Elon Musk said on Tuesday that combining Tesla and SpaceX would be “a good idea,” confirming that both companies have formed special committees to study a potential merger. The disclosure, which Reuters distributed in its Morning Bid column early Wednesday, sent shares in Starlink’s parent company up roughly 8% in extended trading and reignited a debate that has simmered for years: should the world’s most valuable car maker and the world’s dominant rocket and satellite operator become one company.
Nothing is signed. No structure has been agreed. But the tesla spacex merger conversation has moved from an off-hand remark at an investor conference to a formal process involving independent directors, and the hardware case behind it is just as interesting as the financial one. Musk has pointed to overlapping work on chips, robotics, and orbital infrastructure as reasons the two companies might be worth more together than apart — a pitch that, if realized, would hand Tesla something close to literal rocket boosters rather than just the metaphorical kind implied by Reuters’ headline.

What Reuters’ Morning Bid Column Actually Reported
The Reuters Morning Bid dispatch, written by Gregor Stuart Hunter and edited by Muralikumar Anantharaman, was published October 21, 2026, at 12:37 a.m. It named three companies at the center of the story: Tesla, SpaceX, and Starlink. The column’s framing was blunt: after years of speculation, Tesla “may get rocket boosters for real this time,” a nod to both the literal cold-gas thruster hardware already fitted to the Tesla Roadster and the broader idea that a SpaceX tie-up could accelerate Tesla’s technology roadmap.
According to the Reuters wire carried by TradingView, the column also cited a Wall Street Journal report claiming Musk had ordered a slowdown of a military-grade version of Starlink used by Ukraine, attributing that account to U.S. officials and people familiar with the matter. Reuters was explicit that it could not independently verify the Journal’s reporting on the Starlink slowdown. That caveat matters: it means the Ukraine angle, while part of the same news cycle, stands on a different evidentiary footing than the merger-committee disclosure itself, which came directly from Musk on a SpaceX earnings call.
Musk Says a Tesla-SpaceX Merger Would Be “A Good Idea”
Musk’s own words carry most of the weight in this story, and he has been consistent for months about where he stands. On a SpaceX earnings call, Musk said: “I think it would be a good idea, but it’s really up to the special committees of both companies.” That single line is the closest thing to an official position Musk has taken, and it came paired with an acknowledgment that he is personally conflicted and cannot sit in on the committee discussions given his role atop both companies.
Musk has telegraphed this view before. Months earlier, discussing why the two companies remained legally separate, he said: “As you can tell from the many collaborations on so many fronts with SpaceX, there’s more and more overlap,” before adding that “we can’t talk about, you know, combining companies and that kind of thing on an earnings call” because any combination would need to follow a formal corporate process. At an industry conference, he went further, musing: “With all this collaboration, on so many levels, who can imagine what action one might take when there’s so much close collaboration in so many areas.” Taken together, the remarks read less like a sudden pivot and more like a position Musk has been building toward in public for the better part of a year.
Inside the Special Committees Weighing a Deal
The mechanics matter here. Tesla and SpaceX have each formed independent committees made up of directors who are not Musk, tasked with evaluating whether a combination makes sense and, if so, on what terms. Musk has said the committees were formed at shareholders’ request rather than announced as a done deal, and he has repeatedly cautioned investors against treating a merger as certain. No transaction terms had been agreed as of the disclosure, and one report suggested SpaceX could end up acquiring Tesla rather than the reverse, though no structure has been finalized publicly.
That process-first framing is important for anyone trying to read the stock reaction. Markets are not pricing in a finished transaction; they are pricing in the probability that two of the most valuable private-and-public hybrid technology franchises on the planet end up under one roof, with all the hardware, supply chain, and balance-sheet implications that would carry. For a deeper look at how this specific disclosure moved markets, see our earlier coverage of the 8% stock jump and the 50% shareholder hurdle Tesla would need to clear.
The Hardware Case: Chips, Robotics, and the Terafab Connection
What separates this merger talk from a routine corporate-finance story is the hardware argument Musk has made for it. In his most expansive comments on the subject, Musk said: “I do think there’s a lot of merit to combining the companies as we are pretty much in the superintelligence singularity, and there’s a lot to be gained from cooperating on developing superintelligence software, chip design, the Terafab obviously, robotics, mass-to-orbit with the Starmind constellation, connectivity.” That is a hardware roadmap as much as a financial one: chip design, a dedicated chip-manufacturing project referred to as Terafab, humanoid robotics, and orbital infrastructure all show up in the same sentence.
Tech-insider.org has tracked the Terafab project closely, including reporting on its target timeline for chip production beginning around the third quarter of 2028. If Tesla and SpaceX were to formally combine, a jointly owned chip plant designed to serve both companies’ AI and compute needs would stop being an awkward cross-company arrangement and start being a straightforward internal investment, at least on paper. That is the crux of the hardware argument: shared chip design, shared manufacturing capacity, and shared robotics development are easier to justify and fund when they sit inside one balance sheet rather than two.
From Roadster Thrusters to Rocket Boosters: The Literal Hardware Link
The “rocket boosters” framing in the Reuters headline is not purely metaphorical. Tesla has already fitted cold-gas thruster hardware, sourced from SpaceX engineering know-how, to the Roadster’s flight-trim variant, as tech-insider.org detailed in its report on the SpaceX hardware behind the Roadster’s test flights at McGregor. That existing arrangement, where SpaceX propulsion engineering already informs a Tesla product, is the clearest real-world evidence that hardware collaboration between the two companies is not hypothetical.
A formal merger would not, on its own, make Tesla a rocket company. Nothing in the confirmed record states that Tesla vehicles would gain SpaceX rocket-booster technology as a direct consequence of combining the two businesses, and that claim should be treated as unconfirmed speculation rather than fact. What a merger would plausibly do is remove the legal and contractual friction that currently governs how SpaceX hardware, engineering talent, and manufacturing capacity get shared with Tesla, replacing arm’s-length agreements with internal resource allocation.
A $3.5 Trillion Giant? Sizing Up the Potential Combined Company
Reuters’ Morning Bid column put a number on the hypothetical: a combined Tesla-SpaceX entity would be worth about $3.5 trillion, which the column estimated would rank it fifth among the world’s most valuable companies, slotting in between Microsoft and Amazon. That estimate comes with the same caveat as everything else in this story — it is a projection tied to an unfinished process, not a confirmed valuation of an existing entity, since no merger has happened and no combined company currently exists to be valued.
Still, the scale of the number is itself the story. Tech-insider.org previously reported on how Musk walked back his own $28.5 trillion total-addressable-market estimate for SpaceX, a reminder that figures tied to Musk’s companies tend to run large and sometimes get revised. For context on how that earlier estimate held up, read our coverage of Musk’s admission that the $28.5 trillion TAM estimate was wrong. The $3.5 trillion merger estimate deserves the same scrutiny as it moves from a column inch in a newsletter to a figure that gets repeated across financial media.
Where a Combined Giant Would Rank, According to the Estimate
| Estimated Global Rank | Company | Status |
|---|---|---|
| 4th | Microsoft | Existing public company, cited by Reuters’ Morning Bid as positioned just ahead of the estimated combined entity |
| 5th | Tesla + SpaceX (hypothetical) | Approximately $3.5 trillion, per the Reuters Morning Bid estimate; no merger has been finalized |
| 6th | Amazon | Existing public company, cited by Reuters’ Morning Bid as positioned just behind the estimated combined entity |
Treat this table as a snapshot of one news outlet’s estimate, not a verified ranking of actual market capitalizations. The underlying math behind how Reuters arrived at $3.5 trillion was not published in detail in the available reporting, and tech-insider.org is not able to independently confirm the precise valuation methodology used.
Tesla’s 50% Shareholder Hurdle, Explained
Even if the special committees agree on terms, Musk flagged a structural obstacle that makes a Tesla-SpaceX merger far from a rubber-stamp exercise. Tesla’s shareholder approval threshold for a transaction of this magnitude would require a vote representing 50% of all outstanding shares, not simply 50% of the shares that actually get voted. Musk himself described that requirement as a high hurdle, and the distinction is significant: many public companies only need a majority of votes actually cast, which is a much lower bar to clear than a majority of every share in existence, including shares held by passive index funds and retail investors who may never submit a ballot.
That threshold effectively means Tesla’s committee and board would need an unusually broad mobilization of shareholder turnout to get a deal approved, something past Tesla shareholder votes on Musk’s compensation and board matters have shown is achievable but not guaranteed. Our earlier report on the 50% hurdle tied to the merger-committee disclosure goes into more detail on how that voting mechanic could shape the timeline.
SpaceX Shares Jump 8% as Investors React
Markets moved fast. Shares tied to Starlink’s parent company rose approximately 8% in extended trading immediately after Musk’s merger-committee comments became public, according to the October 21 coverage distributed via Reuters. That kind of single-session jump reflects investors pricing in the possibility that SpaceX, and by extension its Starlink satellite business, could eventually trade on terms closer to Tesla’s publicly listed equity, or that a combined entity would unlock value neither company can access while operating independently, with SpaceX still privately held.
Coverage of Tesla’s own stock reaction has been tracked separately on the Investing.com Tesla stock news feed, which has logged a steady run of merger-adjacent headlines across October as the special committees took shape. The gap between how SpaceX-linked shares moved and how Tesla’s own stock moved is itself a data point worth watching as the committees progress, since it suggests investors see more immediate upside for SpaceX’s side of a potential deal than for Tesla’s.
The Starlink Ukraine Report Adds a Complication
The same Reuters column that broke the merger-committee news also referenced a separate and more fraught story: a Wall Street Journal report alleging Musk ordered a slowdown of a military-grade version of Starlink used by Ukraine, citing U.S. officials and people familiar with the matter. Reuters was careful to note it could not independently verify that reporting. It remains unconfirmed whether Musk personally ordered the slowdown described in the Journal’s account, and readers should treat that detail as a contested claim rather than an established fact.
Tech-insider.org has covered the broader pattern of Starlink capacity constraints affecting Ukrainian military users in earlier reporting, including analysis of how a 100 mph speed cap on Starlink terminals has affected Ukrainian drone missions. The timing of the Journal’s report landing in the same news cycle as the merger disclosure means the two stories are now linked in public discussion, even though they describe different companies, different decisions, and different levels of verification.
Historical Context: A Decade of Merger Speculation
Speculation about combining Tesla and SpaceX is not new. Musk has run both companies simultaneously for more than fifteen years, and investors have periodically floated the idea of a formal combination, particularly as SpaceX’s valuation climbed in private funding rounds and Starlink grew into a business with its own standalone commercial logic. What changed this week is procedural, not emotional: for the first time, both boards have put the question into a formal structure, independent committees, rather than leaving it as a recurring talking point on earnings calls.
Tech-insider.org tracked the earlier phase of this story when Musk backed the idea following SpaceX’s first reported quarterly profit, a milestone that gave the merger conversation renewed financial grounding. That earlier piece, on Musk backing a Tesla-SpaceX merger as SpaceX posted a $4.4 billion profit, is worth revisiting now that the talks have advanced from a supportive comment to an actual committee process.
Overlap Areas Musk Has Cited as the Hardware Rationale
| Area Musk Cited | What It Involves | Current Status |
|---|---|---|
| Software / “superintelligence” | Shared AI model development across Tesla’s vehicle and robotics software and SpaceX’s operational systems | Described by Musk as an area of growing overlap; no joint software entity has been announced |
| Chip design | Custom silicon for AI training and inference used by both companies | Cited by Musk as a cooperation area; specifics of any shared chip architecture have not been disclosed |
| Terafab | Joint chip-manufacturing project referenced by Musk | Previously reported target of chip production beginning around Q3 2028 |
| Robotics | Humanoid and industrial robotics development | Cited by Musk as a shared area of investment; no combined robotics unit exists today |
| Mass-to-orbit / Starmind constellation | Satellite infrastructure referenced alongside connectivity goals | Named by Musk as part of the cooperation case; detailed specifications were not provided |
| Connectivity | Broader satellite and terrestrial connectivity services | Cited generally by Musk; no new product or service has been confirmed as a direct result |
Every row in that table traces back to a single list Musk gave in his own words, and none of it amounts to a confirmed integration plan. It is best read as a roadmap of talking points rather than a disclosed engineering schedule.
Regulatory and Antitrust Risks Ahead
Reuters’ own coverage flagged that a merger of this size would face substantial regulatory risk, and that assessment lines up with how analysts generally think about combinations between two companies with this much combined market influence across automotive, energy, aerospace, defense-adjacent satellite communications, and now AI infrastructure. A deal spanning that many sectors would likely draw attention from antitrust regulators and, given SpaceX’s government contracts, from national security reviewers as well.
None of the available reporting specifies which regulatory bodies would have jurisdiction or what a formal review timeline might look like, and tech-insider.org is not treating any specific agency involvement as confirmed at this stage. What is confirmed is that Reuters itself, in reporting the story, explicitly characterized regulatory risk as substantial, which is a meaningful signal from a wire service that does not typically editorialize on deals that haven’t been formally announced.
Competitive Landscape: How Rivals Are Positioned
A combined Tesla-SpaceX would not operate in a vacuum. On the automotive and energy side, Tesla already competes with companies building their own in-house AI and chip capabilities rather than relying on third-party silicon. On the aerospace and satellite side, SpaceX’s Starlink competes with rival satellite constellations that have been expanding gateway and spectrum access in markets Starlink has struggled to enter quickly. A deal that pools Tesla’s manufacturing scale with SpaceX’s launch cadence and orbital infrastructure would, in theory, give the combined entity leverage that neither rival automakers nor rival satellite operators can easily replicate on their own, since few competitors control both a high-volume vehicle manufacturing base and an orbital launch and satellite network simultaneously.
That theoretical advantage is precisely what makes the hardware argument compelling to some investors and alarming to regulators at the same time. Vertical integration across manufacturing, chips, robotics, and orbital infrastructure is the kind of combination that is genuinely difficult to find anywhere else in the public markets, which is part of why the 8% stock pop happened as quickly as it did.
Market Reaction Beyond the Headline Number
Broader financial media moved quickly to contextualize the news within the day’s wider market mood. Coverage tracked by MarketScreener’s roundup of global equity moves showed the merger-committee disclosure landing amid a broader session of mixed trading across Asian and European markets, a reminder that the Tesla-SpaceX story, however large, is still just one data point in a busy global trading day. Business desks across multiple outlets, including a general markets brief carried by the Herald Sun’s business section, picked up the Reuters wire within hours, a sign of how quickly a single earnings-call comment from Musk can propagate across financial media.
For comparison purposes, market commentary referencing Microsoft’s own financial disclosures, tracked through feeds like the one aggregated by Schwab’s market news wire, gives some sense of the scale Reuters was gesturing at when it placed a hypothetical combined Tesla-SpaceX between Microsoft and Amazon in its ranking estimate.
What Happens Next: Timeline to Watch
There is no public timeline yet for when the special committees will report back, and Musk himself declined to speculate on how long the process might take. What is known is that the committees exist, that they are made up of directors independent of Musk, and that any resulting proposal would still need to clear Tesla’s unusually demanding 50%-of-all-shares voting threshold before it could close. That combination of an open-ended committee review and a high shareholder bar suggests this is a story measured in months rather than days.
Investors watching for the next concrete milestone should expect updates to surface around Tesla’s and SpaceX’s next scheduled earnings calls, since that is the venue Musk has used for his most substantive comments on the topic so far, rather than through standalone press releases.
Five Predictions for the Tesla-SpaceX Merger Story
- The special committees will likely take several months to reach a recommendation, given the scale of the businesses involved and the lack of any disclosed deadline.
- Expect additional detail on the Terafab chip project to surface before a formal merger proposal does, since shared chip manufacturing is the most concrete hardware argument Musk has made publicly.
- Regulatory scrutiny, flagged explicitly by Reuters as substantial, will probably become the dominant storyline once and if a specific deal structure is proposed, overtaking the current focus on valuation estimates.
- The Wall Street Journal’s Starlink-Ukraine report will likely draw continued attention independent of the merger talks, given its sensitivity for U.S. and allied government relationships.
- Tesla’s 50%-of-all-shares voting hurdle will shape deal timing more than almost any other single factor, since mobilizing that level of shareholder turnout historically takes longer than a simple majority-of-votes-cast threshold.
Frequently Asked Questions
Has the Tesla-SpaceX merger actually been approved?
No. As of October 21, 2026, Tesla and SpaceX have only formed special committees of independent directors to study a potential merger. No transaction terms have been agreed, and Musk has explicitly cautioned that a deal is not certain.
Why did SpaceX-linked shares jump 8%?
Shares rose approximately 8% in extended trading immediately after Musk disclosed the special committees on a SpaceX earnings call, reflecting investor interest in a potential combination rather than any confirmed transaction.
What is the Terafab project mentioned alongside the merger talks?
Terafab is a chip-manufacturing project Musk cited as one of the hardware areas where Tesla and SpaceX already cooperate. Tech-insider.org has previously reported that the project is targeting chip production around the third quarter of 2028.
Will Tesla vehicles get actual rocket booster hardware from this deal?
That is not confirmed. Tesla’s Roadster already uses cold-gas thruster hardware developed with SpaceX engineering input, but there is no confirmed plan stating that a merger would add new rocket-booster technology to Tesla’s vehicle lineup. Treat that framing as a headline metaphor rather than a disclosed product plan.
What is Tesla’s shareholder voting hurdle for a merger?
Musk said Tesla’s approval threshold requires a vote representing 50% of all outstanding shares, not just 50% of the shares actually voted. He described that as a high hurdle compared with a typical majority-of-votes-cast standard.
Is the Starlink-Ukraine slowdown report confirmed?
No. The Wall Street Journal reported that Musk ordered a slowdown of a military-grade Starlink service used by Ukraine, citing U.S. officials and people familiar with the matter. Reuters explicitly said it could not independently verify that report, so it remains an unconfirmed claim.
How big would a combined Tesla-SpaceX company be?
Reuters’ Morning Bid column estimated a combined entity could be worth about $3.5 trillion, ranking fifth globally between Microsoft and Amazon. That figure is an estimate tied to an unfinished process, not a confirmed valuation of an existing combined company.
When will we know if the merger is actually happening?
No public deadline has been disclosed. The special committees are independent of Musk and have not announced a timeline, and any proposal would still need to clear Tesla’s 50%-of-all-shares voting requirement before closing.
