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.

California snubs Tesla in its newly passed EV incentive that favors Rivian and Lucid
California passed a $135 million EV incentive that rewards Rivian and Lucid while sidelining Tesla
California just drew a line in the EV incentive sand to put Tesla on the wrong side of it. The state recently passed a $135 million program offering first-time electric vehicle buyers a direct incentive with no application required, but the rules were written in a way that leaves Tesla at a structural disadvantage compared to Rivian and Lucid.
The program caps eligible vehicles at $50,000 for new EVs and $25,000 for used ones. That pricing threshold rules out a significant portion of Tesla’s lineup, though some lower-priced Model 3 and Model Y configurations would still qualify. California-based automakers are exempt from the price cap entirely, regardless of what their vehicles cost. Rivian, headquartered in Irvine, and Lucid, based in the San Francisco Bay Area, both benefit from that exemption. Rivian’s R2 starts at roughly $45,000 but has versions above the cap. Lucid’s Air and Gravity start at $70,990 and $79,990 respectively, well above any threshold a non-California company would face.
California hits Tesla Cybercab and Robotaxi driverless cars with new law
Tesla built its reputation and a significant portion of its early market share in California, where EV adoption has consistently led the nation. The company operates its original factory in Fremont, California, and the state was home to Tesla’s headquarters for most of its existence. That changed in 2021 when Tesla moved its corporate headquarters to Austin, Texas. Since then, the relationship between the company and California Governor Gavin Newsom has been openly adversarial, with Musk and Newsom trading public criticism on multiple occasions.
California’s EV incentive landscape has shifted repeatedly in recent years, and Tesla has previously lost eligibility for state-level programs as its vehicles exceeded income-adjusted price thresholds. The federal $7,500 EV tax credit, which Tesla models have qualified for and lost depending on policy cycles, is no longer available after it expired without renewal, making state-level programs more meaningful to buyers than they have been in years.
The practical impact for buyers is more nuanced than the headline suggests. California residents purchasing a Tesla under $50,000 for the first time can still access the incentive. But the exemption written for California-based manufacturers is a structural advantage that rewards where a company plants its headquarters flag rather than where it builds its products, and Tesla moved that flag to Texas.

SpaceX’s newest logo confirms everything about what it’s become
SpaceX officially absorbed xAI under the SpaceXAI brand, completing the largest private merger in history.
SpaceX made its corporate transformation official in May 2026 when Elon Musk posted on X that xAI would cease to exist as a standalone company. “xAI will be dissolved as a separate company, so it will just be SpaceXAI, the AI products from SpaceX,” he wrote.
A new SpaceXAI logo was announced today, visually embedding the xAI letters inside the SpaceX identity, which can be seen as a deliberate design choice that signals the merger is not a partnership but a full absorption and XAi a core function of the same company. The same way Starlink is not a separate brand but a SpaceX product. The announcement closed the loop on a process that began February 2, 2026, when SpaceX acquired xAI in the largest private merger in history, valued at $1.25 trillion. SpaceX at $1 trillion and xAI at $250 billion.

The reason SpaceX bought xAI was stated plainly by Musk at the time of the deal: to build orbital data centers. SpaceX had simultaneously filed with the FCC to launch up to one million satellites designed to function as AI compute nodes in low Earth orbit, escaping what Musk described as the energy constraints limiting AI development on Earth.
xAI provided the AI software stack, with Grok, the X platform, and the Colossus supercomputer infrastructure in Memphis with over 220,000 NVIDIA GPUs, while SpaceX provided the rockets, Starlink, and the capital base to fund it. The two companies needed each other. xAI was burning $2.5 billion in losses on $250 million in revenue. SpaceX was generating an estimated $8 billion in profit on $15 billion in revenue and needed an AI narrative to command the valuation it was targeting for its IPO.
What SpaceX has done, regardless of how the orbital AI vision ultimately plays out, is walk into a public market as something no company has been before: a rocket manufacturer, satellite internet provider, AI software company, social media platform, and supercomputer operator under one ticker. Whether that combination is worth $2 trillion depends entirely on which of those businesses you believe in most.

Tesla challenges startups to score a gig inside its most advanced European factory
Tesla is challenging startups to bring their best battery tech directly to Gigafactory Berlin.
Tesla has issued an open challenge to startups across Europe, inviting them to bring their best battery technology directly to the floor of Gigafactory Berlin. The program, called the JUNI x Tesla Battery Cell Giga Challenge, opened applications this month with a deadline of July 24, 2026, and is targeting startups with solutions that can make battery cell manufacturing faster, cheaper, safer, and more scalable at an industrial level.
The timing of the challenge is directly tied to Tesla’s most aggressive European battery investment yet. On May 12, 2026, Giga Berlin plant manager André Thierig announced a $250 million investment to scale the factory’s annual 4680 cell production capacity from 8 GWh to 18 GWh, more than doubling the previous target set just months earlier in December 2025. Thierig confirmed the expansion on X, saying the investment “will enable 18 GWh of annual 4680 cell production and create more than 1,500 new jobs.” Combined with a previously announced battery investment at the Grunheide site now approaches $1.2 billion.
Today, we announced a $ 250m investment for our Giga Berlin Cell factory. This will enable 18GWh of annual 4680 cell production and create more than 1500 new jobs. Good news during challenging times for the German industry. pic.twitter.com/ou4SWMfWh9

The challenge is looking specifically for startups with proven solutions across five categories: materials, equipment, operations, automation, and artificial intelligence. Applications are screened directly by Tesla’s cell manufacturing team in Grunheide, and the strongest submissions move through technical discussions, a pitch day in front of Tesla stakeholders, and potentially a paid pilot project with the cell team. Tesla is not looking for ideas at concept stage. The program requires applicants to demonstrate working prototypes, test data, or prior pilots before being considered.
The historical context matters here. Elon Musk first announced plans for what he called the world’s largest battery cell production facility alongside the Giga Berlin car factory back in 2020, targeting up to 250 GWh of annual capacity. Those plans were shelved in 2022 when Tesla shifted its battery investment focus to the United States to take advantage of Inflation Reduction Act incentives. The revival of cell production at Giga Berlin, now backed by over $1 billion in committed capital, represents a return to an ambition that was set aside for three years. As Teslarati has reported, the 4680 format is central to Tesla’s long-term cost reduction strategy across vehicles, energy storage, including the Tesla Semi and Cybercab.
By opening the challenge to outside startups, Tesla is acknowledging that reaching 18 GWh at Grunheide will require technology it does not currently have in-house, and it is willing to pay for the right solutions. For a startup in the battery supply chain, a paid pilot with Tesla’s European cell team is as close to a direct commercial path as the industry offers.
