About this operator

ProphetX is a US sports prediction exchange that applies a financial market structure: limit orders, a central orderbook, and market makers: to sports betting. Rather than a bookmaker setting fixed odds with built-in margin, ProphetX lets traders post bids and offers against each other. The result is tighter pricing on popular markets and a venue that rewards research and discipline over luck. ProphetX is particularly popular with sharp bettors who are limited or banned at traditional sportsbooks.

Frequently asked questions — ProphetX


What is ProphetX? +

ProphetX is a US sports prediction exchange that applies a financial market structure (limit orders, a central orderbook, and market makers) to sports betting. Rather than a bookmaker setting fixed odds, ProphetX lets traders post bids and offers and match against each other, resulting in tighter pricing on popular markets.

What fees does ProphetX charge? +

ProphetX charges a low exchange fee on matched bets rather than embedding margin into the odds. The exact fee schedule varies; ProphetX positions itself as significantly cheaper than traditional sportsbooks for active traders, especially sharp bettors who would otherwise face line restrictions at bookmakers.

How is ProphetX different from a sportsbook? +

Traditional sportsbooks price their own markets with vig built in and often restrict or ban winning accounts. ProphetX is an exchange where the platform itself is neutral; it only matches bets between users and takes a small fee. Sharp bettors are welcome and cannot be banned for winning, since ProphetX profits from activity volume rather than from bettors losing.

Is ProphetX regulated? +

ProphetX operates in US states with legal sports betting under state-level sports betting licences. It does not have a CFTC DCM designation. Its regulatory framework is state-based sports betting regulation rather than federal derivatives regulation.
