JPMorgan Chase Reviews Staff Prediction Market Participation
JPMorgan is evaluating whether to ban or require disclosure for its 320,000 employees trading on Kalshi and Polymarket. The review follows suspected insider trading cases at Google (Gemini 3 launch) and DraftKings involving prediction market contracts.
This reveals a critical regulatory gap—no federal insider trading laws cover event contracts. When traditional finance starts treating prediction markets as seriously as stock trading, you know the space has arrived.

Minnesota Targets Sweepstakes Casinos with Sweeping Bill
Minnesota's Bill 4474 would ban dual-currency sweepstakes casinos and extend liability to payment processors, geo-location providers, and affiliates. This follows November 2025 cease-and-desist letters to 14 operators.
The payment processor liability angle is new and aggressive. If this model spreads, it could choke off sweepstakes casino infrastructure faster than state-by-state operator bans.

Kalshi Sues Arizona Gaming Regulators
Kalshi filed a federal lawsuit against Arizona, seeking to block enforcement action on sports event contracts. Arizona joins roughly a dozen states challenging Kalshi's CFTC-regulated prediction markets.
Courts are split—Tennessee and New Jersey sided with Kalshi while Ohio, Michigan, Maryland, and Nevada ruled against. This is headed to the Supreme Court, and the outcome will reshape the entire prediction market industry.
