XO Market is a permissionless conviction marketplace where anyone can turn their beliefs into tradable Yes/No markets in real time. Built on a sovereign rollup secured by Celestia’s data availability layer, it lets users instantly create new markets with custom tokens, fees, and resolution rules. To support even niche predictions, XO Market uses an adaptive liquidity AMM inspired by LS‑LMSR, so creators can start with minimal capital and grow depth organically. Market outcomes are resolved by AI‑first oracles sourcing trusted data, while decentralized arbitration with quadratic voting by staked token holders ensures fairness in disputes.
