Because the price is a probability, the break-even rate is the price itself: 11.00%. If your own estimate of the outcome is higher than 11.00%, the share is value; if it is lower, it is not.
| Win rate | Return on stake |
|---|---|
| 11% | 0.0% |
| 50% | 354.5% |
| 55% | 400.0% |
| 60% | 445.5% |
| 65% | 490.9% |
An 11¢ share is a longshot: 11.00% by the market's estimate, paying 809.09 per 100. Thin order books at low prices mean the quoted price and the price you actually get can differ by several cents.
Converting 11¢ by hand
Treat the price as a probability: 11¢ is 11.00%. Decimal odds are one divided by that, 9.091, which bookmakers would display as 9.09. American odds follow from the decimal price: an underdog, so (9.091 − 1) × 100 gives +809. In fractional terms the closest traditional price is 89/11.
YES, NO and the spread
On a liquid market the YES and NO prices add up to about $1.00; at 11¢ the NO side should be near 89.00%. 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 8.929 decimal, at 5% 8.686. A sportsbook offering better than the effective price beats the market.

|---|---|---|---|
| 2% | 8.929 | +793 | 11.20% |
| 5% | 8.686 | +769 | 11.51% |
