EXCLUSIVE: Tesla Cybertruck battery packs to be built at Fremont Factory
Tesla plans to start building battery packs for the upcoming Cybertruck on a new cell manufacturing line in the Fremont factory, people with knowledge of the project told Teslarati.
In August, we reported that Tesla had filed to build a new battery manufacturing equipment line on the second floor of the Fremont factory. This filing, which was submitted to the City of Fremont on August 30, relates to the module portion of the line, Tesla said.
Tesla described the project as “CTA Battery B-Build,” the filing shows.

Tesla is ultimately planning to build the Cybertruck in Austin at Gigafactory Texas. However, battery cells and cell pack manufacturing are not yet ready to take off at the new Tesla plant, which is located just outside Austin. Tesla applied to build a battery and cathode manufacturing building at Gigafactory Texas earlier this year, and while the project has been started, it likely will not be ready for the Cybertruck’s projected launch in mid-2023.
With an extensive order log that features over 1 million total reservations, Tesla is preparing for Cybertruck manufacturing by building the battery packs at a plant that is already operational. The Fremont facility, the only Tesla plant manufacturing all four vehicles the company builds, was ultimately chosen for the task of kicking off Cybertruck pack manufacturing, Teslarati confirmed with sources familiar with the matter.
Cybertruck Battery Pack Manufacturing will start in Fremont
Sources familiar with the matter told Teslarati the second-floor manufacturing line that Tesla filed to build in August will manufacture the Cybertruck packs. Tesla will take the 4680 battery cells produced at the Kato Road facility or another previously utilized cell design manufactured at Gigafactory Nevada and put them into modules and packs that are manufactured on the new Fremont battery line.
Currently, the line is being completed by construction crews on site, who are making daily progress. Additionally, Tesla engineers are installing automation equipment to produce the Cybertruck battery packs.
Tesla did not immediately respond to our request for comment.
Kicking Cybertruck Module Production into “Plaid Mode”
Tesla is also working hard to kick off Cybertruck pack production as time is extremely limited. Tesla has a series of vehicles, referred to as “carriers,” which transport batteries throughout the factory. The company recently ordered around 300 new carriers for the factory as cell and battery pack manufacturing is set to ramp drastically.
The sources also said the Cybertruck battery pack line is currently being tested with Tesla’s automation equipment. Tesla is working to ramp the line quickly as Cybertruck vehicle manufacturing is planned for next year at Gigafactory Texas.
2023: The Year of the Tesla Cybertruck?
Tesla is set to build the Cybertruck at Gigafactory Texas. After unveiling the all-electric pickup in 2019, Tesla has delayed initial production on several occasions due to supply chain issues and other challenges.
“In 2022, supply chain will continue to be the fundamental limiter of output across all factories,” Musk said during Tesla’s Q4 and 2021 Full Year Earnings Call in January. So the chip shortage, while better than last year, is still an issue. And, yeah, so that’s — there are multiple supply chain challenges.”
Musk went on to say that the challenges would delay the launch of any new products in 2022. “We will, however, do a lot of engineering and tooling, what not to create those vehicles: Cybertruck, Semi, Roadster, Optimus, and be ready to bring those to production hopefully next year. That is most likely.”
Although Tesla is planning to begin deliveries of the Semi on December 1, all other projects have been effectively delayed until next year, but preparation to launch those projects is evidently a priority within the factories.
4680 cells are not constrained but are they going into the Cybertruck?
Tesla’s Vice President of Powertrain Drew Baglino detailed earlier this year that the company was not constrained in terms of 4680 battery cell availability.
“So throughout 2021, we focused on growing cell supply alongside our in-house 4680 effort to provide us flexibility and insurance as we attempt to grow as fast as possible,” Baglino said on the Q4 and Full Year 2021 Earnings Call in January. “4680 cells are not a constraint to our 2022 volume plans based on the information we have.”
What Baglino said next on the call likely indicates what Tesla was preparing the Cybertruck for: pack manufacturing at Fremont, shipping the packs to Texas, and then installing them into vehicles:
“But we are making meaningful progress of the ramp curve in Kato. We’re building 4680 structural packs every day, which are being assembled into vehicles in Texas. I was driving one yesterday and the day before. And we believe our first 4680 vehicles will be delivered this quarter.”
The Kato Road facility has supported Tesla’s 4680 cell needs thus far. The 4680 packs were installed on some Gigafactory Texas-built Model Ys, and were reviewed by Munro Live earlier this year. Fremont will likely support Cybertruck pack manufacturing for some time, utilizing cells from Kato Road and from suppliers like Panasonic when they ultimately being manufacturing the battery for Tesla.
As Cybertruck manufacturing ramps up into late 2023, 2024, and beyond, packs will then be at Fremont and Gigafactory Texas, which would likely entirely support Cybertruck production.

Elon Musk’s Boring Company lands a new Middle East deal, and Nashville is about to get faster
The Boring Company signs Abu Dhabi tunnel agreement while adding more Prufrock machines in Nashville.
The Boring Company has signed an agreement with Abu Dhabi to study underground transport and utility tunnels across the emirate, adding a second UAE city to its pipeline as it prepares to also scale up tunneling back home in Nashville.
The deal was signed Thursday at the Liveability and Investment Exhibition (LIVEX 2026) by Boring Company President Steve Davis and Maysarah Mahmoud Salim Eid, director general of the Abu Dhabi Projects and Infrastructure Centre (ADPIC), according to the Abu Dhabi Media Office. Mohamed Ali Al Shorafa, chairman of the emirate’s Department of Municipalities and Transport, attended the signing.
Under the agreement, the two sides will assess feasibility, delivery and operating models for tunnels that could carry passengers or utilities. They will also look at Abu Dhabi’s potential as a regional hub for tunneling work. The current phase is exploratory, and no construction commitment or project budget has been announced.
“Abu Dhabi provides an ideal environment to explore the next generation of underground infrastructure solutions, supported by its ambitious growth vision and strong commitment to advanced technologies,”
Davis said. He added that the company wants to assess how tunnels can “expand urban capacity more efficiently, and enable better use of available space.”
The timing lines up with the money, considering last month, The Boring Company closed a $3 billion Series D led by the UAE and affiliated investors, valuing the company at $23 billion, as Teslarati reported. That round came with a commitment to build more than 150 kilometers of tunnel across the UAE, separate from the Dubai Loop pilot already under contract with Dubai’s Roads and Transport Authority. That pilot covers 6.4 kilometers and four stations linking DIFC and Dubai Mall at a cost of about $154 million.
Back home, The Boring Company projects in Nashville are also scaling up, with the company telling local NewsChannel 5 that a third Prufrock machine could start digging the Music City Loop in late October. A fourth is also targeted before the end of the year. Two machines are already mining Nashville limestone at the same time, and work is underway on a new launch site for the third.
The company said it has made more than 300 design and performance upgrades to its original Nashville machine. It is also working with property owners on more than 40 planned stations, with approvals in place for a future Nashville International Airport connection, a downtown station near the Music City Center, and stops at residential towers and the JW Marriott.
Construction on the Music City Loop began the same evening Tennessee and federal regulators approved the project’s lease in February, and the company targeted its first operational segment for late 2026. Back in Las Vegas, The Boring Company has said it plans to double its Vegas Loop station count by year’s end.

SpaceX brings four astronauts home after 8 months in space, and the return was flawless
SpaceX Crew Dragon Freedom returned four Crew-12 astronauts home after 237 days aboard the station.
Four Crew-12 members are back on Earth after 237 days at the International Space Station. SpaceX’s Crew Dragon Freedom splashed down in the Pacific Ocean about 50 miles west of Los Angeles at 11:34 a.m. ET on Thursday.
NASA astronauts Jessica Meir and Jack Hathaway, ESA astronaut Sophie Adenot, and Roscosmos cosmonaut Andrey Fedyaev landed one day after undocking from the station’s Harmony module at 8:05 a.m. ET on Wednesday. NASA confirmed the splashdown minutes later. SpaceX had flagged the 27.5 hour trip home on X while Dragon was still firing its departure burns away from the station.
The descent ran on schedule when Freedom started a nine minute deorbit burn at 10:46 a.m. ET, then hit the thicker atmosphere about 36 minutes later at nearly five miles per second. Chutes deployed at around 18,000 feet, and four main parachutes brought the capsule down to roughly 15 mph at splashdown.
SpaceX fast boats secured Dragon before the recovery ship Shannon hoisted it onto the deck with the crew still inside. Flight surgeons on board ran initial medical checks. All four crew members will be flown ashore by helicopter and then head to NASA’s Johnson Space Center in Houston for rehabilitation.

Crew-12 launched on February 13 from Space Launch Complex 40 at Cape Canaveral, a flight that also marked the first Falcon 9 booster landing at SpaceX’s new LZ-40 pad. Over the mission, the crew completed 3,792 orbits, covered nearly 101 million miles, and carried out four spacewalks to maintain and upgrade the station.
Meir now has 440 cumulative days in space, which places her in NASA’s top 10. This was the first spaceflight for Hathaway and for Adenot, a French Air Force colonel and former helicopter pilot. Fedyaev, who spent 186 days in orbit on Crew-6 in 2023, has now flown two long duration Dragon missions.
The return closes out a busy stretch of Dragon traffic. Crew-13 arrived on October 1 aboard Crew Dragon Grace, which docked just 7 hours and 55 minutes after liftoff, the fastest launch to docking of any U.S. spacecraft in ISS history. Commander Jessica Watkins, pilot Luke Delaney, Canadian Space Agency astronaut Joshua Kutryk, and cosmonaut Sergey Teteryatnikov remain aboard alongside the three person Soyuz MS-29 crew.
With Crew-12 gone, the port is clear for CRS-35, a cargo Dragon carrying the final pair of ISS Roll-Out Solar Arrays. NASA is holding a post-splashdown teleconference at 1:15 p.m. ET covering both the crew’s return and the upcoming cargo launch.

Elon Musk shuts down talk of TSMC taking over Terafab
Musk says Tesla and SpaceX will build and run Terafab, with TSMC limited to renting.
Elon Musk has drawn a firm line around who will be in charge of Terafab, the giant chip factory Tesla and SpaceX are planning in Texas.
Musk replied to a post on X arguing that Taiwan Semiconductor Manufacturing Company (TSMC) would most likely end up owning and operating the plant. “No, we will build and run the fab. Let there be ZERO doubt about that,” Musk wrote. “Maybe TSMC subleases part of the Terafab if they want, but nothing more than that.”
In plain terms, a sublease means TSMC could rent a section of the complex to make chips, similar to a tenant renting one floor of an office tower. The building, the equipment decisions and the daily operation would stay with Tesla and SpaceX.
@herbertong @thejefflutz No, we will build and run the fab. Let there be ZERO doubt about that.
Maybe TSMC subleases part of the Terafab if they want, but nothing more than that.
— Elon Musk (@elonmusk) October 7, 2026
The comment shuts down speculation that started last week. On October 2, tech journalist Tim Culpan reported that TSMC was exploring ways to help run Terafab’s factories. Musk responded the next day that it was “just discussions, but something may come of it,” as Teslarati reported at the time. That left room for a scenario where the world’s largest contract chipmaker took the wheel. Musk’s latest post closes that door.
Some background helps explain why this matters. Tesla designs its own AI chips today but pays outside companies like TSMC and Samsung to manufacture them. Musk unveiled Terafab in March as a joint project between Tesla, SpaceX and xAI, arguing that existing suppliers cannot expand fast enough to meet his companies’ future demand. The goal is to produce enough chips each year to supply one terawatt of computing power, roughly 50 times what the entire global AI chip industry produces now.
Those chips are meant for Tesla’s Optimus humanoid robots, the Cybercab and Full Self-Driving computers, along with chips for SpaceX’s planned data centers in orbit. Owning the factory means Musk’s companies would not have to compete with every other chip customer for time on someone else’s production lines.
Intel is still part of the picture. The company signed on in April to help design, build and package chips for the project, and CEO Lip-Bu Tan told Bloomberg this week that Intel will keep working on Terafab despite the TSMC chatter.
The project moved from concept to construction planning over the summer. In August, SpaceX confirmed the Grimes County site about an hour from Houston, sent the county a $10 million payment under its tax abatement deal and said civil work would begin shortly. The first phase carries a $16.8 billion price tag, and total spending across all phases could reach as much as $119 billion.
TSMC chairman C.C. Wei has said a new fab typically takes two to three years to build and another one to two years to reach full output. Tesla and SpaceX have never run one, which is why TSMC’s expertise drew so much attention. Musk’s answer suggests he would rather learn that process in house than hand control of a project this central to Tesla’s robotics and autonomy plans to an outside company.
Terafab Texas will be the largest and most valuable building on Earth by far.
And it will be stunningly beautiful. https://t.co/4NweOqTL7y
