Early this morning, the prize fund for the Dota 2 International tournament crossed the $10 million mark. Remarkably, just $1.6 million of the prize fund was provided by Valve; the rest was contributed by members of the Dota 2 community who are eager to get their hands on some in-game items, and to support their favorite teams and the nascent esport as a whole. With a prize fund of over $10 million, The International 4 is now larger than The Masters golf tournament.
