PredMart — Bigger Positions on Prediction Markets
PredMart lets you open a bigger position on a prediction-market outcome than your cash alone allows. Pick an outcome you believe in — Yes or No on a market, or a specific team, candidate, or option — put down some money (your margin), and PredMart lets you take a position up to 5x times bigger. If your outcome wins, you make more. If it loses, you can lose your margin. A shared pool funds these trades — you can also put money into the pool and earn a share of the fees.
In short
Prediction markets let you trade on real-world events, but typically cap you at 1x exposure. PredMart adds leverage: put down USDC as margin straight from your wallet, pick Yes or No (or a specific outcome), and the pool takes the other side. When you close or the market resolves, your profit or loss settles in USDC back to your wallet.
Who is PredMart for?
| Role | What you do | What you get |
|---|---|---|
| Traders | Put down USDC margin straight from your wallet, back Yes or No on any market at up to 5x leverage | Bigger exposure to prediction market outcomes |
| Liquidity Providers (LPs) | Deposit USDC into the shared pool | Earn a share of the trading fees as the counterparty |
How it works
-
Open a position — Choose a market, pick Yes or No (or whichever outcome you believe in), set your leverage (up to 5x). PredMart uses the current fair price, you confirm, and the trade is recorded on-chain. An entry fee of 0.1% of the total position size is deducted from your margin.
-
Hold — Your position tracks the fair price of the outcome you picked (a manipulation-resistant price refreshed every 30 seconds). A small holding fee accrues while open. You can add margin, reduce size, or close any time.
-
Close or settle — Close any time to lock in your profit or loss, or wait for the market to resolve. A profit fee of 10% applies if you made money (7% goes to LPs, 3% to the protocol). If your margin drops to the maintenance level (15%), the position is closed automatically and you lose the margin left in it.
See How Positions Work for the full lifecycle and Margin and Liquidation for liquidation details.
Providing liquidity
LPs deposit USDC into a shared pool and receive pool shares representing their stake. The pool backs all trader positions as the counterparty:
- Earn fees — Entry, profit, and holding fees from traders flow to the pool.
- Bear counterparty risk — If traders profit, the pool pays out; if traders lose, the pool gains.
- Per-market cap — Exposure to any single market is capped at 10% of pool assets to limit concentration.
LP value fluctuates as positions open, close, and settle. LPs can withdraw their money at any time. See Providing Liquidity for deposit/withdraw details and risk factors.

Security
- Your money stays in the smart contract — The PredMart team cannot take it, move it, or freeze it.
- Bounded operator — One system signs prices and submits transactions. It cannot drain the pool, upgrade contracts, change settings, or close a healthy position.
- Emergency pause — The protocol can be paused to halt new positions if needed.
To open, close, or settle a trade, you go through PredMart's system. Depositing and withdrawing from the pool are the only actions that run without PredMart involvement.
