100.000 decimal, +9,900 American, 1.00% implied probability
Buying at 1¢ means risking 1¢ to win the rest of a dollar. That is a payout ratio of 100.00 (decimal odds) or +9,900 in American notation, and it implies an implied probability of 1.00% probability before fees.
What a 1¢ 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 10,000.00, a profit of 9,900.00.
| Stake | Profit | Total return |
|---|---|---|
| 10 | 990.00 | 1,000.00 |
| 25 | 2,475.00 | 2,500.00 |
| 50 | 4,950.00 | 5,000.00 |
| 100 | 9,900.00 | 10,000.00 |
| 500 | 49,500.00 | 50,000.00 |
| 1,000 | 99,000.00 | 100,000.00 |
Break-even and long-run results
Because the price is a probability, the break-even rate is the price itself: 1.00%. If your own estimate of the outcome is higher than 1.00%, the share is value; if it is lower, it is not.
| Win rate | Return on stake |
|---|---|
| 1% | 0.0% |
| 50% | 4,900.0% |
| 55% | 5,400.0% |
| 60% | 5,900.0% |
| 65% | 6,400.0% |
A 1¢ share is a longshot: 1.00% by the market's estimate, paying 9,900.00 per 100. Thin order books at low prices mean the quoted price and the price you actually get can differ by several cents.
Converting 1¢ by hand
Treat the price as a probability: 1¢ is 1.00%. Decimal odds are one divided by that, 100.000, which bookmakers would display as 100.00. American odds follow from the decimal price: an underdog, so (100.000 − 1) × 100 gives +9,900. In fractional terms the closest traditional price is 99/1.
YES, NO and the spread
On a liquid market the YES and NO prices add up to about $1.00; at 1¢ the NO side should be near 99.00%. 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 98.020 decimal, at 5% 95.050. A sportsbook offering better than the effective price beats the market.
| Commission | Effective decimal | Effective American | Break-even |
|---|---|---|---|
| 2% | 98.020 | +9,702 | 1.02% |
| 5% | 95.050 | +9,405 | 1.05% |
