It’s a footnote because SpaceX is going to be worth trillions. If Twitter were fully written down right after IPO SpaceX’s shares might not even have a bad day.
It may or may not be worth trillions. But the valuation right now based on the IPO sale price is .75 trillion. Which makes it vastly bigger than Twitter regardless.
It could nonetheless be worth trillions by the end of the day.
Space is the next great frontier and right now every single other company, and even country, remain orders of magnitude behind SpaceX. This could change in the future and viable competitors could emerge, public ownership could ruin SpaceX, or humanity's further entry into the cosmos could be delayed (Americans circa 1969 certainly probably also felt they were on the cusp of something great). But at current trajectories you're looking at something akin to there being one company that made ships better way better than everybody else, right before the Age of Sail kicked off.
Bro, they make 99% of the revenue providing internet connection where markets and governments have failed to provide good options. A trillion dollar valuation competing with the commodity cost of running fiber. Supporting off-grid internet is not a trillion dollar industry even combining it with all the revenue from other uses of satellites. It’s the next step in rockets which is more equivalent to better horse shoes than the age of sail.
I think most people, especially in this topic, know essentially nothing about SpaceX and are just going off political stuff. SpaceX have dropped the price to get stuff to space by about two orders of magnitude already, and there's no apparent reason Starship might not succeed in which case you're looking at even more orders of magnitude cost deduction.
Space is not, and cannot be, a frontier when it costs thousands of dollars to get a bottle of water into orbit. That suddenly changes when costs reach a sufficiently low threshold, and SpaceX is not only leading the race there but really the only significant player. Even China, with their vast resources, won't be able to compete unless they can reach near to technical parity with SpaceX. And, for now at least, they don't seem especially close and are, by far, the closest competitor SpaceX has, bro.
A similar path to Microsoft. Being the primary gate holder to a developing market segment aka space. In our modern overvalued stock indexes they are worth 750 billion before considering future growth.
The idea that companies can corner entire markets has been proven false time and time again. Every "tech" unicorn has their valuation propped up by the idea they'll be the "primary gate holder" to some billion or trillion dollar industry. For Uber it was Taxis, for Tesla basically all ground transport, etc. None of them have been borne out and competitors are already well established. Blue Origin is already nipping at their heels with the recovery of Never Tell Me the Odds last year.
UFO soft-disclosure is already underway (the Pentagon releases more and more evidence). The USA will go full disclosure before the end of Trump's second term. SpaceX will be granted monopoly on the reverse-engineered alien spacetime propulsion tech, becoming the most valuable company ever. The SpaceX IPO is the final act of the plan that was set in motion when president Eisenhower signed the pact with the Zeta Reticulans (aka "the greys") at Holloman Air Force Base in 1954.
To explore this (hopefully parody) alt history, I don't know why the us gov wouldn't waited 70 some years for spacex to reach this point to grant that monopoly versus handing it off to the usual collection of defense contractors, eg raytheon (or whatever they're called now), Rand, etc.
The Holloman Pact made the alien technology transfer contingent on launching an alien-human hybrid program. You see, the Zeta Reticulans mandate their technology to be stewarded by hybrids (similar to how China requires a 50% Chinese joint venture to gain access to their markets). The two species' geneticists started working together, and in 1971 the first viable hybrid was born: Elon Musk. Then we had to wait for the hybrid to mature, before it could be given stewardship of this sensitive technology. Meanwhile a generations-long cultural manipulation program was also underway, to prepare humanity for disclosure.
Of course it's sarcasm, but if it WAS true, it would be because the government was working in cahoots with all those defense contractors all along, until the Trump administration came along and decided to privatize it, at which point SpaceX seized its opportunity.
It could nonetheless be worth trillions by the end of the day.
