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.

What is Digital Optimus? The new Tesla and xAI project explained
At its core, Digital Optimus operates through a dual-process architecture inspired by human cognition.
Tesla and xAI announced their groundbreaking joint project, Digital Optimus, also nicknamed “Macrohard” in a humorous jab at Microsoft, earlier this week.
This software-based AI agent is designed to automate complex office workflows by observing and replicating human interactions with computers. As the first major outcome of Tesla’s $2 billion investment in xAI, it represents a powerful fusion of hardware efficiency and advanced reasoning.
At its core, Digital Optimus operates through a dual-process architecture inspired by human cognition.
Macrohard or Digital Optimus is a joint xAI-Tesla project, coming as part of Tesla’s investment agreement with xAI.

Tesla’s specialized AI acts as “System 1”—the fast, instinctive executor—processing the past five seconds of real-time computer screen video along with keyboard and mouse actions to perform immediate tasks.
xAI’s Grok model serves as “System 2,” the strategic “master conductor” or navigator, providing high-level reasoning, world understanding, and directional oversight, much like an advanced turn-by-turn navigation system.
When combined, the two can create a powerful AI-based assistant that can complete everything from accounting work to HR tasks.
Will Tesla join the fold? Predicting a triple merger with SpaceX and xAI
The system runs primarily on Tesla’s low-cost AI4 inference chip, minimizing expensive Nvidia resources from xAI for competitive, real-time performance.
Elon Musk described it as “the only real-time smart AI system” capable, in principle, of emulating the functions of entire companies, handling everything from accounting and HR to repetitive digital operations.
Timelines point to swift deployment. Announced just days ago, Musk expects Digital Optimus to be ready for user experience within about six months, targeting rollout around September 2026.
It will integrate into all AI4-equipped Tesla vehicles, enabling parked cars to handle office work during downtime. Millions of dedicated units are also planned for deployment at Supercharger stations, tapping into roughly 7 gigawatts of available power.
Oh and it works in all AI4-equipped cars, so your car can do office work for you when not driving.
We’re also deploying millions of dedicated Digital Optimus units in the field at Superchargers where we have ~7 gigawatts of available power.

Digital Optimus directly supports Tesla’s broader autonomy strategy. It leverages the same end-to-end neural networks, computer vision, and real-time decision-making tech that power Full Self-Driving (FSD) software and the physical Optimus humanoid robot.
By repurposing idle vehicle compute and extending AI4 hardware beyond driving, the project scales Tesla’s autonomy ecosystem from roads to digital workspaces.
As a virtual counterpart to physical Optimus, it divides labor: software agents manage screen-based tasks while humanoid robots tackle physical ones, accelerating Tesla’s vision of general-purpose AI for productivity, Robotaxi fleets, and beyond.
In essence, Digital Optimus bridges Tesla’s vehicle and robotics autonomy with enterprise-scale AI, promising massive efficiency gains. No other company currently matches its real-time capabilities on such accessible hardware.
It really could be one of the most crucial developments Tesla and xAI begin to integrate, as it could revolutionize how people work and travel.

Interestingly, we’re not too sure what catalyzed Tesla to try to improve braking smoothness, because it hasn’t seemed overly abrupt or rough from my perspective. Although the brake pedal in my Model Y is rarely used due to Regenerative Braking, it seems Tesla wanted to try to make the ride comfort even smoother for owners.
There is always room for improvement, though, and it seems that there is a way to make braking smoother for passengers while the vehicle is coming to a stop.
This is far from the first time Tesla has attempted to improve its ride comfort through Over-the-Air updates, as it has rolled out updates to improve regenerative braking performance, handling while using Full Self-Driving, improvements to Steer-by-Wire to Cybertruck, and even recent releases that have combatted Active Road Noise.
Tesla holds a unique ability to change the functionality of its vehicles through software updates, which have come in handy for many things, including remedying certain recalls and shipping new features to the Full Self-Driving suite.
Tesla seems to have the most seamless OTA processes, as many automakers have the ability to ship improvements through a simple software update.
We’re really excited to test the update, so when we get an opportunity to try out Comfort Braking when it makes it to our Model Y.

Tesla finally brings a Robotaxi update that Android users will love
The breakdown of the software version shows that Tesla is actively developing an Android-compatible version of the Robotaxi app, and the company is developing Live Activities for Android.
Tesla is finally bringing an update of its Robotaxi platform that Android users will love — mostly because it seems like they will finally be able to use the ride-hailing platform that the company has had active since last June.
Based on a decompile of software version 26.2.0 of the Robotaxi app, Tesla looks to be ready to roll out access to Android users.
According to the breakdown, performed by Tesla App Updates, the company is preparing to roll out an Android version of the app as it is developing several features for that operating system.
🚨 It looks like Tesla is preparing to launch the Robotaxi app for Android users at last!

The breakdown of the software version shows that Tesla is actively developing an Android-compatible version of the Robotaxi app, and the company is developing Live Activities for Android:
“Strings like notification_channel_robotaxid_trip_name and android_native_alicorn_eta_text show exactly how Tesla plans to replicate the iOS Live Activities experience. Instead of standard push alerts, Android users are getting a persistent, dynamically updating notification channel.”
This is a big step forward for several reasons. From a face-value perspective, Tesla is finally ready to offer Robotaxi to Android users.
The company has routinely prioritized Apple releases because there is a higher concentration of iPhone users in its ownership base. Additionally, the development process for Apple is simply less laborious.
Tesla is working to increase Android capabilities in its vehicles
Secondly, the Robotaxi rollout has been a typical example of “slowly then all at once.”
Tesla initially released Robotaxi access to a handful of media members and influencers. Eventually, it was expanded to more users, so that anyone using an iOS device could download the app and hail a semi-autonomous ride in Austin or the Bay Area.
Opening up the user base to Android users may show that Tesla is preparing to allow even more users to utilize its Robotaxi platform, and although it seems to be a few months away from only offering fully autonomous rides to anyone with app access, the expansion of the user base to an entirely different user base definitely seems like its a step in the right direction.
