SpaceX earnings left one big question unanswered

The moment is now for Elon Musk to dial back founder mode at SpaceX ( SPCX ) and dial back up something else he is very good at: charming visionary founder who is asking for large sums of capital from people who want entry to the Muskverse.

Because judging by Musk's commentary on his late Tuesday earnings call, he will need a lot of fresh capital to deliver on aggressive growth timelines for Terrafab, Starlink broadband and rocket reusability. Perhaps way more than most investors think.

"The earnings call served to amplify the enormous calls on capital that loom over the next few years (particularly in the AI segment)," Moffettnathson analyst Julie Zhu said in a note. "SpaceX has moved at a frenetic pace over the last few months, closing the Cursor acquisition; announcing a new Starbase in Louisiana; winning yet another large IaaS contract; launching Starship flight 14; and purchasing Grain's 800 MHz spectrum. Each of these announcements portends an enormous amount of spending, both capex and opex, ahead.

Zhu calls out several specifics on the funding front:

"In the Space segment, Starship continues to require significant R&D. Starbase Louisiana has a reported price tag of $100B+. "

"Within the AI segment, the implied ramp in compute over the coming years will cost hundreds of billions of dollars. Management has also discussed building a foundry for gasturbine blades and vanes in Bastrop to help support power infrastructure. And that is just for training and inference that takes place on the ground; orbital compute at scale will require a separate envelope of expenditure."

"Further, we have yet to mention the R&D that is likely required to push Grok to the frontier."

"A terrestrial buildout for Starlink Mobile's D2D ambitions would require tens of billions, or more, for ground infrastructure and additional spectrum, and still more in start-up costs (think handset subsidies)."

SpaceX gave investors a taste of what could be to come on the debt funding front.

Execs guided to $35 billion to $40 billion in capex for the fourth quarter. This would be a meaningful step-up from $19.6 billion in the third quarter, $18.4 billion in the second quarter and $10.1 billion in the first quarter.

SpaceX ended the quarter with $36.1 billion in debt.

The company's veteran CFO Bret Johnson doesn't seem fazed by the tremors in the debt markets of late on concerns over the financial health of neoclouds such as CoreWeave ( CRWV ) and Nebius ( NBIS ).

All systems go on the pursuit of capital, or so it appears.
