Many readers are following SpaceX's upcoming initial public offering (IPO). It’s a great company, a tech leader that has revolutionized the launch industry, dropped the cost-to-orbit by 95%, and now leads the world in putting “mass” into space. 

And some readers think they can make some money from SpaceX…to which I say, “Good luck.” 

Okay, sorry if this comes across as downbeat, but hear me out. And to illustrate the point, I’ll begin with a discussion I recently had with a senior exec at a major aerospace firm. 

Talent Is Staying Put

“We’re hiring rocket people,” the man said. “Aerospace engineers. Mechanical engineers. Math, physics, materials science, every kind of geek; the whole range. But we can’t get anybody out of SpaceX right now. Nobody is quitting.” 

In just a few words, he captured the reality of the moment: SpaceX is no longer just another metal-bending aerospace company. It’s a gravity well for talent, a closed industrial ecosystem that has created its own market conditions and bent the rules around itself like a star can bend passing beams of light.

The guy I was speaking with is part of a major defense contractor that holds Pentagon contracts for missiles, testing, certification, and much more. 

And right now, the fact is that U.S. forces expended thousands of pieces of high-tech ordnance in Iran, and the Pentagon must restock, pronto. So, this defense company needs talent. They’re hiring. 

But SpaceX employees are not leaving. Higher pay and signing bonuses don’t move people. Nor do super-advanced projects in the defense sector. Generally, the answer to the defense firm’s outreach is along the lines of, “We love our country, but we’re not leaving SpaceX.”

At least, not yet. Not until after the dust settles from the IPO, it appears. 

All of this represents not just a hiring story. It’s a reminder that in key sectors of the economy, where engineering depth is scarce and timelines are unforgiving, the company that controls the best people can set the pace of the industry.

Another way to say it is that the SpaceX IPO has created an inflection point across aerospace and rocketry. Clearly, employees will wait until shares are issued, allocated, and vested, and only then might some consider leaving with a chunk of life-changing wealth in hand.

We’ve seen this before: recall those “Microsoft millionaires” of the early MSFT era, or “Amazon millionaires” of the AMZN rise. Now, it’s time for SpaceX employees to fill their boots.

SpaceX is Hard to Leave

SpaceX is an extraordinary company filled with capable and deeply motivated people. Its launch systems are remarkable, its space-based capabilities are formidable, and its execution is strong enough to make one of the world’s most difficult disciplines – yes, rocket science! – look almost easy if not routine. 

The fast pace of recent SpaceX missions only reinforces that impression. Indeed, as of early June, industry launch trackers have recorded 50 dedicated Starlink missions in 2026, with additional launches queued in a matter of days from now. Meanwhile, Falcon 9 boosters have flown for the 30th-plus time on repeatable schedules that would have seemed impossible only a few years ago.

SpaceX also benefits from what business school professors call a “competitive moat.” It’s not just that the company builds rockets; it has also built a tested and proven operating system for planning, logistics, launch, tracking, range safety, satellite deployment, and a global network scaled up to a point that competitors struggle to match.

Couple this company’s outstanding launch technology with its economies of scale and low cost per kilogram to orbit, and add in a world-class research and development capability, and you obtain a massive following for the upcoming IPO.

Valuation Risks

According to news reports, SpaceX is targeting an IPO price of $135 per share on June 12. Multiple reports describe the deal as an “all-primary” offering of roughly 555 million shares, which would make it the largest IPO ever if it clears at proposed terms.

At that level, the IPO could raise about $75 billion, implying a valuation of roughly $1.75 trillion to $1.8 trillion, depending on the final share count. That figure alone would place SpaceX among the world's largest companies on day one.

Indeed, for comparison, here are the current market caps of six other primary legacy aerospace firms:

Think about those numbers: yes, SpaceX is good, but is the company that good? That is, is SpaceX at a $1.8 trillion market cap all that much more valuable – by 80%! – than these other six companies put together, with corporate aerospace knowledge that goes back to the days of Werner von Braun, if not Robert Goddard? 

Meanwhile, the press releases are that less than 5% of total SpaceX shares will be released in the IPO, with the remaining 95% retained as treasury shares. And that’s exactly the idea.

That is, a relatively small public float for SpaceX will intensify demand. Funds, private offices, and eager-beaver investors will compete for a limited number of shares, driving up both the stock price and the company’s market cap.

Meanwhile, some SpaceX valuation models are far lower than the $1.8 billion number. For example, Morningstar recently published a value estimate of $780 billion, a huge number, but less than half the proposed IPO valuation. 

Obviously, this value gap matters big-time because outside buyers will be paying not simply for current SpaceX economics but for an enormous amount of future narrative and execution, while discounting the high-risk environment of orbital launch and space operations.

Recent coverage of the SpaceX filing indicates that the company’s Starlink system is the main profit engine, while other aspects of the overall company are capital-intensive and, only marginally profitable, if not money-losers. 

Under this framing, new public investors in SpaceX are being asked to accept a premium multiple not only on a market leader in space launches and satellite broadband, but also on an ambitious portfolio of adjacent bets whose payoffs are far less certain.

Looking ahead, it’s likely that SpaceX will IPO at a valuation well above what its underlying operations currently justify. And okay… perhaps the numbers will improve dramatically and fast; or maybe not. It’s quite a bet, whether for retail buyers or the whole economy. 

Money on Risky Autopilot

Apparently, SpaceX managers will take advantage of the investment system, namely that many passive funds are under pressure to buy shares as soon as they become eligible, to meet industry-standard benchmarks. And in this case, expect a share price run-up that will delay any near-term correction.

For many managers, having SpaceX in the book of holds will matter more than price moves or overall portfolio discipline. Indeed, NASDAQ is already moving toward faster inclusion for large new listings, while S&P Dow Jones has signaled greater resistance to rewriting long-standing seasoning and float rules. 

The result is a story about market structure that’s as important as the IPO itself; that is, the supply of shares may be limited, but the autopilot of buy-buy-buy demand is right up there in the final approach pattern.

Plus, as the SpaceX IPO unfolds, the offering will absorb historic amounts of capital. The effects will reach beyond the NASDAQ and surely force other markets, underwriters, and index managers to adjust their rules, procedures, and allocations to accommodate a company of this scale. 

That is, in a passive-investing system, once a company enters “the index,” many funds must buy it regardless of the company's underlying valuation. This is why a low-float, mega-cap listing is so unusual: price discovery will be shaped less by patient, deliberate analysis of real numbers than by a collision between structured, synthetic scarcity and autopilot mechanical demand.

Picks, Shovels, and Stress Tests

While many eyes will be on SpaceX, there’s a broader investment story here. A wide range of “picks and shovels” companies – businesses outside SpaceX but tied to the expansion of the space economy – will benefit from the IPO momentum. And we already see this in numerous related space plays, down to basic industries that supply metals and rocket fuel.

Another second-order effect is that index fund managers must raise cash or trim other holdings to make room for SpaceX, meaning the IPO’s influence will not be confined to one ticker. 

To buy-buy-buy SpaceX, managers will have to sell-sell-sell other names. And this will ripple through portfolio lists, sector weights, and benchmark tracking across the market. 

So, SpaceX is definitely disruptive, but not a market catastrophe. And no, it’s not the proverbial asteroid that will kill off the legacy aerospace dinosaurs. But expect to see stress test after stress test for many other companies in the space sector and adjacent. And we’ll likely see related effects on portfolio allocation systems designed in other eras, certainly from a time when companies rarely stayed private long enough to emerge at trillion-dollar scale.

A Gilded Age of Rockets

To me, at least, there is something distinctly Gilded Age about the SpaceX spectacle. Elon Musk is cast as a modern version of those swaggering industrial founders of another era: Rockefeller, Carnegie, Gould, Hill, and others from the days of steel, oil, and railways. 

Musk has not just built a big company that does rockets and stuff; he has concentrated the overall space-launch infrastructure in a way that forces institutions and even governments to respond. And the so-called “bullish case” for SpaceX actually carries a dark undertone: once a company becomes indispensable enough, the market doesn’t merely evaluate it; the market rearranges itself around it.

Between Musk personally, plus insider ownership, and private-capital networks that benefited from years of closed access, the advantages of the upcoming IPO appear to flow toward those already at the center. And outsiders – especially ordinary retail investors – are way back at the tail end of this train to glory. 

So, yes… SpaceX is a genuine technological marvel. It’s exciting. It has rebooted America’s space efforts out of the lethargic NASA model and has certainly taught lessons to bureaucrats within the Pentagon. And now, with the upcoming IPO, SpaceX is a case study in how twenty-first-century capital markets reward scale, scarcity, and narrative long before they reward broad participation. 

And as for retail? What if you just want to get a slice of the pie, a piece of the action? Well… the real lesson of this IPO is that in our new Gilded Age, the big-tall rocket ascending from the launch tower is not the only thing leaving the little guy behind.

That’s all for now. Thank you for subscribing and reading.
