How could Musk possibly have done this, which must have been against the advice of his Bankers?
"I'm sending men to mars, ergo, I know more about M&A than i-bankers?
This is the kind of hubris that takes people down.
That's presumably what he told people and not "hey I'm just joking around, make sure to write the terms so the deal never actually completes"
And it's doubtful Musk was so dumb he'd enter into this contract 'just for fun' knowing the terms.
I suggested he did want to buy it, got bad advice or didn't listen to his bankers, and then the market crashed, and now he's in a bind.
