Meta Platforms shares rose as much as 5% in after-hours trading on October 21, 2026, after the Facebook and Instagram parent reported third-quarter revenue above Wall Street expectations and forecast continued growth for the final quarter of the year. Meta generated $64.60 billion in revenue, up 26% year-over-year, beating analysts’ expectations of approximately $63.3 billion. Investors also responded to the company’s expanding artificial intelligence strategy, including its new Muse AI assistant and Muse Wonder model.
However, the results were more complicated than the headline stock reaction suggests. Meta’s operating income fell 37% to $12.99 billion after the company recorded a $9.89 billion legal-settlement charge related to litigation over teen mental health and social media. Capital spending on AI infrastructure also remained substantial, and free cash flow turned negative. Despite these pressures, investors appeared encouraged by advertising growth, stronger-than-expected revenue and the company’s outlook for the fourth quarter.
Key Takeaways
- Shares rise after earnings: Meta stock climbed as much as 5% in after-hours trading following the October 21 results.
- Revenue beats estimates: Third-quarter revenue increased 26% to $64.60 billion.
- Reported operating income falls: Operating income declined 37% to $12.99 billion, partly because of a $9.89 billion legal charge.

Why Did Meta Stock Rise After Earnings?
The market reaction reflected the strength of Meta’s underlying revenue growth and its ability to generate more advertising revenue from its existing platforms.
Meta’s advertising business continues to benefit from AI-powered recommendations, improved ad targeting and better monetization across Facebook, Instagram and other applications. Higher ad impressions indicate that more advertising was delivered, while the increase in average price per ad suggests advertisers were paying more on average.
Investors also received a forward-looking signal from Meta’s fourth-quarter revenue forecast. The company expects revenue between $73 billion and $76 billion, with the midpoint above the approximately $73.7 billion consensus estimate reported before the results.
The performance of Meta’s AI products also contributed to investor interest. CEO Mark Zuckerberg highlighted the launch of Muse and Muse Wonder, alongside the company’s broader efforts to build more capable AI systems and agents.
The after-hours move reached approximately 5% at its peak, although the stock’s gain fluctuated during trading. A short-term price increase reflects investors’ immediate reaction to the results, not a guarantee of future performance.
Meta Q3 2026 Earnings: Key Financial Results
Meta’s results showed strong revenue growth but significant pressure on operating profitability because of the legal charge and higher investment spending.
| Financial metric | Q3 2026 | Q3 2025 | Year-on-year change |
|---|---|---|---|
| Revenue | $64.60 billion | $51.24 billion | +26% |
| Operating income | $12.99 billion | $20.54 billion | -37% |
| Operating margin | 20% | 40% | -20 percentage points |
| Net income | $9.86 billion | $2.71 billion | +264% |
| Diluted earnings per share | $3.83 | $1.05 | +265% |
| Capital expenditures | $34.91 billion | $19.4 billion | Higher year-on-year |
| Free cash flow | -$2.12 billion | $10.6 billion | Turned negative |
Source: Meta’s Q3 2026 earnings release. Figures are rounded.
The rise in reported net income and earnings per share needs context. Meta’s effective tax rate was much lower than in the year-ago quarter, when a large one-time tax charge affected results. At the same time, the current quarter included a substantial legal-settlement expense.
These factors make the headline net-income growth rate less representative of the underlying operating trend than revenue and operating income considered together.
The $9.89 Billion Legal Charge Behind the Profit Decline
Meta recorded a $9.89 billion expense in the third quarter related to an agreement with US state attorneys general over litigation involving teen mental health and social media.
The agreement provides for payments of up to approximately $18.59 billion, subject to its terms. The charge significantly affected the quarter’s reported operating income and diluted earnings per share.
Without the charge, Meta said its operating income would have been approximately $22.88 billion rather than $12.99 billion. Diluted EPS would have been $7.40 rather than $3.83.
| Metric | Reported Q3 2026 | Excluding the legal charge |
|---|---|---|
| Operating income | $12.99 billion | $22.88 billion |
| Diluted EPS | $3.83 | $7.40 |
The adjusted figures help investors evaluate the company’s performance without the exceptional expense. They do not mean the legal cost disappears from Meta’s financial obligations, and they should not be confused with the company’s reported GAAP results.
Legal exposure also remains a risk for the business. The company faces ongoing scrutiny over social media safety, privacy and its impact on younger users.
Advertising Growth Continues to Drive Meta’s Business
Advertising remains Meta’s primary revenue engine, supported by Facebook, Instagram, Messenger and WhatsApp.
In the third quarter, advertising revenue reached approximately $63.06 billion, up around 26% year-over-year. Ad impressions increased 10%, while the average price per ad rose 14%.
These figures suggest that Meta benefited from both increased advertising volume and stronger pricing. Its AI systems help recommend content, improve user engagement and determine which ads are more relevant to particular audiences.
The company also reported that its Family daily active people averaged 3.64 billion in September, up 3% from a year earlier.
That audience scale is commercially important because advertisers can reach a vast user base across Meta’s applications. However, continued growth depends on maintaining user engagement, attracting advertising budgets and addressing regulatory and privacy concerns.
Muse AI and Meta’s Next Growth Opportunity
Meta is attempting to expand its business beyond traditional social media advertising by developing AI assistants and more capable AI models.
The company said more than 10 million people in the United States and Canada had set up accounts for its Muse assistant. Zuckerberg also highlighted Muse Wonder, which Meta describes as a frontier AI model.
AI agents could create new opportunities for Meta in shopping, subscriptions, enterprise services and other transactions. For example, an assistant that helps users research products and complete purchases could eventually support commerce-related revenue streams.
However, operating advanced AI assistants requires substantial computing resources. Zuckerberg acknowledged that Muse is compute-intensive and said Meta expects to improve its cost efficiency significantly over the coming year.
The commercial opportunity is therefore accompanied by execution risk. Meta needs to convert AI usage into sustainable revenue while controlling the costs of training and serving increasingly capable models.
Meta Raises Its AI Spending Outlook
Meta continues to invest heavily in data centers, servers, networking equipment and other infrastructure needed to train and operate AI models.
The company reported third-quarter capital expenditures of $34.91 billion. It also raised its full-year 2026 capital expenditure outlook to between $135 billion and $145 billion, compared with a previous range of $130 billion to $145 billion.
| Spending indicator | Amount |
|---|---|
| Q3 2026 capital expenditures | $34.91 billion |
| Previous full-year 2026 capex outlook | $130 billion–$145 billion |
| Updated full-year 2026 capex outlook | $135 billion–$145 billion |
| Q3 free cash flow | -$2.12 billion |
| Cash and marketable securities at quarter-end | $82.45 billion |
Source: Meta’s Q3 2026 earnings release and company commentary.
The scale of spending is one of the biggest questions facing Meta investors. AI infrastructure could strengthen advertising, improve recommendations and create new products, but those benefits must eventually justify the capital committed.
Meta’s negative free cash flow in the quarter highlights the near-term financial consequences of that investment and its legal expense. The company ended September with $82.45 billion in cash, cash equivalents and marketable securities, providing a substantial financial buffer.
Meta has also said it intends to shift investment away from parts of its Reality Labs business toward priority areas, primarily AI. It expects Reality Labs’ losses to narrow to around $15 billion in 2027.
What Meta’s Q4 Guidance Means
Meta expects fourth-quarter revenue between $73 billion and $76 billion. The midpoint of $74.5 billion is above the approximately $73.7 billion analyst consensus reported before the results.
The forecast indicates that management expects advertising demand and the company’s core business to remain strong into the final quarter of 2026.
However, revenue guidance does not guarantee higher profits. Meta expects continued investment in AI, and its total expense outlook for 2026 is now $175 billion to $179 billion, incorporating the legal-settlement charge.
Investors will therefore be watching not only whether revenue grows, but also whether Meta can translate that growth into sustainable operating income and cash generation while financing its AI ambitions.
The Bigger Picture
Meta’s latest results demonstrate the strength of its advertising business and the growing role of AI in improving monetization across its platforms. Revenue growth exceeded expectations, while the company’s fourth-quarter forecast suggested that demand could remain strong. These factors help explain why investors responded positively despite the decline in reported operating income.
The longer-term challenge is to balance AI investment with financial discipline. Meta is committing unprecedented amounts of capital to infrastructure while facing legal liabilities and growing competition in AI. If its models and agents generate meaningful new revenue and improve advertising efficiency, those investments could support future growth. If monetization develops more slowly than expected, elevated spending could continue to weigh on cash flow and profitability.

Looking Ahead
Meta’s next quarter will test whether its advertising momentum can continue while AI infrastructure spending remains elevated. Investors will look for evidence that improvements in recommendations and engagement are translating into additional advertising revenue, and that new products such as Muse can eventually contribute meaningful income. Legal expenses, infrastructure commitments and the trajectory of free cash flow will also remain important factors.
For shareholders, the central question is whether Meta can turn its AI investments into durable financial returns. The company’s strong revenue growth and upbeat fourth-quarter forecast provide support for its strategy, but the combination of heavy capital spending and legal exposure leaves meaningful uncertainty. The market’s initial positive reaction reflects optimism about future growth, while subsequent results will determine whether that optimism is sustained.
