Overtime Markets vs ProphetX

Overtime Markets was launched in 2022 by the Thales Core Council—a decentralized governance council elected by stakers of the Thales (later rebranded to OVER) protocol. Engineered as an on-chain, peer-to-contract sports betting protocol on Ethereum Layer-2 networks (Optimism and Arbitrum), Overtime eliminated traditional sportsbook frictions such as forced identity verification (KYC), account limits on winning traders, and centralized custody. Instead of matching order books or taking counterparty risk, Overtime utilizes an Automated Market Maker (AMM) architecture derived from binary option mechanics.

To establish fair market pricing without a centralized oddsmaker, Overtime routes real-time data feeds via Chainlink oracles that scrape benchmark odds from global market venues like Pinnacle. The protocol dynamically adjusts its odds using a dynamic "skew mechanism": when heavy capital flows onto one side of an outcome, the AMM automatically reduces payout odds for the backed side while boosting yields on the unbacked side. This incentivizes arbitrage traders to rebalance the protocol’s net exposure, protecting the vault liquidity pool from directional market risk.

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.
