All Legal US Sports Betting Operators
The regulated sports betting market in the United States is a vast and dynamic ecosystem featuring over 50 unique licensed online operators. This proliferation is a direct result of the 2018 Supreme Court decision that empowered individual states to legalize and regulate wagering. Currently, 38 states plus Washington, D.C., offer some form of legal sports betting.
The industry is divided between a handful of national giants that command over of the market and numerous regional or niche operators. While the major brands offer wide accessibility and robust features, all licensed operators must adhere to strict state regulations, including age verification (typically 21+) and geolocation technology. Users should always play on licensed platforms, as offshore sites lack US consumer protection and carry significant risks.
The Dominant National Brands
A small group of operators has leveraged prior experience in Daily Fantasy Sports (DFS) or retail casinos to achieve massive market saturation and brand dominance.
These national operators are constantly competing to attract customers with large welcome bonuses, such as Bet , Get in bonus bets or up to in first bet offers.

Market Dynamics and Future Trends
The US sports betting market is characterized by intense competition, ongoing consolidation, and a heavy focus on technology.
Market Share and Consolidation
FanDuel and DraftKings remain the clear market leaders, controlling over of the online gross gaming revenue combined. Their dominance stems from established user bases from their prior DFS businesses and aggressive marketing. Consolidation is a major trend, highlighted by Fanatics’ acquisition of PointsBet’s US assets throughout 2023 and 2024, signaling new players entering through acquisitions rather than organic growth.
Mobile-First Focus
Nearly all betting in the US is conducted via mobile apps, which typically achieve high ratings (4.8/5 for FanDuel, 4.7/5 for DraftKings). Success is driven by features such as:
- Same-Game Parlays (SGPs): Popularized by FanDuel and now a standard offering.
- Live Streaming: Offered by bet365 and others, allowing users to watch and bet in the same app.
- Unique Rewards: Caesars links its betting with its massive hotel rewards program, while Fanatics offers FanCash redeemable for merchandise.
State Accessibility (Excluding Retail-Only)
As of late 2025, 32 states plus D.C. offer statewide mobile or online sports betting, with Missouri launching its online market in December 2024. However, major states like California and Texas remain without legal sports betting options. The industry is currently eyeing potential future expansions into states like Georgia and Alabama.
