1.333 decimal, -300 American, 75.00% implied probability
Buying at 75¢ means risking 75¢ to win the rest of a dollar. That is a payout ratio of 1.33 (decimal odds) or -300 in American notation, and it implies an implied probability of 75.00% probability before fees.
What a 75¢ share pays
Each share pays $1.00 on a win, so the profit per share is a dollar minus the price. On 100 dollars' worth of shares the return is 133.33, a profit of 33.33.
| Stake | Profit | Total return |
|---|---|---|
| 10 | 3.33 | 13.33 |
| 25 | 8.33 | 33.33 |
| 50 | 16.67 | 66.67 |
| 100 | 33.33 | 133.33 |
| 500 | 166.67 | 666.67 |
| 1,000 | 333.33 | 1,333.33 |
Break-even and long-run results
Because the price is a probability, the break-even rate is the price itself: 75.00%. If your own estimate of the outcome is higher than 75.00%, the share is value; if it is lower, it is not.
| Win rate | Return on stake |
|---|---|
| 50% | -33.3% |
| 55% | -26.7% |
| 60% | -20.0% |
| 65% | -13.3% |
| 75% | -0.0% |
75¢ is a favourite's price on a prediction market, implying 75.00%. Compare it with a sportsbook's price on the same event: if the book offers better than -300 on the same side, or better than the complement on the other side, one of the two venues is mispriced.
Converting 75¢ by hand
Treat the price as a probability: 75¢ is 75.00%. Decimal odds are one divided by that, 1.333, which bookmakers would display as 1.33. American odds follow from the decimal price: a favourite, so −100 divided by (1.333 − 1) gives -300. In fractional terms the closest traditional price is 1/3.
YES, NO and the spread
On a liquid market the YES and NO prices add up to about $1.00; at 75¢ the NO side should be near 25.00%. 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 1.327 decimal, at 5% 1.317. A sportsbook offering better than the effective price beats the market.
| Commission | Effective decimal | Effective American | Break-even |
|---|---|---|---|
| 2% | 1.327 | -306 | 75.38% |
| 5% | 1.317 | -316 | 75.95% |
