Wings Gaming wins 'Dota 2' TI6 and the biggest esports prize purse in history
On August 13, the Chinese Dota 2 team Wings Gaming defeated Digital Chaos 3-1 in the grand finals of The International 6, taking home a $9.1M prize – the largest sum ever awarded in esports. The total prize pool was over $20M.
Valve's International Championships achieve their sky-high prize totals via crowdfunding, with 25% of certain in-game item purchases added to the base prize pool. To add $19M, Dota 2 players spent around $77M on in-game items in the months leading up to TI6. Per #9 above, that's approximately 1.6 MLGs.
