About Kapitol.ai

Kapitol.ai is your high-speed, high-signal intelligence platform for tracking the stock market moves of the U.S. Congress.

Kapitol.ai fixes that with relentless efficiency. The platform monitors all 535 members of Congress 24/7, instantly collecting every trade filing the moment it's published. It doesn't just dump data on you. Each trade is rigorously scored (Low, Medium, High, or Critical) based on committee jurisdiction, position size, and political timing. You get only the highest-conviction moves in a clean feed, complete with plain-English analysis that explains exactly why the trade matters. Designed for active traders and investors who move fast, Kapitol.ai delivers a proven edge by letting you follow the legally-sanctioned "smart money" in Washington, turning opaque public records into clear, actionable investment signals.

Kapitol.ai FAQ

Absolutely. The trades disclosed by members of Congress under the STOCK Act are public information. Kapitol.ai simply aggregates, analyzes, and speeds up access to this legally mandated data. You are trading on publicly available information, just with a significant efficiency advantage.

How fast are trade alerts delivered?

We deliver alerts with lightning speed. Our systems detect new filings immediately upon publication from government sources. High-scoring trades trigger instant email notifications, ensuring you get the signal often before the broader market has digested the news.

What makes a trade "Critical" versus "High" signal?

A Critical signal is our highest conviction alert. It typically involves a committee chair or ranking member with direct jurisdiction over a company's sector, executing a maximum-sized trade (often at the $1M+ reporting threshold). These are the rarest and historically most predictive moves we track.

Do you guarantee profits based on these trades?

No. Kapitol.ai provides intelligence and analysis, not financial advice or guarantees. While the tracked data shows a strong historical performance, past results do not guarantee future outcomes. We equip you with superior information; you must make your own investment decisions and manage your risk.
