What this page does and does not contain

Period covered: filings from 2025-01-01 to 2026-10-22. Everything Congress has filed since we began keeping the record, not a rolling window.

This is what we could read from the filings, not everything Congress filed. Assets without a ticker symbol — mutual funds, bonds, real estate and private funds — are now extracted and appear under Asset classes, though they cannot be grouped by symbol the way listed equities can. Some filings still use a layout our parser cannot read. Separately, some members file on paper: the Clerk publishes those as scans with no text layer, so there is nothing in them for any parser to read. Those are counted on their own below rather than blamed on our parser, and the original is always linked. Every filing links to the original document; where we could not read one, we say so and link it anyway. A member showing no trades here has not necessarily reported none.

Filer names are reproduced exactly as the House Clerk and Senate Electronic Financial Disclosure systems label them. Senate EFD accepts periodic transaction reports from sitting senators, Senate candidates and senior staff, so a filer listed here is not necessarily a sitting member of Congress. Follow the filing link to see the original.

Congress reports each transaction as a RANGE, not an exact figure. Totals are therefore the sum of the low ends and the sum of the high ends — a true total sits somewhere between, and a single large band can dominate a column.

1496 of 12091 transactions are assets with no ticker symbol.

119 of 1080 filings here are scanned paper documents with no text layer. We report that they exist and link them; we cannot extract their rows.

Transactions

Newest first, and every column sorts. Each row links to the filing it came from. A ticker page backed by the archive can span years, so this is a table rather than a list — the questions it has to answer are "who bought the most" and "who was slowest to disclose", and neither is readable down a bulleted feed.
