The most profitable heist in GTA 6. Requires a 4-player crew and prep missions. Diamond approach recommended for max payout.
The GTA 6 Diamond Casino Heist payout money method centers on breaching the casino vault using either a stealth or loud approach, with the Diamond Approach targeting jewelry and cash directly for the highest guaranteed payout per run. Unlike passive businesses, this method requires active setup work but delivers one of the largest single-session paydays in the game.
To maximize payout, complete all available prep missions beforehand, since skipping them significantly reduces your final take and increases the difficulty of the vault sequence itself. Running the heist with a full four-player crew and splitting roles by strength, gunman, hacker and driver, produces the most consistent results and keeps the vault timer comfortable.
With full prep completed and the Diamond Approach selected, expect a net payout in the $2.2 million to $2.4 million range per run. The heist has a real-time cooldown before it can be repeated, making it best suited for scheduled high-value sessions rather than constant repetition like smaller money methods.
