Right now BeatVig prices 35 NFL props at both. BetOnline is the cheaper side 8% of the time (3 of 35), and ProphetX is cheaper on 31. This is the board as it stands at 02 Nov 16:12 ET, not an average over any period — BeatVig measures live prices and keeps no price history.
How they differ
BetOnline is a sportsbook: it posts its own line and keeps its margin inside the two prices. ProphetX is an exchange: traders set the price between themselves and the fee sits outside it. Which of them is cheaper is not a constant and is not something this page asserts: every prop BetOnline and ProphetX 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
- BetOnline
- BetOnline is a sportsbook: it posts its own line and prices both sides itself, taking the other side of the bet rather than matching two users against each other.
- BetOnline's margin sits inside the two prices rather than arriving as a separate charge, so it is paid on every bet whether that bet wins or loses. The hold measured below is what that costs on the props BetOnline is quoting right now — add both sides' implied probabilities together and the amount past 100% is the margin on that market.
- BeatVig has not written a coverage note for BetOnline. What it quotes right now is measured directly from the board below rather than described from memory.
- 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.
In short
Right now BetOnline is the cheaper price on 8% of the 35 NFL props both venues price, measured live off the current boards.
