About OpenSpending
OpenSpending is an independent, data-driven site tracking federal government spending. We use USASpending.gov as our primary data source — the U.S. Treasury's official record of federal spending — to bring transparency to how $11.2 trillion in taxpayer money is spent each year. With 60+ pages of analysis, tools, and data, we cover everything from individual contractor deep dives to county-level spending breakdowns, international spending by country, product & service categories, grant recipients, and interactive tax calculators.
Our mission is simple: taxpayers fund the government, and they deserve to see exactly where that money goes — without needing a PhD in public policy to understand it.
Who Built This
OpenSpending is built by TheDataProject.ai — an AI-powered data journalism initiative focused on making public data accessible, understandable, and actionable. We use AI tools to process, analyze, and present large government datasets that would otherwise require teams of analysts to parse.

Editorial Perspective
OpenSpending takes a libertarian lens on federal spending. We believe taxpayers deserve full transparency into how their money is spent — and we're skeptical that bigger budgets automatically mean better outcomes.
We support efforts like DOGE (the Department of Government Efficiency) to bring accountability and transparency to federal spending. When budgets triple in under a decade, when ten companies capture the majority of federal contract dollars, when billions flow overseas with minimal oversight — those are stories worth telling.
We let the data speak for itself, but we don't shy from calling out waste when we see it. Our goal isn't partisan — it's accountability. The numbers don't belong to any party. They belong to you.
“Built for taxpayers who want to know where their money goes.”

Data Sources
- USASpending.gov — Our primary data source for all spending figures. We pull data via the USASpending API and bulk download files maintained by the U.S. Department of the Treasury. This includes contracts, grants, agency budgets, and individual award transactions.
- Bureau of Economic Analysis (BEA) — GDP data and economic context for spending-as-percentage-of-GDP comparisons and global benchmarking.
- U.S. Census Bureau — Population data and state-level demographics for per-capita spending calculations.
- Congressional Budget Office (CBO) — Budget projections, debt forecasts, and fiscal analysis used in our national debt and interest coverage.
- Treasury Fiscal Data — National debt, revenue, and budget execution data from the U.S. Treasury.
- GAO Report GAO-24-105833 — Government Accountability Office report on fraud and improper payments across federal programs.
Methodology
We pull data from the USASpending API and pre-process it into static JSON files for fast, reliable delivery. No server-side queries or database calls — just clean, pre-computed data served directly to your browser.
Fiscal Year 2025 runs from October 1, 2024 through September 30, 2025. Most figures reflect obligations (legally binding commitments to spend) rather than actual cash outlays, as obligations are the most current measure of spending activity.
Contractor deduplication: Many large contractors operate through subsidiaries that appear as separate entities in federal data. For example, Lockheed Martin, Sikorsky Aircraft, and Rotary Wing all roll up to the same parent company. Our deduplicated dataset merges subsidiaries under their parent company using USASpending's UEI (Unique Entity Identifier) hierarchy to give a more accurate picture of contractor concentration.
All dollar amounts are nominal (not inflation-adjusted). Rankings are based on total obligated amounts unless otherwise noted.
Open Source
OpenSpending is built with Next.js, TypeScript, and Tailwind CSS, with interactive charts powered by Recharts. The site is deployed on Vercel.
All underlying data is public and sourced from USASpending.gov. We believe government spending data should be easy to access, easy to understand, and impossible to ignore.
