SpaceX ‘tops off’ its South Texas Starship prototype with one final steel dome
On September 14th, South Texas SpaceX technicians lifted Starship Mk1’s third and final tank dome and began to attach it atop the prototype’s steel tank section, this time making use of a new method of integration.
This progress comes just two weeks before CEO Elon Musk is expected to present a detailed update on Starship’s newest design iteration. Musk is hopeful that – come his September 28th presentation – Starship Mk1 will be nearly complete and ready for its inaugural flight, a milestone that could come as early as October 13th according to Starship documents filed with the FCC.
This latest installation is likely either the last ring (or nearly so) to be stacked on top of Starship Mk1, paving the way for the eventual attachment of the spacecraft’s conical nose section and the fleshing out of its many internal subsystems and aerodynamic control surfaces. This particular milestone involved the attachment of Starship’s third and final tank bulkhead – in this case, the upper dome of the prototype’s liquid oxygen tank. Excluding hardware that might eventually be installed on the dome itself, this means that Starship Mk1’s tank and engine section has essentially been ‘topped off’.
As previously estimated by the author, this particular tank dome installation – the fifth completed by SpaceX’s Mk1 and Mk2 Starship teams – was done in a manner thus far unique. All previous installations have seen SpaceX technicians lower the domes – completed aside from one vertical weld for flexibility – inside the Starship’s cylindrical tank section. The steel domes are then carefully spot-welded to the side of the tank in their proper place – all while being supported by a large crane – before technicians can complete a seamless ring weld around their entire circumference.
This time around, SpaceX welded the upper tank dome to its companion ring section while both elements were still staged on the ground. Once the dome was completely welded to the steel ring and a dome cap was installed to seal off the top, the ring segment was craned atop Starhip Mk1 on September 14th. It’s possible that this was planned all along for each Starship’s third and final tank dome, but the way CEO Elon Musk has previously described SpaceX’s semi-competitive Mk1 and Mk2 builds suggests that it may instead be a new assembly strategy that evolved in just the last month or two.
Instead of having to do the work of fitting, attaching, and ring-welding the bulkhead to Starship’s tank section 50-100 feet above ground, with all the associated rigging, scaffolding, and challenges such a work environment demands, technicians were able to do the majority of that work at ground-level. This method seems to offload the added challenge of dome installation to the vertical ring installation process, effectively merging the two processes into one much simpler (and safer) feat.
The fact that Starship Mk1’s tank section has now been capped (aside from several small access ports) indicates that all large, plumbing-related components have been installed inside the steel prototype. Up next for Starship Mk1 is the installation of its landing legs/fins/wings (at least two of which have already arrived on-site), canards, and a variety of smaller additions like valves, thrusters, ground connection points, and much more.

Cantor Fitzgerald reaffirms bullish view on Tesla after record Q3 deliveries
The firm reiterated its Overweight rating and $355 price target.

Cantor Fitzgerald is maintaining its bullish outlook on Tesla (NASDAQ:TSLA) following the company’s record-breaking third quarter of 2025.
The firm reiterated its Overweight rating and $355 price target, citing strong delivery results driven by a rush of consumer purchases ahead of the end of the federal tax credit on September 30.
On Tesla’s vehicle deliveries in Q3 2025
During the third quarter of 2025, Tesla delivered a total of 497,099 vehicles, significantly beating analyst expectations of 443,079 vehicles. As per Cantor Fitzgerald, this was likely affected by customers rushing at the end of Q3 to purchase an EV due to the end of the federal tax credit, as noted in an Investing.com report.
“On 10/2, TSLA pre-announced that it delivered 497,099 vehicles in 3Q25 (its highest quarterly delivery in company history), significantly above Company consensus of 443,079, and above 384,122 in 2Q25. This was due primarily to a ‘push forward effect’ from consumers who rushed to purchase or lease EVs ahead of the $7,500 EV tax credit expiring on 9/30,” the firm wrote in its note.
A bright spot in Tesla Energy
Cantor Fitzgerald also highlighted that while Tesla’s full-year production and deliveries would likely fall short of 2024’s 1.8 million total, Tesla’s energy storage business remains a bright spot in the company’s results.
“Tesla also announced that it had deployed 12.5 GWh of energy storage products in 3Q25, its highest in company history vs. our estimate/Visible Alpha consensus of 11.5/10.9 GWh (and vs. ~6.9 GWh in 3Q24). Tesla’s Energy Storage has now deployed more products YTD than all of last year, which is encouraging. We expect Energy Storage revenue to surpass $12B this year, and to account for ~15% of total revenue,” the firm stated.
Tesla’s strong Q3 results have helped lift its market capitalization to $1.47 trillion as of writing. The company also teased a new product reveal on X set for October 7, which the firm stated could serve as another near-term catalyst.

Elon Musk’s xAI becomes Memphis’ 2nd largest taxpayer in just one year: report
Elon Musk’s artificial intelligence startup, xAI, is reshaping Memphis’s economic landscape.

Elon Musk’s artificial intelligence startup, xAI, is reshaping Memphis’s economic landscape. In just twelve months, the company has become the city and county’s second largest taxpayer.
The update was related in a report from The Wall Street Journal.
Memphis’ second-largest taxpayer
xAI is currently transforming a defunct Mississippi power plant into a crucial hub for AI, supplying electricity to its Colossus supercomputer cluster and its successor, Colossus 2. Together, the Colossi supercomputers will host more than half a million Nvidia chips that would be used for the development and improvement of Grok, xAI’s large language model.
The buildout has injected billions into the region, making xAI one of Memphis’s most significant private investors and a symbol of the city’s high-tech aspirations. Bill Dunavant III, a Memphis businessman who sits on the board of directors of the city’s chamber of commerce, highlighted xAI’s contribution to the city’s economy in a comment to the WSJ.
“In one year, xAI has become the second largest taxpayer in the city and county after FedEx,” he said. A spokesman for the Greater Memphis Chamber of Commerce has also stated that xAI has demonstrated “substantial economic commitment to our region, without any tax incentives.”
Not without controversy
Despite the economic boost, xAI’s footprint has drawn scrutiny. The company’s natural-gas-powered turbines are expected to consume a substantial amount of water and electricity. Critics have also expressed worries about pollution and increased utility costs, though others see Musk’s wastewater recycling plans and cleanup initiatives as meaningful offsets.
As per the WSJ, xAI’s positioning in the market may be quite different than what Musk is typically used to, considering that the CEO tends to become a first mover in key industries, such as the EV segment with Tesla and private spaceflight with SpaceX. With xAI, however, he is catching up to competitors, the most notable of which is a company he co-founded, OpenAI, and its ubiquitous large language model, ChatGPT.

Tesla all but confirms that affordable Model Y is coming Tuesday
It does appear that October 7 would be the date when the world sees Tesla’s actual idea of what an affordable vehicle would be like.

Tesla has released a cryptic teaser of a product that would be announced on Tuesday, October 7, 2025. Based on the company’s hint, it does appear that the product would be the affordable Model Y that has been spotted doing road tests across the country over the past months.
Affordable Model Y sightings
Last week, news emerged that a number of key Tesla influencers visited Gigafactory Texas for a private event. These included veteran Tesla YouTubers, car reviewers, influencers on X, and even a teardown expert who provided the initial insights on how to improve the original Model 3 sedan. At the same time, an uncovered unit of the apparent affordable Model Y was posted online. The vehicle was reportedly sighted close to Giga Texas.
The new Model Y variant had some notable changes from the standard Model Y. Its fascia seemed inspired by the Model 3 sedan instead of the Cybertruck, and its roof seemed blacked out. Overall, it looked like a simpler Model Y designed to be offered at an affordable price.
The weekend teasers
Teasers about an upcoming product were posted by Tesla’s official account on social media platform X, though the electric vehicle maker made it a point to keep things very vague. Initially, a closeup video of what appeared to be an aero wheel was posted, though it was vague enough that some speculated that it could be Elon Musk’s long-announced HVAC system instead.
On Sunday, another teaser video was posted featuring the headlights of a new car. This brought speculations that the new Roadster might finally be announced. Inasmuch as a new Roadster unveiling would be exciting, however, it was evident that the headlights in the new teaser were a match to the uncovered affordable Model Y unit that was spotted close to Giga Texas a few days ago. With this in mind, it does appear that October 7 would be the date when the world sees Tesla’s actual idea of what an affordable vehicle would be like.
