Underdog has switched on its own federally licensed prediction exchange, turning the sports prediction-market and fantasy operator from a middleman into a fully integrated venue with end-to-end control over its markets.
The Key Takeaways
- Underdog's new exchange runs on the CFTC-licensed UDX platform it acquired via Aristotle Exchange in March 2026.
- The first filings self-certify seven sports event-contract templates covering baseball, basketball and broader outcome markets.
- The move mirrors DraftKings' DKeX launch as U.S. operators race to own their prediction-market infrastructure.
The launch follows Underdog's acquisition of Aristotle Exchange DCM, Inc. (UDX) and Aristotle Exchange DCO in March 2026 — a deal that handed the company Designated Contract Market and Derivatives Clearing Organization status under the Commodity Futures Trading Commission (CFTC). With that license stack in hand, Underdog no longer needs to route its markets through anyone else.
"Now with our own exchange, we're going to unlock so much for more sports fans. Prediction markets are largely about sports, and Underdog is the best at sports."
— Jeremy Levine, CEO and Co-Founder, Underdog
Vertical Integration and Market Control
Until now, Underdog offered prediction markets through outside venues such as Crypto.com and Kalshi. Owning its own exchange gives the company direct control over contract design, trading rules and settlement — cutting its reliance on third parties while keeping existing partnerships in place, and opening the door to faster product development and tighter financial oversight.
The exchange's opening filings, self-certified with the CFTC on July 15, include seven sports event-contract templates aimed at baseball, basketball and broader outcome-based markets. They span game-winner, winning-margin and total-score contracts, plus a catch-all template for individual athlete, team or event outcomes. Each contract carries a $1 notional value and trades between $0.001 and $0.999, with set position limits for participants and market makers.
The filings also allow multiple outcomes to be combined with AND/OR logic — effectively bundling results without invoking the word "parlay." Formal trading start dates are still pending, but the paperwork signals Underdog's intent to list contracts no later than July 17, 2026.
Industry Implications and Future Outlook
Underdog's move lands amid a wider push toward vertical integration across the U.S. prediction-market sector. DraftKings recently rolled out its own DKeX exchange, a sign that operators increasingly want to own both the economics of each transaction and their regulatory compliance.
Since September 2025, Underdog has processed close to $6.5 billion in notional prediction-market volume — third among U.S. operators and ahead of several established rivals. The company has also secured Futures Commission Merchant status, making it, by its own account, the first U.S. sports company with a complete federal license stack for prediction markets.
Levine framed the launch as a response to growing fan appetite for a wider spread of betting and prediction products. Underdog plans to extend the exchange beyond sports into cultural events and broader outcome markets, leaning on its daily-fantasy and sports-betting expertise to grow market share while staying inside CFTC requirements.
