Tesla partner Panasonic shares details of Gigafactory Nevada’s major expansion
It appears that Tesla’s battery partner, Panasonic, is preparing for a massive ramp in Gigafactory Nevada, with an executive stating that the Japanese firm will be rolling out a major expansion of its operations on the site. These include the installation of new equipment and the hiring of more workers, which would allow Giga Nevada to produce battery cells at higher rates than before.
Panasonic’s expansion was recently confirmed by Carl Walton, vice president of production engineering and facilities for Panasonic Energy of North America, who shared the updates in a conversation with the Reno Gazette-Journal. According to Walton, some of the expansion should take place within the next few months, and it will likely continue all the way to next year.
“There’s some construction work that needs to take place over the next couple of months. Then early next year, we’ll be installing new equipment with production starting shortly after that,” he said.
The additional capacity will be coming from a 14th battery production line that Panasonic will be adding to Giga Nevada. Walton declined to give the exact number of GWh that the planned expansion will add to the facility’s capacity, though he noted that Panasonic expects the facility’s capacity to increase by about 10% with the upgrades in place. It should be noted that currently, Gigafactory Nevada has a capacity of about 35 GWh per year.
Walton further noted that with the expansion in place, Panasonic will be hiring more employees for Giga Nevada. That being said, the executive noted that the planned hiring ramp will only include about 100 new positions, hinting at the possibility of the 14th line being heavily automated. “The expansion will increase our staffing by about 100 positions. We’re excited to continue our investment in the Northern Nevada community and our people here,” Walton stated.
While speaking with the Gazette-Journal, Walton added that the expansion plans for the Tesla site will not be limited to the new battery cell production line, since existing lines will also be receiving significant upgrades. These upgrades, the exec explained, are necessary to accommodate a new generation of battery cells. “That work is starting now and we’ve already started to convert current equipment to be able to make those batteries for us,” Walton remarked.
Interestingly enough, the Panasonic executive provided some details about the next-generation battery cells that will be produced at Gigafactory Nevada. According to Walton, Panasonic’s latest battery improves energy density by 5% compared to its previous cells. The company also claimed that its new cells are 1.4x denser than competing iron phosphate batteries, making them the world’s highest energy density batteries. These improvements are but a step, however, as Panasonic is reportedly looking to increase the energy density of its battery cells by 20%.
Panasonic’s confirmation of its planned expansion in Gigafactory Nevada highlights the Japanese firm’s strong working relationship with Tesla. Last year, a report from the Nikkei Asian Review, which cited very little sources, alleged that Panasonic was freezing its expansion plans in Giga Nevada. Panasonic Chief Executive Officer Kazuhiro Tsuga also commented on Tesla CEO Elon Musk’s “unpredictable” behavior on Twitter. Musk, for his part, noted that Panasonic has been the reason behind Giga Nevada’s battery supply constraints.
With the recent statements from Walton, however, it appears that both companies now stand on much firmer ground. Panasonic’s expansion of its Gigafactory Nevada operations seems to be a strong strategy this year, after all, especially since its battery business in the Tesla facility has proven profitable even from January to March 2020, a time that is marred by the start of the pandemic. And with electric cars becoming more popular, the Japanese firm will likely have its hands full trying to meet the battery demand for Tesla’s electric vehicles.
Tesla CEO Elon Musk posted a photo of himself standing with the Optimus production team inside Tesla’s Fremont factory, arms crossed amid workers in hard hats and safety vests. The image captures a pivotal industrial shift: the same facility space once dedicated to building Tesla’s flagship Model S sedan and Model X SUV is now home to the company’s humanoid robot manufacturing line.

Tesla’s Fremont Factory, acquired in 2010 from the former NUMMI joint venture between Toyota and GM, has been the company’s original U.S. manufacturing hub since Model S production began in 2012.
The Model X followed soon thereafter. These premium vehicles offered lower annual volumes, recently around 30,000 combined, compared to the high-volume Model 3 and Model Y lines that continue around the site. Over their combined run, the S and X accounted for roughly 610,000 units.
In late January 2026, during Tesla’s Q4 2025 earnings call, Elon Musk announced the end of Model S and Model X production in Q2 2026. The final vehicles rolled off the line in early May. Rather than retooling for another vehicle, Tesla chose to convert the dedicated S/X assembly area into a dedicated Optimus Gen 3 production line.
Model 3 and Y manufacturing remains unaffected. Tesla’s official Fremont Factory page now lists Optimus alongside the 3 and Y as core products.
The conversion was executed with remarkable speed. After production stopped, crews dismantled the existing vehicle line and installed entirely new modular equipment—including lines sourced from Germany and dozens of sub-lines for actuators, batteries, and other components—in roughly four months.
Musk described the timeline as “insanely fast,” noting it would be unprecedented for any other manufacturer. Initial Optimus output is expected to ramp slowly due to the robot’s roughly 10,000 unique parts and the brand-new production processes involved. The Fremont line targets an eventual capacity of 1 million Optimus units per year.
Tesla isn’t joking about building Optimus at an industrial scale: Here we go
Optimus Development Timeline
- August 19, 2021: Optimus (then called Tesla Bot) formally announced at Tesla’s first AI Day. A concept video showed a person in a suit demonstrating the vision for a general-purpose humanoid capable of dangerous, repetitive, or boring tasks using the same AI architecture as Full Self-Driving.
- 2022: Early prototypes displayed. At the second AI Day in September, semi-functional units demonstrated walking across a stage and basic arm movements
- 2023: September videos showed improved capabilities, including sorting colored blocks, precise limb awareness, and holding a Yoda pose.
- 2024-early 2025: Factory integration videos showed Optimus navigating workspaces and handling objects like battery cells.
- January 2026: Gen 3 mass-production activities began at Fremont, with reports of over 1,000 Gen 3 units already operating inside the factory for real-world learning and AI training
- April 2026: Musk confirms Optimus production on converted Fremont line would begin in late July or August 2026. The Gen 3 reveal, originally eyed for Q1, was pushed closer to production start. A second, much larger Optimus factory at Giga Texas is under construction, with volume production targeted for Summer 2027 and long-term capacity of 10 million units annually
- July 1, 2026: Musk’s on-site visit and team photo confirm the Optimus line is operational and the transition is actively progressing
Tesla positions Optimus as potentially its largest project ever, leveraging vertical integration, AI expertise, and car-like manufacturing know-how to scale humanoid robots first for its own factories and later for broader industrial and consumer use.
The Fremont conversion serves as a critical proving ground for this ambitious new chapter in Tesla’s already-rich history.
Investor's Corner
Tesla gets its latest short from Michael Burry: ‘Happy it jumped back to this level’
Tesla short seller Michael Burry, the subject of the film “The Big Short,” where he was portrayed by Steve Carell, has revealed he has opened a new bet against the stock.
In a new update to his Substack newsletter in a post titled “Trading Post June 30, 2026,” Burry revealed a new set of bets against Tesla, Caterpillar, NVIDIA, Applied Materials Inc., and the iShares Semiconductor ETF.
In regard to Tesla, Burry wrote:
“And finally I shorted Tesla at 416.22. Happy it jumped back to this level.”
This means Burry likely opened his new short position after the company’s recent rally on Wall Street, which saw Tesla shares sink in mid-May, only to recover to well over the $400 mark. Currently, shares trade at around $427.
The company saw a big Tuesday as shares climbed considerably, over 10 percent. The size of the Tesla short was not provided, nor did Burry give any information on the position’s structure, the number of shares, dollar value, or whether options were used in the short.
The Tesla and SpaceX merger everyone is talking about is quietly building
Over the years, Burry has been one of the more vocal critics of Tesla, calling its share price “media inflated,” and saying it was “ridiculously overvalued” as recently as December.
The company has largely transitioned away from being known as an automotive company and instead is much more widely regarded as an AI play, mostly due to its Full Self-Driving efforts, Optimus robot development, and data collection related to both.
This has not pulled those skeptics away from being vocal about their distaste for how Tesla is valued, but there’s no denying that the company is a global force in many things, including sustainable energy, automotive, and AI.
Wedbush Securities is initiating stock coverage on SpaceX (NASDAQ: SPCX), marking the first comments on the company since it went public several weeks ago. Wedbush and its analyst handling coverage, Dan Ives, are widely bullish on fellow Musk company Tesla (NASDAQ: TSLA).
Ives wrote his first note initiating coverage of SpaceX shares on Wednesday with a $190 price target and an ‘Outperform’ rating. The firm believes the company is well positioned off of its IPO because of its wide array of projects, including AI compute power and infrastructure, connectivity projects, and launches.
“We view SpaceX as one of the most differentiated assets within the tech market with a strong footprint across its three core markets, with Starlink driving success with connectivity,” Ives wrote, “Starship launches leading to a demand flywheel and increasing deal flow for its Colossus clusters.”

Wedbush leans heavily on Starlink, which they say is the “profitability driver given the strength of its recurring revenue base of ~12 million subscribers as of June 5th.” Ives believes Starlink is still in the “early innings” of penetrating the global telecommunications and broadband market, as it only holds less than a 1 percent share. However, this number is sure to increase over time.
It also highlights the importance of Starship, which it says is an “essential layer” of SpaceX’s overall success. SpaceX developing and displaying the ability to reuse rockets is a major cost and reliability advantage “as it reduces the necessary hardware launch costs while generating a feedback loop for future flights to improve their launch flight rate without accelerating capex spend.”
Finally, SpaceX’s recent AI/Compute projects are also very elementary, Ives writes. It is worth mentioning Wedbush said its $190 price target is derived from a valuation forecast that sees the company yielding roughly $2.48 trillion of implied enterprise value.
There are also some factors that Wedbush did not take into account with its initial coverage. The firm wrote in the note:
“We note that there is optional value coming from Starship’s accelerating scale towards sub-$200/kg unit economics, orbital data centers, and enterprise AI monetization as these factors could drive meaningful upside but these face major hurdles, so we do not take that into account with our valuation.”
SpaceX shares are down just over 2 percent today, trading at around $167 at the time of publication.
