Did “prediction market” apps expose your child to illegal gambling?

Keller Rohrback Investigates Kalshi, Polymarket, and Underage Gambling Claims
kalshi polymarket illegal betting lawsuit
Jul 2, 2026

Did your child use Kalshi or Polymarket before turning 18? You may have legal rights.

The nationally-renowned law firm Keller Rohrback is investigating prediction market apps, including Kalshi and Polymarket, regarding potential violations of underage gambling laws, among protections.

Apps like Kalshi and Polymarket allow users to “trade” on the outcomes of future events, such as elections, sports, financial markets, or current events, by buying and selling contracts tied to specific predictions. Prices fluctuate based on market sentiment, giving participants the opportunity to profit if their predictions are correct. If this feels like gambling to you or your loved ones, you are not alone.

Many parents and advocates are concerned that these platforms expose minors to gambling-like behavior despite the well-documented risks of gambling addiction among young people.

Gambling can be highly addictive, particularly for children and teens whose brains are still developing, increasing the risk of compulsive behavior, financial harm, and long-term mental health and emotional consequences.

If you or your child used Kalshi, Polymarket, or a similar prediction market platform while under 18, Keller Rohrback wants to hear from you. Contact us today for a free, confidential case evaluation. Call us at (800) 776-6044, email us at [email protected], or complete the form on this page.
