What Are the Top Lobbying Firms in the U.S.?

May 13, 2024

Despite the recent upheaval in Congress that thwarted action on many bills, 2023 was another record-breaking year of growth for the lobbying and public affairs industry. For the second consecutive year, federal lobbying spending topped $4 billion.

Biggest lobbying industries

The direct lobbying industry reacted to congressional inaction in 2023 by pivoting to instead focus on laying the groundwork for future legislation on major issues, including:

  • 2017 Tax Cuts and Jobs Act expiration
  • Farm bill reauthorization
  • Artificial intelligence regulations

The highest profile issue is the looming expiration of major provisions of the 2017 Tax Cuts and Jobs Act, which is already putting tremendous pressure on Congress to pass a major tax bill in 2025 no matter which party controls the government. Corporations and other interest groups with a stake in the outcome are proactively investing in relationship-building with influential tax-writing committee members in both the House and Senate.
