Hearthstone could afford to fund Dota 2’s The International prize pool every month

According to findings released by SuperData Research, Blizzard’s Hearthstone is bringing in $20 million a month. That’s a lot of virtual cards. The estimate is based on surveying gamers and tracking over 250 million digital collectible card game transactions between October 2011 to June 2015. Analysts at SuperData concluded that 37 million gamers worldwide play digital CCGs with Hearthstone leading the field at 17 million active players thanks to its strong ties to other Blizzard games.

“Being able to build on a vast, pre-existing narrative economy allows both existing and new players to quickly find a touchpoint with the game, thereby establishing a different relationship compared to the majority of free-to-play titles currently available on iOS and PC.”

SuperData noted that while Hearthstone makes about $2 million per month more than Valve’s Dota 2, it is absolutely crushed by League of Legends’ $123 million a month revenue. Hearthstone’s The Grand Tournament expansion will be the latest card pack in the series.
