Capitolisation

Capitolisation is a financial tracking platform that monitors stock trades disclosed by members of Congress. Elected officials in the United States are required to report their securities transactions, and this tool aggregates that data into a browsable dashboard where you can see who bought what, when, and how those positions have performed since.

The idea behind it is simple. Congressional members have access to briefings, committee meetings, and policy discussions that could inform their investment decisions. Whether or not that information gives them an edge is a matter of debate, but the trades themselves are public record. Capitolisation makes that record easy to browse without digging through government disclosure portals yourself.

The interface breaks down activity by individual member, showing 30-day returns alongside an S&P 500 benchmark so you can see how their portfolios compare to the broader market. You can also view rankings of the most purchased and most sold stocks over the last month, giving a quick snapshot of where congressional capital is flowing. If a handful of legislators are piling into the same name, you'll see it here.

It's built for investors who treat congressional trading as a signal worth watching. Some use it as a curiosity, others as part of a broader research process. The platform isn't giving advice or recommending trades. It's surfacing data that already exists in public filings and presenting it in a digestible format.

What sets it apart from other congressional stock trackers is the emphasis on performance comparison. Instead of just listing transactions, it shows how those trades have done relative to the index. That context matters if you're trying to figure out whether a particular member's track record is meaningful or just noise.

Pricing isn't listed on the homepage, and there's no mention of a paid tier, so it appears to operate as a free tool at the moment. The site includes a clear disclaimer that it displays public disclosures only and does not constitute investment advice, so treat it as a data source rather than a recommendation engine.
