A federal judge has issued a preliminary injunction that blocks Minnesota from enforcing its newly enacted prohibition on prediction markets, delivering a major win to platforms including Polymarket and Kalshi just days before the measure was set to take effect.U.S. Both Kalshi and Polymarket US hold such designations, placing their offerings under federal oversight rather than state gambling rules. The ruling maintains the status quo for users in Minnesota who currently access these platforms to trade on real-world events. For Polymarket and Kalshi, the injunction represents a critical affirmation of their ability to operate uniformly across state lines without facing immediate felony exposure in Minnesota. The case will proceed toward a final determination, but for now, the platforms remain free to continue serving Minnesota customers under existing federal rules.
