Yeah, it's certainly possible he's on the spectrum.
On the other hand, he reminds me of some of the trust-fund kids I knew back when I hung out in the local art/music scenes. At times, it seems like he's trying really hard to be edgy. And the buying into existing companies while demanding to be named as a "founder" or acting like he invented it all is definitely the sort of behavior I saw out of the trust funders.
Then there's the fact that he's a billionaire. You look at behavior of people that rich and you see a lot of people acting like complete assholes. No one can stay in their inner circles and say no, they're bribing politicians to get their way on everything, etc.
