Rockstar and the PlayStation Store have not listed a download size for Grand Theft Auto VI on PS5. The 150 GB figure floating around is a community estimate based on the scale shown in the trailers and the size of recent AAA releases, not an official number. Treat it as a guess, not a fact.
The game launches November 19, 2026, digitally only on PS5 and Xbox Series X|S. No physical disc. That means the full install will hit your SSD on day one, and with no disc, you’ll need the storage space free before preloading starts. Rockstar hasn’t said when preloading begins either, though it typically opens a few days before launch.
If you’re planning ahead, the PS5’s internal SSD is 825 GB on the base model, of which roughly 667 GB is usable. A 150 GB install would leave plenty of room, but if the final size lands higher, you may want an external NVMe SSD. Keep an eye on the official Newswire post closer to launch; that’s where Rockstar will confirm the exact figure.
