Sports betting giant DraftKings has launched a proprietary prediction markets exchange called DKeX, entering a space dominated by Polymarket and Kalshi as the company reports $3.4 billion in annualized consumer volume.
DraftKings announced DKeX on Tuesday as a "vertically integrated foundation" for its predictions business. The exchange generated approximately $3.4 billion in annualized consumer volume and approximately $11.3 billion in annualized total trading volume for the week ended June 21, per the company's announcement, with the 2026 FIFA World Cup cited as a key demand driver. DKeX is integrated into DraftKings' existing Sports and Casino app and operates under a CFTC license through Railbird Technologies, which DraftKings previously acquired.
DraftKings first entered prediction markets in December 2025 and inked a partnership with Crypto.com to expand its event contract catalog. DKeX marks the company's move from third-party infrastructure to owning the full technology stack.
"The launch positions the Company to innovate more rapidly through greater ownership over content depth, operating economics, and the end-to-end customer experience," the company said.
The platform entered beta in mid-May; since then, more than 30% of customers have used combinations, a feature that bundles multiple event contracts into a single position. Event contracts are available in 18 states. The company expects continued growth into July as World Cup matches continue.
