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.

Elon Musk
The real reason Elon Musk wants every car connected to space
Elon Musk says all cars will eventually need Starlink to handle massive AI bandwidth demand.
Elon Musk is making the case that satellite internet, not fiber or cellular towers, will end up wired into every car on the road. In a string of posts on X, the SpaceX CEO wrote that all cars will have Starlink in the future and called satellite connectivity the only way to get super high bandwidth to billions of vehicles.
The posts started with Musk endorsing a Cloudflare forecast that traffic generated by autonomous AI agents will soon dwarf traffic generated by humans browsing the internet, a shift he described as not a close call at all. From there he narrowed the argument to infrastructure, writing that the only system that can support the insanely fast bandwidth growth needed by AI is Starlink, before extending the logic to cars specifically.
AI agentic Internet traffic will obviously VASTLY exceed human usage. Not a close call at all.

The timing lines up with Tesla’s own hardware decisions. On July 20, Tesla confirmed the Cybercab would ship with a Starlink V5 terminal built into its roof, the first time the company had put satellite hardware in a production vehicle. A day later, Tesla’s head of AI, Ashok Elluswamy, explained the connection wasn’t there for safety and that Cybercab’s driving stack runs entirely on onboard cameras and compute, while the satellite link exists for navigation, customer service, and fleet management instead. Musk followed with his own post about the feature, saying riders would be able to watch 4K streaming video during rides.
By July 22, Musk had already said Starlink would extend beyond Cybercab to Tesla’s full lineup. Sunday’s posts push that same logic outward again, this time framed as a requirement across the industry rather than a feature specific to Tesla, and tied directly to the bandwidth AI systems are expected to consume.

The AI argument has been building on SpaceX’s side for months. The company has an FCC filing pending for a third generation Starlink constellation, and it has separately proposed Starmind, a constellation of up to a million satellites designed to run AI computation directly in orbit rather than just relay data. Musk has said he expects space to become the cheapest place to deploy AI compute within two to three years. Starlink and Starmind serve different jobs inside that vision, one moving data and the other processing it, but Sunday’s posts treat vehicles as one more category of hardware that will eventually need both.
None of this changes anything for Tesla owners today. Cars already on the road keep running on LTE and Wi-Fi, and Tesla hasn’t outlined a retrofit path for existing vehicles. The July 22 commitment applies to future production, not the fleet already delivered. What Musk added on Sunday is the reasoning: satellite connectivity isn’t a Cybercab novelty, it’s a bet that ground based networks won’t keep up with how much data cars, robots, and AI systems are about to generate.
SpaceX stock did the opposite of what most of Wall Street expected this week, when the day designed to be its most dangerous turned into a rally, and the rally kept going.
Thursday marked the first major lockup expiration since SpaceX’s June IPO, making roughly 911.5 million insider held shares eligible to trade for the first time, more than doubling the company’s public float. Analysts and short sellers had spent weeks bracing for a flood of selling, especially after the stock fell 13 percent following its first earnings report as a public company on Tuesday. Instead, shares rose 6.1 percent Thursday to close at $114.92, and by Friday they were trading near $129, up more than another 12 percent on the day.

The setup made the outcome notable. Short interest had climbed to roughly 34 percent of the float heading into earnings, among the highest of any large cap stock, with about 95 percent of available shares to borrow already on loan. CEO Elon Musk warned short sellers twice in the weeks before the lockup, writing on X that “the survival probability of firms who maintain a significant short position in SpaceX over time is very low,” then following up on the morning of earnings with “I try to warn them, but they just double down.”
When the newly unlocked shares hit the market and the selloff never showed up, some of that short position appears to have started unwinding. TipRanks reported that options activity shifted toward bullish strategies like put selling and risk reversals following the rally, with roughly $600 million in options premium trading Thursday alone. Retail buyers also stepped in during the earnings dip, according to Vanda Research.
The fundamentals behind the stock have not changed much in a week. SpaceX’s revenue nearly doubled year over year to $7.8 billion, with Starlink subscribers doubling to 12 million and the company’s AI segment growing 247 percent. What spooked investors on Tuesday was the spending side. Capital expenditures jumped to more than $18 billion for the quarter, up from $2.8 billion a year earlier, with AI investment alone rising from $749 million to $15.8 billion. Wall Street remains split on whether that spending is building infrastructure SpaceX needs or outrunning what the business can currently support, a debate Teslarati has tracked since shares first came under pressure.
None of that resolves the bigger question hanging over the stock. Thursday’s release was only the first of nine staggered lockup tranches, with roughly $800 billion worth of additional shares scheduled to become eligible through October, and Musk’s own stake stays locked until next June. If this week is any indication, the market is treating that supply as something it can absorb rather than something to fear, at least for now.

Cybertruck
Tesla Cybertruck production snaps back after ugly supplier fight
Cybertrucks are piling up again at Giga Texas after Tesla’s court win against a parts supplier.
Cybertruck production at Giga Texas is showing its first visible recovery since Tesla sued a supplier last month over withheld manufacturing tooling.
Aerial observer Joe Tegtmeyer flew over the Austin factory Wednesday morning and counted roughly 100 or more Cybertrucks filling the outbound lot, a sharp jump from the thin numbers seen in recent weeks. The flyover came a day after a judge granted Tesla a temporary restraining order against Angstrom Automotive Group, the parts supplier at the center of the dispute.
Tesla filed an emergency lawsuit in late July after Angstrom told the automaker it planned to close the Troy, Texas facility where Tesla’s die-cast tools, trim dies and other Cybertruck stamping equipment were housed. According to Tesla’s complaint, a shipment of 700 finished parts never left the building, and when Tesla sent representatives to retrieve its equipment, accompanied by law enforcement, they were turned away. Angstrom allegedly then asked for an extra $250,000 a week to keep operating, which Tesla’s filing described as holding its own property for ransom.
TESLA: U.S. District Judge Christopher R. Wolfe of the U.S. District Court for the Western District of Texas, Waco Division granted Tesla a Temporary Restraining Order and Writ of Replevin in its dispute with Angstrom Automotive (Case No. 6:26-cv-00477).

The restraining order gives Tesla immediate right of entry to Angstrom’s facility to recover the tooling. It is temporary, with a fuller hearing still to come, but the speed of Wednesday’s rebound suggests the Angstrom shortage was indeed the main bottleneck limiting Cybertruck output. Outbound lot counts are an imperfect measure of actual production, since finished trucks can sit for days before shipping, but a lot that full after a lean stretch is a meaningful signal.
Cybertruck output at Giga Texas has fluctuated all year as Tesla worked through supply issues and introduced new trims, including a cheaper Dual Motor AWD version that drew strong early demand.
