How to Open a Leveraged Position on Polymarket (Video Demo)
In this demo, we walk through how to open a leveraged position on a Polymarket market using PredMart — the non-custodial margin account for Polymarket. The whole flow is one transaction: pick a market, set your leverage with the slider, and click open.
What the demo shows
When you open a position, PredMart takes your USDC as equity, advances additional USDC from the lending pool, buys the shares on Polymarket at the market price, and records the shares as your collateral and the advance as your debt. You stay in control of the position the entire time, and you can close it whenever you want.
You can open with up to 5x leverage at any share price — PredMart applies a flat 80% LTV, so the ceiling is the same whether your shares trade at $0.20 or $0.90. In practice, most traders size around 4x to keep a buffer above their liquidation price. The slider shows the live maximum available for the market you're looking at.
How PredMart Works
PredMart adds a credit layer on top of Polymarket. Polymarket caps you at 1x exposure and locks your capital until a market resolves. PredMart changes that:
- Leverage trade — open a position with up to 5x leverage in one click.
- Borrow against shares — already holding Polymarket shares? Deposit them as collateral and borrow USDC without closing your position. Use that USDC however you want — buy more shares, top up another position, or move it off-platform.
- Lend USDC — supply idle USDC to the lending pool and earn yield paid by leverage traders and borrowers. You receive pUSDC, a vault token that grows in value as interest accrues. The yield comes entirely from real borrowing demand — no token emissions, no incentives.
Security & Trust
PredMart is fully non-custodial. Your funds sit in smart contracts on Polygon, not in any company wallet, and no team member can move them unilaterally. Your shares are held in a Gnosis Safe that you control.
The smart contracts have been audited by Hashlock, a firm with 500+ audits completed and over $4 billion in on-chain assets secured — the full report is public. The protocol is also listed on DeFiLlama and DappRadar with real, publicly verifiable TVL.
