Prediction markets and sports betting apps are luring in teens. Here’s why experts are concerned

Polymarket and Kalshi are using memes to attract users as young as 18. When Rory McIlroy won the Masters for the second year in a row, Kalshi shared a photo of him on Instagram with the words, “Wait he’s goated.” When a video of NBA player Damian Lillard recovering from an injury circulated online, Kalshi’s main competitor Polymarket posted, “The league is cooked.”If you don’t know what either of those phrases mean, it’s because you may not be the target audience.The posts and hundreds of others like it are exposing younger people to prediction market platforms, where users can put money on the line for the outcomes of real-world events — or absurd ones like when the U.S. will confirm that aliens exist or whether Jesus Christ will return before 2027.Once on the platforms, companies keep users hooked with what they market as low-stakes, casual opportunities to make an easy buck, creating an environment that some say feels more like a game and less like a risky financial transaction with potentially harmful consequences. Indeed, recent academic research looking at 588 million trades on Polymarket found that profits were concentrated to just a very small group of top traders while the majority of users — 69% — lost money.Kalshi, Polymarket and some sports wagering platforms are available to users starting at 18, mirroring the minimum age requirement for investing in the stock market but younger than the age limit of 21 for gambling in most U.S. states. That three-year window is critical to cognitive development, according to some experts, who note that teens and young adults are more vulnerable to developing problematic gambling behavior and addiction than older adults.“The adults in the room are not taking the fact this is meant to be an adult activity seriously, so when adults don’t take it seriously, why would the kids?” said Dr. Timothy Fong, an addiction psychiatrist and the co-director of the UCLA Gambling Studies Program, who notes that the “velocity of gambling” combined with the “frictionless” access to it creates a dangerous slope for young people.Sen. Katie Britt, R-Ala., introduced legislation last week with Sen. Richard Blumenthal, D-Con., that would bar social media companies and advertisers from showing sports betting ads to minors. Blumenthal said sportsbooks and prediction markets are “treating young people like a gold rush, flooding the internet with advertisements and promotions to hook them on gambling when they’re young.”
