That tweet was likely intentional foreshadowing of the coming split. He posted it at 8:11 and they announced the split on 8/11.

I have no basis for this suggestion, but I’ve actually been thinking lately that SoftBank and Musk coordinated the TSLA infinity squeeze that we’ve all been watching.

It’s a great way to make a massive investment in TSLA, at the price you were willing to pay anyway, while sending the stock through the roof so the company can take the needed liquidity from the market.

TSLA added one of SoftBank’s largest financiers to the board in late April.
