Tesla (TSLA) stock is in focus on Monday after famed investor Anthony Pompliano publicly urged billionaire Elon Musk to merge the EV maker with SpaceX.
And while the idea of a multi-trillion-dollar AI and aerospace empire sounds like the ultimate sci-fi bull case, such a merger carries massive structural, operational, and financial risks.
At the time of writing, Tesla shares are down more than 6% versus the start of this year (2026).
Why a SpaceX merger isn’t compelling for Tesla stock
Tesla shareholders have spent years waiting for the company to mature into a “profitable” auto and energy business that consistently generates billions in free cash flow.
SpaceX – by contrast – operates on an entirely different scale of capital intensity; building rockets (Starship) and continuous deployment of low-Earth-orbit satellite constellation (Starlink) require a staggering sum of uninterrupted capital.
Merging the entities would mean TSLA’s stable automotive and energy storage margins will act as a piggy bank to fund SpaceX’s long-term, yet-to-be monetized deep-space ambitions.
For fundamental investors, using a successful commercial car and battery business to finance Mars colonization may not be a long-term story they’re eager to underwrite.
A SpaceX merger will significantly dilute TSLA investors
Tesla shareholders also face massive “dilution” if SpaceX uses its enormous market cap to absorb the EV maker.
Here’s the math: you hand over your TSLA shares and receive newly issued SPCS shares in return; while Tesla isn’t printing any new shares, you’re being diluted by a lower-quality corporate margin profile.
You are swapping a name that operates on established, commercial automotive and energy storage cash flows for a tech-heavy mega-conglomerate that posted a $4.28 billion net loss in Q1 primarily due to hardware R&D.
Plus, Wall Street might just slap the combined entity with a heavy conglomerate discount, eroding the ultimate value of your new shares.
Severe governance erosion and reduced voting power
Tesla is a regulated, publicly traded company where institutional investors can exert influence over the board, but SpaceX’s dual-class share structure represents a very different governance model.
Elon Musk holds an estimated 85% of the voting power in SpaceX.
If Tesla is merged or absorbed into a combined entity dominated by SpaceX’s super-voting Class A stock, Tesla investors would see their corporate governance and voting rights effectively neutralized.
Note that several large institutional asset managers (like Vanguard or Blackrock) have strict ESG and corporate governance mandates.
A sudden shift to a structure with zero checks and balances could spark a mass institutional sell-off of TSLA stock.
Geopolitical and regulatory gridlock
Tesla and SpaceX operate in completely different geopolitical spheres, and smashing them together creates a compliance nightmare that could paralyze both businesses.

Crossover exposure would inevitably invite intense scrutiny from the Committee on Foreign Investment in the United States (CFIUS) and Washington defense officials.
If US regulators fear that sensitive aerospace or satellite tech could be compromised due to Tesla’s heavy corporate footprint in China, they could impose crippling operational firewall mandates.
For Tesla shares, this adds further to the broader argument against a SpaceX merger.
