Forza Horizon 6 has leaked a week ahead of launch.

 Forza Horizon 6 leaked online roughly a week before its official launch after an unencrypted PC build was accidentally uploaded to Steam servers. The leaked files reportedly spread quickly across piracy sites before Microsoft removed access. 

According to reports, the leaked build is around 150–155GB and includes the full game. Playground Games confirmed it was aware of the situation and warned that anyone accessing the leaked version could face franchise-wide and hardware bans. 

The game itself is set in Japan and is expected to launch officially on May 19, 2026, with Premium Edition owners getting earlier access on May 15. It’s planned for Xbox Series X/S, PC, and later PS5. 

A lot of fans online are comparing this to other major game leaks in recent years, especially because the full playable build reportedly escaped before launch instead of just screenshots or spoilers.
