Tesla could benefit as South Korea pushes to update EV incentives
South Korea is the world’s 11th largest car market according to IHS Automotive but 5th in sales of luxury cars like the Mercedes S Class and BMW 7 Series. That means it could be an important market for Tesla’s Model S and Model X. The country ranks in the top six in terms of the number of reservations for the upcoming Tesla Model 3 midsize sedan.
South Korea offers buyers of electric cars a subsidy equivalent to 22 million won or approximately $18,000 dollars but the incentive only applies to cars that can be recharged in 10 hours or less using 220 volt household current.The rule was enacted in 2012 and was intended to encourage manufacturers to limit the charging time required for electric cars. But electric cars today have much larger batteries than they did then. Those larger batteries may take more than 10 hours to recharge on household current, making them ineligible for the subsidy.
Minister of Environment Cho Kyeung-kyu says it may be time for his country to revisit that rule. A ministry official tells Reuters that a government appointed panel will submit recommendations “by June, but it could be much earlier. We haven’t decided whether to keep the rule alive, or kill it, or come up with complementary rules.”
Last month, opposition lawmaker Lee Sang-don called the rule an “unreasonable non-tariff barrier” that discourages drivers from considering long range EVs. “The rule is meaningless,” Kim Pil-soo, president of the Korean Electric Vehicle Association, told Reuters. “We have kept telling the government they should remove it.” In October, Tesla Vice President of North Asia and SEA Nicolas Villeger said the company is working with the government to change a “unique rule” that does not reflect advances in battery technology.
Tesla is about to open its first showroom in the upscale Starfield shopping district east of Seoul. In fact, it was supposed to be open before the end of 2016, but a sign in the window saying “Opening Soon” was still in the window as of last week. A delay in obtaining the permits required to begin sales has pushed the opening to early next year, a person familiar with the matter told Reuters.
Tesla has been accepting orders from Korean customers since August for its Model S and Model X as well as reservations for the Model 3. With the present rule in place, a car that the company expects to sell strongly in the South Korean luxury car market — the Model S 90D — will not be eligible for the electric car incentive because its battery is too large to recharge in less than 10 hours on household current.
Chinese automaker BYD also intends to offer its long range electric car, the e6, for sale in Korea but has delayed starting sales until the incentive rule is amended. The e6 also will require more than 10 hours to fully recharge on household current.
Sales of electric cars in South Korea have been weak so far. To date, there are only about 4,000 EVs registered in the entire country despite the generous subsidy. South Korea has been proactive when it comes to building charging infrastructure. There are 750 fast chargers available to Korean EV drivers at present and the government plans to increase that number to 3,000 by 2020. Tesla is also planning to construct Supercharger locations in Seoul, Busan and Pyeongchang.

Tesla confirms that it finally solved its 4680 battery’s dry cathode process
The suggests the company has finally resolved one of the most challenging aspects of its next-generation battery cells.
Tesla has confirmed that it is now producing both the anode and cathode of its 4680 battery cells using a dry-electrode process, marking a key breakthrough in a technology the company has been working to industrialize for years.
The update, disclosed in Tesla’s Q4 and FY 2025 update letter, suggests the company has finally resolved one of the most challenging aspects of its next-generation battery cells.
Dry cathode 4680 cells
In its Q4 and FY 2025 update letter, Tesla stated that it is now producing 4680 cells whose anode and cathode were produced during the dry electrode process. The confirmation addresses long-standing questions around whether Tesla could bring its dry cathode process into sustained production.
The disclosure was highlighted on X by Bonne Eggleston, Tesla’s Vice President of 4680 batteries, who wrote that “both electrodes use our dry process.”
Tesla first introduced the dry-electrode concept during its Battery Day presentation in 2020, pitching it as a way to simplify production, reduce factory footprint, lower costs, and improve energy density. While Tesla has been producing 4680 cells for some time, the company had previously relied on more conventional approaches for parts of the process, leading to questions about whether a full dry-electrode process could even be achieved.
4680 packs for Model Y
Tesla also revealed in its Q4 and FY 2025 Update Letter that it has begun producing battery packs for certain Model Y vehicles using its in-house 4680 cells. As per Tesla:
“We have begun to produce battery packs for certain Model Ys with our 4680 cells, unlocking an additional vector of supply to help navigate increasingly complex supply chain challenges caused by trade barriers and tariff risks.”
The timing is notable. With Tesla preparing to wind down Model S and Model X production, the Model Y and Model 3 are expected to account for an even larger share of the company’s vehicle output. Ensuring that the Model Y can be equipped with domestically produced 4680 battery packs gives Tesla greater flexibility to maintain production volumes in the United States, even as global battery supply chains face increasing complexity.

Tesla Giga Texas to feature massive Optimus V4 production line
This suggests that while the first Optimus line will be set up in the Fremont Factory, the real ramp of Optimus’ production will happen in Giga Texas.
Tesla will build Optimus 4 in Giga Texas, and its production line will be massive. This was, at least, as per recent comments by CEO Elon Musk on social media platform X.
Optimus 4 production
In response to a post on X which expressed surprise that Optimus will be produced in California, Musk stated that “Optimus 4 will be built in Texas at much higher volume.” This suggests that while the first Optimus line will be set up in the Fremont Factory, and while the line itself will be capable of producing 1 million humanoid robots per year, the real ramp of Optimus’ production will happen in Giga Texas.
This was not the first time that Elon Musk shared his plans for Optimus’ production at Gigafactory Texas. During the 2025 Annual Shareholder Meeting, he stated that Giga Texas’ Optimus line will produce 10 million units of the humanoid robot per year. He did not, however, state at the time that Giga Texas would produce Optimus V4.
“So we’re going to launch on the fastest production ramp of any product of any large complex manufactured product ever, starting with building a one-million-unit production line in Fremont. And that’s Line one. And then a ten million unit per year production line here,” Musk stated.
How big Optimus could become
During Tesla’s Q4 and FY 2025 earnings call, Musk offered additional context on the potential of Optimus. While he stated that the ramp of Optimus’ production will be deliberate at first, the humanoid robot itself will have the potential to change the world.
“Optimus really will be a general-purpose robot that can learn by observing human behavior. You can demonstrate a task or verbally describe a task or show it a task. Even show it a video, it will be able to do that task. It’s going to be a very capable robot. I think long-term Optimus will have a very significant impact on the US GDP.
“It will actually move the needle on US GDP significantly. In conclusion, there are still many who doubt our ambitions for creating amazing abundance. We are confident it can be done, and we are making the right moves technologically to ensure that it does. Tesla, Inc. has never been a company to shy away from solving the hardest problems,” Musk stated.

Rumored SpaceX-xAI merger gets apparent confirmation from Elon Musk
The comment follows reports that the rocket maker is weighing a transaction that could further consolidate Musk’s space and AI ventures.
Elon Musk appeared to confirm reports that SpaceX is exploring a potential merger with artificial intelligence startup xAI by responding positively to a post about the reported transaction on X.
Musk’s comment follows reports that the rocket maker is weighing a transaction that could further consolidate his space and AI ventures.
SpaceX xAI merger
As per a recent Reuters report, SpaceX has held discussions about merging with xAI, with the proposed structure potentially involving an exchange of xAI shares for SpaceX stock. The value, structure, and timing of any deal have not been finalized, and no agreement has been signed.
Musk appeared to acknowledge the report in a brief reply on X, responding “Yeah” to a post that described SpaceX as a future “Dyson Swarm company.” The comment references a Dyson Swarm, a sci-fi megastructure concept that consists of a massive network of satellites or structures that orbit a celestial body to harness its energy.
Reuters noted that two entities were formed in Nevada on January 21 to facilitate a potential transaction for the possible SpaceX-xAI merger. The discussions remain ongoing, and a transaction is not yet guaranteed, however.
AI and space infrastructure
A potential merger with xAI would align with Musk’s stated strategy of integrating artificial intelligence development with space-based systems. Musk has previously said that space-based infrastructure could support large-scale computing by leveraging continuous solar energy, an approach he has framed as economically scalable over time.
xAI already has operational ties to Musk’s other companies. The startup develops Grok, a large language model that holds a U.S. Department of Defense contract valued at up to $200 million. AI also plays a central role in SpaceX’s Starlink and Starshield satellite programs, which rely on automation and machine learning for network management and national security applications.
Musk has previously consolidated his businesses through share-based transactions, including Tesla’s acquisition of SolarCity in 2016 and xAI’s acquisition of X last year. Bloomberg has also claimed that Musk is considering a merger between SpaceX and Tesla in the future.
