Who is the largest federal contractor in FY2021?

Lockheed Martin Corporation, with $40.8B in contract-coded obligations in FY2021, ahead of The Boeing Company at $22.8B.

Why are big grant recipients missing from this list?

This ranks CONTRACT dollars only. Universities, states and health systems receive enormous federal ASSISTANCE, which is ranked separately at /rankings/top-grant-recipients so neither list crowds out the other.

Where does this ranking come from?

It is computed from USASpending.gov award records, which are U.S. government works and in the public domain. Each figure is the recipient's contract-coded obligations for FY2021. TheFiscalFinder does the ranking; the underlying figures are the government's own.

How many contractors are shown?

The top 100 for FY2021. Each row opens that contractor's own page, where the same money is broken out by year, by counterparty and by place.

Does a high position mean anything is wrong?

No. This is a description of where public money went in FY2021, computed from public records. It is not an allegation about anyone on it.
