Head to head
Which venue is currently the cheaper side of the same player props, de-vigged and counted live.
Right now BeatVig prices 1,243 player props at both. Courtside is the cheaper side 5% of the time (69 of 1,243), and DraftKings is cheaper on 0. This is the board as it stands at 14 Nov 01:09 ET, not an average over any period — BeatVig measures live prices and keeps no price history.
Courtside and DraftKings are both sportsbooks: each posts its own line and keeps its margin inside the two prices rather than charging it separately. Which of them is cheaper is not a constant and is not something this page asserts: every prop Courtside and DraftKings 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.
Counted above: every prop Courtside prices lower than DraftKings. Listed below: the ones that also beat a de-vigged fair price, which is the stricter test and the only one worth acting on.

Courtside'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 Courtside is quoting right now — add both sides' implied probabilities together and the amount past 100% is the margin on that market.
DraftKings' margin is inside the price. You pay it on every bet you place, whether that bet wins or loses.
It is computed from the live board every time the page loads, so it reflects the prices both venues are showing at that moment rather than a snapshot taken on an earlier day.
