A Predict is a single yes/no question attached to an Event — the broader topic it belongs to. For example, an Event might be “2026 FIFA World Cup” and a Predict could be “Will Brazil win the tournament?”. To get started, click Create Predict in the navigation or go directly to polyranger.com/prediction-market/create.
Create predict entry
You’ll land on the creation page with two options:
Creation options
  • Create a new Event — launch a brand new topic and attach a Predict to it
  • Attach to an existing Event — add a new Predict to an Event you’ve already created

​
Option A — Create a new Event and Predict

​
Step 1. Fill in Event details

Event details
Provide the following — all fields are required:

​
Step 2. Fill in Predict details

Predict details
Define the specific question traders will bet on — the outcome must be clearly resolvable as YES or NO based on a publicly verifiable event.

​
Step 3. Configure Outcome Reward and Mint Share

Reward config
These two parameters control how liquidity incentives are distributed at market launch. Outcome Reward — the total USDC pool allocated to reward liquidity providers for this market. When users mint positions (YES / NO) or add liquidity, they receive a pro-rata share of this pool. Mint Share — the percentage of the Outcome Reward reserved specifically for users who mint positions during initialization. The rest goes to liquidity providers who participate after launch.
Example: Outcome Reward = 100 USDC, Mint Share = 40% → 40 USDC goes to early minters, 60 USDC is distributed to liquidity providers over time.
When you mint, you deposit USDC and receive YES / NO outcome tokens in return.

​
Step 4. Initialize

Initialize
Click Initialize. You’ll need to sign two separate transactions in your wallet — one for the Event and one for the Predict.
Transaction 1
Transaction 2
Once both are confirmed, your Event goes live and appears in your created Events list. You can attach more Predicts to it at any time.

​
Option B — Attach a Predict to an existing Event

Use this when you want to add a new question to a topic you’ve already created. 1. Click Attach to existing event on the creation page.
Attach option
2. Find your Event in the list and click Attach next to it.
Event list
3. Fill in the Predict details — same fields as in Step 2 above.

4. Click Create Predict and sign the transaction in your wallet.
Adding multiple Predicts to a single Event increases its depth and makes it more attractive to traders — more questions mean more ways to engage with the topic.
