Augur is a decentralized prediction market protocol with its own oracle infrastructure, while Rain offers permissionless prediction and options markets accessible to anyone. The key difference is Augur’s focus on a specialized oracle system versus Rain’s broader, permissionless design. Augur suits users who prioritize trustless settlement via its native oracle, whereas Rain is better for those seeking easy entry to prediction markets and options without KYC or gatekeeping.

Augur is a decentralized prediction market and oracle protocol on Ethereum that lets users trade on event outcomes and brings real-world results onchain via economic incentives. After a 2025 revival by the Lituus Foundation, it now includes a new prediction market system and Augur Lituus, a generalized oracle for other applications.
Rain is a decentralized options and prediction market protocol built on Arbitrum, enabling anyone to create and trade custom markets with full on-chain transparency. It uses Olympus AI for market resolution and features a deflationary token model where trading fees buy and burn $RAIN. The protocol is governed by a DAO and aims to provide a permissionless, trustless platform for prediction and options trading.
