>In many jurisdictions, such as the United States, there are laws restricting monopolies. Being the sole or dominant player in a market is often not illegal in itself. However, certain categories of monopolistic behavior can be considered abusive in a free market, and such activities will often attract the monopoly label and legal sanctions to go with it.
While it is correlated, monopolistic behavior is not always from a monopoly. Suppliers in free markets can still exhibit monopolistic behavior without being a monopoly.
