Is GTA 6 coming to Nintendo Switch?
The direct answer
Not announced, and unlikely at launch. GTA 6 is confirmed only for PS5 and Xbox Series X|S.
Rockstar has said nothing about a Nintendo Switch or Switch 2 version. The original Switch can’t realistically run a current-gen-only GTA 6, though the more powerful Switch 2 makes a future port slightly less far-fetched.
For now, treat any "GTA 6 on Switch" claim as speculation — there is no announcement, and Rockstar has not brought a current-gen tentpole to Switch hardware.
