I feel like with the Khans being so rich and AEW making some money back through ticket sales, PPV buys and merch, Tony Khan could keep it going indefinitely as long as it's not losing a ridiculous amount of money. He could probably scale it down to a 90s ECW or current year ROH or TNA size production, make half what he puts into back through ads, tickets, merch and PPVs and keep going for the rest of his life without running out of money. If Tony's dad dies and leaves him one quarter of his fortune, Tony can spend $100-million a year and not run out of money until he's 80, and that's assuming none of it is invested in the market or accumulating interest. AEW is going to go for as long as Tony wants it to.
