Cost
Across 497 two-sided player-prop markets Polymarket currently prices, the two sides add up to about 6.71% above a fair 100% — that gap is Polymarket's hold. One-sided markets are excluded from this figure because there is no second price to add against the first.
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.

What Polymarket is
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 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.
Polymarket's edges tend to be largest on games the order book is actively trading and unreliable on markets where almost nobody is quoting.
