Meta Platforms (META) will report third-quarter 2026 earnings after the U.S. market close on Oct. 21, testing whether advertising growth can offset sharply higher AI infrastructure spending and whether Muse adoption supports monetization, factors that could pressure free cash flow.
Guidance and Street Estimates
Meta has guided third-quarter revenue between $61 billion and $64 billion, setting the benchmark for investors to assess if ad sales can absorb rising AI costs. Analysts estimate revenue near $63.4 billion, implying about 23.8% year-over-year growth. Net income projections cluster around $15.4 billion, roughly 17% below the prior year.
Previews place capital spending near $41.7 billion for the quarter and expect free cash flow to decline by approximately $8.5 billion, a sharp reversal from the $784 million generated in the second quarter.
AI Spending and Muse Adoption
Meta’s 2026 capital-expenditure guidance ranges from $130 billion to $145 billion, reflecting ongoing investments in data centers, computing capacity, and AI infrastructure. The company also projects total expenses between $165 billion and $169 billion, excluding a separately reported legal charge. A secondary report cited an estimated $10 billion third-quarter legal expense related to settlements involving youth-harm claims and actions by 29 state attorneys general.
In September 2026, Meta launched Muse, a personal AI assistant offering a free version alongside paid subscription tiers reportedly priced at $20 and $100 per month. Muse reportedly exceeded 5 million downloads within its first month and approached 9 million since its debut. Analyst previews estimate a 14-day retention rate of about 20%, a key metric for converting downloads into paid subscriptions or business use.
Previews describe healthy advertising demand, with AI-powered recommendations, targeting, and creative tools contributing to ad growth. Investors will focus on margins and cash flow, watching for signs that Muse moves beyond downloads into paying users or enterprise adoption. If advertising momentum weakens, the company’s elevated spending could pressure profitability and liquidity.
