Tesla flyover captures Model 3 rolling off Fremont’s giant tent assembly line
A recent flyover of Tesla’s Fremont factory has captured a rare footage of a freshly-built Model 3 rolling off GA4, the company’s newest general assembly line set up in a massive sprung structure. Located in the northeast end of Tesla’s main factory, the giant tent is currently seeing a flurry of activity as employees assemble the compact electric car.
The short clip of the flyover was shared by NBC host Raj Mathai, who noted that the overflow production line was added as a means to help Tesla achieve its self-imposed goal of producing 5,000 Model 3 per week by the end of the second quarter. Elon Musk, who has expressed enthusiasm about the sprung structure, responded to the video, stating that GA4 is working and that it has a “slightly higher quality” than more traditional assembly lines.

The flyover video revealed a number of interesting new scenes, the most notable of which is a freshly assembled silver Model 3 being driven off the end of GA4. Cars that are being constructed, as well as rows of finished vehicles, were also featured in NBC‘s brief clip.
Tesla’s sprung structure is massive, spanning the size of two football fields. Considering its unorthodox nature, GA4 has attracted its own fair share of critics, such as financial analyst Max Warburton from Sanford C. Bernstein & Co., who dubbed the assembly line as “insanity.” In a statement to KTVU News, however, Dr. Fred Barez, director of San Jose State’s Electric Vehicle Technology, stated that Telsa’s giant tent is actually not that unusual, since it’s being used throughout the world, especially in the field of aviation.
“It is not unusual because he understands the problems that he’s facing. He comes up with outside the box solutions. It is definitely in the right direction because this tent facility is going to double the capacity. It’s going to at least improve that capacity,” Dr. Barez said.
As the end of June approaches, Tesla stock (NASDAQ:TSLA) has become a battleground between bulls and short-sellers, with Goldman Sachs analyst David Tamberrino stating that Tesla would likely only deliver 22,000 units of the Model 3 during the second quarter, despite production likely to hit 5,000 vehicles per week in the final week of Q2 2018. It should be noted, however, that earlier this year, Tamberrino also issued a report stating that Tesla would only manufacture 1,500 Model 3 per week for the second quarter, making his current bearish expectations slightly optimistic by his own standards.
Pierre Ferragu of New Street Research, however, has a more optimistic outlook. In a recent statement to The Street, the Tesla bull noted that Tesla is still on track to profitability on Q3 or Q4 2018, regardless of whether the company achieves its Model 3 production targets this second quarter or not.
“You should not look at how many cars are produced. Instead, you should look at how much money each vehicle is bringing in, and as Tesla ramps production their free cash flow will improve dramatically. The long-term, five- to seven-year trajectory is the real story of Tesla,” Ferragu said.
Tesla stock continues to hold its position in the market, with shares of the electric car maker standing its ground after a steep 6% plunge last week. As of Wednesday’s intraday, Tesla stock is trading up 1.37% at $346.70 per share.

Elon Musk handed Grok something no other AI company can get their hands on
Elon Musk says SpaceX will feed engineering data into Grok’s next model, avoiding restricted material.
Elon Musk said Tuesday that SpaceX will feed its internal engineering data into the next major training run for Grok, the AI model now folded into SpaceX following February’s merger. In a post on X, Musk wrote that SpaceX’s “massive corpus of world-class engineering data,” excluding anything restricted under U.S. arms export law, will be added during supplemental training of what he called the “2T run,” a reference to a roughly two trillion parameter model that would nearly double the parameters behind the latest Grok 4.5 that’s rolling out.

This will dramatically improve Grok’s engineering capabilities. https://t.co/BbQEViFByn

The excluded material that Musk is referring to would fall under the International Traffic in Arms Regulations (ITAR), which restricts export of technical data tied to defense and space hardware. That likely rules out propulsion specifics for Merlin and Raptor engines along with guidance and control details for SpaceX’s launch vehicles, but leaves manufacturing knowledge, materials science, and Starlink hardware design on the table.
The announcement extends a pattern that has been building since SpaceX’s Nasdaq debut in June, when the company went public with Grok and xAI’s Colossus supercomputer folded into the pitch to investors.
Days after that listing, SpaceX closed its $60 billion all stock acquisition of coding startup Cursor, giving xAI both enterprise software distribution and a stream of real world developer data to train on. Grok 4.5 launched July 8 running partly on that Cursor training data, with Musk describing it as roughly comparable to Anthropic’s Opus 4.7 but faster and cheaper to run.
Feeding SpaceX’s own engineering data into the next AI model follows the same logic Musk has applied across xAI’s sister companies. Tesla supplies real world driving data and manufacturing expertise, X supplies conversational data, and now SpaceX supplies aerospace engineering data built up since 2002.
Musk did not give a release date for the upcoming AI model, referred to elsewhere as Grok 4.6. He has said the two trillion parameter run is in its final training phase and expected to wrap this week.
In a pointed message on X, Elon Musk warned that firms maintaining significant short positions in SpaceX over time face “very low” survival probability.
The statement comes amid post-IPO volatility for the rocket company, now trading under the ticker $SPCX.

Five weeks after what was described as the largest IPO in history, the stock had fallen roughly 30% from its peak above $2.6 trillion, briefly surpassing Microsoft and Amazon in market value. Short sellers celebrated gains of about $8.7 billion, but Musk’s reply underscores his long-term conviction.
The warning directly echoes a detailed bullish analysis arguing that Starship’s cost reductions could unlock a multi-trillion-dollar space economy. Projects ranging from solar power beamed from orbit and asteroid mining to orbital data centers and Mars terraforming were projected to create over $100 trillion in new market capitalization.
In this vision, SpaceX acts as the essential infrastructure provider, akin to AWS for cloud computing, capturing monopoly-like revenues from launches, crew transport, and data traffic across a rapidly expanding frontier.
This is far from the first time Musk has targeted short sellers. With Tesla, he has repeatedly framed persistent bears as destined for major losses. In July 2024, Musk declared that once Tesla achieves full autonomy and volume production of Optimus robots, “anyone still holding a short position will be obliterated. Even Gates,” referencing Microsoft co-founder Bill Gates’ reported short bets.

Earlier, in 2018, he taunted shorts that they had “about three weeks before their short position explodes,” a remark followed by sharp stock gains. Musk has also called short selling “value destroying” and once suggested it “should be illegal,” viewing it as betting against innovation and progress.
Critics often dismiss Musk’s optimism as hype, especially when near-term metrics like quarterly deliveries or stock fluctuations disappoint.
Yet his pattern remains consistent: framing short positions against his companies as fundamentally misjudging exponential technological leaps. For SpaceX shorts, the message is clear: betting against multi-planetary ambitions and the infrastructure monopoly they enable carries existential risk for the firms involved.
As Musk and supporters see it, the space economy’s upside dwarfs Earth-bound valuation models, making today’s dips temporary in a decades-long ascent.

SpaceX Starship Flight 13 aborted at Zero and Musk just told us what broke
Four Raptor engines failed to ignite at T-zero, forcing SpaceX to scrub Starship Flight 13 Thursday.
SpaceX scrubbed the Starship Flight 13 launch attempt Thursday evening at the last possible moment, after four of the Super Heavy booster’s 33 Raptor 3 engines failed to ignite during the startup sequence. The 90-minute window had opened at 6:45 p.m. EDT from Starbase in Boca Chica, Texas, and the countdown had proceeded without issue all day, with more than 11.5 million pounds of liquid methane and liquid oxygen being fully loaded into the rocket before the automated abort triggered. SpaceX’s launch directors posted on X, “Standing down from today’s flight test attempt,” and shut down the livestream shortly after.
Musk confirmed the root cause within hours. “Some of the engines didn’t start, triggering an automatic launch abort,” he wrote on X. “To be confident of a good flight, 2 Raptors will be removed and replaced. Most probable launch timing is early next week.” SpaceX engineers began draining propellant tanks immediately and Booster 20 was rolled back to its hangar for inspection.
The timing adds a layer of significance that did not exist during any of the previous 12 Starship flights. This is the first time SpaceX has attempted to launch Starship since the company made its stock market debut in June, listing under ticker SPCX at $135 per share. Public investors are now watching every Starship outcome in real time, and a last-second abort carries more visibility than it would have six months ago.
Flight 13 was designed to be one of the most consequential tests in the program’s history. It was set to carry 20 Starlink V3 satellites, the first operational payload Starship has ever attempted to deploy. Six of those satellites carried external cameras to photograph Starship’s heat shield from the outside during flight, which would act as a self-inspection approach SpaceX has never attempted before. The mission also needed to complete a Raptor engine relight in space, a step SpaceX skipped on Flight 12 in May after losing an engine during ascent. That Flight 12 booster also flipped 90 degrees off course during its boostback burn when five engines failed to reignite.
SpaceX has not announced an official next launch date. Musk’s “early next week” window points to July 21 or 22 at the earliest, pending the engine swap and a return to the pad.
