Before we get started, itโs important to note that Polymarket odds donโt exist in the conventional sense. Instead Polymarketโs prediction markets display prices that represent real-time probabilities shown as percentages.
Top Polymarket Alternative for October
Weโve put together this guide to explain why you should look for prices rather than odds, and how you can buy shares based on those prices. You can even sell them before the event ends. Weโll also provide a quick comparison with regular betting to help you see the differences between betting odds and prediction market probabilities.
If youโre interested in
Polymarket sports markets
or any other prediction market on offer, you need to know how it works. Prediction markets are based on shares, also known as contracts. Youโll always have two contracts indicating the yes or no outcomes that could occur. You then need to consider whether you believe the event will happen or not, and decide whether to purchase contracts accordingly.
Focusing on Yes or No Probabilities
Letโs look at a sporting example to illustrate how this works. The LA Clippers are going to play the Phoenix Suns. You will see two shares indicating the current probability of each team winning. For example, the LA Clippers may have a share price of $0.35 while the Phoenix Suns have a share price of $0.65. This means the market believes there is a 35% chance of the LA Clippers winning the match. Conversely, there is a 65% chance of the Phoenix Suns winning the match. These figures show the Polymarket odds of each event occurring, as determined and believed to be true by those buying shares.
If you believe the LA Clippers are going to win, you must decide how many shares to purchase at $0.35 each. If they lose, you will lose those funds. If they win, you will receive $1 per contract. So, if you bought 100 shares for a total of $35, you would receive 100 shares paid at a total of $100, or $1 each. This would be a profit of $65.

You Can Buy Shares in Prediction Markets and Sell Them Too
As more people buy shares on
prediction markets
– based on either yes or no predictions – the prices for those options may change. This occurs with regular betting as well. However, you will notice one key difference – you can decide to sell your shares whenever you wish. You may decide that you can achieve a better outcome by doing this, rather than waiting until the event ends, when you may be on the wrong side of the result.
