One of the sponsors of Wisconsin’s statewide sports wagering legislation is warning prediction markets could take over the sports wagering marketplace if state lawmakers don’t pass a law in the Assembly Wednesday allowing the state’s 11 tribes to offer online sports wagering in the state.

“If we leave a gray area in state law, national prediction platforms will fill it without our compact framework, Wisconsin oversight, or Wisconsin consumer safeguards,” wrote Rep. Tyler August, R-Walworth. “AB 601 does the opposite: it channels activity into a regulated, Wisconsin-based, compacted environment with clear jurisdiction and accountability. This protects consumers, respects tribal sovereignty, and keeps revenue tied to Wisconsin operations rather than flowing to unaligned national apps.”
