Prediction market Polymarket has found itself in some controversy over its ongoing plans to issue injury-based certificates for NFL bets. After self-certifying two of them with the Commodity Futures Trading Commission (CFTC), it withdrew them without explanation.
This development has revived discussion about whether injury-based bets are appropriate, especially given the NFL’s stance on it. On top of this, industry watchers and players have debated the potential impact on players, the league, and fan engagement with the game.
Polymarket Walks Back on Its Plans
Polymarket, as a platform, allows users to bet on the outcome of various events, including who will win games. Naturally, these predictions are impacted by players’ injuries. Seeking to capitalize on this, Polymarket earlier announced plans to let users bet on how soon players would return to the field following injury.
Players sidelined by injury, such as Kansas City Chiefs’ Patrick Mahomes, are already subject to considerable public scrutiny, and the NFL has pushed back against this trend. It outright asked prediction markets not to offer such contracts, but Polymarket moved forward nonetheless.
As per the public registry, they filed both a general product class and one specifically related to whether Mahomes will make an appearance in the first week of the upcoming season. But just a day after the filings were made, Polymarket withdrew them without any public reason given.
What the Contracts Are Controversial
While there is certainly a lot of money to be made from this initiative, considering Polymarket’s profits in the last year, it has been hotly debated. Mostly, it boils down to privacy, ethics, and even the safety of players. If there is a financial incentive for a player to make or not make an appearance following an injury, they could be put at risk by those who want the latter.
Some people in possession of players’ sensitive medical information could also be incentivized to engage in insider trading. In fact, the CFTC’s proposed event-contract rules outline these risks to both player and public well-being.
But Polymarket appears to be one step ahead, responding to the criticism by claiming that coaches, doctors, and other people with access to such information would be banned from placing bets in the first place.
This makes the withdrawal of its own contracts even more curious. For now, Polymarket users are waiting to see if the contracts will be reinstated and if injury-focused bets will indeed become a reality.
