The retired Python bot behind a public Polymarket wallet. It market-made on Polymarket's sports markets (esports and traditional) for a few months in early 2026 and finished up about $5k net, every trade on-chain at @b00k13. This repo is the actual code, plus the analytics I built to work out why the \"guaranteed\" strategy still bled money on the parts that were meant to be safe. Most \"I built a Polymarket bot\" repos are a README and a dream. This one traded real money and leaves a public wallet you can reconcile it against. At some point it also mostly stopped being profitable, and the write-ups at the bottom are honest about why. It was built almost entirely with AI, in my spare time. That's not an excuse for the quality. You may find bugs. There are certainly things to improve. But it's still the exact bot that I used and it could be a good basis for you if you want to get into Polymarket market making. Read, learn, improve - not plug and play I'm giving this away because the code was never the hard part. The edge was fresh odds and speed , and here both are on you: - This is the retired Python version . The bot I run now is a Rust rewrite and it's not in this repo. - The scrapers aren't included. The bot reads odds from a source you supply. It ships with a the-odds-api path - a public, paid API - and the private scraping pipel","default_branch":null,"files":null,"tree":[],"storefront":"/r/kachence","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/kachence/polymm/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
