No MLB props are priced by both Hard Rock Bet and ProphetX at this moment. Prices repopulate as each slate's boards open.
How they differ
Hard Rock Bet 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 Hard Rock Bet 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
- Hard Rock Bet
- Hard Rock Bet is a traditional sportsbook: it posts its own line and prices both sides with its margin included, taking the other side of your bet itself rather than matching you against another user.
- Hard Rock Bet's margin sits inside the two prices rather than arriving as a separate commission, so it is paid on every bet whether that bet wins or loses. How much of a given price is margin varies by market — convert both sides to implied probability and the amount they total above 100% is what the book is charging.
- Hard Rock Bet carries one of the deepest player-prop menus of any venue on this site, listing the full passing, rushing and receiving spread across the slate rather than only the headline markets.
- 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.
