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-

Elon Musk reveals shocking Tesla Optimus patent detail
What looked promising on paper and in simulations failed to deliver the reliability required for a robot expected to handle delicate tasks like folding laundry, assembling electronics, or assisting in factories and homes.
Elon Musk revealed a shocking detail on the Tesla Optimus patent that was revealed last week. Despite it being made public for the first time, Musk said the company has already moved on from the design, an incredible truth about the development of new technology: things move fast.
Musk dropped a bombshell about the Tesla Optimus humanoid robot hand patent that was released last week. Musk, candidly replying to a post late at night on X, revealed that what is a new technology to many fans and insiders is actually old news to those developing the tech directly.
“We already changed the design,” Musk said. “This one didn’t actually work.”
We already changed the design. This one didn’t actually work.

Patents, after all, are often viewed as blueprints for future products. Yet Musk revealed that the rolling contact mechanism—intended to provide smooth, low-friction articulation in the fingers—had already been scrapped after real-world testing exposed its shortcomings.
What looked promising on paper and in simulations failed to deliver the reliability required for a robot expected to handle delicate tasks like folding laundry, assembling electronics, or assisting in factories and homes.
The hand has been one of the biggest challenges for Tesla engineers since Optimus development started years ago. Musk has said that there is not enough recognition for how incredible and useful the human hand is, and designing one for a humanoid robot has been the biggest challenge of all.
Tesla is stumped on how to engineer this Optimus part, but they’re close
This moment underscores the persistent engineering hurdles in achieving reliable humanoid hand dexterity. Human fingers are marvels of evolution: 27 bones, intricate tendons, ligaments, and a network of sensors working in perfect harmony. Replicating that in metal and silicon is extraordinarily difficult.
Rolling contacts promised reduced wear and precise motion, but testing likely revealed issues with durability under repeated stress, grip stability on varied surfaces, or the micro-precision needed for fine motor skills.
These aren’t minor tweaks, but instead they represent fundamental challenges that have plagued robotics teams for decades. Even advanced competitors struggle here—hands remain the Achilles’ heel of most humanoids because the margin for error is razor-thin.
A fraction of a millimeter off, and a robot drops a glass or fails to button a shirt.
What makes Musk’s reply remarkable is how it signals Tesla’s direct communication style on prototype limitations. While many companies guard failures behind glossy marketing and vague timelines, Tesla openly shares setbacks.
Musk was forthcoming about the failure of this recent design. This transparency builds trust with investors, engineers, and fans. It shows Tesla treats Optimus development like true science: rapid iteration, rigorous testing, and zero tolerance for hype that doesn’t match reality.
The disclosure from Musk also highlights Tesla’s blistering pace of development. By the time the patents are published, which is often over a year after the initial filing, the technology has already evolved.
Optimus is far from a static product, and it’s a living project advancing weekly.
In the high-stakes race for general-purpose robots, Tesla’s approach stands out. Admitting a finger-joint design “didn’t actually work” isn’t a weakness—it’s confidence.
True innovation demands confronting failure head-on, and Musk just reminded the world that Optimus is being engineered that way. The next version of those hands is already in testing, and it will be better because Tesla isn’t afraid to say what didn’t work.

Tesla is sending its humanoid Optimus robot to the Boston Marathon
Tesla’s Optimus robot is heading to the Boston Marathon finish line
Tesla’s Optimus humanoid robot will be stationed at the Tesla showroom at 888 Boylston Street in Boston, right along the final stretch of the Boston Marathon today, ready to cheer on runners and pose for photos with spectators.
According to a Tesla email shared by content creator Sawyer Merritt on X, Optimus will be at the Boston Boylston Street showroom on April 20, coinciding with Marathon Monday weekend. The Boston Marathon finishes on Boylston Street, and the surrounding area draws hundreds of thousands of spectators along with international broadcast coverage. Placing Optimus there puts it in front of a massive public audience at zero advertising cost.
Just got this email. @Tesla’s Optimus robot is coming to Boston.

The Tesla showroom is at 888 Boylston Street, between Gloucester Street and Fairfield Street. The final mile of the marathon runs directly along Boylston Street, with runners passing the big stores before reaching the finish line at Copley Square.
Optimus was first announced at Tesla’s AI Day event on August 19, 2021, when Elon Musk presented a vision for a general-purpose robot designed to take on dangerous, repetitive, and unwanted tasks. In March 2026, Optimus appeared at the Appliance and Electronics World Expo in Shanghai, where on-site staff stated that mass production of the robot could begin by the end of 2026. Before that, it showed up at the Tesla Hollywood Diner opening in July 2025 and at a Miami showroom event in December 2025.
Tesla’s well-calculated display of Optimus gives the public a low-pressure first encounter with a robot that Tesla is preparing to soon deploy at scale. The company has previously indicated plans to manufacture Optimus robots at its Fremont facility at up to 1 million units annually, with an Optimus production line at Gigafactory Texas targeting 10 million units per year.

Musk has said that Optimus “has the potential to be more significant than the vehicle business over time,” and separately that roughly 80 percent of Tesla’s future value will come from the robot program. Whether that holds depends on production execution. For now, Boston gets a preview of what that future looks like, standing at the finish line on Boylston Street while 32,000 runners pass by.

Tesla expands Unsupervised Robotaxi service to two new cities
This expansion builds directly on Tesla’s existing operations. Robotaxi has been ramping unsupervised rides in Austin for months and maintains activity in the San Francisco Bay Area.
Tesla has taken a major step forward in its autonomous ride-hailing ambitions.
On April 18, the company’s official Robotaxi account announced that Robotaxi service is now rolling out in Dallas and Houston, Texas. The update signals the rapid scaling of unsupervised autonomous operations in the Lone Star State.
The announcement includes a compelling 14-second video captured from inside a Model Y. Shot from the passenger perspective, the footage shows the vehicle navigating suburban roads in both cities with zero driver intervention, with no Safety Monitor to be seen.

This expansion builds directly on Tesla’s existing operations. Robotaxi has been ramping unsupervised rides in Austin for months and maintains activity in the San Francisco Bay Area.
With Dallas and Houston now live, Texas hosts three active hubs—an impressive concentration that triples the company’s Lone Star footprint in just weeks. The move aligns with Tesla’s Q4 2025 earnings guidance, which outlined a broader H1 2026 rollout across seven U.S. cities, including Phoenix, Miami, Orlando, Tampa, and Las Vegas.
Texas offers favorable regulations, high ride-share demand, and relatively straightforward suburban-to-urban driving patterns ideal for early autonomous scaling. While initial geofences appear modest—roughly 25 square miles per city—Tesla has historically expanded these zones quickly as it gathers real-world data.
Tesla confirms Robotaxi expansion plans with new cities and aggressive timeline
Unsupervised operation marks a critical milestone: passengers can summon, ride, and exit without safety drivers, a leap beyond many competitors still requiring human oversight.
For Tesla, the implications are significant. Successful scaling in major metros could accelerate the transition to a fully driverless fleet, unlocking new revenue streams and validating years of Full Self-Driving investment.
Riders gain convenient, potentially lower-cost mobility, while the company edges closer to Elon Musk’s vision of Robotaxis transforming urban transport.
As Tesla pushes into more cities this year, today’s launch in Dallas and Houston underscores its momentum. Hopefully, Tesla will be able to expand unsupervised rides to another U.S. state soon, which will mark yet another chapter in this short-but-encouraging Robotaxi story.
