How to Set Up a Polymarket Trading Bot (Step-by-Step)

Getting your Polymarket trading bot setup right is mostly about preparation, not code. If you get the wallet, funding, and permissions in the correct order, the actual bot install takes minutes. This guide walks through every step a beginner needs, from creating an account to running your first automated order on your own machine. Before anything else, understand the ground rule: prediction markets carry real risk, including the risk of losing your entire deposit. A bot executes faster and more consistently than you can by hand, but it does not create an edge that isn't there.

Step 1: Set up your Polymarket account and wallet

Polymarket runs on the Polygon network and settles trades in USDC. When you sign up, the platform creates a proxy wallet linked to your login. Your funds live in that wallet, not with any bot. If you are completely new to the platform, read what is Polymarket first so the mechanics of shares, prices, and resolution make sense before you automate anything.

Confirm you can legally use the platform in your region and understand the terms. Our overview of whether Polymarket is legal covers the basics, but you are responsible for your own compliance.

Step 2: Fund the account with USDC

Your bot cannot trade with money that isn't there. Deposit USDC on Polygon into your Polymarket wallet before you configure anything. Start with an amount you are fully prepared to lose, not your target trading size. A step-by-step walkthrough lives in our guide to depositing USDC on Polymarket. Send a small test deposit first, confirm it arrives, then top up.

Step 3: Generate your API credentials

A bot needs permission to read markets and place orders on your behalf. Polymarket uses API keys derived from your wallet signature for authenticated actions on its order book. When you generate these keys:

• Store them in a password manager or a local environment file, never in a shared chat or screenshot.
• Treat the private signing material like a house key. Anyone who holds it can move your funds.
• Keep the keys on the same machine that runs the bot so they never travel across the internet unnecessarily.

A genuinely self-hosted bot like POLBOT reads these keys locally and signs orders on your device, so your credentials and funds stay under your control the entire time. There is no third party holding custody.

Step 4: Install the bot on your own machine

You do not need a data center or a terminal to run a bot. A well-built self-hosted app installs like any desktop program: download, open, and paste in your keys. The difference between self-hosted and hosted setups matters for security and control, and we break it down in self-hosted vs hosted trading bots. With a self-hosted approach:

• You run the software on your own laptop or desktop.
• Your keys never leave your device.
• Nobody else can freeze, front-run, or seize your positions.

Step 5: Configure your strategy and limits

This is where most of your thinking should go. Before enabling live trades, define the rules the bot will follow:

• Position size: a fixed, small amount per trade so one bad run cannot wipe you out.
• Market selection: which events or conditions the bot is allowed to enter.
• Stop conditions: a daily loss cap that halts trading automatically.

Be realistic about the type of market you target. Very short-term "up or down" crypto markets are close to coin-flips over their time window, and without a measurable, tested edge, a bot simply loses faster. Read up or down crypto markets explained before you point a bot at them.

Step 6: Paper trade before going live

Never let real money be your first test. Run the bot in a paper or simulation mode, or with the smallest possible stake, and watch it for a meaningful stretch of real market conditions. Confirm that it enters, exits, and respects your loss caps exactly as configured. Our guide to paper trading explains how to read the results honestly rather than fooling yourself with a lucky sample.

Only after the bot behaves predictably in testing should you enable live trading, and even then with money you can afford to lose entirely.

A realistic view of what a bot does

A trading bot is a discipline tool, not a money machine. It removes emotion, reacts instantly, and follows your rules without hesitation. It does not predict the future or guarantee gains, and anyone promising fixed returns is not being honest with you. Set it up carefully, keep your keys on your own machine, size positions small, and treat every deposit as risk capital. Done that way, automation becomes a way to test ideas rigorously rather than a shortcut to profit.
