Tesla’s battery supply constraint is ending, price parity with gas cars is at hand
Tesla’s Semi is coming, and it will be here sooner than expected. But the production of the vehicle could be pointing to one thing: Tesla is no longer battery constrained.
Past the face value portion of the story, something much bigger is happening. While the Semi entering a “volume production” phase is big news, the development of the commercial vehicle comes at a time where battery production for Tesla seems to be the main focus of the electric automaker.
In Q3 2019, CEO Elon Musk indicated that a shortage of battery cells primarily drove the Semi’s delay. If Tesla wanted to start producing the Semi, the company would have to make cells available for it. That would mean one thing: cutting back on cells utilized for Tesla’s mass-market vehicles, which at the time was the Model 3.
Building the Semi before a sufficient battery production and supply chain was established would have been detrimental to the company’s long-term plans. Of course, the Model 3 has been Tesla’s most popular vehicle since it started deliveries in 2017. Its affordability has helped Tesla reach a new market, which was all apart of Elon’s original Master Plan.
With the Model Y now being produced in Fremont, Tesla now has two mass-market vehicles that are affordable by a vast segment of the population. Ultimately, this means that Tesla needed to levy a majority of its available lithium-ion cells for the Model 3 and Model Y. Unfortunately, the Semi just was not a priority over those two cars. Why would it be? The Model 3 (and Model Y now) are Tesla’s two top sellers. Therefore, the battery needs pointed toward the 3 and the Y, with Semi production being dependent on the availability of battery cells.
If we think about Musk’s statement from Q3, he indicated that the Semi production would be based on when Tesla could manufacture the appropriate amount of lithium-ion batteries to power the Class 8 vehicle. Although demand for the 3 and the Y continues to increase, so is Tesla’s production rate, and it could be indicative that the Silicon Valley-based electric car maker is pumping out enough batteries to produce all of its vehicles without any worries of possible cell shortages.
Ultimately, this idea could lead to another significant development in the EV world as a whole, and that is price parity.
For a long time, analysts have pinpointed the electric vehicle movement’s price parity at $100/kWh for battery cell production. This means that when cells are produced at a high enough rate, batteries will be lower in cost. Then, electric cars will be the same price as gas-powered machines, making the argument of “EVs are too expensive” obsolete.
The Tesla Model 3 Performance utilizes a 75 kWh battery pack. If battery production is at $120/kWh, this would mean that the Model 3 Performance’s battery pack costs $9,000 to produce. The car’s $54,990 price tag, hypothetically at $120 per kWh, is made up of a battery pack that costs about $9,000.
If Tesla could produce batteries at a high enough rate where the cost per kWh could come down to $100, the battery pack would only cost $7,500 to build, meaning an additional $1,500 comes off the price of the vehicle altogether. Tesla’s goal is to produce enough battery cells to justify this pricing point for its cars. Also, $100/kWh is just the price parity point, and not where the cost will ultimately end up. If demand continues to increase and battery cell production keeps growing, the cost could get even lower.
If Tesla has enough batteries to justify producing mass quantities of the Model 3 and Model Y, along with the sizable battery packs of the Semi, parity could be coming sooner than expected. Most analysts indicated 2023 as the year when battery production would be on a level where EV prices could compete with their petrol-powered counterparts.
However, if the Semi is ready for a production run now, Tesla may have enough cells to introduce a more affordable pricing model for its vehicles. This could, in turn, lead to even higher production numbers, increased demand, and a sharp increase in the company’s delivery numbers.
The announcement of the Tesla Semi meant much more than the company producing its commercial vehicle. It means batteries are no longer in restricted amounts, the technology is improving, and the prices of the company’s vehicles could be coming down soon. With this, it appears that Elon Musk’s endgame with his Master Plan may be getting closer to reality.
Tesla (NASDAQ: TSLA) is set to hold its Earnings Call for the first quarter of 2026 on Wednesday, and there are a lot of interesting things that are swirling around in terms of speculation from investors.
With the company’s executives, including CEO Elon Musk, answering a handful of questions that investors submit through the Say platform, fans want to know a lot of things about a lot of things.
These five questions come from Retail Investors, who are normal, everyday shareholders:
- When will we have the Optimus v3 reveal? When will Optimus production start, since we ended the Model S and Model X production earlier than mid-year? What’s the expected Optimus production rate exiting this year? What are the initial targeted skills?
- What milestones are you targeting for unsupervised FSD and Robotaxi expansion beyond Austin this year, and how will that drive recurring revenue?
- How will Hardware 3 cars reach Unsupervised Full Self-Driving?
- When do you expect Unsupervised Full Self-Driving to reach customer cars?
- When will Robotaxi expand past its current limited rollout?
Additionally, these are currently the three questions that are slated to be answered by Institutional Firms, which also answer a handful of questions during the call:
- Now that FSD has been approved in the Netherlands and is expected to launch across Europe this summer, can you discuss your Robotaxi strategy for the region?
- What enabled you to finish the AI5 tapeout early and were there any changes to the original vision? Last week, Elon said AI5 will go into Optimus and the Supercomputer, but one month ago said it would go into the Robotaxi. Has AI5 been dropped from the vehicle roadmap?
- Given the recent NHTSA incident filings, can you update us on the Robotaxi safety data? If safety validation remains the primary bottleneck, why not deploy thousands of vehicles to accelerate the removal of the safety driver?
The questions range through every current Tesla project, including FSD expansion and Optimus. However, many of the answers we will get will likely be repetitive answers we’ve heard in the past.
This is especially pertinent when the questions about when Unsupervised FSD will reach customer cars: we know Musk will say that it will happen this year. Is Tesla capable of that? Maybe. But a more transparent answer that is more revealing of a true timeline would be appreciated.
Hardware 3 owners are anxiously awaiting the arrival of FSD v14 Lite, which was promised to them last year for a release sometime this year.
The Earnings Call is set to take place on Wednesday at market close.

Elon Musk reveals shocking Tesla Optimus patent detail
What looked promising on paper and in simulations failed to deliver the reliability required for a robot expected to handle delicate tasks like folding laundry, assembling electronics, or assisting in factories and homes.
Elon Musk revealed a shocking detail on the Tesla Optimus patent that was revealed last week. Despite it being made public for the first time, Musk said the company has already moved on from the design, an incredible truth about the development of new technology: things move fast.
Musk dropped a bombshell about the Tesla Optimus humanoid robot hand patent that was released last week. Musk, candidly replying to a post late at night on X, revealed that what is a new technology to many fans and insiders is actually old news to those developing the tech directly.
“We already changed the design,” Musk said. “This one didn’t actually work.”
We already changed the design. This one didn’t actually work.

Patents, after all, are often viewed as blueprints for future products. Yet Musk revealed that the rolling contact mechanism—intended to provide smooth, low-friction articulation in the fingers—had already been scrapped after real-world testing exposed its shortcomings.
What looked promising on paper and in simulations failed to deliver the reliability required for a robot expected to handle delicate tasks like folding laundry, assembling electronics, or assisting in factories and homes.
The hand has been one of the biggest challenges for Tesla engineers since Optimus development started years ago. Musk has said that there is not enough recognition for how incredible and useful the human hand is, and designing one for a humanoid robot has been the biggest challenge of all.
Tesla is stumped on how to engineer this Optimus part, but they’re close
This moment underscores the persistent engineering hurdles in achieving reliable humanoid hand dexterity. Human fingers are marvels of evolution: 27 bones, intricate tendons, ligaments, and a network of sensors working in perfect harmony. Replicating that in metal and silicon is extraordinarily difficult.
Rolling contacts promised reduced wear and precise motion, but testing likely revealed issues with durability under repeated stress, grip stability on varied surfaces, or the micro-precision needed for fine motor skills.
These aren’t minor tweaks, but instead they represent fundamental challenges that have plagued robotics teams for decades. Even advanced competitors struggle here—hands remain the Achilles’ heel of most humanoids because the margin for error is razor-thin.
A fraction of a millimeter off, and a robot drops a glass or fails to button a shirt.
What makes Musk’s reply remarkable is how it signals Tesla’s direct communication style on prototype limitations. While many companies guard failures behind glossy marketing and vague timelines, Tesla openly shares setbacks.
Musk was forthcoming about the failure of this recent design. This transparency builds trust with investors, engineers, and fans. It shows Tesla treats Optimus development like true science: rapid iteration, rigorous testing, and zero tolerance for hype that doesn’t match reality.
The disclosure from Musk also highlights Tesla’s blistering pace of development. By the time the patents are published, which is often over a year after the initial filing, the technology has already evolved.
Optimus is far from a static product, and it’s a living project advancing weekly.
In the high-stakes race for general-purpose robots, Tesla’s approach stands out. Admitting a finger-joint design “didn’t actually work” isn’t a weakness—it’s confidence.
True innovation demands confronting failure head-on, and Musk just reminded the world that Optimus is being engineered that way. The next version of those hands is already in testing, and it will be better because Tesla isn’t afraid to say what didn’t work.

Tesla is sending its humanoid Optimus robot to the Boston Marathon
Tesla’s Optimus robot is heading to the Boston Marathon finish line
Tesla’s Optimus humanoid robot will be stationed at the Tesla showroom at 888 Boylston Street in Boston, right along the final stretch of the Boston Marathon today, ready to cheer on runners and pose for photos with spectators.
According to a Tesla email shared by content creator Sawyer Merritt on X, Optimus will be at the Boston Boylston Street showroom on April 20, coinciding with Marathon Monday weekend. The Boston Marathon finishes on Boylston Street, and the surrounding area draws hundreds of thousands of spectators along with international broadcast coverage. Placing Optimus there puts it in front of a massive public audience at zero advertising cost.
Just got this email. @Tesla’s Optimus robot is coming to Boston.

The Tesla showroom is at 888 Boylston Street, between Gloucester Street and Fairfield Street. The final mile of the marathon runs directly along Boylston Street, with runners passing the big stores before reaching the finish line at Copley Square.
Optimus was first announced at Tesla’s AI Day event on August 19, 2021, when Elon Musk presented a vision for a general-purpose robot designed to take on dangerous, repetitive, and unwanted tasks. In March 2026, Optimus appeared at the Appliance and Electronics World Expo in Shanghai, where on-site staff stated that mass production of the robot could begin by the end of 2026. Before that, it showed up at the Tesla Hollywood Diner opening in July 2025 and at a Miami showroom event in December 2025.
Tesla’s well-calculated display of Optimus gives the public a low-pressure first encounter with a robot that Tesla is preparing to soon deploy at scale. The company has previously indicated plans to manufacture Optimus robots at its Fremont facility at up to 1 million units annually, with an Optimus production line at Gigafactory Texas targeting 10 million units per year.

Musk has said that Optimus “has the potential to be more significant than the vehicle business over time,” and separately that roughly 80 percent of Tesla’s future value will come from the robot program. Whether that holds depends on production execution. For now, Boston gets a preview of what that future looks like, standing at the finish line on Boylston Street while 32,000 runners pass by.
