A monopoly in its purest form is one in which a single firm controls the whole industry. However, from an antitrust standpoint, even a corporation with a 25% market share might be called monopolistic.

A monopoly refers to a market structure where a single seller or producer dominates the entire industry, having exclusive control over the supply of a particular product or service. In a monopoly, there is no direct competition, granting the monopolistic entity considerable influence over pricing and market dynamics. This lack of competition can result in higher prices, reduced consumer choices, and potentially stifled innovation. Monopolies can emerge through various means, including barriers to entry, control over essential resources, or even government-granted privileges. Governments often regulate monopolies to prevent abuse of market power, promote fair competition, and protect consumer interests through antitrust laws and regulatory measures.

A monopoly is a market structure where a single company or entity dominates the entire market for a particular good or service, facing little to no competition. This dominant position allows the monopoly to control prices, supply, and other market factors, often leading to higher prices and reduced choices for consumers. Monopolies can arise from various sources, such as government regulation, control of a key resource, or technological superiority. While monopolies can benefit from economies of scale and significant profits, they are often criticized for stifling innovation, creating inefficiencies, and leading to unfair market practices. Regulatory bodies frequently intervene to prevent or dismantle monopolies to protect consumer interests.
