Underdog has filed the first seven sports event-contract templates for UDX, the federally regulated exchange it acquired in March. The filings target an initial listing no later than July 17, moving Underdog closer to controlling its own contracts rather than relying exclusively on outside exchanges.
Key Takeaways
UDX self-certified seven sports contract templates with the CFTC on July 15.Filings target first contract listings no later than July 17.Underdog bought Aristotle’s exchange and clearing entities in March.The entity-outcome template permits contracts involving athletes, teams, match winners, tournament advancement, championships, rankings, and statistical thresholds. The filing also allows multiple entities to be combined using AND logic (where every condition must occur) or OR logic (where one qualifying outcome is sufficient). That structure could support parlay-like products, although UDX does not use the term “parlay” or identify a specific combined contract it plans to list.
The filings are self-certifications rather than affirmative CFTC approvals: UDX certified that the products comply with the Commodity Exchange Act and commission regulations, while the regulator’s database records them as “Certified.” A separate UDX rule amendment supporting request-for-quote functionality remains under a 10-day review, indicating that some planned exchange features may follow the first product listings.
The certifications move Underdog beyond merely displaying contracts supplied by other exchanges. Once UDX begins listing the products, the fantasy and sports gaming company will also control the regulated venue where at least part of its prediction-market inventory is created, traded, and settled.
