Tesla’s role as supplier of million-mile batteries to be shunned by rival carmakers: professor
Elon Musk has been pretty open to the idea of Tesla eventually becoming a supplier of key EV components like batteries to other carmakers. This is especially notable considering that Tesla’s powertrain and batteries are second to none, being the secret sauce of sorts to the efficiency, power, and performance of the company’s lineup of premium electric cars.
The Tesla CEO emphasized this stance last month, when he noted on Twitter that “Tesla is open to licensing software and supplying powertrains & batteries. We’re just trying to accelerate sustainable energy, not crush competitors!” Musk’s statement actually rings true, considering that the company has played the role of battery supplier to Daimler and Toyota in the past.
Tesla’s notable edge in the electric vehicle market suggests that a move to the role of a battery and powertrain supplier is well within the company’s goals. This is especially notable amidst Tesla’s highly-anticipated efforts to roll out and introduce a million-mile battery, which would likely be game-changing for the EV market. Considering Tesla’s place in the global EV segment, one would likely infer that the company’s batteries would be received positively by other carmakers.
Prof. Hwang Sung-ho, a mechanical engineering professor at Sungkyunkwan University in South Korea, begs to differ, as he believes that Tesla’s transition to the role of battery supplier may not be as smooth as expected by the company’s supporters. In a statement to The Korea Herald, Prof. Hwang stated that Tesla’s place in the auto market could actually discourage rival EV makers from using Tesla’s batteries, even if the company comes out with industry-leading cells like the million-mile battery.
“There is a possibility that Tesla will offer its own batteries to automakers because the more batteries it makes, the cheaper they become. However, automakers won’t buy batteries from Tesla no matter how good they may be because Tesla is basically their competitor in the auto market,” Hwang said.
The professor added that veteran carmakers, some of whom could make better cars than Tesla, would likely hesitate to purchase cells from the Elon Musk-led company. Hwang explained that by partnering with Tesla and acquiring their batteries, legacy carmakers, particularly those from Europe, will risk exposing their trade secrets to the younger EV maker.
“If an automaker decides to develop a new EV and load it with Tesla’s batteries, then the automaker has to share and exchange so much detailed technological information with Tesla for several years for the optimization of batteries. European automakers, who can make cars better than Tesla, won’t risk exposing their know-how. Only Chinese automakers or those who don’t have a technological lead against Tesla will consider supplying batteries from the company,” the professor said.
Regardless of Prof. Hwang’s reservations, the allure of Tesla’s batteries would likely be attractive for other automakers nonetheless. Tesla, after all, may be a young carmaker, but it is one of the market’s most experienced electric vehicle producers today. This means that the company knows EVs inside out, and this is one of the reasons why its vehicles like the Model Y Dual-Motor AWD could go beyond 300 EPA miles on a 75 kWh battery. Ultimately, if Tesla offers its powertrain and batteries at a reasonable price, there is a pretty good chance that the company will be well received by other carmakers.
Tesla Full Self-Driving (Supervised) has taken yet another significant step forward in Europe. On May 29, Estonia became the third European Union country to approve the advanced driver-assistance technology, following approvals in the Netherlands and Lithuania.
Tesla Europe announced the news on X, confirming the expansion has continued across the continent that, at one time, seemed to be taking its sweet old time giving any approval to the FSD suite.

Estonia’s Transport Administration (Transpordiamet) granted the approval by recognizing the type certification issued by the Dutch vehicle authority RDW. This mutual recognition mechanism, enabled by EU regulations, allows other member states to fast-track deployment without repeating extensive local testing.
The Estonian authority noted that Tesla’s FSD had undergone rigorous evaluation on European roads for approximately 18 months before the initial Dutch approval in April 2026.
FSD Supervised remains classified as a Level 2 advanced driver-assistance system (ADAS). Drivers must maintain full attention, keep their hands on the wheel, and stay ready to intervene at any moment.
The system assists with tasks such as automatic lane changes, navigation through city streets, and responding to traffic objects, but it does not constitute full autonomy. Estonian officials emphasized this distinction, underscoring that safety responsibility lies entirely with the driver.
The rapid progression across the Baltic region highlights Tesla’s strategic approach to European expansion. The Netherlands provided the foundational type approval in April, unlocking doors for neighboring countries.
Lithuania followed swiftly in mid-May, with rollout beginning shortly thereafter. Estonia’s decision, coming just days later, demonstrates how smaller, digitally progressive nations are accelerating adoption.
Tesla owners in Estonia can expect an over-the-air software update in the coming weeks, bringing the latest FSD capabilities to compatible vehicles
This expansion builds on Tesla’s global momentum. FSD Supervised is now available in 11 countries worldwide, including the United States, Canada, Australia, and South Korea. In Europe, the approvals signal growing regulatory confidence in Tesla’s vision-based AI approach, which relies on cameras and neural networks rather than lidar or radar-heavy alternatives used by some competitors.
For Tesla, these European milestones are more than symbolic. They validate years of data collection and software iteration while opening new revenue streams through FSD subscriptions and purchases.
As the company continues refining its AI models with real-world miles from diverse driving environments, including Estonia’s variable winter conditions, the dataset grows richer, potentially benefiting global users.
Elon Musk has firmly denied recent media reports suggesting that SpaceX has reduced its target valuation for an upcoming initial public offering.
The denial came directly from the SpaceX and Tesla frontman on his social media platform X, where he responded with a single word, “False,” to a post from ZeroHedge that cited Bloomberg sources.
This swift rebuttal underscores Musk’s ongoing effort to manage speculation surrounding one of the most anticipated market debuts in recent history.
False

According to the disputed reports, SpaceX had lowered its IPO valuation goal to at least $1.8 trillion from previous ambitions exceeding $2 trillion.
The claims emerged amid growing anticipation for the company’s confidential S-1 filing, which positions it for a potential public listing as early as June.
Some had pointed to strong revenue growth, particularly from the Starlink satellite internet service, which contributed heavily to the firm’s 2025 figures of $18.7 billion. Yet challenges persist in other areas, including substantial investments and losses tied to ambitious projects like Starship development and artificial intelligence initiatives, which plan to make life multiplanetary eventually.
Musk’s response highlights a pattern in which he actively counters what he views as inaccurate portrayals of his companies’ trajectories.
SpaceX, already valued privately at extraordinary levels, stands as a cornerstone of Musk’s empire alongside Tesla and xAI. The entrepreneur has long emphasized the transformative potential of reusable rockets and global broadband access, factors that fuel investor enthusiasm despite operational hurdles.
By rejecting the valuation downgrade narrative, Musk signals confidence in SpaceX’s fundamentals and its readiness for public markets on terms favorable to its long-term vision. People have been waiting a very long time to invest in SpaceX, and the valuation, as well as the introductory share price, is not going to need adjusting.
They’ll have plenty of suitors.
This episode reflects broader dynamics in the technology sector, where rumors often swirl around high-profile entities. Musk’s direct engagement with media narratives serves to maintain transparency and control the narrative around his ventures.
As SpaceX prepares for greater scrutiny in public markets, the founder’s denial reinforces optimism about its prospects. Supporters argue that the company’s innovative edge positions it for enduring success, far beyond short-term valuation debates. With the denial now public, attention turns to forthcoming regulatory filings that could provide clearer insights into SpaceX’s strategy and financial health.
The coming weeks promise to reveal more about how SpaceX will transition into a publicly traded powerhouse.
Tesla’s dreams of operating a fully autonomous ride-hailing platform just took a massive step toward reality, as two separate events have indicated the company is perhaps closer than ever to achieving self-driving as a product.
On Thursday, Tesla was granted authorization by the State of Texas to operate driverless vehicles in a commercial manner. On May 28, Senate Bill 2807, passed by the 89th Texas Legislature, took effect after being passed back on September 1, 2025.
The bill establishes a statewide regulatory framework requiring authorization from the Texas Department of Motor Vehicles for companies to operate automated vehicles commercially on Texas roads.
This covers driverless, or SAE Level 4+, operations for passenger transport, meaning Robotaxi, or freight.
Tesla and other companies can self-certify their vehicles and tech as long as they:
- Operate in compliance with Texas traffic laws
- Maintain proper registration, title, and insurance
- Use compliant automated driving systems
- Record onboard activity and handle system failures and glitches safely.
The new authorization, which was first reported by James Stephenson on X, allows companies to utilize their own processes to determine if their vehicles are ready to operate without drivers.
🚨BREAKING:

It is a rule that expedites the entire approval process, keeping agencies out of a usually long, lengthy, and frustrating task that is essential to technological advancements. It essentially means Tesla can launch commercial Robotaxi operations at this point.
On the very same day, Tesla continued the momentum as CEO Elon Musk shared a video of Cybercab units autonomously driving off the property at Gigafactory Texas. This is a major step in the story of the Cybercab.
Mass production of the Cybercab started at Giga Texas in April, and it is already heading out of the factory on its own.

These two major events mark a drastic step forward in Tesla’s progress toward Cybercab and the permissions it needs to operate a self-driving ride-hailing service. Tesla is now able to operate autonomously under Texas law by self-certifying, and with the potentially imminent rollout of Cybercab, Tesla’s autonomous dreams are starting to take serious shape.
