Elon Musk (@elonmusk) praised Jeff Bezos for committing roughly $28 billion of his own money to Blue Origin, saying he is glad the Amazon ($AMZN) founder remains deeply invested in space. “Bravo! I’m glad @JeffBezos cares so much about space,” Musk wrote on X after Bezos discussed his long-term financial commitment to Blue Origin. Bezos said he has invested the money over roughly 25 years as the company builds launch vehicles, engines and other space infrastructure. He also suggested Blue Origin could eventually pursue an IPO following its latest funding round involving outside investors. The comments come as competition between Blue Origin and SpaceX ($SPCX) continues to intensify. SpaceX has built a dominant position in commercial launches through Falcon 9 while expanding Starlink to more than 11,000 satellites. Starship also recently completed its first orbital flight during Flight 14. Blue Origin, meanwhile, has won NASA contracts tied to Mars exploration and continues developing its New Glenn rocket program. Musk also reiterated his much larger long-term ambitions for space infrastructure, saying he sees a path toward producing a petawatt of power annually. Those plans include large-scale lunar manufacturing, space-based compute infrastructure and systems capable of moving significant amounts of material beyond Earth. Musk has tied those goals to his broader vision of humanity eventually becoming a civilization capable of harnessing energy on an enormous scale.
