I think Lockheed Martin is less leveraged than either SpaceX or Tesla. Also SpaceX just folded in several of Musk's companies that seemed questionably solvent. I really have zero clue how to value the resulting mess of liabilities and highly questionable revenue streams mixed with very solid ones, but $200B doesn't sound unreasonable. $1.6T sounds very high. My intention behind comparing to Lockheed Martin was to presume revenue would double for two consecutive years, which I viewed as reasonably charitable.
