Wall Street spent six weeks betting against Elon Musk.
One in three tradable SpaceX shares is now sold short – $25 billion wagered that Musk fails.
But Elon Musk responded with seven words that told Wall Street sellers exactly how this ends.
The Warning Heard Across Wall Street
"The survival probability of firms who maintain a significant short position in SpaceX over time is very low."
That is the entire statement.
No press conference, no explainer, no hedging.
Just Musk on X, seven weeks after pulling off the largest IPO in stock market history, telling the people betting against him they are going to lose.
And he has been right before.

In 2018, Musk warned Tesla short sellers they had "about three weeks before their short position explodes."
Tesla went on to become one of the greatest short squeezes in market history.
The same crowd is now sitting on $25 billion in SpaceX short bets – 32% of the company's tradable float.
For context: Apple's short interest is roughly 1%.
What the Doubters Are Missing
SpaceX went public on June 12 at $135 per share, raising $85.7 billion.
The stock hit $225.64 on day three.
It has since plunged nearly 47% from that peak, and the bears think they have Musk cornered.
They don't understand what they're shorting.
Starlink – the satellite internet division Wall Street still treats as a side project – generated $11.4 billion in revenue last year.
That is 61% of SpaceX's total revenue, a share that climbed to 69% in the first quarter of this year.
Starlink now has 10.3 million paying subscribers across 155 countries, projected to reach 16.8 million by year's end.
Operating profit from Starlink alone hit $4.4 billion in 2025, more than doubling year over year.
This is not a rocket company with a money-losing internet experiment attached.
It is a global communications empire that happens to own the best rocket fleet on Earth.
Cathie Wood – the ARK Invest CEO who loaded up on Tesla when Wall Street called her delusional – went on Fox Business Wednesday morning and put it plainly.
"Think telecom," she told Maria Bartiromo. "That's been a very local business. In fact, the way to break into countries historically was to buy the [telecommunications companies]. No longer."
ARK has committed $80 million to SpaceX since the IPO and has not sold a single share through every downdraft.
ARK's long-term valuation case puts SpaceX at $2.5 trillion to $3.1 trillion by 2030 – meaning the stock would need to roughly double from current levels just to hit the low end of that range.
The Bears Are Walking Into the Same Trap
The short sellers have a real argument and it is going to cost them anyway.
Yes, a $116 billion share unlock is coming after the August 4 earnings report.
Yes, SpaceX posted a $4.9 billion net loss last year.
Yes, at current prices the stock trades at nearly 90 times trailing revenue.
But Musk's own 6.4 billion shares are locked until June 2027.
The largest seller in the company cannot sell.
Every share sold short right now has to be bought back eventually – at whatever price SpaceX is trading when that day comes.
The bears are betting a $116 billion unlock crushes the stock before Starlink's subscriber growth makes the current valuation look cheap.
Musk is betting Starlink gets there first.
He responded with seven words.
