Jev Prediction Markets

A demo that has three decision models read recent news and price Polymarket and Kalshi questions, then compares their probabilities with live market odds and replays how each model changed its mind article by article.

An experiment that paper trades real Polymarket and Kalshi markets with a fake $100,000 bankroll, using TypeSafe's Jev as the judge of forecasts fed by Claude research; after about two weeks it reported being less accurate than the market's own price.

Terminal agent for Polymarket's BTC Up or Down five-minute markets. Roughly every five seconds it asks Jev whether BTC finishes UP or DOWN versus the window open, then abstains or buys once and holds to resolution. Defaults to dry-run; live orders are opt-in.
