Executive summary
A split economy can make headline markets look simpler than they are.
A K-shaped economy describes a split path. One group rises while another struggles to participate. In market terms, that can mean major indexes remain firm while many households, sectors, or companies experience a weaker reality underneath.
AI may accelerate this divide because software tools can spread quickly, capital markets can reprice business models quickly, and companies can change labor needs faster than in earlier industrial transitions.
That does not mean the whole economy changes overnight. It means the investment consequences can appear before the full labor, consumer, and social consequences are obvious.
