As part of the 2020 USA election, prop measures to legalize sports betting were on the ballot in Maryland, Louisiana and South Dakota. After being approved in all three States, the measures still require further action from each legislature. Legal land based and/or online sports betting will be available in each jurisdiction at some point in 2021.
On May 14, 2018, the United States Supreme Court overturned the 1992 Professional and Amateur Sports Protection Act. That led to sports betting being deemed legal and states across America now have land based and online sportsbooks. Prior to that, Nevada was the only state with a full slate of legal sports betting.
