About Kapitol.ai

Kapitol.ai solves this by monitoring every filing in real-time, scoring each trade based on the strength of its insider signal, and providing plain-English analysis. The platform filters out the noise to highlight only the highest-conviction moves from committee chairs and key members, allowing investors to follow the "smart money" in Washington.

Kapitol.ai FAQ
Is this insider trading?
No. Members of Congress are legally allowed to trade stocks based on their non-public knowledge, a loophole largely upheld by the STOCK Act which only requires disclosure. Kapitol.ai simply aggregates and analyzes these legally mandated public disclosures, giving you access to information that is already public but notoriously difficult to find and interpret.
How accurate is the track record?
The track record is based solely on publicly disclosed congressional trade data. Our reported 68% win rate and +19% average return are calculated from the 157+ trades we have curated and scored since January 2025, comparing the stock's performance against the trade disclosure date. Past performance does not guarantee future results.
What is a "Critical" signal trade?
A Critical signal is our highest score, assigned to trades that show the strongest insider conviction. These typically come from Committee Chairs or key members with direct jurisdiction over the traded company's sector, involve maximum position sizes for that politician, and occur during relevant political timing windows.
Is there really a free account?
Yes. We offer a free account that provides access to curated trade alerts and basic platform features. No credit card is required to sign up. This allows you to experience the value of the service and see actual trade previews before considering any premium upgrade.
