Problem Statement
Prediction markets today are limited to high-profile events curated by centralized platforms. The long tail — niche, specific questions about the future — has no market because the overhead of creating, matching, and resolving individual bets is too high. A single bet about whether your city council will approve a transit plan, or whether a specific GitHub repo will hit 1k stars, isn't worth the operational cost for a traditional platform. Longtail uses AI agents to eliminate that overhead: one agent structures the prediction, another deploys the escrow contract, and a third resolves the outcome via an LLM jury. This makes it viable to create a market for any verifiable yes/no question at any stake size.
Longtail is an agent-powered P2P prediction market on Base. Three AI agents coordinate via OpenServ to structure predictions, deploy escrow contracts, and resolve outcomes using an LLM jury with UMA Oracle fallback. Users create yes/no predictions about any verifiable event, stake USDC, and get matched on-chain — no house edge, no intermediary, no curator deciding which markets exist. Agents do the work humans shouldn't have to.
