Elon Musk stands by Tesla Semi and rebuts Bill Gates’ critique: ‘He has no clue’
Earlier this month, tech visionary and Microsoft co-founder Bill Gates penned a blog post outlining his stance on the next generation of transportation. And while Gates was supportive of all-electric cars, he maintained that some types of vehicles, such as heavy-duty machinery like 18-wheelers, will never really work out if they were just powered by batteries.
Instead, Gates explained that other technologies such as cheap alternative fuels would work better for tasks like long-haul travel. The Microsoft co-founder mentioned biofuels and electrofuels as superior alternatives to battery-electric heavy-duty machines, partly due to their compatibility with the trucks that are already operating today.
“The problem is that batteries are big and heavy. The more weight you’re trying to move, the more batteries you need to power the vehicle. But the more batteries you use, the more weight you add—and the more power you need. Even with big breakthroughs in battery technology, electric vehicles will probably never be a practical solution for things like 18-wheelers, cargo ships, and passenger jets. Electricity works when you need to cover short distances, but we need a different solution for heavy, long-haul vehicles,” Gates wrote.
Elon Musk, for his part, recently shared his stance on Gates’ recent statement. When asked on Twitter about his thoughts on the Microsoft co-founder’s points about batteries and long-haul trucking, the Tesla CEO offered a quick, direct rebuttal. “He has no clue,” he wrote.
Inasmuch as Musk’s statement is direct, the Tesla CEO’s rebuttal may very well prove to be a key argument for battery-electric long-haul trucks. Tesla, after all, has been obsessively improving its battery tech over the years, and the results of all this work are expected to be discussed in the upcoming Battery Day event. The event, which will be held this September 22, 2020, is expected to feature a thorough discussion about Tesla’s next-generation battery cells, which would likely be pivotal to the release of even more impressive, breakthrough vehicles and energy products.
Tesla’s next vehicles like the Plaid Model S, Model X, Semi, and Cybertruck, for example, are all speculated to be fitted with the company’s next-generation cells. And Tesla being the way it is, there is a very good chance that the electric car maker will not stop with the technology it will unveil on Battery Day. Innovations will continue, work on more advanced cells will be done, recycling will be emphasized, and batteries will get even better over time. Elon Musk, for his part, has stated that 400 Wh/kg batteries with high cycle life and ready for mass production are potentially just 3 to 4 years away, and based on his previous statements, 400 Wh/kg is the point where all-electric flights could be made possible.
Ultimately, Musk and Gates’ opposing views on electric long-haulers like the Tesla Semi would likely be decided by the performance of the vehicle itself when it gets released. Fortunately, it appears that the market does not need to wait very long, seeing as Elon Musk has noted that the Semi is already poised to enter volume production. If the Semi gets embraced by long-haul companies due to its affordable operating cost, performance, and tech, and if its capabilities prove better than those announced in its unveiling, the vehicle could end up being a Class 8 humbling device for the Microsoft co-founder.

Tesla Q4 delivery numbers are better than they initially look: analyst
The Deepwater Asset Management Managing Partner shared his thoughts in a post on his website.
Longtime Tesla analyst and Deepwater Asset Management Managing Partner Gene Munster has shared his insights on Tesla’s Q4 2025 deliveries. As per the analyst, Tesla’s numbers are actually better than they first appear.
Munster shared his thoughts in a post on his website.
Normalized December Deliveries
Munster noted that Tesla delivered 418k vehicles in the fourth quarter of 2025, slightly below Street expectations of 420k but above the whisper number of 415k. Tesla’s reported 16% year-over-year decline, compared to +7% in September, is largely distorted by the timing of the tax credit expiration, which pulled forward demand.
“Taking a step back, we believe September deliveries pulled forward approximately 55k units that would have otherwise occurred in December or March. For simplicity, we assume the entire pull-forward impacted the December quarter. Under this assumption, September growth would have been down ~5% absent the 55k pull-forward, a Deepwater estimate tied to the credit’s expiration.
“For December deliveries to have declined ~5% year over year would imply total deliveries of roughly 470k. Subtracting the 55k units pulled into September results in an implied December delivery figure of approximately 415k. The reported 418k suggests that, when normalizing for the tax credit timing, quarter-over-quarter growth has been consistently down ~5%. Importantly, this ~5% decline represents an improvement from the ~13% declines seen in both the March and June 2025 quarters.“
Tesla’s United States market share
Munster also estimated that Q4 as a whole might very well show a notable improvement in Tesla’s market share in the United States.
“Over the past couple of years, based on data from Cox Automotive, Tesla has been losing U.S. EV market share, declining to just under 50%. Based on data for October and November, Cox estimates that total U.S. EV sales were down approximately 35%, compared to Tesla’s just reported down 16% for the full quarter. For the first two months of the quarter, Cox reported Tesla market share of roughly a 65% share, up from under 50% in the September quarter.
“While this data excludes December, the quarter as a whole is likely to show a material improvement in Tesla’s U.S. EV market share.“

Tesla analyst breaks down delivery report: ‘A step in the right direction’
“This will be viewed as better than feared deliveries and a step in the right direction for the Tesla story heading into 2026,” Ives wrote.
Tesla analyst Dan Ives of Wedbush released a new note on Friday morning just after the company released production and delivery figures for Q4 and the full year of 2025, stating that the numbers, while slightly underwhelming, are “better than feared” and as “a step in the right direction.”
Tesla reported production of 434,358 and deliveries of 418,227 for the fourth quarter, while 1,654,667 vehicles were produced and 1,636,129 cars were delivered for the full year.
Tesla releases Q4 and FY 2025 vehicle delivery and production report
Interestingly, the company posted its own consensus figures that were compiled from various firms on its website a few days ago, where expectations were set at 1,640,752 cars for the year. Tesla fell about 4,000 units short of that. One of the areas where Tesla excelled was energy deployments, which totaled 46.7 GWh for the year.
🚨 Wedbush’s Dan Ives has released a new note on Tesla $TSLA:
“Tesla announced its FY4Q25 delivery numbers this morning coming in at 418.2k vehicles slightly below the company’s consensus delivery estimate of 422.9k but much better than the whisper numbers of ~410k as the…

In terms of vehicle deliveries, Ives writes that Tesla certainly has some things to work through if it wants to return to growth in that aspect, especially with the loss of the $7,500 tax credit in the U.S. and “continuous headwinds” for the company in Europe.
However, Ives also believes that, given the delivery numbers, which were on par with expectations, Tesla is positioned well for a strong 2026, especially with its AI focus, Robotaxi and Cybercab development, and energy:
“This will be viewed as better than feared deliveries and a step in the right direction for the Tesla story heading into 2026. We look forward to hearing more at the company’s 4Q25 call on January 28th. AI Valuation – The Focus Throughout 2026. We believe Tesla could reach a $2 trillion market cap over the coming year and, in a bull case scenario, $3 trillion by the end of 2026…as full-scale volume production begins with the autonomous and robotics roadmap…The company has started to test the all-important Cybercab in Austin over the past few weeks, which is an incremental step towards launching in 2026 with important volume production of Cybercabs starting in April/May, which remains the golden goose in unlocking TSLA’s AI valuation.”
It’s no secret that for the past several years, Tesla’s vehicle delivery numbers have been the main focus of investors and analysts have looked at them as an indicator of company health to a certain extent. The problem with that narrative in 2025 and 2026 is that Tesla is now focusing more on the deployment of Full Self-Driving, its Optimus project, AI development, and Cybercab.
While vehicle deliveries still hold importance, it is more crucial to note that Tesla’s overall environment as a business relies on much more than just how many cars are purchased. That metric, to a certain extent, is fading in importance in the grand scheme of things, but it will never totally disappear.
Ives and Wedbush maintained their $600 price target and an ‘Outperform’ rating on the stock.
