A new survey found that nearly 8 in 10 prediction market users say they lost money. The report covers platforms including Kalshi and Polymarket, which offer wagers on elections, weather, and other events. The article is an interactive feature; the body provides only the topline finding and platform names with no further methodology, sample size, or demographic detail.

The loss rate suggests prediction markets are functioning as negative-sum venues for most retail participants, which could draw regulatory scrutiny or dampen user acquisition if widely publicized.
