Kapitol.ai

Comprehensive Congress Monitoring

Kapitol.ai's system automatically monitors all 535 members of the U.S. House and Senate around the clock. It scans official government databases to capture every new financial disclosure filing the instant it is published. This ensures no trade by any sitting politician is missed, providing a complete and real-time view of congressional trading activity as the data becomes publicly available.

Proprietary Insider Signal Scoring

Not every congressional trade carries meaningful insight. Kapitol.ai analyzes each transaction and assigns a signal score: Low, Medium, High, or Critical. This score is based on a rigorous assessment of key factors including the politician's committee jurisdiction over the traded company's sector, the size of the position, and the timing relative to legislative events. This filtering separates routine trades from high-conviction insider moves.

Plain-English Trade Analysis & Alerts

Users are not presented with raw, confusing government filings. Instead, each high-scoring trade is accompanied by straightforward, contextual analysis that explains the "why" behind the move. When a trade with a High or Critical signal is identified, subscribers receive an immediate email alert, delivering the intelligence directly to their inbox without requiring them to constantly check the platform.

Verified Performance Tracking

The platform provides transparent, data-backed metrics on the historical performance of the trades it curates. This includes the overall win rate, average returns after specific holding periods, and the average gain on winners versus loss on losers. This track record, built on publicly disclosed data, allows users to evaluate the system's efficacy and the historical edge provided by following these congressional signals.

About Kapitol.ai

Kapitol.ai is a financial intelligence platform designed to level the playing field for individual investors. It operates on a fundamental premise: members of the U.S. Congress legally trade stocks using non-public information gained from their committee work and legislative insight, and they consistently outperform the market. The problem is that while these trades are required to be disclosed by law under the STOCK Act, the filings are buried in obscure government databases, are difficult to interpret, and are not timely. Kapitol.ai solves this by acting as a dedicated monitor, analyst, and alert system. The platform tracks all 535 members of Congress, collects every trade filing the moment it becomes public, and applies a proprietary scoring system to filter out the noise. Each trade is scored as Low, Medium, High, or Critical based on factors like the politician's committee jurisdiction, the trade's size, and political timing. Users receive clear, plain-English analysis on only the highest-signal trades, explaining why the move matters. This service is for retail investors, traders, and anyone interested in following "smart money" who wants actionable, data-driven insights derived from congressional trading activity, all starting with a free account.
