Rain.one is a decentralized prediction markets protocol built on the Arbitrum blockchain, enabling users to create, trade, and resolve custom markets on any topic—ranging from global events like elections or sports outcomes to niche, community-specific scenarios—through a permissionless, fully on-chain platform that combines AI-driven oracles for automated resolutions with decentralized human oversight for disputes without centralized gatekeepers.

Launched in beta on November 6, 2025, it introduces innovative private markets alongside public ones, allowing creators to host exclusive, tailored predictions while markets operate on USDT for liquidity and use an Automated Market Maker (AMM) for dynamic pricing based on participant conviction.

The protocol's hybrid resolution system features Delphi (multi-AI agents for data verification) and Lex (AI judge for initial rulings), with escalations to human oracles if challenged, fostering trust and efficiency in a model designed to be the "Uniswap of prediction markets."
