Can you explain why? Maybe I'm missing a lot here, but what is spacex going to do to justify a valuation of, say, $200m over the next 20 years? If starlink succeeds it might be able to capture probably no more than 5% of the Isp market, which will probably correspond to around $50bn of revenue in a year in a couple of years. The satellite launch market is currently around $5bn a year, I think, or spacex currently has revenues of that amount and I've heard Musk say that he expects that part of their revenue to roughly top out at that amount. Even if that industry, say, doubles in the next 20 years, that's not that much revenue to warrant a >$200bn valuation. Most of the other potential revenue sources are all in theory highly lucrative, but I would seriously doubt that spacex would see any significant revenue from a colony on the Moon or on Mars in our lifetime, though I might just lack the imagination. Can you explain why you would want to own this company?
