Overview
- The league told teams it is engaging state regulators and betting partners to limit or prohibit certain NFL prop markets.
- It reiterated four prohibited categories: inherently objectionable topics, officiating-related wagers, outcomes determinable by one person in one play, and pre-determined events.
- The guidance classifies prediction markets such as Kalshi and Polymarket as prohibited gambling activity for NFL personnel.
- Reporters say major U.S. sportsbooks largely did not offer the flagged NFL props, so immediate changes to betting menus are not expected.
- The move comes after federal cases in MLB and the NBA involving alleged prop manipulation and insider schemes, while some analysts dismiss the NFL step as largely symbolic.
