The evidence against this is that tsla stock has gone up since musk said the deal was "on hold". This may be because the market expects him to not have to increase supply by selling more shares, but he's already trying to arrange outside funding to limit what he has to sell.

It could be that confidence in musk and his brand is having more of an impact on share price than supply and demand. He's behaving erratically and is clearly distracted from running tesla by this twitter fiasco. I'm not sure what weighs more on the minds of institutional investors.
