Key Takeaways
  • Signify’s Threat Matrix will monitor public social media for abuse, threats and harassment targeting athletes, coaches and sports personnel.
  • The new policy builds on three pillars which could lead to police action and fines.
  • Athletes and relevant personnel have often complained about harassment from sports betting and trading.

A Wednesday announcement confirmed that Signify’s proactive threat monitoring technology will be used to take action against Kalshi accountholders who harass, threaten, or attack athletes.

The platform generated $74.3 billion in notional trading volume over the last 30 days and a daily record $4.2 billion on Sunday. Roughly 70-90% of the platform’s overall trading volume is linked to sports, depending on the day and time of year. 

Professional and amateur athletes have faced increasing pressure and abuse since sports betting was legalized in 2018. With prediction markets adding another avenue for consumers to win or lose money through sports event contracts, Kalshi is taking a proactive approach. 

“No person shall intentionally or recklessly engage in conduct reasonably likely to cause emotional distress to a third-party in connection with trading activity,” Kalshi’s new rule, dated Oct. 13, states. “This includes, but is not limited to, any conduct or attempted conduct reasonably likely to bully, frighten, threaten, scare, coerce, harass, or intimidate any third party in connection with trading activity.”

The partnership includes three basic pillars. The first is proactive monitoring by Signify’s Threat Matrix, an AI-powered safety service that detects, analyzes, and reduces online harassment and threats.

The second is Kalshi’s participation in the Bad Actor Program, through which individuals who are found guilty of abusing athletes will have their accounts suspended or closed, face potential police action, and fines.

The third is a new rule for all users of Kalshi’s exchange, which prohibits abuse and threats directed toward athletes and individuals involved in sports events.

“Kalshi users identified as responsible for abusive or threatening behavior may face enforcement action, up to and including permanent account closure,” the company’s announcement of the partnership read. “Where appropriate, relevant evidence may also be shared with sports organizations and referred to law enforcement to support further action.”

Fighting a growing trend

Prediction markets are updated based on real-time market data and user sentiment. Every action within a game, whether it be a missed strike call, a clutch three-pointer, or a long pass to the end zone have immediate implications on trading markets. But with that type of attention comes frustration from individuals bearing the brunt of frustrated traders.

Leagues, coaches, and players have expressed frustration with interference from fans outside of usual bad-mouthing and spirited cheering. Many of those cries came after sports betting was legalized, and they have since expanded with prediction markets, which have support from the Commodity Futures Trading Commission.

“​​Athletes and coaches should be able to compete without facing abuse or threats simply because someone has a financial interest in the outcome of a sporting event,” said Kalshi Head of Enforcement Robert DeNault.

“But actions speak louder than words, and this partnership between Kalshi and Signify gives us another important tool to identify unacceptable behavior and take action against those responsible. We will use this tool alongside a new exchange rule that explicitly prohibits abuse or threats in connection with trading activity because we want to make clear that there are real consequences for anyone who crosses that line.”

The new harassment measures build on Kalshi’s efforts to preserve the integrity surrounding its trading hub. The platform already uses market controls to identify suspicious trading and prevents athletes, coaches, and relevant personnel from trading on their own sports markets.

Harassment and antagonization

While companies such as Kalshi are attempting to reduce harassment, it is still an ever-present battle for athletes.

A survey of 100 MLB athletes by The Athletic found that 81 had been confronted by sports bettors over lost wagers within the last year. American golfer Jordan Spieth said in June that “betting in golf is something that’s going to have to be tackled here soon,” because of how fans’ close proximity to athletes could impact their performances.

“Players can’t do anything off of a betting type of sponsorship, but the tournaments profit,” tennis star Jessica Pegula also said after Kalshi was unveiled as a sponsor of the U.S. Open. “We get a lot of negativity from… bettors. We get a lot of hate on social media, so it’s tough when you see that, and then [those companies] are a big sponsor behind the court.”
