No MLB props are priced at both Polymarket and DraftKings at this moment. Prices repopulate as each slate's boards open.
How they differ
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.
Where Polymarket is cheaper
Polymarket is not currently the better price on any MLB props both venues list.
How each one charges
- Polymarket
- Polymarket is an order-book market: the price is whatever two traders agree on, and a share that settles at $1 quotes as a probability directly.
- 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.
- Polymarket runs deep liquidity on headline games and much thinner books on the rest of the slate, and its player-prop coverage is still filling in — check the size behind a quote, not just the quote.
- DraftKings
- The DraftKings sportsbook sets the line, prices both sides with its margin included, and takes the other side of your bet itself. DraftKings Predictions is a separate, CFTC-regulated product with its own pricing and its own state list.
- DraftKings' margin is inside the price. You pay it on every bet you place, whether that bet wins or loses.
- DraftKings offers the widest US player-prop menu of any venue on this site.
