Right now BeatVig prices 27 NFL props at both. ProphetX is the cheaper side on 18 of them and FanDuel on 9. That is fewer than 30 comparable props, which is too small a sample to state as a percentage, so the counts are published on their own. This is the board as it stands at 01 Nov 23:42 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.

How each one charges
- ProphetX
- ProphetX is a betting exchange: users post the prices and you take the other side of someone else's bet instead of accepting a desk's number.
- 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.
- FanDuel prices a broad US player-prop menu across the major leagues.
In short
ProphetX and FanDuel currently price 27 NFL props in common, which is too few to state a reliable percentage yet. Right now the best price gap is Kalif Raymond Receptions: ProphetX pays +146 against FanDuel's +140.
