New Wisconsin Bill Would Legalize Online Sports Betting

The Badger State has been a slow adopter of new national trends, but it will have a chance to change that in 2026.

A new bipartisan bill proposes to legalize online sports betting in Wisconsin using a tribal-run framework. The proposal would allow the state to create a gaming compact with local gaming tribes. It would be similar to the compact between Florida and the Seminole Tribe, with online sportsbook servers being hosted on tribal lands.

The bill’s sponsors include Republicans and Democrats from across the entire state, showing strong support for legalizing the industry. They argue that the state is missing out on tax revenue while illegal operators bring dangerous gambling options to residents.

“This legislation is an important step to bring Wisconsin in alignment with the majority of the country in regards to sports wagering," bill co-sponsor Kalan Haywood said in a statement. "For too long, illegal, offshore entities have profited from consumers through unregulated sports wagering, without generating revenue for local economies.”

If the proposal is passed, it would not automatically legalize sports betting. Instead, it would authorize the state to finalize a gaming compact with tribal gaming groups for approval from the Department of the Interior.

Where Does Online Betting Take Place?

The proposal to add online sports betting in Wisconsin comes at an interesting time. Sports prediction markets have taken center stage as the new industry continues to grow. This has led to a slew of legal battles across the US as states and tribes look to protect their sports betting interests.

In their proposal, Wisconsin confirms that it considers online sports betting to occur where the sportsbook’s servers are located. This tactic was used by Friday and stood up to legal challenges from the highest levels of state and federal courts. While this strategy could help Wisconsin fast-track sports betting, there is reason to believe it could do more harm than good.

Kalshi, a leading sports prediction operator, has been fighting lawsuits from tribal gaming groups. Those groups argue the operator is illegally allowing gambling on tribal lands, since customers can make transactions while inside those borders. However, the operator has pointed out that those transactions would be processed at servers outside of those lands, making it legal.

With both sides investing time and money in these legal battles, expect the US legal system to be compelled to clarify where online sports betting occurs.
