Gold: $114.4 billion
Silver: $158.2 billion
Turkish Lira: $17.7 billion
SpaceX investment: $675 to $728 billion
The Turkish Lira one is brutal. $44 billion in one of the world's worst performing currencies over the same period would have lost over 60% of its value.
But the SpaceX number is the one that stops you cold. If he had simply taken that same $44 billion and put it into the company he was already building, it would be worth somewhere between $675 and $728 billion today based on SpaceX's current valuation.
He spent $44 billion to own Twitter. The opportunity cost was potentially $700 billion.
Whether X becomes something that justifies that trade is still an open question. But the math on what he gave up to own it is extraordinary.
