Prediction markets offer the lure of fast money. Young men say they like their odds.

Close to 40% of young men between 18 and 34 use prediction markets, according to an April survey from Navigator Research, a public opinion research organization. On Kalshi, one of the leading prediction markets in the U.S., roughly 3 million of the platform’s 4 million active users are male. Six in 10 of the platform’s total users are between the ages of 18 and 34.
