# How to Create a Predict
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](https://polyranger.com/prediction-market/create).
You'll land on the creation page with two 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
Provide the following — all fields are required:
| Field | What to enter |
| --------------- | --------------------------------------------------- |
| **Title** | The name of the Event (e.g., "2026 FIFA World Cup") |
| **Description** | Context that helps traders understand the topic |
| **Tags** | Category labels for discoverability |
| **Image** | A cover image for the Event page |
### Step 2. Fill in 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
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
Click `Initialize`. You'll need to sign **two separate transactions** in your wallet —
one for the Event and one for the Predict.
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.
**2.** Find your Event in the list and click `Attach` next to it.
**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.
