SEC continues to argue for Elon Musk’s “Twitter sitter” deal

A recent letter from the US Securities and Exchange Commission (SEC) states that Tesla lawyers must still pre-approve Elon Musk’s company-related tweets, even though the billionaire won the case centered on his infamous “funding secured” tweet in 2018.

In a letter to the US Court of Appeals for the 2nd Circuit in New York, the SEC argued that Musk’s earlier settlement with the agency is constitutional and valid. Musk’s settlement followed an SEC investigation into the CEO’s “funding secured” claims in 2018. It was also agreed that tweets containing material Tesla-related information would be reviewed by a lawyer — fondly dubbed the CEO’s “Twitter Sitter” by the internet — before Musk posts them. 

Elon Musk’s legal team submitted a brief to a court of appeals in September 2022, seeking relief from what they alleged was a “government-imposed muzzle” that inhibits the CEO’s speech. The appeal came a month after a federal judge denied Musk’s motion to terminate his settlement provision with the SEC.

Earlier this month, a jury found that Elon Musk and Tesla were not liable in a class-action securities fraud trial centered on the CEO’s “funding secured” tweet. Musk’s lawyers then argued earlier this week that the jury verdict should be considered in an appeal against the CEO’s SEC settlement provision.

“In light of the jury finding that Mr. Musk’s tweets did not violate Rule 10b-5, the SEC lacks support both for the consent decree itself and for its arguments on appeal. The verdict provides further reason why the public interest in avoiding unconstitutional settlements easily subsumes the SEC’s purported stake in the consent decree,” Alex Spiro, one of Musk’s lawyers, wrote

The SEC has responded to Musk’s legal team, arguing that the findings of the jury in a private securities-fraud action does not identify a “pertinent and significant” authority. The SEC also argued that Musk is “reading too much” into his jury verdict. 

Following is the SEC’s response. 

“Appellant Elon Musk’s letter notifying this Court about a jury verdict in a private securities-fraud action does not identify a ‘pertinent and significant’ authority. Musk waived his opportunity to test the Commission’s allegations at trial when he voluntarily agreed (twice) to a consent judgment. The district court properly rejected his request to alter the judgment because there were no “significant” changes in factual conditions or the law that justified relief under Rule 60(b)(5). Musk asserts that the consent judgment now “lacks support” given “the jury’s finding,” but this is a non-sequitur; the consent judgment was not conditioned upon the outcome of the private litigation.

“Even if the verdict were somehow relevant, Musk reads too much into it. The Commission had no role in that case. Unlike in a Commission action, the private plaintiff had to prove reliance, loss causation, and damages, In re Tesla , Dkt. 655, at 7-17 (jury instructions), and it is unknown whether the verdict turned on elements that would not burden the Commission at trial, id. , Dkt. 671, at 2-3 (verdict form). Moreover, the court instructed the jury to assume that Musk’s tweets “were untrue,” which confirms the discrete point the Commission was making when it referenced the private action in its brief. Id., Dkt. 655, at 7-8.

“Ultimately, the verdict has no bearing on whether the district court correctly declined to grant the extraordinary remedy of altering Musk’s consent judgment years after entry. The verdict says nothing about the continuing public interest in a negotiated settlement term that does not preclude Musk from tweeting accurately about Tesla or other topics, but rather requires Tesla to review Musk’s Tesla-related communications before publication, including through Musk’s Twitter feed—a communication channel designated by Tesla for disclosure. And the verdict does not justify the inapt application of the ‘unconstitutional conditions’ concept to settlements, even if this Court were to overlook Musk’s forfeiture of any arguments regarding that concept,” the SEC wrote. 

It remains to be seen whether the court will uphold or dismiss the letter submitted by Musk’s legal team. The appeal is expected to be heard in the spring, although an exact date has not yet been scheduled.

Tesla’s golden era is no longer a tagline

Tesla “golden era” teaser video highlights the future of transportation and why car ownership itself may be the next thing to change.

The golden age of autonomous ridesharing is arriving, and Tesla is making sure we can all picture a future that looks like the future. A recent teaser posted to X shows a Cybercab parked outside a home, and with a clear message that your everyday life may soon look like this when the driverless vehicles shows up at your door.

Tesla has begun the rollout of its Robotaxi service across US cities, and the production of its dedicated, fully-autonomous Cybercab vehicle. The first Cybercab rolled off the Giga Texas assembly line on February 17, 2026, with volume production now targeted for this month. Additionally, the Robotaxi service built around it is already running, without human drivers, in US cities.

Tesla Cybercab production ignites with 60 units spotted at Giga Texas

The Cybercab is built without a steering wheel, pedals, or side mirrors, designed from the ground up for unsupervised autonomous operation. Musk described the manufacturing approach as closer to consumer electronics than traditional car production, targeting a cycle time of one unit every ten seconds at full scale.

Drone footage from April 13, 2026 captured over 50 Cybercab units on the Giga Texas campus, with several clustered near the crash testing facility. Musk has noted that Tesla plans to sell the Cybercab to consumers for under $30,000, and owners will be able to add their vehicles to the Tesla robotaxi network when not in personal use, potentially generating income to offset the vehicle’s purchase cost. That model changes the math on vehicle ownership in a meaningful way, making a car something closer to a depreciating asset that can also earn by paying itself off and generate a profit.

During Tesla’s Q4 earnings call, the company confirmed plans to expand the Robotaxi program to seven new cities in the first half of 2026, including Dallas, Houston, Phoenix, Miami, Orlando, Tampa, and Las Vegas. The service already runs without safety drivers in Austin, and public road testing of the Cybercab has expanded to five states, including California, Texas, New York, Illinois, and Massachusetts.

Tesla’s last chance version of the flagship Model X is officially gone

The Signature Edition was no ordinary Model X Plaid. Offered exclusively by invitation to select existing Tesla owners, it represented the final production batch of the current-generation Model X before manufacturing at Fremont ends.

Published

Tesla enabled a last-chance version of its two flagship vehicles, the Model S and Model X, over the past few weeks. The Model X, the company’s original SUV, is officially gone.

Tesla has officially closed the book on its most exclusive send-off for the Model X. The limited-run Model X Signature Edition—priced at $159,420 before fees and limited to just 100 units—is now sold out, with reservations closed as of April 16.

The Signature Edition was no ordinary Model X Plaid. Offered exclusively by invitation to select existing Tesla owners, it represented the final production batch of the current-generation Model X before manufacturing at Fremont ends.

Every unit featured an exclusive Garnet Red exterior paint, unique badging, and a standard six-seat configuration. With full Plaid powertrain specs—Tri-Motor All-Wheel Drive, over 1,000 horsepower, and blistering acceleration—it was positioned as a collector’s item for loyalists who wanted one last shot at owning a piece of Tesla history.

The timing is no coincidence.

Tesla announced earlier this year that it would discontinue regular production of both the Model S and Model X to repurpose the Fremont factory’s dedicated lines for mass production of its Optimus humanoid robots.

Elon Musk has repeatedly emphasized that Optimus could ultimately become more valuable to the company than its vehicle business, with ambitions to build hundreds of thousands of units annually.

The Signature Editions served as a final “runout” series: 250 for the Model S and only 100 for the Model X, all built to the highest Plaid specification before the line is converted.

Deliveries of the remaining Signature units are scheduled to begin in May 2026. For buyers who secured one, it’s the ultimate swan song for a vehicle that helped define Tesla’s early luxury EV dominance.

Launched in 2015, the Model X introduced falcon-wing doors, a panoramic windshield, and class-leading performance that turned heads and set benchmarks. While newer models like the Cybertruck and refreshed Model Y have taken center stage, the Model X Plaid remained a halo product for those seeking maximum range, space, and speed in an SUV package.

With inventory of standard Model X units already nearly exhausted across the U.S., the rapid sell-out of the Signature Edition underscores enduring demand for Tesla’s premium flagships even as the company pivots toward robotics and autonomy.

For enthusiasts, these 100 garnet-red SUVs will likely become instant collector’s items—tangible reminders of the vehicles that built the brand before Tesla’s next chapter fully begins. The last chance is gone, but the legacy endures.

Tesla Optimus V3 hand and arm details revealed in new patents

Two new patents, which were coincidentally filed on the same day as the “We, Robot” event back in October 2024, protect Tesla’s mechanically actuated, tendon-driven architecture.

Tesla is planning to soon reveal its latest and greatest version of the Optimus humanoid robot, and a series of new patents for the hands and arms, with the former being, admittedly, one of the most challenging parts of developing the project.

Two new patents, which were coincidentally filed on the same day as the “We, Robot” event back in October 2024, protect Tesla’s mechanically actuated, tendon-driven architecture.

The designs relocate heavy actuators to the forearm, route cables through a sophisticated wrist design, and employ innovative joint assemblies to achieve human-like dexterity while enabling lightweight construction and high-volume manufacturing.

Core Tendon-Driven Hand Architecture

The primary patent, which is titled “Mechanically Actuated Robotic Hand,” details a cable/tendon-driven system.

Actuators are positioned in the forearm rather than the hand. Each finger features four degrees of freedom (DoF), while the wrist adds two more.

Three thin, flexible control cables (tendons) per finger extend from the forearm actuators, pass through the wrist, and connect to the finger segments. Integrated channels within the finger phalanges guide these cables selectively—routing behind some joints and forward of others—to enable independent bending without unintended motion.

Patent diagrams illustrate thick cable bundles emerging from the wrist into the palm and fingers, with labeled pivots and routing guides. This setup closely mirrors human forearm-muscle and tendon anatomy, where most hand control originates proximally.

Advanced Wrist Routing Innovation

One of the standout features is the wrist’s cable transition mechanism. Cables shift from a lateral stack on the forearm side to a vertical stack on the hand side through a specialized transition zone.

This geometry significantly reduces cable stretch, torque, friction, and crosstalk during combined yaw and pitch wrist movements — common failure points in simpler tendon systems that cause imprecise or jerky motion.

By minimizing these issues, the design supports smoother, more reliable multi-axis wrist operation, essential for complex real-world tasks.

Companion Patents on Appendage and Joint Design

Two supporting patents provide additional depth. “Robotic Appendage” covers the overall forearm-to-palm-to-finger assembly, with a palm body movably coupled to the forearm and finger phalanges linked by tensile cables returning to forearm actuators. Tensioning these cables repositions the phalanges precisely.

“Joint Assembly for Robotic Appendage” describes curved contact surfaces on mating structures paired with a composite flexible member. This allows smooth pivoting while maintaining consistent tension, enhancing durability, and simplifying assembly for mass production.

Executive Insights on Hand Development Challenges

Tesla executives have consistently described the hand as the most difficult component of Optimus.

Elon Musk has called it “the majority of the engineering difficulty of the entire robot,” emphasizing that human hands possess roughly 27–28 DoF with an intricate tendon network powered largely by forearm muscles. He has likened the challenge to something “harder than Cybertruck or Model X… somewhere between Model X and Starship.”

Elon Musk shares ridiculous fact about Optimus’ hand demos

In mid-2025, Musk acknowledged that Tesla was “struggling” to finalize the hand and forearm design. By early 2026, he stated that the company had overcome the “hardest” problems, including human-level manual dexterity, real-world AI integration, and volume production scalability.

He estimated the electromechanical hand represents about 60 percent of the overall Optimus challenge, compounded by the lack of an existing supply chain for such precision components.

These patents directly tackle the acknowledged pain points: relocating actuators reduces hand mass and inertia for better speed and efficiency; advanced wrist routing and joint geometry address friction and crosstalk; and simplified, stackable parts visible in the diagrams indicate readiness for high-volume manufacturing.

Implications for Optimus Production and Leadership

Collectively, the patents portray the Optimus v3 hand not as a mere prototype, but as a production-oriented system engineered from first principles.

The 22-DoF architecture, forearm-driven tendons, and crosstalk-minimizing wrist deliver a clear competitive edge in dexterity. They align with Musk’s view that high-volume manufacturing is one of the three critical elements missing from most other humanoid projects.

For Optimus to become the most capable humanoid robot, its hand needed to replicate the useful and applicable design of the human counterpart.

These filings demonstrate that Tesla has transformed years of engineering challenges into patented, elegant solutions — positioning the company strongly in the race toward general-purpose robotics.
