Those who will invest on SpaceX IPO, will you buy Day 1? or wait? Why?

I’ve been following the SpaceX IPO for over 10 years and plan to put a significant amount in and hold for 10–15 years.

That said the current implied valuation already looks very high, and I amm struggling to reconcile it with realistic forward returns. I’m confident in the long-term story, but I’m questioning whether the risk-adjusted upside still justifies the entry price, or if returns are more likely to be solid but not extraordinary (e.g., lower IRR than a typical “home run” outcome).

Curious how you’d think about underwriting it at IPO day market cap. Should we jump on from Day 1 or see 1M-6M performance?


Here is some examples of highest Market Cap stocks, their markets and their performances over time.
