In response to increasing scrutiny from lawmakers, Kalshi and Polymarket have announced significant changes to their trading rules to combat insider trading and manipulation. Kalshi revealed plans to block athletes and politicians from participating in markets they are connected to, while Polymarket has tightened its regulations to curb suspicious trading behaviors. Both platforms are implementing new integrity policies and frameworks backed by the CFTC to ensure compliance and restore public trust. Despite these efforts, political figures like Alexandria Ocasio-Cortez have criticized the measures as insufficient, highlighting the ongoing debate surrounding the integrity of prediction markets.
