars have collectively spent billions on market acquisition, creating deeply entrenched digital habits in the bettor population. State-by-state legalization continues — each new state that legalizes sports betting predominantly launches as a mobile-first market, with physical sportsbook infrastructure playing a secondary, often mandatory-but-minimal role.
