Tesla’s Elon Musk and SEC explains their settlement in joint letter to US judge
Elon Musk and the Securities and Exchange Commission have submitted a joint letter explaining their settlement for a lawsuit resulting from the Tesla CEO’s “funding secured” tweet last August. The letter, which was dated October 11, 2018, comes a week after U.S. District Judge Alison Nathan asked Musk and the SEC to justify their settlement before she approves the deal.
The CEO found himself in hot water late last month after the SEC filed a suit over tweets posted in August, when Musk announced that he was considering taking Tesla private at $420 per share, and that he had “funding secured.” Tesla stock plunged as news of the agency’s lawsuit emerged, dropping more than 13% amidst reports that Musk allegedly rejected a settlement prepared by the SEC. Elon Musk would agree to a settlement with the SEC in the weekend that followed.
Under the terms of the settlement, Musk would be required to step down as Chairman of Tesla’s Board of Directors. The company would also appoint two new independent directors to its board. Elon Musk and Tesla Inc. would have to pay a fine of $20 million each as well, which would, in turn, be distributed to harmed investors under a court-approved process. In a statement last Thursday, Judge Nathan asked Musk and the SEC for a joint letter explaining their settlement, noting that the court needs to make a “minimal determination of whether the agreement is appropriate” before things are finalized.
The SEC noted in the joint letter that it considered multiple factors when it was determining the appropriate penalties for Musk and Tesla, from the gravity of Musk’s alleged violations to the CEO’s lack of monetary gain resulting from his “funding secured” tweet.
“In this case, the SEC considered multiple factors in determining appropriate civil penalties. These included the seriousness of the alleged violations, the market impact caused by the alleged conduct, and Defendants’ financial means, but also countervailing factors such as Defendants’ willingness to settle these actions promptly, Defendants’ apparent lack of pecuniary gain, and the limited temporal scope of the conduct.”
The agency further noted that sanctions against Elon Musk and Tesla are designed to benefit investors by putting additional governance measures in the electric car and energy company. Musk’s representatives, for their part, simply noted in the joint letter that the CEO believes a prompt resolution through the settlement is in the best interests of Tesla’s investors.
“Tesla and Mr. Musk believe that a prompt resolution of these actions through settlement is in the best interests of investors and should be approved.”
The submission of Elon Musk and the SEC’s joint letter comes amidst news that one of Tesla’s largest investors has increased its stake in the company. On Wednesday, it was revealed that T. Rowe Price Group Inc., which owned 11.93 million TSLA shares at the end of Q2 2018, increased its stake in the company in Q3. By the end of September, the firm held 17.4 million TSLA shares, making it the company’s second-largest shareholder, second only to Elon Musk. Another institutional investor, Bailey Gifford, which owns 13.2 million TSLA shares, currently stands as Tesla’s third-largest shareholder.
With Tesla’s Q3 earnings report coming in less than four weeks, T. Rowe Price’s increased stake in the electric car maker could prove to be a strategic investment for the financial firm. Tesla, after all, finished the third quarter on a strong note, delivering and producing a record number of vehicles. Less than two days before the end of the quarter, Musk even sent out a message to Tesla’s employees, urging them to work hard as the company is “very close” to profitability. Since October began, Tesla has also been showing signs that its Model 3 production ramp continues to grow stronger. Teases of an eventual international rollout for the electric car, such as an exhibit in the Paris Motor Show, further suggest that Tesla is steadily gaining its foothold in its efforts to roll out its first mass-market vehicle.

Tesla says its Texas lithium refinery is now operational and unlike anything in North America
Elon Musk separately described the site as both the most advanced and the largest lithium refinery in the United States.
Tesla has confirmed that its Texas lithium refinery is now operational, marking a major milestone for the company’s U.S. battery supply chain. In a newly released video, Tesla staff detailed how the facility converts raw spodumene ore directly into battery-grade lithium hydroxide, making it the first refinery of its kind in North America.
Elon Musk separately described the site as both the most advanced and the largest lithium refinery in the United States.
A first-of-its-kind lithium refining process
In the video, Tesla staff at the Texas lithium refinery near Corpus Christi explained that the facility processes spodumene, a lithium-rich hard-rock ore, directly into battery-grade lithium hydroxide on site. The approach bypasses intermediate refining steps commonly used elsewhere in the industry.
According to the staff, spodumene is processed through kilns and cooling systems before undergoing alkaline leaching, purification, and crystallization. The resulting lithium hydroxide is suitable for use in batteries for energy storage and electric vehicles. Tesla employees noted that the process is simpler and less expensive than traditional refining methods.
Staff at the facility added that the process eliminates hazardous byproducts typically associated with lithium refining. “Our process is more sustainable than traditional methods and eliminates hazardous byproducts, and instead produces a co-product named anhydrite, used in concrete mixes,” an employee noted.
Musk calls the facility the largest lithium refinery in America
The refinery’s development timeline has been very impressive. The project moved from breaking ground in 2023 to integrated plant startup in 2025 by running feasibility studies, design, and construction in parallel. This compressed schedule enabled the fastest time-to-market for a refinery using this type of technology. This 2026, the facility has become operational.
Elon Musk echoed the significance of the project in posts on X, stating that “the largest Lithium refinery in America is now operational.” In a separate comment, Musk described the site as “the most advanced lithium refinery in the world” and emphasized that the facility is “very clean.”
By bringing large-scale lithium hydroxide production online in Texas, Tesla is positioning itself to reduce reliance on foreign refining capacity while supporting its growth in battery and vehicle production. The refinery also complements Tesla’s nascent domestic battery manufacturing efforts, which could very well be a difference maker in the market.

Tesla Optimus V3 gets early third-party feedback, and it’s eye-opening
Jason Calacanis’ remarks, which were shared during a discussion at CES 2026, offered one of the first third-party impressions of the yet-to-be-unveiled robot
Angel investor and entrepreneur Jason Calacanis shared some insights after he got an early look at Tesla’s upcoming Optimus V3. His remarks, which were shared during a discussion at CES 2026, offered one of the first third-party impressions of the yet-to-be-unveiled robot.
Calacanis’ comments were shared publicly on X, and they were quite noteworthy.
The angel investor stated that he visited Tesla’s Optimus lab on a Sunday morning and observed that the place was buzzing with energy. The investor then shared a rare, shocking insight. As per Calacanis, Optimus V3 will be so revolutionary that people will probably not even remember that Tesla used to make cars in the future.
“I don’t want to name drop, but two Sundays ago, I went to Tesla with Elon and I went and visited the Optimus lab. There were a large number of people working on a Sunday at 10 a.m. and I saw Optimus 3. I can tell you now, nobody will remember that Tesla ever made a car,” he noted.
The angel investor also reiterated the primary advantage of Optimus, and how it could effectively change the world.
“They will only remember the Optimus and that he is going to make a billion of those, and it is going to be the most transformative technology product ever made in the history of humanity, because what LLMs are gonna enable those products to do is understand the world and then do things in the world that we don’t want to do. I believe there will be a 1:1 ratio of humans to Optimus, and I think he’s already won,” he said.
While Calacanis’ comments were clearly opinion-driven, they stood out as among the first from a non-Tesla employee about Optimus V3. Considering his reaction to the humanoid robot, perhaps Elon Musk’s predictions for Optimus V3 might not be too far-fetched at all.
Tesla has been careful with its public messaging around Optimus V3’s development stage. Musk has previously stated on X that Optimus V3 has not yet been revealed publicly, clarifying that images and videos of the robot online still show Optimus V2 and V2.5, not the next-generation unit. As for Calacanis’ recent comments, however, Musk responded with a simple “Probably true” in a post on X.

Tesla taps Samsung for 5G modems amid plans of Robotaxi ramp: report
The move signals Tesla’s growing focus on supply-chain diversification and next-generation communications as it prepares to scale its autonomous driving and robotaxi operations.
A report from South Korea has suggested that Samsung Electronics is set to begin supplying 5G automotive modems to Tesla. If accurate, this would mark a major expansion of the two companies’ partnership beyond AI chips and into vehicle connectivity.
The move signals Tesla’s growing focus on supply-chain diversification and next-generation communications as it prepares to scale its autonomous driving and Robotaxi operations.
Samsung’s 5G modem
As per industry sources cited by TheElec, Samsung’s System LSI division has completed development of a dedicated automotive-grade 5G modem for Tesla. The 5G modem is reportedly in its testing phase. Initial supply is expected to begin in the first half of this year, with the first deployments planned for Tesla’s Robotaxi fleet in Texas. A wider rollout to consumer vehicles is expected to follow.
Development of the modem began in early 2024 and it required a separate engineering process from Samsung’s smartphone modems. Automotive modems must meet stricter durability standards, including resistance to extreme temperatures and vibration, along with reliability over a service life exceeding 10 years. Samsung will handle chip design internally, while a partner company would reportedly manage module integration.
The deal represents the first time Samsung has supplied Tesla with a 5G vehicle modem. Tesla has historically relied on Qualcomm for automotive connectivity, but the new agreement suggests that the electric vehicle maker may be putting in some serious effort into diversifying its suppliers as connectivity becomes more critical to autonomous driving.
Deepening Tesla–Samsung ties
The modem supply builds on a rapidly expanding relationship between the two companies. Tesla previously selected Samsung’s foundry business to manufacture its next-generation AI6 chips, a deal valued at more than 22.7 trillion won and announced in mid-2025. Together, the AI chip and 5G modem agreements position Samsung as a key semiconductor partner for Tesla’s future vehicle platforms.
Industry observers have stated that the collaboration aligns with Tesla’s broader effort to reduce reliance on Chinese and Taiwanese suppliers. Geopolitical risk and long-term supply stability are believed to be driving the shift in no small part, particularly as Tesla prepares for large-scale Robotaxi deployment.
Stable, high-speed connectivity is essential for Tesla’s Full Self-Driving system, supporting real-time mapping, fleet management, and continuous software updates. By pairing in-vehicle AI computing with a new 5G modem supplier, Tesla appears to be tightening control over both its hardware stack and its global supply chain.
