Descriptions:
This Alphastack tutorial walks through building a fully functional AI-powered trading bot for Polymarket, the on-chain prediction market platform. The architecture breaks into three layers: an intelligence layer, an execution layer, and a wallet — each handled by distinct APIs that the bot orchestrates on a 15-minute cycle.
The intelligence layer is provided by the “Truth Machine,” a proprietary system that queries 21 data sources using Google Gemini to generate probability estimates and flag edge opportunities. For example, if a market prices a Gemini 3.5 release at 23% probability but the Truth Machine estimates it lower, the bot identifies the gap as an actionable arbitrage. The bot filters signals against a configurable minimum edge threshold before taking any action.
Execution relies on two Polymarket APIs: the Gamma API to monitor existing positions and market state, and the CLOB (Central Limit Order Book) API to place and cancel orders. A fill-or-kill strategy prevents stale bids from accumulating on the order book. A key design choice is that the entire system runs from a browser via Netlify serverless functions, removing the need for a dedicated server. A downloadable template document containing the full architecture overview and reusable code snippets is provided to help viewers replicate the build.
