AI Stock Bubble Index

We track the tension between market expectations and business evidence across AI stocks, compute spending, funding, concentration, and adoption.

Pre-launch points are retrospective estimates using methodology v0.1. The latest point is the first published observation.

Spending is visible. Returns are less clear.

The index is highest where evidence is easiest to observe: infrastructure commitments and valuation pressure. It is lower where real revenue and adoption provide a counterweight.

  • Risk signal

    AI infrastructure intensity is the highest component at 90/100.

  • Risk signal

    Valuation pressure remains elevated at 65/100.
