AI Value Chain US-50
How to Read the Index
The AI Value Chain US-50 tracks the aggregate performance of 50 publicly listed U.S. companies mapped across the AI value chain. This is not an AI "sector" index—it captures economic exposure to AI as a distributed system spanning infrastructure, platforms, and applications.
What the AI Value Chain US-50 Represents
The AI economy operates as a distributed value chain where infrastructure enables platforms, platforms enable applications, and applications drive demand back through the stack.
The AI Value Chain US-50 maps companies based on their economic exposure to AI value creation, not thematic labeling. A semiconductor company and a software company may both contribute to AI economic activity through different value chain layers.
This approach reveals how capital moves through the AI stack as an interconnected system rather than isolated industry segments.
How the Index is Constructed
The index aggregates performance across 50 companies mapped to the AI value chain. Performance reflects market-weighted price movement, designed to show how capital allocates across the AI ecosystem.
Construction emphasizes economic participation in AI value creation rather than revenue percentages or thematic classifications. Companies are included based on their structural position within the AI value chain, not their AI marketing messaging.
The index is updated weekly and expressed as a percentage return over the period.
How to Read the Weekly Return
A positive weekly return means the aggregate market value of the 50 companies increased over that week. A negative return means it decreased. This is mechanical price movement, not a judgment about AI progress or company quality.
A single week's return does not imply a trend or signal. Weekly returns capture market sentiment, capital allocation decisions, and short-term price movements—not fundamental AI development or long-term value creation.
Position each weekly return as a snapshot of how capital moved through the AI value chain during that period.
How to Read the Graph
The graph shows aggregate movement over time, revealing patterns in how the market values AI value chain companies as a system. Focus on relative movement and inflection points rather than exact values.
Look for periods of acceleration, deceleration, or directional changes. These inflections may reflect shifts in market perception about AI economic potential or capital allocation priorities.
Compare this movement with other ClearTake indicators to understand whether changes reflect broad AI economy dynamics or specific value chain layer effects.
What This Index Is — and Is Not
The AI Value Chain US-50 is:
- A structural lens for understanding how the AI economy moves as a system
- A descriptive tool showing capital flows through the AI value chain
- An aggregate measure of market-weighted performance across AI-exposed companies
The AI Value Chain US-50 is not:
- A predictive tool for future AI performance
- A judgment about valuation quality or profitability
- A method for distinguishing long-term winners from losers
- A benchmark for individual investment decisions
The index provides a system view of AI economic activity through the lens of public market capital allocation.
