Elon Musk’s next move could be a SpaceX-Tesla merger big enough to challenge Nvidia Corp. for the title of most valuable company on Earth.
Just three sessions into its IPO, SpaceX has already surged nearly 50% to roughly $2.6 trillion, leaving Tesla Inc. and its $1.5 trillion behind.
The wider that gap runs, the cheaper Tesla gets to absorb, and the more control Musk keeps over whatever emerges.
The case for a merger, laid out this week by Bloomberg columnist Liam Denning, is about control as much as size. Any deal would be all-stock, so SpaceX would absorb Tesla by issuing new SpaceX shares to Tesla’s holders.
Don’t Miss:
The more SpaceX is worth relative to Tesla, the fewer shares it has to print to get the deal done.
SpaceX could offer Tesla a one-third premium, valuing it north of $2 trillion, and Musk would still end up with about 74% of the votes.
That premium does three jobs at once. It gives Tesla holders a reason to approve the deal despite the company’s sliding numbers, it locks in Musk’s control, and it triggers the first slice of his $1 trillion Tesla pay package, which converts into yet more SpaceX stock.
Add it up and the combined company lands near a $5 trillion headline valuation, right in Nvidia’s neighborhood.
SpaceX would be paying about 138 times forward EBITDA for a cash-burning carmaker, and its own outside investors would watch their stake shrink from roughly half the company to under a third.
Morningstar pegs SpaceX’s fair value at $780 billion, less than a third of what the stock fetches on a 4% float.

SpaceX has already absorbed xAI at a $250 billion valuation and agreed to buy coding startup Cursor for $60 billion. Folding in Tesla would add real-world robotics data from Full Self-Driving and the Optimus robot, layered on top of Starlink’s orbital footprint.
For Nvidia, the real risk is what these customers are trying to become. Tesla, xAI and SpaceX are among its biggest chip buyers today, but Musk has pitched building his own fab to cut that cord. He calls it Terafab, a roughly $25 billion plant he says would be like TSMC’s gigafab “but way bigger,” producing Tesla’s AI5 chips and custom silicon for orbital satellites.
Polymarket thinks there is a 69% chance NVDA retains its crown as largest company by the end of the year.
Kalshi traders price a SpaceX-Tesla merger before May 2027 around 45% to 55%, up from the mid-20s earlier this year.
SpaceX is a national security asset with classified satellite work, and Tesla carries deep manufacturing and consumer exposure in China. Regulators may balk at parking defense infrastructure and a global automaker under one untrammeled umbrella.

Four leading AI models discuss this article
"A SpaceX-Tesla all-stock merger could unlock transformative scale and AI/space-supply synergies, but only with favorable regulatory clearance, financing, and successful integration; otherwise the hype is unsustainable."
The piece treats a SpaceX-Tesla merger as a near-certain catalyst for a $5 trillion giant, leveraging all-stock math and Musk's control. In reality, the path from private SpaceX to a public, merged behemoth would be blocked by antitrust, national-security reviews, and a capital-intensive integration that could wipe out much of the claimed premium. Even with a big premium to Tesla, the deal would require massive dilution, complex governance to satisfy multiple regulators, and potential divestitures. The article glosses over SpaceX's cash burn, funding structure, cross-border sensitivities, and the risk that customers and suppliers bolt if the combined entity becomes too dominant or unstable.
Regulatory and financing hurdles alone could derail it; antitrust divestitures and governance complexity risk eroding any claimed synergies.
"The regulatory and national security hurdles of combining a defense contractor with a China-exposed automaker make this merger a high-probability non-starter."
The premise of a $5 trillion SpaceX-Tesla merger is a speculative fever dream that ignores the insurmountable regulatory reality. SpaceX is a critical defense contractor reliant on government launch contracts and classified satellite data. Folding a global automaker with massive Chinese manufacturing exposure into a defense entity creates a national security conflict that the Committee on Foreign Investment in the United States (CFIUS) would likely block immediately. Furthermore, the valuation math is absurd; paying 138x forward EBITDA for Tesla’s declining margins while diluting SpaceX’s private investors is a recipe for shareholder litigation, not synergy. This isn't a strategic masterclass; it's a desperate attempt to consolidate power before the underlying fundamentals of both entities face a liquidity reckoning.
If Musk successfully spins the merger as a 'sovereign AI' play, he could leverage the current geopolitical climate to bypass regulatory scrutiny by framing the entity as essential to U.S. technological independence from China.
"A SpaceX-Tesla merger would be a dilution event for SpaceX's public shareholders disguised as a scale story, while the real competitive threat to Nvidia is execution risk on Terafab, not headline market cap."
The article conflates valuation with viability. SpaceX's 50% IPO pop to $2.6T reflects scarcity premium on a 4% float, not fundamental repricing—Morningstar's $780B fair value is a 70% haircut. A Tesla merger at 138x forward EBITDA would be value-destructive for SpaceX's outside investors (diluted from ~50% to <33%), not accretive. The real risk isn't Nvidia losing the 'largest company' crown—it's whether Musk's vertical stack (xAI, Cursor, Terafab) actually reduces chip dependency or becomes a capital-intensive distraction. Regulatory scrutiny on defense + China exposure is mentioned but undersold.
If SpaceX's IPO pop signals genuine AI/satellite infrastructure demand, and Terafab actually executes at TSMC scale, the stack thesis could compress Nvidia's TAM faster than the article implies—making near-term valuation less relevant than optionality.
"Regulatory barriers and extreme valuation gaps make the $5T merged entity unlikely within the article's implied timeframe."
The article overstates merger odds and the resulting $5T valuation. SpaceX trades on a 4% float at $2.6T versus Morningstar's $780B fair value, while Tesla's cash burn and China exposure clash with SpaceX's classified defense work. Regulators are likely to scrutinize any deal that consolidates Starlink, xAI, and Tesla robotics under one controller. Kalshi prices the merger at just 45-55% through May 2027. Even if completed, SpaceX investors would see dilution from issuing shares at 138x forward EBITDA for a non-profitable automaker, and the Terafab remains years away from challenging Nvidia's supply position.
Musk's history of forcing through complex structures suggests he could navigate approvals by spinning off sensitive assets, and the combined data moat in autonomy and satellites might justify premiums markets currently dismiss.
"A staged or partial deal with asset carve-outs could unlock value and reduce immediate dilution."
Grok's dilution worry assumes a single-shot, all-stock merger; that's not the only path. A staged deal with asset carve-outs, earn-outs, or a SpaceX tracking stock could de-risk near-term dilution while preserving optionality on AI, Starlink, and Terafab. Governance and regulatory frictions remain, but dismissing all structural alternatives may be premature. The real risk is multi-jurisdictional approval and the pace of value extraction, not a binary go/no-go.
"Tracking stocks or complex structures will trigger investor litigation and liquidity demands, making a clean merger path nearly impossible."
ChatGPT, your 'tracking stock' suggestion ignores the fundamental issue: institutional investors in SpaceX hold private equity, not public-market liquidity. They aren't looking for complex, synthetic instruments that complicate their exit; they want a clean IPO or a cash-out. A tracking stock would likely trigger massive redemption rights or legal challenges from early-stage investors who signed up for a space-tech pure play, not a convoluted conglomerate. The governance friction is a feature, not a bug.
"IPO-then-merge sidesteps redemption friction, but CFIUS risk on SpaceX's standalone IPO is the real gating item, not merger structure."
Gemini's redemption-rights concern is real, but ChatGPT's staged structure sidesteps it: SpaceX could IPO first (clean exit for early investors), then merge the public entity with Tesla post-listing. That eliminates the tracking-stock friction. The sequencing matters more than the instrument. However, this assumes SpaceX's IPO clears CFIUS scrutiny—which Gemini flagged but nobody quantified. What's the probability CFIUS blocks or conditions a SpaceX IPO on Starlink divestiture before any Tesla merger is even on the table?
"IPO sequencing would force Starlink divestiture under CFIUS, destroying the synergies priced into the merger."
Claude, an IPO-first sequence actually heightens CFIUS exposure rather than reducing it. Once SpaceX lists, Starlink's classified payloads and Tesla's Shanghai supply chain trigger fresh outbound-investment reviews that private structures currently avoid. Any mandated divestiture would erase the vertical data loop between satellites, autonomy, and robotics that supposedly justifies the premium, leaving public shareholders with two disconnected, capital-intensive businesses.
The panel consensus is that a SpaceX-Tesla merger is highly unlikely due to insurmountable regulatory hurdles, significant dilution, and potential national security conflicts. The path to a $5 trillion valuation is blocked by antitrust reviews, capital-intensive integration, and the risk of customer and supplier loss.
No significant opportunities were identified by the panel.
Regulatory scrutiny, particularly from CFIUS, is the single biggest risk flagged by the panel, which could block the merger or require divestitures that undermine the strategic rationale of the deal.
