CapitolGain — Trade What Congress Trades
Live Congressional Intelligence

Everyone Shows You The Data. At CapitolGain, We Think. Meet Seylah.

CapitolGain tracks every congressional stock trade in real time — and Seylah, our AI intelligence engine, analyzes the patterns, clusters the signals, and flags the anomalies before the market catches on. And with Octavius, we bridge those signals directly to Kalshi prediction markets — surfacing positive expected-value trades before the crowd prices them in.

Not Just Another
Congress Tracker

Other platforms dump the data and leave you to figure it out. CapitolGain connects the dots — Seylah watches your portfolio, analyzes congressional patterns, and tells you what it means.
