Gut says they can sustain a ~$1T market cap off current growth of Starlink and Starlink mobile services and Falcon as the launch vehicle, but for a $2T valuation they have to solve Starship reusability and prove orbital data centers are cost competitive or minimally cost + cost of time competitive with terrestrial data centers. Just a guess, but think they maintain a $2T valuation for ~1 year and then fall into the $1-1.5T valuation if they have yet to re-fly a Starship. Small amount of float on their stock and boosts from index buying will have it elevated for ~6 months to a year. Just a guess.
Between lowering launch costs and Starlink, SpaceX is the "commercialization of space" that has been talked about for decades. That part of the business will obviously thrive.
However when it comes to moon rockets or later going to Mars, I don't really see the commercialization. It's just how much is the government willing to spend on it. Any potential commercialization is a long, long way off. Maybe your grandkids will make a killing on the stock you buy next month.
