| 1,000 | 587.30 | 1,587.30 |
Break-even and long-run results
Because the price is a probability, the break-even rate is the price itself: 63.00%. If your own estimate of the outcome is higher than 63.00%, the share is value; if it is lower, it is not.
| Win rate | Return on stake |
|---|---|
| 50% | -20.6% |
| 55% | -12.7% |
| 60% | -4.8% |
| 63% | -0.0% |
| 65% | 3.2% |
63¢ is a favourite's price on a prediction market, implying 63.00%. Compare it with a sportsbook's price on the same event: if the book offers better than -170 on the same side, or better than the complement on the other side, one of the two venues is mispriced.
Converting 63¢ by hand
Treat the price as a probability: 63¢ is 63.00%. Decimal odds are one divided by that, 1.587, which bookmakers would display as 1.59. American odds follow from the decimal price: a favourite, so −100 divided by (1.587 − 1) gives -170. In fractional terms the closest traditional price is 37/63.
YES, NO and the spread
On a liquid market the YES and NO prices add up to about $1.00; at 63¢ the NO side should be near 37.00%. 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 1.576 decimal, at 5% 1.558. A sportsbook offering better than the effective price beats the market.
| Commission | Effective decimal | Effective American | Break-even |
|---|---|---|---|
| 2% | 1.576 | -174 | 63.47% |
| 5% | 1.558 | -179 | 64.19% |
