The original decentralized prediction market protocol on Ethereum with permissionless market creation
Last updated: April 2026
Augur is the first decentralized prediction market protocol, launched on Ethereum in 2018 after one of the largest ICOs of its era. It pioneered the concept of permissionless market creation where anyone can create a market on any topic and REP token holders act as decentralized oracles to resolve outcomes. Augur V2 migrated settlement to DAI for price stability and redesigned the dispute and resolution system. While Augur never achieved mainstream trading volumes comparable to its whitepaper ambitions, it remains the most important academic and technical reference for decentralized prediction market design — its REP oracle system, dispute resolution mechanism, and market creation model have influenced every subsequent prediction market including Polymarket and Gnosis. Augur's open protocol allows anyone to build a trading interface on top of its contracts, and Augur Turbo created faster-settling markets for sports betting use cases. The REP token incentivizes oracle reporters to accurately resolve markets by slashing dishonest reporters. For researchers and developers in the prediction market space, Augur's extensive documentation and open-source codebase remain the canonical reference.
