Jury's still out on that. Elon Musk is still **trying** to get out of buying Twitter. Remains to be seen if he'll be successful because TWTR is fighting back.

I saw that shit last week after seeing him not tweeting for while then I went to check TWTR options and saw large volume in 37P, bought some and nothing happened that week

Bro he already sold TSLA shares to help finance the TWTR purchase and the stock suffered because of it. You’re saying a court is going to not want to enforce contractual obligations because Elon might sell more TSLA shares? TSLA shareholders know exactly what position they’re in by holding shares, and it’s not up to the courts to protect them from risk.

As a TWTR shareholder, I look forward to seeing Elon in Delaware court.

How do some of you do options without understanding how it works? Blows my mind. Anyway, TWTR closed at 36.86 today, so you're good. After hours doesn't apply to options until the following trading session. Edit: I'm wrong. Apparently, even though trading stops on Friday at 4, you could still be assigned in this case due to options pricing expiring on Saturday at noon.
