Independent profile PlayStation Game Size, which tracks PlayStation game records and updates, claims to have found references to multiplayer features in technical data for Grand Theft Auto VI, or GTA VI, on the platform's systems. The records have fueled speculation about a possible successor to GTA Online, the online mode for Grand Theft Auto V, but they do not represent an announcement from Rockstar Games.

The profile shared three identifiers, or technical names, associated with the game: joinSession, launchActivity, and launchMultiplayerActivity. The names suggest, respectively, actions to join a game session, start an activity, and start an activity with more than one player. Their specific functions in these records have not been officially confirmed.

The presence of these entries does not demonstrate that a multiplayer mode is complete or playable. It also does not establish when a potential online feature would be available.

On the official GTA VI page, PlayStation describes the game as a single-player experience. Rockstar also used that description in its preorder announcement, which mentioned the existing GTA Online without announcing a multiplayer component for the new game.

Grand Theft Auto VI is Rockstar Games' next game and is set in Leonida, a fictional state inspired by Florida. It is scheduled to launch on November 19, 2026, for PlayStation 5 and Xbox Series X|S.
