Michael Burry sees a $3 trillion problem with SpaceX

SpaceX already nailed its first test stock market test.

The tough question is whether investors can detach the stock from the company.

Elon Musk’s rocket, satellite, and artificial intelligence company has become one of the most controversial new listings on the market after a record-breaking initial public offering and rapid ascent. The company’s story is huge. Its valuation may be even bigger.

That’s why Michael Burry’s warning of late has such weight. Not only is SpaceX (SPCX) overpriced, he says, but the bearish trade may also be as dangerous as the bullish transaction.

“I am not involved with SpaceX now. Neither short nor, ahem, long,” Burry wrote, according to Fortune.

SpaceX is no longer just a rocket story

The secret message in Burry’s SpaceX comments isn’t that a famous skeptic believes a hot stock seems expensive.

The more useful investing conclusion is that SpaceX has quickly become a market structure tale. The stock is locked between two forces that can punish retail investors: a value that may already be priced in years of faultless execution and a fan-driven trading setup that can make shorting the company excruciatingly expensive.

That makes this case different from a normal IPO argument. SpaceX is not being valued as a launch company. And investors are baking in Starlink, government contracts, satellite broadband, defense work, AI infrastructure, Musk’s brand, and long-term goals that reach far beyond Earth.

That is a powerful compilation of stories. It’s also hard to put a price on.

SpaceX’s IPO was priced at $135 a share, Reuters indicated, raising $75 billion from the sale of 555.56 million shares and valuing the corporation at $1.77 trillion. The IPO made SpaceX the biggest in U.S. history.

Even before investors had a long public earnings call history, segment margins, or quarterly cash-flow performance to assess, SpaceX was one of the most valuable corporations in the market. SpaceX might even be one of the greatest publicly traded corporations in history.

But even well-regarded companies can be difficult investments when the stock price asks investors to pay up front for a future that’s still years away.

Burry skeptical of SpaceX valuation, recommends restraint

Burry’s statement heightens that tension because he did something more interesting than merely criticize SpaceX.

He declined to act on the trade.

Burry also released details on SpaceX put options that would let investors to bet against the shares. He was “tempted” but finally declined, he claimed.

That is the story of this constraint.

Put options give investors the right to sell a stock at a fixed price before a fixed expiration date. While these options are one of the most popular tools investors use when predicting a company will fall, they are not free.

Put options can be expensive when a stock is volatile, popular, and hotly contested. So an investor can be accurate that a stock is expensive and still lose money if the decline occurs too late, doesn’t go far enough, or occurs after the option has expired.

That is the trap Burry seems to be avoiding. He has questioned SpaceX’s valuation, pointing to a corporation that still makes far less money than its value on paper would indicate. The discrepancy is so large that it makes the stock hard to evaluate, but that’s typical for a high-growth corporation.

More important to retail investors than a spectacular bearish call are Burry’s cautions. He essentially says the stock might be too expensive to purchase and too structurally hazardous to short. The unique setup usually signifies that the risk lies not only in the basics but also in the trade itself.

The one thing all SpaceX bulls should be concerned about is the company’s need to grow into a massive valuation.

Another difficulty for SpaceX is that demand driven by Musk, the limited supply of shares, index speculation, and expensive options might sustain a heavily priced company longer than valuation models would predict.

So the best lesson to take from Burry’s words is not to “buy” or “short.”

It’s that SpaceX could be entering the kind of territory where belief matters less than time, position size, and risk control.

What SpaceX investors should watch next

The next big SpaceX stock catalyst may not be a rocket launch. It could be a supply of shares.

After the IPO, just around 4.3% of SpaceX’s shares were available for public trading. The rest was locked up. Elon Musk’s approximately 42% stake is locked until June 2027.

Key takeaways

Michael Burry is questioning SpaceX’s valuation, but he says he is not long or short the stock, according to CNBC.

His restraint may be more important than his skepticism because it suggests the bearish trade is difficult.

SpaceX’s valuation reflects rockets, Starlink, defense, artificial intelligence, and Musk’s long-term vision.

A tight public float can support the stock in the short term but create risk as more shares unlock.

Put options may be expensive because traders already expect extreme volatility.

Retail investors should watch lockup expirations, first earnings reports, and whether SpaceX can justify its valuation with public-company fundamentals.

This is essential because a tight float can make a hot stock look better than it is.

There are not enough shares to trade and the price might be driven up quickly by enthusiastic purchasers. It may seem like it has no end to its ambition. But it can also stifle the true price discovery that happens when more insiders and early investors get to sell.

So the lockup calendar is significant.

SpaceX’s number of shares could explode in the next six months. As of December, the company’s available equity, excluding the locked-up stake owned by Musk, may be as high as 58%.

This is an event that ordinary investors should not miss.

If SpaceX demand remains intense, the market may absorb those shares. If enthusiasm cools, the added supply could pressure the stock and shift attention back toward financial fundamentals.

The first earnings reports will also be key. Now SpaceX has to transition from private market legend to public corporate operator. Investors will be looking at revenue quality, earnings trajectory, cash burn, Starlink economics, government-contract exposure, and whether the company’s artificial intelligence goals can become more than a valuation enhancer.

The risk is not that SpaceX lacks ambition. The risk is that the stock already prices in too much of it.

SpaceX may be too expensive to buy and too hard to short

Burry’s warning against SpaceX fails because he’s too high-profile. Yet it works because it gets the toughest part of the trade.

SpaceX is arguably an extraordinary company, with a solid position in commercial launch, a strong Starlink business, and a founder who can translate long-term ambition into demand that moves the market. That doesn’t automatically make the stock a buy at any price.

At the same time, valuation alone probably doesn’t make SpaceX a clean short.

A stock connected with Musk, scarcity, index speculation, and massive retail demand can continue to climb long beyond the point when traditional investors consider it too expensive.

That’s why the real narrative is Burry’s restraint. He is not telling investors that SpaceX is just a bubble. He wants something a little more refined. A stock that both optimistic and bearish bets could cost if investors forget about timing and structure.

For retail investors, that might be the most essential takeaway. SpaceX’s story isn’t just about delivering rockets to orbit anymore.

The question is whether the stock can stay there once the market starts looking more closely at the business behind it.
