Neuralink has responded to claims of inhumane treatment during the animal testing phases of various company products, stating that animal welfare is a priority. “At Neuralink, we are absolutely committed to working with animals in the most humane and ethical way possible.”
Last week, reports surfaced of a lawsuit against the University of California at Davis from the Physicians Committee of Responsible Medicine (PCRM). The suit claims that the facility “failed to provide dying monkeys with adequate veterinary care, used an unapproved substance known as “Bioglue” that killed monkeys by destroying portions of their brains, and failed to provide for the psychological well-being of monkeys assigned to the experiment.” Earlier today, Teslarati reported an extensive timeline of events from the beginning of the partnership between UC Davis and Neuralink to the most recent developments, which include the potential of videos and photographs of the animals involved in the testing. Teslarati obtained several copies of veterinarian records from autopsies of some monkeys used in the experiments.
Neuralink is now responding to the various claims of animal abuse in a lengthy statement that outlines the past, present, and future developments of Neuralink trials. The company maintains that all animals are treated respectfully and ethically.
EXCLUSIVE: Neuralink dragged into humane testing lawsuit – Timeline of Events
Neuralink ended its partnership with UC Davis in November 2020, just two months after PCRM sent a California Public Records request for information regarding the Neuralink trials. The request is eventually denied in accordance with California State Code 6255(a), which says that the Agency “shall justify withholding any record by demonstrating that the record in question is exempt under express provisions of this chapter or that on the facts of the particular case the public interest served by not disclosing the record clearly outweighs the public interest served by disclosure of the record.”
Neuralink took several of the monkeys back to its testing facilities in Northern California for in-house experiments. “Once construction of our in-house facility was completed, we were able to bring some unimplanted macaques from UC Davis with us to Neuralink. This included Pager, who would later be implanted with our Neuralink device and go on to achieve outstanding brain-computer interface performance, while freely behaving and unrestrained, as demonstrated in the Monkey MindPong video,” the company’s official response said. “While the facilities and care at UC Davis did and continue to meet federally mandated standards, we absolutely wanted to improve upon these standards as we transitioned animals to our in-house facilities.”
Neuralink says that “no injuries occurred at any time to animals housed at UC Davis” while the tests were ongoing. The company admits several animals were euthanized for research purposes, but they were done under controlled circumstances:
-
“The initial work from these procedures allowed us to develop our novel surgical and robot procedures, establishing safer protocols for subsequent survival surgeries. Survival studies then allowed us to test the function of different generations of implanted devices as we refined them towards human use. The use of every animal was extensively planned and considered to balance scientific discovery with the ethical use of animals. As part of this work, two animals were euthanized at planned end dates to gather important histological data, and six animals were euthanized at the medical advice of the veterinary staff at UC Davis. These reasons included one surgical complication involving the use of the FDA-approved product (BioGlue), one device failure, and four suspected device-associated infections, a risk inherent with any percutaneous medical device. In response we developed new surgical protocols and a fully implanted device design for future surgeries.”
Interestingly, PCRM said in a press release that “BioGlue” is an unapproved substance. FDA documents obtained by Teslarati show that BioGlue was approved for use in 2001, but the agency also included a warning of potential side effects when BioGlue is applied to the phrenic nerve. Application of BioGlue to this area in animals can cause acute nerve injury. Additionally, “BioGlue application to the surface of the heart can cause coagulation necrosis that extends into the myocardium, which could reach underlying conduction tissue and may cause acute, focal sinoatrial node degeneration,” the documents said. Five pigs were tested during initial animal experimentation while the FDA was determining BioGlue’s safety. All five pigs survived to the designated observation time.
Neuralink details humane animal treatment during Link v0.9 testing
Presently, the animals involved in Neuralink testing are housed at the company’s 6,000-square-foot facility that houses farm animals and rhesus macaques. The company takes care of the animals from the time they enter the facility to the time they leave, even detailing an animal’s process for “retirement:”
“Can we release the animals that regularly choose not to participate or who have completed their contribution to the study? Yes! We opted to retire animals at the conclusion of their projects. We retired several macaques to a sanctuary last March because they consistently chose to spend their day swimming in their pools, foraging, and relaxing in their hammocks rather than attending the game we presented to them. Their brand new enclosures and sanctuary costs were fully funded by Neuralink.”
Moving forward, Neuralink says it is always working to improve the current standards for animal well-being. “We also look forward to a day where animals are no longer necessary for medical research. Yet our society currently relies on medical breakthroughs to cure diseases, prevent the spread of viruses, and create technology that can change how people are able to interact with the world. However, if animals must be used in research in the meantime, their lives and experiences should be as vital and naturalistic as possible. We will always strive to surpass the industry standard and never stop asking ourselves: “Can we do better for the animals?”, and never forget it is a privilege to work with animals in research. It is our responsibility as caretakers to ensure that their experience is as peaceful and frankly, as joyful as possible.”

SpaceX and Nvidia team up on Musk’s orbital AI bet
SpaceX revealed a new Nvidia satellite partnership, then Musk pledged an exclusive Nvidia hardware commitment.
SpaceX and Nvidia are now working together on the hardware that will power Musk’s orbital data center ambitions. SpaceX announced on X on Tuesday that it is partnering with Nvidia to design the compute payload for Starmind AI1, the first satellite in a planned constellation built to run AI workloads directly in orbit. Each Starmind satellite will carry Nvidia’s Rubin GPUs and Vera CPUs, according to the post, which included renderings of the payload design.
The announcement landed hours before SpaceX’s first earnings call as a public company, where Musk went further, saying the company has committed to building its AI infrastructure exclusively on Nvidia hardware. “We think the Vera Rubin architecture is the best architecture. We think it’s the best AI computer, and we greatly value our close cooperation and partnership on many levels with Nvidia,” Musk told investors on the call,. “So we’re exclusive to Nvidia.”
Musk said SpaceX plans to deploy Nvidia’s Vera Rubin NVL72 rackscale system, codenamed Kyber, both on the ground and in space. He set a target of 2 gigawatts of compute capacity online by the end of this year, scaling to roughly 10 gigawatts by the end of 2027.
SpaceX’s newest Starmind will make earth data centers obsolete
Starmind has been in development since Musk confirmed the name in June, following an xAI trademark filing that tipped off the project before SpaceX made it official. The idea is massive in scope and instead of moving data down to ground based servers, satellites equipped with onboard processors and large solar arrays would compute AI workloads in orbit and beam results back to Earth. SpaceX has already filed with the FCC for a constellation of up to one million satellites to support the effort, citing constant solar power and the absence of zoning restrictions as advantages over terrestrial data centers.
The Nvidia exclusivity marks a shift in tone from just two weeks ago, when Musk was busy knocking down a report that SpaceX had ordered $52 billion worth of Nvidia GPUs through Foxconn, calling it fake news at the time. The dollar figure in that rumor may have been wrong, but the underlying direction seems correct. SpaceX’s AI division already leases Colossus compute capacity to Anthropic and Google, and Tuesday’s earnings report showed AI revenue climbing sharply as those deals ramp up.
Nvidia shares rose roughly 3% in Tuesday trading on the news, while SpaceX stock climbed nearly 9% during the day before giving back gains after hours as investors digested the earnings report’s capital spending figures.

SpaceX (NASDAQ: SPCX) reported a beat in revenues and EBITDA in its first earnings call report while also minimizing losses as its business continues to gain momentum.
After its IPO in July, SpaceX saw some tough losses on Wall Street due to a major selloff after a delay in its 13th Starship test flight. The ship launched later that week and completed what was arguably the most successful IFT operation in the Starship program’s history.
Nevertheless, the company is continuing on and reported some encouraging financials while also promoting what appears to be a robust outlook moving forward in its Space, AI, and Connectivity divisions.
SpaceX to report first-ever earnings today: here’s what to expect
Earnings Results
- Revenues: $7.8 billion reported vs. $6.7 billion expected
- Adjusted EBITDA: $3.5 billion vs. $2 billion expected
- Net loss of $541 million, an improvement of $467 million from net loss of $1.0 billion
Additionally, CFO Bret Johnsen had these comments:
“2026 has been a momentous year so far, and the second quarter demonstrated the true power of SpaceX. Revenue growth accelerated across all our business segments and we delivered strong operating leverage, with significant margin expansion led by our new AI compute agreements. Our unparalleled leadership in launch, Starlink subscriber growth, new enterprise and government partnerships, and best-in-class AI infrastructure underscore our ability to drive meaningful scale and deliver attractive returns. As a newly public company, we are delighted to welcome our broad base of shareholders and bondholders. We ended the second quarter with $100 billion of cash, cash equivalents, and marketable securities, and $47.5 billion in backlog. This financial strength gives us substantial capacity to invest in Starship, Starlink Broadband and Mobile satellites, and our AI platform, while maintaining a disciplined long-term capital allocation framework.”
Space Business Highlights
SpaceX shared some of its biggest Space Business Highlights for Q2:
- Space revenues grew 55% sequentially and 29% year-over-year to $962 million, driven by a higher number of large customer launches and a favorable customer shift compared to the prior year
- Total costs and expenses for the Space segment were up by $389 million year-over-year, as we continued to accelerate R&D investments in our Starship program, which we believe will reduce the cost to orbit by 99% or more relative to the historical average, and unlock significant revenue potential across all business segments
- Leading launch provider for the world with 78 launches and 1,041 metric tons of mass to orbit deployed over the six months ended June 30, 2026, primarily allocated to Connectivity for the deployment of our Starlink constellation
- Starship V3 development continued to advance towards full and rapid reusability:
- Completed Starship V3’s first suborbital mission in May, Flight 12, which achieved a successful lift off from our new Starbase pad, a precision landing of Starship’s upper stage, and deployment of modified V2 Starlink satellites
- Subsequent to the second quarter, completed Starship Flight 13 in July, which achieved all flight objectives including deploying 20 production V3 satellites, demonstrating in-space relight of a Raptor engine, and executing the softest ever splashdown of Starship, providing critical views of an intact heatshield
SpaceX will report its earnings today at 4:30 P.M. EDT.

Elon Musk issued a second pointed warning to SpaceX short sellers on Tuesday, just hours before the company was set to release its first quarterly earnings as a publicly traded firm. Responding to a report highlighting elevated short interest, Musk wrote on X: “I try to warn them, but they just double down …”
The comment came as data from S3 Partners showed roughly 95 percent of available SPCX shares to borrow were on loan, translating to about 34 percent short interest as a percentage of the float. The stock has traded under pressure since its record-breaking IPO in June 2026, declining significantly from early peaks.
I try to warn them, but they just double down … 🤷♂️
— Elon Musk (@elonmusk) August 4, 2026
This marks the second such message from Musk in under three weeks.
On July 17, amid post-IPO volatility, he stated: “The survival probability of firms who maintain a significant short position in SpaceX over time is very low.” At that time, SPCX had fallen roughly 30 percent from its peak above a $2.6 trillion valuation, with short sellers reportedly realizing gains of about $8.7 billion.

Musk’s warning aligned with optimistic analyses projecting that Starship-driven cost reductions could enable a multi-trillion-dollar space economy through applications such as orbital solar power, asteroid mining, data centers, and Mars-related projects, positioning SpaceX as critical infrastructure.
SpaceX is scheduled to report second-quarter results after the market close later today, followed by a webcast. Analysts anticipate revenue near $6.9 billion, reflecting growth in Starlink, launch services, and AI-related segments. The earnings release precedes a major lockup expiration on August 6 that could free hundreds of millions of insider shares.
Musk has a long track record of confronting short sellers, particularly regarding Tesla, where he has argued that persistent bearish positions underestimate transformative technologies. Critics view his optimism as overly ambitious given near-term stock fluctuations, while supporters see temporary dips as opportunities in a longer-term expansion of the space economy.
As SpaceX opens its books to public scrutiny for the first time, the high short interest and Musk’s repeated cautions set the stage for heightened market attention on the results and management’s commentary.
