With one week before kickoff, the NFL demanded prediction markets like Polymarket and Kalshi prohibit offering "objectionable bets that threaten the integrity of our games." Audit real-world contracts across single-actor power, officiating discretion, leak timing windows, and regulatory exposure.
This market directly hinges on an on-field referee discretion flag with acute single-actor actionability. The NFL's letter to prediction platforms specifically targets micro-events that a single participant can alter without competitive defense.
