Musk: Moon, Mars factories could create quadrillionaire wealth

Elon Musk responded to a social media post that calculated he is about $998.9 trillion short of $1 quadrillion. He wrote that reaching quadrillionaire status is ‘not impossible’ but ‘definitely requires factories on the Moon and Mars to achieve.’ He added, ‘By then, I don’t think dollars will be used as currency. Just mass and energy.’

The exchange noted that Earth-based activity alone could not reach that scale.

SpaceX reported $18.7 billion in revenue for 2025 and has publicly projected it could reach $1 trillion in revenue by 2030. The company staged a $2 trillion IPO debut on Nasdaq that briefly ranked it as the sixth most valuable U.S. firm.

Musk’s SpaceX compensation package ties 200 million super-voting shares to establishing a permanent Mars colony of at least one million people. SpaceX has selected a Mars flyby crew, with one seat reportedly filled by a cryptocurrency billionaire. Musk also joked about finally securing the ‘volcano lair’ he has referenced previously.

Musk framed future value in physical terms, saying mass, raw materials and energy could replace dollars as the basis of exchange in an economy spanning multiple celestial bodies. He linked those remarks to the limits of accumulation confined to a single planet and to SpaceX’s stated growth and settlement targets.
