A natural monopoly is a monopoly in an industry in which it is most efficient (involving the lowest long-run average cost) for production to be concentrated in a single firm. This market situation gives the largest supplier in an industry, often the first supplier in a market, an overwhelming cost advantage over other actual and potential competitors, so a natural monopoly situation generally leads to an actual monopoly.
