Wisconsin Gov. Tony Evers on Thursday signed legislation legalizing online sports betting, making Wisconsin the 33rd state to allow the practice.

Legal wagering is not expected to begin for several months, as the new law requires the state and Wisconsin’s 11 federally recognized tribes to negotiate updated gaming compacts before bets can be placed.

“The real work begins today,” Evers said in a statement. He added that all tribes must “work diligently — and together — to shape the future of sports betting in Wisconsin.”

Under the law, online sports betting platforms must be operated through infrastructure located on tribal lands, a system known as the “hub-and-spoke” model. A share of gambling revenue will continue to be returned to the state under existing tribal agreements.

Evers said the measure could help fund mental health and opioid crisis programs, calling it an opportunity “to support mental health programs and to combat the opioid crisis.”

Supporters say the law will keep betting revenue in Wisconsin, as many residents currently use offshore sportsbooks or cross into neighboring states such as Illinois to place legal wagers.
