There is no information available about an online mode in GTA 6. The developers have not made any official statements on this topic. Given that the release is already planned for next year, the details about the multiplayer component will likely be revealed later, or the feature may not make it into the final version of the game.
Speculations about an online mode in GTA 6 are not supported by any evidence. Arguments like "If the studio wants to make money, there must be an online mode" or "There was an online mode in GTA 5, so there will be one in GTA 6" are nothing more than unfounded assumptions.
It is too early to draw conclusions about the presence of an online mode in the new game, until Rockstar provides more information.
