# Omen — Decentralized Prediction Markets > Omen is a fully on-chain binary prediction market platform built on Binance Smart Chain (BSC). Users trade YES/NO shares on real-world events using a Central Limit Order Book (CLOB) model, similar to professional financial exchanges. ## What is Omen? Omen lets anyone create or trade on prediction markets — questions about future events with binary (YES/NO) outcomes. Prices reflect the crowd's implied probability for each outcome (0–100%). Markets resolve when the outcome is known, and correct-side holders receive a payout. ## Key Features - **CLOB Trading**: Professional central limit order book with limit and market orders - **Low Fees**: Settlement fees charged only on profits - **Instant Settlement**: On-chain resolution with automatic payouts - **Multiple Asset Types**: Supports BNB, stablecoins, and meme tokens as collateral - **Leaderboard & Rewards**: MP (Market Points) system rewarding accurate predictions and liquidity provision - **Referral Program**: Invite friends and earn a share of their trading fees ## How It Works 1.
