DraftKings IncPrediction markets Kalshi and Polymarket are siphoning market share with lower fees and less regulation, contributing to DraftKings' stock decline.
Prediction markets like Kalshi and Polymarket are siphoning market share from traditional sportsbooks, contributing to sharp stock declines for DraftKings and Flutter Entertainment. Flutter is down about 60% since January 1 and DraftKings fell about 30% over the same period. Kalshi saw more than $1.3 billion in estimated revenue from sports contracts, roughly 20% of DraftKings' revenue, while the overall prediction market sector reached $31.2 billion in notional volume in May, with Kalshi accounting for 58% of that flow and Polymarket for 28%. These peer-to-peer platforms operate as clearinghouses charging fees as low as 1.2%, compared to the 7% to 10% taken by traditional sportsbooks, and they are not subject to the same federal and state regulations. DraftKings and FanDuel still control 75% to 80% of the traditional sports betting market, but their growth has slowed, with Flutter projecting 12% growth for 2026 and DraftKings guiding over 10%, far below prior year-over-year increases.
