Top 5 by number of deposits
Transaction volume tells a different story from raw deposit value. Stake again leads comfortably with 2.48 million individual deposits in May, followed by Rainbet at 876,000 and Roobet at 679,000. Shuffle recorded 544,000 transactions, while 1win rounded out the top five with 357,000 deposits — a notable new entry into the top five by transaction count.
Top 5 by average deposit size
The average deposit metric highlights the higher-spending end of the market. Sportsbet.io leads with an average deposit of $2,700, followed by Cloudbet at $2,490 and Gamba at $2,400. BC Game sits fourth at $1,590 per deposit, with Winna rounding out the top five at $1,500.
Reading the May data
May’s figures reinforce several established patterns while also introducing some notable developments. Stake’s structural dominance remains unchallenged — its $1.72 billion dwarfs the combined totals of platforms ranked two through five. The ranking has also expanded significantly this month, with 37 platforms tracked compared to previous months, giving a broader and more detailed view of the mid-tier and emerging operator landscape.
The most striking new entry is 1win at ninth place with $76.4 million in deposits and 357,000 transactions — a platform previously absent from the top rankings that has clearly made meaningful inroads into the crypto casino space. Spartans is another new name in the rankings at 13th with $36.6 million, as is Gamba at 25th — notable for its $2,400 average deposit, placing it third in the high-roller metric despite its modest overall volume.
The fundamental split in the crypto casino market remains clearly visible: mass-market platforms like Stake, Rainbet and Roobet dominating by volume and transaction count, while premium-positioning platforms like Sportsbet.io and Cloudbet serve a smaller but significantly higher-spending player base.
