I believe the tournament will be played 100% in the US, so NYCFC will host Atlas and Red Bulls will host NYCFC. The game NYCFC will host will be at either YS or Citi field as that is the 18th home game STH paid for (probably).
Every team will play two matches in the Group Stage, with the top two teams from each group, as determined by points, advancing to the Knockout Stage Round of 32. No matches in the Leagues Cup Group Stage will end in a tie. If a game is tied after 90 minutes, the game will proceed to a penalty shootout. For tiebreakers and other competition items, the Leagues Cup 2023 Competition Guidelines will be published in the coming months
The 15 groups are now set for the inaugural edition of the highly-anticipated Leagues Cup 2023, the official Concacaf competition where all 47 clubs - 18 from LIGA MX and 29 from MLS - will play in a World Cup-style tournament that will qualify three clubs for the 2024 Concacaf
