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.

New drone video shows Tesla’s Optimus Factory reaching a turning point
New drone footage shows Tesla’s dedicated Optimus factory steel frame nearing completion at Giga Texas.
Tesla’s dedicated Optimus factory at Gigafactory Texas is closing in on a finished steel frame, according to drone footage posted Thursday afternoon by longtime site observer Joe Tegtmeyer. In the video, Tegtmeyer said structural steel assembly is now about five column grids away from reaching the building’s north perimeter beam, putting the primary skeleton in its final stretch roughly six months after Tesla broke ground on the North Campus site in late March.
The Giga Texas Optimus Factory latest update … construction keeps moving fast!

Tegtmeyer’s footage shows concrete already going in on three upper floors while crews continue laying rebar and pouring grade beam footings at ground level. That kind of parallel work, steel rising at one end of the site while concrete sets at the other, is a scheduling approach Tesla used at the original Giga Texas building and appears to be repeating here to save time before the plant’s targeted 2027 production start.
Teslarati has tracked the building’s progress since Tesla confirmed construction was officially underway in May, when the first steel structure went up on what was then bare, reclaimed land. The facility is part of a more than 5.2 million square foot expansion of Giga Texas’s North Campus that Tesla has said will eventually run nearly the length of the existing vehicle factory, over 4,000 feet, while sitting somewhat narrower. Musk has pegged the long term output target at 10 million Optimus units a year once the line is running at full capacity, a volume that would dwarf the one million unit pilot line Tesla is standing up separately at its Fremont, California factory.
Tesla Giga Texas to feature massive Optimus V4 production line
The Texas facility sits alongside another major buildout on the same campus. Terafab, the joint Tesla and SpaceX chip fabrication plant that will eventually supply the silicon running Optimus units in the field. Housing robot assembly and chip production on the same grounds is a deliberate supply chain decision, cutting down on the shipping and lead time that would otherwise sit between the two.
Tesla has not given an updated timeline beyond its previously stated goal of bringing high volume Optimus production online at the site in the summer of 2027. Fremont’s smaller pilot line began mass producing the current Gen 3 robot in January, with that plant expected to build tens of thousands of units this year primarily to generate the real world data Tesla needs to refine the robot’s software before Giga Texas ramps up. Six months of visible construction progress, tracked almost entirely through Tegtmeyer’s recurring drone flights, gives the clearest outside look yet at how seriously Tesla is treating that 2027 deadline.

Tesla and SpaceX take “Terafab” Trademark fight to Federal Court
Tesla and SpaceX sue a small Illinois firm after cease and desist letters over Terafab.
Tesla and SpaceX are asking a federal judge to rule that their planned Terafab chip factory does not infringe a small Illinois company’s trademark, a request that arrives only after months of quiet negotiation broke down this summer.
The dispute traces to May 18, when Tesla filed three U.S. trademark applications for “Terafab” and “Tesla Terafab,” covering semiconductor chips and related chip making services. TERA-print LLC, a nanotechnology company that has held a federal trademark for “Tera-Fab” since 2021, responded five days later with a cease and desist letter. According to the lawsuit, first reported by Reuters, TERA-print argued that Tesla and SpaceX’s use of “Terafab” would confuse consumers familiar with its own trademark, which covers a desktop photolithography printer sold to researchers for sensor and bioengineering work.
What stands out in the filing is the timing of TERA-print’s own paperwork. One day before sending that cease and desist letter, on May 22, TERA-print applied to expand its existing registration to cover semiconductor materials, silicon chips, nanoelectronic devices and AI design services, categories it had not previously claimed. Tesla and SpaceX call that filing opportunistic in their complaint, noting it arrived two months after Tesla’s public Terafab announcement and just days after Tesla’s own trademark applications went in.
Elon Musk launches TERAFAB: The $25B Tesla-SpaceXAI chip factory that will rewire the AI industry
By June 10, TERA-print was threatening to sue for federal trademark infringement, false designation of origin and unfair competition, the complaint states. Rather than wait to be sued, Tesla, SpaceX and SpaceXAI met with TERA-print six separate times between June and August trying to resolve the dispute directly. Those talks collapsed, and the companies filed for declaratory judgment this week in the U.S. District Court for the Western District of Texas, asking a judge to find that “Terafab” does not infringe TERA-print’s mark before TERA-print can file a claim of its own.
TERA-print isn’t backing down. The company told PCMag it discussed a settlement with Tesla as recently as September 2 and feels misled by what it called Tesla’s professed interest in settling. Its CTO, Andrey Ivankin, said TERA-print holds a Defense Department contract to fabricate semiconductors and partially owns Mattiq Inc., an AI company built on TERA-print’s products, and that the company will vigorously defend its rights.
Tesla and SpaceX argue the overlap is superficial. Terafab is planned as a $16.8 billion complex spanning roughly 100 million square feet at the Grimes County site SpaceX confirmed last month, built to produce chips for Optimus robots, Tesla’s AI computing needs and SpaceX’s orbital data center ambitions, a scale and purpose the companies say no reasonable consumer would confuse with a tabletop lab printer. TERA-print’s product line has stayed focused on lithography tools for biological and sensor research since it registered its mark in 2021.
The trademark fight is the second legal dispute tied to the Terafab project in the past week, following a separate SpaceX suit aimed at keeping company records about the facility out of public view, as KBTX reported. Whether construction proceeds under the Terafab name now depends on a federal judge in Austin.
In a new interview on Wednesday, Tesla uber bull Ron Baron said that anyone looking to buy the company’s stock should do so as soon as they can.
Baron, founder and CEO of Baron Capital and one of Tesla’s most persistent institutional bulls, used a CNBC Squawk Box appearance on Wednesday to deliver a familiar message with fresh urgency: In his opinion, Tesla stock is a buy:
“The time to buy the stock is now. FSD is catching on, and it’s going to be bigger and bigger. 55% of new buyers are buying it (Teslas) with FSD. It’s going to be everywhere. It’s safer.”
The Baron Capital frontman’s case is built around Full Self-Driving. Tesla reported 1.48 million active FSD subscriptions in the second quarter, up 56 percent year over year, and company officials have said roughly 55 percent of new North American deliveries left with a subscription enabled.
Baron framed that attach rate as proof the product is moving from enthusiast extra to default expectation, and as a reason software, not just vehicle volume, should drive the next phase of value.
His conviction on Tesla shares is not theoretical, as Baron Capital made its first Tesla investment in 2014, after years of meetings that began around the 2010 IPO roadshow. The firm later built a large SpaceX position starting in 2017.

Baron said those Musk-led bets have generated about $30 billion of the $71 billion in profits Baron Capital has produced for clients. He put the firm’s current exposure at roughly $25 billion in SpaceX and $5 billion in Tesla. Personally, he described SpaceX as his largest holding, at about $5 billion, with about $1.5 billion in Tesla and additional Tesla exposure through the firm’s funds.
That concentration is also a statement of loyalty. Asked about talk of a SpaceX-Tesla combination, Baron said he had already walked Elon Musk through arguments for and against a deal, then declined to repeat them on air. His public position was simpler: “Whatever you decide is better is what I’m going to support,” he said to Musk.
Baron also said that he picked up the farewell edition of the Model S after Tesla decided to sunset the vehicle earlier this year, calling it his favorite car he’s ever driven.
