Suflicientarianism is a prominent approach in political philosophy and in policy analyses. However, it is virtually absent from the formal normative economics liter­ature. We analyse suflicientarianism axiomatically in the context of the allocation of opportunities (formalised as chances of success). We characterise the core sufli­cientarian criterion, which counts the number of agents who attain a "good enough" chance of success. The characterising axioms shed new light on the key ethical con­stituents of suflicientarianism: they express a liberal principle of non-interference, a form of minimal respect for equality, and a form of separability across individuals. Given the large indifference classes inbuilt in the core version, we also discuss two alternative social opportunity relations that refine the suflicientarian intuitions: the multi-threshold suflicientarian ordering and an incomplete relation focusing only on the suflicientarian strict preferences
