The Problem

Prediction markets have reached real size, and the first credit against their positions has started to appear. That demand is validated. What serves it is not: each application decides internally which markets it supports, how much credit it offers, and how unhealthy collateral is liquidated. Capital remains fragmented behind closed risk systems. There is still no shared standard an outside lender could underwrite against, no common liquidation venue built for how these assets actually behave, and no way to compare or move outcome exposure between systems.

The infrastructure arrived fragmented

This is unusual. Every comparable on-chain asset class picked up the same open apparatus within months of reaching scale: lending markets, money-market yield, a metadata standard, liquidation venues. Spot tokens did. Staked assets did. Liquidity positions did. Event contracts got fragments instead: every protocol rebuilds underwriting, market selection, and default management privately, and none of it composes.

Consider two positions both trading at $0.70: a liquid macroeconomic contract with six months to run, and a sports contract in its final minutes. The price is identical. The collateral quality is not, and they should not support the same amount of credit. A system that cannot tell them apart cannot underwrite either, and a system that keeps the distinction proprietary cannot become a standard.

So the question is not when a common system will arrive on its own. It is why it has not, and the answer is in the collateral itself.

Why the collateral resists it

Overcollateralized lending rests on a few quiet assumptions: that prices move in steps small enough to react to, that you can sell into the market when you need to, that the borrower does not know more than you about the collateral, and that a position retains some value if things go wrong. Event positions break all four.

A position is bounded between 0 and 1 and reprices in jumps, not drifts. The same news that moves the price also drains the order book, so depth disappears at exactly the moment a lender would need it. The borrower most motivated to lever a specific outcome is often the one with the best read on it. And the contract terminates in a binary payoff, so collateral that looked sound at noon can be worth nothing by close, with no recovery path.

Bolt a generic lending market onto collateral like this and you do not get a credit market. You get an insolvency mechanism with extra steps. The four properties, and the design they force instead, are covered in Why event collateral is different.
