Right now BeatVig prices 466 NBA props at both. ProphetX is the cheaper side 35% of the time (167 of 466), and FanDuel is cheaper on 252. This is the board as it stands at 01 Nov 23:40 ET, not an average over any period — BeatVig measures live prices and keeps no price history.
How they differ
ProphetX is an exchange: traders set the price between themselves and the fee sits outside it. FanDuel is a sportsbook: it posts its own line and keeps its margin inside the two prices. Which of them is cheaper is not a constant and is not something this page asserts: every prop ProphetX and FanDuel both price right now is converted to the implied probability of the same outcome and counted below, so the answer moves with the two boards rather than with the date this page was written.

- ProphetX

- ProphetX charges commission on net winnings rather than embedding a margin, so the cost is explicit and only applies when you win.
- ProphetX is live in a limited set of states and its liquidity concentrates on the biggest games and the most-traded player markets.
- FanDuel
- FanDuel is a traditional sportsbook: it sets the line and prices both sides with its margin included rather than matching you against another bettor.
- FanDuel's margin is inside the price, so it is charged on every bet regardless of the result.
