Meta’s Q3, Explained: Capex Outran Its Cash by $2.1 Billion

Meta’s third quarter 2026 results, released on 21 October 2026, show revenue of $64.60 billion, up 26% from a year earlier and above the $61-64 billion range Meta gave in July. They also show capital expenditures of $34.91 billion, more than the $32.79 billion of cash its operations generated, which left free cash flow at negative $2.12 billion, according to the release.

The same release raised Meta’s full-year expense outlook to $175-179 billion to include a $9.9 billion legal charge, narrowed its 2026 capex range to $135-145 billion, and announced a new class of non-voting Class C stock that Meta says will give it “the ability to finance its growth.” This piece puts the quarter in one place; our six data pieces published on 21 October cover each line in detail.

The quarter in about a minute and a half, from our published pieces (21 Oct 2026).

The Quarter in One Table

Every figure below comes from Meta’s results release. Percentage changes marked with an asterisk are our arithmetic; the rest are Meta’s.

Two more lines sit on the balance sheet. Cash, cash equivalents and marketable securities were $82.45 billion on 30 September, against $90.26 billion on 30 June in Meta’s second quarter release. Long-term debt was $80.92 billion, against $83.66 billion on 30 June.

What Changed Since the July Guide

In its second quarter release on 29 July, Meta guided third quarter revenue of $61-64 billion. It reported $64.60 billion, $0.60 billion above the top of that range (our arithmetic).

The full-year expense range moved from $165-169 billion to $175-179 billion, which Meta says is “to incorporate the $9.9 billion charge related to legal proceedings recognized in the third quarter.” Taking the charge out of the new range gives about $165.1-169.1 billion, close to the July range (our arithmetic).

The operating income line changed too. In July, Meta wrote: “We continue to expect to deliver operating income this year that is above 2025 operating income.” In October it wrote: “Excluding the third quarter legal charge, we continue to expect 2026 operating income to be above 2025 operating income.”

The capex range went from $130-145 billion to $135-145 billion, a higher floor. Capex in the first nine months was $85.82 billion, so the new range implies $49.18-59.18 billion in the fourth quarter (our arithmetic), against $34.91 billion in the third. Our 19 October preview set out the $79 billion Meta then needed in the second half.

Three lines are new. Meta now expects Reality Labs losses of $18-19 billion in 2026 and “around $15 billion” next year. It says it is “not providing a full-year 2027 revenue outlook.” And it says: “we are still developing our budget and capacity plans for next year, but we expect to continue investing aggressively to support both our core business and emerging AI initiatives.”

Where the Cash Went

Across the six quarterly releases we checked, from the second quarter of 2025 to the third quarter of 2026, this is the first quarter in which capex exceeded cash from operations and free cash flow was negative (our comparison). Capex rose from $17.01 billion in the second quarter of 2025 to $34.91 billion, while cash from operations stayed between about $25.6 billion and $36.2 billion (our arithmetic for the quarters where the release gives only free cash flow and capex).

The cash flow statement also shows no repurchases of Class A stock in the third quarter, against $3.33 billion a year earlier. Dividend and dividend equivalent payments were $1.36 billion. Depreciation and amortization, the cost of earlier spending spread over the years an asset is used, rose to $7.15 billion from $4.96 billion.

What Meta Says the Spending Is Buying

Meta’s outlook commentary makes the case in its own words: “Our AI investments are already delivering substantial incremental advertising revenue through stronger engagement, better recommendations, and more efficient monetization.” In the quarter, ad impressions rose 10% and the average price per ad rose 14%, which our ad pricing piece tracks over six quarters.

On its MSL investments, the release says: “While these investments will take longer to generate returns than those in our core business, the breadth of monetization opportunities and internal efficiencies gives us confidence in their long-term potential.”

Mark Zuckerberg’s quote in the release reads: “We hit major milestones this quarter toward delivering personal superintelligence for everyone – including launching Muse and Muse Wonder, our first frontier model.” He added: “Our investments are paying off, the core business is strong, and we’re seeing velocity across the board.”

How Meta Plans to Pay for It

Meta’s release ties the new Class C stock to funding: “The scale of investment required to compete, sustain growth, expand infrastructure, and pursue new strategic initiatives amidst the AI transformation taking place in the industry is significant.” It says the class “will provide Meta the ability to finance its growth,” with an effective date in January 2027.

Meta lists capital raising, employee compensation and potential acquisitions among the purposes. Our Class C piece covers the Form 8-K terms, including the 20% of Zuckerberg’s new shares that will be freely saleable.

The Costs Outside the Data Centres

The quarter’s biggest one-off cost was legal. Costs include a $9.89 billion charge for Meta’s agreement with 52 attorneys general on teen mental health litigation, which the release says provides for payments of up to about $18.59 billion. Excluding the charge, Meta says income from operations would have been $22.88 billion. Our attorneys general piece and our margin piece cover it; the $25 billion New Mexico penalty ordered the same day is a separate case.

Headcount was 66,775 on 30 September, down 15% from a year earlier, as our headcount piece details. Reality Labs lost $4.13 billion in the quarter, on revenue of $443 million.

How Others Read It

Bloomberg wrote on X that Meta “boosted its capital spending outlook and announced plans to create a new class of nonvoting stock, part of efforts to escalate its already-stratospheric bet on artificial intelligence.” The Financial Times wrote that the new shares would allow Meta “to sell stock to fund its AI spending without diluting Mark Zuckerberg’s control of the company.” CNBC’s headline read: “Meta posts Q3 revenue beat and strong guidance.”

Meta held its analyst call after the release and had not posted the call transcript when this piece was published, so this piece quotes the release only.

The Structural Read

As we read it, the income statement and the cash flow statement tell two stories: revenue rose 26% and the average price per ad 14%, while capex rose about 80% (our arithmetic) and free cash flow turned negative.

As we read it, the guidance wording carries the change: the July expectation of operating income above 2025 now opens with the words “Excluding the third quarter legal charge.”

As we read it, the Class C stock connects the two: the release says the scale of investment required “is significant” and that the new class “will provide Meta the ability to finance its growth.”

Three Implications

FOR META SHAREHOLDERS The fourth quarter capex implied by the new range, $49.18-59.18 billion by our arithmetic, compares with $32.79 billion of operating cash in the third quarter.

FOR META’S FUNDING The release shows cash and marketable securities of $82.45 billion, against $90.26 billion at 30 June, and no Class A buybacks in the quarter.

FOR AI INFRASTRUCTURE SUPPLIERS Meta says it expects “to continue investing aggressively” next year, while it is still developing its budget and capacity plans.

The Business Engineer Lens

This story maps onto the Business Engineer framework The AI Capex Map & The State of AI Hyperscalers.

The framework’s sizing of the cycle: “The total cycle: $725B Big Four + $50B Oracle + $13B Apple + $60B Neoclouds + $80B China + $60B Sovereigns + $48B Other = ~$1.04 trillion in 2026 compute capex.”

As we read it, Meta’s $135-145 billion range is its share of that cycle, and the third quarter shows the cash cost of carrying it: capex above operating cash for the first time in the six quarters we checked. The framework was published in May 2026 and does not discuss these results.

What Is Not Established

Meta does not say how much of its capex goes to AI as opposed to other infrastructure. It gives no 2027 capex figure. It does not say how much Class C stock it will sell, or when. Whether free cash flow stays negative in the fourth quarter is not stated in the release; the guide only bounds full-year capex.

Connecting the Coverage

On 19 October, our preview worked out that Meta needed about $79 billion of capex in the second half to reach its July floor. On 21 October, our results piece reported the negative free cash flow and the Class C plan from the release, and our margin piece covered the drop to a 20% operating margin. Our ad pricing piece covered price per ad rising faster than impressions, and our headcount piece the 15% fall to 66,775. Our attorneys general piece covered the $9.89 billion charge, and our Class C piece the founder terms in the 8-K.

What’s new here: the quarter in one table, and the July-to-October changes in Meta’s own guidance wording side by side.

The Bottom Line

As we read it, Meta’s third quarter is the first in the six we checked where its capex was larger than the cash its business generated. The company says its AI investments are already delivering incremental ad revenue, and its board has approved a new non-voting share class, effective January 2027, to help finance its growth. Its own range implies fourth quarter capex of $49.18-59.18 billion (our arithmetic).
