NEW YORK, July 16 (Reuters) - Short sellers targeting SpaceX shares are sitting on an estimated $8.7 billion in paper profit since the rockets-to-AI firm's initial public offering last month, as its stock slipped below the IPO price, according to data and analytics firm Ortex Technologies.
Short sellers, who borrow shares to sell them and later buy them back at a lower price for a profit, have pressed their bearish bets on SpaceX as the company's shares slipped toward its IPO price of $135 from a post-IPO high of $225.64.
SpaceX shares have been volatile, experiencing brief bouts of strength before slipping back. On Wednesday, the stock dropped below its initial public offering price for the first time before recovering to close just above that level.
"SpaceX has been a rollercoaster for the short sellers, and it has ended up firmly in their favor," Ortex co-founder Peter Hillerberg said. "Rather than take profits, the bears kept adding the whole way down."
Almost half of SpaceX's tradable shares, about 49% of the free float, are now out on loan, according to Ortex.
"We believe most of that is short selling," Hillerberg said.
SpaceX did not immediately respond to a request for comment.
SpaceX's lofty valuation makes it a target for short sellers skeptical of its rich price tag, but strong retail and institutional interest as well as CEO Elon Musk's history of public battles against short sellers make bearish bets against the company a risky proposition.
The weakness in SpaceX shares reflects in part investor concern over debt-funded AI spending.
The stock's sizable short position could inject further volatility into the shares, with every dollar SpaceX shares move worth more than $300 million to the short side, Ortex estimates. That means the stock could swing hard in either direction.
SpaceX shares were up about 1% to $136.28 on Thursday.

Four leading AI models discuss this article
"Short-seller profits reflect sentiment and thin-float volatility more than definitive proof that SpaceX is overvalued at current levels."
The $8.7B paper profit for shorts on SpaceX (post-IPO at $135, peak $225.64, now ~$136) highlights acute valuation skepticism around its debt-funded AI capex. With 49% of the float on loan, every $1 move swings >$300M for the short base, amplifying volatility. Yet this ignores SpaceX's non-public Starlink cash flows, Falcon/Starship launch cadence, and Musk's track record of squeezing shorts (recall TSLA 2018-2020). The article treats secondary-market trading as a pure verdict on fundamentals; in reality, thin float + retail fervor can trigger violent short-covering rallies irrespective of earnings.
If AI-related leverage concerns prove warranted and launch cadence misses materialize, the short position could keep growing profitably; Musk's history of winning vs shorts is no guarantee when the valuation starts at 30-40x projected 2026 EBITDA.
"The extreme 49% short interest creates a high probability of a violent short squeeze that could trigger a rapid re-rating above the $200 level."
The 49% short interest on SpaceX (SPACE) is a massive liquidity trap, not just a valuation play. While the article frames this as a successful bear raid, the sheer volume of borrowed shares suggests a potential 'short squeeze' catalyst that could dwarf the current $8.7 billion in paper gains. With the stock hovering at the $135 IPO price, we are at a technical inflection point; if institutional support holds here, the cost-to-borrow fees will likely force a rapid covering cycle. The market is ignoring the asymmetric upside of Starlink’s recurring revenue, focusing instead on the noise of AI-related debt. This isn't just a stock; it's a high-stakes game of chicken between retail momentum and institutional shorts.
The bearish case is that SpaceX’s capital-intensive operations are fundamentally incompatible with a high-interest-rate environment, making the $135 floor a temporary illusion before a deeper correction.
"The article conflates short profitability with stock weakness, but the real risk is whether operational fundamentals can support the IPO valuation—short positioning is a volatility amplifier, not the underlying driver."
The $8.7B paper profit headline is a mirage masking a genuine structural problem: 49% of free float on loan suggests either massive short conviction or a liquidity trap. The real risk isn't short-seller losses (they're profitable now); it's forced covering if SpaceX delivers operationally. But the article buries the actual concern—debt-funded AI spending weakness—in one sentence. That's the real bear case, not valuation skepticism. A stock that can swing $300M per dollar moved is vulnerable to both capitulation rallies AND cascading liquidations. The IPO price bounce suggests institutional support, but that's fragile if Q2 guidance disappoints.
If 49% short float is real and shorts are already up $8.7B, many have likely taken profits or reduced size—meaning the 'powder keg' narrative overstates remaining short pressure. SpaceX's actual business (Starlink revenue, launch cadence, government contracts) may be strong enough to justify a re-rating regardless of short positioning.
"Despite $8.7B in unrealized short profits and a near-50% float on loan, the bear thesis is vulnerable to catalysts or squeezes that can reverse moves quickly."
Strongest takeaway: the piece foregrounds $8.7B in paper profit for short sellers and a 49% free float on loan, signaling plenty of volatility and the potential for a squeeze. But the narrative is incomplete: it treats short profits as directional proof rather than a dynamic of borrow costs and forced covers. Missing context includes SpaceX's cash runway and debt profile, what credible bullish catalysts would actually move the stock, and whether the public market will ever monetize AI or other franchises. Even with big short interest, a positive print—contract wins, financing news, or a squeeze—could snap the stock back sharply, complicating a pure bear case.
A positive catalyst or a short-squeeze could trigger a rapid upside reversal, making the bear case fragile. Paper profits don’t equal realized profits, and borrows can force abrupt covers at inopportune moments.
"High borrow fees and thin-float volatility amplify downside on operational misses more than upside from any near-term squeeze."
Claude's liquidity-trap framing misses that 49% borrow at these rates already prices in repeated failed squeezes. The $300M-per-dollar swing works both ways: any Starship delay or AI-capex miss will accelerate covering only after deeper drawdowns, not at $135. Real risk is sequential negative cash-flow surprises overwhelming Musk's retail halo, not binary institutional support.
"The high cost-to-borrow fees create a structural 'bleed' that forces short-covering even in the absence of positive operational news."
Grok, you're ignoring the cost-of-carry. When 49% of the float is short, the borrow fee itself acts as a massive 'tax' on the bears. If the stock stagnates at $135, the shorts bleed out daily, forcing a cover regardless of operational news. You’re looking for a fundamental catalyst, but the technical reality of the borrow market is a ticking clock. The 'liquidity trap' isn't just a theory; it's a mathematical inevitability for high-conviction shorts.
"Borrow fees matter only if operational outcomes remain ambiguous; operational surprises (positive or negative) dwarf carry costs in determining short behavior."
Gemini's borrow-fee math is sound, but assumes stagnation. Grok's right that 49% short at current rates already reflects expected bleed-out costs—shorts wouldn't maintain that size if daily carry was unsustainable. The real tension: if SpaceX operationally disappoints (Starship delays, Starlink growth slows), shorts profit faster than borrow fees drain them. Conversely, if operations accelerate, the fee becomes irrelevant noise before a violent cover. Neither side has priced in *which scenario* is likeliest.
"The real swing factor is the coherence between Starlink profits, launch cadence, and debt service; not a single forced-cover event."
Claude, I’d push back on the forced-cover risk as the sole bear-case driver. If macro funding tightens, high borrow fees could rather deter new shorts than force covers, and a durable Starlink cashflow could sustain a re-rating even with AI capex. The real swing factor is the coherence between Starlink profits, launch cadence, and debt service—operational risk timings vs borrow-cost dynamics matter more than a one-off cover event.
The panel agrees that SpaceX's high short interest (49% of float) creates significant volatility and potential for a short squeeze. However, they disagree on the likelihood of a squeeze and the primary risk factors.
Institutional support and operational acceleration could trigger a rapid short covering cycle, driving the stock price up.
Operational disappointments (Starship delays, Starlink growth slowdown) could lead to significant short profits and overwhelm Musk's retail support.
