Is SpaceX really going public? Should Tesla shareholders be happy or worried?

If the asset Musk is best at telling stories with suddenly becomes publicly tradable too, will Tesla get drained, or will the entire Musk empire get lifted together?

This is not a normal space news item—it’s a reshuffling of Musk’s capital empire.

For a long time, when people bought Tesla, they weren’t only buying EVs. They were buying Musk, FSD, Robotaxi, Optimus, energy storage, real-world AI, and that crazy-sounding but repeatedly dragged into reality by Musk, super-future story.

But now the market suddenly has a new ticket.

Before, if you wanted to bet on Musk’s future, Tesla was the most direct public-market choice. If SpaceX really goes public, investors get another option: one company runs cars on the ground, talking autonomous driving and robots; the other launches rockets into the sky, talking Starlink, satellite internet, and space infrastructure.

That raises the question.

When a scarcer, more mysterious, and more emotionally charged SpaceX is put in front of Wall Street, will capital still treat Tesla as the sole core asset of the Musk empire?

Today we’ll get to the bottom of it. Why SpaceX’s IPO is not just about aerospace stocks, but also about Tesla’s valuation logic. Is it a booster for Tesla, or a new black hole that pulls money away? And what should ordinary investors look at to tell whether this is a new round of revaluation for the Musk empire, or just another super-high-valuation sentiment frenzy?

SpaceX IPO scale: a $1.75 trillion valuation

According to the latest reports, SpaceX plans to price its IPO at $135 per share, target a raise of about $75 billion, and value the company at around $1.75 trillion. If that really happens, it would become one of the biggest IPOs in history, and could even sit right next to America’s top tech giants.

Listen to that number—$1.75 trillion. What does it mean? It’s not that a company is lifting off from Earth; it’s that the valuation itself is being launched into orbit.

Tesla’s market cap is about $1.48 trillion today, with the stock around $418 and a P/E ratio near 384x. In other words, if SpaceX goes public at that target valuation, it won’t be coming in as Tesla’s little brother. It would stand in the same weight class as Tesla, and could even surpass Tesla in market-cap imagination.

That’s the core issue Tesla shareholders need to watch.

In the past, when the market looked at the Musk empire, Tesla was the brightest public-market window. If you wanted to buy Musk’s future, Tesla was the only way. Tesla therefore enjoyed a huge narrative premium. Its automotive gross margin was under pressure, the EV price war was intense, and FSD and Robotaxi were still being checked in the real world—but the market was still willing to give Tesla a lofty valuation. Why? Because people believed Musk had more than cars—he had the future.

But once SpaceX goes public, things get more complicated.

Two possibilities: capital synergy vs. capital diversion

The first possibility is capital synergy.

If SpaceX goes public and becomes a blockbuster, the market will say Musk once again turned the impossible into a capital-market event. Rocket recovery used to sound crazy; now it’s standard commercial space practice. Global satellite internet used to sound like a distant story; Starlink is already one of SpaceX’s most watched monetization assets.

If SpaceX successfully lands on the U.S. market, investors may get excited again and decide that the whole Musk ecosystem deserves a fresh re-rating. At that point, Tesla could get pulled higher too.

That’s called Musk premium spillover.

Think of it like a star director’s new movie doing huge box office numbers, which makes people go back and revisit his old franchises. If SpaceX makes the market believe in Musk’s execution again, Tesla’s Robotaxi, Optimus, FSD, and energy storage stories may also get a fresh sentiment boost.

The second possibility is capital diversion. This is more dangerous for Tesla.

If SpaceX becomes extremely hot after listing—especially if retail and growth funds pile in—some of the Musk-narrative capital that used to sit in Tesla may get pulled away. In the past, people bought Tesla because it was the only publicly tradable Musk super-future asset. Now that SpaceX is also buyable, investors will ask: if I want to bet on Musk’s starry future, why must I buy Tesla in the EV price war?

That sounds harsh, but it’s real.

Tesla’s problem now is that it’s no longer a clean single-growth story. It has auto-cycle exposure, pricing wars, China competition, Europe demand, FSD safety controversy, Robotaxi commercialization pressure, Optimus production uncertainty, and $25 billion-plus in AI and manufacturing investment. It’s strong, but it’s also complex.

SpaceX’s story, at least at the time of listing, may be easier to package as a purer future-tech asset: rocket launches, satellite internet, AI, space infrastructure, defense space. Every one of those words looks like a glowing headline in a Wall Street banker’s deck. It doesn’t need to explain every day whether Model Y prices are being cut, and it doesn’t need to be asked whether Europe sales are just a low-base rebound.

So the short-term effect on Tesla cannot simply be called bullish or bearish. More accurately, SpaceX’s IPO will push Tesla into a new era of comparison.

Before, the market asked: is Tesla really worth this much? Now the market will ask: among all Musk assets, is Tesla still the one worth buying most?

That line matters a lot.

The real focus: a new ranking among Musk assets

So here’s the real point. Is SpaceX paving the way for Tesla, or is it stealing money from Tesla? Like and subscribe, and let’s keep unpacking.

If SpaceX performs strongly after listing, Tesla may get pulled along—but it may also be outshone. If SpaceX opens high and then fades, the market may swing the other way and worry that the Musk story is not an endless cash machine, which would drag sentiment across the whole Musk concept.

So what the IPO really brings is not just stock-price movement, but a re-ranking among Musk assets.

It’s like a conglomerate suddenly spins off its most mysterious, most imaginative, and best-storytelling business as a separate listing. Existing shareholders are happy because the whole group gets more exposure. But they’re also nervous, because the market can now start assigning a separate price tag to each business. Once that happens, who is the real crown jewel and who is just a bonus story inside a rich valuation becomes much clearer.

From today’s market perspective, the timing is delicate.

Around early June, the U.S. AI theme is still alive, but capital is clearly more selective. Barron’s noted that Tesla’s Robotaxi made progress, yet the stock didn’t respond with excitement and instead slipped to around $418. In other words, the market no longer applauds Robotaxi blindly just because it hears the word. It starts asking about scale, revenue, fleet size, and when it will actually hit the income statement.

Viewed together with the SpaceX IPO, that becomes even more interesting.

• On Tesla’s side, Robotaxi is moving in Austin, but the scale is still small. FSD is improving, but it still has to pass safety and regulatory tests. Optimus has huge imagination value, but it still needs to move from stage demos to factories and then into earnings. Energy storage is more concrete, but it hasn’t fully taken over the valuation banner yet.

• On SpaceX’s side, the story is just about to go public, yet the valuation is already being thrown around at $1.75 trillion. The market is excited, but it will also ask: isn’t this price already baking in many years of future success?

So the focus of this episode is not saying SpaceX will definitely steal money from Tesla, nor that SpaceX will definitely lift Tesla. The real point is:SpaceX’s IPO forces every investor to rethink one question—how should the Musk empire actually be valued?

What it means for ordinary investors: re-breaking down Tesla’s valuation

So what’s the real value for regular investors?

The most direct benefit is that it forces you to break Tesla’s valuation back apart. Before, many people just said, ‘Tesla has Musk, so long-term it must be great.’ That’s too crude. With SpaceX in the picture, the market will split that logic into finer pieces.

Where exactly is Tesla expensive? Is it the auto base, FSD, Robotaxi, Optimus, energy storage, or Musk’s personal brand? If you look at these separately, which ones are already making money, which are still burning cash, which can show up in the earnings report, and which are still just conference-stage imagination?

That’s good for investors. Because you no longer have to drink the whole soup of future stories at once. You can distinguish:

• Cars are the cash-flow base

• FSD and Robotaxi are the valuation ceiling

• Optimus is a long-dated option

• Energy storage is a second growth curve closer to earnings

• And SpaceX may become another completely independent super asset in Musk’s ecosystem

Even more importantly, if SpaceX really starts trading, you can no longer just watch Tesla on its own—you also need to watch how Tesla and SpaceX move together.

• If SpaceX rallies hard and Tesla also rises, that means the market is trading Musk-ecosystem synergy.

• If SpaceX rallies hard but Tesla doesn’t—or even falls—then capital may be rotating internally among Musk assets.

• If SpaceX opens high and then fades, and Tesla gets dragged down too, that means the market is starting to cool on high-valuation stories again.

That’s much more useful than just staring at Tesla’s daily change.

Long-term meaning of SpaceX: from ground AI to space AI

There’s another longer-term layer that’s easy to miss.

SpaceX is not a normal rocket company. It connects rocket launches, satellite manufacturing, Starlink satellite internet, ground terminals, defense space, AI infrastructure, and communications services—and may eventually extend into space manufacturing and orbital computing. The chain is long, and many parts have been hard for ordinary investors to access.

SpaceX going public will make the market look at these ideas again.

That’s good for the U.S. tech theme. Over the past two years, a lot of money has crowded into Nvidia, semiconductors, data centers, power, and AI software. If SpaceX lights up space infrastructure, the market may expand from ground AI to space AI. In other words, AI may not only run in data centers; through satellite networks, global connectivity, edge computing, defense systems, and space communications, it could enter a much bigger infrastructure narrative.

That layer is the easiest part of a normal IPO story to overlook.

SpaceX’s listing doesn’t simply let people buy rockets; it may change the market’s understanding of what an ‘infrastructure AI company’ is.

Why say that? Because no matter how smart AI gets, it can’t live forever inside a data center. For models to enter the real world, they need three things: compute, endpoints, and connectivity. Nvidia solves compute, Tesla solves ground endpoints—cars, robots, and storage devices are the hardware where future AI can act. SpaceX’s special role is that it may solve connectivity.

If Starlink keeps expanding, it won’t just connect ordinary home broadband; it could connect airplanes, ships, remote areas, battlefield communications, unmanned systems, and even a huge number of future mobile devices. In other words, what SpaceX sells on the surface is satellite internet, but underneath it may be the neural network of real-world AI. From that angle, SpaceX is no longer just a rocket company, but an infrastructure company bringing AI from servers to every corner of the planet.

• Nvidia sells compute.

• Microsoft and Amazon sell cloud platforms.

• Tesla wants to put AI into cars and robots.

• SpaceX wants to spread connectivity across the sky above the whole Earth.

If Starlink keeps expanding, it’s not just broadband—it could be the connectivity layer for remote regions, oceans, aviation, military communications, unmanned systems, and even Robotaxi and robot networks.

If you view the Musk ecosystem together:

• Tesla handles ground endpoints—cars and robots are mobile hardware.

• SpaceX handles the sky network—satellites and rockets are infrastructure.

• xAI handles the model and the brain.

• Energy storage handles power and energy.

If these pieces truly connect in the future, then what the market is talking about won’t just be EVs or rockets, but a full real-world tech network spanning energy, intelligent endpoints, AI brains, and global connectivity.

Of course, that sounds thrilling, but investing is not about how thrilling it sounds. Rocket fuel is thrilling; your brokerage account doesn’t need to burn with it.

So don’t just watch the excitement in this episode—save it first. The risks below will determine whether this is an opportunity or just a firework show of high valuations.

Risks you cannot ignore

First risk: SpaceX’s valuation is too high, leaving too little room for error.

$1.75 trillion is not a normal valuation. This price means the market has already bought in a lot of future success. If future revenue growth, Starlink profitability, launch-business margins, or the AI story all come in below expectations, the stock could swing violently. MarketWatch has already warned that this level of valuation leaves very little room for mistakes.

Second risk: the higher the retail participation, the more volatile the early trading may be.

Reports say SpaceX may give retail investors a larger allocation this time. That sounds fair, but higher retail participation also means early trading could become more emotional. A lot of people won’t be buying because they understand cash flows—they’ll be buying because they see Musk, rockets, and the biggest IPO ever. That kind of trading can rise very fast, but it can also fall very fast.

Another risk: SpaceX may not enter the S&P 500 quickly.

S&P Dow Jones has already said it won’t break existing inclusion rules just because SpaceX is huge. In other words, the dream of ‘massive passive buying right after listing’ may not happen that quickly. It may enter some other indices first, but inclusion in the S&P 500 still depends on profit, public float, and the rules.

That matters, because many retail investors love to imagine index funds will immediately step in. If passive money doesn’t arrive fast enough, short-term prices rely even more on active capital and sentiment.

Further down the list: Tesla could face capital diversion, and that risk cannot be ignored.

This isn’t saying Tesla is bad. It’s saying capital always has to choose. Growth-stock capital is not unlimited. If SpaceX steals a huge amount of attention after listing, Tesla may be ignored in the short run. Especially when Tesla’s own Robotaxi, FSD, and Optimus still lack stronger evidence, capital may say: if I’m buying future stories anyway, why not buy the fresher one?

Finally, the Musk attention discount will be discussed again.

The thing Tesla shareholders fear most is not that Musk lacks imagination, but that he has too much of it. Tesla wants Robotaxi, SpaceX wants Mars, xAI wants models, Optimus wants mass production, and energy storage wants expansion. Each is a super project; each could be its own movie. The problem is, a CEO only has 24 hours a day. Wall Street will ask: can Musk really push all of these to the point of delivery at the same time?

A new investment framework: focus on three lines

So what we’re bullish on here is not ‘SpaceX goes public and Tesla must rise.’ That’s too simplistic.

What I think is more important is that SpaceX’s IPO opens a new investment framework. In the future, when you look at Tesla, you can’t just watch EV sales. You need to see what role it plays in the Musk ecosystem. Is it a cash-flow engine, an AI endpoint platform, a Robotaxi network, or a real-world AI node being redefined by SpaceX and xAI?

Longer term, the biggest market benefit may be that U.S. stocks shift from a single AI theme to multiple tech narratives.

In the past, when the market talked AI, the first reflex was Nvidia. Then it spread to Broadcom, AMD, data centers, power, storage, and software. If SpaceX’s IPO succeeds, the next phase could expand into satellite internet, defense tech, space communications, automation systems, edge AI, and orbital infrastructure.

So what should you watch going forward? Three lines:

1. Keep watching the linkage between Tesla and SpaceX. If Tesla rises with SpaceX after the IPO, that means Musk-ecosystem synergy is in play; if Tesla gets suppressed, that suggests capital is rotating out. That signal will be very valuable.

2. Watch Tesla’s own ability to deliver. No matter how big SpaceX is, it can’t expand Tesla’s Robotaxi fleet, raise FSD subscriptions, put Optimus into factories, or make energy storage contribute profits. If Tesla wants to keep its high valuation, it has to keep producing results.

3. Follow the Musk ecosystem through the industrial chain. Satellite communications, AI compute, robot components, energy storage, power infrastructure, and autonomous-driving hardware may all be rediscovered by the market. Not every concept will rally, but companies with real orders, real moats, and real cash flow will be more likely to attract capital.

Conclusion: the beginning of revaluation

So by now the answer is pretty clear.

SpaceX’s mega IPO is neither simply bullish nor simply bearish for Tesla. It’s more like a mirror, making Musk’s capital empire clearer. In the past, Tesla alone carried too many Musk-future stories; if SpaceX goes public, the market will start to divide labor, compare, and reprice.

• Short term, Tesla may become more volatile.

• Mid term, capital may rotate between SpaceX and Tesla.

• Long term, if the Musk ecosystem can truly link AI, energy, autonomous driving, robots, and satellite communications, Tesla could actually gain even more room for imagination.

But the prerequisite is: the story must become evidence. Robotaxi has to expand the fleet, FSD has to cut interventions, Optimus has to enter factories, energy storage has to show up in the earnings report, and SpaceX has to prove it deserves a $1.75 trillion valuation.

One sentence: SpaceX’s IPO is not the end of the Tesla story; it’s the beginning of a revaluation of the Musk empire. Whether Tesla gets drained or gets lifted will depend on whether the market sees SpaceX as a new toy, or as the engine upgrading the entire Musk ecosystem.
