Billionaire resigns CEO role to pay, train for SpaceX’s first crewed Starship Moon launch
Eccentric Japanese billionaire Yusaku Maezawa — known for collecting modern art and founding online fashion retailer Zozo — has stepped down as CEO to free up time and money for his privately-chartered launch around the moon.
Set to launch no earlier than 2023 on what is expected to be SpaceX’s first crewed, circumlunar Starship launch, Maezawa stated in September 2018 that he had arranged to pay SpaceX a huge amount of money (likely several hundred million dollars) for that right. Along with resigning as CEO of Zozo, Maezawa will sell ~85% of his 36% stake to Yahoo Japan, giving the conglomerate a 50.1% ownership stake of Zozo and Maezawa a $2.3 billion cash windfall.
As noted by Business Insider, when asked by a follower if he had any money after an announcement that he would sell off a portion of his extensive art collection in a Sotheby’s auction, Maezawa admitted that he frequently has “no money” because he spends it “right away”, inadvisable but admittedly in-line with his eccentric reputation.
The resignation and sale comes just weeks after SpaceX successfully completed Starhopper’s second and final launch, reaching an altitude of ~150m (500 ft) with the power of a single Raptor engine. During a September 2018 SpaceX press event, Maezawa announced that he had come to an agreement with the company to buy the entirety of Starship’s first crewed mission around the Moon. The billionaire’s motivation: gifting the 8-10 available ‘seats’ to some of the best artists in the world in a project known as dearMoon.
At the same event, SpaceX CEO Elon Musk estimated that the company’s Starship program would cost anwhere from $2B- $10B and confirmed that the bulk of Maezawa’s contributions would go directly towards the rocket’s development costs. Business Insider also quotes Musk as stating that “[Maezawa is] paying a lot of money that would help with the ship and its booster – ultimately paying for the average citizen to travel to other planets.” Alongside Yusaku’s frank Twitter acknowledgment that he may not be the most financially responsible individual and repeated indications that he is extremely proud of Zozo, it’s safe to surmise that the decision to resign was not easily made.
More likely than not, now that SpaceX has completed its Starhopper flight program and is on the verge of its first Starship prototype flight tests, Maezawa simply needs money – and a huge amount of it – to continue fulfilling his contractual commitment to SpaceX. Even if a significant portion of the $2.2-2.3B cash payout he is set to receive goes to settling old debts, the Japanese billionaire should now have more than enough assets to fully fund his SpaceX contract.
At the time, SpaceX had partially completed pieces of the megarocket – then referred to as BFR – in a makeshift development facility at the Port of Los Angeles, pictured above with Maezawa. Since then, SpaceX has renamed the rocket to Starship, drastically redesigned it, and relocated all production operations to Hawthorne, CA, Boca Chica, Texas, and Cocoa, Florida.
Currently, SpaceX is developing twin Starship prototypes at launch and landing test facilities in Boca Chica, Texas (“Mk1”) and in Cocoa, FL (“Mk2”). Musk recently visited the facilities and announced that he is planning to present a technical Starship development update as early as September 28th.
According to an interview posted on WWDJapan.com as part of a September 12th Zozo press conference, Maezawa explained that he believes he made some missteps while serving as Zozo CEO, negatively affecting the company’s bottom line. He believes that more team-oriented business practices and a change of leadership could help to improve the company, which is currently holding its head well above water but still likely to far fall behind its FY2019 performance goals. It’s also hoped that selling an ownership stake in the company will give Yahoo Japan the flexibility to grow Zozo and improve its global reach.
The role of Zozo CEO now goes to Kotaro Sawada who accompanied Maezawa on stage at the announcement event along with Yahoo Japan’s president, Kentaro Kawamata. According to Forbes.com Maezawa stated that “Sawada is the exact opposite of my instinct-based management and adept at management based on logic, like crunching data and testing things out first.”
While Yahoo Japan will look to expand Zozo and the associated online shopping mall Zozotown to compete with other online retailers such as Amazon and Rakuten, Maezawa says that he will turn his attention to achieving his personal goal of a trip around the moon. He mentioned that he plans to fly to space prior to his circumlunar flight in 2023 and will spend much of his time training and learning foreign languages for spaceflight.
He also plans to pursue building another company from the ground up. Whether his next company will be an endeavor focused around space tourism remains to be seen.

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.
