Warren Calls for Stronger AI Antitrust Enforcement and Greater Transparency in US Merger Reviews

Speaking in Washington, the Massachusetts Democrat argued that existing antitrust laws should be applied aggressively to emerging technologies, warning that companies should not be shielded from competition enforcement simply because pricing or business decisions rely on artificial intelligence.

“Corporations don’t get a free pass from antitrust just because they’re using an algorithm,” Warren said during her remarks. She pointed to concerns about the use of AI-powered pricing tools in the housing market, arguing that regulators should intervene if such technology is used to unlawfully increase rental costs during a period of persistent housing affordability challenges.

According to Bloomberg, Warren’s speech also called for Congress to strengthen the powers available to federal antitrust agencies and modernize merger oversight by requiring greater public disclosure during government reviews of corporate acquisitions.

The senator’s comments come after recent federal enforcement actions involving algorithmic pricing software. During former President Joe Biden’s administration, the U.S. Department of Justice filed lawsuits alleging that software platforms enabled unlawful price coordination in both the apartment rental and meat industries by facilitating the sharing of nonpublic pricing information among competitors. Bloomberg reported that the Justice Department under President Donald Trump has since reached settlements resolving both cases.

The litigation reflected growing scrutiny from antitrust regulators over whether algorithm-driven pricing systems can facilitate anti-competitive conduct without traditional forms of direct coordination. Federal officials have increasingly argued that technology does not exempt companies from longstanding competition laws when business practices may reduce market competition or raise prices for consumers.

State lawmakers have also begun responding to those concerns. According to Bloomberg, legislatures in states including California, Connecticut and New York have proposed or revised laws restricting the use of pricing software that aggregates confidential market information to generate recommended prices. Congress, however, has not enacted comparable federal legislation addressing the issue.

Beyond artificial intelligence, Warren used her speech to criticize growing economic concentration across multiple industries, arguing that a relatively small number of companies exert significant influence over sectors ranging from healthcare and housing to digital services and media.

She also proposed changes to the federal merger review process aimed at making antitrust enforcement more transparent. Current U.S. law requires companies pursuing mergers above specified financial thresholds to notify federal antitrust agencies and observe a waiting period before completing their transactions. However, much of the review process remains confidential unless regulators challenge a deal in court or negotiate a public settlement.

According to Bloomberg, Warren contrasted the U.S. system with merger review frameworks in Europe and the United Kingdom, where regulators routinely publish information about transaction filings, review timelines and key procedural milestones. She argued that Congress should require similar public disclosure in the United States, including notification of merger review deadlines and greater visibility into enforcement decisions.

The senator also urged lawmakers to strengthen oversight of antitrust settlements and simplify legal procedures for unwinding mergers that are later determined to violate competition laws.

The remarks align with Warren’s longstanding advocacy for stronger antitrust enforcement and increased scrutiny of corporate concentration. Throughout her Senate tenure, she has supported legislative proposals to expand enforcement authority at the U.S. Department of Justice and the Federal Trade Commission, while arguing that stronger competition policy can help address rising consumer prices and concentrated market power.
