Where the dollars are awarded — by agency
The same obligated dollars, grouped by the awarding agency. The Department of Energy leads the ingested set by a wide margin because its national-laboratory management-and-operating contracts carry very large obligations.

Coverage — what this ranks, and what it does not
This ranks the 16,779 prime-award transactions (443 distinct recipients) that Fonteum has ingested from USASpending.gov so far — a bounded, growing slice of the federal universe, weighted toward large-dollar awards. It is not a completeness claim and not the official government ranking. For the authoritative, complete record of who the government pays, use usaspending.gov.
Methodology
The ranking sums obligation_amount across the current rows of the public.procurement_awardstable (the ingested USASpending.gov prime-award transactions), grouped by recipient and by awarding agency. Each share is the recipient's (or agency's) obligated total divided by the full ingested obligated total. Obligated dollars are the amounts the government has legally committed under its prime awards, as the source reports them. Every figure is re-derivable from the SQL sidecar below, whose expected-result comments match the committed JSON snapshot.

Top federal contractors — common questions
Who are the top federal contractors?
In Fonteum's ingested USASpending.gov prime-award set (queried 2026-06-20), the largest recipient by obligated dollars is Lockheed Martin Corp at $65,637,073,151 (10.65% of the set). The rest of the top of the table is dominated by Department of Energy national-laboratory management-and-operating contractors. This ranks the ingested sample, not the complete federal universe — confirm the authoritative full ranking at usaspending.gov.
What does 'obligated' mean on this ranking?
Obligated dollars are the amounts the government has legally committed to pay a recipient under its prime awards, as reported on USASpending.gov. Large management-and-operating contracts (such as the DOE national laboratories) carry very large obligations, which is why those operators sit at the top of the dollar ranking.
Is this the complete list of federal contractors?
No. This ranks the 443 distinct recipients across the 16,779 prime-award transactions Fonteum has ingested so far — a bounded, growing slice, not the complete federal record. The authoritative, complete spending data is published at usaspending.gov; this page links to it.
Does a high obligation mean a contractor did anything wrong?
No. A high obligated-dollar total is a neutral fact about federal spending — it reflects the size of the work the government has contracted for, not a judgment about the contractor. This ranking assigns no score and makes no determination about any party.
How can I reproduce this ranking?
Every figure is re-derivable in Postgres from the published SQL (linked on this page) against the public.procurement_awards table — plain GROUP BY aggregation with expected-result comments that match the committed JSON snapshot.
