Tesla CEO Elon Musk will be adding more specifics to the recently-released Master Plan Part IV. Musk shared the update on social media platform X amidst conversations about the general nature of the Master Plan Part IV. 

In a conversation on X, Musk responded to a post from Tesla retail shareholder and bull Dave Lee, who observed that the currently released Master Plan Part IV could really just be the introduction to the real plan due to its absence of specifics.

Elon Musk responded, stating that he would be adding specifics to the plan in a later update. “Fair enough. Will add more specifics,” Musk wrote in his post.

Tesla has been following Elon Musk’s Master Plans for decades. The first Master Plan, released in 2006, outlined the company’s path from the original Tesla Roadster to the Model 3, as well as the first steps for Tesla Energy. Master Plan Part Deux, released in 2016, covered the ramp of Tesla Energy, the expansion of Tesla’s vehicle lineup, and the rollout of a Robotaxi service.

Master Plan Part 3 was more ambitious as it was generally an in-depth proposal for achieving a global sustainable entry economy by transitioning to electricity-powered vehicles, homes, and industry, which will, in turn, be powered by renewable energy sources like solar and wind. Master Plan Part 3 also included a five-step plan to accomplish this, allowing the world to transition to a fully electrified future. 

Master Plan Part IV, which was released a few days ago, focused on automation and artificial intelligence to achieve sustainable abundance. But while the first two Master Plans were very clear and specific and Master Plan Part 3 was very in-depth, Master Plan Part IV was quite general and vague in comparison. It was easy to tell that Optimus would play a big role in the pursuit of sustainable abundance, but apart from that, there were no specifics as to how Tesla intended to achieve its goals.

Fortunately, these specifics would be discussed by Musk in a later update to the plan.

Tesla CEO Elon Musk has not shied away from the idea that the company’s value is not reliant on its performance as an automaker.

That idea is even more prudent in today’s landscape than ever, especially as Tesla leans more on its prowess as an AI, autonomy, and robotics company rather than one that just makes electric cars.

Musk solidified that point on Monday, as he revealed that he believes the vast majority of Tesla’s valuation will rely on a project that the company has been developing for several years.

The CEO has long discussed how robotics will revolutionize the labor landscape in factories, households, and other workplaces.

He believes Optimus, as it is rolled out in the coming years, will truly take over as the main contributor to Tesla’s valuation, being worth about 80 percent of the company’s total market cap:

Those are the biggest factors.

~80% of Tesla’s value will be Optimus.

This is a point Musk has previously discussed, but he has never listed a specific number in terms of what Optimus could mean to Tesla. In the past, he’s mentioned Optimus’s ability to generate long-term revenue potential, its value to the company, and its impact on the market overall.

Musk has said Optimus has the potential to be worth over $10 trillion in revenue:

“It’s one of those things where I think long term, Optimus will be — Optimus has the potential to be north of $10 trillion in revenue, like it’s really bananas. So, that, you can obviously afford a lot of training compute in that situation. In fact, even $500 billion training compute in that situation would be quite a good deal.”

Optimus has been a main point of discussion amongst analysts who cover the company. Piper Sandler recently released a note that said “Optimus should be moving/staging parts within Tesla’s facilities” by this time next year.

Analysts also said that Optimus could be a major benefit for companies to bring in to handle tedious tasks in manufacturing settings. If it is able to work 18-hour shifts, the firm believes Tesla could price it at $100,000 per unit.

Other firms, like Morgan Stanley, have said Tesla could replace its own staff by 10 percent with Optimus, saving the company $2.5 billion.

SpaceX CEO Elon Musk recently shared an insane feat accomplished by Starship’s upper stage during its tenth test flight.

Despite the challenges it faced during its return trip to Earth, Flight 10’s Starship upper stage demonstrated impressive accuracy when it came to its target landing zone.

Against the odds

Musk’s update was shared on social media platform X. In a conversation about Starship upper stage’s return to Earth, Musk revealed that the upper stage splashed down just 3 meters (under 10 feet) from its intended target. Considering the size of the Starship upper stage and the ocean itself, achieving this accuracy was nothing short of insane.

Starship Flight 10 was a success as both the Super Heavy booster and Ship upper stage completed all their mission objectives. However, videos and images released by SpaceX showed the upper stage’s heat shield scorched golden-brown and parts of its aft skirt visibly missing. The flaps and other surfaces also bore signs of heavy stress from reentry.

SpaceX highlighted this in a post on X: “Starship made it through reentry with intentionally missing tiles, completed maneuvers to intentionally stress its flaps, had visible damage to its aft skirt and flaps, and still executed a flip and landing burn that placed it approximately 3 meters from its targeted splashdown point,” SpaceX noted.

A key milestone

The result stands in stark contrast to Starship’s earlier test flights this year, when all three prior upper-stage flights in 2025 ended in premature breakup before splashdown. Flight 10 not only marked the first successful splashdown of the year for the Starship upper stage, but it also delivered near-perfect precision despite its battered state, according to a Space.com report.

For SpaceX, this success is a critical proof point in developing a fully reusable launch system. A spacecraft capable of surviving severe reentry conditions and still landing within meters of its target underscores the robustness needed for future missions, including orbital payload deliveries and, eventually, landings on the Moon and Mars.
