Tesla Battery Day vs. Volkswagen Power Day: How Wall Street reacted
Tesla’s Battery Day and Volkswagen’s Power Day were two similar events that showed how the two automakers plan to combat electric vehicle prices within the next few years. Despite the similarities in the events, Wall Street reacted quite differently to both, with Tesla (NASDAQ: TSLA) seeing a minimal effect on its stock in the days following. However, Volkswagen’s stock (OTCMKTS: VWAGY) is soaring over 12% on the day after the event.
Tesla Battery Day
Tesla’s Battery Day was a marquee event for the electric automaker. While the previous year’s focus was Autonomy, 2020 saw battery cells as Tesla’s main concentration. During the event, CEO Elon Musk revealed how Tesla would combat battery prices by continuing to source cells from third-party suppliers, but also by developing its own 4680 cells that are produced by the company in-house. Additionally, new structural battery packs are being used to house the cells and also provide a more robust crash response in the event of an accident. The rigidity of the new structural battery intends to take Tesla’s safety ratings through the roof, where they already reside.
Tesla also revealed plans for a $25,000 car, a blueprint to manufacture 20 million cars per year, and a roadmap to massive cuts in battery cell production costs.

Despite the developments, Tesla didn’t receive a big boost on Wall Street. Interestingly, despite the massive developments and plans that Tesla had revealed during the Battery Day event on September 22nd, 2020, the stock closed at $424.23. The day following saw an 11% drop in the stock, as it closed at $380.36.
Many didn’t understand the reason for the drop. Tesla bull and investor Jim Cramer, who was at one time bearish on the automaker’s stock, stated that the stock fell simply because Tesla didn’t announce what some were expecting. “They’re just bummed the things they hyped didn’t happen,” Cramer said. “Tesla rolls out a plan to create an electric car for the masses and greeted with a yawn because Musk didn’t roll out a magic battery. This is what happens when you let expectations get out of control.”
Volkswagen Power Day
Volkswagen’s Power Day was, in effect, the German automaker’s version of Tesla’s Battery Day. The company held an event outlining their plans for cell cost reductions, along with plans for six total production plants across Europe. VW also has established several partnerships with European energy companies to roll out an expansive charging infrastructure, among many other developments.
“We aim to reduce the cost and complexity of the battery and at the same time increase its range and performance,” Volkswagen Group Board Member for Technology Thomas Schmall said. “We will use our economies of scale to the benefit of our customers when it comes to the battery too. On average, we will drive down the cost of battery systems to significantly below €100 per kilowatt-hour. This will finally make e-mobility affordable and the dominant drive technology.”
Volkswagen’s Power Day: Six new cell plants, new unified battery cell, charging network partnerships
Volkswagen stock began Monday’s trading session at $28.38. After the developments that VW announced, the stock shot up $1.38, a boost of 4.86%. However, the German company’s stock is enjoying massive gains today, just one day after the big event. After closing at $29.76 yesterday, VW stock has increased another 3.48% at the time of writing, for a total gain of 11.69% as of 2:30 PM EST.
The differences in the presentations and how Wall Street has responded to them are unknown. However, the sheer size of Volkswagen’s production figures could be the main reason for the increased investor response. While Tesla’s rollout of 500,000 vehicles in 2020 was a company best, Volkswagen delivered 9.3 million vehicles last year. For context, VW has also been around since 1937, while Tesla has only produced a mass-market vehicle since 2017.
Tesla is undoubtedly the leader in electric vehicles. Volkswagen, while still working out software kinks, could be considered second-place by some because of the successful adaptation of the ID. family of vehicles in Europe so far. However, it is still admittedly ironing out some software issues with its MEB platform, and it seems somewhat odd that VW’s stock received such a healthy boost in the day following its Power Day event.

SpaceX just locked up a NASA record no other U.S. spacecraft can touch
SpaceX’s Crew-13 Dragon reached the ISS in under eight hours, and NASA confirmed a record.
SpaceX now owns every spot on the list of the five fastest trips a U.S. spacecraft has ever made to the International Space Station, and its newest entry beat the old mark by more than four hours.
Crew Dragon Grace docked to the forward port of the station’s Harmony module at 7:05 p.m. ET on October 1, just 7 hours and 55 minutes after lifting off from Space Launch Complex 40 at Cape Canaveral. NASA confirmed the milestone in a space station blog update, writing that the flight “marked the fastest launch‑to‑docking of a U.S. spacecraft in the history of the International Space Station.”
The previous U.S. record also belonged to Dragon. SpaceX’s uncrewed CRS-31 cargo mission reached the station in a little over 12 hours in November 2024. The fastest crewed trip before last week was Crew-11, which took 14 hours and 43 minutes in August 2025, according to Space.com.
A post that Elon Musk reposted on Monday filled out the rest of the ranking. Behind Crew-13, CRS-31 and Crew-11 sit Axiom’s Ax-2 mission at 15 hours and 35 minutes and NASA’s Crew-4 at 15 hours and 44 minutes. All five flew on Dragon.
SpaceX turned a heralding moment for Starship into its greatest
Crew-13 carried NASA astronauts Jessica Watkins and Luke Delaney, Canadian Space Agency astronaut Joshua Kutryk, and Roscosmos cosmonaut Sergey Teteryatnikov. NASA had projected a docking around 8 p.m. ET, as Teslarati reported the day before launch, and Dragon arrived nearly an hour early. Our launch day coverage noted that the flight was lined up to be the quickest Crew Dragon transit yet.
The speed came from timing more than hardware. SpaceX’s Julianna Scheiman said the station “was in an opportune spot in space,” which let Dragon start closing the gap almost immediately after reaching orbit. “This is close to the fastest it could be,” she added. Most Crew Dragon flights still take close to a day, using a series of Draco thruster burns to raise and phase their orbit before arrival.
Dragon’s next job at the station is a departure. NASA said Monday it is targeting 8:05 a.m. ET on Wednesday, October 7, for Crew-12 to undock, setting up a splashdown off the coast of California around 11:34 a.m. on Thursday. Clearing that port makes room for CRS-35, a cargo Dragon carrying the final set of iROSA solar arrays.
Dragon remains NASA’s only operational ride to the station while Boeing’s Starliner stays grounded, and the agency recently added Crew-15, Crew-16 and Crew-17 to SpaceX’s contract in a $946 million modification.
Elon Musk has acknowledged that early discussions with Taiwan Semiconductor Manufacturing Company (TSMC) could bring the company into his ambitious Terafab semiconductor project, signaling a possible partnership with the world’s leading contract chipmaker.
Musk confirmed that early talks are underway, but as of right now, they are “just discussions.” There is no confirmation of a deal nor dismissal of the possibility of one, leaving open the prospect of one of the largest advanced-chip collaborations under discussion in the U.S.
@wholemars Just discussions, but something may come of it
— Elon Musk (@elonmusk) October 3, 2026
The report that speculated on potential discussions between Terafab and TSMC comes from Tim Culpan, who outlined a few ways the collaboration could operate. One is TSMC using the project as an “anchor customer” for future facilities in Texas, potentially contributing process expertise, operational know-how, or capacity while Terafab provides capital, long-term purchase commitments, or both.
Tesla and SpaceX jointly developed the Terafab project, with Intel already participating on the tech side. Elon Musk announced the project in March, and it intends to produce more than one terawatt of AI compute capacity annually once fully built.
Company statements place the first phase at approximately $16.8 billion in cost, with later filings pointing to a total that could reach well into the tens of billions across multiple stages.
Intel joined the effort in April 2026 and is expected to supply its 14A manufacturing process for the full-scale plant.
Musk has said existing suppliers, including Samsung and TSMC, remain important for near-term needs; Tesla already has production arrangements with Samsung for AI5 and AI6 chips, but that future demand from Optimus robots, Cybercab vehicles, and planned space-based data centers will eventually exceed what the global industry can currently deliver.
Terafab is positioned as the long-term answer to that projected shortfall, and Tesla did something similar during COVID to avoid a chip shortage. This is just a much larger-scale solution.
If the partnership were to materialize, it would add TSMC’s industry-leading strategies to a project that already combines Tesla’s and SpaceX’s capital and offtake with Intel’s process technology. For now, the only public confirmation is Musk’s brief acknowledgement that conversations are occurring.
Tesla’s early strategy for charging units operating within its Robotaxi fleet reveals that the company surely has not lost any of that scrappy DNA that took it from an unlikely success story to the most valuable carmaker in the world.
An observer at a Tesla Supercharger in Austin spotted ten total Robotaxi vehicles arrive: one Cybercab and nine Model Y units. A Tesla employee was waiting at the lot and allowed each unit to park itself; every car that arrived had nobody in it.
Tesla wins FCC approval for wireless Cybercab charging system
The Tesla employee would walk around and plug each car in, adjusting the parking if needed:
So look at what I found. This is how Tesla charges unsupervised robotaxis at a public supercharger. Here is a driverless Cybercab showing up with no one in it. There are 9 other Model Ys that showed up too. A Tesla employee is walking around and plugging each of them in. She also moves the cars if they are not positioned well enough to charge. I love this process. One person charges multiple robotaxis at once
— Abhimanyu Yadav (@WorldlyReviewer) October 3, 2026
It’s a very interesting strategy, but extremely understandable at this early point in the Robotaxi program. It’s only been out for about 15 months, and Cybercab just entered the fleet in early September.
On top of that, Tesla is still working tirelessly on its wireless charging apparatus, and a new patent was just published regarding that product last week.
However, this is just another example of how Tesla still has plenty of that scrappy DNA leftover from the “production hell” days, when CEO Elon Musk slept on the floor of the factory, employees were working crazy hours, Tesla was building Sprung Structures to build cars in, and the company was tiptoeing on the brink of bankruptcy.
@Teslarati Sheer magnitude of the entire production system is hard to appreciate. Almost every element of production is >75% automated. Only wire harnesses & general assembly, which are <10% of production costs, are primarily manual.
— Elon Musk (@elonmusk) October 12, 2020
For now, Tesla is utilizing a simple system for recharging its ride-hailing vehicles, and that is a Tesla employee doing it manually until another solution presents itself. Sure, it’s not the most high-tech thing, and it certainly is not what people might have expected at this point in time, but it works, and it’s keeping the entire suite running.
