Short answer: There have been multiple reports claiming Forza Horizon 6’s PC build leaked on Steam ahead of its official May 19, 2026 launch, with some sources noting unencrypted preload data and a large 155 GB file that appeared before release. However, official confirmation from Microsoft or Playground Games is still lacking, and the situation remains unverified beyond early reports and forum discussions.[1][2][5]
Details
- What happened: Reports allege that an unencrypted full build of Forza Horizon 6 was uploaded to Steam as part of a preload, bypassing the usual encryption that prevents pre-release playback. This led to widespread discussion on forums and social media as people claimed they could access or even run the game before its official launch.[5][1]
- Scope of leak: The leaked build is described in several outlets as roughly 155 GB, spanning the game’s assets and content. This size aligns with typical large modern PC game preloads, though exact file counts and encryption status are not independently verified.[4][1]
- Reactions and consequences: Coverage mentions widespread chatter, potential piracy activity linked to the leak, and at least one report of alleged enforcement or bans by publishers in some instances. Official statements from Microsoft or Playground Games have not been published as of the latest reports.[9][1]
- Reliability note: Given the nature of leaks, information should be treated cautiously until an official update is provided. Several outlets emphasize that the full picture remains unclear and that caution is advised when dealing with unofficial files.[2][1]
What to watch for
- Official confirmation or denial from Playground Games or Microsoft.
- Any statements about Steam preload encryption practices or post-launch patches addressing the leak.
- Updates on whether the leak affects launch timing, DRM, or early access windows for the Premium Edition.

Forza Horizon 6's complete 155GB build accidentally went live on Steam ten days early, letting players download and play the full Japan-set racer before its May 19th launch. One of gaming's biggest pre-release leaks ever.
tbreak.comSO what do we know LOL as I understand, it is it the Dev that uploads fils (encripted idealy ːsteamsaltyː ) and then Steam gets the decriptor to decript the files on release by pushing it to devices with preload? I dont think it will have more than 0.1-0.5% effect on sales since it is Online First game afterall but at this point I think they should just release this game earlier than planed for all of us that pre-ordered it ;) Take at least some ownership for your actions and do something...
