How Decentralized Prediction Markets Work

Decentralized prediction markets use blockchain technology and smart contracts to automate event outcome betting. Users buy tokens representing different outcomes, with token prices reflecting the probability of each outcome. When an event concludes, holders of the winning tokens receive payouts, which can be fixed (simple binary outcomes) or variable (pari-mutuel pools). Oracles provide the crucial link between real-world events and blockchain smart contracts, ensuring accurate and transparent outcome verification.

Most platforms employ Automated Market Makers (AMMs) to maintain liquidity and enable continuous trading. This mechanism ensures fair pricing but can be subject to slippage and fluctuating transaction fees, depending on blockchain congestion and pool size.
