Long odds, heavy trading
Longshot wagers account for a substantial share of activity on Kalshi and Polymarket, according to Bloomberg reporting by Carolyn Silverman and Denitsa Tsekova, republished by CDC Gaming. The report describes customers repeatedly choosing unlikely outcomes despite the losses associated with those bets.
Around half of Kalshi’s trading volume involves wagers offering potential returns of at least 1,000%, according to the supplied summary of Bloomberg’s analysis. The story’s headline characterizes the longshots dominating trading on Kalshi and Polymarket as losing 98% of the time.
Trading activity versus forecasting value
The findings highlight a tension between how prediction markets are promoted and how some customers use them. According to Bloomberg, the platforms’ billionaire founders present them as tools that turn wagers into accurate forecasts, potentially informing decisions by businesses and investors. The reporting instead describes many customers as seeking the excitement of highly improbable bets on markets available 24/7.
CDC Gaming republished the analysis at 7:09 PM ET on Oct 11, 2026; the supplied story carries a publication time of 7:54 PM ET. The available excerpt does not provide the underlying methodology or explain precisely which wagers fall within the 98% loss figure, limiting how broadly that statistic can be interpreted.
What it means for prediction markets
- Volume is not necessarily evidence of forecasting quality. Heavy trading in longshots can reflect demand for large potential payouts rather than confidence that an outcome is likely.
- The platform figures are not interchangeable. The roughly half-of-volume finding is specifically about Kalshi; the supplied material does not give a corresponding percentage for Polymarket.
- Loss frequency needs context. Without the underlying prices, sample and methodology, the 98% figure alone cannot establish whether those contracts were accurately priced.
