The bullish merger narrative assumes Tesla shareholders get a substantial premium.
I want to challenge the incentive behind that assumption.
What if Musk benefits more from a higher SpaceX-to-Tesla valuation ratio than from a higher Tesla acquisition price?
That makes today’s earnings important: Tesla could strengthen its case for a premium—or reinforce the perception that it is the weaker partner.
MUSK OWNS BOTH SIDES. HE DOES NOT OWN THEM EQUALLY.
Using the ownership figures in my analysis, Musk has substantially greater economic exposure to SpaceX than Tesla.
In an all-stock merger, paying more for Tesla means giving Tesla holders a larger percentage of the combined company. That dilutes existing SpaceX holders—including Musk.
Paying less for Tesla does the opposite.
That does not establish that Musk intends to push Tesla’s stock down. But it challenges the assumption that maximizing Tesla’s deal price necessarily maximizes his own interests.
THE COUNTERARGUMENT: A HIGHER TESLA VALUATION UNLOCKS HIS COMPENSATION
A qualifying Tesla change of control at sufficiently high valuations could unlock compensation tranches without the normal operational milestones.
So yes, crossing thresholds such as $2T or $2.5T could give Musk additional Tesla shares.
But the relevant question is:
Are those additional shares worth more to him than the ownership he gives up through a more generous Tesla exchange ratio?
In my simplified $2.2T SpaceX / $2T Tesla example, the first approximately 35.3M-share tranche adds only around 0.4 percentage point to his combined economic ownership.
That first tranche does not automatically outweigh the effect of giving all Tesla shareholders a larger slice. Higher thresholds would need their own calculations.
WHAT IF SPACEX DOESN’T KEEP RALLYING?
Suppose SpaceX stays near $2.2T over the next few months.
Using simplified merger math:
\ Tesla valued at $2T: SpaceX holders own 52.4% of the combined company; Tesla holders own 47.6%.
\ Tesla valued at $1.5T: SpaceX holders own 59.5%; Tesla holders own 40.5%.
\*Tesla valued at $1T: SpaceX holders own 68.8%; Tesla holders own 31.2%.
These are illustrative negotiated deal valuations, not automatic outcomes from stock-price moves.
But the incentive is clear: SpaceX does not have to rise for the relative valuation to move in its shareholders’ favor. Tesla could fall.
From a $1.53T starting point, a 20–30% decline would put Tesla around $1.22T–$1.07T.
If that lower valuation carried into the deal terms, SpaceX holders would surrender substantially less ownership to acquire Tesla.
That could make the economics more attractive to the SpaceX side. It would not guarantee that Tesla’s independent committee or shareholders accept them.
CONTROL IS ANOTHER PART OF THE PRIZE
If SpaceX’s super-voting structure survives, Musk could preserve voting control while owning well below half the combined economic equity.
A lower Tesla valuation would primarily protect his economic ownership. The share classes and governance terms would determine his voting control.
Together, those terms could give him substantial control over Tesla within a combined company—without needing to maximize Tesla’s standalone valuation first.
WHY TODAY’S EARNINGS MATTER
Strong margins, cash generation, and credible operating progress would strengthen Tesla shareholders’ argument for a premium.
Weak results and another call dominated by distant promises could strengthen the opposite narrative: SpaceX is the more attractive business, while Tesla’s valuation is harder to defend.
My bearish scenario does not require Musk to deliberately tank the stock. Disappointing results and limited reassurance could be enough.
MY THESIS
Musk has competing incentives, and the compensation award does not automatically make him a champion of the highest possible Tesla acquisition price.
