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.

What is Digital Optimus? The new Tesla and xAI project explained
At its core, Digital Optimus operates through a dual-process architecture inspired by human cognition.
Tesla and xAI announced their groundbreaking joint project, Digital Optimus, also nicknamed “Macrohard” in a humorous jab at Microsoft, earlier this week.
This software-based AI agent is designed to automate complex office workflows by observing and replicating human interactions with computers. As the first major outcome of Tesla’s $2 billion investment in xAI, it represents a powerful fusion of hardware efficiency and advanced reasoning.
At its core, Digital Optimus operates through a dual-process architecture inspired by human cognition.
Macrohard or Digital Optimus is a joint xAI-Tesla project, coming as part of Tesla’s investment agreement with xAI.

Tesla’s specialized AI acts as “System 1”—the fast, instinctive executor—processing the past five seconds of real-time computer screen video along with keyboard and mouse actions to perform immediate tasks.
xAI’s Grok model serves as “System 2,” the strategic “master conductor” or navigator, providing high-level reasoning, world understanding, and directional oversight, much like an advanced turn-by-turn navigation system.
When combined, the two can create a powerful AI-based assistant that can complete everything from accounting work to HR tasks.
Will Tesla join the fold? Predicting a triple merger with SpaceX and xAI
The system runs primarily on Tesla’s low-cost AI4 inference chip, minimizing expensive Nvidia resources from xAI for competitive, real-time performance.
Elon Musk described it as “the only real-time smart AI system” capable, in principle, of emulating the functions of entire companies, handling everything from accounting and HR to repetitive digital operations.
Timelines point to swift deployment. Announced just days ago, Musk expects Digital Optimus to be ready for user experience within about six months, targeting rollout around September 2026.
It will integrate into all AI4-equipped Tesla vehicles, enabling parked cars to handle office work during downtime. Millions of dedicated units are also planned for deployment at Supercharger stations, tapping into roughly 7 gigawatts of available power.
Oh and it works in all AI4-equipped cars, so your car can do office work for you when not driving.
We’re also deploying millions of dedicated Digital Optimus units in the field at Superchargers where we have ~7 gigawatts of available power.

Digital Optimus directly supports Tesla’s broader autonomy strategy. It leverages the same end-to-end neural networks, computer vision, and real-time decision-making tech that power Full Self-Driving (FSD) software and the physical Optimus humanoid robot.
By repurposing idle vehicle compute and extending AI4 hardware beyond driving, the project scales Tesla’s autonomy ecosystem from roads to digital workspaces.
As a virtual counterpart to physical Optimus, it divides labor: software agents manage screen-based tasks while humanoid robots tackle physical ones, accelerating Tesla’s vision of general-purpose AI for productivity, Robotaxi fleets, and beyond.
In essence, Digital Optimus bridges Tesla’s vehicle and robotics autonomy with enterprise-scale AI, promising massive efficiency gains. No other company currently matches its real-time capabilities on such accessible hardware.
It really could be one of the most crucial developments Tesla and xAI begin to integrate, as it could revolutionize how people work and travel.

Tesla adds awesome new driving feature to Model Y
Tesla is rolling out a new “Comfort Braking” feature with Software Update 2026.8. The feature is exclusive to the new Model Y, and is currently unavailable for any other vehicle in the Tesla lineup.
Tesla is adding an awesome new driving feature to Model Y vehicles, effective on Juniper-updated models considered model year 2026 or newer.
Tesla is rolling out a new “Comfort Braking” feature with Software Update 2026.8. The feature is exclusive to the new Model Y, and is currently unavailable for any other vehicle in the Tesla lineup.
Tesla writes in the release notes for the feature:
“Your Tesla now provides a smoother feel as you come to a complete stop during routine braking.”

Interestingly, we’re not too sure what catalyzed Tesla to try to improve braking smoothness, because it hasn’t seemed overly abrupt or rough from my perspective. Although the brake pedal in my Model Y is rarely used due to Regenerative Braking, it seems Tesla wanted to try to make the ride comfort even smoother for owners.
There is always room for improvement, though, and it seems that there is a way to make braking smoother for passengers while the vehicle is coming to a stop.
This is far from the first time Tesla has attempted to improve its ride comfort through Over-the-Air updates, as it has rolled out updates to improve regenerative braking performance, handling while using Full Self-Driving, improvements to Steer-by-Wire to Cybertruck, and even recent releases that have combatted Active Road Noise.
Tesla holds a unique ability to change the functionality of its vehicles through software updates, which have come in handy for many things, including remedying certain recalls and shipping new features to the Full Self-Driving suite.
Tesla seems to have the most seamless OTA processes, as many automakers have the ability to ship improvements through a simple software update.
We’re really excited to test the update, so when we get an opportunity to try out Comfort Braking when it makes it to our Model Y.

Tesla finally brings a Robotaxi update that Android users will love
The breakdown of the software version shows that Tesla is actively developing an Android-compatible version of the Robotaxi app, and the company is developing Live Activities for Android.
Tesla is finally bringing an update of its Robotaxi platform that Android users will love — mostly because it seems like they will finally be able to use the ride-hailing platform that the company has had active since last June.
Based on a decompile of software version 26.2.0 of the Robotaxi app, Tesla looks to be ready to roll out access to Android users.
According to the breakdown, performed by Tesla App Updates, the company is preparing to roll out an Android version of the app as it is developing several features for that operating system.
🚨 It looks like Tesla is preparing to launch the Robotaxi app for Android users at last!

The breakdown of the software version shows that Tesla is actively developing an Android-compatible version of the Robotaxi app, and the company is developing Live Activities for Android:
“Strings like notification_channel_robotaxid_trip_name and android_native_alicorn_eta_text show exactly how Tesla plans to replicate the iOS Live Activities experience. Instead of standard push alerts, Android users are getting a persistent, dynamically updating notification channel.”
This is a big step forward for several reasons. From a face-value perspective, Tesla is finally ready to offer Robotaxi to Android users.
The company has routinely prioritized Apple releases because there is a higher concentration of iPhone users in its ownership base. Additionally, the development process for Apple is simply less laborious.
Tesla is working to increase Android capabilities in its vehicles
Secondly, the Robotaxi rollout has been a typical example of “slowly then all at once.”
Tesla initially released Robotaxi access to a handful of media members and influencers. Eventually, it was expanded to more users, so that anyone using an iOS device could download the app and hail a semi-autonomous ride in Austin or the Bay Area.
Opening up the user base to Android users may show that Tesla is preparing to allow even more users to utilize its Robotaxi platform, and although it seems to be a few months away from only offering fully autonomous rides to anyone with app access, the expansion of the user base to an entirely different user base definitely seems like its a step in the right direction.
