Ranked by federal prime contract dollars as a small business since FY2024 (USAspending.gov, as of Nov 5, 2026).

How these are ranked

Prime contract dollars since fiscal year 2024 on contracts where USAspending.gov counts the firm as a small business. “Small” is set per NAICS code: these firms are registered small under their primary code (or SBA-certified). Firms that hold small business subcontracting plans, which only businesses that aren't small file, or have $1 billion or more in these contracts are left out. A profile's yearly totals count all of its prime contracts, so they can be higher.
