What are the most profitable activities in GTA Online?

The most profitable activities in GTA Online are a combination of heists, businesses, and special events. The Cayo Perico Heist stands out as an extremely lucrative venture, allowing solo players to make significant profits by infiltrating a private island and stealing valuable contraband. Similarly, the Diamond Casino Heist offers substantial payouts for a well-executed robbery. Outside of heists, running businesses such as the nightclub, bunker, or cocaine lockup can generate continuous income; these become more efficient when paired with VIP or CEO work and missions from the Terrorbyte. Players should also take advantage of weekly updates that often feature double money and experience for select missions and races, maximizing earnings simply by participating in those activities during their bonus periods. Engaging in these ventures strategically is key to maximizing wealth in the dynamic economy of GTA Online.
