Rockstar has not officially confirmed how many GB GTA 6 will be yet, so any exact number you see right now is speculation or based on early/placeholder data.

Quick Scoop

Most current info points to a very large install , likely well over 100 GB and possibly in the 150–250 GB range once all content and patches are included, but not the wild 750 GB rumors that were floating around.

What leaks and rumors say

  • Some early rumors claimed GTA 6 would be around 750 GB , but gaming outlets have called those numbers unfounded and unrealistic for a shipped game.
  • Other reports and commentary suggest early dev builds near 80 GB , with realistic final estimates typically landing around 200–250 GB once textures, audio, and updates are included.
  • Community discussions and fan predictions often cluster in the 150–200+ GB range, assuming a bigger map and higher-fidelity assets than GTA 5.

In forum-style discussions, players often say things like: “GTA 6 will probably be 150–200 GB at launch, then creep higher with online updates,” comparing it to modern Call of Duty and Red Dead Redemption 2 sizes.

Why it will be so big

  • Higher resolution textures, detailed open-world cities, and next‑gen lighting all push up file size, especially in a game on the scale of GTA 6.
  • Ongoing online updates and expansions are expected to add tens of GB over time, just like GTA Online and other live-service games.

What you should plan for (practically)

While nothing is final, a safe prep strategy for “how many GB will GTA 6 be” right now is:

  1. Expect at least 150 GB free for the base game, possibly more depending on platform.
  1. Leave extra headroom (another 50–100 GB) for day‑one patches, DLC, and online content over the first year.
  1. If you are on a console or a smaller SSD, consider clearing space or using a larger external/expansion drive in advance, since this will likely be one of the heaviest installs on your system.

Forum / trending context

  • The question “how many GB will GTA 6 be ” is trending in late 2024 and 2025 because pre‑release store pages sometimes show placeholder sizes (like odd numbers in MB) that are not the final install size, which has confused players.
  • Tech and gaming sites now routinely cover “GTA 6 file size speculation,” framing it as one of the biggest upcoming storage hogs of this console generation, but still within the range of other huge AAA titles rather than an impossible outlier.

Bottom line: Until Rockstar posts official system requirements, treat every exact GB number as an educated guess—but prepare for something in the 150–250 GB ballpark and growing with updates.
