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.”

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.
We made rockets reusable and are rebuilding the internet in space. The next challenge: making life multiplanetary and understanding the true nature of the universe

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.
