Kalshi partners with Mass General Brigham doctor on youth trading risks
Kalshi is working with a Mass General Brigham doctor to produce a parent guide on prediction-market risks. Young adults ages 18 to 21 traded billions on the platform, according to multiple social and local news reports. The guide aims to educate parents about warning signs of addiction risk and the effects on young brains. Kalshi allows users as young as 18, a lower threshold than most U.S. sportsbooks, which generally require bettors to be at least 21. The partnership emerges as prediction apps draw growing parental concern.
The parent guide is a preemptive reputation play while Kalshi battles state attorneys general in Arkansas, Ohio, Tennessee, Louisiana, and Utah. Griffin's suit in Arkansas already weaponizes consumer protection tools as evidence of gambling intent. A doctor-backed youth risk frame gives Kalshi a counter-narrative it can deploy in court and in the media.
But the partnership also spotlights the very vulnerability state enforcers exploit: an 18-year-old age floor that sits three years below typical sportsbook thresholds. Every billion in youth volume becomes potential ammunition for consumer protection claims. Kalshi must now balance growth against the optics of protecting young traders it cannot afford to lose.
