Why this series exists
Most Polymarket bot content lives in one-shot Medium posts and thin GitHub READMEs. None of them takes a builder from "I want a bot" to "I have a bot trading my real money safely" in a single coherent path. This 32-chapter series does. We have built and run our own production trader through 2026; every chapter is grounded in code we have actually shipped, bugs we have actually hit, and postmortems we have actually written.
The series targets builders with intermediate Python or Node.js skill. It does not require web3 or trading expertise - we cover the prerequisites in chapter 2.
How to read the series
If you are starting from zero, read in order - especially Phase 1 (foundations) and Phase 2 (infrastructure). If you already have a paper-trading bot and are looking for a specific strategy or market type, jump straight to Phase 5 (strategy patterns) or Phase 6 (per-market deep dives).
Read in this order if you are new: Chapter 1 (reality check) → Chapter 2 (prerequisites) → Chapter 3 (stack) → Chapter 4 (VPS) → Chapter 29 (paper trading) → pick a strategy chapter → pick a market chapter → Chapter 30 (risk) → Chapter 31 (going live).
A 32-chapter series by Harley Young covering everything to build a Polymarket trading bot in 2026: stack choice (Python/Rust/Node), VPS hosting, the CLOB and gamma APIs, order execution, 8 strategy patterns, deep dives on every market type, paper trading, going live, and real postmortems from production.
What programming language does the series use?
Python is the primary language (py-clob-client 0.34.6 V2-compatible). Code samples also in Rust (against the V2 REST API using ethers-rs) and Node.js (@polymarket/clob-client-v2 v1.0.2). Each code-heavy chapter has tabs for all three languages.
Is the series free?
Yes. Every chapter is free to read on Polymarkets.co.il. We may include affiliate links to VPS hosts (TradingVPS is our recommended host, full disclosure) but the educational content is free.
Where do I start?
Chapter 1: "Should You Build a Polymarket Bot? Reality Check" - it sets honest expectations on profitability, time commitment, and capital. After that, follow the chapters in order, or jump to a specific phase if you have specific questions.
Will the series cover Polymarket V2 / pUSD?
Yes. The series is written for the post-April 2026 Polymarket V2 platform, including the pUSD collateral migration. All code samples target V2-native SDKs.
How long does it take to read?
Each chapter is 2,500 to 4,500 words (12-15 minute read). The full series is ~115,000 words - reading it cover-to-cover would take ~7 hours. Most builders skim the early chapters and deep-dive the strategy/market chapters relevant to their bot.
