Tesla Stock Soars 16+% in 1 Day
Tesla’s Model S sedan is red hot.
By Silicon Valley standards, 10-year-old Tesla Motors is middle-aged. But in the world of automotive startups, it’s just crossed a threshold few fledgling companies ever get near: profitability. Late last night California time — in time to make it clear this was no April Fools joke — the company announced it has delivered 4750 cars in the first quarter and expected to report an accounting profit when it announces its official results next month. While the company’s vehicles lack engines, in the past 6 months, it’s begun to hit on all cylinders:
- Shipments of the Model S sedan begin late last year with 2400 delivered in the fourth quarter. The company nearly doubled that in the next 3 months.
- Tesla launched its high-speed “Supercharger” charging stations, which allow recharging half the battery pack in about 30 minutes. Last week, it announced plans to expand the network in the Pacific northwest, Texas, Illinois, and Florida, while improving coverage in the initial regions in the northeast and California.
- The company announced a plan to pay back its Department of Energy loan 5 years ahead of schedule, by the end of 2017. This $465 million loan, part of the Advanced Technology Vehicle Manufacturing Program, was essential to the launch of the Model S and came at a time when Tesla’s future was very much in doubt.
Today, though, that future looks bright enough that the naysayers holding more than 30 million shares short may be wishing they were betting against something else. CEO Elon Musk mentioned on Twitter last week that he had a big announcement to make regarding Tesla (due tomorrow) and clarified last night that this isn’t it: “Also, some may differ, but imo the Tues news is arguably more important,” he wrote. Depending on the nature of that, I may be back with another post.
There was some more interesting news in yesterday’s press release on profitability. The company canceled an option to buy the Model S with the smallest battery, a version that retailed for just around $52,000 after the federal tax credit. Why? Lack of demand. It seems only 4% of buyers were opting for that smallest configuration. They’ll still get it, but instead of producing a battery that small, Tesla will sell them a car with the mid-sized battery and disable part of the capacity in software. If owners — present or future — wish to upgrade to the larger capacity, Tesla will allow them to purchase some software magic to make it happen. The mid-sized battery offers a range of just over 200 miles per the EPA and the smallest battery has about 2/3 the capacity. Given there was a $10,000 gap between the two, it’s noteworthy that people were rejecting the smallest battery so clearly.
This points out the radically different approach Tesla is taking versus Nissan with the Leaf and really everyone else building electric vehicles right now. The two sizes of Tesla people are choosing are 200+ mile vehicle while the other brands are sold as 70-80 mile commuter vehicles. Apparently, a “tweener” that gets around 140 miles wasn’t something Tesla customers wanted and might not be appealing to much of anyone as it doesn’t really address the “go almost anywhere” problem Tesla is solving and doesn’t really do much for commuters. (More than 80% of commutes in the U.S. can be made roundtrip in a Leaf.)
In addition to eliminating the small battery, Tesla also decided to build access to the Supercharger network in every car. It was already standard with the largest battery and is still an option with the smaller one, but now you can decide to add the option after purchase because — again — it’s a software change. The Superchargers are free “fill-ups” along highway corridors, but those with the smaller battery will pay $2000 for the privilege. This software-upgradeable car might not be as much of a milestone as a 200+ mile EV is, but it has already become a hallmark of the way Tesla works and really shows how Silicon Valley DNA can be an important part of this 21st century automaker.
When the company announced its earnings last quarter, the news actually disappointed investors. On some level, that was odd because the quarter inherently represented a transition where production was ramping up and it would be hard to really get a sense of what the business looked like on a steady-state basis. This quarter, however, is going to provide a very real snapshot into Tesla as a business. Through the rest of 2013 and well into next year, the company is likely to look as it does this quarter, with small improvements in unit shipments and gross margin over each quarter until the company begins delivering its Model X crossover late in 2014. None of that is likely exciting to watch, but it is likely to be material financially.
If deliveries do creep into the range of 6000-7000 per quarter — which is expected — and the company hits its gross margin goal of 25% by year end, this quarter’s profit is going to be pretty small compared to the ones set to come. It’s this kind of steady profitable growth upon which you build a company that will be around for a long time to come. And with the focus on larger batteries and more Superchargers, Tesla seems to be saying its cars are going to run long and far as well.
Tesla has taken home the “Overall Loyalty to Make” award from S&P Global Mobility for the fourth consecutive year, reinforcing Tesla owners’ willingness to come back. The 2025 awards are based on S&P Global Mobility’s analysis of 13.6 million new retail vehicle registrations in the U.S. from October 2024 through September 2025. The complete list of 2025 winners includes General Motors for Overall Loyalty to Manufacturer, Tesla for Overall Loyalty to Make, Chevrolet Equinox for Overall Loyalty to Model, Mini for Most Improved Make Loyalty, Subaru for Overall Loyalty to Dealer, and Tesla again for both Ethnic Market Loyalty to Make and Highest Conquest Percentage.
Tesla’s streak in this category started in 2022, and the brand has now won the Highest Conquest Percentage award for six straight years, meaning it keeps pulling buyers away from other brands at a rate no competitor has matched. Tesla’s retention among Asian households reached 63.6% and among Hispanic households 61.9%, rates that significantly outpace national averages for those groups. That breadth of appeal across demographics adds a layer of significance to a win that some might dismiss as routine.
The timing matters too. After several consecutive quarters of decline, Tesla’s share of U.S. EV sales jumped to 59% in Q4 2025. That rebound, arriving just as competitors were flooding the market with new models and incentives, suggests Tesla’s loyalty numbers are not simply the result of limited alternatives. Buyers are still choosing it when they have plenty of other options.
What keeps Tesla owners coming back has a lot to do with the and convenience of charging. The Supercharger network is the most straightforward example. With over 65,000 Superchargers globally, it remains the largest and most reliable fast-charging network in the world, and owners who have built their routines around it face a real practical cost when considering a switch. Competitors have made progress, but the consistency, speed, and availability of Tesla’s network is still the benchmark the rest of the industry is chasing. Then there is the software side. Tesla has built a model where the car you own today is functionally different from the car you bought two years ago, through over-the-air updates that add continuous game-changing improvements such as Full Self-Driving that has moved from a driver-assist feature to an increasingly capable autonomous system. For many Tesla owners, leaving the brand means starting over with a car that will not get meaningfully better over time, and that is a trade-off fewer and fewer are willing to make.
Tesla Robotaxi services in Austin have been operating since last Summer, but Tesla has admittedly been delayed in its expansion of the geofence, fleet size, and other details in a bid to prioritize safety as new technology rolls out.
But those barriers are being broken with new guardrails being removed from the program.
Tesla has achieved a significant advancement in its autonomous ride-hailing program. As of May 4, the Robotaxi fleet in Austin, Texas, has begun operating unsupervised during evening hours for the first time. This expansion moves beyond previous limitations that restricted unsupervised service to daylight hours, typically ending in mid-afternoon.

The change brings Austin in line with operations in Dallas and Houston. Those cities have supported evening unsupervised runs since their initial launches in April, and both recently received additions of new unsupervised vehicles to their fleets. This coordinated progress across Texas strengthens Tesla’s regional presence and provides a broader testing ground for the technology.
This milestone carries substantial weight in the development of autonomous vehicles. Extending operations into low-light conditions meaningfully expands the Robotaxi’s operational design domain (ODD)—the specific environments and scenarios in which the system is approved to operate safely without human intervention.
Nighttime driving presents unique technical demands: diminished visibility, headlight glare from oncoming traffic, reduced contrast for identifying pedestrians and lane markings, and greater variability in camera sensor exposure.
Tesla’s pure vision approach, powered by neural networks trained on vast real-world datasets rather than lidar or pre-mapped routes, must handle these variables reliably. Demonstrating consistent unsupervised performance after sunset validates the robustness of the end-to-end AI stack and its ability to generalize across diverse lighting conditions.
Beyond technical validation, the expansion holds important operational and economic implications. Evening hours often coincide with peak urban demand for rides, including commutes, dining, and entertainment outings.
Enabling service during these periods increases daily vehicle utilization, allowing each Robotaxi to generate more revenue while gathering additional high-value training data. Higher utilization accelerates the virtuous cycle of data collection, model improvement, and further ODD growth.
Looking ahead, this step paves the way for more ambitious rollouts. Success in low-light environments positions Tesla to pursue near-24-hour operations, potentially integrating highways and expanding into varied weather patterns. Regulators worldwide frequently demand evidence of safe performance across day-night cycles before granting wider approvals.
Proven capability in Texas could expedite deployments in planned cities such as Phoenix, Miami, Orlando, Tampa, and Las Vegas during the first half of 2026.

Moreover, scaling evening service supports Tesla’s long-term vision of a high-efficiency robotaxi network. Greater fleet productivity lowers the cost per mile, making autonomous mobility more accessible and competitive against traditional ride-hailing.
As the company iterates on software updates informed by nighttime data, reliability is expected to compound rapidly, unlocking denser urban coverage and longer-distance trips.
In summary, the introduction of an unsupervised evening Robotaxi service in Austin represents more than an incremental schedule adjustment. It signals a critical maturation of the underlying technology and sets the foundation for broader geographic and temporal expansion.
With Texas operations gaining momentum, Tesla is steadily advancing toward transforming urban transportation at scale.

Tesla Cybercab just rolled through Miami inside a glass box
Tesla paraded a Cybercab in a glass display at Miami’s F1 Grand Prix event this week.
Tesla set up an “Autonomy Pop-Up” at Lummus Park in Miami Beach from April 29 through May 3, 2026, embedded within the official F1 Miami Grand Prix Fan Fest. The centerpiece was a Cybertruck towing the Cybercab inside a glass display case marked “Future is Autonomous,” rolling through the beachfront crowd.
Miami is on Tesla’s confirmed list of cities for robotaxi expansion in the first half of 2026, making the promotion a strategic promotion that lays groundwork in a target market.
This was not Tesla’s first time using Miami as a showcase city. In December 2025, Tesla hosted “The Future of Autonomy Visualized” at its Miami Design District showroom, coinciding with Art Basel Miami Beach. That event featured the Cybercab prototype and Optimus robots interacting with attendees. The F1 pop-up this week marks Tesla’s return to Miami and follows a pattern Tesla has been running since early 2026. Just two weeks before Miami, Tesla stationed Optimus at the Tesla Boston Boylston Street showroom on April 19 and 20, directly on the final stretch of the Boston Marathon, letting tens of thousands of runners and spectators meet the robot for free, generating massive earned media at zero advertising cost.

Tesla has confirmed plans to expand its robotaxi service to seven cities in the first half of 2026, including Dallas, Houston, Phoenix, Miami, Orlando, Tampa, and Las Vegas, building on the unsupervised service already running in Austin. Musk has said he expects robotaxis to cover between a quarter and half of the United States by end of year. On the production side, Musk told shareholders that the Cybercab manufacturing process could eventually produce up to 5 million vehicles per year, targeting a cycle time of one unit every ten seconds. Scaling robotaxis to 10 million operational units over the next ten years is a key condition of his compensation package, alongside selling 20 million passenger vehicles.
As for the Cybercab’s price, Musk has said buyers will be able to purchase one for under $30,000, with an average operating cost around $0.20 per mile. Whether those numbers hold through full production remains to be seen.
