With $512 billion on the line, these 200 companies dominated

Bloomberg Government presents the seventh annual BGOV200—a ranking of the top 200 federal contractors based on prime contracts awarded in fiscal 2017. The report finds 92 companies improved their ranking from fiscal 2016 to fiscal 2017, while the same number, 92 companies, fell in the rankings. Sixteen companies, including those ranked No. 1 through No. 6, held the same positions as last year, while 26 companies entered the BGOV200 list this year. The share of total government obligations won by the top 200 was 64 percent, or $327 billion of $512 billion, which is about the same share of spending obligations won by BGOV200 companies in fiscal 2016.

Explore how—and with what companies—the U.S. Government spent more than $512 billion last fiscal year. Scroll through the list, share company rankings and download the full report for detailed analysis of every company.
