About Kapitol.ai

Kapitol.ai is an enterprise-grade intelligence platform that transforms opaque congressional financial disclosures into a structured, actionable investment signal.

The platform serves institutional investors, active retail traders, and financial analysts seeking a measurable edge by following the legally sanctioned, market-moving trades of congressional insiders who consistently outperform benchmarks.

Kapitol.ai FAQ

How is Kapitol.ai different from other services tracking congressional trades?

Kapitol.ai distinguishes itself through its proprietary scoring algorithm and curation focus. While other services may provide raw data dumps, we analyze every trade based on committee jurisdiction, trade size, and timing to score its insider signal strength. We filter out the noise and deliver only the highest-conviction trades with explanatory context, transforming data into actionable intelligence rather than an overwhelming list of transactions.

What is the typical delay between a Congress member trading and the alert?

By law, members of Congress have up to 45 days to disclose their trades. Kapitol.ai's systems monitor for these filings 24/7 and alert users the instant a high-scoring disclosure is published. Therefore, the delay is solely dependent on the politician's compliance with the STOCK Act disclosure deadline, not our platform. We provide the fastest possible alert on the publicly available information.

How do you calculate the performance metrics and win rate?

Our track record metrics are calculated based on the historical performance of the trades we have curated and scored. We track the price movement of the relevant stock after our alert, comparing it to the market at the time of disclosure. A "win" is defined as a profitable position after a specified holding period (e.g., 3 months). The averages and ratios are derived from this objective, post-alert performance analysis of our published signals.

Absolutely. All the data we provide is based on legally mandated public disclosures. The STOCK Act requires these filings to be public. Kapitol.ai simply aggregates, analyzes, and disseminates this publicly available information. You are trading on publicly disclosed data, the same information available to any member of the public, albeit delivered in a timely, analyzed format.
