Introduction

What is Polymarket?

Polymarket is the world's largest prediction market platform. Instead of trading stocks or crypto, you trade on the outcomes of real-world events — elections, sports, economics, and more. Each market poses a question (for example, “Will X happen by December 2026?”), and you buy shares representing either YES or NO.

Share prices range from 1¢ to 99¢ and reflect how likely the market thinks the outcome is. A YES share priced at 65¢ means the market collectively estimates a 65% chance that the event will happen. If the outcome resolves in your favor, each share pays out $1. If not, it pays $0. Your profit is the difference between what you paid and the payout.

For example, if you buy 100 YES shares at 40¢ each ($40 total) and the event happens, you receive $100 — a $60 profit. If the event doesn't happen, you lose your $40. The key is identifying outcomes the market has undervalued before they resolve.

PolyMirror is a copy-trading platform built for Polymarket. It lets you automatically mirror the trades of experienced Polymarket traders (called “leaders”) in real time, so you don't have to monitor markets or place trades yourself.

When a leader you follow makes a trade, PolyMirror checks it against your configured risk controls and, if everything passes, places the same trade on your behalf within seconds. You decide how much to trade, what risks to take, and which leaders to follow.

Key Benefit: Copy-trading lets you benefit from the research and expertise of experienced traders while learning from their strategies over time.

Key Concepts

Leader: A Polymarket trader whose wallet activity PolyMirror monitors. When you create a mirror for a leader, their future trades are evaluated against your controls and copied if they pass.
Mirror: A configuration that connects you to a specific leader. It defines how much to trade and what risk controls to apply when copying their activity. You can create multiple mirrors to follow different leaders with different settings. Manage your mirrors on the Mirrors page.
Copy Trade: When a leader makes a trade, PolyMirror can automatically place a matching trade in your account — that's a copy trade. Each copy trade is adjusted to your configured size and risk limits, so you're never trading more than you're comfortable with.
Position: When you buy shares in a market outcome, you hold a position. For example, owning 50 YES shares on “Will it rain tomorrow?” means you're positioned to profit if it rains. You can view all of your open positions on the Positions page.
