[Space Exploration Technologies Q3 2026 Earnings Call] SpaceX Revenue Soars 161% to $14.6B as AI Compute Ignites Explosive Growth; Q1 2027 Revenue Guidance Set at $33-37B

SpaceX Q3 2026: Revenue Soars 161% to $14.6B as AI Compute Ignites Growth; Q1 2027 Revenue Guidance Set at $33-37B

Space Exploration Technologies (SpaceX) delivered a blowout third quarter of 2026, with revenue surging 161% year-over-year to $14.6 billion, driven by an inflection in its Super Intelligence (SI) segment and continued momentum in Starlink connectivity. Net income swung to a $4.4 billion profit from a $1.1 billion loss a year earlier, while adjusted EBITDA more than quadrupled to $8.8 billion.

“We are in an inflection moment for SpaceX across launch, connectivity, and super intelligence,” CEO Elon Musk declared at the start of the earnings call, held live from the company’s Starlink factory in Bastrop, Texas.

The results underscore SpaceX’s transformation from a pure-play launch provider into a diversified technology platform spanning space infrastructure, satellite broadband, and AI compute. The SI segment alone generated $7.6 billion in revenue, up $5 billion quarter-over-quarter and $6.7 billion year-over-year, fueled by the ramp of cloud services agreements and the mid-quarter acquisition of Cursor.

Segment Performance

Space: Steady Growth with Favorable Mix

Space segment revenue reached $1.8 billion, up 84% sequentially but only 6% year-over-year, reflecting a favorable customer mix. SpaceX launched 35 rockets in Q3, including 21 Starlink Falcon 9 missions, two Starship flights, one Falcon Heavy, and 12 customer missions. The company secured 18 new national security space launch missions and three additional human spaceflight missions on Dragon.

Connectivity: Starlink Subscribers Hit 13.6 Million

Connectivity revenue rose 69% year-over-year and 22% sequentially to $5.2 billion. Starlink consumer subscribers reached 13.6 million, adding 1.6 million in the quarter. Monthly ARPU increased 5% sequentially to $69. Enterprise and government revenue jumped 91% year-over-year, highlighted by Starshield and aviation contracts now covering roughly 12,000 planes—nearly a quarter of the available aircraft worldwide.

“Starlink is now contracted for roughly 12,000 planes, almost a quarter of the available aircraft,” said CFO Gwynne Shotwell, adding that Lufthansa, Swiss, Copa Airlines, Korean Air, Austrian Airlines, and Asiana Airlines all flew their first Starlink-equipped aircraft during the quarter.

Starlink Mobile surpassed 22 million monthly users, up 37% quarter-over-quarter. The company also received FCC approval to launch 15,000 mobile V2 satellites and announced an agreement to acquire a portfolio of low-band spectrum.

Super Intelligence: The Growth Engine

SI segment revenue of $7.6 billion included $608 million from Cursor, which closed mid-quarter. Excluding Cursor, SI solutions and infrastructure revenue grew 192% sequentially, driven primarily by the activation of new cloud services agreements. SI segment adjusted EBITDA was $5 billion, up $3.8 billion quarter-over-quarter. Operating income was $431 million; excluding $1.2 billion in stock-based compensation from Cursor, operating profit was $1.6 billion.

“We ended the third quarter with 1.7 gigawatts of nameplate compute capacity, with additional data halls already online in early October,” said Brad Garlinghouse, CFO. “We expect to have nearly 2 gigawatts by the end of October and 2.5-3 gigawatts by the end of the fourth quarter.”

The company noted that new compute deployments are generating a payback of less than a year at current pricing, which is tracking slightly above the high end of the $30-$50 per watt range discussed last quarter.

Operational Milestones

SpaceX launched Starship Flight 14 in the final week of the quarter, which reached orbit and deployed operational Starlink V3 satellites—a key milestone. Flight 15, scheduled for November, will attempt to catch both the booster and the ship.

“If we succeed, it will be the first time that an orbital launch vehicle has been fully recovered,” Musk said. “This is a massive technology milestone. The only way that we can extend consciousness beyond Earth on a sustained basis is with a fully reusable orbital launch vehicle.”

Musk also announced the Louisiana Spaceport, targeting first launch in 2028 with high confidence in 2029. The company expects Starship to fly weekly in the first half of 2027 and twice weekly or more by the end of 2027.

Outlook and Guidance

For 2027, Musk expressed high confidence in adding 10 gigawatts of incremental compute, with a stretch goal of over 20 gigawatts. He also projected SpaceX annual recurring revenue of $500 billion to $1 trillion by the end of 2027, contingent on SI compute scaling.

Q&A Highlights

On Terafab and chip fabrication: Musk said internal expectations are for a first test chip to be functional around May or June 2027 at the Austin research fab, with volume production targeted for Q3 2028 at Terafab in Gibbons Creek. “These are very aggressive dates,” he acknowledged, thanking ASML and other suppliers for accelerating equipment deliveries.

On power constraints and funding: Musk revealed that SpaceX is currently turning on 220,000 GB300s per month and has a proprietary plan to reach 20 gigawatts of incremental power and cooling by end-2027. “If you just look at the rate at which we are actually deploying and turning on compute, I’m being as precise as possible about this,” he said. “It is absolutely insane to be deploying, providing the power and all the electrical equipment, the cooling, the batteries, the networking, and everything else that’s needed to turn on 220,000 GB300s a month.” Garlinghouse added that the company has an investment-grade balance sheet and multiple debt capital pools available.

On a potential Tesla merger: Musk addressed the long-rumored combination, stating that both companies have formed special committees of independent directors. “I think some people out there assume that a SpaceX and Tesla merger is a certainty, and I think that would be overstating it,” he said. “Do I think it would be a good idea? Yes. At the end of the day, the shareholders have to be supportive of this.” He noted that any deal would require a 50% vote of all Tesla shares, a high hurdle. No agreement on terms has been reached.

On Starlink Mobile: Shotwell noted that 85-93% of mobile connectivity is via Wi-Fi and that Starlink broadband supports that. She expects S-band spectrum to carry the majority of traffic, with low-band spectrum providing critical building penetration. Musk added that the company sees a clear path to several hundred billion dollars a year in connectivity revenue and will detail the plan in a future presentation.

On compute allocation: Musk said the goal is roughly a 50/50 split between internal and external compute use, with flexibility to shift 60/40 either way. “We could rent out our compute several times over if we said yes to everyone,” he said. “That is why I posted that video meme of the Monty Python Cheese Shop sketch, where the guy goes into a cheese shop to get some cheese, and they actually have no cheese.” He added that short-term contracts are renewing at higher dollars per watt, and that a six-month payback period for compute next year is not impossible.

On V3 satellite capacity: Shotwell said a few hundred V3 satellites are needed for users to really feel the impact, and she expects to achieve that by mid-2027.

On Louisiana Spaceport: Musk said the internal aspiration for first launch from Louisiana is 2028, with 2029 highly likely for at-scale launches. “I’m highly confident,” he said.

Conclusion

SpaceX’s Q3 results reflect a company firing on all cylinders, with the SI segment emerging as its largest and fastest-growing business. The aggressive capital expenditure plans and ambitious revenue targets underscore management’s conviction in the AI compute opportunity. However, the capital-intensive nature of the build-out, potential execution challenges in chip fabrication and power infrastructure, and the high hurdle for a Tesla merger remain key risks. For now, investors are likely to focus on the massive revenue guidance for Q1 2027 and the company’s ability to scale compute capacity at an unprecedented pace.
