Introduction
In a coordinated move that has sent ripples through the sports and betting industries, unions representing professional athletes from the NBA, NFL, MLB, NHL, and MLS have formally requested the Commodity Futures Trading Commission (CFTC) to prohibit prediction market platforms from offering bets on player underperformance or injury. The unions argue that such wagers—often termed ‘unders’—expose players and their families to harassment and abuse, and they call for stronger regulatory oversight to protect athlete well-being.
What Are Prediction Markets and Why Do They Matter?
Prediction markets, such as those operated by Kalshi and Polymarket, allow users to trade contracts on the outcome of future events—ranging from election results to sports statistics. In recent years, these platforms have expanded into sports, enabling bets on specific player metrics like total points scored, yards gained, or even injuries. While over/under bets are common in traditional sportsbooks, prediction markets offer a more granular, event-specific approach that unions say crosses an ethical line.
The Unions’ Letter to the CFTC
The joint letter, submitted in response to the CFTC’s request for public comment on prediction market regulation, focuses on the need to ban “under” bets—wagers that a player will underperform or be injured. The unions argue that such bets incentivize harmful behavior and create an environment where athletes are targeted for abuse if they fail to meet betting thresholds. The letter specifically highlights the risks to families, as players may face threats or harassment tied to their performance or health.
Protecting Athletes from Harassment
The unions emphasized that “appropriate regulations” are essential to shield athletes from “abusive and harassing behavior.” They noted that when a player falls short of a betting line, angry bettors sometimes direct vitriol at the player or their loved ones. By eliminating the option to bet on underperformance, the unions hope to reduce the incentive for such behavior.
Why the Focus on ‘Unders’?
Unlike over bets, which reward strong performance, under bets create a direct financial interest in an athlete failing or getting hurt. The unions argue that this distorts the spirit of competition and places undue pressure on players. In extreme cases, it could even lead to threats of violence if a player’s injury affects a bettor’s wallet.
Industry Response and Broader Implications
Prediction market platforms like Kalshi and Polymarket have not yet publicly responded to the letter. However, the request could reshape how these markets operate. If the CFTC adopts the unions’ recommendation, it might set a precedent for other betting formats and expand the conversation around athlete welfare in the gambling era.
Potential Impact on Sports Integrity
Beyond protecting individuals, the unions argue that banning under bets would help maintain the integrity of professional sports. When financial markets are tied to player failure, it can erode public trust in the game’s fairness. The letter aligns with ongoing debates about the line between legitimate sports betting and harmful speculation.
What’s Next?
The CFTC is currently reviewing public comments before deciding on new rules for prediction markets. The unions’ plea adds weight to calls for tighter regulation, especially as sports betting becomes more prevalent across the United States. Lawmakers and advocacy groups will be watching closely.
In the meantime, players’ unions continue to lobby for measures that prioritize athlete safety over betting profits. As one union representative stated off the record, “We don’t want to ban all betting—we want to stop the kind that puts a price on a player’s failure or pain.”
Conclusion
The request from the NBA, NFL, MLB, NHL, and MLS player unions marks a significant moment in the evolving relationship between sports and betting. By asking the CFTC to ban under performance markets, these organizations are drawing a clear line: protecting athletes from harassment must take precedence over expanding betting options. The CFTC’s decision will have lasting consequences for how Americans gamble on sports and how leagues safeguard their players.
Frequently Asked Questions
What exactly are ‘under’ bets in prediction markets?
They are wagers that a specific player will fail to meet a certain statistical threshold—like scoring fewer than 10 points, or being injured during a game.
Why are sports unions against them?
Because they link financial gain to a player’s underperformance or injury, which can lead to abuse, harassment, and even threats against the athlete and their family.
Did the unions ask for a total ban on prediction markets?
No. The letter specifically targets “under” bets and calls for regulatory oversight, not a complete prohibition of prediction markets.
What is the CFTC’s role?
The Commodity Futures Trading Commission oversees derivatives markets, including certain prediction contracts. They are soliciting feedback before drafting new rules.
