Inside Tesla’s ‘tent’-based Model 3 line that set a path to profitability
Tesla attracted more headlines than usual when Elon Musk announced on Twitter that the company is introducing a new Model 3 assembly line inside a sprung structure on the grounds of the Fremont factory. Casually dubbed by Elon Musk as a “tent,” the assembly line, dubbed GA4, played a huge part in pushing Tesla towards profitability in the third quarter.
Tesla’s “tent”-based Model 3 assembly line was featured in Elon Musk’s recent segment on CBS’ 60 Minutes. While speaking with correspondent Leslie Stahl, Musk remarked that the assembly line, which took only three weeks to set up, was responsible for boosting Model 3 production by 50%. That was enough to push the company to reach its self-imposed 5,000 Model 3 per week target in the second quarter.
Elon Musk has noted that Tesla is now at a point when it could produce 5,000 Model 3 per week without any problems. Before the company reached this point, though, it had to pass through a period that Musk personally described as “production hell.” During the second quarter, Tesla struggled to ramp Model 3 output using the vehicle’s two assembly lines inside the Fremont factory itself. When it was evident that this could not be achieved, Tesla did the unexpected — it built a third Model 3 line (GA4) to augment its output.
The construction of the “tent”-based line was lauded by the company’s supporters and criticized heavily by Tesla’s skeptics. Inasmuch as the sprung structure was controversial, though, it worked, and it ultimately helped Tesla address the Model 3’s production problems then. When he announced the promotion of Jerome Guillen as Tesla’s new President of Automotive, Musk stated that GA4 was the brainchild of the longtime problem-solver, who was working as the lead of the Tesla Semi program then. Considering how much GA4 helped Tesla reach its production goals, it is not difficult to speculate that the construction of GA4 was one of the reasons behind Jerome Guillen’s promotion to President of Automotive.
CBS correspondent Leslie Stahl noted during the recent 60 Minutes segment that the “tent”-based Model 3 line, contrary to Elon Musk’s initial plans for a fully-automated car factory, is currently filled with human workers. Musk noted during the segment that “People are way better at dealing with unexpected circumstances than robots,” while sharing a laugh with some workers assembling the Model 3.
Speaking with investors back in 2016, Elon Musk noted that Tesla’s electric car factories will be a “machine that builds the machine.” Musk even shared that the codename for the project is “Alien Dreadnought” — a reference to the hyper-advanced extraterrestrial crafts featured in sci-fi films and literature. The CEO initially estimated the dreadnought to be operational by the end of 2018, though the “production hell” that ensued during the Model 3 ramp forced Elon Musk to admit that over-automation was a mistake. Admitting his miscalculation on Twitter, Musk humbly noted that “humans are underrated.”
If there is one lesson that Tesla learned this year, it is that unorthodox solutions such as its “tent”-based Model 3 line — while a step away from Elon Musk’s original vision — are needed for the company to hit its goals. Using a makeshift production line that’s populated with human workers might not be part of Elon Musk’s “Alien Dreadnought,” but it was exactly what Tesla needed to push towards its manufacturing targets. If any, Tesla’s stellar performance in the third quarter, when it surprised Wall Street and skeptics by posting $6.8 billion in revenue, was made possible in no small part by the “tent”-based Model 3 assembly line.
Ultimately, GA4 could serve as a template for the company’s upcoming electric car production facilities, particularly as Tesla is currently setting the stage for Gigafactory 3, which would produce the Model 3 and Model Y for the local Chinese market. Gigafactory 3 is in an extremely aggressive timetable — one which Wall Street even dubbed as “not feasible.” If Tesla can maintain its open-mindedness and its tendency to adopt out-of-the-box solutions, though, even ambitious projects such as Gigafactory 3 would be more than feasible.

Watch 60 Minutes‘ segment on Tesla’s “tent”-based Model 3 assembly line in the video below.
SpaceX will report second quarter results after the market closes on Tuesday, August 4, marking the first time the company has opened its books to the public since its record IPO in June. Management will host a live audio only webcast at 4:30 p.m. ET, streamed on X, with no dial in option.
The debut carries more weight than a typical first quarter as a public company. Two trading days after the release, on August 6, the first tranche of SpaceX’s lockup expires, freeing roughly 911.5 million insider and employee shares, worth well over $100 billion at current prices and the largest such release in Wall Street history. A second, larger tranche tied to the stock trading 30 percent above its $135 IPO price never triggered, since shares have spent most of July trading below that price.
Wall Street’s models point to revenue near $6.9 billion for the quarter, up sharply from the $4.69 billion SpaceX reported in the first quarter, with a narrower per share loss than the $1.27 posted three months earlier, according to estimates compiled by Motley Fool. Those numbers will be the first look at how SpaceX’s three segments, Starlink, launch and AI, are performing independently.
SpaceX scores another massive Pentagon deal to support military satellites
Investors heading into the call have a specific list of questions. How many net new Starlink subscribers did SpaceX add after ending March with 10.3 million, and is average revenue per user holding up as the service expands into lower income markets. How much of the AI segment’s revenue reflects contract signings with Anthropic, Google and Reflection AI this year, deals that combined could annualize to nearly $28 billion if fully ramped. Whether capital expenditures, which nearly doubled in the AI segment alone between 2024 and 2025, are still accelerating or starting to plateau. And whether management offers any forward guidance at all, something SpaceX has never done publicly.
The report will also land days after Elon Musk publicly denied a Wall Street Journal report describing internal planning to separate Tesla’s China business ahead of a potential Tesla-SpaceX merger. Whether Musk or SpaceX executives address that speculation on the call, even indirectly, maybe something investors will be listening for on Tuesday.
As Teslarati reported after Musk’s own warning to short sellers last week, the CEO has made clear he expects skeptics to be proven wrong over time. Tuesday will be the first chance for the numbers themselves to make that case.

Tesla AI boss reveals how big Optimus is going to get
Tesla’s Optimus chief corrected himself on X, confirming a staggering 10 million robot production target.

Tesla’s Optimus program has a new number attached to it, after Ashok Elluswamy, the executive who has run the humanoid robot program since June 2025, posted a three word correction on X Thursday, “Correction, 10 million robots.”
The line clarifies the long term annual capacity Tesla is building toward its planned second Optimus production line at Gigafactory Texas, a figure Musk has cited repeatedly since last year’s shareholder meeting.
The scale is worth noting, because ten million robots a year would mean Tesla building more units annually than most countries sell in new cars. Tesla has framed this as a second line, not the first. The buildout is happening in two phases: a roughly one million unit per year line inside Tesla’s Fremont factory, installed on the floor space vacated when Model S and Model X production ended earlier this year, and a much larger dedicated facility under construction at Giga Texas that broke ground on its first steel structure in May. That Texas facility is the one Elluswamy’s correction refers to, and is expected to reach volume production sometime in 2027.

Tesla Optimus project fires up as Musk sees production line progress
Elluswamy took over Optimus from Milan Kovac last summer and has spent the months since talking up the program’s trajectory. Elon Musk has also floated the ten million figure at Tesla’s 2025 shareholder meeting.

Ending Model S and Model X production to make room for the first Optimus line was one of the more consequential manufacturing decisions in the company’s recent history, retiring two flagship vehicles in favor of a robot that has yet to enter mass production. Musk has previously estimated per unit production costs at $20,000 to $25,000 once Tesla reaches a million units a year, though he hasn’t said what that cost looks like at ten times the volume.
SpaceX just picked up another $1.6 billion from the Pentagon, with the U.S. Space Force awarding two task orders worth $1.6 billion to fly 18 Falcon 9 missions from Vandenberg Space Force Base in California through the end of 2027. The launches will carry satellites for the Space Based Sensing and Targeting portfolio, a set of programs meant to help the military detect and track airborne threats and relay that information across forces in near real time.
The award falls under National Security Space Launch Phase 3 Lane 1, the Space Force’s faster, commercial style procurement track for missions that do not require the military’s most demanding certification process. It is also the largest single order publicly disclosed under that program so far, and the first task order issued since the Space Force nearly tripled Lane 1’s contract ceiling from $5.6 billion to $17 billion on July 17.
SpaceX to become America’s Military data backbone for missiles, drones, and warfighters
Eric Zarybnisky, the Space Force’s acting portfolio acquisition executive for space access, said the entire process, from identifying the requirement to signing the contract, took about two months, including a month set aside for companies to prepare proposals.
SpaceX is not just launching these satellites. It already holds the contracts to build two of the programs within the same portfolio, $4.16 billion for the Space Based Airborne Moving Target Indicator system and $2.29 billion for the Space Data Network Backbone, which Teslarati covered in May. That means SpaceX is now responsible for both building key pieces of the military’s next generation sensing network and getting them into orbit.
With this latest award, SpaceX’s Pentagon contract total for 2026 alone tops $8 billion, adding to a defense portfolio that already includes the Golden Dome missile defense software group SpaceX joined in April and a string of GPS launches it inherited after ULA’s Vulcan rocket ran into a booster anomaly, which we detailed in March.
Lane 1’s vendor pool technically includes seven companies: SpaceX, ULA, Blue Origin, Rocket Lab, Stoke Space, Impulse Space, and Relativity Space. In practice, SpaceX remains the only provider with the combination of launch cadence, flight proven Falcon 9 hardware, and West Coast infrastructure to support a campaign requiring roughly one Vandenberg launch a month for the next year and a half.

Some lawmakers have flagged the growing concentration of national security launches with one company as a risk worth watching. For now, the Space Force keeps backing SpaceX, with it being the company that shows up ready to launch.
