Do you or your competitor have a monopoly in a particular market? If so, your conduct or their conduct might enter the territory of the Sherman Act—Section 2—called monopolization.
If you are in Europe or other jurisdictions outside of the United States, instead of monopoly, people will refer to the company with extreme market power as “dominant.”
Of course, it isn’t illegal itself to be a monopolist or dominant (and monopoly is profitable). But if you utilize your monopoly power or obtain or enhance your market power improperly, you might run afoul of US, EU, or other antitrust and competition laws.
In the United States, Section 2 of the Sherman Act makes it illegal for anyone (person or entity) to “monopolize any part of the trade or commerce among the several states, or with foreign nations.” But monopoly, by itself, is not illegal. Nor is it illegal for a monopolist to engage in competition on the merits.
As an aside, I have heard, informally, from companies that are considered “dominant” in Europe that the label of “dominant” effectively diminishes their ability to engage in typical competitive behavior because they are under such heavy scrutiny by EU Competition authorities.
In the United States, monopolists have more flexibility, but they are still under significant pressure and could face lawsuits or government investigations at any time, even when they don’t intend to violate the antitrust laws. There is often a fine line between strong competition on the merits and exclusionary conduct by a monopolist.
- The possession of monopoly power in the relevant market.
- The willful acquisition or maintenance of that power as distinguished from growth or development as a consequence of a superior product, business acumen, or historic accident.
The Possession of Monopoly Power in the Relevant Market
To determine whether an entity has monopoly power, courts and agencies usually first define the relevant market, then analyze whether the firm has “monopoly” power within that market.
But because the purpose of that analysis is to figure out whether certain conduct or an arrangement harms competition or has the potential to do so, evidence of the actual detrimental effects on competition might obviate the need for a full market analysis. If you want to learn more about this point, read FTC v. Indiana Federation of Dentists (and subsequent case law and commentary). Now that I think about it, this should probably be a future blog post.
