Derivatives Clearing Organization (DCO)

Clearing is the least visible and most important part of a derivatives market. The DCO novates each trade, becoming buyer to every seller and seller to every buyer, so no participant carries the risk that the person on the other side fails to pay. It collects margin, marks positions daily and maintains a default waterfall of resources to absorb a member failure. Because it concentrates risk deliberately, it is regulated to core principles covering financial resources, risk management, settlement and system safeguards.

For prediction markets the DCO is where the structural difference from a sportsbook is sharpest. A bettor with a winning sportsbook wager is an unsecured creditor of that operator, protected only by whatever player-funds segregation the licence imposes. A participant holding a cleared event contract has a claim against a clearing house with regulated capital and a default fund behind it. The exchanges make this argument often and it is a real one. The counter-argument, which state regulators press, is that clearing solves counterparty risk while saying nothing about problem gambling, age verification or self-exclusion, which are the harms gambling regulation is actually built around.
