SpaceX (SPCX) Q3 Earnings Review: AI Takes the Lead

Before earnings, I said SpaceX was becoming an AI infrastructure company. On Tuesday, AI passed Starlink—and the AI segment turned profitable!

SpaceX (SPCX) reported Q3 2026 results after the close on Tuesday, October 20. The quarter was great, but the forward guidance is what has me most excited. Here’s my post-earnings take, my $160 momentum signal, and what I’m watching as lockup shares become eligible for sale.

The quarter in 60 seconds

• Revenue: $14.58 billion, up 161% year over year, versus roughly $12.9 billion expected.
• Diluted EPS: $0.35.
• First quarterly profit since going public: $4.4 billion in net income.
• AI (“Super Intelligence”) revenue: $7.56 billion, now more than half of total sales.
• Starlink / Connectivity revenue: $5.25 billion.
• Nameplate compute: 1.7 GW, up from 1.4 GW last quarter.

Earnings were fire. 🚀🔥

AI is now SpaceX’s biggest business by revenue

AI passed Starlink. This is an AI infrastructure company that also launches rockets.

• AI revenue of $7.56 billion was up 830% year over year and 195% from last quarter’s $2.56 billion.
• That is bigger than Connectivity’s $5.25 billion and represents approximately 52% of total company revenue.
• The AI segment flipped to a $431 million operating profit, from a $1.26 billion operating loss in Q2.

That’s a neocloud, and now it’s a profitable one at the segment operating-income level. Almost nobody is calling SpaceX a neocloud yet. They will. My view: the market priced today’s AI business, not tomorrow’s.

There’s an important distinction: AI is now the largest segment by revenue. Connectivity still produced more operating income—about $2.37 billion versus AI’s $431 million. The growth story and the current profit engine are different parts of the same company.

The guidance is the real story

Two numbers from the call stand out, and they refer to different quarters:

• Q1 2027 revenue guidance: $33–37 billion. That is more than double Q3’s $14.58 billion. Management tied the outlook to greater visibility into its compute contract pipeline.
• Q4 2026 capital-spending guidance: $35–40 billion. That is roughly double Q3’s $19.59 billion.

Source: management’s earnings-call remarks. These are forward-looking expectations, not reported results.

Last quarter, SpaceX beat and the stock sold off sharply on spending worries. This time, management raised spending expectations and the stock traded higher in the reaction captured in my Wednesday notes. That’s a different response from the market.

For me, the question is whether the additional spending converts into the revenue growth management is describing. The size of the opportunity is exciting; execution still matters.

My post-earnings momentum signal

My Tuesday setup used an expected move of about $10.30 from the $147.79 October 20 close. This is the reference in my earnings notes, separate from the earlier October 19 snapshot in my preview.

Here’s my framework:

• A gap of 1.5× to 2× that expected move—approximately $163.25–$168.40—puts the stock in my post-earnings momentum zone.
• A break through $160 is my short-term momentum buy signal for a potential post-earnings rally.

What happened Wednesday morning?

Market snapshot: October 21, 2026, through 11:36 a.m. Pacific. These are the Yahoo Finance observations recorded in my research notes, not live prices or final session statistics.

• Open, 6:30 a.m.: $160.56. A gap of $12.77, or approximately 8.6%—about 1.2× the expected move.
• High, 7:03 a.m.: $166.18. Up $18.39, or approximately 12.4%, inside my 1.5×–2× zone.
• Low through the snapshot, 11:12 a.m.: $156.93.
• At 11:36 a.m.: $158.61. Up $10.82, or approximately 7.3%, on about 178 million shares. That was roughly twice the approximately 91-million-share 10-day average recorded heading into the week; the session was still in progress.

Market-data reference: Yahoo Finance’s SPCX page.

It broke through $160 at the open and tagged the momentum zone shortly afterward, then pulled back under $160. The opening gap was about 1.2× the expected move, not the full 1.5×. Reaching that zone later in the session is different from opening there.

For the short-term signal to confirm, I want to see SPCX reclaim $160 and hold it, ideally pushing back toward the morning high of $166.18.

It depends on the time frame, though. For my long-term growth thesis, the report and the numbers themselves are a buy signal, and I’m buying more at the prices discussed in these notes. That is my own investment decision; the short-term trading setup still needs confirmation.

Three volatility events this week

SPCX has three distinct events to work through:

1. Earnings on Tuesday, October 20: A strong report, the first quarterly profit since the IPO, and AI becoming the largest revenue segment.
2. The reaction on Wednesday, October 21: An open above $160, a high inside my momentum zone, and a pullback in the morning snapshot.
3. The lockup releases: Up to approximately 1.3 billion shares on Thursday, October 22, followed by approximately 328 million shares on October 24. October 24 is a Saturday; the next regular trading session is Monday, October 26.

Those are maximum shares becoming eligible for sale, not confirmed sell orders. Lockup supply can pressure the stock even after a great report. This is a long-term game, with volatility in between!

What I’m watching next

• $160: Reclaim and hold would put my post-earnings momentum signal back in focus.
• The approximately $163.25–$168.40 zone: The $166.18 high in my morning snapshot is the first level I want to see challenged again.
• Lockup selling: How much supply actually reaches the market, and whether buyers absorb it.
• The Q1 2027 revenue guide: Whether execution supports the $33–37 billion outlook and how analysts adjust their forecasts.
• Compute growth: 1.7 GW at September 30, and how quickly additional capacity becomes productive.

One more thing: SpaceX shares for kids

One more thing I’m excited about: Elon Musk has pledged to give one of his SpaceX shares to every child in America next year. Brad Gerstner has discussed the pledge in connection with Trump Accounts. Reporting on Musk’s pledge, Gerstner’s comments.

I’ve set up Trump Accounts for my kids, and I think everyone should know about them. It’s unfortunate that some people don’t want to take advantage of them just because they’re called “Trump Accounts.”

The SpaceX giveaway is a pledge, and eligibility, distribution details, and implementation still need to be confirmed. For the account program itself, start with the IRS’s official Trump Accounts information.
