Public markets are open to anyone on Rain Trade. They're listed on the homepage, and any user can join them directly.
Who can create a public market?
Any Rain Trade user can create a public market. Public markets are ideal for broad topics like global events or sports predictions.
How are public markets resolved?
When creating a public market, the market creator can choose how the outcome will be decided:
AI Oracle: An automated system that verifies the result across multiple independent data sources. It uses a consensus-driven process — the outcome is confirmed only when the majority of its Explorer Agents agree. The AI Oracle is designed to always select one of the listed options to ensure the market resolves.
Note: an additional fee of $0.30 per outcome applies when the AI Oracle is used.Manual resolution: The market creator — or any other user — reports the final outcome themselves and closes the market. If the outcome they propose is correct, they can earn between 0.2% and 0.3% of the market volume in resolver and market closer rewards. See Platform fees for a full breakdown.
What if there's a dispute?
After the outcome is announced, a limited-time window opens for participants to file a dispute. Disputes and appeals are handled through Rain's Resolution Center and go through a two-stage process:
AI Judge: Your dispute is first reviewed by the AI Judge, who rules either in your favor or upholds the original outcome.
Appeal: If you disagree with the AI Judge's ruling, you can escalate to the human oracles. The human oracles' decision is final and binding.
