What Is Concentration Risk?
Concentration Risk is in an AI context, the risk that arises when an organisation — or a whole market — depends heavily on a small number of AI models, providers, or infrastructure, so that a single failure, outage, price change, or policy shift has outsized impact.

Because most AI applications rest on a handful of foundation-model providers and cloud platforms, a problem at one of them can cascade across many dependent organisations at once. Prudential regulators have begun treating this as systemic: APRA's April 2026 letter to Australian banks, insurers, and superannuation trustees specifically flagged over-reliance on a single AI provider and weak contingency planning. Managing it means knowing your AI dependencies, avoiding single points of failure, and keeping exit and fallback options open.
