SpaceX on track to become third most valuable private company in the world
SpaceX is on track to become the third most valuable private company in the world if it successfully raises a new round of funding.
First reported and confirmed by CNBC, SpaceX hopes to raise between $500 million and $1 billion via a new investment offering. The Series N round would ultimately value the company at $44 billion – second only to China’s Didi and Bytedance (known in the US for TikTok) – if SpaceX finds significant investor interest at the upgraded $270 share price. Based on the ~$3.4 billion SpaceX has raised over more than a dozen rounds in just the last several years, strong investor demand is all but guaranteed.
The confidence and interest of investors can be explained in large part by SpaceX’s spectacular success in the face of countless systemic and technological challenges, as well as its association with founder and Tesla CEO Elon Musk. Perhaps even more at odds with success than SpaceX’s near-term goals, Tesla’s meteoric rise and iron grip on the global consumer electric vehicle industry has unsurprisingly helped convince many that success is often just a matter of time for Musk’s calculated ventures.
Like several recent fundraising rounds, SpaceX is seeking investors willing to support the company’s long-term vision in the hopes that its Starship and Starlink programs will be as disruptive and revolutionary as they aim to be. CNBC reports that SpaceX is telling prospective investors that Starlink aims to become a major player in a range of industries with a potential global market of more than $1 trillion per year. That figure is almost certainly a best-case theoretical value assuming that SpaceX has completed a vast ~40,000-satellite Starlink constellation and is able to capture almost every single prospective customer.
It’s still within the realm of possibility, though. On its own, Starlink holds the potential to become one of the largest companies in the world – public or private – if SpaceX achieves every ambitious goal it’s set itself to. In that context, there’s a chance that acquiring a stake in SpaceX at a valuation of ~$44 billion will set investors up for unprecedented returns on the order of Tesla investors buying shares for $100-200 in the early 2010s.
Of course, that investment rationale doesn’t even touch on Starship, aside from the fact that Starship will be a necessity if SpaceX is to have any chance of launching and maintaining a constellation of tens of thousands of satellites. Beyond the Starship/Super Heavy launch vehicle’s integral role in future plans for Starlink, the next-generation rocket is arguably a much thornier technical challenge than Starlink while also offering far less return-on-investment (ROI) certainty. Relative to other industries, particularly those with demand for communications services, the global demand for commercial launch services is minuscule, representing just a few billion dollars per year.
Even if Falcon 9 – let alone Starship – dramatically cuts the cost of access to orbit, there’s no guarantee beyond basic economic theory that lowering the barrier to entry will necessarily expand the market for launches. For a radical expansion in demand, entire new space-adjacent industries will have to be created given that the vast majority of modern demand comes from space-based communications companies.
SpaceX has known that this would be the case for at least half a decade, however, and is thus intelligently positioning Starlink as a primary investor focus as far as revenue and profit are concerned. Starlink would thus help SpaceX complete the Starship launch vehicle, which is far more focused on the company’s foundational goal of making humanity a multiplanetary species by enabling the creation of a self-sustaining city on Mars. Still, Starship will need to be revolutionarily affordable, reliable, and reusable for SpaceX to ever even dream of achieving that founding goal.
In the process of tackling those technical challenges, Starship could very well expand the global space industry by one or several magnitudes, but it will remain a major wildcard up until the day it does.

Tesla confirms that it finally solved its 4680 battery’s dry cathode process
The suggests the company has finally resolved one of the most challenging aspects of its next-generation battery cells.
Tesla has confirmed that it is now producing both the anode and cathode of its 4680 battery cells using a dry-electrode process, marking a key breakthrough in a technology the company has been working to industrialize for years.
The update, disclosed in Tesla’s Q4 and FY 2025 update letter, suggests the company has finally resolved one of the most challenging aspects of its next-generation battery cells.
Dry cathode 4680 cells
In its Q4 and FY 2025 update letter, Tesla stated that it is now producing 4680 cells whose anode and cathode were produced during the dry electrode process. The confirmation addresses long-standing questions around whether Tesla could bring its dry cathode process into sustained production.
The disclosure was highlighted on X by Bonne Eggleston, Tesla’s Vice President of 4680 batteries, who wrote that “both electrodes use our dry process.”
Tesla first introduced the dry-electrode concept during its Battery Day presentation in 2020, pitching it as a way to simplify production, reduce factory footprint, lower costs, and improve energy density. While Tesla has been producing 4680 cells for some time, the company had previously relied on more conventional approaches for parts of the process, leading to questions about whether a full dry-electrode process could even be achieved.
4680 packs for Model Y
Tesla also revealed in its Q4 and FY 2025 Update Letter that it has begun producing battery packs for certain Model Y vehicles using its in-house 4680 cells. As per Tesla:
“We have begun to produce battery packs for certain Model Ys with our 4680 cells, unlocking an additional vector of supply to help navigate increasingly complex supply chain challenges caused by trade barriers and tariff risks.”
The timing is notable. With Tesla preparing to wind down Model S and Model X production, the Model Y and Model 3 are expected to account for an even larger share of the company’s vehicle output. Ensuring that the Model Y can be equipped with domestically produced 4680 battery packs gives Tesla greater flexibility to maintain production volumes in the United States, even as global battery supply chains face increasing complexity.

Tesla Giga Texas to feature massive Optimus V4 production line
This suggests that while the first Optimus line will be set up in the Fremont Factory, the real ramp of Optimus’ production will happen in Giga Texas.
Tesla will build Optimus 4 in Giga Texas, and its production line will be massive. This was, at least, as per recent comments by CEO Elon Musk on social media platform X.
Optimus 4 production
In response to a post on X which expressed surprise that Optimus will be produced in California, Musk stated that “Optimus 4 will be built in Texas at much higher volume.” This suggests that while the first Optimus line will be set up in the Fremont Factory, and while the line itself will be capable of producing 1 million humanoid robots per year, the real ramp of Optimus’ production will happen in Giga Texas.
This was not the first time that Elon Musk shared his plans for Optimus’ production at Gigafactory Texas. During the 2025 Annual Shareholder Meeting, he stated that Giga Texas’ Optimus line will produce 10 million units of the humanoid robot per year. He did not, however, state at the time that Giga Texas would produce Optimus V4.
“So we’re going to launch on the fastest production ramp of any product of any large complex manufactured product ever, starting with building a one-million-unit production line in Fremont. And that’s Line one. And then a ten million unit per year production line here,” Musk stated.
How big Optimus could become
During Tesla’s Q4 and FY 2025 earnings call, Musk offered additional context on the potential of Optimus. While he stated that the ramp of Optimus’ production will be deliberate at first, the humanoid robot itself will have the potential to change the world.
“Optimus really will be a general-purpose robot that can learn by observing human behavior. You can demonstrate a task or verbally describe a task or show it a task. Even show it a video, it will be able to do that task. It’s going to be a very capable robot. I think long-term Optimus will have a very significant impact on the US GDP.
“It will actually move the needle on US GDP significantly. In conclusion, there are still many who doubt our ambitions for creating amazing abundance. We are confident it can be done, and we are making the right moves technologically to ensure that it does. Tesla, Inc. has never been a company to shy away from solving the hardest problems,” Musk stated.

Rumored SpaceX-xAI merger gets apparent confirmation from Elon Musk
The comment follows reports that the rocket maker is weighing a transaction that could further consolidate Musk’s space and AI ventures.
Elon Musk appeared to confirm reports that SpaceX is exploring a potential merger with artificial intelligence startup xAI by responding positively to a post about the reported transaction on X.
Musk’s comment follows reports that the rocket maker is weighing a transaction that could further consolidate his space and AI ventures.
SpaceX xAI merger
As per a recent Reuters report, SpaceX has held discussions about merging with xAI, with the proposed structure potentially involving an exchange of xAI shares for SpaceX stock. The value, structure, and timing of any deal have not been finalized, and no agreement has been signed.
Musk appeared to acknowledge the report in a brief reply on X, responding “Yeah” to a post that described SpaceX as a future “Dyson Swarm company.” The comment references a Dyson Swarm, a sci-fi megastructure concept that consists of a massive network of satellites or structures that orbit a celestial body to harness its energy.
Reuters noted that two entities were formed in Nevada on January 21 to facilitate a potential transaction for the possible SpaceX-xAI merger. The discussions remain ongoing, and a transaction is not yet guaranteed, however.
AI and space infrastructure
A potential merger with xAI would align with Musk’s stated strategy of integrating artificial intelligence development with space-based systems. Musk has previously said that space-based infrastructure could support large-scale computing by leveraging continuous solar energy, an approach he has framed as economically scalable over time.
xAI already has operational ties to Musk’s other companies. The startup develops Grok, a large language model that holds a U.S. Department of Defense contract valued at up to $200 million. AI also plays a central role in SpaceX’s Starlink and Starshield satellite programs, which rely on automation and machine learning for network management and national security applications.
Musk has previously consolidated his businesses through share-based transactions, including Tesla’s acquisition of SolarCity in 2016 and xAI’s acquisition of X last year. Bloomberg has also claimed that Musk is considering a merger between SpaceX and Tesla in the future.
