Tesla may just have figured out the perfect way to bolster its charging infrastructure during the holidays, a time when more drivers are taking long trips and relying on the company’s Supercharger Network. Based on images and videos captured by the Tesla community, it appears that the electric car maker has started deploying Mobile Supercharger units that are powered by Megapack batteries, which are then installed on a trailer. 

This setup allows Tesla to instantly add more charging stalls at a specific location. One of these Megapack-powered chargers was spotted in San Luis Obispo (SLO) at the Madonna Inn Supercharger. Looking at the photographs of Tesla’s setup from EV enthusiast Brian Swenson, the Megapack appears to be hooked up to eight Urban Supercharger stalls that are set up on the trailer itself.  

Quite interestingly, the Mobile Supercharger stalls are reportedly capable of providing up to 125 kW of dedicated power. This makes them comparable to the previous output of Tesla’s V2 network before it was improved by the electric car maker to allow peak charge rates of up to 150 kW. Regardless, 125 kW is not inconvenient at all, especially for drivers who wish to take a coffee break in the middle of a long drive. 

A video recorded by Tesla owner-enthusiast Shelly Fraval included a brief conversation with one of the electric car maker’s staff who happened to be with the Mobile Supercharger. According to the Tesla employee, the Megapack-powered Mobile Superchargers are being deployed by the company as a way to help owners during holidays such as Thanksgiving. In the Madonna Inn Supercharger, for example, wait times reached almost one hour last year during the holidays, but with the Mobile Supercharger in place, these wait times are expected to decrease to just minutes.

The deployment of Tesla’s Megapack-powered Mobile Superchargers holds a lot of potential for the company. Such solutions, after all, are perfect for events such as concerts, sports events, and even calamities such as fires and hurricanes. Even if the grid were to go down unexpectedly, Tesla would be able to deploy a mobile charging system to owners across the country. This, of course, would most certainly benefit Tesla owners all over. 

Tesla’s Megapack-powered Mobile Supercharger units will likely be more and more helpful in the coming quarters, particularly as the company starts delivering its most high-volume vehicle to date: the Model Y crossover. Once that vehicle is on the market, there is a very good chance that even Tesla’s expansive Supercharger Network would be utilized to its limits just to meet the demand from Model 3 and Model Y owners. During such instances, the Megapack-powered Mobile Superchargers would definitely be an ace for the company.

Tesla has expanded its Semi pilot program to a new region, as it has made it to Texas to be tested by logistics from Mone Transport. With the Semi entering production this year, Tesla is getting even more valuable data regarding the vehicle and its efficiency, which will help companies cut expenditures.

Mone Transport operates in Texas and on the Southern border, and it specializes in cross-border U.S.-Mexico freight operations. After completing some rigorous testing, Mone shared public results, which stand out when compared to efficiency metrics offered by diesel vehicles.

“Mone Transport recently had the opportunity to put the Tesla Semi to the test, and we’re thrilled with the results! Over 4,700 miles of operations at 1.64 kWh/mile in our Texas operation. We’re committed to providing zero-emission transportation to our customers!” the company said in a post on X.

Mone said the Tesla Semi it put into its fleet for this test recorded 1.64 kWh per mile efficiency, beating Tesla’s official 1.7 kWh per mile target and delivering a massive leap over conventional diesel trucks.

Comparable Class 8 diesel semis, typically achieving 6-7 miles per gallon, consume roughly 5.5 kWh per mile in energy-equivalent terms, meaning the Semi uses three to four times less energy while also producing zero tailpipe emissions.

Tesla Semi undergoes major redesign as dedicated factory preps for deliveries

The performance of the Tesla Semi in Mone Transport’s testing aligns with data from other participants in the pilot program. ArcBest’s ABF Freight Division logged 4,494 miles over three weeks in 2025, averaging 1.55 kWh per mile across varied routes, including a grueling 7,200-foot Donner Pass climb. The truck “generally matched the performance of its diesel counterparts,” the carrier said.

PepsiCo, which operates the largest known Semi fleet, recorded 1.7 kWh per mile in North American Council for Freight Efficiency testing. Additional pilots showed similar gains: DHL hit 1.72 kWh per mile, and Saia achieved 1.73 kWh per mile.

These metrics underscore the Semi’s ability to slash operating costs through superior efficiency, lower maintenance, and zero-emission operation. As charging infrastructure scales and production ramps toward 2026 targets, participants like Mone Transport are proving electric semis can seamlessly integrate into freight networks, accelerating the industry’s shift to sustainable, high-performance trucking.

Tesla continues to prep for a more widespread presence of the Semi in the coming months as it recently launched the first public Semi Megacharger site in Los Angeles. It is working on building out infrastructure for regional runs on the West Coast initially, with plans to expand this to the other end of the country in the coming years.

Elon Musk’s SpaceX is reportedly leaning toward listing its shares on the Nasdaq for a potential initial public offering (IPO) that could become the largest in history. 

As per a recent report, the company is reportedly seeking early inclusion in the Nasdaq-100 index. The update was reported by Reuters, citing people familiar with the matter.

According to the publication, SpaceX is considering Nasdaq as the venue for its eventual IPO, though the New York Stock Exchange is also competing for the listing. Neither exchange has reportedly been informed of a final decision.

Reuters has previously reported that SpaceX could pursue an IPO as early as June, though the company’s plans could still change.

One of the publication’s sources also suggested that SpaceX is targeting a valuation of about $1.75 trillion for its IPO. At that level, the company would rank among the largest publicly traded firms in the United States by market capitalization.

Nasdaq has proposed a rule change that could accelerate the inclusion of newly listed megacap companies into the Nasdaq-100 index.

Under the proposed “Fast Entry” rule, a newly listed company could qualify for the index in less than a month if its market capitalization ranks among the top 40 companies already included in the Nasdaq-100.

If SpaceX is successful in achieving its target valuation of $1.75 trillion, it would become the sixth-largest company by market value in the United States, at least based on recent share prices.

Newly listed companies typically have to wait up to a year before becoming eligible for major indexes such as the Nasdaq-100 or S&P 500.

Inclusion in a major index can significantly broaden a company’s shareholder base because many institutional investors purchase shares through index-tracking funds.

According to Reuters, Nasdaq’s proposed fast-track rule is partly intended to attract highly valued private companies such as SpaceX, OpenAI, and Anthropic to list on the exchange.

The Boring Company announced that its Prufrock-2 tunnel boring machine (TBM) has completed another Vegas Loop tunnel in Las Vegas. The company shared the update in a post on social media platform X.

According to The Boring Company’s post, the new tunnel measures 2.28 miles, making it the company’s longest single Vegas Loop tunnel to date.

The new tunnel marks the fourth tunnel constructed near Westgate Las Vegas as the Vegas Loop network continues expanding across the city.

The Boring Company also noted that the new tunnel surpassed its previous internal record of 2.26 miles for a single Vegas Loop segment.

Construction of the tunnel involved moving roughly 68,000 cubic yards of dirt. The excavation process also used about 4.8 miles of continuous conveyor belt, powered by six motors totaling 825 horsepower.

The Boring Company’s Prufrock-series all-electric tunnel boring machines are designed to support the rapid expansion of company’s underground transportation projects, including the growing Vegas Loop network. Prufrock machines are designed for reusability, thanks in no small part to their capability to be deployed and retrieved easily through their “porposing” feature.

The Vegas Loop, specifically the Las Vegas Convention Center (LVCC) Loop segment, has already been used during major events. Most recently, the LVCC Loop supported the 2026 CONEXPO-CON/AGG construction trade show, which was held from March 3-7, 2026. 

As per The Boring Company, the LVCC Loop transported roughly 82,000 passengers across the convention center campus during the event’s duration.
