Building a Polymarket Trading Bot: A Comprehensive Guide

#polymarket #tradingbot #blockchain #automatedtrading

Introduction

Prediction markets like Polymarket are exploding in 2026, especially around crypto events, elections, and real-world outcomes. Manual trading works for a while, but if you want to scale, remove emotion, and run 24/7, a trading bot is the way to go.

In this post, I'm recapping AdelanX's recent live build of a Polymarket trading bot. The video is a raw, real-time recording of the setup and live account performance. Whether you're a developer looking to replicate it or a trader wanting automation, this is a great starting point.

Watch the video here: How To Build A Polymarket Trading Bot (Adelan Supports You)

Why Build a Polymarket Trading Bot?

  • Speed & Emotionless Execution — Bots react instantly to order book changes.
  • 24/7 Operation — Markets never sleep.
  • Backtesting & Strategy Testing — Iterate without risking capital manually.
  • Copy-Trading / Signal Automation — Mirror proven wallets or run your own alpha.
  • Scalability — Handle multiple markets simultaneously.

Polymarket uses a Central Limit Order Book (CLOB) on Polygon, making it programmable with standard crypto tools.

High-Level Architecture (Based on the Live Build)

From the video and common patterns in Polymarket bots:

  1. Wallet & Funding Setup

    • Polygon wallet (MetaMask or similar).
    • Deposit USDC.e → wrap to collateral (pUSD) via Polymarket's on-ramp.
    • Generate API credentials (key, secret, passphrase).

  2. API Connection

    • Use the official py-clob-client or similar SDK.
    • Connect to CLOB endpoints for markets, order books, and WebSocket streams.

  3. Data Layer

    • Fetch live markets (Gamma API or CLOB).
    • Monitor order books, prices, liquidity, and volume.
    • Pull external signals (e.g., BTC price feeds for "BTC Up/Down" markets).

  4. Signal/Strategy Engine

    • Simple directional logic (e.g., buy YES/NO based on thresholds).
    • Advanced options: momentum, mean-reversion, arbitrage, or copy-trading leaders.
    • Risk rules: position sizing, daily loss caps, slippage tolerance.

  5. Execution Layer

    • Build & sign orders (EIP-712).
    • Place limit/market orders.
    • Monitor fills, cancel/replace as needed.

  6. Monitoring & Safety

    • Logging, alerts (Telegram/Discord).
    • Dry-run mode first.
    • Kill switches and bankroll controls.

If you're building for your own business or strategy, reaching out to specialists like AdelanX can save weeks of debugging.

Quick Start Code Skeleton (Python) 

# requirements: py-clob-client python-dotenv web3

from py_clob_client.client import ClobClient
from dotenv import load_dotenv
import os

load_dotenv()

client = ClobClient(
    host="https://clob.polymarket.com",
    key=os.getenv("PRIVATE_KEY"),
    chain_id=137,  # Polygon
)

# Example: Get markets
markets = client.get_markets()
print(markets)

# Place a sample order (use with extreme caution!)
# order = client.create_order(...)
Enter fullscreen mode Exit fullscreen mode

Expand this with your signal logic, risk checks, and a main loop/scheduler (e.g., cron or APScheduler).

Pro Tip: Always start in dry-run mode and test with tiny sizes!
