The simulated bench finds for Plaintiffs on this phase issue. This is a simulated fictional output, not a prediction of any real ruling.
Burden. Plaintiffs bear the burden. They "must prove that Amazon has monopoly power in a properly defined antitrust market" [DKT-289]. Under the trial premise, the SAC's allegations are the record unless the SAC, DKT-159 or DKT-289 contradicts them.
Online superstore market. The market rests on a distinct demand feature. Online superstores "compete to build long-term relationships with consumers across multiple purchases of a variety of items" [SAC].
Amazon's challenges are inferences, not contradictions:
- The SAC concedes that other stores "may price certain items comparably with online superstores" [SAC]. It also states that shoppers "do not seriously consider those stores as reasonable alternatives" [SAC].
- Physical stores serve as a benchmark in Amazon's documents. Being a benchmark does not make them substitutes.
- The grocery carve-out is supported by the finding that "Amazon generally sets regional prices for perishable grocery items" [SAC].
- The Walmart+ allegation is paired with the finding that rivals "have struggled to make serious inroads" [SAC].
The record contains no quantitative cross-elasticity evidence. The direct evidence fills that gap. Nessie "generated enormous profits for Amazon even though its higher prices caused Amazon’s unit sales to decrease" [SAC]. Amazon degraded quality while "not losing meaningful numbers of shoppers to rivals" [SAC]. The 20% follow-rate threshold does not show that rivals disciplined Amazon's prices.
Shares. Amazon's share is "well above 60%—and rising" [SAC]. On an admittedly overinclusive set, "Amazon still had a 60.8% share" [SAC]. No measure in the record falls below that level.
Marketplace services. "SaaS providers, unlike online marketplace service providers, do not provide access to an established U.S. customer base" [SAC]. Amazon's argument that fulfillment fees belong to a separate market has some force against the fee-increase evidence. However, power does not depend on those fees. Amazon holds "a market share of greater than 66% of marketplace sales" [SAC], measured by third-party data and protected by pleaded barriers.
The direct-to-consumer channel argument is not supported by the record. The SAC pleads that sellers keep Amazon and set their prices elsewhere to match it, rather than leaving Amazon for those channels.
Conclusion. Both markets are valid on this record, and Amazon holds monopoly power in each.
