61¢ is a favourite's price on a prediction market, implying 61.00%. Compare it with a sportsbook's price on the same event: if the book offers better than -156 on the same side, or better than the complement on the other side, one of the two venues is mispriced.

Converting 61¢ by hand

Treat the price as a probability: 61¢ is 61.00%. Decimal odds are one divided by that, 1.639, which bookmakers would display as 1.64. American odds follow from the decimal price: a favourite, so −100 divided by (1.639 − 1) gives -156. In fractional terms the closest traditional price is 39/61.

YES, NO and the spread

On a liquid market the YES and NO prices add up to about $1.00; at 61¢ the NO side should be near 39.00%. Anything above $1.00 in total is the spread, the prediction-market equivalent of a bookmaker's vig. Enter both sides in the Polymarket converter to measure it.

Fees and comparison with sportsbooks

Fees, where a market charges them, come off profit and work exactly like exchange commission. At 2% the share is worth 1.627 decimal, at 5% 1.607. A sportsbook offering better than the effective price beats the market.
