Have a hunch about the outcome of a real-world event? Polymarket lets you turn insights into actual predictions — from who’ll win the next election to where crypto prices are headed or even pop culture. But what is Polymarket? By the end of this guide, you’ll understand exactly how the decentralized platform works, what makes it popular, and how it differs from other prediction markets in 2024.

What is Polymarket?

Polymarket is a prediction market ecosystem that allows users to forecast the outcomes of real-world events by buying and selling shares.

Built on the Polygon network, Polymarket lets users participate in a range of events, from political predictions and crypto price trends to pop culture and global happenings.

The platform operates without a central “house” or set odds — prices are based purely on user sentiment and supply and demand within each market.

How does Polymarket work?

Polymarket functions as a marketplace where users can trade shares based on the likelihood of specific outcomes. Here’s a breakdown of how it works:

1. User-driven odds: Unlike traditional betting platforms, Polymarket doesn’t set odds. Instead, the price of shares — ranging from $0.01 to $1.00 — reflects the market’s collective sentiment. For example, if “Yes” shares on a political outcome are trading at $0.70, it suggests a 70% likelihood of that event occurring based on user consensus.
2. Event categories: Polymarket offers a wide variety of markets, including political predictions, crypto predictions, sports, and even entertainment events. Users can participate across these Polymarket prediction categories based on their interests.
3. Market resolution: After the event concludes, Polymarket uses decentralized oracles to confirm the outcome. Correct predictions are paid out at $1.00 per share, while incorrect ones lose their value.
4. Decentralized infrastructure: Built on Polygon, the platform uses USDC to facilitate secure and low-fee transactions, making it an accessible choice for those looking to explore blockchain technology without the high fees typical of other platforms.

How does this prediction market make money?

Polymarket doesn’t operate like a traditional betting platform, where the “house” takes a cut on every transaction. Instead, it has a few revenue sources tied to platform activity:

• Transaction fees: This prediction ecosystem charges a small fee on winning trades, which goes toward operational costs and rewards for liquidity providers. This setup keeps fees relatively low compared to centralized platforms.

Yes, Polymarket is considered safe, so long as users secure their crypto wallets and follow market updates closely. The platform’s use of oracles and its user-driven model provides transparency, as outcomes are verified through a decentralized network.
