Tesla’s (NASDAQ:TSLA) first-quarter earnings call comes on the heels of an impressive quarter that saw the electric car maker post $10.389 billion in revenue and non-GAAP earnings per share of $0.93, beating Wall Street’s expectations. With these results, Tesla has now maintained its profitability for seven straight consecutive quarters.

As revealed in the company’s Q1 2021 Update Letter, the company hit some notable milestones in the first quarter. The Model 3 became the world’s best-selling premium sedan, electric or otherwise. The Model Y is also showing a lot of potential, with the vehicle’s production ramp going well in Gigafactory Shanghai. Deliveries for the Model S Plaid are expected shortly as well, and the Tesla Semi, a Class 8 truck that has seen delays, is now poised for a 2021 release.

The following are live updates from Tesla’s Q1 2021 earnings call. I will be updating this article in real-time, so please keep refreshing the page to view the latest updates on this story. The first entry starts at the bottom of the page.

15:41 PT – And that wraps up Tesla’s Q1 2021 earnings call! Overall, Elon Musk and team seemed to be a bit cautious this time around, with timeframes for projects like the 4680 cells being conservative. Tesla also did not provide a specific forecast for 2021’s vehicle deliveries. But considering the ongoing supply challenges, this may not be a bad strategy at all.

Anyway, thanks for staying with us for another live blog! These are always fun. Until the next time!

15:40 PT – Dan Levy from Credit Suisse asked about Tesla and its ongoing cost reductions. Tesla notes that building cars is a complex process, though if one were to look at the advancements in the production of the company’s vehicles like the Model Y, there are a lot of innovations happening there, which should improve COGS.

When asked about Fremont vs the Gigafactories, the analyst asked about how Tesla’s new capacity would differ from the previous NUMMI plant. Musk notes that Tesla does not talk much about future product developments. “We’ll get there. We’ll provide it later,” Musk said.

15:34 PT – Rod Lache of Wolfe Research LLC asks about the FSD rollout, such as the subscription model and its impact. Kirkhorn noted that Tesla is working on rolling out FSD subscriptions, though there are some aspects of the service that still need work. “We’re hoping to get this launch pretty soon, and see what the response is to it,” he said.

15:33 PT – Ferragu asks a follow up about Tesla’s energy business. According to Musk, Tesla has comparable margins in energy and vehicles though it should be noted that the company’s EV business is more mature than the energy segment. Powerwall is mature, however, so the margins there are pretty good. “We have a clear runway for improving the cost of the Megapack,” Musk said.

15:30 PT – Analyst questions start. First up is New Street Research’s Pierre Ferragu. He asks about the 4680 battery line (YES!). He asks about capacity, as well as where the company stands in its ramp.

Musk notes that Tesla has a small pilot plant for the 4680 cells with a 10 GWh per year capacity. “We’re not yet at a point where we think the cells are reliable enough to be put in cars. We think we’re close to that point. We’ve already ordered the equipment for battery production in Berlin and Austin as well. We’re down to the nitty gritty on this. I’m confident that we’d achieve volume production of the 4680 next year,” Musk said.

Musk also added that it appears that Tesla is about 12 or not more than 18 months away from volume production of the 4680 cells. At the same time, Tesla is also looking to ramp the 4680 cells with its existing suppliers. The 4680 revolution is not a Tesla-only thing. It will involve CATL and LG and Panasonic as well. Ultimately, Tesla is on track to more than double the output from suppliers.

15:24 PT – An inquiry about vehicle production is asked. Musk notes that people still do not understand the difficulties of production. “Prototypes are child’s play,” he said, noting that mass-production is insanely difficult. Musk notes that Tesla is the first company to achieve volume production of cars in a hundred years and not go bankrupt. “Tesla has had several aneurysms to get this done,” Musk said.

Musk shared some of the challenges that Tesla experienced over the years, from production stops due to trivial items like carpets and USB ports. “Solving those constraints is insane,” Musk reiterated.

15:16 PT – An inquiry about vampire drain was asked. Musk notes that vampire drain is not an issue. “We’ve got a long way to go before we’re dealing with season technology issues,” he said.

15:15 PT – An inquiry about MSM FUD is asked. Elon comments on the “extremely deceptive” media coverage of the Texas crash. According to Lars Moravy, VP of Vehicle Engineering, Tesla is working with Texas authorities about the high-profile, tragic accident. Tesla has conducted a study to understand what happened in the crash together with authorities. As per the findings, it appears that the steering wheel was deformed, and someone was in the driver’s seat during the crash. All seatbelts were unbuckled in the car.

15:11 PT – A question about digital currencies are asked for Zachary Kirkhorn. He reiterates Tesla’s Bitcoin investment and eventual sale, as well as the company’s decision to support Bitcoin for payments. According to Kirkhorn, Tesla had been looking for a place to store its cash. Bitcoin presented itself as a preferable avenue for such an endeavor, considering that traditional systems simply provide far less.

“Bitcoin was a good place to put Tesla cash and be able to get some return on it,” he said. Considering that Tesla added over $200 million from its investment in a few months, this decision definitely seems well worth it. “We’ve been pleased with how much liquidity there is in the Bitcoin market. We do we believe long-term in the value of Bitcoin,” Kirkhorn said.

15:08 PT – Musk continues to discuss the Powerwall’s potential, noting that the home battery’s virtual power plant capabilities are profound. This is especially notable considering that the world is now heading towards an era where EVs are the norm. With this in mind, there has to be a way to produce more electricity to meet the demand that would be produced by an all-electric future.

Considering Tesla’s mission, this shift would be beneficial to the company. “This is a prosperous future for Tesla and for utilities ,” he said. Otherwise, we will see more of what happened in Texas earlier this year. “If this is not done, utilities won’t be able to serve their customers. We’ll see a lot more of what we saw in Texas and California,” Musk said.

15:05 PT – Next question is up. This time it’s about the Solar Roof, its price increase, and its ramp. Musk notes that Solar Roof demand is strong, though he admits that Tesla has made mistakes in evaluating the difficulties in assessing the difficulty of installing the solar tiles. “You can’t have a one size fits all system,” he said.

Musk reiterated Tesla’s decision to bundle the Powerwall and its solar products, adding that batteries produced last year have a higher peak capability. With the bundle in place, musk states that the difficulty of installations would be much easier. Installers would not even need to touch the house’s circuit breaker. This, according to Musk, is important for scalability.

15:00 PT – Elon notes that Tesla is actually getting good at auto-labeling, which is pretty much the holy grail for neural net training. This is something that Dojo would be designed for.

“We think Dojo would be probably an order of magnitude more cost-efficient in hardware and energy usage compared to the next best solution we’re aware of. Possibly it could be used by others,“ Musk remarked, adding that “Probably others would want to use it too. And if they do, we’d make it available.”

14:57 PT – Retail investors from Say begin. First up is a question about Dojo. Elon notes that right now, people think Tesla is a car and energy company, but in the long run, people will likely see Tesla as a robotics company. “I think we are developing some of the strongest hardware and software teams in the world,” he said. And if one were to look at Tesla’s tech evolution, Tesla came to a point where it needed something more powerful than what the market offers.

It then makes sense for Tesla to create a supercomputer that would help train its neural nets. “If you have a system that has very good eyes, which can see in all directions at once, never gets tired, has redundancy, and whose reaction time is superhuman, then such a system would achieve a high level of safety,” Musk said, describing the thinking behind Project Dojo. With over a million cars, after all, that’s a lot of data. And next year, this would grow to two million.

14:53 PT – Tesla has trimmed its Bitcoin investment by 10%, resulting in a profit of $272 million.

14:50 PT – Zachary Kirkhorn explains the Model S and Model X delays, noting that the delays are a meaningful headwind for the company’s finances. He also highlights that Tesla is experiencing some challenges with the ongoing global supply shortage, though the company is working with its partners to address them.

14:48 PT – Elon adds that Model X should ramp in Q3 2021. “We’re going to aim to produce 2,000 Model S and Model X per week,” Musk said. He also adds that he believes that the two flagship cars would see a lot of demand.

Musk also highlighted that the new Model S and Model X are actually cheaper to produce. Giga Berlin and Giga Texas would likely see volume production next year. In closing, he thanks the Tesla team for their efforts.

14:45 PT – Elon notes that solving FSD is a matter of having a massive data set. And in this case, Tesla has an edge with its large fleet of over a million cars on the road. This should help the company handle edge cases. “It’s quite tricky, but we’re highly confident that we’ll get this (FSD) done,” Musk said.

“Q1 had some of the most difficult supply chain challenges that we’ve ever experienced at Tesla,” Musk said, describing the ongoing chip shortage currently plaguing the auto industry.

As for Model S and Model X, Musk notes that there are more challenges than expected. Musk lists some improvements coming to the vehicles, such as their new interior, battery pack, electric motor, and features. Elon adds that Tesla is just making refinements to cars that are already built. A ramp is coming likely in May.

14:40 PT – The Q1 earnings call begins. Martin Viecha takes the floor. Elon Musk, Zachary Kirkhorn, and a number of executives are present in the call. Opening remarks from Elon Musk. He highlights that Q1 was a record quarter for Tesla. He says that Tesla has seen a shift in the perception for EVs, and demand has been even more formidable than ever. “Demand is the best we’ve ever seen,” he said. This is the reason why Q1 became such an outlier compared to past first quarters, which tended to be softer than other quarters.

Elon also mentions the Model 3’s victory in the premium sedan market, beating veterans like the BMW 3-Series. As for the Model Y, the CEO states that the vehicle has a chance of becoming the best-selling car in the world of any kind. Elon estimates that this would happen sometime in 2022. As for FSD, the Beta has been making progress, though Musk admits that it is one of the most difficult technical problems out there. Elon also emphasizes Tesla’s vision-only approach, reiterating his previous statements on Twitter about radar eventually being retired.

14:32 PT – Of course it’s on Elon Time. 😀

14:30 PT – And… it’s time! Butts in seats, everyone.

14:28 PT – And the earnings call stream is live. We’re now treated with some classical music. Definitely a celebratory air here.

14:25 PT – Now that the Tesla Semi has been announced to be on track for a 2021 release, perhaps we’d see more updates on the release of the next-generation Roadster too? The Semi and new Roadster were unveiled at the same time, after all.

14:20 PT – While the Q1 Update Letter is rife with information, there are quite a number of things that were not mentioned as much. A big one is the company’s 4680 battery cell production developments and plans, which were notably absent in the Update Letter. Hopefully, we can get some nice tidbits of information about the 4680 cells in the earnings call. Crossing our fingers.

14:15 PT –  Good day, everyone, and welcome to another live blog of Tesla’s earnings call! We all knew that this quarter would be special when the Q1 vehicle delivery and production numbers came out. Even Wall Street was optimistic about the company’s numbers. Well, the Q1 results are here, and they are actually better than expected. Tesla soundly beat Wall Street’s expectations for revenue and EPS. Though in true Tesla fashion, TSLA stock has now dipped around 1.9% after 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.

Published

on

By

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.

Elon Musk breaks silence on OpenAI trial decision

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.

Elon Musk admits he was ‘clearly wrong’ about Anthropic

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.

Concept art of a Tesla Cybercab in Las Vegas Strip as rendered via Grok

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.

Published

on

By

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.

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.
