Tesla’s word of mouth strategy in focus: Why Elon Musk’s owner-based initiative works
Tesla’s (NASDAQ:TSLA) avoidance of traditional advertising initiatives is one of the most recognizable things about the company, yet it is one that has been questioned several times over the years by Wall Street analysts, investors and even avid fans. Yet, despite these questions, CEO Elon Musk’s answer has always been the same: Tesla does not do traditional advertising. Musk emphasized this point during the last earnings call too, stating that if Tesla would do some form of marketing, it would be strictly informational in nature.
“What we’re seeing is that word of mouth is more than enough to drive our demand in excess of production. We have no plans to advertise at this time. At some point in the future, we may do advertising not in the traditional sense but more to just inform people and make sure they are aware of the product, but not engage in the typical trickery that is commonplace in advertising,” Musk said.
In a conversation with Teslarati, investor and economist @Incentives101 explained that if one looks at Tesla’s word-of-mouth strategy from a mathematical perspective, it would seem that Elon Musk’s stern stance against traditional advertising may actually be well justified. Considering the manner that Tesla has been growing so far, the economist noted that “Elon is probably right. They don’t need advertisement and probably will never need it.” The following sections explains this point.

How Customers Learn About Tesla
There are generally three ways a new customer could learn about Tesla and its products: 1)Elon’s/Tesla goodwill, 2) customers’ own research, or 3) through an existing Tesla owner. Tesla relies heavily on current owners spreading the word and converting people they know into new electric car owners. Most people call this strategy the “Network Effect,” but the economist states that this is a misinterpretation.
“The Network Effect is technically applied to how a product increases its value from a network. The telephone is the most obvious example. One or two telephones in the world are useless, but the more there, are the more useful they become. In a way, you have to treat this like a disease. If you analyze (Tesla’s) strategy, you not only need information to flow. You need the information that changed hands to have an effect. In this case, the purchase of another Tesla. The most similar models to this strategy out there are how diseases spread,” the investor said.
These mathematical models try to predict how a disease will be spread considering different assumptions and variables. Among those variables are the number of susceptible individuals, of infected people and of recovered people, as well as the rate of contagion. For purposes of this illustration, information is equal to a virus and the main variables are the number of people that want to buy a car in that period of time within a target price range or TCO (susceptible individuals), the number of owners at the time (infected people), and the average number of people that an owner would convert in that period of time (contagion). This will be referred to in this article as the ‘T’ variable.

How Tesla spreads
The investor explains this further in the following statement. “The easiest way to understand this is the following. Imagine you’re looking at a decision tree. Each node is a new person with a Tesla in a period of time and how many nodes come out of that person is our ‘T.’ In each period of time that you’d want to measure, there are more assumptions that would need to be made. For example, an owner never ‘recovers’ so not only they ‘infect’ people but they will be contagious in perpetuity.
“Let’s analyze the spectrum of possible solutions. If T>=1, it would mean that information is flowing very efficiently and it will behave exponentially even if the time it takes for an owner to spread enough information to convert someone is relatively high. You need to consider that today, there are more than half a million owners. The faster the person transmits the ‘virus,’ the better,” he said.
There is no way to approximate these variables with the information available to us today. But recently, Tom Randall from Bloomberg released the findings of a study involving 5,000 Model 3 owners. According to the study’s results, 99% of Model 3 owners are pretty much satisfied with the vehicle, and they are willing to recommend the electric car to friends and family. A number of assumptions could be drawn from these results, as per the investor.
“If you consider what would be the worst scenario for Tesla, it would mean a very long time for contagion to spread, with the ‘T’ variable being very close to zero. But with the information provided in the Bloomberg report, there is a very high probability that ‘T’ is not close to zero at all. Instead, there’s a good chance that ‘T’ is probably very close to 1,” the economist said.

Growing Without Traditional Advertising
These assumptions would mean that Tesla can continue to grow without engaging in traditional advertising. Looking at Tesla’s history, we can see that this strategy or combination of strategies have worked. But is there an optimal time to have an information campaign? “It seems that the sooner, the better” the investor explained. “If you look at how this strategy functions, theoretically, the best time to have an information campaign is when they’ll have the least amount of owners and when they’ll increase production dramatically. So in theory this means in the next few months as Tesla continues to hit its stride with Model 3 and begin producing the Model Y, high volume vehicle that Elon Musk expects will outsell the Model S, X, and Model 3 combined. This doesn’t mean they need one, it just means it could be the best time,” he added.
It wouldn’t be accurate to assume that this strategy or combination of strategies is what creates demand. Any company could choose to have either this strategy or spend millions of dollars in advertising and demand wouldn’t necessarily go up or down. “Consumers need information to make decisions — it’s a very important factor — but demand is a function of several factors, particularly consumer preferences. Under perfect information, there is zero doubt demand for Tesla’s will rise as we explained in this note,” the investor noted.
“Tesla’s word-of-mouth strategy helps spread information, but if this product didn’t have a fundamental effect in consumers, it wouldn’t really matter. I’m confident that if banks or media had someone looking at this problem from the consumer side, we would never see a note about alleged ‘demand problems’ again. Tesla has never had a demand problem and data shows that they won’t face one. But they might face an information gap, particularly with how media misinforms consumers,” the economist said.
Disclosure: I have no ownership in shares of TSLA and have no plans to initiate any positions within 72 hours.

OpenAI cites distrust of SpaceX in decision to drop Cursor partnership
OpenAI will cut SpaceX-owned Cursor’s model access in November, citing Musk’s history of broken contracts.
OpenAI, the company behind ChatGPT, announced late Friday that it is ending its partnership with Cursor, cutting off the coding tool’s access to its models on November 12. The move comes two weeks after SpaceX completed its $60 billion acquisition of Cursor’s parent company, Anysphere, folding the popular AI coding assistant into Elon Musk’s growing SpaceXAI division.
In a post on its website, OpenAI said the decision came down to trust, not technology. “We cannot be confident that SpaceX will use our technology within our terms of service, based on our experience with Elon Musk’s companies violating contracts,” the company wrote. OpenAI pointed to two specific incidents: X, now part of SpaceX, allegedly breaking the terms of an existing OpenAI contract after Musk bought Twitter.
That lawsuit is the backdrop for all of this. Musk cofounded OpenAI in 2015, left the board in 2018, and sued Sam Altman and Greg Brockman in 2024, arguing they abandoned the company’s nonprofit mission for profit. A federal jury sided with OpenAI in May, finding Musk waited too long to sue rather than ruling on the merits of his claims. Musk said at the time he would appeal to the Ninth Circuit, calling the outcome a “calendar technicality” rather than a real judgment.
SpaceX’s interest in Cursor predates that verdict by weeks. The company first struck a deal with Cursor in April, securing an option to acquire it for $60 billion or pay $10 billion for joint development work instead. As Teslarati reported at the time, the logic was straightforward: Cursor was paying retail prices to Anthropic and OpenAI, two of its most direct competitors, every time a developer used its product, while SpaceX had idle capacity on its Colossus supercomputer, roughly the equivalent of a million Nvidia H100 GPUs, that Cursor could use to train its own models instead. SpaceX exercised the option in June, days after its own IPO, and the deal closed in mid-August.
Once it closed, Musk moved fast. On an all-hands call with more than 1,000 Cursor employees, he reportedly told staff that SpaceXAI’s Grok was playing catchup in the AI race, unlike Tesla and SpaceX in their own markets, and singled out Anthropic as the company to catch. Cursor CEO Michael Truell now reports directly to Musk inside SpaceXAI.
Losing OpenAI’s models leaves Cursor leaning harder on Anthropic’s Claude, which has its own compute agreement with SpaceX, and on Cursor’s in-house Composer model, the one SpaceX’s compute was supposed to accelerate in the first place. OpenAI framed the November deadline as maximum notice under its contract, and said it wants to “go above and beyond” to help developers through the transition. Whether Anthropic makes the same call is now the open question in AI coding.

Tesla Robotaxi gets a massive upgrade in Nevada
Nevada regulators just approved a massive expansion of Tesla’s robotaxi fleet across the entire county.
Tesla’s robotaxi footprint in Nevada just grew by roughly 500 times in a single regulatory vote.
The Nevada Transportation Authority approved Tesla’s full Autonomous Vehicle Network Company permit on Thursday, clearing the way for the company to deploy up to 5,000 driverless vehicles across Clark County over the next 12 months. The decision came during a four hour general session meeting that Tesla investor Sawyer Merritt watched live and reported on X, noting the vote replaces the interim order that had limited Tesla to just 10 robotaxis on a narrow stretch of the Las Vegas Strip.

That earlier cap, covered here after it surfaced on August 13, came with restrictions that looked stricter than what Tesla runs in Austin: a 45 mph speed ceiling, no airport pickups, and a geofence confined to the Strip corridor. The new approval extends Tesla’s operating authority to all of Clark County, with room to request an even wider geofence across the state.
Tesla representatives at the meeting said they have no intention of putting 5,000 cars on the road right away. Commercial rides are expected to start within 30 days, pending vehicle inspections, insurance filings, and fare approval, the standard steps every robotaxi operator in Nevada has had to clear.
Tesla’s own Robotaxi account replied to the news with a short line, The golden future is upon us.
The timing lines up with Tesla’s broader robotaxi push this month. The company is preparing to open Cybercab rides to the public in Austin as soon as this month, and it opened a sweepstakes for riders to win a seat at the launch event. Tesla filed its original application for a 5,000 vehicle Nevada fleet back in June, a request regulators trimmed to 10 vehicles when they issued the interim order in July. Thursday’s vote effectively grants the number Tesla asked for from the start.
Zoox, the Amazon owned robotaxi operator, has run in Nevada since 2025 and was capped at 100 vehicles before Thursday’s decision. Tesla’s new ceiling puts it well ahead of that comparison on paper, though the company has said its actual fleet size will depend on how quickly FSD v15 rolls out, the software update executives have called the gateway to scaling unsupervised robotaxi operations nationwide.

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.
We made rockets reusable and are rebuilding the internet in space. The next challenge: making life multiplanetary and understanding the true nature of the universe

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.
Elon Musk launches TERAFAB: The $25B Tesla-SpaceXAI chip factory that will rewire the AI industry
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.
