India is building its AI ecosystem across five distinct layers: energy, infrastructure, compute, model development, and deployment. This 'full-stack' approach treats energy as the critical base layer, recognizing that massive compute needs require a robust and scalable power supply, which is a key national advantage.

The AI revolution isn't just about software. For the first time in years, venture capital is flowing into hardware like specialized semis and even into energy generation, because power is the core bottleneck for all AI progress.

Huang reframes massive AI spending not as a bubble but as essential infrastructure buildout. He describes a five-layer stack (energy, chips, cloud, models, applications), arguing that large investments are necessary to build the entire foundation required to unlock economic benefits at the application layer.

Historical tech cycles like the cloud and mobile demonstrate a consistent pattern: the application layer ultimately generates 5 to 10 times the value of the underlying infrastructure capital expenditure. With trillions being invested in AI infrastructure, future value creation at the application layer will be astronomically larger.

Jensen Huang's analogy frames AI not as a single technology but a full stack: energy, chips, infrastructure, models, and applications. This powerful mental model clarifies the distinct roles and investment opportunities at each layer of the AI economy, from utility companies to consumer-facing software.

The AI value stack has evolved from chips (NVIDIA) to models (OpenAI). The next critical phase is the application layer. It's unclear if value will be captured by new application companies or if the underlying model providers will absorb all the profits, a key question for investors and founders.

While NVIDIA CEO Jensen Huang conceptualized the 'five-layer AI cake' (apps, models, infrastructure, chips, energy), Google's Alphabet is the only company successfully operating across all five layers. This deep vertical integration, from custom TPU chips to funding its own power plants, is its key competitive advantage, allowing it to outmaneuver the very company that defined the framework.

In 2026, the AI investment narrative will expand from foundational model creators to companies building applications and services. It also includes sectors enabling AI growth, such as energy generation and data centers, offering a wider range of investment opportunities beyond the initial tech giants.

Despite massive investment in chips (NVIDIA) and models (OpenAI), it is not yet clear where long-term value will concentrate. The entire stack is in flux. Models could be commoditized by open source, chips could face historical commoditization cycles, and new AI-native apps could capture the most value. We are only in the early innings of a 30-year shift.
