Originally published October 6, 2020. Technically restored September 4, 2026, with dated updates. The congressional report described below presented majority-staff findings and recommendations; it was not a judicial ruling that the companies had violated antitrust law.
The report scrutinized how four major technology companies accumulated and maintained power over online commerce, mobile software, social networking, search, and advertising.
On October 6, 2020, the Democratic majority staff of the House Judiciary Subcommittee on Antitrust released its nearly 450-page Investigation of Competition in Digital Markets. After a 16-month investigation, the staff concluded that Amazon, Apple, Facebook, and Google acted as gatekeepers over important channels of digital distribution and used that position in ways the report characterized as anti-competitive. The report itself cautioned that its conclusions were staff views and did not necessarily represent every committee member. ([democrats-judiciary.house.gov](https://democrats-judiciary.house.gov/sites/evo-subsites/democrats-judiciary.house.gov/files/migrated/UploadedFiles/Competition_In_Digital_Markets.pdf))
“Companies that once were scrappy, underdog startups that challenged the status quo have become the kinds of monopolies…”
That comparison to oil barons and railroad tycoons captured the report’s central argument: each company both operated important infrastructure and competed with businesses dependent on that infrastructure. The staff alleged that control over rankings, defaults, fees, commercial data, acquisitions, and access rules allowed the platforms to favor their own products and reinforce their market positions. Those were congressional findings and interpretations, not adjudicated facts. ([democrats-judiciary.house.gov](https://democrats-judiciary.house.gov/sites/evo-subsites/democrats-judiciary.house.gov/files/migrated/UploadedFiles/Competition_In_Digital_Markets.pdf))
The proposed remedies were correspondingly broad. The staff asked Congress to consider structural separation and line-of-business restrictions, nondiscrimination rules against self-preferencing, interoperability and data-portability requirements, presumptive limits on acquisitions by dominant platforms, stronger merger and monopolization laws, larger enforcement budgets, and fewer barriers to private antitrust suits. The report contemplated divestiture or the unwinding of completed acquisitions where legally justified, but it did not itself order any breakup. ([democrats-judiciary.house.gov](https://democrats-judiciary.house.gov/sites/evo-subsites/democrats-judiciary.house.gov/files/migrated/UploadedFiles/Competition_In_Digital_Markets.pdf))
Republicans did not join the majority report. Representative Ken Buck circulated a separate response that accepted some concerns about platform power while rejecting structural separation and several proposed changes to antitrust doctrine. Representative Jim Jordan issued a different report centered on allegations of anti-conservative content moderation. There was therefore some cross-party concern about technology platforms, but no bipartisan agreement on the relevant markets, legal conclusions, or remedies. ([judiciary.house.gov](https://judiciary.house.gov/sites/evo-subsites/republicans-judiciary.house.gov/files/2020-10/2020-10-06-JDJ-to-Nadler-re-Tech-Investigation.pdf?utm_source=openai))
Amazon
The majority staff concluded that Amazon had significant and durable power in United States online retail. A commonly cited 2020 estimate placed Amazon at 38.7 percent of domestic e-commerce, but the report argued that differences in market definition and incomplete data made estimates of 50 percent or more more credible. That higher figure was the staff’s assessment, not a settled measurement. ([democrats-judiciary.house.gov](https://democrats-judiciary.house.gov/sites/evo-subsites/democrats-judiciary.house.gov/files/migrated/UploadedFiles/Competition_In_Digital_Markets.pdf))
The report focused on Amazon’s dual role as marketplace operator and retailer. It alleged that Amazon could use nonpublic information generated by independent sellers to inform its own retail and private-label decisions, while also controlling search placement, the Buy Box, fulfillment services, advertising, and access to Prime customers. Amazon maintained that its policy prohibited retail teams from using nonpublic, seller-specific data to compete against sellers; the report cited former employees, sellers, internal documents, and published investigations in disputing whether that protection was effective. ([democrats-judiciary.house.gov](https://democrats-judiciary.house.gov/sites/evo-subsites/democrats-judiciary.house.gov/files/migrated/UploadedFiles/Competition_In_Digital_Markets.pdf))
The staff also argued that dependence on Amazon weakened sellers’ bargaining power. Its report said Amazon’s average share of each third-party sale had risen from an estimated 19 percent in 2015 to 30 percent by 2020 when commissions and services were included. It also examined price-parity mechanisms that allegedly discouraged sellers from offering lower prices elsewhere, while acknowledging that such provisions are not inherently anti-competitive in every setting. ([democrats-judiciary.house.gov](https://democrats-judiciary.house.gov/sites/evo-subsites/democrats-judiciary.house.gov/files/migrated/UploadedFiles/Competition_In_Digital_Markets.pdf))
Amazon rejected the report’s market definition and proposed remedies. In an October 6, 2020 response, it argued that physical and online retail compete in one broad market and that separating first-party retail from third-party marketplace sales would hurt sellers and consumers. “Large companies are not dominant by definition,” the company said. ([blog.aboutamazon.com](https://blog.aboutamazon.com/policy/fringe-notions-for-regulating-retail-would-destroy-small-businesses-and-hurt-consumers))
The report concluded that Facebook held monopoly power in a defined market for personal social networking and had protected that position by acquiring, copying, or restricting potential competitors. Facebook disputed that market definition, arguing that it competed against a much wider range of communications, entertainment, and social services. ([democrats-judiciary.house.gov](https://democrats-judiciary.house.gov/sites/evo-subsites/democrats-judiciary.house.gov/files/migrated/UploadedFiles/Competition_In_Digital_Markets.pdf))
The staff’s central acquisition example was Facebook’s 2012 purchase of Instagram. Internal communications showed Mark Zuckerberg discussing mobile apps such as Instagram that were “building networks that are competitive with our own.” In another exchange, Zuckerberg agreed that neutralizing a potential competitor was among the transaction’s purposes. The report treated those documents as evidence that Facebook regarded Instagram as a nascent threat; Facebook argued that its investment and infrastructure helped Instagram become far more successful. ([democrats-judiciary.house.gov](https://democrats-judiciary.house.gov/sites/evo-subsites/democrats-judiciary.house.gov/files/migrated/UploadedFiles/Competition_In_Digital_Markets.pdf))
The original article incorrectly connected the “Cunningham Memo” to Facebook’s strategy before the Instagram acquisition. The memo was written in October 2018, six years after Facebook bought Instagram. It examined competition and network effects among Facebook, Instagram, Messenger, and WhatsApp. A former Instagram employee told the subcommittee that the work influenced Facebook’s later growth strategy and reflected internal efforts to prevent Facebook and Instagram from competing too aggressively with each other. That account remained attributed testimony, not an independently adjudicated finding. ([democrats-judiciary.house.gov](https://democrats-judiciary.house.gov/sites/evo-subsites/democrats-judiciary.house.gov/files/migrated/UploadedFiles/Competition_In_Digital_Markets.pdf))
Facebook’s response to Recode emphasized that regulators had reviewed the Instagram and WhatsApp transactions, that the company had invested heavily in both services, and that competition remained strong. The company later made similar arguments when federal and state enforcers challenged those acquisitions.
The majority staff said Google held monopoly power in general online search and search advertising and described its linked products as an “ecosystem of interlocking monopolies.” The report did not treat every form of online marketing as one market; its analysis distinguished general search, search advertising, digital-advertising tools, mobile operating systems, browsers, and app distribution. ([democrats-judiciary.house.gov](https://democrats-judiciary.house.gov/sites/evo-subsites/democrats-judiciary.house.gov/files/migrated/UploadedFiles/Competition_In_Digital_Markets.pdf))
One allegation concerned specialized or “vertical” search providers, such as services devoted to restaurants, travel, or shopping. The report said Google viewed some of those businesses as competitive threats and used prominent search features and its control of rankings to divert traffic toward Google’s own services. Google disputed the characterization and said its search changes were intended to give users more useful answers. ([democrats-judiciary.house.gov](https://democrats-judiciary.house.gov/sites/evo-subsites/democrats-judiciary.house.gov/files/migrated/UploadedFiles/Competition_In_Digital_Markets.pdf))
The report also examined Google’s Android agreements. It alleged that contractual requirements governing preinstallation, placement, and default status helped extend Google’s search position from desktop computers to mobile devices while reducing opportunities for competing search engines and apps. Google argued that Android increased competition and that manufacturers and users retained choices. ([democrats-judiciary.house.gov](https://democrats-judiciary.house.gov/sites/evo-subsites/democrats-judiciary.house.gov/files/migrated/UploadedFiles/Competition_In_Digital_Markets.pdf))
Apple
The staff’s Apple analysis focused on the distribution of native iOS apps, not on a claim that Apple monopolized every business in which it operated. In 2020, Apple was the leading United States smartphone vendor, and iOS or iPadOS ran on more than half of domestic smartphones and tablets under the measurements cited by the report. Because the App Store was then the sole authorized channel for distributing native apps to ordinary iOS users, the staff concluded that Apple exercised monopoly power over iOS app distribution. Apple rejected that market definition and pointed to competition among devices and software platforms. ([democrats-judiciary.house.gov](https://democrats-judiciary.house.gov/sites/evo-subsites/democrats-judiciary.house.gov/files/migrated/UploadedFiles/Competition_In_Digital_Markets.pdf))
The report alleged that Apple used App Store review, ranking, technical-access, and payment rules to disadvantage some developers while favoring its own services. It also criticized Apple’s commissions. At the time, Apple generally charged 30 percent on paid apps and in-app purchases of digital goods and services; qualifying subscriptions fell to 15 percent after their first year. The 30 percent figure therefore did not apply to every app, transaction, or developer. ([democrats-judiciary.house.gov](https://democrats-judiciary.house.gov/sites/evo-subsites/democrats-judiciary.house.gov/files/migrated/UploadedFiles/Competition_In_Digital_Markets.pdf))
The conflict became especially visible in August 2020, when Epic Games added a direct-payment option to Fortnite intended to bypass Apple’s in-app purchasing system. Apple removed Fortnite from the App Store, and the companies filed competing lawsuits. In its contemporary response to the House report, Apple denied holding a dominant share in the broader markets where it competed and defended its commissions as comparable to those charged by other software and gaming marketplaces.
What happened next
The report had no immediate legal force, but several proceedings it anticipated—or concerns closely related to them—became major government cases.
On October 20, 2020, the Justice Department and eleven states sued Google over its search-distribution agreements. On August 5, 2024, a federal district court held that Google had unlawfully maintained monopolies in general search services and general search text advertising. The court ordered remedies in September 2025, including restrictions on exclusive distribution contracts and requirements to provide certain data and syndication services to qualified competitors; a final judgment followed on December 5, 2025, with implementation proceedings continuing in 2026. These judicial findings established specific violations alleged in that case, not every claim made by the House report. ([justice.gov](https://www.justice.gov/archives/opa/pr/justice-department-sues-monopolist-google-violating-antitrust-laws?rel=outbound&utm_source=openai))
In a separate case filed in 2023, another federal court held on April 17, 2025, that Google had monopolized open-web digital-advertising markets. Remedy proceedings followed. ([justice.gov](https://www.justice.gov/opa/pr/department-justice-prevails-landmark-antitrust-case-against-google?utm_source=openai))
The Federal Trade Commission sued Facebook, now Meta, in December 2020, alleging that the Instagram and WhatsApp acquisitions and restrictions imposed on developers helped maintain a personal-social-networking monopoly. The FTC’s latest cited case-page update, dated December 2, 2025, listed the matter as pending after a 2025 trial and post-trial submissions. The allegations should therefore not be described as established liability. ([ftc.gov](https://www.ftc.gov/legal-library/browse/cases-proceedings/191-0134-facebook-inc-ftc-v-ftc-v-meta-platforms-inc?utm_source=openai))
The FTC and state attorneys general sued Amazon in September 2023, alleging that marketplace and pricing practices illegally maintained monopolies in defined online-superstore and marketplace-services markets. Amazon denied the allegations. The Justice Department and a group of states separately sued Apple on March 21, 2024, alleging monopolization of smartphone markets; Justice Department planning documents described that litigation as continuing in 2026. Those complaints are allegations unless and until resolved by a final judgment. ([ftc.gov](https://www.ftc.gov/legal-library/browse/cases-proceedings?search=Amazon&sort_by=search_api_relevance&utm_source=openai))
The lasting insight of the 2020 report was structural rather than company-specific: when a platform both governs access to a market and competes within it, control over rankings, defaults, fees, commercial data, and participation rules can become a means of entrenching power. Whether a particular practice violates antitrust law still depends on the relevant market, evidence, governing doctrine, defenses, and adjudication in an individual case.
