• Meta's AI agent, Muse, is unprofitable due to "very high compute costs," CEO Mark Zuckerberg says.
• Meanwhile, Meta expects Reality Labs, its AI glasses division, to lose $15 billion next year.
• The social media giant has a plan to fix that.

Meta says some of its biggest cash incinerators could finally start turning profits.

The social media giant, which generated over 97% of its quarterly revenue from ads, has faced persistent questions from investors about the lack of profitability in its AI and hardware initiatives.

Meta CEO Mark Zuckerberg addressed those concerns head-on during its third-quarter earnings call on Wednesday.

Zuckerberg said that Muse, the AI assistant it launched last month, is unprofitable since it's "very compute intensive to run." Meta expects to start turning that around next year by massively improving Muse's efficiency.

"If compute efficiency continues improving quickly for another few years, which we think is highly likely, then Muse will be highly profitable over multiple years," he said.

Meta plans to make money from Muse by taking a small transaction fee off of purchases it drives, Zuckerberg said at Meta's Connect conference last month.

Zuckerberg added that Muse, which launched only in the US and Canada, wasn't launched globally due in part to the amount of compute it requires. (Meta's North American users are generally its most lucrative.)

Zuckerberg also struck a positive note about its cash-hemorrhaging Reality Labs division, which makes products like Meta Ray-Bans and virtual reality glasses.

Meta expects Reality Labs to narrow its losses to about $15 billion in 2027, down from the $18 to $19 billion it expects to lose this year. The division should start trending toward profitability next year, as Meta's AI systems make it more useful, Zuckerberg said.

"I continue to believe that the path to delivering holographic experience, of bringing together the physical and digital worlds and everyday glasses, will come through VR first," Zuckerberg said.

• SpaceX's earnings reveal growing capex as well as AI revenue that surpassed its Starlink business for the first time.
• The company reported overall capex spending in line with estimates. It projected it could double in the current quarter.
• AI-related spending was slightly less than expected but still more than previous quarters.

SpaceX's second-ever earnings report revealed it's spending more than ever on AI — and that could soon double.

SpaceX reported spending $16.4 billion on AI-related capex in the third quarter, continuing the acceleration of AI spending seen in recent quarters.

SpaceX spent roughly $19.6 billion on overall capital expenditures in the third quarter as Grok maker continues its AI buildout. That was squarely in line with what Wall Street analysts were expecting.

Of that $19.6 billion, SpaceX reported spending $16.4 billion on AI-related capex. Analysts were expecting $16.9 billion.

SpaceX expects capex to balloon in the current quarter, with CFO Bret Johnsen forecasting $35-$40 billion due to new compute coming online. Johnsen also said SpaceX expects to quickly see returns on its investments.

"At current pricing, new compute deployments are generating a payback of less than a year," he said.

SpaceX's stock was trading up 4% after hours following the results. The company is broadcasting the earnings call on X, becoming one of a small list of companies to broadcast video of the gathering.

During the earnings call, SpaceX CEO Elon Musk said that chips are no longer the biggest constraint to AI buildout.

"So talking about SpaceX superintelligence, SpaceXSI — "sexy," whatever — so as I think people are starting to realize the constraints on deployment of superintelligence is more in power and cooling and infrastructure than it is in chips," he said.

SpaceX's AI revenue grew significantly quarter-over-quarter to $7.6 billion — ahead of analysts' estimates of $6.3 billion. This report also marks the first quarter since SpaceX purchased Cursor.

That revenue means that SpaceX's AI segment officially brought in more revenue than its Starlink business. Starlink brought in $5.2 billion for the quarter.

SpaceXAI has since rebranded as SpaceXSI, following Musk's alignment with President Donald Trump's preferred rebranding of "artificial intelligence" to "super intelligence."

One area where SpaceXSI has found some success is leasing its compute to Anthropic, Google, and Reflection AI. During the company's last earnings call, SpaceX CFO Bret Johnsen said the leasing arrangements had generated $1.6 billion in additional revenue.

Musk said that SpaceX is being inundated with lease requests.

"We are also frankly hounded relentlessly by every hyperscaler and by dozens of smaller companies to rent more of our compute," he said. "So we could rent out our compute several times over if we said yes to everyone."

Overall, he said the allocation for SpaceX compute is something "that's going to change from one month to the next."

"I guess as a rough approximation, our goal is to kind of split it 50/50 more or less, where half of the compute is used internally, and half of it is rented to others," he said. "But that number could shift 60/40 one way or the other."

Correction: Tuesday, October 20, 2026 — An earlier version of this story incorrectly included two values for SpaceX's overall capex. The correct value is $19.6 billion.
