Head to head
Which venue is currently the cheaper side of the same player props, de-vigged and counted live.
Right now BeatVig prices 311 player props at both. Polymarket is the cheaper side 80% of the time (249 of 311), and DraftKings is cheaper on 58. This is the board as it stands at 31 Oct 12:16 ET, not an average over any period — BeatVig measures live prices and keeps no price history.
Polymarket's taker fee is a fraction of a percent, which in theory makes it the cheapest way to take a position anywhere on this site. In practice the constraint is liquidity: a thin order book can show a beautiful price with nothing behind it, while DraftKings will always take your bet at the number it posted. The comparison below shows where Polymarket is genuinely the better price on a DraftKings prop, and it is worth checking the size on the Polymarket side before acting on one.
Counted above: every prop Polymarket 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.

Free accounts see a 3-edge sample from below the top of the board. Premium unlocks every prop where Polymarket beats DraftKings, in every sport.
Go PremiumAcross the 311 player props priced at both venues right now, Polymarket is the cheaper side on 249 and DraftKings is cheaper on 58; the rest are priced identically at both. Neither venue is cheaper on everything, and this is a live count of the current boards rather than an average over time.
Every quote from both venues is converted to the implied probability of the same outcome, so a contract price and an American price become the same unit. The cheaper venue is the one implying the lower probability for the side you want.
Polymarket's taker fee is a fraction of a percent, which makes its headline quote very close to the all-in cost and often the cheapest of the exchanges in the middle of the price range.
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.
