ProphetX
The New Jersey sports betting exchange that surrendered its state gaming license to conquer federal derivatives law.
Vanderbilt classmates Dean Sisun and Jake Benzaquen founded Prophet Exchange in 2018 after studying European peer-to-peer exchanges like Betfair and wondering why American sports bettors were still forced to pay 10% bookmaker margins. Raising an initial $10 million from Ninja Global, Bellevue Unbound, and former Match.com CEO Sam Yagan, the duo spent four grueling years negotiating with state gaming authorities. On August 30, 2022, Prophet Exchange made history by launching in New Jersey as the first licensed peer-to-peer sports betting exchange in United States history. By matching retail bettors against each other, the platform guaranteed the best odds in the state, completely eliminating the vigorish.
However, the state-by-state regulatory model quickly proved to be a gilded cage that almost killed the company. Expanding state-by-state required paying millions in local licensing fees, securing brick-and-mortar casino partners, and geofencing liquidity within individual state borders—destroying the deep national order book required for a thriving exchange. By late 2023, while traditional sportsbooks burned hundreds of millions on promotional promos, Prophet Exchange found itself squeezed by razor-thin margins and isolated liquidity pools. Recognizing that state gaming laws were fundamentally hostile to financial exchange architecture, Sisun and Benzaquen executed a radical strategic pivot: they shut down the New Jersey betting app in mid-2024, rebranded to ProphetX, and transitioned entirely to federal CFTC event contract regulation.
The gamble paid off spectacularly in 2025 when ProphetX secured dual federal CFTC approval as a Designated Contract Market (DCM) and Derivatives Clearing Organization (DCO). By reframing sports outcomes as binary economic event contracts governed under the Commodity Exchange Act rather than state gambling statutes, ProphetX unlocked legal access to traders across 48 U.S. states. Supported by a $35 million Series B round in early 2026 led by Archetype and PointsBet co-founder Sam Swanell, ProphetX operates a high-frequency sports prediction exchange processing over $150 million in monthly contract volume, positioning its proprietary clearing infrastructure as the premier institutional venue for sports derivatives.
