The fifth annual Dota 2 main tournament “The International 2015 (TI5)” has already outperformed last year's record prize pool of 10.9 million US-Dollars two months before the start of the tournament and is currently (06/05/2015) at $ 11,388,719.
In the first two years (2011/2012) the prize money was at 1.6 million US-Dollars – sponsored by Valve. With the third International 2013 Valve gave the Data 2 community the option to rise the total prize pool by buying a Compendium – an electronic manual with information about players, teams and many in-game extras – of which 25% of the purchase price is added to the total prize pool. Thanks to the Dota 2 community the TI3 already reached a prize pool of nearly 2,874,381 $ and took the title of the most highly endowed eSports tournament.
With The International 4 (2014) the toal price money reached the incredible amount of nearly 10.9 million US-Dollar.
The upcoming The International 2015 already outperformed last year's prize pool record 58 days before the tournament and continues rising.
