Former Tesla short seller warns his TSLAQ peers: ‘I wouldn’t do that’
Tesla stock (NASDAQ:TSLA) may have seemingly leveled out in recent days, but a longtime critic of CEO Elon Musk still thinks that it’s too risky to bet against the electric car maker. In recent comments, noted Tesla bear Carson Block admitted that he is no longer shorting TSLA, simply because it is far too dangerous to go against Musk and his EV company.
Block, the founder of Muddy Waters Capital LLC, is a noted critic of Elon Musk. However, in an interview with Bloomberg’s Tracy Alloway and Joe Weisenthal on the Odd Lots podcast on Wednesday, the short seller stated that he no longer has any bearish wagers against Tesla.
“I’m not short the stock, thank God. We used to joke that Tesla, when it files for bankruptcy, will probably have a $30 billion market cap. Short it at your own risk. I wouldn’t do that,” Block said, though he noted that he still believes that Tesla’s business is unsustainable.
Tesla has experienced a rise of over 300% since mid March. Amidst this massive bull run, and as the company exceeded expectations by delivering over 90,000 vehicles in the second quarter, TSLA stock has gained more supporters, especially among retail investors. As of Wednesday, Tesla stock was trading at 182 times its 12 month earnings, versus 10 times for rival American automaker General Motors.
During his segment, Block stated that at one point, he had a TSLA position that involved buying the electric car maker’s convertible bonds and using the coupon payments to fund long dated puts on the stock. Eventually, the short seller admitted that he sold the debt and let the puts expire. Block then issued a warning to fellow Tesla bears, stating that it’s very risky to bet against Elon Musk.
“It’s one thing to bet on Elon Musk, but it’s another thing to bet against him. The guy specializes in pulling rabbits out of the hat,” he said.
While Block was cautious enough to warn short sellers who would like to bet against Tesla, references to Elon Musk “pulling rabbits out of the hat” suggest that the Muddy Waters Capital founder still maintains a rather limited view of the company’s operations and expansion. It is easy to note that Tesla vehicle registrations fell in California during Q2, for example, but one should not neglect the effects of the pandemic, or the company’s numbers compared to other automakers, for that matter.
Tesla is also expanding its vehicle production and deliveries outside the United States, and this was no more evident than in Q2’s results. During the quarter, the company’s deliveries in the US were adversely affected by the pandemic, but sales of the Model 3 picked up in China, propelled by a ramp in Gigafactory Shanghai. And if Gigafactory Berlin goes live with Model Y production next year as planned, Tesla’s sales will be bolstered even more. Very few Tesla critics also acknowledge the potential of Tesla Energy, which is finally starting to ramp its operations.
Disclosure: I have no ownership in shares of TSLA and have no plans to initiate any positions within 72 hours.

Tesla made a change to the Cybertruck and nobody noticed
Tesla made a change to the Cybertruck, and nobody noticed. But to be fair, nobody could have, but it was revealed by the program’s lead engineer that it was aimed toward simplifying manufacturing through a minor change in casting.
After the Cybertruck was given a Top Safety Pick+ award by the Insurance Institute for Highway Safety (IIHS), for its reputation as the safest pickup on the market, some wondered what had changed about the vehicle.
Tesla makes changes to its vehicles routinely through Over-the-Air software updates, but aesthetic changes are relatively rare. Vehicles go through refreshes every few years, as the Model 3 and Model Y did earlier this year. However, the Cybertruck is one of the vehicles that has not changed much since its launch in late 2023, but it has gone through some minor changes.
Most recently, Wes Morrill, the Cybertruck program’s Lead Engineer, stated that the company had made a minor change to the casting of the all-electric pickup for manufacturing purposes. This change took place in April:
We made a minor change on the casting for manufacturability in April. Our Internal testing shows no difference in crash result but IIHS only officially tested the latest version
— Wes (@wmorrill3) December 17, 2025
The change is among the most subtle that can be made, but it makes a massive difference in manufacturing efficiency, build quality, and scalability.
Morrill revealed Tesla’s internal testing showed no difference in crash testing results performed by the IIHS.
The 2025 Cybertruck received stellar ratings in each of the required testing scenarios and categories. The Top Safety Pick+ award is only given if it excels in rigorous crash tests. This requires ‘Good’ ratings in updated small and moderate overlap front, side, roof, and head restraints.
Additionally, it must have advanced front crash prevention in both day and night. Most importantly, the vehicle must have a ‘Good’ or ‘Acceptable’ headlights standard on all trims, with the “+ ” specifically demanding the toughest new updated moderate overlap test that checks rear-seat passenger protection alongside driver safety.

Tesla enters interesting situation with Full Self-Driving in California
Tesla has entered an interesting situation with its Full Self-Driving suite in California, as the State’s Department of Motor Vehicles had adopted an order for a suspension of the company’s sales license, but it immediately put it on hold.
The company has been granted a reprieve as the DMV is giving Tesla an opportunity to “remedy the situation.” After the suspension was recommended for 30 days as a penalty, the DMV said it would give Tesla 90 days to allow the company to come into compliance.
The DMV is accusing Tesla of misleading consumers by using words like Autopilot and Full Self-Driving on its advanced driver assistance (ADAS) features.
The State’s DMV Director, Steve Gordon, said that he hoped “Tesla will find a way to get these misleading statements corrected.” However, Tesla responded to the story on Tuesday, stating that this was a “consumer protection” order for the company using the term Autopilot.
It said “not one single customer came forward to say there’s a problem.” It added that “sales in California will continue uninterrupted.”
This was a “consumer protection” order about the use of the term “Autopilot” in a case where not one single customer came forward to say there’s a problem.
Sales in California will continue uninterrupted.

Tesla has used the terms Autopilot and Full Self-Driving for years, but has added the term “(Supervised)” to the end of the FSD suite, hoping to remedy some of the potential issues that regulators in various areas might have with the labeling of the program.
It might not be too long before Tesla stops catching flak for using the Full Self-Driving name to describe its platform.
Tesla Robotaxi goes driverless as Musk confirms Safety Monitor removal testing
The Robotaxi suite has continued to improve, and this week, vehicles were spotted in Austin without any occupants. CEO Elon Musk would later confirm that Tesla had started testing driverless rides in Austin, hoping to launch rides without any supervision by the end of the year.
Investor's Corner
Tesla stock closes at all-time high on heels of Robotaxi progress
Tesla stock (NASDAQ: TSLA) closed at an all-time high on Tuesday, jumping over 3 percent during the day and finishing at $489.88.
The price beats the previous record close, which was $479.86.
Shares have had a crazy year, dipping more than 40 percent from the start of the year. The stock then started to recover once again around late April, when its price started to climb back up from the low $200 level.
This week, Tesla started to climb toward its highest levels ever, as it was revealed on Sunday that the company was testing driverless Robotaxis in Austin. The spike in value pushed the company’s valuation to $1.63 trillion.
Tesla Robotaxi goes driverless as Musk confirms Safety Monitor removal testing
It is the seventh-most valuable company on the market currently, trailing Nvidia, Apple, Alphabet (Google), Microsoft, Amazon, and Meta.
Shares closed up $14.57 today, up over 3 percent.
The stock has gone through a lot this year, as previously mentioned. Shares tumbled in Q1 due to CEO Elon Musk’s involvement with the Department of Government Efficiency (DOGE), which pulled his attention away from his companies and left a major overhang on their valuations.
However, things started to rebound halfway through the year, and as the government started to phase out the $7,500 tax credit, demand spiked as consumers tried to take advantage of it.
Q3 deliveries were the highest in company history, and Tesla responded to the loss of the tax credit with the launch of the Model 3 and Model Y Standard.
Additionally, analysts have announced high expectations this week for the company on Wall Street as Robotaxi continues to be the focus. With autonomy within Tesla’s sights, things are moving in the direction of Robotaxi being a major catalyst for growth on the Street in the coming year.
