Competition and Antitrust Law Enforcement Reform Act of 2025
Read twice and referred to the Committee on the Judiciary.
This bill overhauls U.S. antitrust law by strengthening merger review standards, defining and banning broad “exclusionary conduct,” and authorizing substantial civil penalties for antitrust violations. It creates new FTC offices (Competition Advocate; Office of Market Analysis and Data), requires post-merger reporting and agency studies, expands whistleblower protections and rewards, bars predispute arbitration and class waivers for antitrust class actions, and increases funding for DOJ Antitrust and the FTC while directing future premerger filing fees to those agencies.
Penalties: left favors deterrence; right fears chilling legitimate business.
Relative to its intended legislative type, this bill is a comprehensive statutory reform package that is explicit in its problem statement, provides detailed statutory mechanisms and thresholds, integrates clearly with existing law, and builds significant measurement and reporting infrastructure.

Ambitious, high‑impact package that would provoke strong industry opposition and contentious floor and procedural fights; enactment plausible only after major narrowing and negotiation.
Relative to its intended legislative type, this bill is a comprehensive statutory reform package that is explicit in its problem statement, provides detailed statutory mechanisms and thresholds, integrates clearly with existing law, and builds significant measurement and reporting infrastructure. It leaves certain implementation particulars to agency guidance and future appropriations, and contains several rebuttable presumptions and discretionary elements that will require administrative detail or judicial interpretation in application.

Why the argument around this bill splits.
Penalties: left favors deterrence; right fears chilling legitimate business.
Likely strongly supportive.
The bill tightens merger standards, addresses monopsony and exclusionary conduct, increases enforcement resources, and strengthens whistleblower and worker protections—aligning with goals to curb concentration and protect consumers, workers, and small businesses.
Generally favorable but cautious.
The bill modernizes enforcement and data collection and provides clarity in some areas, but raises concerns about high statutory penalties, procedural safeguards, and implementation complexity that could produce unintended effects.
Likely opposed.
The bill substantially expands federal antitrust enforcement power, adds steep statutory penalties, broadens definitions of unlawful conduct, and channels ongoing industry fees to agencies—raising concerns about regulatory overreach, legal uncertainty, and harm to pro-growth business activity.
