This index measures market-implied expectations of acceleration in the development and commercialization of artificial intelligence. It aggregates prices from a set of prediction market contracts spanning frontier-model releases, leading AI-laboratory valuations and public-listing milestones, and AI infrastructure and tooling outcomes. Movements in the index reflect changes in market-implied probabilities of pro-acceleration realizations across these pathways, rather than forecasts for any single company or product. As a perpetual index, new markets are added through periodic reconstitution as constituents resolve, keeping it aligned with the evolving frontier of AI development.
