There are no dumb questions here. An IPO is an initial public offering, which is when a private company decides to "go public." It's a business and financial process that allows anyone, not just employees, to purchase shares of a company on a stock exchange, like the Nasdaq. 

During this process, companies have to disclose previously unpublished information about how their businesses operate -- how much money they make, how they spend it, what risks threaten their work and how they plan to address them. This information is vital to how Wall Street reacts; it determines the success of a launch. It also gives us new insights into how the business operates.

Once a company is public, it is required to publicly share its performance during quarterly earnings calls. These reports, especially recent ones from big tech companies, have been essential sources of light into the black box operations of rapid AI development, spending and future plans. The market's reaction to these reports is also a useful litmus test for understanding how we are all reacting to these changes.

Even if you never interact with SpaceX as a public company -- you don't own stock, you don't have Starlink internet or post on X -- the sheer magnitude of SpaceX's IPO means it will likely impact your life in one way or another. Most likely, SpaceX will become part of big index funds, where many people's retirement and pension plans are invested. So you may be unknowingly tying your financial future to the success, or failure, of Elon Musk's megacorporation.

Retail investors have placed over $100 billion in orders for SpaceX's upcoming IPO, underscoring strong interest in the company as it approaches what could be the largest public offering ever. Demand for SpaceX stock is significantly higher than the number of shares being sold, or roughly three to four times oversubscribed. 

Why? One reason is that SpaceX, which holds a dominant market share in the global commercial launch and satellite internet industries, has long been a private company. This is the first chance for most of the public to invest. 

But behind that is what Wall Street sees as massive growth potential. Goldman Sachs, the lead underwriter for SpaceX's planned public offering, projects SpaceX's AI revenue will skyrocket tenfold in the next several years, from $3.2 billion in 2025 to to $322 billion by 2030. Meanwhile, major industry reports, including those from Novaspace, project the broader global space economy to hit the $1 trillion milestone by 2034.

According to Karee Venema, senior investing editor at Kiplinger, that demand could be why SpaceX and CEO Elon Musk took an unconventional approach. SpaceX launched its IPO marketing by saying that it is selling 555,555,555 shares at $135 per share. Those optimistic projections for growth are probably why "investors are likely willing to pay such a premium for the IPO," Venema told CNET. 

But an oversubscribed stock, where demand heavily outweighs supply, comes with risks for investors, like increased volatility and large price moves in the shares once trading begins, according to Venema. 

High demand often causes a massive price "pop" on day one, followed by sharp drops when early investors cash out. There's also a degree of underwriter favoritism, where large institutional investors usually get priority over individual retail investors for the limited shares.

Venema also pointed to the so-called Musk effect, which refers to the sudden shifts in a company's valuation and public perception driven by Musk's personal actions, statements and overall branding. That phenomenon can be a double-edged sword, as seen in 2025, when Musk dedicated significant time to the Trump administration's unconventional Department of Government Efficiency, and Tesla's revenue and stock price fell sharply. 

That same Musk effect can generate unparalleled market enthusiasm and premium valuations. "Regardless of your personal feelings for Musk, he has done extraordinary things and a lot of folks want to be a part of it -- as evidenced by the excitement around the SpaceX IPO," Venema said. 

If you want to buy stock in SpaceX, Venema recommends you understand the dangers associated with IPOs and only buy shares with money you can afford to lose. First and foremost, talk to a financial adviser before investing.
