The NFL sent a memo regarding prop betting in light of recent gambling scandals in the NBA and MLB. The goal is to provide insight into how the league intends to protect the integrity of the sport. The memo outlines the “corrosive effect” that prop betting can have on fan behavior and player safety.
The NFL has outlined the following prohibited wager categories in this memo:
The biggest takeaway here is the “Determinable by One Person in One Play” category because that relates to micro-betting. This is exactly the bet type that resulted in the MLB gambling scandal involving pitchers Emmanuel Clase and Luis Ortiz.
While MLB has introduced a $200 limit on micro-betting, the NFL has opted to prohibit this market altogether.
This shift signals that the league is prioritizing game integrity over the growth of in-play wagering. Micro-bets carry the highest integrity risk because a single athlete can manipulate the outcome without affecting the final result.
By drawing a hard line, the NFL is sending a message to sportsbooks and bettors that certain play-specific markets simply present too much vulnerability.
For sports bettors, this memo doesn’t change much. Most users target popular prop bets involving touchdowns, yards, and catches. Micro-bets like “result of first play” are less popular options.
If anything, it’s helpful for bettors because micro-bets are often totally random. Users mostly opt to wager on this market just to add some excitement to the game they’re watching. As such, removing this bet type could prevent players from losing money on an unpredictable market.
For the industry as a whole, the NFL’s public statement reflects its commitment to make sure that a scandal like the one seen in MLB and NBA does not happen again.
It’s also worth noting that this could impact how sportsbooks design and offer NFL markets moving forward. Operators that were planning to expand live betting offerings will now need to scale back or rework their NFL menu to stay compliant.
Some oddsmakers may shift their innovation focus toward drive-level or quarter-level props, which fall outside the banned categories but still allow for in-play engagement.
Sportsbook compliance teams could also face tighter oversight. The memo effectively places responsibility on operators to filter out prohibited markets before they ever appear on betting boards, meaning internal auditing and league communication will become more important.
