Re: What's the endgame?
If the deal falls apart, say, due to his now-complex network of co-financiers getting cold feet, then the deal will collapse. It's not guaranteed that it goes through. In this scenario he is due to pay Twitter $1Bn in cash, but that is far less of a penalty than whatever he's looking at from in the collapse of stocks, or even from the loss of value in Tesla because of the way he's using those shares to underwrite his Twitter buyout.
