The price is currently $46 and considering the stock market is down as a whole, the $54 price will easily be eclipsed in the near future imo. Granted Musk will sell his stock and that price will go down, but I would balk at this offer if I had any skin in the game.
If you're basing this on the stock market as a whole being down, surely you'd make more money by selling to Elon at $54 while it's still down, and re-investing your money in other stocks - letting you get the upside twice, once from Elon and once from the stock market going up.
