SpaceX contemplates Mars rocket factory on the South Texas coast
In statements provided to the Brownsville Herald, a Texan paper dedicated to a South Texas region that includes SpaceX’s Boca Chica launch site, state representative René Oliveira hinted that SpaceX’s plans for the region could go “well beyond conducting launches.”
SpaceX and South Texas
The Herald’s Steve Clark provided a great summary of the history between SpaceX and Texas in recent years, particularly related to the company’s efforts to construct a launch facility in the region. Aside from a considerable effort to create a sturdier foundation for the pad along the sandy, shifting shoreline of Boca Chica, Texas, the company’s work in the region has been rather quiet since the prospective pad’s announcement in 2014. Through a combination of tax incentives and a direct cash infusion, the state of Texas and the Rio Grande Valley region have both in some way strived to strengthen their relationships with SpaceX and solidify the iconic group’s presence in the region.
For Brownsville and Boca Chica, in particular, the latter of which has a population well under 100 individuals, SpaceX’s permanent presence would be a massive boom for the local economy by bringing an infusion of dozens or potentially hundreds of skilled, full-time positions to the quiet region.
In recent months, SpaceX has been very gradually progressing development of facilities around their potential launch site, albeit not the pad itself. These changes include a nearly complete public-private radio communications facility intended to both give college students hands-on experience and communicate with SpaceX’s Crew Dragon capsule as early as late 2018. Intriguingly, a Tesla energy installation has also been recently spotted at the facility.
Finally, a vast crane has been semi-permanently stationed on SpaceX property and had a corrugated shed build around it to protect it from the elements and SpaceX stalking fans in the region.

More than just a launch pad?
State Rep. Oliveira’s statements can be seen in full below.
“About a year ago, SpaceX came to me with their concept of a new, larger, expanded plan for Boca Chica Beach,” Oliveira said. “The concept went well beyond conducting launches, and would require new commitments for construction, investment and jobs to support the new operations.”
“We looked at the original plan for the launch site, and the chain of work that would be done inside and outside on the rockets that would take off from Boca Chica. The concept SpaceX is examining would bring a lot of that work to Boca Chica, going well beyond the original plan.”
He [State Rep. René Oliveira, D-Brownsville] declined to reveal the details of the new concept for Boca Chica, saying it’s up to SpaceX to detail its plans and associated costs when it makes a request to CCSDC to apply for funding.
The timing of SpaceX concept, reportedly presented to Oliveira in late 2016 or early 2017, strongly indicate that the rocket company is considering a considerable expansion of their aspirations for the South Texas facilities under construction. Partly based on Oliveira’s suggestion that SpaceX and Brownsville “looked at…the chain of work” necessary for rockets to launch Boca Chica, the most obvious conclusion available is that SpaceX is thinking about developing Boca Chica into a veritable rocket city.

A major problem facing SpaceX’s Mars rocket (BFR) program is dealing with the vehicle’s sheer size, 9m (30 feet) in diameter and at least as tall as Falcon 9. This size would make transporting the vehicle cross-country by road all but impossible, potentially forcing the company to abandon a bulwark of their current Falcon manufacturing strategy. The most obvious solution, as discussed briefly by CEO Elon Musk and President Gwynne Shotwell, would be to build a rocket factory where the launch pad is located. Boca Chica is thus almost certainly a prime location under SpaceX’s consideration for both the launch complex and factory needed to build and operate BFR. And this argument has been strengthened in recent months by statements from both executives hinting that prototype BFR spaceship (BFS) tests could begin in South Texas as soon as early 2019.
To say that the creation of such a manufacturing and launch infrastructure would transform the region would be an understatement. The sheer shock value of a small city being able to lay claim to the only private orbital launch complex in the US would be valuable in its own right, not to mention the distinct possibility that such a facility might one day launch the first humans to Mars. If the educated speculation above is, in fact, the truth of the matter, SpaceX can be expected to begin earnestly petitioning the local and state governments for additional public funds to partially support the major undertaking. Most importantly, the company would almost certainly need to procure an updated or wholly new environmental impact assessment from the FAA before being allowed to begin construction beyond the scope of the original 2014 grant.

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.
