Update: Shortly after publishing, SpaceX began a much more ambitious series of tests with the Starship launch tower’s two main arms, which are designed to lift and (one day) catch Starships and Super Heavy boosters.
After lifting the arm carriage about 15m (~50 ft), several times higher than January 3rd’s far more conservative kickoff, SpaceX fired up each arm’s main hydraulic actuator and opened them about as wide as they’re able to move. Unsurprisingly, the arms’ first powered lateral movement happened very slowly, obviously telegraphing caution but probably also hinting at the start of a calibration process needed to determine their full range of motion and associate those positions with certain sensor readings or telemetry to ensure they can be safely controlled. As of midnight CST, that testing has continued well into the night.
Regardless of the purpose, substantial powered movement is a major milestone for the tower’s main arms and all but guarantees that more extensive tests and simulations are soon to come.
SpaceX has moved Starbase’s rocket-catching “chopstick” arms for the first time since they were installed on the orbital Starship pad’s ‘launch tower’ two months ago.
After a shockingly brisk three-month period of assembly, the first arm installed in late August 2021 was a lone structure designed to swing in; grab and stabilize Super Heavy with its claw; fuel and power Starship; and quickly detach and swing away from the rocket during launch. A month and a half later, SpaceX begin installing a much larger pair of more complex arms in mid-October. Unlike the Starship quick-disconnect (QD) arm, the pair of arms that followed were almost nothing like anything built as part of another rocket launch complex.
Unlike other ‘arms’ related to other rocket launch facilities, the pair SpaceX began to install on Starbase’s launch tower were colossal, measuring more than 30m (100+ ft) long and 5-10m (15-30 ft) tall. Built out of heavy-duty steel pipe and affixed to an even sturdier pair of claw-like supports that grab onto the launch tower, the combined assembly likely weighs hundreds of tons. Aside from their sheer scale, Starbase’s main tower arms are also attached to a complex system of cables and an industrial-strength ‘drawworks’ commonly used on giant oil rigs and derricks.
They also feature huge actuators that allow the two arms to open and close, revealing a bit of their purpose. While the main reason they likely exist is to provide SpaceX with an all-weather alternative to cranes for lifting, manipulating, and precisely stacking Starships and Super Heavy boosters at the launch pad, the headline – ever since Musk revealed the idea – has always been plans to use those same arms to literally catch rockets out of mid-air.
To do so, they’ll need to be able to actuate and move extremely quickly and precisely up and down the Starship launch tower, matching the velocity and autonomously determining the position of landing Super Heavy boosters (and possibly Starships) to avoid major damage or the loss of entire vehicles. While arguably an unnecessary gamble and an attempt to micro-optimize the concept of operations of a rocket that’s yet to attempt a single orbital-class launch, SpaceX’s CEO is clearly committed to the idea and – whether or not the first iteration works – has fully delivered on the first complete lift-and-catch system.
On January 3rd, 2022, after removing a large amount of scaffolding in the days prior, SpaceX briefly and slightly moved the installed arms for the first time, using the drawworks to lift the entire arm-and-carriage assembly a few meters (~6 ft) up and down the tower. Once a few minor additional steps are taken, the chopsticks could be ready for much more extensive testing, beginning with basic lift, descent, and arm actuation tests to calibrate and then proof the first-of-its-kind mechanism. Later, SpaceX will likely simulate catching rockets in a wide range of scenarios. Somewhere before, during, or after that testing, SpaceX may perform another fit test with Starship S20 and Super Heavy B4 – but this time using the arms to lift and install the stages.

SpaceX’s amended S-1 is sparking a major Tesla merger conversation
A single line in SpaceX’s amended S-1 just sent Tesla stock down 5% in one day.
A single line buried in SpaceX’s amended S-1 filing is doing more to move Tesla’s stock price than anything Tesla itself has announced in months. The clause, disclosed as SpaceX prepares for what could be the largest IPO in Wall Street history, states that the company “may issue a significant amount of equity in connection with future transactions.” While this may be seen as boilerplate language in S-1 filings, the historical ties between SpaceX and Tesla, and with Elon Musk reportedly discussing a possible merger with close colleagues, investors are interpreting it as something closer to a signal.
The concern among institutional investors like Gary Black, managing director of The Future Fund, pointed directly to the amended filing on X, saying it “strongly suggests more SPCX equity will be issued,” which could potentially be used to acquire Tesla. He estimated such a deal could be 28% dilutive to Tesla shareholders since SpaceX would likely command a significantly higher valuation multiple. Black added that institutional investors he knows hate the idea of a combination because they prefer pure plays over conglomerates, which he said “nearly always gravitate to the lowest common multiple.”
The Tesla and SpaceX merger everyone is talking about is quietly building
The bull case runs the math differently. Tesla influencer and retail shareholder advocate AleXandra Merz pushed back on what she called a widespread misunderstanding of how merger-of-equals deals actually work. Rather than simply splitting the difference between two market caps, a merger exchange ratio is negotiated based on relative fair market values, meaning the lower valued company typically sees its stock reprice upward toward the deal value.
Under her model, SpaceX enters at a $2.5 trillion valuation and Tesla at $1.6 trillion, producing a combined entity worth $4.1 trillion split evenly between both shareholder groups. That implies Tesla’s side of the deal would be valued at $2.05 trillion, a gain of roughly $450 billion from its current market cap. She cited Dow-DuPont and CBS-Viacom as historical examples of how markets reprice both companies toward the announced exchange ratio after a deal is unveiled.

The SpaceX S-1 amendments also revealed just how much financial infrastructure already binds the two companies together. As Teslarati has reported, SpaceX purchased $697 million in Tesla Megapacks, $131 million in Cybertrucks, and the two companies have shared supply chain resources, and semiconductor fabrication plans since well before any merger conversation became public. A retail poll by Tesla influencer Sawyer Merritt is finding that 36% of respondents do not plan to buy SpaceX shares at IPO and 15.3% saying their decision depends on the valuation.

Whether the merger happens or not, the amended filing is seemingly moving markets and sharpened a debate that is no longer theoretical. SpaceX is weeks away from trading publicly, and Tesla shareholders are now watching every word of every filing for clues about what Musk plans to do next.
Elon Musk has firmly denied recent media reports suggesting that SpaceX has reduced its target valuation for an upcoming initial public offering.
The denial came directly from the SpaceX and Tesla frontman on his social media platform X, where he responded with a single word, “False,” to a post from ZeroHedge that cited Bloomberg sources.
This swift rebuttal underscores Musk’s ongoing effort to manage speculation surrounding one of the most anticipated market debuts in recent history.
False

According to the disputed reports, SpaceX had lowered its IPO valuation goal to at least $1.8 trillion from previous ambitions exceeding $2 trillion.
The claims emerged amid growing anticipation for the company’s confidential S-1 filing, which positions it for a potential public listing as early as June.
Some had pointed to strong revenue growth, particularly from the Starlink satellite internet service, which contributed heavily to the firm’s 2025 figures of $18.7 billion. Yet challenges persist in other areas, including substantial investments and losses tied to ambitious projects like Starship development and artificial intelligence initiatives, which plan to make life multiplanetary eventually.
Musk’s response highlights a pattern in which he actively counters what he views as inaccurate portrayals of his companies’ trajectories.
SpaceX, already valued privately at extraordinary levels, stands as a cornerstone of Musk’s empire alongside Tesla and xAI. The entrepreneur has long emphasized the transformative potential of reusable rockets and global broadband access, factors that fuel investor enthusiasm despite operational hurdles.
By rejecting the valuation downgrade narrative, Musk signals confidence in SpaceX’s fundamentals and its readiness for public markets on terms favorable to its long-term vision. People have been waiting a very long time to invest in SpaceX, and the valuation, as well as the introductory share price, is not going to need adjusting.
They’ll have plenty of suitors.
This episode reflects broader dynamics in the technology sector, where rumors often swirl around high-profile entities. Musk’s direct engagement with media narratives serves to maintain transparency and control the narrative around his ventures.
As SpaceX prepares for greater scrutiny in public markets, the founder’s denial reinforces optimism about its prospects. Supporters argue that the company’s innovative edge positions it for enduring success, far beyond short-term valuation debates. With the denial now public, attention turns to forthcoming regulatory filings that could provide clearer insights into SpaceX’s strategy and financial health.
The coming weeks promise to reveal more about how SpaceX will transition into a publicly traded powerhouse.

The Tesla and SpaceX merger everyone is talking about is quietly building
Tesla and SpaceX may be closer to merging than Wall Street or either company is admitting.
Elon Musk has reportedly discussed merging Tesla and SpaceX with people close to him, according to CNBC, which cited sources familiar with the conversation. Tesla employees have long expected such a transaction and the topic is openly discussed internally, according to internal sources. With SpaceX is days away from kicking off its Wall Street roadshow for what could be the largest IPO in market history, this would be the first time the company will have public market currency to execute a stock-for-stock deal with Tesla.
The financial logic for a merger would make sense. A combined SpaceX and Tesla would create a conglomerate spanning rockets, satellites, electric vehicles, AI infrastructure, and energy storage valued at roughly $3.35 trillion to $3.6 trillion based on SpaceX’s IPO target range and Tesla’s current market capitalization. The two companies are already more intertwined than most people realize. SpaceX bought $697 million worth of Tesla Megapack systems for xAI data centers and $131 million worth of Cybertrucks. Tesla invested $2 billion in xAI, which subsequently merged with SpaceX. Past transactions also include Tesla selling solar equipment and parts to SpaceX, and SpaceX helping with Cybertruck materials.
Will Tesla join the fold? Predicting a triple merger with SpaceX and xAI
Musk himself signaled where this was heading in November 2025 when he posted on X, “My companies are, surprisingly in some ways, trending towards convergence.” Tesla and SpaceX announced a joint semiconductor fabrication facility in Austin called Terafab on the Gigafactory Texas campus, covering two advanced chip factories, with one serving Tesla’s AI needs for vehicles and Optimus robots, the other targeting space-based data centers under SpaceX’s infrastructure vision.
Wedbush analyst Dan Ives places the probability of a merger at 80% to 90% with a target completion in the first half of 2027. The mechanics of a deal became possible the moment SpaceX filed its S-1. Legal experts said a merger likely would not spark antitrust issues but would raise concerns among shareholders in each company, with questions around which company would be the parent, how a stock swap would take place, and who determines the appropriate price. Musk holds about 20% of Tesla’s equity but controls 85.1% of SpaceX’s voting power through a super-voting share class, meaning he would largely be negotiating the terms with himself.
Not everyone is convinced the timing is imminent. Traders on Kalshi place only 33% odds that a merger will happen before May 2027. The more immediate concern for Tesla shareholders is whether the SpaceX IPO pulls capital and Musk’s attention away from Tesla before any merger consolidates the upside for both.
What is clear is that the structural groundwork is already being laid. The Terafab announcement, the xAI merger, the shared supply chain, the cross-company balance sheet transactions, and now the IPO all point in the same direction. Whether the merger follows in 2027 or later, the two companies are already operating more like divisions of a single entity than independent competitors.
