Washington, D.C. — Ahead of today’s Senate Antitrust Subcommittee’s “Competition Policy for the Twenty-First Century: The Case for Antitrust Reform” hearing, the American Economic Liberties Project released a new dataset that finds that more than 80 percent of U.S. corporations valued at more than $100 billion have faced antitrust scrutiny at some point in the last thirty years, including monopolization claims, merger challenges, price fixing suits, and no-poach suits.

“This dataset shows that when firms are too big, they tend to abuse their dominance through illegal business practices,” said Matt Stoller, Director of Research at the American Economic Liberties Project. “One way to stop the problem of corporate bigness from getting worse is to bar firms above certain size thresholds from engaging in mergers. Currently, stopping a merger requires costly antitrust litigation, significant prosecutorial discretion, and unwieldy rule of reason analysis by judges unequipped to handle market analysis.”

“This dataset provides support for a Congressional ban on mergers above a certain size,” added Stoller. “Legislative reform that holds certain business practices by dominant firms to be an illegal abuse of dominance would help protect against predatory conduct.”

The dataset shows why a merger ban on companies valued at more than $100 billion is critical to rebalancing power in our economy towards working people, small businesses, and communities across the country. The dataset includes everything from Apple, valued at $1.953 trillion, to Walmart, valued at $361.81 billion, and Comcast, valued at $254.112 billion.

The American Economic Liberties Project works to ensure America’s system of commerce is structured to advance, rather than undermine, economic liberty, fair commerce, and a secure, inclusive democracy. Economic Liberties believes true economic liberty means entrepreneurs and businesses large and small succeed on the merits of their ideas and hard work; commerce empowers consumers, workers, farmers, and engineers instead of subjecting them to discrimination and abuse from financiers and monopolists; foreign trade arrangements support domestic security and democracy; and wealth is broadly distributed to support equitable political power.
