Tesla (TSLA) short responds to Elon Musk’s invite with odd demands and side remarks
Tesla (NASDAQ:TSLA) short and hedge fund manager David Einhorn has issued a response to Elon Musk’s invitation to meet and visit the electric car maker’s facilities. Einhorn agreed to meet with Musk in his response, though he had a number of odd demands and remarks that went along with his acceptance.
Similar to Musk’s letter, Einhorn’s response was long and posted on Twitter via a screenshot. In it, the Greenlight Capital President challenged the Tesla CEO, claiming that while both his hedge fund and Tesla “struggled” last year, his business has generated “real profits for investors” since it was established in 1996. He also denied that his TSLA short has performed badly as well, arguing that it has merely “fluctuated.”

Dear Elon,
I am glad that you read our October letter and would like to discuss it. You say we “made numerous false allegations against Tesla.”
-
Could you be more specific? Can you point to at least one sentence that is false and refute it with facts? We certainly are capable of making mistakes and if we said anything false, we will correct it for the record. Facts do matter to us. I can’t imagine how it would feel to have entire websites like https://elonmusk.today chronicling your untruths.
Our business have some similarities and differences. We both struggled last year. However, a key difference is that Greenlight’s business has generated real profits for our investors since we began in 1996. Tesla’s business financials reflect a decade of annual losses and an accumulated deficit of $6 billion, despite billions of dollars of taxpayer subsidies.
As for our short of Tesla, it’s fluctuated. In a multi-year bull market, it hasn’t performed badly. By continually changing the narrative and narrowly averting crisis after crisis, you have certainly kept it interesting. We shall see what happens from here.
We welcome your offer to let us learn more about Tesla and will take you up on it. This is a stark contrast from Tesla’s prior position, as your IR team has refused several requests from us to converse directly and answer our questions.
I think facility visits would be fun (can we start in Buffalo?). I might learn the difference between your alien dreadnought factory and cars made by hand in a tent.
The truth is we are much more interested in, and have many questions about, your financial statements. Perhaps, we could spend some time together with your CFO, Zach Kirkhorn.
As an example, my understanding of auto sales is that car buyers don’t typically drive off the lot without paying for the car. Publicly-traded auto dealers have only a couple days of account receivable balances. Yet, Tesla is owed over $1 billion by its customers. With customers paying up front, why are the balances so high? In September 2018, you said the receivables doubled up because the quarter ended on a Sunday. That answer wasn’t very satisfying at the time. This year, the quarter ended on a weekday. Sales are lower than they were a year ago and yet, the receivables were high. We are curious.
-
We have dozens of questions like that.
I truly appreciate your offer to build a direct communication so we can learn more about Tesla. Please advise on how we should go about scheduling. And have a nice weekend.
David Einhorn
Looking at Einhorn’s response, it appears that the TSLA short is not really taking an open-minded approach in responding to Musk’s letter. Instead, Einhorn seems to be doubling down on his allegations of fraud against Musk with his suggestion that the electric car maker’s finances don’t line up. With such a response, including snide, outdated references to GA4, it would not be very surprising if Tesla does not choose to go forward with Elon Musk’s initial invitation.
This is quite ironic considering that Einhorn himself and his fund, Greenlight Capital, were fined by the UK Financial Service Authority (FSA) for £7.2 million (US$9.27 million) for insider trading. According to the FSA, Einhorn engaged in “market abuse” in relation to a fundraising by pub group Punch Taverns in June 2009. Greenlight has also struggled over the past year, being unable to beat the market and declining 34% last year, its worst year since the fund was founded.
Disclosure: I have no ownership in shares of TSLA and have no plans to initiate any positions within 72 hours.

Elon Musk
The real reason Elon Musk wants every car connected to space
Elon Musk says all cars will eventually need Starlink to handle massive AI bandwidth demand.
Elon Musk is making the case that satellite internet, not fiber or cellular towers, will end up wired into every car on the road. In a string of posts on X, the SpaceX CEO wrote that all cars will have Starlink in the future and called satellite connectivity the only way to get super high bandwidth to billions of vehicles.
The posts started with Musk endorsing a Cloudflare forecast that traffic generated by autonomous AI agents will soon dwarf traffic generated by humans browsing the internet, a shift he described as not a close call at all. From there he narrowed the argument to infrastructure, writing that the only system that can support the insanely fast bandwidth growth needed by AI is Starlink, before extending the logic to cars specifically.
AI agentic Internet traffic will obviously VASTLY exceed human usage. Not a close call at all.
Cloudflare’s forecast is accurate. https://t.co/VztgrinN5k pic.twitter.com/Wo4FiRKjPU

The timing lines up with Tesla’s own hardware decisions. On July 20, Tesla confirmed the Cybercab would ship with a Starlink V5 terminal built into its roof, the first time the company had put satellite hardware in a production vehicle. A day later, Tesla’s head of AI, Ashok Elluswamy, explained the connection wasn’t there for safety and that Cybercab’s driving stack runs entirely on onboard cameras and compute, while the satellite link exists for navigation, customer service, and fleet management instead. Musk followed with his own post about the feature, saying riders would be able to watch 4K streaming video during rides.
By July 22, Musk had already said Starlink would extend beyond Cybercab to Tesla’s full lineup. Sunday’s posts push that same logic outward again, this time framed as a requirement across the industry rather than a feature specific to Tesla, and tied directly to the bandwidth AI systems are expected to consume.
SpaceX’s newest Starmind will make earth data centers obsolete

The AI argument has been building on SpaceX’s side for months. The company has an FCC filing pending for a third generation Starlink constellation, and it has separately proposed Starmind, a constellation of up to a million satellites designed to run AI computation directly in orbit rather than just relay data. Musk has said he expects space to become the cheapest place to deploy AI compute within two to three years. Starlink and Starmind serve different jobs inside that vision, one moving data and the other processing it, but Sunday’s posts treat vehicles as one more category of hardware that will eventually need both.
None of this changes anything for Tesla owners today. Cars already on the road keep running on LTE and Wi-Fi, and Tesla hasn’t outlined a retrofit path for existing vehicles. The July 22 commitment applies to future production, not the fleet already delivered. What Musk added on Sunday is the reasoning: satellite connectivity isn’t a Cybercab novelty, it’s a bet that ground based networks won’t keep up with how much data cars, robots, and AI systems are about to generate.
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.

Cybertruck
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.
