What are the best businesses to own in GTA Online?

The best businesses to own in GTA Online for maximizing profits are the Nightclub, Vehicle Cargo Warehouse, and Special Cargo Warehouse. The Nightclub works well because it accumulates goods passively over time without the need for re-supplying, making it a great source of steady income with minimal effort. The Vehicle Cargo Warehouse from the Import/Export update is lucrative as well; sourcing high-end vehicles and selling them can yield significant profit margins. Additionally, the Special Cargo Warehouse from the CEO activities can be highly rewarding, especially when selling large stockpiles of goods during high-demand periods. Other notable mentions include the Bunker for arms trading and the MC Businesses—particularly Cocaine Lockup—although they require more active management and can attract attention from other players, potentially increasing risk. Combining these businesses strategically can create a robust income stream and make one a tycoon in the game's ever-evolving economy.
