After being sighted on Des Moines, IA on Thursday, the Tesla Semi has been spotted smoothly gliding through Colorado. The Semi was sighted at the Brush, CO Supercharger, where Tesla’s employees accompanying the truck answered questions about the vehicle while it was charging.

The Tesla Semi sighting was shared by recording engineer Erik J. Martin on Twitter. Martin’s posts, one of which was retweeted by the official Tesla Twitter account, featured the Semi as it was rolling into the Brush Supercharger station. Erik mentioned in a series of posts that he was informed that the prototype is the short-range version of the truck, with a range of 300 miles. The Tesla engineers accompanying the vehicle reportedly noted that the Semi was hand-built and that it was largely made of carbon fiber as well.

Being the short-range version of the electric truck, the Semi currently making its way across the United States is a daycab vehicle, though Tesla’s employees reportedly informed Martin that there would be a variant of the truck that would have space for sleeper features. Such features would be perfect for the long-range version of the electric truck, with drivers being able to take short naps while the Semi is charging at Tesla’s upcoming Megacharger network.

Also notable were the Semi’s cameras, of which there are 26 around the prototype. Tesla’s employees accompanying the Semi reportedly mentioned that there would likely be fewer cameras in the final iteration of the vehicle. Interestingly, while the Semi’s crew was very willing to address inquiries about the truck’s features, they were particularly secretive about the vehicle’s current charging system.

The Tesla Semi is designed to be supported by the upcoming Megacharger network, which is not operational yet. For now, the Semi is using Tesla’s current Supercharger network, though Erik noted that the engineers appeared to be using around 4-6 Superchargers to charge the all-electric Semi truck.

Tesla’s engineers also reportedly noted that so far, the only locations that have leaked the truck’s visit to their facilities were J.B. Hunt and UPS. This suggests that the Semi might have visited facilities of other reservation holders. One of these is Ruan Transportation Management Systems, which is based in Des Moines, IA. Ruan published a blog post about the Semi’s visit to their facility yesterday, even discussing some of the truck’s remote monitoring features.

“We will continue to be involved with the team at Tesla Motors as they introduce the trucks to the market,” said Cade. “We will work with them directly to ensure the vehicles will serve us and our customers to the level we both expect,” Ruan vice president of fleet services James Cade wrote in a blog post.

Tesla appears to be going full throttle in its efforts to refine the Semi before the vehicle enters production. The truck’s initial specs are already impressive, with its four Model 3-derived electric motors, its 0-60 mph time of 5 seconds flat, and its Class 8 hauling capacity. The Semi is also equipped with several key features, such as jackknife protection, near-infinite brake pads due to its powerful regenerative braking system, and Convoy Mode, a feature that allows the Semis to semi-autonomously draft in close proximity with each other, reducing energy usage from wind resistance.

SpaceX’s IPO might arrive sooner than you think

Musk has hinted for years that an eventual public offering was inevitable, though he has stressed the need to maintain operational focus. Insiders have told outlets that the CEO is pushing for a significant retail investor allocation, reportedly more than 20 percent of shares, and tighter lock-up periods to limit early selling pressure.

Elon Musk’s SpaceX is on the verge of one of the most anticipated Initial Public Offerings (IPO) in history.

However, a new report from The Information indicates the rocket and satellite giant is aiming to file its IPO prospectus with U.S. regulators as soon as this week, or early next week at the latest.

People familiar with the plans told The Information that advisers involved in the process expect the IPO could raise more than 75 billion dollars, potentially making it the largest stock market debut ever and eclipsing Saudi Aramco’s 29.4 billion dollar offering in 2019.

The filing would mark the formal start of what has long been rumored: SpaceX’s transition from a closely held private powerhouse to a publicly traded company.

The timing aligns with earlier signals.

In late February, Bloomberg reported that SpaceX was targeting a confidential IPO filing in March and a possible public listing in June, with a valuation north of 1.75 trillion dollars. At the time, the company’s private valuation hovered around 1.25 trillion dollars.

Starlink, SpaceX’s satellite internet constellation, has been the primary driver of that surge, now serving millions of customers worldwide and generating steady revenue. Recent Starship test flights and a record pace of Falcon launches have further bolstered investor confidence.

Musk has hinted for years that an eventual public offering was inevitable, though he has stressed the need to maintain operational focus. Insiders have told outlets that the CEO is pushing for a significant retail investor allocation, reportedly more than 20 percent of shares, and tighter lock-up periods to limit early selling pressure.

A June listing would give SpaceX immediate access to public capital markets at a moment when demand for space-related stocks remains high. It would also allow early employees and long-time investors to cash out portions of their stakes while giving everyday shareholders a chance to own a piece of the company behind reusable rockets, global broadband, and NASA contracts.

Of course, nothing is certain until the SEC filing appears. Market conditions, regulatory reviews, and Musk’s own schedule could still shift timelines.

Yet the latest word from The Information suggests the window has opened. If the filing lands this week, SpaceX’s roadshow could begin in earnest within weeks, setting the stage for what many analysts already call the IPO of the decade.

Elon Musk hints what Tesla’s new vehicle will be

After Musk’s post earlier this week, many considered the possibility that the Tesla CEO was potentially talking about the Roadster, which is slated for an unveiling (again) next month. Some considered the possibility of the Robovan, which was unveiled back in 2024.

Elon Musk hinted at what Tesla’s new vehicle will be just a day or so after he essentially confirmed the company is developing something that will eventually be available for consumers.

Earlier this week, Musk said that something “way cooler than a minivan” was on the way from Tesla after a fan posted on X that the company needed to build something for larger families. Requesting this type of vehicle has been a move of many Tesla fans over the years, but now, the urgency is even higher for this type of car because of the company’s decision to sunset the Model X.

Following reports of Musk’s plans to build something that will be cooler than a minivan, speculation consisted of what could possibly be on the way.

Tesla has teased a CyberSUV for quite a while, and there were even some clay models built by the company that were strategically placed in a promotional video.

After Musk’s post earlier this week, many considered the possibility that the Tesla CEO was potentially talking about the Roadster, which is slated for an unveiling (again) next month. Some considered the possibility of the Robovan, which was unveiled back in 2024.

However, a new post from Musk seems to indicate that it will be a new project altogether. After one follower of Musk’s said:

“If Tesla makes a car with 3 rows of seats, each with its own pair of doors so nobody has to climb over anybody else to get to their seat, they will create a baby boom the likes of which we haven’t seen in 80 years.”

Musk’s reply was simple but definitely shed more insight into the company’s plans, as he said:

“Noted.”

Musk’s simple one-word answer might be enough to essentially expect something large, like a full-sized SUV. This would be an incredible addition to the Tesla lineup, especially as the Model X is going away.

Even the Model X is not quite big enough, and not comparable to vehicles like the Chevrolet Tahoe, so a three-row, six-door SUV might be exactly what Tesla fans want.

It certainly does not sound like Tesla is planning to launch the Model Y L in the U.S., at least not exclusively, or use that car, which is currently built in China, to solve the needs of a larger family.

Tesla gives big hint that it will build Cyber SUV, smaller Cybertruck

It seems the time has certainly come for Tesla to answer the call of what consumers want. This has long been requested, and although the company’s sights are ultimately set on achieving full autonomy, there is still a need for larger families, and a full-size SUV could be a great addition for Tesla as it moves into the second quarter of 2026.

Tesla’s newest “Folding V4 Superchargers” are key to its most aggressive expansion yet

Tesla’s folding V4 Supercharger ships 33% more per truck, cuts deployment time and cost significantly.

Tesla V4 Supercharger installation ramping in Europe

Tesla is rolling out a folding V4 Supercharger design, an engineering change that allows 33% more units to fit on a single delivery truck, cuts deployment time in half, and reduces overall installation cost by roughly 20%.

The folding mechanism addresses one of the least glamorous but most consequential bottlenecks in charging infrastructure: getting hardware from factory floor to job site efficiently. By collapsing the form factor for transit and unfolding into an operational configuration on arrival, the new design dramatically reduces the logistics overhead that has historically slowed Supercharger rollouts, particularly at large or remote sites where multiple units are needed simultaneously.

The timing aligns with a broader acceleration in Tesla’s network strategy. In March 2026, Tesla’s Gigafactory New York produced its final V3 Supercharger cabinet after more than seven years and 15,000 units, pivoting entirely to V4 cabinet production. The V4 cabinet itself is already a generational leap, delivering up to 500 kW per stall for passenger vehicles and up to 1.2 MW for the Tesla Semi, while supporting twice the stalls per cabinet at three times the power density of its predecessor. The folding transport innovation layers logistical efficiency on top of that technical foundation.

Tesla Charging’s Director Max de Zegher, commenting on the V4 cabinet when it launched, captured the operational philosophy behind these changes: “Posts can peak up to 500kW for cars, but we need less than 1MW across 8 posts to deliver maximum power to cars 99% of the time.” The design philosophy has always been about maximizing real-world throughput, not just peak specs, and the folding transport upgrade extends that thinking into the supply chain itself.
