This Could Be the Most Undervalued AI Stock Heading Into 2026

Meta Platforms is positioning its 3.45 billion daily-user family of apps (up 8% year-over-year in Q3) as a high-value AI monetization engine, using its Llama large-language model to sharpen targeting and content recommendations; Q3 ad impressions rose 14% YoY, average ad price rose 10%, and total revenue climbed 26% YoY. Management has raised its AI spending outlook for 2025 and plans further increases in 2026 while investing in devices and advanced AI, with CEO Mark Zuckerberg forecasting a 5–7 year “paradigm shift.” The Motley Fool views Meta as an attractively valued way to play AI relative to pricier peers like Nvidia, Alphabet, Amazon and Microsoft, offering more downside resilience if AI stock valuations re-rate, noting the firm’s own disclosure of positions in several mentioned names.

Analysis

Meta Platforms reported 3.45 billion daily users as of Q3, a user base that grew 8% year‑over‑year and underpins its advertising model; third‑quarter ad impressions rose 14% YoY, average price per ad increased 10%, and total revenue grew 26% YoY, demonstrating rubric strength in core monetization. The company leverages its Llama large‑language model to improve audience targeting and content relevance, which management argues drives advertiser retention and higher budgets.

Management has raised its AI spending outlook for 2025 and signaled further increases in 2026 while investing in devices and longer‑term “superintelligence” initiatives; CEO Mark Zuckerberg projects a 5–7 year “paradigm shift,” implying elevated capex and R&D cadence that could compress near‑term margins but aim to expand long‑term addressable revenue.

Relative valuation is the focal point: the article positions Meta as attractively priced versus premium AI peers such as Nvidia, Alphabet, Amazon and Microsoft, and notes recent market weakness and AI bubble commentary that could cause volatile re‑rating across the sector; the combination of scale (billions of users) and improving ad metrics suggests greater downside resilience, while disclosure of Motley Fool’s positions and omission of Meta from its Top 10 list highlights potential analyst positioning and selection bias to consider.

Key Decisions for Investors

• Consider accumulating or overweighting Meta relative to high‑multiple AI peers given 26% YoY revenue growth, improving ad metrics and a large, growing daily user base
• Monitor upcoming quarterly prints for ad impressions, average price per ad and daily active user trends as primary leading indicators of revenue momentum
• Track management guidance on AI spending for 2025 and 2026 and disclosed device investments closely, as increased capex/R&D could pressure margins and change risk‑reward
• Maintain defensive sizing or hedge broader AI exposure in case of a sector re‑rating driven by bubble concerns, because the article flags recent market weakness and valuation risk
