Meta reported third-quarter 2026 revenue of $64.6 billion on October 21, up 26% from $51.2 billion a year earlier, one of its strongest growth quarters in years. A single $9.89 billion legal charge then cut net income to $9.86 billion and diluted earnings to $3.83 a share, and capital spending of $34.9 billion ran ahead of the cash the business produced. The quarter is a clean read on the trade Meta is making: a powerful advertising engine paying for an expensive bet on artificial intelligence.

The headline numbers

Revenue of $64,601 million grew 26% year over year, and almost all of it came from advertising across Facebook, Instagram, WhatsApp and Messenger. Family of apps advertising revenue was about $63.1 billion.

Income from operations was $12,988 million, down 37% from a year earlier, and the operating margin narrowed to 20% from 40%. That decline was not an operating weakness; it was the legal charge, which landed entirely in this quarter.

Diluted earnings per share were $3.83, compared with $1.05 a year earlier. Meta said that figure would have been $7.40, higher by $3.57, without the one-time charge. Both numbers come straight from the company's release, so a reader can see the underlying business and the one-off side by side.

Where the $9.9 billion charge came from

Meta tied the $9.89 billion charge to an August 2026 agreement with 52 attorneys general over teen mental health and social media litigation. Chief financial officer Susan Li told analysts the charge was behind a higher tax rate in the quarter, "primarily driven by the nondeductible portion of legal expenses." It is a one-time settlement booked this quarter, not a change in how the advertising business runs.

The honest way to read the quarter is twice: once as reported, with the charge pulling margin to 20%, and once without it, where operating income would have been about $22.9 billion and the margin close to its usual high-30s range. Meta disclosed both, which makes the comparison clear rather than cosmetic.

The AI spending story

The figure that drew the most attention was not profit but spending. Capital expenditures, including principal payments on finance leases, reached $34.91 billion in the quarter, while operating cash flow was $32.79 billion. That left free cash flow at negative $2.12 billion, an unusual outflow for a company that normally generates cash in bulk.

The gap is deliberate. Meta is building data centers and buying chips to train and run AI models, and the bill now exceeds the quarter's cash generation. Li said the company plans to keep investing, telling analysts, "we expect to continue investing aggressively to support both our core business and emerging AI initiatives." Whether that spending pays off is the central question hanging over the company, and management is asking the market to judge it over years, not a single quarter.

Reality Labs and headcount

Reality Labs, the division behind Meta's headsets and smart glasses, posted an operating loss of $4,129 million for the quarter. Meta narrowed its full-year 2026 Reality Labs loss outlook to a range of $18 billion to $19 billion, which it said would be smaller than the 2025 loss.

Headcount was 66,775 at the end of September, down 15% from a year earlier. A smaller workforce next to record capital spending is the shape of the bet: fewer people, far more machines.

What the guidance says

Meta guided to fourth-quarter revenue of $73 billion to $76 billion, and said it assumes foreign currency will be roughly a 1% headwind to year-over-year growth. It raised full-year 2026 total expenses to $175 billion to $179 billion to reflect the legal charge, and narrowed full-year capital expenditures to $135 billion to $145 billion from a prior $130 billion to $145 billion. On profit, Li said, "excluding the Q3 legal charge, we continue to expect 2026 operating income to be above 2025 operating income." These are the company's own figures, reported here as guidance, not as a forecast of the share price.

The bigger picture

Meta is not alone. Across the group of large technology companies reporting third-quarter results in October 2026, the common thread is the same: strong revenue growth financing a historic wave of spending on AI data centers and chips. The debate for investors has shifted from whether these companies can grow to whether the returns on tens of billions of dollars of annual capital spending will show up, and when. Meta's negative free cash flow this quarter is the clearest example yet of that tension inside a single set of results. The company's answer, repeated by both Zuckerberg and Li on the call, is that the investment is deliberate and that the core business can fund it.

What to watch

The signal over the next few quarters is easy to name: whether revenue growth stays strong enough to carry the capital bill, and whether free cash flow returns to positive. Meta founder and chief executive Mark Zuckerberg framed the quarter in one line: "Our investments are paying off, the core business is strong, and we're seeing velocity across the board."

The advertising business is doing the work today. The spending is a claim on tomorrow. A reader weighing the company can track the two against each other each quarter rather than on any single day's price move. For the wider earnings season backdrop, see the Q3 2026 bank results.
