Question 1

How do Polymarket cents convert to probability?

Accepted Answer

Directly: a share priced at 65¢ implies a 65% probability of that outcome. Price and implied probability are the same number in prediction markets — every cent is a percent.

Question 2

How do I convert cents to decimal odds?

Accepted Answer

Decimal odds = 100 / price-in-cents. A 40¢ share equals decimal odds of 2.50: stake $1, receive $2.50 total if you win.

Question 3

How do American odds relate to cents?

Accepted Answer

For favorites (price > 50¢): American = −100 × price / (100 − price). For underdogs (price < 50¢): American = +100 × (100 − price) / price. A 65¢ share is about −186; a 20¢ share is +400.
