Well, the XMG 2.0 prize pool is currently around $265k. From a base of $50k then the additional $215k is from ticket sales. With tickets at $8 and 25% going to the prize pool, that about $860K in sales. If Valve takes 30%, then $860K - 30% - (860k x 25%) leaves $387k in profit. If that $50K base had to be fronted (probably not, since sponsors), then $337K. Some of that needs to pay for (the creation of) compendium perks. Some may go to LAN finals for team travel/hotels (if they are having them). But it's entirely possible that over $300k goes to the XMG guys as profit.
