Matched Betting
What is the "Matched Betting Value" listed above? This is the amount of profit that you can make from the sign-up offer through a technique called matched betting. In short, it is a mathematical approach to sports betting that guarantees profit by hedging your bets. This allows you to cover all possible outcomes and secure a profit no matter what happens in the game. This is different from gambling because there is no risk of losing. Learn more in our What Is Matched Betting guide.

Overview
ProphetX is a federally regulated prediction market and sports event contract exchange that allows users to trade sports outcomes through a peer-to-peer marketplace rather than against a traditional sportsbook. As a designated contract market regulated by the Commodity Futures Trading Commission (CFTC), ProphetX operates under the same regulatory framework that governs other U.S. prediction markets like Kalshi. Unlike traditional sportsbooks that build a margin (vig) into their odds, ProphetX matches buyers and sellers directly, allowing market participants to set prices and provide liquidity. ProphetX then charges a 2% commission on the winnings.
For DarkHorse Odds users, ProphetX serves as both a source of market pricing and a potential hedging venue. Its exchange model often creates opportunities to compare market prices against traditional sportsbooks, other prediction markets, and betting exchanges. Because ProphetX is regulated by the CFTC rather than state gaming regulators, it operates under a different legal and operational framework than sportsbooks such as DraftKings or FanDuel. The platform's peer-to-peer structure, transparent order book, and ability for users to act as either liquidity takers or liquidity providers make it a unique part of the modern U.S. sports trading ecosystem.

MLB House Rules
Each sportsbook has its own House Rules which determine how a bet is graded. These rules cover unlikely events, such as what happens to your bet when a game is canceled.
Usually, the different house rules across sportsbooks do not have an impact on matched betting. However, in Major League Baseball (MLB), there are notable exceptions. A simple example is when a game is postponed due to weather. Read our House Rules Comparison guide to learn more.
For MLB it is also important to understand what defines Action.
