DraftKings told investors on June 9 that its prediction markets business is scaling fast, and the market liked what it saw.
Key facts
- Combined monthly trading volume on Kalshi and Polymarket, the two biggest names, climbed from under $5 billion in September 2025 to about $24 billion in April 2026, according to a Pew Research Center
- The company's Form 8-K reported that May 2026 annualized consumer volume in its Predictions offering rose 24% month over month to $1.3 billion, while annualized total volume traded climbed 34%
- DraftKings CEO Jason Robins told investors the company intends to establish a leadership position in sports predictions before year-end, and the company has raised its estimate of the total market it
- Its CEO, Vlad Tenev, said over 12 billion contracts were traded on the platform in 2025 and predicted the business could eventually drive “trillions” in annual volume, while Deutsche Bank counted
Summary
01 DraftKings said its Predictions business reached a $3.1 billion annualized trading run rate after launching in December 2025. 02 The scale matters because prediction markets already trade far more than legal U.S. sportsbooks, and DraftKings shares rose on the news. 03 The open question is whether DraftKings can catch established rivals before legal fights and liquidity keep widening the gap. Those figures are enormous for a product line that's barely six months old, since DraftKings only launched Predictions in December 2025.
