The epic battle between Elon Musk and the Tesla haters
In a fascinating article in Institutional Investor, Michelle Celarier writes that Tesla [NASDAQ: TSLA] is: “the biggest short in the U.S. market; about 27 percent of Tesla’s free float is short, for a value as high as $10 billion” according to S3 Analytics, a firm that tracks short sales. That said, “the stock has soared more than 1,300 percent since Tesla went public in 2010. It is the first automaker to go public since Ford in 1956, making it one of the darlings of the post-financial-crash bull market.”

It turns out that one of the most notorious Tesla shorts is Mark Spiegel. And Spiegel hasn’t even driven a Tesla yet. He says, “I’m more into sports cars.” According to Celarier, “Spiegel has become something of a zealot on Tesla. His small hedge fund, Stanphyl Capital Management, runs a mere $8.5 million, given that it was down 20 percent this year through August. That’s largely due to his short of Tesla, which had gained 74 percent this year, making it the worst-performing short of the year.”
However, there are bigger players out there shorting Tesla. Celarier reports that: “Everyone who’s anyone in Wall Street’s small and clubby world of short sellers has been short Tesla at one point or another… In the past, some of them also shorted Google and Amazon — other high flyers who weren’t making a profit — and somewhat sheepishly [now] admit they were wrong. Clearly, these guys are not dreamers from California’s La La Land, and Musk’s grand plans and his ‘save the world’ ethos can elicit a few eye rolls.”
Another well-known Tesla short, James Chanos of Kynikos Associates, “has been railing against Tesla for at least two years on CNBC and at numerous conferences. He has gone so far as to call Tesla a cult.” Speaking of Tesla’s CEO Elon Musk, Chanos proclaims, “People want to believe he’s some sort of visionary… In a milieu of boring people, they think he is changing the world. He’s not boring. He’s somebody they can attach their hopes and dreams to.”

So why does Tesla attract so many arguments on Wall Street? On the one hand, “Looking at its balance sheet, Tesla is [considered] the perfect short. But its pioneering status in an industry facing wrenching technological upheaval, and its charismatic CEO, has won it legions of admirers and turned it into a battleground stock. Sure, Tesla’s lofty stock price makes it a risky buy — but also a perilous short.”
Anger and hope permeate both camps of investors. “Short sellers berate Tesla investors as momentum chasers, tree-huggers, or simply Elon Musk groupies, but these investors have bought into a vision that has already made great leaps toward building a sustainable energy ecosystem — a costly endeavor that has no shortage of well-heeled enemies.”
And while an army of short sellers persist, plenty of Wall Street’s power players remain steadfast Tesla longs: “The biggest holders, aside from Musk, are mutual funds like Fidelity Investments, which has owned the stock since the IPO. With a current 12.8 percent stake (down from a high of 15 percent), the mutual fund giant is the largest institutional investor in Tesla, and portfolio manager Kyle Weaver says Fidelity has a long-term perspective on the company that is playing out largely as expected.”

“It was the worst short I’ve ever had,” says Whitney Tilson, managing partner of Kase Capital Management, who was short when the stock went from $35 to $205. Last month, Tilson told investors he’s shutting down his funds due to poor performance. Tilson explains, “I can do the numbers and see how much money the company is losing, but you’re short an incredibly maniacally driven CEO, with maniacally driven engineers assaulting the world’s largest industry. If they succeed, Tesla could be a $400 billion market cap company.”“The internal combustion engine is toast long term. It’s game over. The costs of making an internal combustion engine do not go down, while the cost of battery technology has gone down every year,” says Fidelity’s Weaver. “The secular trends that will drive Tesla’s fundamentals are a decades-long trend.” He also applauds Tesla’s environmental mission, “I don’t want to bet against that in an emotional sense.”
Musk is also not afraid to openly attack Wall Street’s short sellers. Let’s not forget, “Musk, who has talked about being bullied as a child, seems to delight in taunting his tormentors. In 2013 he gloated on Twitter, ‘Seems to be some stormy weather over in Shortville these days,’” and once cautioned short sellers that a “tsunami of hurt” was coming in a televised interview.
Celarier writes, “To be sure, a mania surrounds Tesla… [and] betting against Musk is a tough proposition. Tesla has already survived near-bankruptcy events, and Musk has plenty of friends in tech companies with much higher valuations, like Larry Page at Google, that could afford to partner with Tesla or take it over. (Google had struck a handshake deal to buy Tesla during a near-death moment in 2013, according to Vance’s biography.)”
There’s also massive opportunity for Tesla in China: “Earlier this year, China’s Tencent Holdings took a 5 percent stake in Tesla. China is proposing to mandate a zero-emissions standard in 12 percent of new cars by 2020 and is considering letting wholly owned foreign electric-car companies operate there. The Chinese market is expected to be huge, and Tesla is charging ahead there. It is already building a new supercharger network in the country and plans to both build and sell cars there.”
Such realities make shorting Tesla, for all its financial shortcomings, a difficult call. As Tilson puts it, “I don’t want to be short open-ended situations. The tail risk is just too high.”

Tesla Cybercabs narrowly miss deadly Amazon cargo plane crash
An Amazon cargo plane crash near Miami’s airport stopped feet from dozens of Tesla Cybercabs.
An Amazon Prime Air Boeing 767 cargo jet overran the runway at Miami International Airport on Sunday afternoon, killing five people and injuring five more. The jet, operated by North Carolina based carrier 21 Air as Flight 7598, touched down around 2 p.m. after arriving from San Juan, Puerto Rico, then crossed the airport perimeter, plowed across NW 67th Avenue and struck multiple vehicles before catching fire, according to the Associated Press.
Photos and video from the scene show the aircraft’s nose stopped within meters of a fenced staging lot holding dozens of gold painted Tesla Cybercabs, the steering wheel free robotaxi Tesla began putting on public roads in Austin last week. Miami-Dade Fire Rescue has confirmed the plane struck “multiple vehicles” but has not said whether any Cybercabs were among them, and neither Tesla nor airport officials have addressed the fleet directly.
The Cybercabs had not yet entered commercial service in Miami. Tesla’s existing Robotaxi operation there runs on modified Model Y vehicles and has been unsupervised since Ashok Elluswamy confirmed the detail on X in July.

Elon Musk offered the briefest of reactions. Replying to a Zero Hedge post about the Cybercabs sitting so close to the wreckage, he wrote a single word: “Weird.” He has not commented further, and Tesla has not issued a statement.
The timing puts Tesla’s newest vehicle near an unrelated but highly visible tragedy just days after its Austin debut, a launch that had already drawn scrutiny from federal regulators. The National Highway Traffic Safety Administration opened an audit how Tesla certified the Cybercab as compliant with federal vehicle safety standards, a process Teslarati covered after the vehicle’s September 3 launch event. That inquiry concerns the car’s lack of a steering wheel and pedals, not the Miami crash.
Investigators from the FAA and NTSB are focused on the plane, not the parking lot beside it. Flight data reviewed by outlets including Simple Flying show the 767 touched down around 170 knots, well above the 135 to 140 knot range typical for the aircraft, though investigators have not determined a cause. Amazon said it is working with authorities and that its priority is the safety of everyone affected.
Whether any Cybercabs were damaged, and what Tesla plans for the fleet parked near one of the country’s busiest airports, remain open questions.

Tesla Cybercab is coming to Asia this month as US service officially begins
Tesla Asia says Cybercab will be on display in Hong Kong, Tokyo, Beijing and Shanghai this month.
Tesla’s Cybercab is heading to Asia. The official Tesla Asia account posted on X Thursday, inviting Cybercab fans to “Come experience the future of autonomy in Hong Kong, Tokyo, Beijing & Shanghai.” The post went up within hours of Tesla’s own Cybercab milestone in Texas, where the company said Thursday it had begun offering rides in across Austin.
Exact dates and venues for the Asia tour haven’t been released yet, though Tesla Hong Kong replied to the announcement with “Cybercab will be on display in Hong Kong soon,” while Tesla Japan’s response pointed fans to a sign up page for updates. Neither post mentions test rides or a service area, and nothing so far suggests Tesla is launching Robotaxi operations in any of the four cities. Based on how Tesla has run past Cybercab tours, in Europe in late 2024 and at US shopping centers that same December, the Asia stops are almost certainly static displays at Tesla stores or public venues as a means to stimulate buzz for its future driverless ride-hailing service in the big cities.

The timing lines up with Tesla’s only prior Cybercab appearance in the region, a booth at the China International Import Expo in Shanghai last November, which Teslarati covered at the time. At that event, Tesla’s regional general manager for Shanghai framed the car as evidence of the company’s broader mission, a message Tesla has since formalized in its Master Plan Part IV, which states that “autonomous vehicles have the capacity to dramatically improve the affordability, availability and safety of transportation while reducing pollution, particularly in our increasingly dense global cities.” The same document is where Tesla lays out its “sustainable abundance” framing for Cybercab and Optimus alike, describing the two as the hardware behind an AI driven push to cut the cost of transportation and labor at scale.
Whether Cybercab actually operates as a robotaxi anywhere in Asia remains an open question, considering China has already pushed an autonomous ride-hailing market that’s run on homegrown players like Baidu’s Apollo Go and Pony AI. For now, the four city tour reads as a marketing push timed to Austin’s momentum.

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.
