About carbonthat

Everything here is built from public records. Nothing is scraped from a competitor, bought from a data vendor, or estimated where a filing could be read instead.

• Periodic Transaction Reports — the filings the STOCK Act requires within 45 days of a trade. House reports come from the Clerk of the House, Senate reports from the Senate's Electronic Financial Disclosure system.
• Annual financial disclosures — the year-end statements listing what a member holds, which is how a position that was never traded still shows up.
• Committee assignments — so a semiconductor purchase by someone who oversees the industry reads differently from the same purchase by someone who does not.
• Roll call votes — every recorded vote, matched to the member who cast it.
• Daily closing prices — historical market data, used for every figure the simulator produces.

• Read the disclosure feed — every tracked filing, newest first.
• Open any member and see their trades, their holdings, their committees and their votes on one page.
• Browse by committee or by state.
• Ask what following a filing would have done, on the simulator.

carbonthat is not affiliated with the United States Congress, the Clerk of the House, the Secretary of the Senate, or any government body. It is not a broker, and it is not investment advice.

A disclosure is a record that something happened, filed up to 45 days after it happened. It is not a signal, and this site does not treat it as one. The disclaimer sets out the limits of every number here, and is worth reading before you draw a conclusion from one.

Reading a filing is a parsing problem, and parsing problems have errors. Matching a name on a PDF to a sitting member is a matching problem, and those have errors too. If something here is wrong, we would rather know: tell us.
