MLB players's salaries don't cover postseason play, so a unique system exists to financially compensate them. Major League Baseball derives these bonuses — which are officially known as postseason shares — from a players' pool. Per MLB.com, the funding is pulled from: "50% of the gate receipts from the Wild Card Games; 60% of the gate receipts from the first three games of the Division Series; 60% of the gate receipts from the first four games of the League Championship Series; and 60% of the gate receipts from the first four games of the World Series."
The winning team, as well as the other 11 that made it into postseason play, then determine how the money they receive will be split among the players and staff, with the amount changing based on how many full and partial shares the team allocates. For instance, in 2022, the Astros dolled out 59 full shares, while the Phillies, which lost the World Series, gave out 72, per MLB.com.
