SpaceX preps second $500M fundraiser as Starlink & Starship make progress
According to regulatory documents seen by Prime Unicorn Index, SpaceX finished a $500M funding round begun in December 2018 and kicked off a second campaign seeking an additional $500M earlier this month.
Altogether, SpaceX appears to be on track to secure $1 billion in fresh capital in the last six months alone, a trend that that may well continue as the company pushes forth into new and capital-intensive phases of Starlink and Starship development. In Boca Chica, a flood of SpaceX engineers and technicians have descended on the area to build the first full-scale steel prototypes of Starship and the major facilities needed to support the vehicles, all from scratch. Across the West Coast of the US, a separate SpaceX team has simultaneously transitioned from prototyping and developing satellites to building a factory to mass-produce them and may be less than six weeks away from launching the first operational batch of Starlink spacecraft.
Giant rockets, giant funding
Both massive, perilous, and largely unprecedented ventures in their own right, Starship (formerly BFR) and Starlink also happen to be extremely capital-intensive, a more or less fundamental consequence of the stages of their development and expansion. Both spent many years in pure research and development phases, tinkering and experimenting with different ideas and technologies on the ground in an effort to conceptualize what exactly their final forms ought to be. This aspect of the BFR program has been extremely visible over the last three years as SpaceX and CEO Elon Musk’s goals underwent continuous semi-annual changes, often intentionally broadcasted to the public in
After appearing to finally settle on the quasi-final form of BFR (renamed to Starship/Super Heavy), SpaceX has actually begun to build and test the first full-scale, integrated prototype of the spacecraft (Starhopper) and is simultaneously building what aims to be the first orbital Starship prototype. At the same time, its propulsion system of choice – known as Raptor – has entered into serial production back at SpaceX’s Hawthorne factory, while also supporting the first Starhopper hop test in early April and preparing to continue separate ground testing.

Thousands of satellites, billions of dollars
In February 2018, SpaceX successfully launched its first Starlink satellites, two prototypes meant to test a bevy of technologies the company was attempting to build (or at least utilize) for the first time. Despite hints and reports of some problems on orbit, SpaceX firmly holds that both satellites were extremely successful in their task of proving out new technologies like electric thrusters and phased-array antennas and are still safely operating today. Just four months after those prototypes launched, CEO Elon Musk took the extraordinary step of flying to Redmond, Washington to personally challenge a number of executives he believed were operating far too sluggishly. According to secondhand reports, many of them refused to expedite the program as Musk wanted them to, resulting in their immediate firings. The challenge that triggered the organizational upheaval: launch the first operational batch of Starlink satellites before the end of June 2019, twelve months away at the time.
Five months after Musk’s challenge, SpaceX submitted a request to the FCC to modify its original Starlink constellation license, halving the orbit of the first thousand or so satellites to 550 km (340 mi) and significantly simplifying the technology on the first several dozen to be launched. As a result of the strategic changes made, SpaceX is already planning to launch its first group of Starlink satellites as early as mid-May, with perhaps one or several additional launches on the books for 2019. To an extent, the first 75 Starlink satellites and their six ground stations will be a nearly full-fidelity second prototype. Instead of a minimalist development platform like Tintin A and B, the first 75 satellites should offer opportunities to actually test the operations of a large constellation of spacecraft while also demonstrating something close to the internet connectivity the full constellation is meant to offer.

Development to production
That SpaceX is attempting to raise huge amounts of capital should come as no surprise. For almost any commercial venture on Earth that is attempting to introduce a real product from nothing, the process of going from concept, design, and testing to building a final product at scale is both extraordinarily difficult and extremely expensive. Tesla famously went through “manufacturing hell” to go from Model 3 prototypes to a mass-producible finished product, while countless other ventures don’t even make it that far (i.e. vaporware). By far the most challenging aspect of this transition is moving from a phase focused predominately on development to one focused predominately on production.
Due to an extremely unorthodox approach to building the first steel Starship and Super Heavy prototypes, quite literally choosing to do so outside and without shelter, the BFR program is probably less extreme for the time being. However, the transformation needed for Starlink to progress is intense, requiring the satellite team to essentially build a factory from scratch and begin mass-producing high-performance satellites as quickly as possible. The 75-satellite buffer should ease the pain a bit and offer a sort of trial run as SpaceX makes that major transition, but the fact remains that an unprecedented number (thousands) of satellites will need to be built and launched at an equally unprecedented pace and cost-per-unit.

The $500M raised since December 2018 will likely be a major help for SpaceX’s often-

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.
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.
Tesla’s Optimus V3 robot hand looks to have been revealed in a new international patent published today.
The patent describes a tendon/cable-driven hand:
• Actuators in the forearm
• Each finger has 4 degrees of freedom
• The wrist has 2 degrees of freedom
• Tendon-driven… pic.twitter.com/eE8xLEYSrx— Sawyer Merritt (@SawyerMerritt) April 16, 2026
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.
Boom! @Tesla_Optimus 의 3세대 구조로 추정되는, 로봇 팔 및 관절에 대한 특허가 공개되었습니다.
아티클 작업에 들어가겠습니다.
1년 넘게 기다려 온, 정말 귀한 특허인데, 조회수 100만대로 터져줬으면 좋겠네요. 😉@herbertong @SawyerMerritt@GoingBallistic5 @TheHumanoidHub pic.twitter.com/CCEiIlMFSX

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.”
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.
