Understanding how Polymarket and prediction markets work
Polymarket is one of the top prediction market sites. If you’ve come across our Polymarket review, you’ll know the site offers contracts on a range of categories, from culture and sport to cryptocurrencies and politics.
The most popular markets offered on the site are binary or yes/no contracts. Here, the market asks a question, like Canada to win against Morocco on July 4th – yes or no? The market is priced according to the probability of the outcome. For instance, if the likely outcome is “yes”, it will be priced at $0.85 (85% probability), and “no” at $0.15.
If you choose “yes” and your prediction is correct, you’ll receive $1 for every share you purchased at $0.85 ($0.15 profit). If you’re incorrect, you’ll receive $0.00.
