About Kapitol.ai

Members of Congress trade stocks on insider knowledge - legally. Under the STOCK Act, they must disclose every trade, but those filings are buried in government databases and nearly impossible to act on.

Kapitol.ai fixes that. We monitor all 535 Congress members, collect every filing the moment it drops, and score each trade on committee jurisdiction, position size, and political timing. Only the highest-signal moves make it to your feed, with plain-English analysis explaining exactly why it matters.

Not every congressional trade is worth your attention. Ours are scored Low, Medium, High, or Critical based on how strong the insider signal is. Critical trades come from committee chairs with direct jurisdiction and maximum position size, historically the highest-conviction calls.

Free account included. No credit card required.
