Tesla has announced that it has produced its 100 millionth 4680 battery cell across all its factories. The update came just over three months after the company announced that it had produced a total of 50 million 4680 cells.
The milestone was posted on Tesla’s official social media account on X. Tesla included an image of its 100 millionth 4680 battery being held by an Optimus Gen 2 humanoid robot in its post.

Industry watchers who have closely watched the development of Tesla’s 4680 program were quite impressed with the electric vehicle maker’s recent milestone. Tesla, after all, just announced on June 5 that it had produced its 50 millionth 4680 cell at Giga Texas.
Considering the 101 days that have elapsed since the June announcement, Tesla appears to have produced, at least on average, about 495,000 4680 cells per day. Each Cybertruck is equipped with 1,344 4680 cells, so such an average output would translate to a production capacity of about 368 Cybertrucks a day, or 2,578 per week.

This also suggests that based on the output of the 4680 battery cells, Tesla could produce 33,514 Cybertrucks per quarter, or about 134,280 units of the all-electric pickup truck per year, as estimated by Tesla battery enthusiast The Limiting Factor in a post on X.
Recent aerial footage taken of the Giga Texas complex reveals that the electric vehicle maker is hard at work ramping up the production of the Cybertruck. Despite this, recent estimates hint that Tesla is still just closing in on producing 2,000 Cybertrucks per week.
Tesla just reached 100 million 4680 cells produced! ?
The last update was on the 5th of June where they announced 50 million cells produced.
There were 101 days in that time span, which means that on average, they produced 495,000 cells/day.
In terms of Cybertrucks, that’s… https://t.co/uKppZjLrIN— The Limiting Factor (@LimitingThe) September 14, 2024
This may then suggest that for now, at least, the supply of 4680 cells is no longer the bottleneck for the Cybertruck’s production. Of course, Tesla may also be stockpiling some 4680 cells in preparation for the Cybertruck’s increase in production once the Foundation Series formally ends.
The progress of Tesla’s 4680 battery cell program has been remarkable this year. Announced in Tesla’s 2020 Battery Day event, the 4680 cell program saw notable delays, to the point where company critics were claiming that Elon Musk might give up on the whole program. Earlier this year, however, a report from China emerged stating that Tesla is finally planning on mass producing the “complete” version of the 4680 cell—which includes a dry positive and negative electrode—by the end of this year.

The Boring Company’s Prufrock-2 emerges after completing new Vegas Loop tunnel
The new tunnel measures 2.28 miles, making it the company’s longest single Vegas Loop tunnel to date.
The Boring Company announced that its Prufrock-2 tunnel boring machine (TBM) has completed another Vegas Loop tunnel in Las Vegas. The company shared the update in a post on social media platform X.
According to The Boring Company’s post, the new tunnel measures 2.28 miles, making it the company’s longest single Vegas Loop tunnel to date.
The new tunnel marks the fourth tunnel constructed near Westgate Las Vegas as the Vegas Loop network continues expanding across the city.
The Boring Company also noted that the new tunnel surpassed its previous internal record of 2.26 miles for a single Vegas Loop segment.
Construction of the tunnel involved moving roughly 68,000 cubic yards of dirt. The excavation process also used about 4.8 miles of continuous conveyor belt, powered by six motors totaling 825 horsepower.
The Boring Company’s Prufrock-series all-electric tunnel boring machines are designed to support the rapid expansion of company’s underground transportation projects, including the growing Vegas Loop network. Prufrock machines are designed for reusability, thanks in no small part to their capability to be deployed and retrieved easily through their “porposing” feature.
The Vegas Loop, specifically the Las Vegas Convention Center (LVCC) Loop segment, has already been used during major events. Most recently, the LVCC Loop supported the 2026 CONEXPO-CON/AGG construction trade show, which was held from March 3-7, 2026.
As per The Boring Company, the LVCC Loop transported roughly 82,000 passengers across the convention center campus during the event’s duration.
CONEXPO-CON/AGG is one of the largest construction trade shows in North America, drawing more than 140,000 construction professionals from 128 countries this year.
The LVCC Loop forms the initial segment of the broader Vegas Loop network, which remains under active development as The Boring Company continues building new tunnels throughout the city.

Tesla gathers Cybercab fleet in Gigafactory Texas
Images and video of the Cybercab fleet were shared by longtime Giga Texas observer Joe Tegtmeyer in posts on social media platform X.
Tesla appears to be assembling a growing number of Cybercabs at Gigafactory Texas as preparations continue for the vehicle’s mass production. Recent footage shared online has shown over 30 Cybercabs being transported by trucks or staged near testing areas at the facility.
The images and video were shared by longtime Giga Texas observer and drone operator Joe Tegtmeyer in posts on social media platform X.
Interestingly enough, Tegtmeyer noted that many of the Cybercabs being loaded onto transport trucks were still equipped with steering wheels. This suggests that the vehicles are likely testing units rather than the final driverless configuration expected for the company’s Robotaxi service.
The vehicles could potentially be headed to testing sites across the United States as Tesla prepares to expand its Robotaxi fleet.
Additional footage captured at Gigafactory Texas also showed the Cybercab’s side and rear camera washer system operating as vehicles were being loaded onto transport trucks.
The growing number of Cybercabs at Giga Texas comes amidst the company’s announcement that the first production Cybercab has been produced at the facility. Full Cybercab production is expected to begin in April.
The vehicle is expected to play a central role in Tesla’s Robotaxi ambitions as the company looks to expand autonomous ride-hailing operations beyond its early deployments using Model Y vehicles.
Tesla has also linked Cybercab production to its proposed Unboxed manufacturing process, which assembles large vehicle modules separately before integrating them. The approach is intended to reduce production costs and accelerate output.
Musk has also noted that the Cybercab’s ramp will likely begin slowly due to the number of new components and manufacturing steps involved. However, he stated that once the process matures, Cybercab production could scale quickly.

Elon Musk’s xAI, creator of Grok and Grokipedia, celebrates its third birthday
xAI Memphis highlighted several of its milestones over the years in its celebratory post.
Elon Musk’s artificial intelligence startup xAI has marked its third anniversary. The update was shared in a post from the xAI Memphis account on social media platform X.
xAI Memphis highlighted several of its milestones over the years in its celebratory post.
As per xAI, it has built three massive data centers in the city, launched a coherent cluster of 330,000 GBs, created over 3,000 jobs, and paid over $30 million in taxes to local communities.
xAI’s Memphis operation has become a key part of the company’s infrastructure as the company works to train and deploy its Grok artificial intelligence models. Elon Musk has been quite optimistic about Grok’s potential, noting in the past that the large language model might have a shot at achieving artificial general intelligence (AGI).
xAI’s Memphis’ crown jewel is its Colossus supercomputer cluster. The project was announced in 2024 and has since become the home of one of the world’s largest AI compute facilities. The first phase of Colossus reached its initial 100,000 GPU operational milestone in just 122 days, or just about four months.
Industry figures such as Nvidia CEO Jensen Huang have praised the facility, noting that projects of similar scale typically take two to four years to complete.
xAI has cited Memphis’ central location, skilled workforce, and industrial infrastructure as key reasons for selecting the city as the home of its AI training operations. The company has also emphasized plans to expand the site further as it scales compute capacity for Grok and future AI models.
