The AI Hype Cycle and Its Impact on Tech Sector Valuations: Identifying Undervalued Stocks Amid Waning Optimism

The artificial intelligence (AI) landscape in 2025 is at a pivotal inflection point. According to Gartner's 2025 Hype Cycle for Artificial Intelligence, generative AI (GenAI) has entered the Trough of Disillusionment, as organizations grapple with proving its business value despite massive investmentsGartner Hype Cycle for AI 2025^[1]. Meanwhile, investor sentiment toward AI-driven tech stocks remains robust, with companies like NVIDIA, Microsoft, and Meta reporting record-breaking financial resultsTech Sector Navigates Q2/Q3 2025: AI Hype Fuels Record Gains^[2]. However, the maturation of the AI hype cycle is shifting focus toward foundational enablers—such as AI-ready data, ModelOps, and AI trust, risk, and security management (TRiSM)—creating opportunities for investors to identify undervalued stocks in these critical areas.

The Hype Cycle's Evolution and Investor Sentiment

The Gartner Hype Cycle underscores a stark divergence in AI's trajectory. While generative AI faces skepticism due to unmet expectations, AI agents and multimodal AI are at the Peak of Inflated Expectations, driven by their potential to automate complex tasks and integrate diverse data typesAI Hype Cycle: Gartner Charts the Rise of Agents, ModelOps, Synthetic Data, and AI Engineering^[3]. This duality reflects a broader market reality: investors remain bullish on AI's transformative potential but are increasingly discerning about where to allocate capital.

Recent earnings reports validate this optimism. NVIDIA's Q3 2025 revenue surged to $35.1 billion, a 94% year-over-year increase, fueled by demand for its Blackwell architecture and data center solutionsTech Sector Navigates Q2/Q3 2025: AI Hype Fuels Record Gains^[2]. Microsoft's Azure cloud growth was similarly bolstered by AI services, contributing 16 percentage points to its Q2 2025 revenue growthTech Sector Navigates Q2/Q3 2025: AI Hype Fuels Record Gains^[2]. Meta's AI-driven advertising tools and Llama 4 model propelled its Q2 revenue to $47.52 billion, far exceeding expectationsTech Sector Navigates Q2/Q3 2025: AI Hype Fuels Record Gains^[2].

Foundational Enablers: The New Frontier for AI Investment

As the hype cycle matures, the focus is shifting from flashy applications to the infrastructure that sustains them. Foundational enablers—such as AI-ready data, ModelOps, and TRiSM—are emerging as critical components for scalable AI adoption. For instance, AI-ready data platforms are gaining traction as organizations recognize the need for high-quality, curated datasets to train effective modelsGartner Hype Cycle for AI 2025^[1]. Similarly, ModelOps tools are becoming indispensable for managing the lifecycle of AI models, ensuring agility and complianceAI Hype Cycle: Gartner Charts the Rise of Agents, ModelOps, Synthetic Data, and AI Engineering^[3].

TRiSM, which addresses ethical concerns and governance challenges, is another area of growing importance. Companies like CoreWeave (CRWV) are capitalizing on this trend by offering purpose-built AI data centers and infrastructure, enabling access to cutting-edge processors like NVIDIA's GB200 Blackwell SuperchipUndervalued and Ignored: 3 Artificial Intelligence (AI) Stocks to Watch^[5].
