The U.S. Department of Justice is signaling that antitrust enforcement will remain a central issue for Silicon Valley, including companies developing and commercializing artificial intelligence. At the 2026 Antitrust Tech Summit in San Francisco, Deputy Assistant Attorney General Stephanie A. Greco outlined the Trump administration’s approach to competition policy and emphasized the department’s continuing attention to major technology companies.
Greco delivered the remarks on October 15, 2026, during an event focused on competition in the technology industry. According to the U.S. Department of Justice, the discussion addressed enforcement work involving large technology companies, including ongoing litigation concerning Apple and Google.
The message from the department points to a regulatory environment in which the size and influence of digital platforms will continue to attract federal scrutiny. It also places artificial intelligence at the center of the debate, as AI companies expand their role in digital services, computing infrastructure and consumer markets.
Documentary evidence remains central to enforcement
One of the themes highlighted in Greco’s remarks was the importance of documentary evidence in antitrust work. That focus matters because competition cases often depend on how regulators and courts interpret internal records, business strategies and communications related to market behavior.
By emphasizing evidence and market competition, the Justice Department presented antitrust enforcement as a process grounded in the examination of business practices rather than in the technological novelty of a product alone. For companies operating in fast-growing areas such as artificial intelligence, that distinction may become increasingly important as regulators assess how new services are introduced and expanded.
The department’s position also suggests that the technology sector will not be treated as separate from traditional competition principles. Digital platforms and AI businesses may operate through different products and technical systems, but their conduct can still be examined through questions involving market power, access, competitive pressure and the effects on consumers and other companies.
Apple, Google and the wider technology sector
The Justice Department’s reference to ongoing litigation involving Apple and Google places the summit’s message within a broader federal effort focused on some of the most influential companies in the American digital economy. The cases illustrate how competition policy can reach businesses whose products are deeply integrated into everyday online activity.
For technology companies, antitrust scrutiny can affect more than courtroom strategy. It may influence decisions involving partnerships, acquisitions, product design and the organization of services. The possibility of enforcement can also become a factor in how investors evaluate companies whose growth depends on controlling important digital markets or infrastructure.
Greco’s remarks do not represent a final ruling in any individual case. They do, however, offer a public indication of the Justice Department’s priorities under the current administration and reinforce the department’s intention to continue examining competition in technology markets.
Why the AI market is becoming a key focus
Artificial intelligence is expanding across the technology industry, linking software applications with data centers, cloud services and consumer-facing products. That expansion has raised the importance of competition questions for businesses that depend on access to computing resources, distribution channels and large digital ecosystems.
The San Francisco summit therefore placed AI within the broader debate over the future structure of the U.S. technology market. As companies seek to develop and commercialize AI products, federal scrutiny may extend to the relationships and practices that shape how those products reach customers and compete with alternatives.
For Brazilian readers, the issue matters because decisions made by U.S. regulators can influence global technology companies whose services, platforms and infrastructure are also present in Brazil. Changes in the strategies of major American firms may affect product availability, partnerships, investment priorities and the competitive landscape for businesses connected to the digital economy.
What companies and investors may watch next
The Justice Department’s approach will be closely observed by technology executives, investors and companies that depend on major platforms. Continued litigation involving Apple and Google, together with closer attention to AI businesses, could help define how federal authorities interpret competition in markets changing at high speed.
The central question is whether innovation and expansion will occur in markets that preserve meaningful competitive opportunities. By highlighting documentary evidence, market competition and business practices, the department has indicated that those issues will remain important as the United States evaluates the next stage of Silicon Valley’s development.
