How to make your predictions at Polymarket

As we outlined in our ‘Is Polymarket legal in New York?’ article, before you start making predictions at Polymarket, it is essential to have a completely clear understanding of how the markets work and how to make your predictions. After all, whilst playing prediction markets is a lot of fun, it does come with a financial risk. With that in mind, here are the key facts you need to know:

  • To make a prediction at Polymarket, you need to buy or sell contracts for potential outcomes on upcoming events.
  • These outcomes will be based on binary, scalar or multiple choice questions.
  •  A binary question has a yes/no answer, a multiple choice question has several possible outcomes, whilst a scalar question market comes with a set of potential range-based outcomes.
  • Each potential outcome has a price of between $0.01 and $0.99.
  • The higher the price, the greater the chance of the outcome occurring. For example, a price of $0.85 indicates there is an 85% chance of the outcome happening, but a price of $0.20 means that an outcome has just a 20% chance of happening.
  • Prices are dictated by trader activity. If more people buy contracts on a certain outcome, the price attached to it will go up.
  • As soon as an event is over, all successful outcomes settle at a price of $1.00, whilst unsuccessful outcomes settle at $0.
  • Your contracts on successful outcomes, payout based on the difference between $1 and your contract purchase price.
  • For example, if you purchase 100 contracts at $0.40, it will cost you $40 (100 x 0.40). If the contract settles as a winning one, you will receive a payout of $100 (100 x $1), and your overall profit will be $60 ($100 – $40).
  • However, when you buy contracts on outcomes that are unsuccessful, you lose the value of those contracts.
