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.

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.

California snubs Tesla in its newly passed EV incentive that favors Rivian and Lucid
California passed a $135 million EV incentive that rewards Rivian and Lucid while sidelining Tesla
California just drew a line in the EV incentive sand to put Tesla on the wrong side of it. The state recently passed a $135 million program offering first-time electric vehicle buyers a direct incentive with no application required, but the rules were written in a way that leaves Tesla at a structural disadvantage compared to Rivian and Lucid.
The program caps eligible vehicles at $50,000 for new EVs and $25,000 for used ones. That pricing threshold rules out a significant portion of Tesla’s lineup, though some lower-priced Model 3 and Model Y configurations would still qualify. California-based automakers are exempt from the price cap entirely, regardless of what their vehicles cost. Rivian, headquartered in Irvine, and Lucid, based in the San Francisco Bay Area, both benefit from that exemption. Rivian’s R2 starts at roughly $45,000 but has versions above the cap. Lucid’s Air and Gravity start at $70,990 and $79,990 respectively, well above any threshold a non-California company would face.
California hits Tesla Cybercab and Robotaxi driverless cars with new law
Tesla built its reputation and a significant portion of its early market share in California, where EV adoption has consistently led the nation. The company operates its original factory in Fremont, California, and the state was home to Tesla’s headquarters for most of its existence. That changed in 2021 when Tesla moved its corporate headquarters to Austin, Texas. Since then, the relationship between the company and California Governor Gavin Newsom has been openly adversarial, with Musk and Newsom trading public criticism on multiple occasions.
California’s EV incentive landscape has shifted repeatedly in recent years, and Tesla has previously lost eligibility for state-level programs as its vehicles exceeded income-adjusted price thresholds. The federal $7,500 EV tax credit, which Tesla models have qualified for and lost depending on policy cycles, is no longer available after it expired without renewal, making state-level programs more meaningful to buyers than they have been in years.
The practical impact for buyers is more nuanced than the headline suggests. California residents purchasing a Tesla under $50,000 for the first time can still access the incentive. But the exemption written for California-based manufacturers is a structural advantage that rewards where a company plants its headquarters flag rather than where it builds its products, and Tesla moved that flag to Texas.

SpaceX’s newest logo confirms everything about what it’s become
SpaceX officially absorbed xAI under the SpaceXAI brand, completing the largest private merger in history.
SpaceX made its corporate transformation official in May 2026 when Elon Musk posted on X that xAI would cease to exist as a standalone company. “xAI will be dissolved as a separate company, so it will just be SpaceXAI, the AI products from SpaceX,” he wrote.
A new SpaceXAI logo was announced today, visually embedding the xAI letters inside the SpaceX identity, which can be seen as a deliberate design choice that signals the merger is not a partnership but a full absorption and XAi a core function of the same company. The same way Starlink is not a separate brand but a SpaceX product. The announcement closed the loop on a process that began February 2, 2026, when SpaceX acquired xAI in the largest private merger in history, valued at $1.25 trillion. SpaceX at $1 trillion and xAI at $250 billion.
We are now @SpaceXAI. pic.twitter.com/ema66xDWC9

The reason SpaceX bought xAI was stated plainly by Musk at the time of the deal: to build orbital data centers. SpaceX had simultaneously filed with the FCC to launch up to one million satellites designed to function as AI compute nodes in low Earth orbit, escaping what Musk described as the energy constraints limiting AI development on Earth.
xAI provided the AI software stack, with Grok, the X platform, and the Colossus supercomputer infrastructure in Memphis with over 220,000 NVIDIA GPUs, while SpaceX provided the rockets, Starlink, and the capital base to fund it. The two companies needed each other. xAI was burning $2.5 billion in losses on $250 million in revenue. SpaceX was generating an estimated $8 billion in profit on $15 billion in revenue and needed an AI narrative to command the valuation it was targeting for its IPO.
What SpaceX has done, regardless of how the orbital AI vision ultimately plays out, is walk into a public market as something no company has been before: a rocket manufacturer, satellite internet provider, AI software company, social media platform, and supercomputer operator under one ticker. Whether that combination is worth $2 trillion depends entirely on which of those businesses you believe in most.

Tesla challenges startups to score a gig inside its most advanced European factory
Tesla is challenging startups to bring their best battery tech directly to Gigafactory Berlin.
Tesla has issued an open challenge to startups across Europe, inviting them to bring their best battery technology directly to the floor of Gigafactory Berlin. The program, called the JUNI x Tesla Battery Cell Giga Challenge, opened applications this month with a deadline of July 24, 2026, and is targeting startups with solutions that can make battery cell manufacturing faster, cheaper, safer, and more scalable at an industrial level.
The timing of the challenge is directly tied to Tesla’s most aggressive European battery investment yet. On May 12, 2026, Giga Berlin plant manager André Thierig announced a $250 million investment to scale the factory’s annual 4680 cell production capacity from 8 GWh to 18 GWh, more than doubling the previous target set just months earlier in December 2025. Thierig confirmed the expansion on X, saying the investment “will enable 18 GWh of annual 4680 cell production and create more than 1,500 new jobs.” Combined with a previously announced battery investment at the Grunheide site now approaches $1.2 billion.
Today, we announced a $ 250m investment for our Giga Berlin Cell factory. This will enable 18GWh of annual 4680 cell production and create more than 1500 new jobs. Good news during challenging times for the German industry. pic.twitter.com/ou4SWMfWh9

The challenge is looking specifically for startups with proven solutions across five categories: materials, equipment, operations, automation, and artificial intelligence. Applications are screened directly by Tesla’s cell manufacturing team in Grunheide, and the strongest submissions move through technical discussions, a pitch day in front of Tesla stakeholders, and potentially a paid pilot project with the cell team. Tesla is not looking for ideas at concept stage. The program requires applicants to demonstrate working prototypes, test data, or prior pilots before being considered.
The historical context matters here. Elon Musk first announced plans for what he called the world’s largest battery cell production facility alongside the Giga Berlin car factory back in 2020, targeting up to 250 GWh of annual capacity. Those plans were shelved in 2022 when Tesla shifted its battery investment focus to the United States to take advantage of Inflation Reduction Act incentives. The revival of cell production at Giga Berlin, now backed by over $1 billion in committed capital, represents a return to an ambition that was set aside for three years. As Teslarati has reported, the 4680 format is central to Tesla’s long-term cost reduction strategy across vehicles, energy storage, including the Tesla Semi and Cybercab.
By opening the challenge to outside startups, Tesla is acknowledging that reaching 18 GWh at Grunheide will require technology it does not currently have in-house, and it is willing to pay for the right solutions. For a startup in the battery supply chain, a paid pilot with Tesla’s European cell team is as close to a direct commercial path as the industry offers.
