The GPU shortage succeeded where no manifesto had. It turned "decentralized AI", until recently just a slogan, into a real market. High-end accelerators have been out of stock for months, with lead times stretching past a year, and that scarcity pushed developers toward networks that pool idle hardware from around the world. Except the label "decentralized AI platform" now covers very different realities, and confusing them is the surest way to pick the wrong one. Renting a GPU is not the same as training a model. Scoring machine-learning outputs is not hosting an unrestricted LLM. This guide sorts the main players of 2026 by what they actually do, weighs the strengths and blind spots of each, and sets an outsider, Qubic, against the rest: the only network on this list where mining itself trains neural networks. No investment advice follows, only a map of the landscape.
