Celler–Kefauver Act is a United States federal law passed in 1950 that reformed and strengthened the Clayton Antitrust Act of 1914 which had amended the Sherman Antitrust Act of 1890. The Celler–Kefauver Act was passed to close a loophole regarding asset acquisitions[1] and acquisitions involving firms that were not direct competitors. While the Clayton Act prohibited stock purchase mergers that resulted in reduced competition, shrewd businessmen were able to find ways around the Clayton Act by simply buying up a competitor's assets.[2] The Celler–Kefauver Act prohibited this practice if competition would be reduced as a result of the asset acquisition.

Sometimes referred to as the Anti-Merger Act, the Celler–Kefauver Act gave the government the ability to prevent vertical mergers and conglomerate mergers which could limit competition.
