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.

OpenAI cites distrust of SpaceX in decision to drop Cursor partnership
OpenAI will cut SpaceX-owned Cursor’s model access in November, citing Musk’s history of broken contracts.
OpenAI, the company behind ChatGPT, announced late Friday that it is ending its partnership with Cursor, cutting off the coding tool’s access to its models on November 12. The move comes two weeks after SpaceX completed its $60 billion acquisition of Cursor’s parent company, Anysphere, folding the popular AI coding assistant into Elon Musk’s growing SpaceXAI division.
In a post on its website, OpenAI said the decision came down to trust, not technology. “We cannot be confident that SpaceX will use our technology within our terms of service, based on our experience with Elon Musk’s companies violating contracts,” the company wrote. OpenAI pointed to two specific incidents: X, now part of SpaceX, allegedly breaking the terms of an existing OpenAI contract after Musk bought Twitter.
That lawsuit is the backdrop for all of this. Musk cofounded OpenAI in 2015, left the board in 2018, and sued Sam Altman and Greg Brockman in 2024, arguing they abandoned the company’s nonprofit mission for profit. A federal jury sided with OpenAI in May, finding Musk waited too long to sue rather than ruling on the merits of his claims. Musk said at the time he would appeal to the Ninth Circuit, calling the outcome a “calendar technicality” rather than a real judgment.
SpaceX’s interest in Cursor predates that verdict by weeks. The company first struck a deal with Cursor in April, securing an option to acquire it for $60 billion or pay $10 billion for joint development work instead. As Teslarati reported at the time, the logic was straightforward: Cursor was paying retail prices to Anthropic and OpenAI, two of its most direct competitors, every time a developer used its product, while SpaceX had idle capacity on its Colossus supercomputer, roughly the equivalent of a million Nvidia H100 GPUs, that Cursor could use to train its own models instead. SpaceX exercised the option in June, days after its own IPO, and the deal closed in mid-August.
Once it closed, Musk moved fast. On an all-hands call with more than 1,000 Cursor employees, he reportedly told staff that SpaceXAI’s Grok was playing catchup in the AI race, unlike Tesla and SpaceX in their own markets, and singled out Anthropic as the company to catch. Cursor CEO Michael Truell now reports directly to Musk inside SpaceXAI.
Losing OpenAI’s models leaves Cursor leaning harder on Anthropic’s Claude, which has its own compute agreement with SpaceX, and on Cursor’s in-house Composer model, the one SpaceX’s compute was supposed to accelerate in the first place. OpenAI framed the November deadline as maximum notice under its contract, and said it wants to “go above and beyond” to help developers through the transition. Whether Anthropic makes the same call is now the open question in AI coding.
The in-car Tesla Theater is among the most unique features available within the cars. When charging, parked, camping, or just hanging out, vehicle occupants can access a variety of streaming platforms on the large center screen, helping keep them entertained during downtime.
However, the Theater might be getting plenty more streaming platforms, something that owners have requested for some time.
Tesla owners recently discovered that visiting Apple TV in the vehicle browser can launch a fullscreen interface that looks and behaves like a dedicated application rather than an ordinary webpage:
Today I learned that if you go to Apple TV in the Tesla browser, it will open up an actual Apple TV app, fully functional. Not just the site.
Apparently there are more apps than just the few that show on the apps page. pic.twitter.com/os1Ypfm4JR

The experience drops the usual address bar and browser chrome, presenting catalogs, continue watching rows, and playback controls in the same window Tesla Theater already uses for its listed services. Independent testers soon found similar treatment for HBO Max, Paramount+, Peacock, Disney+, and Prime Video when those sites are opened from the car browser.
This shift is a plausible early signal that Tesla is widening Theater support without a formal software note. Theater has long been a set of web views rather than native applications, so recognizing extra domains and stripping the browser frame is a small server-side change that can expand the catalog quickly.
Owners still lack permanent Theater icons for the newly recognized services, and video remains limited to Park, yet the smoother launch is a meaningful step toward a broader lounge while charging.
Tesla Theater arrived with software version 10 in September 2019. The first video services were Netflix, YouTube, and Hulu, available only while parked and originally tied to WiFi. Spotify arrived in the same era as music rather than Theater video. Disney+ joined officially in July 2021 with the 2021.24 update, giving owners another major catalog on the center screen. Twitch and TikTok later appeared among the default Theater tiles, and Tesla Tutorials remained a persistent educational tile.
Not every addition stayed put. In December 2023, a Holiday software build removed the Disney+ tile for many United States owners after a public dispute involving advertising on X. Hulu stayed visible even though Disney owned it. Visiting disneyplus.com in the browser often restored the tile, which suggested the removal was a recognition list change rather than a complete block. Owners have also reported occasional blank Theater grids after updates, usually fixed by language toggles, resets, or later firmware.
Tesla axes Disney+ from vehicles with Musk-Iger rivalry, but there’s a workaround
Code archives from 2024 listed many unused source names, including Apple TV and Prime Video, that never became official icons, which now looks like groundwork for the current fullscreen browser behavior.
Now that this hint toward an expanded Theater experience has been recognized, Tesla could follow through with these additional shortcuts as a sign that more streaming platforms are available in Teslas than ever before.
Tesla recently received its largest order for the all-electric Semi from Einride, a Swedish transport service, for 500 units, a groundbreaking invoice to receive before the first deliveries begin.
Even more remarkable, Einride CEO Roozbeh Charli said in a recent interview that he expects his company to take delivery of all 500 — the entire order — before the end of 2027. He even expects to have 75 Tesla Semi units in the Einride fleet before the end of this year.

Charli said the Tesla partnership was part of a broader push, along with its earlier partnership with Amazon. Einride is assisting Amazon with the use of its Saga AI platform, which helps eliminate questions about budgeting and forecasting for logistics companies.
The Semi, as well as Tesla’s production and subsequent delivery of the units to Einride, will help the company “to have a good supply of vehicles that we can deploy on the [Saga AI] platform,” Charli said. “Tesla is also a relationship we’ve had for a while, and as the Tesla Semi deliveries are firming up, we decided to do a larger commitment to that and deploy that on our platform.”
In its initial announcement, Einride said it anticipated taking delivery of the trucks over the next two years, but now it appears the company is expecting all 500 units within the next 16 months.
Built at a dedicated factory in Sparks, Nevada, the Tesla Semi has been perhaps the biggest and most intensive testing process the company has ever had for a single vehicle model. For the past several years, Tesla has been working with many companies, most notably Frito-Lay and PepsiCo, to gain knowledge on the performance on regional routes.
Tesla plans to launch the Semi officially on September 24, five months after production started ramping.
Additionally, drivers have said they are happy about the Semi’s performance and that its numerous safety and productivity features have made their jobs and routes much easier.
