SpaceX has garnered huge enthusiasm among investors for its vision of sending AI data centres to space and even helping humans to colonise Mars.
Its listing raised $85.7bn and minted Musk as the world’s first trillionaire. Since first selling shares to the public at $135 each on Friday, they have risen to $209.
But analysts have questioned the sustainability of its high share price given the huge amount of uncertainty over its future earnings.
While Amazon is a household name, with its brand difficult to avoid being encountered on an almost daily basis, SpaceX is less embedded in the lives of the general public.
Despite SpaceX’s stock market value overtaking Amazon, the revenues and profits made by the companies are vastly different.
Amazon made $30.3bn of profit in the first quarter of 2026, while Musk’s future-focused SpaceX lost $4.3bn.
In 2025, Jeff Bezos’s firm accrued some $716.9bn in sales, while SpaceX recorded $18.67bn.
But investors appear to be betting on what they think SpaceX can acheive. While its biggest focus is the manufacture and launch of rockets with reusable parts, the company also manufactures and launches Starlink internet satellites, and is ramping up its presence in the AI race.
