Underdog launches UDX, its own CFTC-regulated exchange for sports contracts
Underdog has launched UDX, its own CFTC-regulated prediction market exchange. The company migrated its prediction markets in-house after acquiring Aristotle Exchange DCM and Aristotle Exchange DCO in March 2026, giving it designated contract market, derivatives clearing organization, and futures commission merchant registrations. UDX self-certified its first sports event contracts covering baseball and basketball on July 15, 2026, and submitted seven contracts for CFTC certification. Previously, some Underdog customer accounts routed trades through Kalshi or Crypto.com's Derivatives North platform.
Underdog's in-house move strips revenue from Kalshi and Crypto.com at a vulnerable moment. Both platforms face rising state legal pressure and a bipartisan Senate bill that would ban sports event contracts outright. Underdog no longer pays routing fees or shares customer data with partners. It now controls its own spreads, liquidity, and compliance posture.
The shift follows DraftKings' June launch of DKeX, proving that fantasy-sports platforms can build full regulatory stacks. Smaller rivals still dependent on white-label rails must now choose between expensive acquisitions or shrinking margins. The NFL season will test whether UDX can match established venues on liquidity. A thin spread through football would confirm the vertical-integration model and accelerate industry consolidation.
