What is the best Congress stock trades tracker?

By Daniel, The Philosopher Investor · updated September 5, 2026 · every tool named is one we have used or read closely; no prices quoted because they move

Capitol Trades is the best free site to research politician trading across both chambers. Quiver Quantitative is the deepest data library, with backtests and an API. Unusual Whales folds Congress trades into its flow desk. The Philosopher Investor reads the House filings per stock, next to the options flow, the insiders and the chart, for traders who want to know what a filing means for a name they hold.

Common questions

How fast do Congress trades become public?
Members have 45 days after a trade to file under the STOCK Act, and many use most of it. The disclosure date is when the public learned of the trade; the trade date is when it happened. No tracker is faster than the filing.
Are the amounts exact?
No. Members file ranges, $1,001 to $15,000 and so on. A tracker that shows a precise total is summing bracket floors or midpoints; the honest number is an 'at least'.
Can I copy Congress trades?
You can follow them, with the lag in mind. Some members' records after their filings are strong, most are ordinary. Treat a filing as one witness on a name, and check it against the chart and the flow before acting.
Which trackers are free?
Capitol Trades is free. Quiver has a free tier. This desk publishes a free daily Congress page and free per-stock Congress pages; the cross-reads and the member records are part of the paid desk.
