SpaceX has overtaken Microsoft in market value, pushing the software giant to fifth place among the world's most valuable companies. The shift, based on private-share trading and recent funding rounds, marks a major milestone for the aerospace firm and signals a changing of the guard in corporate rankings.
The new top four
SpaceX now sits behind only the three largest publicly traded tech companies. Microsoft, which had held the fourth spot for months, dropped one rung. The exact dollar figures are not public because SpaceX is privately held, but analysts track its valuation through secondary market transactions and regulatory filings. The company's ascent reflects growing investor appetite for space-related ventures, even as traditional tech giants continue to post strong earnings.
How SpaceX's value grew
The company does not trade on a stock exchange, so its market value is estimated from private share sales and institutional investments. Recent rounds valued SpaceX at levels that pushed its total worth above Microsoft's market capitalization. The jump comes as the company expands its launch business and secures government contracts. Unlike Microsoft, which generates revenue from software, cloud services, and hardware, SpaceX relies on its rocket fleet and satellite network. The comparison underscores how differently investors now weigh industries that were once considered niche.
What the ranking means
Landing in the top five puts SpaceX alongside the most established names in global business. For a company that began with a series of rocket failures, the valuation milestone highlights the scale of its commercial success. Microsoft still leads in annual revenue and profit, but the market is betting that SpaceX's growth trajectory will outpace that of the older company over the long term. The shift also draws attention to the private-company premium—investors willing to pay more for stakes in firms that are not yet public.
The change in order raises questions about how long SpaceX can sustain its position. The company faces competition from rivals like Blue Origin and United Launch Alliance, as well as regulatory hurdles for its Starlink satellite network. Microsoft, meanwhile, is investing heavily in artificial intelligence and could see its own valuation climb again. For now, SpaceX holds the fourth slot—a spot that seemed unthinkable just a few years ago.
