Online sports betting in the U.S. has grown significantly, with Americans wagering $147.9 billion in 2024. Over 95% of these bets were placed online, generating $13.1 billion in revenue. As of February 27, 2025, 32 states and Washington, D.C. have legalized online sports betting. Missouri has recently joined the list, legalizing online sports betting to take effect by the end of 2025. New York leads in sports betting revenue, earning $2.1 billion, followed by Illinois at $1.2 billion.
