About this site

The Bot Ledger is a how-to for people building trading bots on prediction markets. The material comes from two months of live testing on Polymarket, Kalshi, Predict.fun and Limitless: hundreds of strategy variants, custom models, real money, and a long list of things that did not work.

Nothing is for sale here. No signals, no bot, no course, no gated content. Exchange affiliate links may appear on hosting recommendations and are marked.

Case-study figures are scaled from logged runs so the stories read cleanly, and every page that uses them says so. Exchange facts, fees, settlement rules and dates are as observed, and each page carries the date it was true. APIs and rules change; check the exchange's own documentation before you trade.
