Transparency is core to our mission. Every data point on Disclosed Capitol originates from official government sources or established financial data providers. Here is a complete list of where our data comes from.
For details on how we process and analyze this data, see our Methodology.
Official portal for Senate financial disclosures including Periodic Transaction Reports (PTRs) and Annual Financial Disclosures (AFDs). All Senate stock trades, assets, liabilities, and income are filed here under the STOCK Act.
The House Clerk's office maintains financial disclosure filings for all House members. Many filings are submitted as scanned PDFs, which we process using AI-powered OCR to extract structured trade data.
The Securities and Exchange Commission's Electronic Data Gathering, Analysis, and Retrieval system. We pull corporate insider trades (Form 4), institutional investor holdings (13F), and activist investor filings (13D) to compare against congressional trading patterns.
Official source for legislation data. We track bills sponsored and cosponsored by each member of Congress and cross-reference with their trading activity to detect potential trade-legislation overlaps.
Campaign finance records including individual and PAC contributions to congressional campaigns. We use this data to analyze donor-to-trade connections and lobbying relationships.
The official source for federal spending data. We track government contract awards and cross-reference with politician committee assignments and trading activity to surface potential conflicts of interest.
Lobbying registration and activity reports filed under the Lobbying Disclosure Act. We track which companies and organizations are lobbying Congress, how much they spend, and which issues they lobby on.
The Federal Reserve Bank of St. Louis maintains hundreds of thousands of economic time series. We use FRED data for macro indicators, interest rates, and economic context that may influence congressional trading behavior.
We use Yahoo Finance as our primary source for historical and current stock prices, company information, sector classifications, and dividend data. This powers our return calculations, portfolio valuations, and performance metrics.
While we strive for accuracy, government filings are self-reported and may contain errors or omissions. Price data may be delayed or unavailable for delisted securities. Our OCR pipeline for scanned PDFs achieves high accuracy but is not perfect. If you spot an error, please let us know.
