Is there any shared progress between gta v modes?

The Wikipedia excerpt describes Grand Theft Auto V as an open‑world action‑adventure game with a single‑player story featuring three protagonists and mentions the game world and setting. It does not discuss the relationship between the single‑player campaign and other modes such as GTA Online, nor does it state whether any progress, items, or achievements carry over between them. Therefore, based on the verified evidence, no conclusion can be drawn about shared progress across modes.
