How to Make Mets vs Pirates Predictions at Kalshi

If you are new to the concept of trading at Kalshi, here’s an example of how you could use your bonus on this week’s Mets vs Pirates matchup:

  1. Kalshi’s Mets vs Pirates markets cover the overall game outcome, plus in-game events such as strikeouts, home runs and hits. To make a prediction, you need to trade contracts in potential outcomes.
  2. Each outcome has a contract price of between $0.01 and $0.99. For example, if the Mets are priced at $0.30 to beat the Pirates and you want to buy 50 contracts on that outcome, it will cost you $15 (50 x $0.30).
  3. Once an event finishes, successful contracts settle at $1, whilst unsuccessful contracts settle at $0.
  4. If the Mets beat the Pirates, your payout would be $50 ($1 for each of your 50 contracts). This would give you a net profit of $35 (the $50 payout minus the $15 cost of the contracts).
