Tesla’s Elon Musk pens open invite to TSLA short with surprise gift offering

Published

on

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.

SpaceX’s newest Starmind will make earth data centers obsolete

Elon Musk confirmed Starmind as SpaceX’s AI satellite constellation name, targeting one million orbital compute nodes.

Published

Elon Musk confirmed that Starmind will be the official name of SpaceX’s planned AI satellite constellation, following a trademark filing by xAI that surfaced earlier this week. Starmind is what’s being described to the FCC as a constellation of up to one million AI satellites

It’s worth noting that SpaceX’s Starlink communication satellite and Starmind are built on the same orbital infrastructure concept but serve entirely different purposes. Starlink is a connectivity network, with satellites receiving and relaying data between points on Earth, and functioning as a high-speed internet backbone in space. The satellites themselves do not process or think, and move information from one place to another, the same function a fiber cable performs underground.

SpaceX just forced Verizon, AT&T and T-Mobile to team up for the first time in history

Starmind, on the other hand, is something completely different, and tather than moving data, its satellites would compute data through artificial intelligence and directly in orbit using onboard processors powered by large solar arrays. Where a Starlink satellite is essentially a very fast pipe, a Starmind satellite is a server. The practical implication is that Starmind would allow AI models to run inference, process queries, and generate outputs from space, then beam results down to users anywhere on Earth within milliseconds, and without the data ever needing to travel to a terrestrial data center.

Starship will be able to carry 30 to 50 AI1 satellites per launch, delivering the equivalent of dozens of server racks per flight, with no land acquisition, no power grid approval, and no cooling infrastructure required on the ground.

SpaceX is pursuing this new technology as terrestrial data centers are running into hard limits such as lack of physical space, community opposition, and power and water consumption at a scale that is increasingly difficult to permit. Space has unlimited solar power, natural vacuum cooling, and no zoning boards. Musk said in a June 8 video presentation that he expects space to become the lowest-cost location to deploy AI compute within two to three years. Two AI1 prototypes are scheduled to launch in early 2027, with volume production targeted for the end of that year at a new facility called Gigasat.

The real world applications Starmind enables extend well beyond powering Grok. A constellation of orbiting AI processors could run inference workloads for any paying customer, anywhere on Earth, with latency measured in milliseconds rather than the seconds associated with ground-based cloud routing across continents. Starmind, if it scales as described, would make SpaceX the landlord of AI compute the same way Starlink made it the landlord of satellite internet.

SpaceX makes $20 billion move to optimize its balance sheet

Published

Credit: SpaceX

SpaceX announced today that it commenced its first-ever public bond offering, marking a significant step in the newly public company’s capital markets strategy.

The company announced an offering of senior unsecured notes expected to raise at least $20 billion.

The move comes just a short time after SpaceX completed one of the largest initial public offerings in history. In mid-June, the company priced shares at $135 and raised more than $85 billion, propelling founder Elon Musk’s net worth past the trillion-dollar mark and giving the firm substantial liquidity.

According to the company’s SEC filing, the net proceeds from the notes will be used primarily to repay in full the outstanding borrowings under its existing bridge loan facility, cover related fees and expenses, and fund general corporate purposes. The offering is being conducted under Rule 144A, as well as Regulation S, targeting qualified institutional buyers and non-U.S. investors. Notes will be unsecured obligations ranking equally with other unsubordinated debt.

The $20 billion bridge loan was used to refinance approximately $17.5 billion in higher-cost “junk” debt tied to X and xAI. SpaceX had merged with xAI in February 2026 in an all-stock deal. The bridge facility, which matures in September 2027, had represented the bulk of SpaceX’s long-term debt.

SpaceX officially acquires xAI, merging rockets with AI expertise

In connection with the bond launch, SpaceX disclosed it held approximately $100.8 billion in cash and cash equivalents as of June 19. Investor calls began on the announcement date, with pricing and launch expected shortly thereafter. Rating agencies have assigned investment-grade ratings to the proposed bonds, reflecting confidence in SpaceX’s dominant position in commercial launches and the growth trajectory of its Starlink internet offering.

The debt raise also allows SpaceX to optimize its balance sheet by replacing short-term, higher-cost bridge financing with longer-date, lower-cost fixed-income securities. This provides greater financial flexibility to support capital-intensive initiatives, including the development of Starship, the expansion of the Starlink constellation, and the integration of AI capabilities following the xAI combination.

SpaceX shares (NASDAQ: SPCX) fell sharply on the news, dropping over 16 percent overall on the market on Monday. The stock had surged initially after debuting but pulled back amid profit-taking and broader market dynamics.

Overall, the bond offering underscores SpaceX’s transition to a mature public company with access to diverse funding sources. It positions the firm to pursue its long-term vision of multiplanetary expansion and AI infrastructure, while maintaining a disciplined approach to its capital structure in a high-growth but capital-heavy industry.

SpaceX is launching a secret spacecraft that could change how things are made in space

SpaceX’s secret disk-shaped Starfall capsule is targeting a market no reentry vehicle has cracked.

Published

on

By

SpaceX is targeting Tuesday, June 23 for the first flight of Starfall, a reentry capsule the company has developed almost entirely in private. The Falcon 9 launch window opens at 6:43 a.m. ET from Space Launch Complex 40 at Cape Canaveral Space Force Station, with a backup window available the same time on June 24. SpaceX has made no public announcement about the vehicle, only providing launch details. Everything known about it has come through FAA and FCC regulatory filings.

What makes Starfall different starts with its shape. Rather than the traditional cone used by Dragon and every other cargo return capsule in operation, Starfall is a flat disk that measures roughly  10.2 feet (3.1 meters) wide and just 2.5 feet (0.75 meters) tall, and weighing 4,630 pounds (2,100 kg) and capable of returning up to 2,200 pounds (1,000 kilograms) of payload from orbit. The disk geometry maximizes structural efficiency and payload volume relative to mass, and the heat shield mechanically jettisons just before splashdown, allowing recovery teams to retrieve both the capsule and the shield separately from the Pacific Ocean.

The difference with Starfall from existing competitors, such as Varda Space Industries, which has largely built the orbital manufacturing market and returns heavy payloads per flight is that Starfall’s specification is roughly 30 times more per mission, and is designed to be mass-produced and launched on either Falcon 9 or Starship. That combination of volume and launch access is something no standalone startup can replicate, and it puts SpaceX in direct competition with the companies that currently pay it to reach orbit.

SpaceX to launch military missile tracking satellites through new Space Force contract

The intended market is orbital manufacturing: pharmaceuticals, protein crystals, semiconductors, and advanced optical fiber that physically cannot be produced in the presence of gravity. FAA documents describe Starfall’s long-term purpose as building a “self-sustaining commercial in-space manufacturing market” and as a potential successor to the industrial capabilities of the International Space Station, which is set to retire in the late 2020s. Military rapid global cargo delivery is a parallel application under active discussion with the Pentagon.

The reason some industries seek manufacturing in space comes down to gravity. On Earth, gravity causes materials to settle, separate, and deform during production. In microgravity, those constraints disappear.

SpaceX’s already controls launch access, which means it currently functions as the landlord for every competitor in the orbital manufacturing return space. Starfall converts that landlord position into vertical ownership, and it would no longer just carry other companies’ capsules to orbit, but rather operate the capsule, own the return logistics, and capture the service revenue directly. Viewed alongside Starlink, Colossus, and the xAI merger, Starfall fits a consistent pattern: SpaceX identifying infrastructure layers that others depend on and moving to own them outright. Orbital manufacturing return is the next layer on that list.

If Tuesday’s reentry, parachute sequence, and recovery demonstration goes as planned, the second FAA-approved test flight follows. A successful pair of demos would position SpaceX to begin offering Starfall as a commercial service, likely first to pharmaceutical and materials science customers before scaling toward the military and broader manufacturing segments.
