DraftKings Self-Certifies Sports Event Contracts for New DKeX Platform
DraftKings has self-certified several sports event contract products with the CFTC, while revealing the name of its in-house platform.
DraftKings-owned Railbird Exchange has self-certified its first six sports event contracts with the Commodity Futures Trading Commission (CFTC), marking the first public reference to the “DKeX” branding for DraftKings’ in-house exchange platform.
The filings were submitted on May 22, with the contracts scheduled to be initially listed on May 27. Among the products self-certified were:
- GAMEWIN contracts: “Will [entity] win [time period] of [event]?”
- GAMESPREAD contracts: “Will [entity] record a score differential relative to [opponent] of [condition] [count] during [time period] of [event]?”
- ENTITYSTAT contracts: “Will [entity] record [condition] [count] [statistic] during [time period] of [event]?”
- ENTITYOUTPERFORM contracts: “Will [entity] outperform [opponent] in [metric] during [time period] of [event]?”
- ENTITYACHIEVEMENT contracts: “Will [entity] earn [achievement] during [time period] of [event]?”
- GAMEPROPERTY contracts: “Will [property] occur in [time period] of [event]?”
DraftKings acquired Railbird in October 2025 as part of its broader push into federally regulated prediction markets.
Railbird operates as a CFTC-registered designated contract market (DCM), allowing DraftKings to list and operate contracts directly through its own exchange infrastructure rather than relying on third-party exchanges.
Contracts Resemble Sportsbook Markets and Micro Bets
The contracts mirror some of the most popular bet types offered by traditional sportsbooks, including moneylines, spreads, player props, and live microbetting markets.
GAMEWIN contracts function effectively as moneyline wagers on whether a team or player wins a game or a segment of an event. GAMESPREAD resembles traditional spread betting, while ENTITYSTAT and ENTITYACHIEVEMENT contracts resemble player prop markets tied to statistical thresholds or achievements.
ENTITYOUTPERFORM resembles head-to-head matchup betting. Meanwhile, GAMEPROPERTY appears broad enough to cover markets tied to over/unders, scoring sequences, timing-based outcomes, and other in-game events not captured by the other contract categories.
Some of the filings also reference “time period” structures within games. That opens the door for contracts on parts of events in addition to final outcomes.
The filings suggest DraftKings may be positioning DKeX to support federally regulated microbetting-style products.
Unlike traditional pregame wagers, microbets are tied to short-duration events within games. Examples include the outcome of a drive, inning, possession, period, or other discrete sequence of play.
The filings follow comments earlier this month from DraftKings President of Operations, Paul Liberman. He said he expects “fast, dynamic” microbetting markets to eventually enter sports prediction markets.
Notably, the self-certified products do not appear to include “combos” or parlay-style products. DraftKings recently introduced Combos and a revised fee structure for its DraftKings Predictions platform.
DraftKings Pushes Deeper Into Prediction Markets
The filings represent DraftKings’ clearest step yet toward launching its own exchange infrastructure. Currently, DraftKings’ Predictions product offers contracts through Crypto.com and CME Group exchanges.
By operating contracts through DKeX, DraftKings could gain greater control over contract design, liquidity, pricing, market-making, and exchange-level economics rather than relying on third-party exchanges.
The move is central to DraftKings’ broader prediction market strategy. During its Q1 earnings call earlier this month, CEO Jason Robins described prediction markets as a strategic priority and an acquisition tool for users in non-sports betting states.
Once live, DKeX will likely be integrated into DraftKings’ “Super App”, combining sportsbook, iGaming, horse racing, and event contract products into a single platform.
As state regulators and the prediction market industry continue battling in court over whether sports-event contracts fall under CFTC oversight or state gambling laws, DraftKings is expanding deeper into the sector.
The industry recently received additional political support after President Donald Trump publicly endorsed prediction markets on social media, calling them a “new form of Financial Market.”
