SpaceX closes out 2021 with $1.85 billion in new funding
On the eve of the last day of 2021, SEC filings show that SpaceX has secured another $337 million, bringing the total funding the company has raised this year to approximately $1.85 billion.
While there’s evidence that SpaceX’s Falcon and Dragon launch business is easily profitable on its own, the company has been simultaneously developing a next-generation rocket (Starship) and an unprecedentedly ambitious internet satellite constellation (Starlink) for at least the last 5-6 years. Additionally, SpaceX developed Falcon booster reusability and Falcon Heavy entirely on its own at a total cost of at least $1-2 billion. In short, rocket development is incredibly expensive, and adding a far more ambitious rocket and an immense satellite constellation into the mix has created an insatiable demand for fresh capital.
Investors have been more than eager to satisfy that demand, practically chomping at the bit to buy SpaceX equity or debt over the last six years. Since 2015, SpaceX has raised an average of more than $1B per year for the last seven years.


That funding has accomplished a great deal. As of the end of 2021, SpaceX has built and launched 1869 operational Starlink satellites in 25 months, more than 1750 of which are still in orbit and working. SpaceX has also built hundreds of thousands of ‘user terminals’ – dishes and WiFi routers that currently connect more than 150,000 subscribers to the internet even while the service remains in beta.
Starship, while somewhat behind its CEO’s optimistic schedules, continues to march towards its first spaceflight and orbital-velocity launch attempt – possibly in the first half of 2022. With help from its Hawthorne, CA headquarters, SpaceX’s Starbase factory continues to churn out Starship, Super Heavy booster, and test tank prototypes and appears to be ramping back up after six or so months of relative quiet. Having produced approximately 150 Raptor 1 and Raptor 1.5 engines in the last two years, Hawthorne is now focused on ramping up production of Raptor 2 – an upgraded engine variant capable of producing up to 25% more thrust while, in theory, being far cheaper to produce.
In about 12 months, SpaceX has also built – from nothing – an orbital launch site on the verge of being ready to support the first test flights of the largest, heaviest, and most powerful rocket ever built. To accommodate the massive vehicle, SpaceX has also nearly completed the largest cryogenic tank farm ever built for a launch site and partially filled at least four or five of its seven cryogenic storage tanks. Alongside that tank farm, the company has more or less completed a skyscraper-sized launch tower and outfitted it with three giant, moving arms – two of which are designed to stack Starship on Super Heavy and, maybe one day, catch ships and boosters out of mid-air.
According to a company-wide email CEO Elon Musk recently wrote but subsequently downplayed on Twitter, SpaceX’s financial health could be heavily dependent on the successful start and expansion of Raptor 2 production to enable Starship to begin launching new and much-improved Starlink V2.0 satellites. Those satellites are several times larger than V1.0 or V1.5 spacecraft, apparently making it hard or impossible for Falcon 9 to cost-effectively launch them.
On top of building and activating new factories capable of producing millions of Starlink user terminals per year, completing the first phase of orbital Starship development, ramping up Raptor 2 production, starting to build a fleet of operational Starships and Super Heavy boosters, continuing Falcon 9 Starlink V1.5 launches, and simultaneously building or completing no less than three orbital Starship launch sites in Florida and Texas, SpaceX thus also apparently needs to complete Starlink V2.0 satellite development and effectively build one or several entirely new production lines to start producing the substantially different spacecraft.
A large portion of SpaceX’s 2021 funding – especially the ~$337M raised in the last two weeks – will likely help support a portion of all those development efforts next year.

Tesla Q1 Earnings: What Elon Musk and Co. will answer during the call
Tesla (NASDAQ: TSLA) is set to hold its Earnings Call for the first quarter of 2026 on Wednesday, and there are a lot of interesting things that are swirling around in terms of speculation from investors.
With the company’s executives, including CEO Elon Musk, answering a handful of questions that investors submit through the Say platform, fans want to know a lot of things about a lot of things.
These five questions come from Retail Investors, who are normal, everyday shareholders:
- When will we have the Optimus v3 reveal? When will Optimus production start, since we ended the Model S and Model X production earlier than mid-year? What’s the expected Optimus production rate exiting this year? What are the initial targeted skills?
- What milestones are you targeting for unsupervised FSD and Robotaxi expansion beyond Austin this year, and how will that drive recurring revenue?
- How will Hardware 3 cars reach Unsupervised Full Self-Driving?
- When do you expect Unsupervised Full Self-Driving to reach customer cars?
- When will Robotaxi expand past its current limited rollout?
Additionally, these are currently the three questions that are slated to be answered by Institutional Firms, which also answer a handful of questions during the call:
- Now that FSD has been approved in the Netherlands and is expected to launch across Europe this summer, can you discuss your Robotaxi strategy for the region?
- What enabled you to finish the AI5 tapeout early and were there any changes to the original vision? Last week, Elon said AI5 will go into Optimus and the Supercomputer, but one month ago said it would go into the Robotaxi. Has AI5 been dropped from the vehicle roadmap?
- Given the recent NHTSA incident filings, can you update us on the Robotaxi safety data? If safety validation remains the primary bottleneck, why not deploy thousands of vehicles to accelerate the removal of the safety driver?
The questions range through every current Tesla project, including FSD expansion and Optimus. However, many of the answers we will get will likely be repetitive answers we’ve heard in the past.
This is especially pertinent when the questions about when Unsupervised FSD will reach customer cars: we know Musk will say that it will happen this year. Is Tesla capable of that? Maybe. But a more transparent answer that is more revealing of a true timeline would be appreciated.
Hardware 3 owners are anxiously awaiting the arrival of FSD v14 Lite, which was promised to them last year for a release sometime this year.
The Earnings Call is set to take place on Wednesday at market close.

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.
