How it works

Three steps, no jargon

Full explainer

Pick a side

Every market is a yes-or-no question with a deadline and a written resolution source. Buy YES or NO at the current price.

Prices are probabilities

A share costs between 1¢ and 99¢. The price is the market's estimate of the odds. Buy low, and you profit more when you are right.

Winners settle at $1.00

When the question resolves, every winning share pays exactly one dollar. Losing shares pay nothing. Sell early any time before close.
