Do you trust that regulated prediction markets improve the integrity of professional sports betting?

The NBA has officially designated Kalshi and Polymarket as its preferred prediction markets through new multi-year partnership agreements. These deals include provisions for oversight and information-sharing protocols to monitor league-related events.

Why it matters

The league is moving to implement integrity protections by channeling betting activity into a regulated environment. This approach allows the NBA to monitor suspicious patterns and maintain control over the types of markets offered on its games.

The NBA partnership follows a broader landscape where prediction markets currently operate across 50 U.S. states. Meanwhile, 12 states are actively involved in ongoing prediction market litigation.
