Tesla’s $218M acquisition of ultracapacitor firm opens doors to energy breakthroughs
Just a few days after Tesla (NASDAQ:TSLA) posted its second consecutive profitable quarter, the company has stated that it plans to acquire energy technology firm Maxwell Technologies, a California-based maker of ultracapacitors and batteries. The deal will reportedly be an all-stock transaction valued at around $218 million, with Tesla buying Maxwell’s 45.9 million shares for $4.75 a share — a 55% premium over the energy company’s closing price of $3.07 a share last Friday.
Maxwell Technologies specializes in the development of ultracapacitors. Prior to its acquisition by Tesla, Maxwell had been working on developing dry electrode technologies that could be utilized to create ultracapacitors that can store large amounts of electrical charge without losing energy — a breakthrough for electric cars and energy storage devices. Ultracapacitors are lauded by several industry watchers as a possible alternative to today’s batteries, considering their potential to be safer and more reliable.
In a statement to The Street, Maxwell Technologies CEO Dr. Franz Fink expressed his optimism over the planned acquisition. The CEO further pointed out that Tesla and Maxwell actually share a common goal — to build a more sustainable future.

“We are very excited with today’s announcement that Tesla has agreed to acquire Maxwell. Tesla is a well-respected and world-class innovator that shares a common goal of building a more sustainable future. We believe this transaction is in the best interests of Maxwell stockholders and offers investors the opportunity to participate in Tesla’s mission of accelerating the advent of sustainable transport and energy,” he said.
Dr. Fink’s statement was echoed by Tesla. In a statement to CNBC, the electric car maker noted that it is always on the lookout for possible acquisitions that would allow it to pursue its mission. “We are always looking for potential acquisitions that make sense for the business and support Tesla’s mission to accelerate the world’s transition to sustainable energy,” Tesla noted in a statement sent to the publication.
What is particularly interesting about Maxwell’s acquisition is that Elon Musk himself has expressed his support for ultracapacitor technologies in the past. Back in 2013, Musk mentioned on a Twitter post that he is a “big fan of ultracapacitors,” even adding that he was planning on conducting his Ph.D. research on ultracapacitors during his short stint at Stanford University. That said, Musk also noted that there needs to be a breakthrough in energy density for ultracapacitors to truly make a difference.
@yes_andre I'm a big fan of ultracapacitors. Was going to do my PhD at Stanford on them. But we need a breakthrough in energy density…

Tesla’s acquisition of Maxwell Technologies marks the electric car maker’s fifth acquisition to date. Prior to Maxwell, Tesla acquired Riviera Tool LLC, a manufacturer of stamping die systems used to form sheet metal parts in May 2015; SolarCity, a provider of solar energy services to homeowners, businesses, government, and non-profit organizations in June 2016; Grohmann Engineering, a firm that makes Tesla’s robots for production in November 2016; and Perbix, a maker of highly automated manufacturing equipment in November 2017.
Tesla and Maxwell Technologies expect to close the acquisition deal sometime in the second quarter of 2019, pending customary closing conditions. So far, the deal appears to be well received by Maxwell’s investors, with the company’s stock (NASDAQ: MXWL) trading up 50.49% as of writing. The reaction of the market to Tesla appears to be more muted, with TSLA stock trading down 0.52% as of writing.
Disclosure: I have no ownership in shares of TSLA and have no plans to initiate any positions within 72 hours.

Tesla Optimus Gen 3 shows off a cleaner, factory-ready design in new app discovery
Renders hidden inside Tesla’s Android app show Optimus Gen 3’s design before any official reveal.
Tesla may have accidentally given a first look at its newest Optimus Gen 3 humanoid robot when photos were found in the Tesla smartphone app.
Design files tucked inside a recent Android version of the Tesla app appear to show the third generation humanoid robot next to the older Gen 2.5 prototype. The assets were extracted from the app package by Tesla community member @wholemars, who posted the renders on X late Tuesday night before deleting them. The Tesla Newswire reshared the side by side comparison on Wednesday, and the images have circulated widely since.

Tesla Optimus Gen 2.5 vs Gen 3 comparison via @WholeMars on X
The files are labeled “gen3” and were built as models for Tesla app’s own interface, as validated directly by Grok to be official.
The comparison shows a robot that looks built for a factory line rather than a lab bench. Gen 2.5’s exposed mechanical linkages and gold plating on the knees and shins are gone. In their place, Gen 3 uses matte black fairings on the lower legs, paired with a more contoured champagne gold body. Flexible covers now seal the joint where the torso meets the upper thighs, keeping bearings and moving parts sealed from debris and unnecessary contact.
The body panels fit more tightly, and the hands, which Tesla has said carry 22 degrees of freedom, look far more refined than those on earlier units.
This most recent leak fills a gap Tesla has left open for most of the year. Elon Musk said on March 31 that Optimus 3 was walking around but needed “some finishing touches” before it could be shown, a delay Teslarati covered when Tesla missed its first quarter reveal target. Musk later said Tesla would hold the design back until closer to production, partly to keep competitors from copying it. No reveal date has been announced.
The app itself has been preparing for Optimus for months. In July, code in the Tesla app pointed to a dedicated robot phone key, a consent screen for collecting video and spatial data while Optimus works inside a home, and an alert system for low battery and mechanical faults. Finished 3D models of Gen 3 suggest the interface owners will eventually use is moving past placeholder code toward something Tesla intends to ship.
Manufacturing is moving in parallel. Tesla tore out the original Model S and Model X lines at Fremont this summer to make room for Optimus production, with a planned capacity of one million robots a year. At Giga Texas, the steel frame of a dedicated Optimus factory is nearing completion ahead of a targeted 2027 start, with Musk pointing to an eventual output of 10 million units annually.

X changed how everyone gets paid, and this lawsuit shows why
X sued a Bitcoin account network over fake payouts as its creator pay model shifts
Elon Musk’s X has taken a Bitcoin-focused engagement ring to court, and the case doubles as a receipt for how differently the platform pays creators today. The company filed suit in the High Court of England and Wales against Vivek Kumar Sen and Zamyang Sherpa, alleging the pair ran six accounts, including @Vivek4real_, @Bitcoin_Teddy and @TrendingBitcoin, as one coordinated operation to fake the kind of engagement that used to translate directly into money.
According to the filing, first reported by Gizmodo, the accounts posted near identical “BREAKING” crypto headlines seconds apart, in one case 11 seconds, then had three more handles like, reply to and repost the material to manufacture what X called “a false appearance of genuine, human communication and interaction.” X says the scheme pulled in at least £207,384, about $278,000, and pegs its own investigation and remediation costs at another £75,000. The accounts were suspended August 18. X general counsel James Burnham announced the case on X last weekend, writing that the company “will act forcefully to protect our platform and the earnings of genuine creators.” Musk’s own reaction, posted shortly after, was three words: “Don’t mess with 𝕏.”
Don’t mess with 𝕏 https://t.co/HSmd5hL6aQ

The timing lines up with a a recent update to how X pays its creators. The program these accounts allegedly gamed, Creator Revenue Sharing, launched in mid 2023 and paid out based on how much a post got engaged with. Originality was never part of the formula, which is exactly how the platform ended up flooded with recycled clips, copy pasted “BREAKING” posts and replies engineered purely to farm reactions from paying subscribers.
X tried patching the model more than once, including an April cut to aggregator payouts and a March regional weighting change that Musk personally paused hours after it was announced. X retired Creator Revenue Sharing for good on September 7 and opened its replacement, Original Content Rewards, the next day.
Today, we’re launching Original Content Rewards.
The reality is that Revenue Sharing had reached a point where its incentives were misaligned. Creators should be focused on bringing net new content to the platform instead of maximizing payouts. We could have kept adding more… pic.twitter.com/VJIxqlPrjm

The new math is stricter. Payouts now come only from qualified impressions, meaning unique Home Timeline views from Premium subscribers where at least half the post is visible, and replies no longer count toward eligibility at all. Copied posts, reuploaded media and reposts without meaningful changes are explicitly excluded. Allegra Jacchia, senior product manager for Creators at SpaceXAI, which now runs X’s product and AI work following xAI’s acquisition of the platform, put it bluntly, saying the goal is to reward creators who bring original ideas and perspective, “not those who have become best at gaming the system.”
Read that way, the lawsuit isn’t really about six crypto accounts. It’s X putting a dollar figure on what the old incentive structure cost, then suing to collect it right as the new one goes live. For live updates on how the case and the new rewards program shake out, follow @Teslarati on X.

Why automakers keep turning down Elon Musk’s Tesla Full Self-Driving offer
Elon Musk confirms no automaker has ever accepted Tesla’s offer to license Full Self-Driving software.
Elon Musk gave a brief answer on X Monday that confirmed that Tesla’s standing offer to license Full Self-Driving to other automakers still has zero takers. Sawyer Merritt wrote that “Tesla has for years openly invited other automakers to license FSD. None of them have accepted,” responding to a prediction from Boom Supersonic founder Blake Scholl that Tesla would eventually open FSD the way it opened its Supercharger network to rival brands. Musk’s reply to Merritt was one word: “Exactly.”
It is not the first time Musk has made this point. He said something similar in November, when he called legacy automakers reluctance to adopt FSD “crazy,” and Tesla has floated the offer publicly since at least 2021. Scholl’s prediction touches on something real. Once NACS became the de facto charging standard, adoption from Ford, GM, Rivian and others followed within about a year. FSD licensing was supposed to work the same way once Tesla built enough of a lead that switching made sense for everyone.

The case for licensing now is stronger than it was two years ago. Waymo and Zoox are logging hundreds of thousands of unsupervised autonomous miles, along with Tesla’s own Robotaxi fleet. Every automaker still selling driver assist systems that lag FSD has given the robotaxi conversation to Tesla, Waymo and Zoox by default. Licensing FSD would let a GM or a Ford compete on the same field without spending a decade and billions of dollars building a stack from scratch, the same argument Tesla made when it opened the Supercharger network to bring more EVs onto its chargers.
But FSD is not a connector standard. As one reply to Musk’s post pointed out, licensing FSD is not a software license the way NACS was a plug spec. It requires adopting Tesla’s eight camera layout and its onboard compute architecture, meaning a licensee’s cars would effectively become Tesla hardware wearing someone else’s badge. That is the visible obstacle. The less visible one is data. A licensed FSD stack would report back the same telemetry Tesla collects from its own fleet, giving Tesla a continuous read on how a competitor’s cars are actually driven, where they struggle, and how often drivers intervene. For an automaker trying to build its own autonomy program, or simply trying to keep its build quality and safety record private, handing Tesla that visibility could be a bigger cost than the hardware bill. It is the reason the Supercharger comparison only goes so far. Opening a charging plug cost Tesla very little. Opening FSD would cost a rival something it cannot get back.
