TLDR DraftKings-owned Railbird Exchange has self-certified six sports event contract types with the CFTC for its new DKeX platform The contracts cover game wins, spreads, player stats, outperformance, achievements, and game properties These contracts closely mirror traditional sportsbook markets like moneylines, spreads, and player props DKeX will give DraftKings direct control over its own exchange infrastructure instead of relying on third-party exchanges CEO Jason Robins called prediction markets a strategic priority during the company’s Q1 earnings call DraftKings Files Six Contract Types Through Railbird Exchange
DraftKings has taken a major step toward building its own prediction market exchange. The company’s subsidiary, Railbird Exchange, filed six self-certified sports event contracts with the Commodity Futures Trading Commission on May 22.
The contracts were scheduled to be listed starting May 27. This marks the first public use of the “DKeX” branding for the company’s in-house exchange platform.
The six contract types include GAMEWIN, GAMESPREAD, ENTITYSTAT, ENTITYOUTPERFORM, ENTITYACHIEVEMENT, and GAMEPROPERTY. Each one covers a different type of sports outcome.
GAMEWIN contracts ask whether a team or player will win a game or segment. GAMESPREAD covers score differentials. ENTITYSTAT and ENTITYACHIEVEMENT focus on player performance and milestones.
ENTITYOUTPERFORM handles head-to-head matchup comparisons. GAMEPROPERTY appears to cover broader in-game events like scoring sequences and timing-based outcomes.
These products closely resemble the types of bets already offered by traditional sportsbooks. Moneylines, spreads, player props, and live microbetting markets all have counterparts in the new contract filings.
DraftKings acquired Railbird in October 2025 as part of its push into federally regulated prediction markets. Railbird operates as a CFTC-registered designated contract market.
