The federal government regulates oligopolies through antitrust law enforcement. The acquisition of Unobtainium Corporation of Georgia by Adamantium Corporation of Alabama must not violate antitrust laws. Three main antitrust laws prohibit business practices that deprive local consumers of competitive market benefits. The market structure of Adamantium is an oligopoly. The penalties for violating the Sherman Act include a fine of up to $100 million and 10 years in prison.
