Summary
Minnesota lawmakers led by Gov. Tim Walz moved to bar prediction markets starting Aug. 1, targeting platforms such as Kalshi and Polymarket as the sector rapidly expands in the U.S.
The ban is driven by concerns that event contracts are vulnerable to market manipulation, insider trading and conflicts of interest, especially when traders may have direct knowledge of or influence over outcomes.
Those platforms let users buy binary contracts priced from $0 to $1, with prices treated as implied probabilities on events ranging from elections and sports to weather and commodity moves.
Supporters argue the markets can aggregate dispersed information better than pundits or some polls, citing their 2024 election signals and potential use in spotting supply-chain, inflation or geopolitical risks earlier.
