- Meta Platforms Inc. (NASDAQ: META) will report third-quarter results on October 21, with investors watching whether growth in its advertising business can offset the cost of expanding its AI infrastructure as Wall Street increasingly demands evidence that heavy technology spending will generate sustainable returns.
Meta’s upcoming earnings report arrives as investors reassess the economics of the artificial intelligence boom. The company has committed substantial resources to data centers, computing equipment and AI development, leaving its ability to translate those investments into higher profits a central question for shareholders.
The company announced October 21 as its third-quarter earnings date, with results due after the US market closes. Its conference call is scheduled for 4:30 p.m. Eastern time.
Meta’s second-quarter results showed that its core advertising business remained strong, but spending increased faster than revenue. Revenue reached $60.8 billion, up 28% from a year earlier, while total costs and expenses climbed to $42.0 billion. Operating income fell 8% to $18.8 billion, according to the company’s second-quarter earnings release.
Those figures frame the challenge facing management: AI investments are intended to improve advertising, engagement and future products, but the associated infrastructure and operating costs are already affecting reported profitability.
Meta’s AI Capital Spending Raises the Stakes for Q3
Meta expects 2026 capital expenditures of $130 billion to $145 billion, including principal payments on finance leases, according to its latest second-quarter guidance. The company said the spending supports its AI initiatives and core business, including infrastructure required to develop and deploy AI systems.
The investment comes as major technology companies compete for computing capacity and data-center infrastructure. Meta is using AI across its apps, including to improve content recommendations and advertising performance. Its financial results suggest those improvements can support revenue growth, although the extent to which they will offset higher costs remains an important question for investors.
The spending outlook also needs to be viewed alongside Meta’s cash generation. In the second quarter, capital expenditures totaled approximately $31.1 billion, while cash, cash equivalents and marketable securities stood at $90.3 billion at the end of June. Meta also reported $83.7 billion in long-term debt in its SEC filing.
These figures do not by themselves indicate a financing problem. They do, however, show why investors are scrutinizing how quickly the company’s AI infrastructure investments can produce additional revenue and operating income. Meta has said its available funds, operating cash flow and financing resources should be sufficient to cover its expected needs.
The broader market is also becoming more selective about AI spending. Investors have increasingly questioned whether the revenue generated by AI services will justify the capital required to build them, a concern that has weighed on sentiment across technology and semiconductor shares. Meta’s results will provide another measure of how the spending translates into financial performance.
Advertising Growth Must Offset Rising Costs
Meta’s advertising business remains the primary source of revenue supporting its investment program. In the second quarter, the company attributed its 28% revenue increase largely to higher advertising revenue, with growth in ad impressions and average advertising prices both contributing.
For the third quarter, management previously guided to revenue of $61 billion to $64 billion. That range gives investors a benchmark for assessing whether the company can sustain strong sales growth while absorbing higher infrastructure expenses and other operating costs.
The profitability question extends beyond revenue. Investors will also examine operating income, margins, capital expenditure guidance and management’s comments about spending in the final quarter of the year. Any change to the full-year outlook could influence expectations for how much profit Meta can generate while continuing to expand its AI capacity.
The company has said it expects full-year 2026 operating income to exceed its 2025 level, despite the higher cost outlook. Whether third-quarter results support that expectation will be central to the earnings discussion.
Meta’s report is scheduled to come before results from several other large technology companies, making it an early test of investor appetite for continued AI investment. The figures will not settle the longer-term question of AI returns, but they should provide updated evidence of whether advertising growth is keeping pace with the cost of building the infrastructure behind Meta’s strategy.
