Tesla files to build EV batteries on new production lines at Fremont Factory
Tesla (NASDAQ: TSLA) has filed to build a new battery manufacturing equipment line at the Fremont Factory in Northern California. The factory, which Tesla purchased in 2010, is the only in the company’s lineup to produce all four models. It has not been known as a battery cell or pack manufacturing plant, as the company’s Gigafactory in Sparks, Nevada, produces those EV components. However, the filings indicate Tesla may be looking to slightly expand its cell manufacturing efforts with new production lines at Fremont.
Filed and signed by Tesla on August 30, the permit is labeled as “Tesla F21-0391-A – CTA Battery B-Build.” Tesla gives the following description of the project:
“NEW BATTERY MANUFACTURING EQUIPMENT LINE ON 2ND FLOOR OF MAIN ASSEMBLY BUILDING. THIS PERMIT APPLICATION RELATES TO THE MODULE PORTION OF THE LINE.”
The project is valued at $1.5 million, according to documents seen by Teslarati.

Additionally, another application reveals a $1.3 million project that includes the installation of a new maintenance office, a storage area, production cells with equipment for hood, fender, and trunk lids, and offline cell manufacturing equipment. This project is listed to be on the first floor of the assembly building.
Interestingly, the Fremont Factory has been one of Tesla’s more spacially-confined facilities. Earlier this year, during a visit from Morgan Stanley analysts, including Adam Jonas, the firm noted the Fremont Factory was incredibly tight in terms of storage capacity and room in general. Despite running at a capacity of 20 percent above what has been considered its maximum. “The plant was never designed to produce 450k units (at its peak produced ~300k units before Tesla took it over from Toyota), which was immediately apparent at the tour, ” Jonas wrote in his note describing the visit. “Tesla does not shy away from the fact the plant is inefficiently designed with four assembly buildings, one of which is a tent that cars are assembled in,” referring to GA 4.5, which was made permanent last year.
Just two weeks prior to Morgan Stanley’s visit to Fremont, CEO Elon Musk stated Tesla was considering expanding Fremont “significantly.” While many of us just thought this likely meant an expansion of vehicle production alone, Musk may have been hinting toward an expansion of the manufacturing process altogether.
Tesla battery manufacturing efforts
Tesla has held battery supply deals with Panasonic, CATL, and LG Chem, but has also started building its own cells in-house. In 2020, Tesla unveiled its 4680 battery cell, which has already been prototype-tested by Panasonic. Tesla has been building the cell at the Kato Rd. facility just a few blocks away from Fremont’s front doors. However, the automaker has not scaled this cell to mass production as of yet, and Tesla could always use more battery cells.
With the 4680 cell not quite reaching mass production volumes yet, an order log that grows with what seems to be every minute, and a production volume that just simply has not caught up to Tesla’s demand, it would make sense to expand in-house battery manufacturing efforts as supplementary support.
“I think we’ve said this now for many years. I know has proven true. Tesla does not have a demand problem, we have a production problem. And we’ve almost always had it’s a very rare exception it’s always been a production problem,” Musk said after Q2. “I think that will remain the case.”
Rearranging at the Fremont Factory
Over the past month or so, Tesla has filed to make many significant changes at the Fremont Factory. After we reported on the construction efforts that are seemingly underway, Tesla has also been filing several applications with the City of Fremont for equipment repositioning, as well as the construction of new foundations and manufacturing equipment. Even things as simple as light poles are being repositioned to make way for potential new manufacturing buildings.

Tesla has also started relocating Model S and X production equipment to other portions of the factory. “GASX,” which we can assume is “General Assembly Model S and X,” has had a hoist relocated, according to filings. Tesla has also filed to install production tools and other associated Model S and Model X manufacturing utilities in the factory. This does not necessarily imply that production lines for the two vehicles will be expanding, especially considering the vehicles make up an extremely small portion of Tesla’s overall sales. However, these manufacturing lines may be shifting to other locations at Fremont to make way for the perhaps imminent installation of cell manufacturing lines at Fremont.

Elon Musk gives his most telling Tesla-SpaceX merger conversation yet
Elon Musk hinted a Tesla-SpaceX merger could be coming, and Wall Street is taking notice.
Elon Musk gave his clearest signal yet that Tesla and SpaceX could eventually combine, telling the All-In Summit in Los Angeles that the two companies’ deepening collaboration makes the question worth asking. Sawyer Merritt first surfaced the highlight on X Tuesday.
Asked directly why Tesla and SpaceX remain separate given how closely they already work together, Musk told hosts at the summit: “Great question there. With all this collaboration, on so many levels, who can imagine what action one might take when there’s so much close collaboration in so many areas.” SpaceX President Gwynne Shotwell, who joined Musk on stage, added that SpaceX personnel have already moved into xAI to fill leadership and engineering gaps, saying the businesses are integrating “faster than I thought,” though “not fully integrated yet,”
The comments landed on top of merger speculation that has been building on Wall Street for months. JPMorgan has called a tie-up “strategically coherent on paper,” pointing to overlapping ambitions in AI, robotics, energy, transportation and space. Jefferies went further, estimating Musk could retain roughly 55.3 percent voting control in a deal structured without a premium, a scenario that would still leave room for Tesla shareholders to come out ahead. On Kalshi, traders now put the odds of a merger before 2028 at 66 percent.
Tesla’s stake in SpaceX, still under one percent, traces back to its earlier investment in xAI, which converted to SpaceX equity after SpaceX absorbed the AI company. The two are also jointly building Terafab, a chip facility in Austin meant to serve both Tesla’s AI computing needs and SpaceX’s satellite ambitions. Wedbush analyst Dan Ives has stood by a 2027 merger timeline for months, and Cathie Wood’s ARK Invest recently floated a similar case, an idea Musk pushed back on directly at the time.

The timing adds another layer. Tesla has scheduled an October 1 unveiling for its next generation Roadster at a venue near SpaceX’s McGregor, Texas test site, using the phrase “Go for launch” in its promotional material. Both stocks dipped roughly 2 percent Monday before recovering slightly in premarket trading Tuesday, with SpaceX shares up about 0.4 percent and Tesla essentially flat.
Musk stopped short of confirming anything is in motion. But unlike his past denials of a corporate restructuring, this response didn’t rule one out, and it came with Shotwell sitting next to him describing an integration that’s already underway.

Tesla Cybercabs narrowly miss deadly Amazon cargo plane crash
An Amazon cargo plane crash near Miami’s airport stopped feet from dozens of Tesla Cybercabs.
An Amazon Prime Air Boeing 767 cargo jet overran the runway at Miami International Airport on Sunday afternoon, killing five people and injuring five more. The jet, operated by North Carolina based carrier 21 Air as Flight 7598, touched down around 2 p.m. after arriving from San Juan, Puerto Rico, then crossed the airport perimeter, plowed across NW 67th Avenue and struck multiple vehicles before catching fire, according to the Associated Press.
Photos and video from the scene show the aircraft’s nose stopped within meters of a fenced staging lot holding dozens of gold painted Tesla Cybercabs, the steering wheel free robotaxi Tesla began putting on public roads in Austin last week. Miami-Dade Fire Rescue has confirmed the plane struck “multiple vehicles” but has not said whether any Cybercabs were among them, and neither Tesla nor airport officials have addressed the fleet directly.
The Cybercabs had not yet entered commercial service in Miami. Tesla’s existing Robotaxi operation there runs on modified Model Y vehicles and has been unsupervised since Ashok Elluswamy confirmed the detail on X in July.

Elon Musk offered the briefest of reactions. Replying to a Zero Hedge post about the Cybercabs sitting so close to the wreckage, he wrote a single word: “Weird.” He has not commented further, and Tesla has not issued a statement.
The timing puts Tesla’s newest vehicle near an unrelated but highly visible tragedy just days after its Austin debut, a launch that had already drawn scrutiny from federal regulators. The National Highway Traffic Safety Administration opened an audit how Tesla certified the Cybercab as compliant with federal vehicle safety standards, a process Teslarati covered after the vehicle’s September 3 launch event. That inquiry concerns the car’s lack of a steering wheel and pedals, not the Miami crash.
Investigators from the FAA and NTSB are focused on the plane, not the parking lot beside it. Flight data reviewed by outlets including Simple Flying show the 767 touched down around 170 knots, well above the 135 to 140 knot range typical for the aircraft, though investigators have not determined a cause. Amazon said it is working with authorities and that its priority is the safety of everyone affected.
Whether any Cybercabs were damaged, and what Tesla plans for the fleet parked near one of the country’s busiest airports, remain open questions.

Tesla Cybercab is coming to Asia this month as US service officially begins
Tesla Asia says Cybercab will be on display in Hong Kong, Tokyo, Beijing and Shanghai this month.
Tesla’s Cybercab is heading to Asia. The official Tesla Asia account posted on X Thursday, inviting Cybercab fans to “Come experience the future of autonomy in Hong Kong, Tokyo, Beijing & Shanghai.” The post went up within hours of Tesla’s own Cybercab milestone in Texas, where the company said Thursday it had begun offering rides in across Austin.
Exact dates and venues for the Asia tour haven’t been released yet, though Tesla Hong Kong replied to the announcement with “Cybercab will be on display in Hong Kong soon,” while Tesla Japan’s response pointed fans to a sign up page for updates. Neither post mentions test rides or a service area, and nothing so far suggests Tesla is launching Robotaxi operations in any of the four cities. Based on how Tesla has run past Cybercab tours, in Europe in late 2024 and at US shopping centers that same December, the Asia stops are almost certainly static displays at Tesla stores or public venues as a means to stimulate buzz for its future driverless ride-hailing service in the big cities.

The timing lines up with Tesla’s only prior Cybercab appearance in the region, a booth at the China International Import Expo in Shanghai last November, which Teslarati covered at the time. At that event, Tesla’s regional general manager for Shanghai framed the car as evidence of the company’s broader mission, a message Tesla has since formalized in its Master Plan Part IV, which states that “autonomous vehicles have the capacity to dramatically improve the affordability, availability and safety of transportation while reducing pollution, particularly in our increasingly dense global cities.” The same document is where Tesla lays out its “sustainable abundance” framing for Cybercab and Optimus alike, describing the two as the hardware behind an AI driven push to cut the cost of transportation and labor at scale.
Whether Cybercab actually operates as a robotaxi anywhere in Asia remains an open question, considering China has already pushed an autonomous ride-hailing market that’s run on homegrown players like Baidu’s Apollo Go and Pony AI. For now, the four city tour reads as a marketing push timed to Austin’s momentum.
