There's something philosophically inconsistent happening in prediction markets right now.
Polymarket outcome shares are ERC-1155 tokens. They live on-chain. They're tradable, transferable, and they encode real probabilistic information about the world. By every definition that matters in Web3, they are financial assets.
And yet the DeFi layer treats them like they don't exist.
You can deposit ETH, wBTC, stablecoins, LSTs, RWAs, and a hundred other on-chain assets into lending protocols and put them to work. But your Polymarket positions - assets that might represent months of research, genuine information edge, and real capital conviction - sit idle until resolution. No composability. No yield. No capital efficiency. Just waiting.
This is the gap PredMart was built to close.
What PredMart does
PredMart (https://predmart.com/) is a non-custodial lending protocol on Polygon purpose-built for Polymarket outcome shares. Deposit your shares as collateral. Borrow USDC against them. Keep your position open. Your conviction stays intact while your capital gets back to work.
Lenders supply USDC to the pool and earn yield from borrower interest. The protocol operates as a two-sided marketplace with no intermediary and no custody - just smart contracts, on-chain collateral, and transparent risk parameters.
The hard part: binary collateral
Most DeFi lending assumes continuous collateral. ETH drifts. It gives liquidation engines time to respond. Prediction market shares don't drift - they resolve to exactly $0 or $1, and the path there can be violent and sudden.
Building a risk engine for binary collateral required rethinking the fundamentals:
A dynamic 7-anchor LTV curve scales borrowing limits with share price - 2% LTV at near-zero probability, 75% LTV at near-certainty. A share at 90 cents and a share at 15 cents are not the same risk and shouldn't be treated as such.
Liquidations trigger via real-time WebSocket monitoring within seconds of health factor dropping below 1.0. Block-time liquidation isn't sufficient for this collateral type.
A depth gate samples Polymarket order book liquidity hourly and caps borrowing per token at the 25th percentile of 7-day ask-side depth. If the exit capacity isn't there, the protocol doesn't let exposure grow beyond what can be liquidated.
A price drop guard blocks new borrowing during rapid crashes - defined as a 35% relative and $0.08 absolute drop within three minutes.
Why this matters for the on-chain information economy
Prediction markets are one of the most interesting primitives in crypto precisely because they turn beliefs into assets. When someone trades on Polymarket, they're putting capital behind a probabilistic claim about the world. That's not gambling - it's a financial instrument encoding information.
But information is only as good as the capital willing to back it. Right now, sophisticated traders with genuine edge are penalized by the capital lockup cost of long-duration markets. That means less informed capital in those markets, and less accurate prices.
Unlocking liquidity from positions doesn't just help individual traders - it keeps better-informed capital in the market longer, improving the signal that prediction markets are supposed to produce.
DeFi's core thesis has always been that on-chain assets should be composable and productive. Prediction market shares are on-chain assets. PredMart is the composability layer they've been missing.
