Today SpaceX went public for the first time and raised a record $75 billion in the largest ever stock market transaction. The company’s stock was priced at $135 because it got so many people to buy it and they all had confidence that Elon Musk’s space exploration, satellite communications and AI-based innovation was going to be successful.

The IPO (listed on Nasdaq under the ticker SPCX) drew a global audience. SpaceX, unlike traditional offerings, gave a lot of stock to retail investors, democratizing access to one of the most eagerly awaited stock offerings in finance history. About 30% of the market value of the IPO was reserved for the average investor throughout the U.S., Europe and Asia, an event that is new in capital markets.
With a valuation of almost $1.77 trillion, SpaceX is now one of the world’s most valuable companies. The IPO will fund the expansion of the company’s Starlink satellite network, Starship, and the development of AI systems Musk has said will be crucial to the future of space missions. SpaceX has also better financial flexibility with which to carry out big projects without relying on government contracts.
Market analysts described this listing as a transformative moment for Wall Street and aerospace firms. The market size is considerably larger than the biggest-ever mega-IPO: Saudi Aramco and Alibaba. Investors get to sit in a company that has over the years pushed the boundaries of tech and innovation.
But there are risks in the IPO. SpaceX also depends heavily on large-scale projects, regulatory approval and geopolitical factors. And at the same time, there are big-picture challenges about when Mars colonization will be possible and how to scale that up and sustain it. Investor excitement is high, however, and at the start of trading SPCX shares were up.
Finally, SpaceX’s $75 billion IPO is a watershed moment in global finance. By combining record-breaking scale with retail investors’ participation in the company’s IPO, SpaceX has changed the way that most huge listings have implications for the way we think about how markets and industries are shaped by big companies.
