Sports betting is illegal in Guam under the territory's gambling laws outlined in Title 9, Chapter 64 of the Guam Code (1). Gambling is, by law, illegal on the island, with comprehensive restrictions that prohibit all forms of gambling activities including sports betting, casino games, and gaming machines throughout the U.S. territory.
The Federal Reserve's Regulation GG reinforces these restrictions by prohibiting financial institutions from processing payments for unlawful internet gambling activities in jurisdictions where gambling is prohibited, including Guam (2). Gaming regulations issued in 2019 have strengthened enforcement and include specific penalties for violations of gambling prohibitions.
"Guam slot machine casino gambling does not exist. Gaming regulations issued in 2019 have made gaming machines illegal and include penalties."
Despite repeated attempts by some elected officials to introduce gambling for economic reasons, voters in Guam have consistently rejected legalized gambling initiatives. The territory maintains strict adherence to its gambling prohibition, with law enforcement actively monitoring and preventing illegal gambling operations. Unlike many U.S. states that have legalized sports betting following the 2018 Supreme Court decision in Murphy v. NCAA, Guam has maintained its complete prohibition on all forms of gambling activities.
