Any Rain Trade user can create a prediction market — either public (listed on the homepage, open to everyone) or private (invite-only with an access code). As the market creator, you earn 1% of the total trading volume. To get started, click the Create button in the top-right corner of your screen, then follow the steps below to set up and publish your market.
Step 1: Enter your market question
In the What do you want a market on? field, type your question.
Example: "Will Bitcoin close above $150,000 by end of 2026?"Not sure what to ask? Click one of the example suggestions shown below the field to get started.
Click Create.
Step 2: Review and edit your draft
Rain Trade automatically generates a market image and fills in suggested tags based on your question. It also revises your question to make it more accurate and verifiable. For example, the question "Will it rain in Amsterdam tomorrow?" might be refined to include a specific date and a clear data source. For tips on writing a strong market question, see Drafting a good market question.
Market Image: An image is generated automatically. Click Regenerate to get a new one, or Upload to use your own.
Edit question: Review the market question and adjust the wording if needed.
Tags: Edit or add tags to help users find your market.
When you're happy with the draft, click Continue.
Step 3: Choose visibility and trading mechanism
Public: Listed in the global market feed. Anyone can trade.
Private: Hidden from the public feed. Only people you share the access code with can view and trade.
Trading mechanism — choose how orders are matched:
Constant-product AMM: An always-on liquidity pool. Best for new or thin markets — any size trade is filled automatically, with slippage that scales with depth.
Central limit order book: Maker/taker matching with explicit limit prices. Better for high-volume markets with active makers — tighter spreads at scale.
Step 4: Set resolution criteria, close date, and liquidity
Fill in the following fields:
Resolution criteria: Describe exactly how the outcome will be determined. Be specific — include your source of truth and the exact resolution moment. This is the point in time the outcome will be evaluated at, even if you check and report it later. For example:
Market question: "Will it rain in Amsterdam on 12 June 2026?"
Resolution criteria: "Resolved using KNMI official weather records for Amsterdam Schiphol Airport. Rain is defined as measurable precipitation (≥0.1 mm) recorded between 00:00 and 23:59 local time on 12 June 2026."Closes at: Set the date and time when trading stops.
AMM Dust Seed: The initial liquidity you add to fund the market. The minimum is $10 USDT. For order-book markets, this is split into resting limit orders — traders need a counterparty to fill.
Step 5: Configure outcomes
Choose your Market type:
Binary: A single Yes / No question. The default for most markets.
Multi-outcome: Several sub-markets, each tradeable as a separate Yes / No.
For binary markets, set the starting Yes / No probability — each value represents that outcome's share of the market. The two values must add up to 100%. The default is 50 / 50, meaning both outcomes are considered equally likely at the start. For multi-outcome markets, each possible result is listed as a separate tradeable outcome. You can add or remove outcomes and set an initial probability for each.
Step 6: Choose a resolution method
Select how the final result will be determined once the market closes:
AI-Powered Resolution (Recommended): The AI Oracle verifies the result across multiple data sources and resolves the market automatically with full impartiality. Powered by Olympus AI.
Manual Resolution: You determine the market outcome yourself and earn the 0.1% resolver fee.
Step 7: Review and publish
The final screen shows a full summary of your market before it goes live:
