SpaceX Starlink partners with Microsoft Azure to deploy cloud computing anywhere
Microsoft Azure has announced a partnership with SpaceX that will give customers the ability to both access and deploy cloud computing capabilities anywhere on Earth with the help of Starlink internet.
Ultimately designed with anywhere from ~4,400 to ~40,000 operational satellites in mind, SpaceX’s Starlink constellation aims to connect users to the internet where existing access is either too expensive, limited, or completely unavailable. Of course, however, connecting the world’s unconnected is an immense and challenging aspiration – one that is unlikely to be one of the Starlink constellation’s first major uses.
As CEO Elon Musk has been keen to regularly note, the real challenge of SpaceX’s Starlink satellite internet project is ultimately ensuring that the constellation doesn’t join the graveyard of bankrupt companies that came before it. For better or worse, that will necessitate close relationships with as many premium enterprise-class customers as possible. With its estimated 2020 market cap of ~$370 billion expected to grow to ~$800 billion or more by 2025, cloud computing is one such potentially lucrative application.
To better exploit the benefits offered by the kind of blanket connectivity Starlink may soon offer, Microsoft has developed its own Azure Modular Datacenter (MDC), essentially a data center built into a mobile, satellite-connected shipping container. Customers can choose to either use the MDC as a wholly independent datacenter or connect it to one or more satellite constellations, Starlink included. With what a SpaceX executive recently described as dual parabolic antennas, an MDC could likely have access to gigabit-class internet connectivity with latency comparable to fiber anywhere on Earth.
According to Microsoft, possible scenarios where an MDC would be valuable include “mobile command centers, humanitarian assistance, military mission needs, mineral exploration, and other use cases requiring high intensity, secure computing.” Several Azure Mobile Datacenters have already been deployed and are being trialed by private sector companies and the US military.
Likely less than coincidental, Microsoft Azure’s Starlink partnership comes around the same time as Amazon has begun to peel back the curtains on Project Kuiper, a low Earth orbit (LEO) satellite internet constellation almost indistinguishable from Starlink. Lead and largely staffed by former Starlink executives and employees, Project Kuiper aims to deploy a constellation of ~3200 small, interlinked communications satellites – a goal Amazon has pledged at least $10 billion to achieve.
Somewhat unsurprisingly, Kuiper – lead by executives SpaceX CEO Elon Musk personally fired in 2019 for moving too slowly – has no set schedule or indication of early prototype development and is effectively 3-5 years behind SpaceX, OneWeb, and other prospective constellation operators from the get-go.
An IEEE Spectrum article offers an excellent summary of the web services. logistics, and online shopping giant’s most likely motivation behind investing so much money in a satellite constellation that is – at best – years behind.
“‘With Amazon, it’s a whole different ballgame,’ says Zac Manchester, an assistant professor of aeronautics and astronautics at Stanford University. ‘The thing that makes Amazon different from SpaceX and OneWeb is they have so much other stuff going for them.’ If Kuiper succeeds, Amazon can not only offer global satellite broadband access—it can include that access as part of its Amazon Web Services (AWS), which already offers resources for cloud computing, machine learning, data analytics, and more.”
Michael Koziol – IEEE Spectrum – 17 August 2020
In other words, Amazon likely believes that its potential advantages are so strong and so unmatched that it doesn’t matter if it’s years late to the party. On the other hand, it could also be the case that Amazon – and Amazon Web Services in particular – perceives a lack of the capabilities offered by a high-bandwidth satellite internet constellation to be such an existential threat that the company has no choice but to try to enter the fray.
As such, SpaceX’s partnership with Microsoft Azure Cloud Services is a direct shot across Amazon’s bow, demonstrating that even if Project Kuiper manages to begin operational satellite launches in just a year or two, the company will immediately face experienced, organized competition. There is some level of irony in the fact that, purely out of corporate spite, Amazon will now likely never become a Starlink customer to avoid helping a direct competitor, meaning that AWS will be consciously putting itself at a competitive disadvantage for years to come by waiting for Project Kuiper.

Tesla confirms that it finally solved its 4680 battery’s dry cathode process
The suggests the company has finally resolved one of the most challenging aspects of its next-generation battery cells.
Tesla has confirmed that it is now producing both the anode and cathode of its 4680 battery cells using a dry-electrode process, marking a key breakthrough in a technology the company has been working to industrialize for years.
The update, disclosed in Tesla’s Q4 and FY 2025 update letter, suggests the company has finally resolved one of the most challenging aspects of its next-generation battery cells.
Dry cathode 4680 cells
In its Q4 and FY 2025 update letter, Tesla stated that it is now producing 4680 cells whose anode and cathode were produced during the dry electrode process. The confirmation addresses long-standing questions around whether Tesla could bring its dry cathode process into sustained production.
The disclosure was highlighted on X by Bonne Eggleston, Tesla’s Vice President of 4680 batteries, who wrote that “both electrodes use our dry process.”
Tesla first introduced the dry-electrode concept during its Battery Day presentation in 2020, pitching it as a way to simplify production, reduce factory footprint, lower costs, and improve energy density. While Tesla has been producing 4680 cells for some time, the company had previously relied on more conventional approaches for parts of the process, leading to questions about whether a full dry-electrode process could even be achieved.
4680 packs for Model Y
Tesla also revealed in its Q4 and FY 2025 Update Letter that it has begun producing battery packs for certain Model Y vehicles using its in-house 4680 cells. As per Tesla:
“We have begun to produce battery packs for certain Model Ys with our 4680 cells, unlocking an additional vector of supply to help navigate increasingly complex supply chain challenges caused by trade barriers and tariff risks.”
The timing is notable. With Tesla preparing to wind down Model S and Model X production, the Model Y and Model 3 are expected to account for an even larger share of the company’s vehicle output. Ensuring that the Model Y can be equipped with domestically produced 4680 battery packs gives Tesla greater flexibility to maintain production volumes in the United States, even as global battery supply chains face increasing complexity.

Tesla Giga Texas to feature massive Optimus V4 production line
This suggests that while the first Optimus line will be set up in the Fremont Factory, the real ramp of Optimus’ production will happen in Giga Texas.
Tesla will build Optimus 4 in Giga Texas, and its production line will be massive. This was, at least, as per recent comments by CEO Elon Musk on social media platform X.
Optimus 4 production
In response to a post on X which expressed surprise that Optimus will be produced in California, Musk stated that “Optimus 4 will be built in Texas at much higher volume.” This suggests that while the first Optimus line will be set up in the Fremont Factory, and while the line itself will be capable of producing 1 million humanoid robots per year, the real ramp of Optimus’ production will happen in Giga Texas.
This was not the first time that Elon Musk shared his plans for Optimus’ production at Gigafactory Texas. During the 2025 Annual Shareholder Meeting, he stated that Giga Texas’ Optimus line will produce 10 million units of the humanoid robot per year. He did not, however, state at the time that Giga Texas would produce Optimus V4.
“So we’re going to launch on the fastest production ramp of any product of any large complex manufactured product ever, starting with building a one-million-unit production line in Fremont. And that’s Line one. And then a ten million unit per year production line here,” Musk stated.
How big Optimus could become
During Tesla’s Q4 and FY 2025 earnings call, Musk offered additional context on the potential of Optimus. While he stated that the ramp of Optimus’ production will be deliberate at first, the humanoid robot itself will have the potential to change the world.
“Optimus really will be a general-purpose robot that can learn by observing human behavior. You can demonstrate a task or verbally describe a task or show it a task. Even show it a video, it will be able to do that task. It’s going to be a very capable robot. I think long-term Optimus will have a very significant impact on the US GDP.
“It will actually move the needle on US GDP significantly. In conclusion, there are still many who doubt our ambitions for creating amazing abundance. We are confident it can be done, and we are making the right moves technologically to ensure that it does. Tesla, Inc. has never been a company to shy away from solving the hardest problems,” Musk stated.

Rumored SpaceX-xAI merger gets apparent confirmation from Elon Musk
The comment follows reports that the rocket maker is weighing a transaction that could further consolidate Musk’s space and AI ventures.
Elon Musk appeared to confirm reports that SpaceX is exploring a potential merger with artificial intelligence startup xAI by responding positively to a post about the reported transaction on X.
Musk’s comment follows reports that the rocket maker is weighing a transaction that could further consolidate his space and AI ventures.
SpaceX xAI merger
As per a recent Reuters report, SpaceX has held discussions about merging with xAI, with the proposed structure potentially involving an exchange of xAI shares for SpaceX stock. The value, structure, and timing of any deal have not been finalized, and no agreement has been signed.
Musk appeared to acknowledge the report in a brief reply on X, responding “Yeah” to a post that described SpaceX as a future “Dyson Swarm company.” The comment references a Dyson Swarm, a sci-fi megastructure concept that consists of a massive network of satellites or structures that orbit a celestial body to harness its energy.
Reuters noted that two entities were formed in Nevada on January 21 to facilitate a potential transaction for the possible SpaceX-xAI merger. The discussions remain ongoing, and a transaction is not yet guaranteed, however.
AI and space infrastructure
A potential merger with xAI would align with Musk’s stated strategy of integrating artificial intelligence development with space-based systems. Musk has previously said that space-based infrastructure could support large-scale computing by leveraging continuous solar energy, an approach he has framed as economically scalable over time.
xAI already has operational ties to Musk’s other companies. The startup develops Grok, a large language model that holds a U.S. Department of Defense contract valued at up to $200 million. AI also plays a central role in SpaceX’s Starlink and Starshield satellite programs, which rely on automation and machine learning for network management and national security applications.
Musk has previously consolidated his businesses through share-based transactions, including Tesla’s acquisition of SolarCity in 2016 and xAI’s acquisition of X last year. Bloomberg has also claimed that Musk is considering a merger between SpaceX and Tesla in the future.
