Sports betting law in Maryland
Maryland needed a constitutional amendment to allow sports betting, so lawmakers put the question on the November 2020 ballot and voters approved it by about two to one. HB 940 followed in 2021. It allows up to 60 online licenses, each good for a single app, plus several classes of retail license for casinos, racetracks, stadiums and smaller businesses.
Retail betting began on December 9, 2021 at the state's casinos. Mobile betting took another year because the Sports Wagering Application Review Commission was required to review applicants with racial, ethnic and gender diversity in mind. Seven apps launched on November 23, 2022, and more followed through 2023 and 2024. A few have left since, including PointsBet and SuperBook, while bet365 arrived in August 2025.
Maryland banned prop bets on individual college players in 2024. Online casino games are still not legal here; sports betting and registered fantasy contests are the only real-money online options the state regulator recognizes.
Maryland teams to bet on
Maryland has two NFL teams and a big-league ballclub, and Washington's NBA and NHL teams are a short drive away.
- Baltimore Ravens (NFL): Hired Jesse Minter as head coach in January 2026, replacing John Harbaugh after 18 seasons.
- Washington Commanders (NFL): Play in Landover, home of Fanatics' retail sportsbook. The team plans to move to a new stadium on the RFK site in Washington, targeted for 2030.
- Baltimore Orioles (MLB): Craig Albernaz took over as manager for the 2026 season, which ended 79-82.
- Maryland Terrapins (college): Big Ten school in College Park. Buzz Williams became men's basketball coach in April 2025.
- Navy Midshipmen (college): The Naval Academy's teams play in Annapolis. You can bet Navy games, but not props on its players.
- Preakness Stakes (horse racing): Ran at Laurel Park in 2026 while Pimlico Race Course is rebuilt.
