Tesla Model 3 protects owner from unsafe air even without Bioweapon Defense Mode
Amidst the ongoing threat of the California wildfires, a Tesla Model 3 owner has posted a brief demonstration of the electric sedan’s capability to maintain the air quality inside its cabin, despite the vehicle not being equipped with the Model S and X’s hospital-grade HEPA filter or a dedicated “Bioweapon Defense Mode.”
Elon Musk took to Twitter last week to offer the Model S and Model X as vehicles that can be used to transport people away from the ongoing CA wildfires. The Model S and X are capable of scrubbing the air inside the car, thanks to their large HEPA filters that are fitted with separate acid and alkaline gas neutralization layers. Later social media updates and anecdotes from Model S and X owners driving through the CA area indicate that Bioweapon Defense Mode helped maintain the air quality inside their vehicles.
In a follow-up tweet, Elon Musk noted that the Model 3’s air filtration system is not on the same “hospital-grade” level as that of the Model S and X, since the smaller vehicle does not have enough space to accommodate the HEPA filtration system in Tesla’s two flagship vehicles. This could be seen in the parts catalog for the vehicles, where the Model X HEPA filter was listed as “FILTER, HEPA, MDL X,” while the Model 3’s system was simply listed as “HVAC, CABIN FILTER, M3.”
If a recent video from a Model 3 owner is any indication, though, the electric sedan, even without a hospital-grade HEPA filter or Bioweapon Defense Mode, is still capable of keeping the air inside its cabin clean. The Tesla owner opted to conduct the Model 3’s air filter test in the San Jose area, which has been affected by the smoke from the Camp Fire (Paradise, CA). Prior to the test, the Model 3 owner recorded a PM2.5 level of up to 135 μg/m3 with the vehicle’s windows down.
Upon closing the windows, the Model 3 owner activated the “recycle air” feature and set the fan speed to 5. Within two minutes, the air inside the electric sedan’s cabin improved to less than 50 μg/m3. Keeping the same settings, the air quality inside the vehicle continued to get better, hitting 5 μg/m3 within nine minutes. For a vehicle with a filter that Elon Musk simply described as “good,” the results of the Model 3 owner’s test were quite impressive on their own right.

It should be noted, though, that when the “recycle air” setting was disabled, the air quality inside the cabin dropped. Within five minutes, the air inside the Model 3 was back to the 75 μg/m3 level. These results are in line with Tesla’s announcement through its official Twitter account last week, when the company advised Model 3 owners to “set manual recirculating air and turn up the blower speed” to get the best air quality inside the electric sedan.
Overall, the findings of the Model 3 owner’s test are to be expected, considering Tesla’s intense focus on vehicle and passenger safety. The Model 3, after all, is among the safest vehicles on the road today, thanks to its all-electric design and its standard safety features like forward collision warning systems, dynamic brake support, crash imminent braking, and lane departure warning features. The Model 3’s suite of cameras and sensors, as well as capabilities like Autopilot, make the electric sedan even safer.
Just last month, the National Highway Traffic Safety Administration awarded the Model 3 a flawless 5-Star Safety Rating, just like the Model S and X. Based on the NHTSA’s crash test data, Tesla has noted that the Model 3 now holds the distinction of being the vehicle with the lowest probability of injury among all cars that the agency has tested to date. The Model S and Model X immediately follow the Model 3, standing at second and third place.

SpaceX’s next trillion dollar bet has nothing to do with rockets, Musk tells staff
Elon Musk told SpaceX staff AI revenue will soon dwarf rockets and Starlink combined entirely.
Elon Musk told SpaceX employees this week that artificial intelligence, not rockets, will soon carry the company’s revenue. In a roughly 29 minute internal address posted on SpaceX’s X account on Tuesday, Musk said AI revenue will pass every other line of business at SpaceX “probably in September” and pull further ahead by the fourth quarter.
The numbers he gave are specific. SpaceX currently runs 1.4 gigawatts of AI compute capacity. Musk wants that at 10 gigawatts by the end of 2027, a jump he tied directly to revenue: “if we bring 10GW of AI online by the end of next year, it will be $300 billion to $500 billion a year in revenue.” He called those “big numbers,” which undersells a projection larger than what most countries produce in a year.

Musk went further on where AI fits into SpaceX’s future. “Probably in four or five years, AI will be 99% of the value of SpaceX,” he told staff, adding that digital intelligence would eventually run “a trillion times” ahead of biological intelligence as computing scales. He tied that growth to the company’s founding mission, telling employees “we must win on AI, because the future is overwhelmingly AI and robots,” with the payoff meant to help fund Starship and a Mars program that increasingly runs through Terafab, the joint Tesla, SpaceX and xAI chip plant.

None of this is entirely new territory. SpaceX told investors much the same story during its first earnings call as a public company on August 4, where Musk moved the company’s $1 trillion revenue target up a year to 2030 and said Starlink could someday carry a majority of the world’s internet. What the all hands video adds is a hard deadline and a specific power figure Musk had not given publicly before, along with a franker pitch to his own workforce that AI, not launch cadence, is now the thing SpaceX is betting its future on.
The AI revenue itself is not coming from SpaceX training its own models. It is largely Starlink acting as the network layer for xAI’s workloads, plus SpaceX renting out compute capacity directly, the same approach behind the roughly $16 billion the company spent on AI infrastructure in a single quarter.
Musk closed the video with a pitch aimed at recruiting and retention rather than investors, telling employees that anyone who helps SpaceX win the AI race will eventually get the chance to go to the moon or Mars themselves. Whether SpaceX can turn 1.4 gigawatts into 10 in seventeen months is the more immediate question, and one that will show up in quarterly numbers well before anyone leaves Earth.

Tesla has one big financial question to answer for investors: Morgan Stanley
In a new note to investors on Tuesday, Morgan Stanley analyst Andrew Percoco said that Tesla has one big financial question to answer for investors regarding its Robotaxi rollout, Full Self-Driving software, and Optimus.
Percoco said in the note that, for the most part, investors are still very positive about the direction the company is headed. However, there are some things the firm would like to see, and they have to do with financials.
Tesla (TSLA) Q2 2026 earnings results: miss on EPS, beat on revenue
Tesla bulls are more than convinced that the company’s Full Self-Driving software is proof it can develop physical AI. Financially, however, there are still some questions, especially on elevated spending, which CEO Elon Musk said would occur as the company works to roll out Robotaxi faster and continue developing its Optimus robot.
The latter two are where Tesla will have to prove progress to investors, as Percoco writes that both projects “will require clearer evidence that Robotaxi is scaling and more tangible Optimus proof points to support the ROI on elevated capex.”
Percoco said the second quarter earnings call did not change his long-term thesis of where Tesla is positioned in the AI race, which is out in front. However, there are concerns that weaker gross margins and higher R&D spend will stress financials, and that has “sharpened our (and investors’) focus on measurable progress across Robotaxi and Optimus.”
Additionally, Robotaxi still needs to be proven with more operation in existing cities while maintaining safety but improving how many rides it gives in any given time, he said. For Optimus, Percoco wrote that he is “still looking for evidence beyond commentary around SOP.”
Morgan Stanley put Percoco in charge of covering Tesla after long-time analyst Adam Jonas transitioned to the automotive side.
Currently, Morgan Stanley has a $415 price target on Tesla and a ‘Hold’ rating on the stock. It is trading at around $330 at the time of publication, which was 2:30 P.M. on the East Coast.

SpaceX AI investment gamble will make it a big winner, firm says
SpaceX’s massive investment in AI will make it a big winner, Argus Research said after the company’s successful earnings call last week.
The firm also upgraded shares to a Buy from Hold and set a $160 price target.
SpaceX (NASDAQ: SPCX) is currently recovering from its heavy AI infrastructure investments, as it spent nearly $16 billion in Q2 alone. The company did this primarily by monetizing high-demand GPU compute capacity at a much faster pace than traditional data center economics would suggest.
Company CFO Bret Johnsen said that SpaceX would be able to pay back anything on new deployments within a year.
There are plenty of ways the company can do this:
Leasing excess compute capacity through contracts
SpaceX has already built Colossus and Colossus II, largely for its own model training. However, much of that capacity is already rented out to third parties. It already has major deals with Anthropic, Google, and Reflection AI. These partnerships are adding billions per month to SpaceX’s spreadsheet.
High utilization driven by industry-wide scarcity
The demand for advanced AI training and inference capacity continues to exceed what is available for use. SpaceX can fill new racks quickly after they come online, so the capital deployed converts into revenue with minimal idle time.
Additionally, management and outside observers have described the new compute capital as behaving more like a cost-of-goods-sold than traditional multi-year capex, especially because of this rapid monetization pattern.
Capacity has already scaled from ~0.4 GW a year to 1.4 GW annually by the end of Q2. There are targets of more than 2 GW by year-end.
High incremental margins on the rental business once capacity is online
GPU cloud providers often operate at strong gross margins. SpaceX can monetize capacity that was already partially built or can be added efficiently. This means that incremental EBITDA margins on the rental revenue are usually high. This accelerates cash recovery relative to the gross capital outlay.
Parallel monetization of its own AI software and applications
Beyond pure infrastructure rental, SpaceX also generates revenue from Grok through subscriptions and usage, from X through ads, data, and other related services, enterprise APIs, and the planned integration of the Cursor coding tools acquisition.
These application layers ride on the same compute infrastructure and provide additional high-margin streams that could offset build-out costs. AI-segment revenue overall rose sharply to about $2.6 billion in Q2, according to Motley Fool. This was driven primarily by the infrastructure contracts, but the software side is also partially responsible.
Efficient, large-scale deployment and vertical integration advantages
SpaceX has emphasized the rapid construction of power and cooling infrastructure and favorable cost-per-megawatt economics relative to industry benchmarks in some disclosures.
Combined with its ability to scale capacity aggressively and the fact that many contracts start generating revenue within months of capacity coming online, the effective payback compresses dramatically compared with more conventional multi-year data-center projects.
SpaceX’s dominant near-term recovery path will turn the AI clusters into a hyperscale-style compute rental business for other leading AI companies while still using a portion for internal models.
