As of my knowledge cutoff date in early 2023, sports betting in Florida was a complex and evolving situation. The legal age to participate in sports betting in Florida was 21 years old, in line with the standard legal gambling age in many U.S. states.

However, it’s important to note that the status of sports betting in Florida has been subject to legal challenges and changes. The Seminole Tribe of Florida and the state had reached an agreement that was approved by the Florida Legislature and signed by the governor, but this agreement faced legal disputes.

To get the most current information on the legal status and age requirements for sports betting in Florida, you should check with the latest state laws or with the official regulatory bodies overseeing gambling in the state, as these can change due to new legislation or legal rulings.
