Tesla shorts on edge following $1.1 billion loss
Tesla (NASDAQ:TSLA) short-sellers are down $1.1 billion in mark-to-market losses after TSLA stock rose 9.7% on Wednesday. The surge in the electric car and energy company’s shares comes on the heels of a successful 2018 Annual Shareholder Meeting, where CEO Elon Musk expressed an optimistic outlook in the Model 3’s production and Tesla Energy’s budding energy storage business.
Tesla is currently the most-shorted U.S. equity and the most-shorted stock worldwide in the Automobile Manufacturing Sector, with 37.7 million shares shorted and $11 billion in short interest as of Wednesday, according to a recent report from S3 Partners. Over the first five months of 2018, Tesla shorts saw substantial returns, up $572 million or 5.53% in mark-to-market profits. Since May 22, however, Tesla short-sellers are down $1.7 billion in mark-to-market losses as the company’s shares rose by 16.6%, turning a profitable year into the third straight year of Tesla short-selling losses. Wednesday’s 9.7% rally generated $1.1 billion in mark-to-market losses for $11 billion of TSLA short interest.
Overall, the financial technology firm expects Tesla’s short interest to decline as some short-sellers cut their positions after incurring $1.1 billion in mark-to-market losses. Considering the conviction that has been exhibited by dedicated Tesla shorts over the years, however, analysts at S3 Partners expect that a significant number of short-sellers will still hold on to their positions.
Tesla’s long-term investors are now looking to the company’s stock reaching $350 per share as the company achieves its target of producing 5,000 Model 3 per week by the end of Q2 2018 — a milestone that Musk dubbed during the recently-held Annual Shareholder Meeting as “likely” to happen.
Wednesday’s 9.7% rally stands as Tesla’s biggest percentage gain since November 4, 2015. The stock closed at $319.50, marking the best close of the company’s shares since March 16 this year and making it the best performer on the Nasdaq 100 during Wednesday’s trading.
Apart from Musk’s optimism regarding the production numbers of the Model 3, a critical factor that appears to have resonated among Tesla’s shareholders was the company’s growing energy business. Earlier this week, Tesla CTO JB Straubel stated that the company has managed to deploy 1 GWh of energy storage worldwide to date. During the 2018 Annual Shareholder Meeting, Elon Musk noted that in less than a year, Tesla would be able to do another Gigawatt project, followed by even more growth in the years to come.
“In less than a year from now, we will do another Gigawatt (project). The rate of stationary storage deployment is going to grow exponentially. For many years to come, each incremental year will be about as much as all the preceding years, which is a crazy, crazy growth rate,” Musk said during the Annual Shareholder Meeting.

Elon Musk predicted a “short burn” after the company’s now-infamous Q1 2018 earnings call. In a series of updates on Twitter, Musk reiterated his expectation that Tesla would start seeing profits sometime in Q3 or Q4 2018, while stating that the “short burn of the century” would be coming soon. During that time, Musk noted that the deliveries of the Boring Company’s “Not-a-Flamethrowers” would come just in time. Interestingly, a handover party for the first 1,000 Not-a-Flamethrowers is set for this coming Saturday, June 9, at Los Angeles, just a few days after Tesla shorts took a $1.1 billion blow.
As of writing, Tesla stock is trading down 0.32% at $318.49 per share on Thursday’s pre-market trading.

SpaceX stock did the opposite of what most of Wall Street expected this week, when the day designed to be its most dangerous turned into a rally, and the rally kept going.
Thursday marked the first major lockup expiration since SpaceX’s June IPO, making roughly 911.5 million insider held shares eligible to trade for the first time, more than doubling the company’s public float. Analysts and short sellers had spent weeks bracing for a flood of selling, especially after the stock fell 13 percent following its first earnings report as a public company on Tuesday. Instead, shares rose 6.1 percent Thursday to close at $114.92, and by Friday they were trading near $129, up more than another 12 percent on the day.
SpaceX shorts get warned by Musk ally, echoing Tesla’s early struggles
The setup made the outcome notable. Short interest had climbed to roughly 34 percent of the float heading into earnings, among the highest of any large cap stock, with about 95 percent of available shares to borrow already on loan. CEO Elon Musk warned short sellers twice in the weeks before the lockup, writing on X that “the survival probability of firms who maintain a significant short position in SpaceX over time is very low,” then following up on the morning of earnings with “I try to warn them, but they just double down.”
When the newly unlocked shares hit the market and the selloff never showed up, some of that short position appears to have started unwinding. TipRanks reported that options activity shifted toward bullish strategies like put selling and risk reversals following the rally, with roughly $600 million in options premium trading Thursday alone. Retail buyers also stepped in during the earnings dip, according to Vanda Research.
The fundamentals behind the stock have not changed much in a week. SpaceX’s revenue nearly doubled year over year to $7.8 billion, with Starlink subscribers doubling to 12 million and the company’s AI segment growing 247 percent. What spooked investors on Tuesday was the spending side. Capital expenditures jumped to more than $18 billion for the quarter, up from $2.8 billion a year earlier, with AI investment alone rising from $749 million to $15.8 billion. Wall Street remains split on whether that spending is building infrastructure SpaceX needs or outrunning what the business can currently support, a debate Teslarati has tracked since shares first came under pressure.
None of that resolves the bigger question hanging over the stock. Thursday’s release was only the first of nine staggered lockup tranches, with roughly $800 billion worth of additional shares scheduled to become eligible through October, and Musk’s own stake stays locked until next June. If this week is any indication, the market is treating that supply as something it can absorb rather than something to fear, at least for now.

Tesla Cybertruck production snaps back after ugly supplier fight
Cybertrucks are piling up again at Giga Texas after Tesla’s court win against a parts supplier.
Cybertruck production at Giga Texas is showing its first visible recovery since Tesla sued a supplier last month over withheld manufacturing tooling.
Aerial observer Joe Tegtmeyer flew over the Austin factory Wednesday morning and counted roughly 100 or more Cybertrucks filling the outbound lot, a sharp jump from the thin numbers seen in recent weeks. The flyover came a day after a judge granted Tesla a temporary restraining order against Angstrom Automotive Group, the parts supplier at the center of the dispute.
Tesla filed an emergency lawsuit in late July after Angstrom told the automaker it planned to close the Troy, Texas facility where Tesla’s die-cast tools, trim dies and other Cybertruck stamping equipment were housed. According to Tesla’s complaint, a shipment of 700 finished parts never left the building, and when Tesla sent representatives to retrieve its equipment, accompanied by law enforcement, they were turned away. Angstrom allegedly then asked for an extra $250,000 a week to keep operating, which Tesla’s filing described as holding its own property for ransom.
TESLA: U.S. District Judge Christopher R. Wolfe of the U.S. District Court for the Western District of Texas, Waco Division granted Tesla a Temporary Restraining Order and Writ of Replevin in its dispute with Angstrom Automotive (Case No. 6:26-cv-00477).

The restraining order gives Tesla immediate right of entry to Angstrom’s facility to recover the tooling. It is temporary, with a fuller hearing still to come, but the speed of Wednesday’s rebound suggests the Angstrom shortage was indeed the main bottleneck limiting Cybertruck output. Outbound lot counts are an imperfect measure of actual production, since finished trucks can sit for days before shipping, but a lot that full after a lean stretch is a meaningful signal.
Cybertruck output at Giga Texas has fluctuated all year as Tesla worked through supply issues and introduced new trims, including a cheaper Dual Motor AWD version that drew strong early demand.
Venture capitalist Chamath Palihapitiya has cautioned investors shorting SpaceX shares, drawing a direct parallel to the intense short-selling pressure Tesla faced in its early public years.
Responding to reports of elevated short interest in the newly public rocket, satellite, and AI company, Palihapitiya noted that similar dynamics played out with Tesla, where aggressive short sellers ultimately “went broke.”
SpaceX (NASDAQ: SPCX) went public on June 12, 2026, in the largest IPO on record, pricing at $135 per share. Shares quickly surged to an all-time high of $225.64 just days later, briefly implying a valuation exceeding $2 trillion. The stock has since retreated sharply amid valuation concerns, lockup expiration fears, and broader market dynamics.
By early August, it traded near $108–$125, representing a roughly 50 percent decline from the peak and bringing the market capitalization closer to the $1.5–1.7 trillion range. On August 4, shares closed up more than 9 percent at $125.33 ahead of earnings before facing pressure in after-hours and premarket trading.
Short interest has climbed dramatically. According to S3 Partners data widely cited in market reports, short positions reached approximately 219.3 million shares by late July, about 34 percent of the limited public float of roughly 640 million shares, and represented a notional value of around $24.6 billion.
Utilization of shares available to borrow hit 95 percent, with borrow fees rising. This level of shorting exceeded the dollar value of short bets against Tesla at the time and built rapidly ahead of two catalysts: the company’s first post-IPO earnings and an August 6 lockup expiration that could free up to 911.5 million additional shares.

CEO Elon Musk has issued warnings of his own. In mid-July, as short interest approached one-third of the float, he posted that “the survival probability of firms who maintain a significant short position in SpaceX over time is very low,” reiterating his view that the company could ultimately be worth more than Earth if it achieves its goals.
On August 4, just before earnings, Musk responded to the latest short-interest data by saying, “I try to warn them, but they just double down.”
SpaceX delivered its first quarterly results as a public company after the close on August 4. Second-quarter revenue rose 92 percent year-over-year to $7.8 billion, beating consensus estimates near $6.8–6.9 billion.
The net loss narrowed to $541 million, or 9 cents per share, better than the roughly 23–24 cent loss expected. Starlink/connectivity contributed about $4.3 billion (up 66 percent), while the AI business generated $2.6 billion (up roughly 250 percent). Capital expenditures were heavy at $18.4 billion, largely tied to AI infrastructure. Management projected a $100 billion annualized revenue run rate by year-end 2026 and outlined a path toward $1 trillion in annual revenue by 2030.
The combination of Chamath’s historical reminder, Musk’s repeated alerts, and the company’s ambitious growth targets underscores the high-stakes debate surrounding SPCX. Short sellers are positioned for near-term supply pressure from the lockup, while long-term bulls point to Starlink scale, Starship progress, and AI compute expansion as reasons the bears may ultimately face the same fate as many early Tesla skeptics.
