What a find in the archives!

"It's quite amazing how this values SpaceX at 10bn, less than 50% of WhatsApp."

Somebody was wise a decade ago.

At the time Starlink was announced as was rocket reusability. Both were widely mocked and considered infeasible.

Since then Starlink has succeeded, reusable rockets are a reality, ISS crewed spaceflight restored to US.

I expect all that had an impact on the valuation. Personally I wouldn't invest in Elon because his stock is a wild ride but space x has achieved a lot.
