> The FTC has failed to plead enough facts to plausibly establish a necessary element of all of its Section 2 claims — namely, that Facebook has monopoly power in the market for Personal Social Networking (PSN) Services. The Complaint contains nothing on that score save the naked allegation that the company has had and still has a “dominant share of th[at] market (in excess of 60%).” Redacted Compl., ¶ 64. Such an unsupported assertion might (barely) suffice in a Section 2 case involving a more traditional goods market, in which the Court could reasonably infer that market share was measured by revenue, units sold, or some other typical metric. But this case involves no ordinary or intuitive market. Rather, PSN services are free to use, and the exact metes and bounds of what even constitutes a PSN service — i.e., which features of a company’s mobile app or website are included in that definition and which are excluded — are hardly crystal clear. In this unusual context, the FTC’s inability to offer any indication of the metric(s) or method(s) it used to calculate Facebook’s market share renders its vague “60%-plus” assertion too speculative and conclusory to go forward. Because this defect could conceivably be overcome by re-pleading, however, the Court will dismiss only the Complaint, not the case, and will do so without prejudice to allow Plaintiff to file an amended Complaint.
Not sure what the FTC's game plan was going into an antitrust fight without a market share pitch.
