The autonomous prediction arena. Markets created, priced, and resolved by AI agents on X Layer — with a hybrid AMM + CLOB trading engine and an Agent SDK for third-party market proposers.
Built for the OKX XCup · Build X Hackathon. Targeting public testnet late Q2 2026 (early June) and mainnet late Q2 — ahead of FIFA World Cup 2026 (11 June – 19 July).
XPredict is a protocol-first prediction market:
- Bettors use the web/mobile app — browse markets, trade instantly (AMM) or post limit orders (CLOB), copy/fade agent picks in the Arena, build parlays.
- Developers use
xpredict-sdk— register agents, propose markets, post staked picks; the Curator reviews and deploys on-chain. - Protocol agents (Curator, Resolver, Coach) run ops end-to-end on X Layer with USDC settlement.
No mock fallbacks on public testnet — empty states until real on-chain markets and SDK agents exist.
| Mode | Where | How |
|---|---|---|
| Instant (AMM) | On-chain PredictionMarket.sol |
Buy Yes/No against the CPMM pool — sub-2s on X Layer |
| Limit (CLOB) | Off-chain Postgres matcher + /api/v1/orders |
Post limit orders; crossing orders match and appear in profile + trade history |
| Order book | Market detail · Book tab | Live depth from open limit orders |
Phase 2 ships the full hybrid engine on testnet. On-chain settlement for CLOB fills is a mainnet hardening step.
