SpaceX’s fourth Starship prototype has begun to take shape in Florida
SpaceX’s Florida Starship team appears to have taken the first step towards assembling Starship Mk4, the fourth full-scale prototype of the next-generation spaceship.
Although SpaceX’s Boca Chica, Texas Starship campus is undeniably in the lead with their first prototype, Starship Mk1, it appears that the company’s Florida campus is far ahead of Texas with their second Starship prototype.
At the moment, SpaceX has set up two separate Starship build teams in Florida and Texas with the intention of creating a sort of internal competition to see which group’s Starships are first to flight and first to orbit. For the most part, it’s assumed that this “competition” is less a fight to the finish line than it is an A/B test, a common software development practice in which separate teams pursue different methods of achieving the same goals.
In the likely event that SpaceX is performing a radical form of A/B testing with rocket prototypes, both teams are continuously sharing best-practices and lessons-learned as they work to find the best possible methods for fabricating hardware and assembling Starships. Nevertheless, in A/B testing, fundamentally different approaches also tend to result in development schedules and final products that are unique, even if the end results are similar.
In the context of Starship, this is exactly what can be observed at SpaceX’s Florida and Texas facilities. Similarities abound in the radical method of en plein air manufacturing being implemented, while the Starship Mk1 and Mk2 hardware being built and assembled are also relatively similar, even if they have some distinct characteristics.
For example, it’s been observed that Starship Mk2 has almost certainly been constructed out of steel rings that are significantly taller than those used to assemble Starship Mk1. Taller rings meant that Mk2 needed fewer overall rings to reach the same height as Mk1, a fact that likely contributed to the impressive speed with which SpaceX’s Florida team was able to stack and weld most of Starship Mk2’s aerostructure.
Star(ship)fleet
According to SpaceX CEO Elon Musk, those similarities (and slight differences) are likely to continue for at least several more generations of prototypes. At a September 28th presentation and update on Starship, Musk revealed his opinion that Starship could be ready for its first orbital test flight(s) as few as six months from then – sometime in Q2 2020, give or take. To get there, Musk estimated that at least 5-6 Starship prototypes would need to be built in the interim.
Starship Mk3 will be built in Texas – in fact, the first ‘seamless’ steel ring may have already been fabricated at SpaceX’s Boca Chica facilities. According to Musk, Starship Mk4 will be SpaceX Cocoa’s second prototype. Based on John Winkopp’s October 17th drone overview, it appears that SpaceX’s Florida team has mounted the first steel Starship Mk4 ring atop a new work mount, potentially marking the start of Starship Mk4 assembly.

SpaceX’s Texas team has prepared at least one full-scale sample of a single-weld (‘seamless’) steel ring, perhaps the start of Mk1’s successor, Starship Mk3. Meanwhile, SpaceX Cocoa – seemingly at some kind of impasse with the final integration and assembly of Starship Mk2 – has churned out a huge number of similarly smooth steel rings, to the extent that Teslarati previously (and incorrectly) surmised that the first Super Heavy booster was being fabricated.
During Musk’s September 28th presentation, he effectively confirmed that the almost two-dozen steel rings hanging out on SpaceX’s Cocoa, Florida campus were almost certainly the beginnings of Starship Mk4. However, given the sheer number of rings present (23), the reality is that what could be the entirety of Starship Mk4’s cylindrical tank and thrust structure section is probably sitting outside in Florida, waiting to be stacked. Altogether, those 23 rings could reach a height of more than 40m (130 ft), potentially more than is actually needed for a Starship tank section.

Last but not least, local photographer and spaceflight fan Jon Van Horne captured what looks like a new Starship tank dome in work at SpaceX’s prospective Kennedy Space Center (KSC) build site, known as Roberts Rd. Given that Starship Mk2 already has two domes installed and a third and final dome staged and ready for installation, this fourth dome is very likely the first for Starship Mk4.
In short, SpaceX’s Florida team is probably weeks ahead of Boca Chica in the process of building a second full-scale Starship prototype. Of course, the ultimate winner of this mock competition isn’t Florida or Texas, it’s SpaceX’s Starship program as a whole.

Tesla receives major institutional boost with Nomura’s rising stake
The move makes Tesla Nomura’s 10th-largest holding at about 1% of its entire portfolio.
Tesla (NASDAQ:TSLA) has gained fresh institutional support, with Nomura Asset Management expanding its position in the automaker.
Nomura boosted its Tesla holdings by 4.2%, adding 47,674 shares and bringing its total position to more than 1.17 million shares valued at roughly $373.6 million. The move makes Tesla Nomura’s 10th-largest holding at about 1% of its entire portfolio.
Institutional investors and TSLA
Nomura’s filing was released alongside several other fund updates. Brighton Jones LLC boosted its holdings by 11.8%, as noted in a MarketBeat report, and Revolve Wealth Partners lifted its TSLA position by 21.2%. Bison Wealth increased its Tesla stake by 52.2%, AMG National Trust Bank increased its position in shares of Tesla by 11.8%, and FAS Wealth Partners increased its TSLA holdings by 22.1%. About 66% of all outstanding Tesla shares are now owned by institutional investors.
The buying comes shortly after Tesla reported better-than-expected quarterly earnings, posting $0.50 per share compared with the $0.48 consensus. Revenue reached $28.10 billion, topping Wall Street’s $24.98 billion estimate. Despite the earnings beat, Tesla continues to trade at a steep premium relative to peers, with a market cap hovering around $1.34 trillion and a price-to-earnings ratio near 270.
Recent insider sales
Some Tesla insiders have sold stock as of late. CFO Vaibhav Taneja sold 2,606 shares in early September for just over $918,000, reducing his personal stake by about 21%. Director James R. Murdoch executed a far larger sale, offloading 120,000 shares for roughly $42 million and trimming his holdings by nearly 15%. Over the past three months, Tesla insiders have collectively sold 202,606 shares valued at approximately $75.6 million, as per SEC disclosures.
Tesla is currently entering its next phase of growth, and if it is successful, it could very well become the world’s most valuable company as a result. The company has several high-profile projects expected to be rolled out in the coming years, including Optimus, the humanoid robot, and the Cybercab, an autonomous two-seater with the potential to change the face of roads across the globe.

Tesla rolls out fresh Supercharger pricing strategy to more locations
Live Pricing aimed to resolve some of the shortcomings of the off-peak and on-peak system, aiming to keep prices low and base them on current utilization instead of a set time when prices change.
Tesla has rolled out a fresh Supercharger pricing strategy to more locations, as it confirmed it has added 550 additional sites in the United States to its “Live Pricing” strategy.
Live Pricing for Superchargers launched back in May, and was the company’s latest strategy to keep charging your EV cheap, affordable, and easy to understand.
Tesla has adjusted its pricing strategy at Superchargers several times over the past few years, with the most notable being the 2020 introduction of off-peak and on-peak Supercharging rates.
Live Pricing aimed to resolve some of the shortcomings of the off-peak and on-peak system, aiming to keep prices low and base them on current utilization instead of a set time when prices change.
Tesla explained the program when it launched:
“We are piloting on-peak and off-peak pricing based on live Supercharger utilization rather than estimations. The average price remains unchanged, but this live feedback loop improves accuracy. This corrects off-peak pricing during times of congestion, or on-peak pricing when Superchargers are plentiful. You’ll always see the price before your session begins, and prices do not change mid-session. A small-scale pilot is launching at 10 sites and will expand based on feedback and success.”
The initial rollout only included Superchargers in California, but it was not all of them, only a handful instead. Tesla was attempting to launch it in a very controlled manner by using a Pilot Program that would iron out all the early bugs and potential issues it might run into.
However, the company expanded the program by launching it at an additional 550 sites in California, New Jersey, New York, Florida, and Illinois:
Live pricing expanded to an additional 550 sites in California, New Jersey, New York, Florida and Illinois.
Currently the average price remains the same, peak prices are unchanged and will be paid by fewer sessions.
We’ll keep iterating on getting it right, based on impact and…

The price you pay is locked in when you plug in, so if the Supercharger station you are charging at becomes more crowded and the program bumps up the rates because of high utilization rates, you will still receive the cheaper price that was enabled when you arrived.

Tesla Robotaxi was just spotted in a new state for the first time
The company is still attempting to expand and has explicitly stated that it plans to offer rides in Nevada, Arizona, and Florida in the near future. However, a pair of Robotaxi mules, fitted with LiDAR equipment for ground truth validation, was spotted in a new region for the first time.
Tesla Robotaxi mules were spotted in a new state for the first time as the company plans to expand the ride-sharing service to new areas of the United States in the coming months.
Tesla is offering Robotaxi rides in Austin already, where nobody is present in the driver’s seat except for on freeway routes. In California, Tesla refers to its platform as a ride-hailing suite, and a “Safety Monitor” is present in the driver’s seat at all times, but the vehicle operates on Full Self-Driving.
The company is still attempting to expand and has explicitly stated that it plans to offer rides in Nevada, Arizona, and Florida in the near future. However, a pair of Robotaxi mules, fitted with LiDAR equipment for ground truth validation, was spotted in a new region for the first time.
Over the weekend, Tesla Robotaxi mules were spotted in Enola, Pennsylvania, just about ten minutes from downtown Harrisburg:
🚨 Enola is about 10 minutes from Harrisburg, the State Capitol
Interesting tidbit of information as Tesla is testing Robotaxi close to PA’s legislators https://t.co/5rDlcYrV8w

Enola is situated to the northwest of Harrisburg, Pennsylvania’s State Capitol. Interestingly, you’d expect Tesla to be testing these types of vehicles in other, more populated areas; Philadelphia is about two hours East, and Pittsburgh is about three hours west. State College is about an hour North of Enola.
Looking at the location of where the vehicles were spotted tells an interesting story, as Enola, located right outside of the State Capitol, could be a move to nudge legislators to consider looking at some of the laws that deal with driverless and autonomous vehicle operation.
Pennsylvania’s Act 130 of 2022 and subsequent guidelines permit the testing of driverless vehicles in the Commonwealth, but PennDOT requires a permit from Tesla or any other company that wants to operate a ride-hailing service in PA.
It’s also important to note that the cars could have simply been stopping through, as they were spotted at a Supercharger location along Interstate 81, which spans from Tennessee to New York.
It is not to say the vehicles are testing along the entire route, but likely a segment of it. The fact that they were spotted in Pennsylvania does bode well for Tesla’s expansion efforts moving forward.
