SpaceX has raised $75 billion in what CNBC is calling the largest initial public offering on record. The company sold 555.6 million shares at $135 each, with its stock set to begin trading on the Nasdaq exchange.

No company has ever pulled in this much money through a single public offering. The sheer dollar figure resets expectations for how big a market debut can get — and it puts SpaceX in rare company alongside the most valuable technology firms on the planet.

But the deal's reach may extend much further than the headline investors. According to Wired, many ordinary Americans could find themselves as SpaceX shareholders without ever consciously choosing to be. When a company this large goes public, its shares tend to get absorbed into broad index funds and exchange-traded funds — the same vehicles that sit quietly inside millions of 401(k) retirement accounts. If you invest in a diversified fund, there is a real chance SpaceX will land in your portfolio automatically.

The Nasdaq listing is itself a statement. Nasdaq is home to Apple, Microsoft, and Amazon — companies that define what a technology giant looks like. SpaceX's debut at this valuation signals that the commercial space industry has arrived at a similar scale.

Why it matters: The record-breaking IPO doesn't just reward early backers — it could make millions of everyday retirement savers unwitting stakeholders in the future of spaceflight.
