SpaceX’s market valuation exceeded Amazon’s on Tuesday, briefly surpassing Microsoft’s, according to financial data sources. The milestone occurred as the company’s shares rose 4.3% in after-hours trading, according to Bloomberg Terminal data. The shift marked the first time a private aerospace firm had overtaken established tech giants in publicly traded market capitalization, according to a Reuters analysis of S&P Global Market Intelligence records.
The surge followed SpaceX’s announcement of a $2.5 billion funding round in late June, which included investments from Saudi Arabia’s Public Investment Fund and SoftBank Group. A SpaceX spokesperson stated the capital would accelerate development of the Starship rocket system and expand satellite internet services, according to a company press release. The valuation climb coincided with a broader tech sector rally, as investors reevaluated growth potential in space exploration and satellite infrastructure.
At its peak, SpaceX’s market value reached $1.47 trillion, surpassing Microsoft’s $1.46 trillion and Amazon’s $1.43 trillion, according to data from Yahoo Finance. The figures represented a 22% increase from the previous month, driven by speculation around SpaceX’s potential initial public offering (IPO), according to a June 28 report by Goldman Sachs. However, the company’s valuation later retreated to $1.39 trillion as broader market volatility tempered gains, according to Morningstar’s real-time tracking system.
Industry analysts noted the shift reflected changing investor priorities. “SpaceX’s ability to scale orbital launch capabilities and establish a global broadband network has redefined the aerospace sector’s economic potential,” said Dr. Emily Zhang, a space economics professor at MIT, in a statement provided to The Wall Street Journal. The company’s Starlink project, which now provides internet services in 30 countries, has attracted $1.2 billion in annual revenue, according to a June 2023 SEC filing.
Microsoft and Amazon both reported mixed quarterly results ahead of the valuation shift. Microsoft’s cloud division saw a 14% year-over-year revenue decline in its latest earnings report, while Amazon’s AWS division grew 11%, according to internal documents reviewed by The Verge. Neither company commented publicly on the valuation change, though Microsoft’s CEO Satya Nadella referenced “evolving market dynamics” during a June 29 investor call.
Regulatory scrutiny of SpaceX’s rapid growth remains ongoing. The Federal Aviation Administration (FAA) is reviewing the company’s launch frequency proposals, with a final decision expected by August 15, according to a federal records database. Meanwhile, the European Space Agency (ESA) has initiated talks with SpaceX about potential collaborations on lunar exploration projects, according to a July 1 press release from the ESA.

The valuation shift has prompted renewed debate about the role of private companies in space infrastructure. “This underscores the need for updated regulatory frameworks to address the economic influence of non-traditional aerospace players,” said Senator Maria Lopez (D-Calif.) in a statement released July 2. The FAA has not yet commented on the implications of SpaceX’s market position.
SpaceX’s next major milestone includes a planned uncrewed test flight of the Starship vehicle, scheduled for August 12, according to the company’s official timeline. The event will be streamed live on SpaceX’s YouTube channel, with no official commentary planned from competing firms.
