Converting 39¢ by hand
Treat the price as a probability: 39¢ is 39.00%. Decimal odds are one divided by that, 2.564, which bookmakers would display as 2.56. American odds follow from the decimal price: an underdog, so (2.564 − 1) × 100 gives +156. In fractional terms the closest traditional price is 61/39.
YES, NO and the spread
On a liquid market the YES and NO prices add up to about $1.00; at 39¢ the NO side should be near 61.00%. 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 2.533 decimal, at 5% 2.486. A sportsbook offering better than the effective price beats the market.
| Commission | Effective decimal | Effective American | Break-even |
|---|---|---|---|
| 2% | 2.533 | +153 | 39.48% |
| 5% | 2.486 | +149 | 40.23% |
