Tesla’s Elon Musk pens open invite to TSLA short with surprise gift offering
Following a note to his investors alleging that Elon Musk continues to commit fraud, prominent TSLA short and hedge fund manager David Einhorn has received a response from the Tesla CEO. Musk’s letter, which he shared on Twitter, appears to be a snarky olive branch that offers Einhorn an opportunity to change his mind about the electric car maker.
Einhorn’s Greenlight Capital, which declined by 34% last year partly due to his bet against Tesla, lost its bet against the electric car maker once more in the third quarter. In a letter to his firm’s investors, Einhorn admitted that TSLA was one of its “material losers” of Q3’19 while accusing Elon Musk of “knowingly” orchestrating “significant fraud” with Tesla’s SolarCity buyout in 2016. The TSLA short also accused the electric car maker of failing to warn customers about its burning solar panels and its car battery fires.
Musk, who appears to be adopting a rather confident stance, shared a letter to the hedge fund manager on Twitter. Playfully calling Einhorn by the German translation of his name and dubbing himself as “Treelon Musk,” the Tesla CEO extended a rather snarky olive branch to the short seller. In his letter, Musk invited Einhorn to meet with him and see Tesla’s work firsthand, something that would be wise for the sake of Greenlight Capital’s investors.

Following is Musk’s letter in full.
Dear Mr. Unicorn (fabulous name btw),
We read your Greenlight Capital Q3’19 Investor Letter, in which you make numerous false allegations against Tesla. It is understandable that you wish to save face with your investors, given the losses you suffered from Tesla’s successful third quarter, especially since you’ve had several down years in performance and a sharp drop in assets under management from $15 billion to $5 billion. You have our sympathies.
We also recognize your desire to feel somehow relevant with your Tesla short position at a time when your friends in the Tesla short community have been noticeably recoiling from the public discourse, as the world is increasingly recognizing Tesla’s contributions to science, safety and a sustainable environment.
To the extent that you have any desire to learn about the amazing progress the people of Tesla are making, I would like to extend an open invitation to meet with me to discuss Tesla and tour our facilities. For their sake, I’m certain your investors would appreciate you getting smart on Tesla.
Finally, please allow us to send you a gift of short shorts to help you through this difficult time.
Regards,
Treelon Musk
Musk’s reference to Einhorn and a box of short shorts is based on a series of amusing events last year which began with Einhorn stating that he is not renewing the lease on his Tesla Model S due to tech issues with the car. Responding on Twitter, Musk stated that Tesla will “send Einhorn a box of short shorts to comfort him through this difficult time.” Following Elon Musk’s tweet, apparel maker Chubbies opted to send the hedge fund manager a literal box of shorts, most of which featured a very short 5.5-inch inseam.

Sure enough, Einhorn received his shorts, and he promptly took to Twitter to thank the Tesla CEO for being a “man of his word.” Musk responded by playfully asking Einhorn to put them on and post a selfie, but the TSLA short-seller did not comply. Perhaps this year, things will be different, or maybe Chubbies would be up for the task once more, considering that Kyle Hency, one of the company’s founders, stated that they could keep sending short shorts to TSLA shorts if Elon Musk wishes.

While Einhorn is a Tesla short and he continues to accuse Musk of fraud, among others, he appears to be a bit more level-headed compared to some of the angry, vapid TSLA retail and institutional short-sellers that populate Twitter. Perhaps this is one of the reasons why Musk actually opted to invite Einhorn in what seems to be an attempt to change the hedge fund manager’s mind. Elon Musk’s letter might be rife with snark, but it may, if Einhorn opts to respond, save his fund from more painful losses in the near future.

Tesla Q2 Earnings: Here’s what to expect
Tesla (NASDAQ: TSLA) will report its earnings for the second quarter of 2026 this evening after market close, and investors and analysts are waiting anxiously to see what the company will report for the second three-month span of the year.
Analysts have already put out their expectations from a financial standpoint for the company’s second quarter, but what’s unknown is what Tesla plans to discuss during the call.
Financial Expectations
Wall Street consensus expectations put Tesla’s Earnings Per Share (EPS) at $0.53, while revenues are expected to come in around $26.4 billion.
This would compare to an EPS of $0.39 and $22.19 billion compared to Tesla’s Q2 2025. Last quarter, EPS came in at $0.41 on $22.387 billion of revenue. Additionally in Q1, Tesla beat analyst expectations, but shares dropped over 3 percent the following trading day.
What We Expect
In terms of discussions, Tesla earnings are pretty sporadic and depend on a handful of things, including current events, investor questions, and more.
Tesla uses a platform called Say to field questions from investors and analysts. These questions are what will be used during the call. Here are the top 5 from the Retail side and top 3 from the Institutional side:
Retail:
“Tesla has missed short-term guidance on robotaxi 3 earnings reports in a row, from 50% coverage of USA by end of 2025 to most recently 7 new cities in 1H26. What is keeping Tesla back from accomplishing these short term goals that they’ve set for themselves?”
“What are the main constraints to expanding robotaxi operations faster, and how do you see that lining up with Cybercab production?”
“What’s the current status of Optimus Gen 3 production ramp, initial deployment in factories, and external sales timeline/volume for 2027? What tasks can we expect the Optimus to perform by end of 2027?”
“To reward long-term Tesla retail shareholders for their loyalty, can you commit to achieving at least half of the goals outlined in your 2025 compensation plan before considering any offers to acquire or merge Tesla?”
“Why has growth of robotaxi vehicles stalled? When will we see cybercab start customer rides?”
Institutional
“Previously, you’ve said Tesla would lead the R&D while SpaceX would lead production for Terafab. Can you provide an update on how that division of responsibilities is evolving, and any additional clarity on the expected capital contributions from Tesla and SpaceX?”
“For autonomous driving, Tesla’s fleet created a huge data advantage by collecting billions of real-world miles. That advantage doesn’t yet exist for Optimus. How should we think about data availability and its impact on Optimus development?”
“Why is it necessary to limit robotaxi operations within specific zones within cities to start? Will every city have to be rolled out this way?”
Tesla will report earnings for Q2 this evening with the Shareholder Deck at 4 p.m. ET, with the call starting around 5:30 p.m. ET.

Elon Musk handed Grok something no other AI company can get their hands on
Elon Musk says SpaceX will feed engineering data into Grok’s next model, avoiding restricted material.
Elon Musk said Tuesday that SpaceX will feed its internal engineering data into the next major training run for Grok, the AI model now folded into SpaceX following February’s merger. In a post on X, Musk wrote that SpaceX’s “massive corpus of world-class engineering data,” excluding anything restricted under U.S. arms export law, will be added during supplemental training of what he called the “2T run,” a reference to a roughly two trillion parameter model that would nearly double the parameters behind the latest Grok 4.5 that’s rolling out.
SpaceX’s massive corpus of world-class engineering data (excluding material blocked by ITAR) will be added during supplemental training of the 2T run.
This will dramatically improve Grok’s engineering capabilities. https://t.co/BbQEViFByn
— Elon Musk (@elonmusk) July 21, 2026
The excluded material that Musk is referring to would fall under the International Traffic in Arms Regulations (ITAR), which restricts export of technical data tied to defense and space hardware. That likely rules out propulsion specifics for Merlin and Raptor engines along with guidance and control details for SpaceX’s launch vehicles, but leaves manufacturing knowledge, materials science, and Starlink hardware design on the table.
The announcement extends a pattern that has been building since SpaceX’s Nasdaq debut in June, when the company went public with Grok and xAI’s Colossus supercomputer folded into the pitch to investors.
Days after that listing, SpaceX closed its $60 billion all stock acquisition of coding startup Cursor, giving xAI both enterprise software distribution and a stream of real world developer data to train on. Grok 4.5 launched July 8 running partly on that Cursor training data, with Musk describing it as roughly comparable to Anthropic’s Opus 4.7 but faster and cheaper to run.
Feeding SpaceX’s own engineering data into the next AI model follows the same logic Musk has applied across xAI’s sister companies. Tesla supplies real world driving data and manufacturing expertise, X supplies conversational data, and now SpaceX supplies aerospace engineering data built up since 2002.
Musk did not give a release date for the upcoming AI model, referred to elsewhere as Grok 4.6. He has said the two trillion parameter run is in its final training phase and expected to wrap this week.

Elon Musk sends first warning to SpaceX short sellers
In a pointed message on X, Elon Musk warned that firms maintaining significant short positions in SpaceX over time face “very low” survival probability.
The statement comes amid post-IPO volatility for the rocket company, now trading under the ticker $SPCX.
The survival probability of firms who maintain a significant short position in SpaceX over time is very low
— Elon Musk (@elonmusk) July 17, 2026
Five weeks after what was described as the largest IPO in history, the stock had fallen roughly 30% from its peak above $2.6 trillion, briefly surpassing Microsoft and Amazon in market value. Short sellers celebrated gains of about $8.7 billion, but Musk’s reply underscores his long-term conviction.
The warning directly echoes a detailed bullish analysis arguing that Starship’s cost reductions could unlock a multi-trillion-dollar space economy. Projects ranging from solar power beamed from orbit and asteroid mining to orbital data centers and Mars terraforming were projected to create over $100 trillion in new market capitalization.
In this vision, SpaceX acts as the essential infrastructure provider, akin to AWS for cloud computing, capturing monopoly-like revenues from launches, crew transport, and data traffic across a rapidly expanding frontier.
This is far from the first time Musk has targeted short sellers. With Tesla, he has repeatedly framed persistent bears as destined for major losses. In July 2024, Musk declared that once Tesla achieves full autonomy and volume production of Optimus robots, “anyone still holding a short position will be obliterated. Even Gates,” referencing Microsoft co-founder Bill Gates’ reported short bets.

Earlier, in 2018, he taunted shorts that they had “about three weeks before their short position explodes,” a remark followed by sharp stock gains. Musk has also called short selling “value destroying” and once suggested it “should be illegal,” viewing it as betting against innovation and progress.
Critics often dismiss Musk’s optimism as hype, especially when near-term metrics like quarterly deliveries or stock fluctuations disappoint.
Yet his pattern remains consistent: framing short positions against his companies as fundamentally misjudging exponential technological leaps. For SpaceX shorts, the message is clear: betting against multi-planetary ambitions and the infrastructure monopoly they enable carries existential risk for the firms involved.
As Musk and supporters see it, the space economy’s upside dwarfs Earth-bound valuation models, making today’s dips temporary in a decades-long ascent.
