How to Earn Shark Cards in GTA Online for Free in 2025

Shark Cards give you money to spend in GTA Online, from $250,000 to $10m, and can be bought directly from Rockstar, starting at $5 (or from a 3rd-party seller for only $3). But who wants to spend their own money?

I get Shark Cards for free by doing paid market research tasks online, then using the money to buy them from a 3rd-party seller. I'll explain this method, which usually earns me around $4m to spend in GTA Online, and then go over discounts you should take advantage of. 

Using Freecash to get free Shark Cards 

The best way to earn Shark Cards is by using Freecash to get the funds, and then buying them from a third-party seller. Freecash is a website where you can earn money by completing market research tasks, like answering surveys or levelling up in a new game as a player tester. 

With this method, I can reliably buy a Whale Shark Cash Card every week for just a few hours of answering surveys and gaming. But you could earn more; the average daily user on Freecash makes $35, while top earners race to make $5000 every month! 

They have an excellent Trustpilot score of 4.7 and a 24/7 support team, so you can feel confident about getting paid quickly and correctly. 

Using Buff to get free Shark Cards 

Buff is basically a loyalty scheme for gamers; keep it running in the background while you game, and earn a very small amount for the time you spend playing games.

If you play GTA V with Buff running in the background, you will slowly earn points that can be redeemed for Steam/PSN/Xbox Live gift cards, which can then be used to buy Shark Cards. 

Buff is an incredibly slow way to get Shark Cards compared to Freecash, but it is free, easy to set up, and requires no ongoing effort. 

Discounts on Shark Cards 

Although there are very few ways to get Shark Cards for free, there are multiple ways to get a discount.
