You can play GTA 6 on PlayStation 5 and Xbox Series X/S at launch. A PC version is not confirmed for launch day based on the sources I found, and PS4/Xbox One are not listed as supported.

Platform scoop

  • Confirmed for launch: PS5, Xbox Series X, Xbox Series S.
  • Not confirmed yet: PC.
  • Not supported at launch: PS4, Xbox One.

Quick note

Some recent videos and forum posts repeat the same idea, but the clearest source I found says the launch platforms are the current-gen consoles only. The PC release, if it happens later, is still being treated as a separate future version rather than a launch version.

TL;DR: If you want GTA 6 at launch, plan on a PS5 or Xbox Series X/S.
