Does gta online share progress with gta v story mode?

The only verified source available is a description of Grand Theft Auto V, which outlines its single‑player narrative and gameplay mechanics. This source does not mention any interaction between the single‑player story mode and the multiplayer component, Grand Theft Auto Online. Consequently, there is no documented evidence that achievements, character progression, or other in‑game data are synchronized between the two modes. Without additional reliable references, we cannot confirm a share of progress between GTA V and GTA Online.
