Musk's SpaceX Files to Go Public in One of the Biggest IPOs

I had a change to get some pre-IPO exposure one year ago but hesitated at the time (and then forgot about it). In hindsight I might have missed some opportunity....

I visited NASA last year and even there people talk about SpaceX positively on their technology and vision.

Curious about the valuation and execution risk at this stage, but still seems there is a good amount of optimism.
