Didn’t Zuckerberg just lose $60 or $70 billion in one day when Meta crashed after his virtual reality stuff turned out to be a dud? I’m pretty sure Bezos has lost that much as well.
Musk doesn’t need to make money from Twitter. He can run it as a vanity project, or as his contribution to free speech, or whatever. He could lose every nickel and still be the richest man in the world. To,be sure, he’d like to make enough money that he doesn’t have to pay investors back out of pocket, but he doesn’t have to.
And when Starlink goes public, Musk will probably at least double or triple his wealth. Don’t forget that SpaceX is a private company, and it absolutely dominates space launch.
Let’s talk about Starlink for a minute. Before Musk came along, the idea of putting 30,000 - 50,000 satellites in LEO for cell service was a fantasy. But Musk lowered the cost of space launch to the point where it became a reality, then gambled billions of dollars on making it work. He also realized the synergy of using Starlink to increase the cadence of Falcon 9 launches, lowering per-launch costs further. No one else had the vision or the balls to take such big swings.
And Starlink may be the biggest advance in standards of living for the third world any individual has ever managed. It has the possibility of providing open communicatiins in countries where the government tries to control information, and of course it is a big factor in the war in Ukraine.
When he takes Starlink public, Musk could easily earn another $100 billion. SpaceX itself has been valued at $74 billion, but if Starship works properly expect that to double as well over the next few years. As it is, SpaceX launches more than double the mass to orbit than all other companies and governments in the world combined.
Far from going broke, Musk is actually the #1 candidate for being the first trillionaire. Twitter is not that important to this. If he lost half of his investment and sold it, the loss would be in the range of a number of losses he’s suffered when the market took a dive. He’s used to it. If Starship blows up on the pad, it will cost him billions. Musk takes big swings. He’s diversified enough that no one failure or even several can take him out of the game.
