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.
- 2018 Exchange concept born at Vanderbilt Dean Sisun and Jake Benzaquen launch Prophet in November 2018 to replicate European peer-to-peer betting exchange liquidity in the newly legalized U.S. sports market. They raise a $3.3 million seed round in September 2020 to begin state compliance work.
- 2022 Historic New Jersey state exchange launch On August 30, 2022, Prophet Exchange officially launches in New Jersey via a market-access partnership with Harrah's Resort Atlantic City, becoming the first legal peer-to-peer sports exchange in the United States and offering zero-margin betting on NFL and college football.
- 2024 Surrenders NJ license and pivots to ProphetX Recognizing state-by-state liquidity fragmenting kills exchange economics, Prophet shuts down its New Jersey platform in May 2024. Rebranding as ProphetX, the founders file formal paperwork with the CFTC to transition from a state sports betting operator to a federal event contract exchange.
- 2025 CFTC grants dual DCM and DCO designations In October 2025, the CFTC grants ProphetX full approval as a Designated Contract Market and Derivatives Clearing Organization. The dual designation gives ProphetX full in-house exchange matching and clearing capabilities, bypassing third-party clearinghouses like Cantor Fitzgerald or ForecastEx.
- 2026 Nationwide 48-state rollout and $35M funding ProphetX launches nationwide event contract trading in early 2026 across 48 U.S. states. Backed by a $35 million Series B expansion round led by Archetype, the platform records over $150 million in monthly sports contract volume within six months of launch.
ProphetX is a federally regulated peer-to-peer sports prediction exchange. Instead of betting against a sportsbook house that charges an 8% to 10% margin, users on ProphetX buy and sell binary event contracts directly against other traders. Market prices fluctuate between $0.01 and $0.99 based on supply and demand, settling at $1.00 if the sporting outcome occurs.
ProphetX was founded in 2018 by Vanderbilt University graduates Dean Sisun (CEO) and Jake Benzaquen (COO). The company is privately held and backed by prominent venture capital firms and gaming executives, including Archetype, Ninja Global, Bellevue Unbound, former Match.com CEO Sam Yagan, and former PointsBet CEO Sam Swanell.
Yes, ProphetX is legally available across 48 U.S. states. Unlike traditional sportsbooks governed by state gambling commissions, ProphetX operates under federal oversight from the Commodity Futures Trading Commission (CFTC) as a Designated Contract Market (DCM) and Derivatives Clearing Organization (DCO), regulating its products as financial event contracts under the Commodity Exchange Act.
Traditional sportsbooks like DraftKings set fixed odds with built-in house edges and ban or restrict winning users. ProphetX functions as a financial order book where users set their own odds, trade in real time, and take long or short positions. Because ProphetX matches peer-to-peer orders without taking house inventory risk, successful traders are never limited.
Prophet launched as a state-regulated betting exchange in New Jersey in August 2022. However, state-by-state laws prevented sharing order book liquidity across state lines, crippling market depth. In mid-2024, management voluntarily surrendered its New Jersey state license to pursue federal CFTC event contract licensing, unlocking unified liquidity across 48 states.
ProphetX eliminates built-in sportsbook vigorish and instead charges a micro-fee (typically 1% to 2%) on net profits earned on winning event contract trades. The platform also generates revenue from institutional API integration fees for market makers, premium order routing subscriptions, and interest earned on customer cash deposits held in clearing accounts.
