About

XO Market positions itself around "conviction markets": permissionless Yes/No markets that anyone can create on any event. Liquidity is managed by a Liquidity-Sensitive LMSR market maker that deepens as participation grows. Resolution uses MODRA: an AI-driven first-pass resolver, with a decentralized jury layer for disputes. Data availability is provided by Celestia. The platform launched Mainnet Beta in mid-November 2025; coverage in Apr 2026 reported >$150M cumulative volume and 30k+ users. Some implementation specifics (chain layer above Celestia, on-chain fee accounting) are not yet exposed in public docs.
