(AsiaGameHub) – Kalshi has introduced new trading limitations designed to mitigate insider trading risks associated with political and sports contracts. The changes were announced on Monday, a time when prediction markets are grappling with legal scrutiny and renewed concerns about market integrity.
Good to Know
- Kalshi will prohibit political candidates from trading in markets related to their own campaigns.
- Athletes, referees, and other sports staff will be restricted from participating in specific sports markets relevant to their roles.
- Polymarket, another prediction market platform, also released revised insider trading guidelines on Monday.
Kalshi stated that the new restrictions are proactive measures that have been in the works for several months. However, the timing of the announcement attracted notice, as it came only hours after a bipartisan U.S. Senate bill was proposed to outlaw prediction market contracts for sports events.
Per the new policy, political candidates seeking office will be excluded from trading in markets connected to their own campaigns. Additionally, Kalshi is preventing individuals associated with college and professional sports—such as athletes, staff members, and referees—from trading in markets related to the leagues they are part of.
The company is implementing these changes amid mounting pressure on prediction markets from multiple fronts. Over a dozen states have ongoing lawsuits that question the legality of sports event contracts. Concurrently, atypical trading activity has sparked further doubts about the integrity of markets focused on political and global events.
Polymarket, a competing platform, also issued enhanced insider trading guidance on Monday. Collectively, these changes indicate that leading prediction market operators are working to strengthen their controls as legal and political pressures continue to grow.
Not all parties are satisfied with Kalshi’s tightened restrictions. Congresswoman Alexandria Ocasio-Cortez (AOC) argues that the measures are insufficient, noting that significant risks remain and that further restrictions are necessary beyond what has been put in place.
This is absolutely not enough.
Just on the policy piece alone, there are SO many individuals – staff, advisors, consultants, cabinet secretaries, spouses, and more – that can trade on insider information.
This is just a fig leaf to deflect from criticism. We need to do more. https://t.co/9arxK8KPF0
