Kalshi has announced new tools to prevent minors from trading on the prediction market, but is resisting calls to block ages 18-20. The company will require all users to use facial recognition technology when opening the app, making it more difficult for kids to use family accounts to log in. It will also promote two-factor authentication and allow users to see if someone else has logged in using their information. The move comes amid growing concerns about young people engaging in harmful behavior on sportsbooks and prediction markets. However, Kalshi and other prediction markets are facing pressure from lawmakers to implement consumer protection measures. The NBA and the PGA Tour have called for prediction markets to increase their trading age to 21 to match American sportsbook and casinos.
