Remember, these megabillionaires are due to stock valuations, and live rich lifestyles on the basis of lending against the value of stock. If that value drops and a margin call forces actual selling, then Musk loses shares in Tesla.
I have to think this stunt is related to Musk needing some liquidity somehow, or being unable to cover private liquidity crunch with public assets.
TSLA is ludicrously overvalued. P/E is 150, based on Q4 earnings which were 1/3 "real" revenue, 1/3 mark-to-market-BTC (aka one shot), 1/3 CAFE/subsidies which Trump will nuke in 6 months.
But the "real" earnings that were already flat in Q4 are seeing a huge drop in EU/CN and who knows in the US. If "real" revenue drops 20%, the "real" earnings might drop 70% or more.
Anyway, that 150 p/e is ACTUALLY 450 in my mind, but after Q1 reports it will ACTUALLY be almost 1000 or worse.
The only thing keeping the stock afloat is AI hype, but 1000 p/e ratios are for people with market dominance and fundamental leads on competitors. Tesla is arguably middle of the road in both self driving and robots.
