Polymarket is consolidating the high-stakes sports flow that sportsbooks and newer entrants like Kalshi and Robinhood's Rothera test are competing for.

Kalshi sues Minnesota to block first US felony ban on prediction markets

Kalshi must now litigate on two fronts—federal court against Minnesota's felony statute and Dane County against Wisconsin's parallel injunction push—draining legal resources ahead of the August 1 effective date.

Polymarket severs Santos contract as DOJ probes alleged Kalshi insider trades

Polymarket must now prove its surveillance systems flagged or could have detected Santos-style self-dealing, or face the same co-defendant exposure the CFTC and DOJ are already applying to exchanges that miss insider abuse.
