Tesla Semi production rumors swirl as frequent sightings up the ante on expectations
Rumors surrounding the Tesla Semi are plentiful in this day and age, especially as sightings of the company’s commercial vehicle are becoming more frequent. Expectations for the new Semi are high already, and Tesla aims to deliver the truck in a timely fashion after several delays.
The new Semi has been spotted numerous times over the past week, hinting toward ongoing testing before Tesla starts volume production of the massive, all-electric commercial vehicle. Less than two weeks after Tesla’s Q4 2020 Earnings Call, where CEO Elon Musk and others detailed the ongoing offensive to develop the vehicle, the Semi is being spotted by people on public roads. Although Musk stated battery constraint is the hold-up in the Semi’s production, it isn’t stopping the company from testing several new truck builds.
Speculation regarding when Tesla will finally begin volume production is growing, and more rumors surrounding the initial deliveries to pre-orderers appear on what seems like a daily basis. However, the big bottleneck is batteries, and Tesla plans to combat this issue with wide-scale cell production and purchasing. The real question is, how many cells will be “enough?”
EXCLUSIVE: For a few weeks I’ve been in contact with a source from a U.S Tesla supplier. They supply certain parts for the S,X,3 and Y, but I’m here to reveal some info on Tesla Semi. As always, take these kinds of things with a grain of salt. Things/timelines can change.

Elon Musk’s Earnings Call Comments
Musk, who stated last year that it was time for Tesla to enter volume production of the Semi, had a different tune during the Q4 2020 Earnings Call on January 27th. Battery cell constraint is a major bottleneck in starting the Semi production, as fulfilling the number of orders it has would likely inhibit Tesla from being able to produce its mass-market passenger vehicles, like the Model 3 and Model Y.
Tesla has recently started producing its own battery cells at a plant that sits adjacent to its main production facility in Fremont, California. Known as the “Kato Road Facility,” Tesla is building its new 4680 cells there, a battery that Tesla claims will cut the cost of its vehicles massively, putting it on a crash course to reach price parity with gas-powered vehicles. The Semi will require significantly more cells than any other Tesla vehicle to date, a problem that the company is aiming to solve by producing its own cells and buying additional ones from third-party suppliers like Panasonic.
Tesla’s 4680 Kato Rd. facility has a top 10 capacity, and it’s not even close to finished
During the Earnings Call, Musk said:
“Prototypes are easy. Scaling production is very hard. So a big part of the reason — the main reason we have not accelerated new products is — like, for example, Tesla Semi is that we simply don’t happen our cells group. We — this — if we were to make the Semi like right now, which we could easily go into production with the Semi, but we would not have enough to cells built for it right now. We will have cells group in ourselves for Semi when we are producing the 4680 volume. But for example, Semi would use typically five times the number of cells that a car would use, but it would not sell for five times what a car would sell for. So it kind of doesn’t make — it would not make sense for us to do the Semi right now, but it will absolutely make sense for us to do it as soon as we can address the cell production constraint. The same would go for that.”
Effectively, Musk explained that it makes more fiscal sense to focus on the mass-market consumer products for right now. When the Kato Rd. Facility begins a massive production of the 4680 cells, Tesla can begin the Semi production efforts, but that doesn’t mean prototypes aren’t on the road now.
New Sightings
Following a sighting by The Kilowatts last week, two new sightings of the Semi have surfaced of the all-white Tesla commercial vehicle.

One video from Cory Draper on YouTube shows a four-and-a-half-minute-long walk around of the Semi, getting a close-up look at the vehicle. One of the most striking features is the size of the power cell, as Draper estimates it is between four and five feet in length. A massive truck requires a massive power source, and the Semi’s sizeable battery storage compartment will drive the truck’s 300 or 500-mile range. Another video from Ivaylo Tzintzarsky shows the power cell from the opposite side.

There are also numerous sensors that can be seen on the Semi, especially in Draper’s video. The top of the windshield is outfitted with at least five sensors that will help with the autonomous driving functionality of the Tesla Semi. Autonomy could help with the evolution of the trucking industry, as many drivers are currently restricted to 11 hours of travel per day, according to the Federal Motor Carrier Safety Administration (FMCSA).
Fuel savings alone could pay for a Tesla Semi, as the company estimates it will save at least $200,000. Combined with superior aerodynamic performance and, a quad-motor powertrain, and a low center of gravity to prevent rollovers, the Tesla Semi has the potential to revolutionize the trucking industry forever. The question is: When will it begin production, and how long until Tesla can produce the 4680 cells in mass quantities to solve the constraint issue?

Tesla CEO Elon Musk certainly tipped off some details of the Tesla Roadster event with a broadening of information regarding the company’s decision to delay the unveiling for two weeks.
For years, people have speculated about what the Roadster will be capable of. While there have been plenty of things said about what it *could* do, we have not seen or been told by Tesla what it will actually be capable of.
However, over the past few days, Tesla’s weather updates have truly pushed the speculation into Plaid Mode, basically all but confirming the car will have some sort of aerial capability — whether that would be hovering or fully flying remains to be seen — but it definitely seems that it will be able to leave the ground intentionally.
“Because this event can only be held outdoors…”
Tesla posted on Monday that it would delay the Roadster event until October 15, and it indicated that it had to do this because the event “can only be held outdoors.”
With the potential SpaceX collaboration to develop cold-gas thrusters that will help the vehicle go airborne, doing this indoors is probably not a safe, or even plausible, possibility.
Roadster event update
We’ve been tracking the weather closely with local meteorologists, but given the severe conditions predicted & because this event can only be held outdoors, we’ve made the difficult decision to reschedule.
New date is October 15. Additional details to…

FAA Airspace Restriction
The FAA gave Tesla a Temporary Flight Restriction (TFR) for 10,000 feet above ground level, much higher than the typical 2,000-foot restrictions that are usually placed at SpaceX’s McGregor, Texas site.
Tesla Roadster event requires restricted airspace, and the FAA obliges
Some have said that this massive increase is due to Tesla’s need to restrict unauthorized drone use for spying on the event.
Elon Admits High Winds
“Due to high winds, the new Roadster demo is postponed by 2 weeks,” Musk said in a post on X yesterday.

A reply reading, “What’s strong wind got to do with a car demo with four grounded wheels?” was directly below Musk’s post, satirically and sarcastically probing for more details.
All signs are pointing toward an aerial demonstration for the Roadster.
Tesla has secured $30 billion in fresh credit lines from Citibank and Wells Fargo in an effort to scale its biggest current projects.
Tesla agreed to a $20 billion three-year delayed-draw term loan facility from Citibank, it announced on Tuesday. Additionally, it signed a five-year, $8 billion revolving credit facility and a $2 billion, 364-day term credit facility with Wells Fargo.
In a filing with the Securities and Exchange Commission (SEC), that it “may draw” from the $20 billion delayed-draw term “from time to time” and “no more than ten times during the 18 months following the closing date.” This loan matures on September 29, 2029.
The five-year revolving facility from Wells Fargo will also be accessed by Tesla “from time to time,” and will become due and payable on September 29, 2031. Tesla can request two separate one-year extensions.
On the $2 billion, 364-day revolving loan, it becomes due and payable on September 28, 2027. Tesla can also increase its additional commitments to an additional $4 billion across the Revolving Facilities. This would increase the total facilities to $14 billion. Tesla said it does not plan to utilize any of these loans in 2026.
Tesla plans to utilize the money to help prop up its ambitions to scale its biggest products, each of which is either in early launch phases or still in development. Of course, we’re talking about Cybercab and Semi, which have launched, and Optimus, which is still under heavy development and working toward initial release.
All three Tesla products have one thing in common: they’ve all required Tesla to build new manufacturing lines for them.
For the Semi, Tesla built a brand new factory in Sparks, Nevada, adjacent to the Tesla Gigafactory. For Optimus, Tesla sunset Model S and X production at the Fremont Factory, which brought an end to the two flagship models, thus creating manufacturing space for the humanoid robot. Finally, Cybercab is being built at Gigafactory Texas and officially entered production earlier this year.
The cash will help Tesla bolster its finances for the continuing development of these products. Tesla said that it forecasts its CapEx to be over $25 billion, up from just over $8.5 billion last year. These loans surely help with that spending.

Elon Musk and Trump are closer than ever, and Tesla could be the big winner
Elon Musk sat beside Trump as AI leaders signed a voluntary White House safety accord.
Elon Musk had the seat right next to President Donald Trump on Tuesday as the White House hosted the leaders of America’s biggest artificial intelligence companies for a lunch that ended with a voluntary industry accord on AI safety.
A seating chart Trump posted on Truth Social placed Musk at the president’s left in the East Room, with Nvidia CEO Jensen Huang on his right, according to an Associated Press reporter. Anthropic CEO Dario Amodei, OpenAI President Greg Brockman, Meta’s Mark Zuckerberg, Google’s Sundar Pichai, Microsoft’s Satya Nadella and Amazon founder Jeff Bezos also attended, along with Vice President JD Vance and House Speaker Mike Johnson.

After the lunch, Trump told reporters outside the West Wing that the executives had signed “The White House Accord on Superintelligence: A Joint Commitment on Frontier SI Responsibilities.” Johnson described it as a voluntary statement of principles built on “robust internal controls and layers of internal and external review,” while Zuckerberg said company boards would independently review reports from outside auditors. Trump called the document “morally binding,” said he would name a new AI czar within days, and signed an executive order formally renaming artificial intelligence “super intelligence,” CNBC reported.
Musk was not in the room for Tesla alone. Since SpaceX absorbed xAI, he runs the company behind Grok and one of the largest AI training operations anywhere. On September 25, he said another 220,000 Nvidia GB300 chips would come online at Colossus 2 within a week, with more expected in November and December.

Musk also used the trip to restate his energy ambitions. “SpaceX is aiming together with Tesla to do 200 gigawatts of solar production per year,” he said at an event in Washington. It is the same combined target he laid out that feeds directly into Terafab, the Tesla and SpaceX chip venture that will need enormous amounts of power.
The showing between Musk and Trump has come a long way, since the two had the very public split in mid 2025 after Musk opposed the “Big Beautiful Bill” and left DOGE. They reconciled at Charlie Kirk’s memorial that September, and Trump later called their relationship “good”. Since then, Musk has joined Trump’s China delegation in May and attended last week’s White House state dinner for Chinese President Xi Jinping.
For Tesla, that access to government official could pay dividends. As Teslarati noted in January, federal autonomy rules, NHTSA oversight and a single national standard for driverless vehicles all run through an administration Musk can more easily reach directly as Tesla works to scale Robotaxi and Cybercab beyond Texas.
