Buying shares

- Click on the market to open the trading panel
- Select Yes or No

- Review the estimated cost and potential payout
- Click Buy to confirm
Your order is submitted to the orderbook. Market orders fill instantly at the best available price. Limit orders sit on the book until matched. Both are gasless — noma covers all transaction fees.
Heads up on minimum trade size. noma doesn’t set a minimum — but the providers that execute your trade do. Polymarket and Kalshi each enforce their own minimum order size at the orderbook level, so very small orders may be rejected by the provider even though noma accepts them. If you hit a minimum, bump the size up slightly and the order will go through.
Understanding your position
After buying, your position appears in your Portfolio:
| Field | Description |
|---|
| Shares | Number of shares you hold |
| Avg Price | Your average entry price per share |
| Current Price | The market’s current trading price |
| P&L | Your unrealized profit or loss |
Selling shares
You can sell at any time before resolution:
- Open the market where you hold a position
- Click Sell
- Enter the number of shares to sell
- Confirm the trade
If the price has moved in your favor, you lock in a profit. If you think you’re wrong, you can cut your loss early instead of waiting for resolution.
After resolution
When a market resolves:
- Winning shares automatically pay out $1.00 each to your balance
- Losing shares are worth $0.00 and are burned
Payouts are automatic — no need to redeem manually.
Order types
| Type | Behavior |
|---|
| Market | Fills immediately at the best available price |
| GTC (Good-Til-Cancelled) | Sits on the orderbook until filled or cancelled |
| GTD (Good-Til-Date) | Expires at a specified time if not filled |
Tips
Start small. Prediction markets can be volatile, especially 5-minute markets. Start with small positions while you learn how prices move.
Watch the spread. A tight spread (small gap between Yes and No prices) means more liquid markets and better fills. Wide spreads eat into your profits.
