Tesla (TSLA) loses place as US’ most shorted stock amid continued Model 3 push
Tesla (NASDAQ:TSLA) recently lost its place as the most shorted company in the US stock market. With short interest slightly declining this third quarter, Tesla has handed over the title of most-shorted publicly-traded company to Amazon, which currently has a $9.97 billion short interest.
The update on Tesla’s shorted shares was posted on Twitter by Ihor Dusaniwsky, Managing Director of Predictive Analytics at S3 Partners LLC, a financial analytics firm based in New York. Dusaniwsky noted in his update that Tesla short interest currently stands at $9.83 billion, which translates to around 32.43 million shares shorted, or 25.43% of the company’s float. The S3 Partners executive further noted that Tesla shorts are up $638 million this week amidst TSLA’s -6.02% price move.
Dusaniwsky also noted to Reuters that there was some short covering during the aftermath of Elon Musk’s fateful “funding secured” tweet last August 7. Despite this, most of the shorts that covered their positions then appear to have been replaced by new short-sellers.
“While there was some short covering the week after the tweet, there has still not been any significant net Tesla short covering on the Street. Any traders who have closed down their positions to realize some profits have been replaced by new ones looking for continued price weakness,” he said.
August has proven to be a challenging month for Tesla investors, who saw the company’s shares exhibit even more volatility than usual in the days and weeks following Musk’s announcement and eventual cancellation of his go-private effort. Amidst reported SEC investigations, lawsuits, and increased attacks from critics and short-sellers, Tesla stock has remained resilient nonetheless, staying in the ~$300 range despite dipping as low as $288.20 on August 20.
The S3 Partners executive believes that the resilience of TSLA stock might become a trigger for increased short-selling activity against the electric car maker. Thus, it would not be surprising if Tesla ends up reclaiming its spot as the most-shorted publicly-traded US stock in the near future.
“A $300 Tesla price may be a signal of increased short selling since when Tesla’s stock price dipped below $300 per share in March, shares shorted climbed from 30.0 million to 41.6 million in just over two months,” he said.
Tesla is a polarizing company, attracting an equal number of supporters and critics, and this is particularly evident in the company’s stock. Back in May, there were 39 million TSLA shares held short — the highest in Tesla’s history. That said, the number of shares held short has since exhibited a slight yet seemingly steady decline, dropping to 32.72 million on August 15 and 32.43 million as of this week.
While Tesla continues to deal with the aftermath of Elon Musk’s privatization attempt, the progress of the company’s Model 3 production push is quite encouraging. Over the past two months, Tesla has showed signs that it is capable of maintaining a sustained optimum rate for the production of the electric car — a feat confirmed by Elon Musk in the Q2 2018 earnings call when he announced that Model 3 production hit 5,000 vehicles per week during “multiple weeks” in July. Tesla’s VIN registrations also went into overdrive in August, passing the 100,000-vehicle mark. Baird analyst Ben Kallo referenced the Model 3 in a recent note as well, stating that Tesla’s fundamentals, such as its progress in its mass-production efforts for the electric sedan, is still “underappreciated.”
As of writing, Tesla shares are trading down 0.73% at $300.93 per share.

OpenAI cites distrust of SpaceX in decision to drop Cursor partnership
OpenAI will cut SpaceX-owned Cursor’s model access in November, citing Musk’s history of broken contracts.
OpenAI, the company behind ChatGPT, announced late Friday that it is ending its partnership with Cursor, cutting off the coding tool’s access to its models on November 12. The move comes two weeks after SpaceX completed its $60 billion acquisition of Cursor’s parent company, Anysphere, folding the popular AI coding assistant into Elon Musk’s growing SpaceXAI division.
In a post on its website, OpenAI said the decision came down to trust, not technology. “We cannot be confident that SpaceX will use our technology within our terms of service, based on our experience with Elon Musk’s companies violating contracts,” the company wrote. OpenAI pointed to two specific incidents: X, now part of SpaceX, allegedly breaking the terms of an existing OpenAI contract after Musk bought Twitter.
That lawsuit is the backdrop for all of this. Musk cofounded OpenAI in 2015, left the board in 2018, and sued Sam Altman and Greg Brockman in 2024, arguing they abandoned the company’s nonprofit mission for profit. A federal jury sided with OpenAI in May, finding Musk waited too long to sue rather than ruling on the merits of his claims. Musk said at the time he would appeal to the Ninth Circuit, calling the outcome a “calendar technicality” rather than a real judgment.
SpaceX’s interest in Cursor predates that verdict by weeks. The company first struck a deal with Cursor in April, securing an option to acquire it for $60 billion or pay $10 billion for joint development work instead. As Teslarati reported at the time, the logic was straightforward: Cursor was paying retail prices to Anthropic and OpenAI, two of its most direct competitors, every time a developer used its product, while SpaceX had idle capacity on its Colossus supercomputer, roughly the equivalent of a million Nvidia H100 GPUs, that Cursor could use to train its own models instead. SpaceX exercised the option in June, days after its own IPO, and the deal closed in mid-August.
Once it closed, Musk moved fast. On an all-hands call with more than 1,000 Cursor employees, he reportedly told staff that SpaceXAI’s Grok was playing catchup in the AI race, unlike Tesla and SpaceX in their own markets, and singled out Anthropic as the company to catch. Cursor CEO Michael Truell now reports directly to Musk inside SpaceXAI.
Losing OpenAI’s models leaves Cursor leaning harder on Anthropic’s Claude, which has its own compute agreement with SpaceX, and on Cursor’s in-house Composer model, the one SpaceX’s compute was supposed to accelerate in the first place. OpenAI framed the November deadline as maximum notice under its contract, and said it wants to “go above and beyond” to help developers through the transition. Whether Anthropic makes the same call is now the open question in AI coding.

Tesla Robotaxi gets a massive upgrade in Nevada
Nevada regulators just approved a massive expansion of Tesla’s robotaxi fleet across the entire county.
Tesla’s robotaxi footprint in Nevada just grew by roughly 500 times in a single regulatory vote.
The Nevada Transportation Authority approved Tesla’s full Autonomous Vehicle Network Company permit on Thursday, clearing the way for the company to deploy up to 5,000 driverless vehicles across Clark County over the next 12 months. The decision came during a four hour general session meeting that Tesla investor Sawyer Merritt watched live and reported on X, noting the vote replaces the interim order that had limited Tesla to just 10 robotaxis on a narrow stretch of the Las Vegas Strip.

That earlier cap, covered here after it surfaced on August 13, came with restrictions that looked stricter than what Tesla runs in Austin: a 45 mph speed ceiling, no airport pickups, and a geofence confined to the Strip corridor. The new approval extends Tesla’s operating authority to all of Clark County, with room to request an even wider geofence across the state.
Tesla representatives at the meeting said they have no intention of putting 5,000 cars on the road right away. Commercial rides are expected to start within 30 days, pending vehicle inspections, insurance filings, and fare approval, the standard steps every robotaxi operator in Nevada has had to clear.
Tesla’s own Robotaxi account replied to the news with a short line, The golden future is upon us.
The timing lines up with Tesla’s broader robotaxi push this month. The company is preparing to open Cybercab rides to the public in Austin as soon as this month, and it opened a sweepstakes for riders to win a seat at the launch event. Tesla filed its original application for a 5,000 vehicle Nevada fleet back in June, a request regulators trimmed to 10 vehicles when they issued the interim order in July. Thursday’s vote effectively grants the number Tesla asked for from the start.
Zoox, the Amazon owned robotaxi operator, has run in Nevada since 2025 and was capped at 100 vehicles before Thursday’s decision. Tesla’s new ceiling puts it well ahead of that comparison on paper, though the company has said its actual fleet size will depend on how quickly FSD v15 rolls out, the software update executives have called the gateway to scaling unsupervised robotaxi operations nationwide.

SpaceX’s next trillion dollar bet has nothing to do with rockets, Musk tells staff
Elon Musk told SpaceX staff AI revenue will soon dwarf rockets and Starlink combined entirely.
Elon Musk told SpaceX employees this week that artificial intelligence, not rockets, will soon carry the company’s revenue. In a roughly 29 minute internal address posted on SpaceX’s X account on Tuesday, Musk said AI revenue will pass every other line of business at SpaceX “probably in September” and pull further ahead by the fourth quarter.
The numbers he gave are specific. SpaceX currently runs 1.4 gigawatts of AI compute capacity. Musk wants that at 10 gigawatts by the end of 2027, a jump he tied directly to revenue: “if we bring 10GW of AI online by the end of next year, it will be $300 billion to $500 billion a year in revenue.” He called those “big numbers,” which undersells a projection larger than what most countries produce in a year.

Musk went further on where AI fits into SpaceX’s future. “Probably in four or five years, AI will be 99% of the value of SpaceX,” he told staff, adding that digital intelligence would eventually run “a trillion times” ahead of biological intelligence as computing scales. He tied that growth to the company’s founding mission, telling employees “we must win on AI, because the future is overwhelmingly AI and robots,” with the payoff meant to help fund Starship and a Mars program that increasingly runs through Terafab, the joint Tesla, SpaceX and xAI chip plant.

None of this is entirely new territory. SpaceX told investors much the same story during its first earnings call as a public company on August 4, where Musk moved the company’s $1 trillion revenue target up a year to 2030 and said Starlink could someday carry a majority of the world’s internet. What the all hands video adds is a hard deadline and a specific power figure Musk had not given publicly before, along with a franker pitch to his own workforce that AI, not launch cadence, is now the thing SpaceX is betting its future on.
The AI revenue itself is not coming from SpaceX training its own models. It is largely Starlink acting as the network layer for xAI’s workloads, plus SpaceX renting out compute capacity directly, the same approach behind the roughly $16 billion the company spent on AI infrastructure in a single quarter.
Musk closed the video with a pitch aimed at recruiting and retention rather than investors, telling employees that anyone who helps SpaceX win the AI race will eventually get the chance to go to the moon or Mars themselves. Whether SpaceX can turn 1.4 gigawatts into 10 in seventeen months is the more immediate question, and one that will show up in quarterly numbers well before anyone leaves Earth.
