How Augur Works

Augur is a decentralized oracle and prediction market platform. Users feed real world information into Augur's contracts. Augur ensures the accuracy of this real world information by providing a financial incentive for REP token holders to correct markets they believe have been reported on incorrectly. There are several ways users can participate in Augur: you can trade shares in markets, create prediction markets, or participate in the reporting system to keep the Augur oracle honest.

Markets & Trading

On Augur, market creators set the event start and end times, a designated reporter, resolution source, and settlement fee. Traders can purchase shares in Augur markets immediately after market creation. The Augur contracts maintain an order book for every market created, and offer shares at the current best price. Settlement fees are paid by traders when positions are settled within a market. After the event has occurred, the outcome is determined by the designed reporter, or ultimately, Augur’s decentralized oracle, if necessary.


REP (Reputation) token holders can participate in the Augur reporting system. REP token holders have the ability to dispute the tentative outcome of any Augur market within 7 days of resolution by staking a dispute bond. When doing so, the Augur market will go into a dispute round, where REP holders can stake REP tokens on one of the markets possible outcomes. If the tentative outcome is overturned, users who participated by staking on the new winning outcome will receive a 50% ROI. There is always a financial incentive to keep the Augur oracle reflecting reality.
