Elon Musk’s SpaceX made a historic entry into the public markets in June 2026. But while the IPO initially generated enormous excitement, another side of the story is now gaining attention — short sellers have reportedly made billions by betting against the stock.
According to published reports citing Ihor Dusaniwsky, head of predictive analytics at S3 Partners, short sellers have gained roughly $7.3 billion since SpaceX’s IPO. At the same time, bearish positioning against the company has expanded rapidly, with total short exposure reportedly climbing above $26 billion.
This is more than a simple post-IPO correction. SpaceX is now sitting at the intersection of extremely high valuation, limited public float, and massive future-growth expectations — a combination that can create both opportunity and significant risk for investors.
📉 From IPO Euphoria to a Reality Check
SpaceX completed its IPO on June 12, 2026, with shares priced at $135. The company attracted extraordinary investor attention, and its valuation surged beyond the $2 trillion mark during the initial trading period.
That kind of powerful debut naturally attracts momentum investors looking for continued upside.
But it also creates the perfect environment for contrarian traders to ask a different question:
Has the market already priced in too much future growth?
That question has become central to the S
$SPCXB investment debate.
A significant portion of SpaceX’s valuation is not based solely on its current earnings. Investors are also assigning substantial value to the long-term potential of Starlink, Starship, AI infrastructure, satellite networks, orbital data centers and the broader space economy.
When expectations become extremely high, even a small disappointment can trigger a major repricing.
🐻 Why Are Short Sellers Targeting SpaceX?
The bearish thesis is relatively straightforward.
When a stock rises rapidly on extraordinary expectations, short sellers often look for a disconnect between current valuation and realistic future earnings growth.
Recent reports citing S3 data indicate that around 206 million SpaceX shares have been shorted, representing roughly 32% of the publicly tradable float. The notional value of those short positions has reportedly reached approximately $25 billion.
That is a huge bearish position for a newly public company.
For investors, this is an important signal because such a high level of short interest can dramatically increase volatility.
But there is another side to the equation.
If
$SPCX delivers a major positive catalyst and the bearish thesis suddenly breaks down, short sellers may be forced to buy back their positions. That could trigger a rapid short squeeze, pushing the stock sharply higher.
⚠️ The Biggest Risk: A Crowded Short Trade
The more popular the bearish trade becomes, the greater the risk that it turns into a crowded trade.
Imagine a situation where a large percentage of traders are positioned for downside.
Then suddenly SpaceX releases stronger-than-expected results, announces a major government contract, reports powerful Starlink growth, or reveals a major AI-related commercial opportunity.
The same traders who were betting on a decline could suddenly become buyers.
That can create explosive upside momentum.
This is why shorting SpaceX may look attractive on paper, but in reality it carries significant risk.
💰 What Does the Reported $7.3 Billion Gain Really Mean?
The reported $7.3 billion gain is certainly a remarkable figure, but investors should understand what it actually represents.
A reported short-selling gain does not necessarily mean every short seller has already realized billions of dollars in cash profits.
Short-selling returns depend on factors such as when positions were opened, when they were closed, financing costs, and ongoing mark-to-market changes.
Therefore, the $7.3 billion figure is better understood as an indication of how profitable the bearish price movement has been for short positions since the IPO — rather than as a guaranteed realized cash profit for every short seller.
The bigger takeaway is that institutional bearish positioning around SpaceX has become unusually significant.
📊 What Should Investors Watch Now?
In my view, the most important question is not simply:
“Should investors short SpaceX?”
The better question is:
“Does SpaceX’s current valuation reasonably reflect its earnings potential, Starlink growth, AI infrastructure ambitions and long-term position in the space economy?”
That is where the real investment debate begins.
SpaceX is not simply another aerospace company.
Its Starlink business, launch infrastructure and growing connection with the broader AI ecosystem make it a far more complex investment story than a traditional space stock.
At the same time, those enormous future expectations create a major risk.
If execution slows, costs rise, or projected growth fails to keep pace with the valuation, the stock could face substantial multiple compression.
🔥 SpaceX Is Becoming a Bull-vs-Bear Battlefield
SpaceX is increasingly turning into a classic bull-vs-bear battleground.
Bulls believe
$SPCX .US could become one of the most important companies in the next generation of space technology, satellite internet and AI infrastructure.
Bears argue that the market has already priced in too much optimism following the IPO and that the valuation leaves little room for disappointment.
And the most interesting part is this:
Both sides have powerful arguments.
With SpaceX trading below its $135 IPO price in recent market conditions, part of the initial post-IPO excitement has already faded.
That creates a new stage for the stock — one where fundamentals, execution and valuation may matter more than pure IPO momentum.
🧠 My Investment Take
For me, the SpaceX situation highlights one of the most important lessons in financial markets:
A great company and a great stock price are not always the same thing.
SpaceX may have enormous long-term business potential.
But when an asset’s valuation already assumes extraordinary future success, investors must look beyond the company’s story and focus on the relationship between price paid and future growth.
At the same time, the reported $7.3 billion short-selling gain demonstrates something equally important:
Markets are never one-sided.
When investors become overly confident in a single narrative, contrarian opportunities can emerge.
However, SpaceX bears also face serious danger. With short interest reportedly reaching around 32% of the public float, a strong positive catalyst could quickly transform a bearish setup into a massive short squeeze.
🚀 Bottom Line
SpaceX’s IPO was one of the most closely watched market events in recent memory.
Now the second chapter is unfolding:
Valuation vs. fundamentals.
Bulls vs. bears.
Long-term vision vs. near-term price reality.
Short sellers have reportedly generated billions from the post-IPO decline, but the real test is still ahead.
The bigger question is whether SpaceX can deliver the extraordinary growth that investors have already priced into the company.
In this battle, the winners are likely to be the investors who look beyond the hype and focus on valuation, execution, cash flow and long-term growth potential.
