Cartels
An oligopoly can be construed as a cartel, which would be a violation of Sherman if it is deemed that the companies have organized and agreed not to compete. Price fixing, market sharing and other types of anticompetetive behavior are covered by these sections of antitrust law.
This section of the law was used in the early 90's against the airlines.
