Tesla’s (TSLA) Battery Day is charging Jim Cramer’s valuation: “It’s Game, Set, Match”
Tesla (NASDAQ: TSLA) fan and former critic of the company Jim Cramer is looking forward to Battery Day on September 22, and it is fueling his valuation of the automaker who he once considered to be a guaranteed “sell” in the stock market.
An interview with Tesla Daily and TheStreet’s Rob Maurer allowed Cramer to clear the air about his thoughts for the electric car maker. However, looking forward, Cramer is excited for the company’s upcoming Battery Day, because he feels that it could be a key to spiking Tesla’s valuation into the stratosphere.
“What’s key to my valuation, Rob, is what Elon Musk will say on September 22,” Cramer said. Expecting Tesla to roll out a battery cell that could run for ten or twelve hours because of solar energy, Cramer admits he is not familiar with what Musk will unveil during the event. Any way Tesla puts it, Cramer believes it is “Game, Set, Match” for the automotive industry.
Maurer explained the more popular beliefs of Battery Day to Cramer, stating that Tesla will outline its battery strategy for the world to feast on. Additionally, Tesla could explain how it intends to increase annual battery production across all of its products, and not just its cars.
Maurer, like any Tesla enthusiast, knows that a lot of hype surrounds Battery Day. Nobody truly knows what will occur in late September or what the expectations are, but one thing is for sure, Wall Street will have its eyes set in Fremont, where the event is taking place.
“I think one thing that investors need to try to understand is really what those expectations are from the broad Wall Street community. Whether they’re expecting some huge technological breakthrough, or whether they’re going to be satisfied with, ‘Okay, here’s our plan to rapidly, capitally efficiently ramp up to a couple of Terawatt hours of battery production.’ I think there is going to be a lot of technological focus, but I think a lot of it is going to be on that capital efficiency and production ramping angle,” Maurer stated.
Ultimately, Tesla wants to increase the longevity of its battery packs, so its vehicles are capable of lasting fifteen or twenty years without having to undergo cell replacements. With that, the company also wants to improve the energy density that its cells can handle, which will lead to increased range within its vehicles.
Cramer, while a Tesla fan, is still an investor, and he believes that his valuation of the company ultimately comes down to what happens on September 22. If Tesla unveils a significant development in terms of its battery goals, the stock will go up. However, he’s advising some investors to proceed with caution, just in case.
“It [Battery Day] may be one of those events where, if you don’t own it, you may want to wait until after, if he doesn’t deliver along the line that people want him to deliver,” Cramer said. “I mean, one of the things I like about Elon Musk is that he’s not thinking about what you want, like Steve Jobs. He’s thinking about what you will want well ahead of when you know it. So he may be over the heads of people on September 22, and that means some people may be disappointed because they didn’t get what they want, not realizing they’re getting twice what they want if they would just shut up and listen.”
This fact leads Cramer to believe that the stock will go higher after Battery Day. Like many people, Battery Day is among Tesla’s most anticipated events in the company’s history because it is more significant than cars and energy storage; it is the future of our planet.

California snubs Tesla in its newly passed EV incentive that favors Rivian and Lucid
California passed a $135 million EV incentive that rewards Rivian and Lucid while sidelining Tesla
California just drew a line in the EV incentive sand to put Tesla on the wrong side of it. The state recently passed a $135 million program offering first-time electric vehicle buyers a direct incentive with no application required, but the rules were written in a way that leaves Tesla at a structural disadvantage compared to Rivian and Lucid.
The program caps eligible vehicles at $50,000 for new EVs and $25,000 for used ones. That pricing threshold rules out a significant portion of Tesla’s lineup, though some lower-priced Model 3 and Model Y configurations would still qualify. California-based automakers are exempt from the price cap entirely, regardless of what their vehicles cost. Rivian, headquartered in Irvine, and Lucid, based in the San Francisco Bay Area, both benefit from that exemption. Rivian’s R2 starts at roughly $45,000 but has versions above the cap. Lucid’s Air and Gravity start at $70,990 and $79,990 respectively, well above any threshold a non-California company would face.
California hits Tesla Cybercab and Robotaxi driverless cars with new law
Tesla built its reputation and a significant portion of its early market share in California, where EV adoption has consistently led the nation. The company operates its original factory in Fremont, California, and the state was home to Tesla’s headquarters for most of its existence. That changed in 2021 when Tesla moved its corporate headquarters to Austin, Texas. Since then, the relationship between the company and California Governor Gavin Newsom has been openly adversarial, with Musk and Newsom trading public criticism on multiple occasions.
California’s EV incentive landscape has shifted repeatedly in recent years, and Tesla has previously lost eligibility for state-level programs as its vehicles exceeded income-adjusted price thresholds. The federal $7,500 EV tax credit, which Tesla models have qualified for and lost depending on policy cycles, is no longer available after it expired without renewal, making state-level programs more meaningful to buyers than they have been in years.
The practical impact for buyers is more nuanced than the headline suggests. California residents purchasing a Tesla under $50,000 for the first time can still access the incentive. But the exemption written for California-based manufacturers is a structural advantage that rewards where a company plants its headquarters flag rather than where it builds its products, and Tesla moved that flag to Texas.

SpaceX’s newest logo confirms everything about what it’s become
SpaceX officially absorbed xAI under the SpaceXAI brand, completing the largest private merger in history.
SpaceX made its corporate transformation official in May 2026 when Elon Musk posted on X that xAI would cease to exist as a standalone company. “xAI will be dissolved as a separate company, so it will just be SpaceXAI, the AI products from SpaceX,” he wrote.
A new SpaceXAI logo was announced today, visually embedding the xAI letters inside the SpaceX identity, which can be seen as a deliberate design choice that signals the merger is not a partnership but a full absorption and XAi a core function of the same company. The same way Starlink is not a separate brand but a SpaceX product. The announcement closed the loop on a process that began February 2, 2026, when SpaceX acquired xAI in the largest private merger in history, valued at $1.25 trillion. SpaceX at $1 trillion and xAI at $250 billion.

The reason SpaceX bought xAI was stated plainly by Musk at the time of the deal: to build orbital data centers. SpaceX had simultaneously filed with the FCC to launch up to one million satellites designed to function as AI compute nodes in low Earth orbit, escaping what Musk described as the energy constraints limiting AI development on Earth.
xAI provided the AI software stack, with Grok, the X platform, and the Colossus supercomputer infrastructure in Memphis with over 220,000 NVIDIA GPUs, while SpaceX provided the rockets, Starlink, and the capital base to fund it. The two companies needed each other. xAI was burning $2.5 billion in losses on $250 million in revenue. SpaceX was generating an estimated $8 billion in profit on $15 billion in revenue and needed an AI narrative to command the valuation it was targeting for its IPO.
What SpaceX has done, regardless of how the orbital AI vision ultimately plays out, is walk into a public market as something no company has been before: a rocket manufacturer, satellite internet provider, AI software company, social media platform, and supercomputer operator under one ticker. Whether that combination is worth $2 trillion depends entirely on which of those businesses you believe in most.

Tesla challenges startups to score a gig inside its most advanced European factory
Tesla is challenging startups to bring their best battery tech directly to Gigafactory Berlin.
Tesla has issued an open challenge to startups across Europe, inviting them to bring their best battery technology directly to the floor of Gigafactory Berlin. The program, called the JUNI x Tesla Battery Cell Giga Challenge, opened applications this month with a deadline of July 24, 2026, and is targeting startups with solutions that can make battery cell manufacturing faster, cheaper, safer, and more scalable at an industrial level.
The timing of the challenge is directly tied to Tesla’s most aggressive European battery investment yet. On May 12, 2026, Giga Berlin plant manager André Thierig announced a $250 million investment to scale the factory’s annual 4680 cell production capacity from 8 GWh to 18 GWh, more than doubling the previous target set just months earlier in December 2025. Thierig confirmed the expansion on X, saying the investment “will enable 18 GWh of annual 4680 cell production and create more than 1,500 new jobs.” Combined with a previously announced battery investment at the Grunheide site now approaches $1.2 billion.
Today, we announced a $ 250m investment for our Giga Berlin Cell factory. This will enable 18GWh of annual 4680 cell production and create more than 1500 new jobs. Good news during challenging times for the German industry. pic.twitter.com/ou4SWMfWh9

The challenge is looking specifically for startups with proven solutions across five categories: materials, equipment, operations, automation, and artificial intelligence. Applications are screened directly by Tesla’s cell manufacturing team in Grunheide, and the strongest submissions move through technical discussions, a pitch day in front of Tesla stakeholders, and potentially a paid pilot project with the cell team. Tesla is not looking for ideas at concept stage. The program requires applicants to demonstrate working prototypes, test data, or prior pilots before being considered.
The historical context matters here. Elon Musk first announced plans for what he called the world’s largest battery cell production facility alongside the Giga Berlin car factory back in 2020, targeting up to 250 GWh of annual capacity. Those plans were shelved in 2022 when Tesla shifted its battery investment focus to the United States to take advantage of Inflation Reduction Act incentives. The revival of cell production at Giga Berlin, now backed by over $1 billion in committed capital, represents a return to an ambition that was set aside for three years. As Teslarati has reported, the 4680 format is central to Tesla’s long-term cost reduction strategy across vehicles, energy storage, including the Tesla Semi and Cybercab.
By opening the challenge to outside startups, Tesla is acknowledging that reaching 18 GWh at Grunheide will require technology it does not currently have in-house, and it is willing to pay for the right solutions. For a startup in the battery supply chain, a paid pilot with Tesla’s European cell team is as close to a direct commercial path as the industry offers.
