About #1, the first result in my search says:

> the global data center market size was estimated at USD 383.82 billion in 2025

Getting that entire market, with Apple-like profitability would leave SpaceX as an overvalued stock that only makes sense if there are possibilities for growth.

On #2, replacing every single white-collar job on the world and capturing 100% of their salary would leave SpaceX with a P/E close to 2.

On #3, Visa seems to have earnings of about 10% of all datacenters up there. So, no, that's not enough even for a high-growth business.

On #4, IATA says the air-travel market is about $800B large. So, if SpaceX gets all of it, it would still have a P/E larger than 2.

So yeah, either they create an all-capable AGI or they create some rocket that is cheaper to run than an airplane... And they better be the only ones on that market, and capture most of the value they create.

"Extremely unlikely" is a huge understatement.
