What is polymarket

Last updated: April 1, 2026

Quick Answer: Polymarket is a decentralized prediction market platform where users buy and sell shares that represent different outcomes of real-world events. It operates on blockchain technology, primarily using Polygon, and allows trading on events ranging from politics and sports to cryptocurrency and weather.

Key Facts

Overview

Polymarket is a blockchain-based prediction market platform that allows users to speculate on the outcomes of real-world events. Unlike traditional betting platforms, Polymarket uses cryptocurrency and smart contracts to create decentralized markets where users can buy and sell shares representing different possible outcomes. This technology enables transparent, instantaneous settlement and 24/7 trading without intermediaries.

How It Works

Users on Polymarket select an event and choose to buy or sell shares for different outcomes. If a user believes an event will occur, they buy shares at a lower price with the goal of selling them at a higher price when the probability increases. Once an outcome is determined, correct shares are worth $1 and incorrect shares become worthless. The platform uses USDC stablecoin, which is pegged to the US dollar, to minimize volatility.

Types of Markets

Polymarket hosts markets across multiple categories:

Key Features

Polymarket operates continuously without market closing times, allowing global participation. The platform's order book system displays real-time probability estimates based on trading activity. Users can also participate in automated market maker (AMM) liquidity pools to earn fees. Polymarket maintains strong security through smart contract audits and custody solutions for user funds.

Benefits and Considerations

Prediction markets provide valuable price discovery mechanisms and aggregate crowd wisdom about future events. However, participants face financial risk, and regulatory status varies by jurisdiction. Some users are restricted from accessing Polymarket based on their location due to regulatory requirements.
