SpaceX Posts 161% Revenue Growth, but a $40 Billion Capex Bill Looms

SpaceX (SPCX) delivered the kind of quarter that makes analysts rewrite their models. Revenue rose 161% to $14.58 billion, profit swung from a loss to $4.4 billion, and the stock jumped about 8% in extended trading on Tuesday.

The shares closed the regular session at $147.79, down 0.1% on the day and down about 2% for October. So the after-hours pop is a rebound from a flat month, not a breakout from a hot streak.

Start with the numbers. According to CNBC's live coverage of the report, adjusted earnings were 45 cents a share against 13 cents expected, and revenue beat the $12.72 billion LSEG consensus by almost $2 billion. Net income was $4.4 billion, compared with a $1.05 billion loss a year earlier.

The biggest surprise is what's driving growth. SpaceX's AI business, which it now calls Super Intelligence, brought in $7.56 billion, up from $813 million a year ago. It's now the company's largest segment, ahead of Starlink.

Starlink is still the profit engine, though. Connectivity revenue rose 69% to about $5.25 billion, subscribers climbed to 13.6 million from 12 million, and the segment's operating income roughly doubled to $2.37 billion. Launch, the business that made SpaceX famous, brought in just $1.77 billion.

Then came the guidance. CFO Bret Johnsen said first-quarter 2027 revenue should land between $33 billion and $37 billion, far above the $22.2 billion analysts had penciled in. He pointed to better visibility into compute contracts over the next six months.

"I think some people out there assume that a SpaceX and Tesla merger is a certainty, and I think that would be overstating it." — Elon Musk, CEO, SpaceX

That quote, relayed by Stocktwits in its post-earnings roundup, matters because Wall Street is already leaning the other way. Gene Munster put the odds of a Tesla combination within two years at 95%, and Dan Ives sees 80%-90% by the end of 2027.

Musk confirmed that both companies have formed special committees of independent directors, and he can't take part because he's a conflicted party. He also noted that Tesla would need approval from 50% of all shares, not just those voting, which he called a high hurdle.

Tesla reports its own quarter after the close today, so the merger conversation is about to get louder. Don't treat it as a done deal. The committees are only exploring a combination, and that vote threshold is real.

Now the part bulls tend to skip: the cost. Capital spending was $19.6 billion in Q3, with more than $16.4 billion going to the AI business. Management guided to $35 billion-$40 billion in Q4.

That spending shows up in the cash balance. GLJ Research's Gordon Johnson flagged that cash fell by about half, from roughly $100 billion to $50 billion, well short of consensus. Both he and Munster expect SpaceX to raise money again, with Munster calling it likely within six months.

There are other loose ends. A federal judge let an NAACP suit over air pollution at SpaceX's Memphis-area data centers move forward, and the Wall Street Journal reported Musk ordered speed limits on Starshield in Ukraine. Neither changes the quarter, but both are headline risk.

The bull case is easy to state. A $63 billion backlog, about $42 billion of it due within a year, plus the Q1 guide, gives investors real numbers behind the ambition.

Even Musk's talk of $500 billion to $1 trillion in annual recurring revenue by the end of 2027 isn't far off ARK's expectations, according to ARK's Brett Winton.

Winton's own model shows $300 billion by then, crossing $500 billion in the first half of 2028.

For anyone watching the stock, three things matter. First, whether the after-hours gain holds at the open. Second, any capital-raise announcement, which could mean dilution or more debt. Third, Tesla's call tonight and any language on a merger timeline.

Bottom line: SpaceX just proved the growth is real, and the next test is whether it can fund a $40 billion quarter without stretching shareholders.
