Following disclosure of the filing, Amazon shares fell about 1.7% in premarket trading Tuesday, giving back a portion of the gains that followed the earnings announcement. Amazon exceeded Wall Street expectations during the second quarter, reporting earnings of $5.75 per share on $200.61 billion in revenue. Market observers, however, have long pointed to another destination for much of that capital: Blue Origin, the aerospace company Bezos founded to compete with Elon Musk's SpaceX. The latest Amazon stock sale follows reports that Blue Origin is seeking $10 billion in new financing at a $130 billion pre-money valuation. Beyond launch services, Blue Origin is pursuing several capital-intensive projects aimed at expanding its presence in the emerging space economy.
