DCO Explained: The License Prediction-Market Exchanges Also Need

A Designated Contract Market lists contracts and runs the trading venue where buyers and sellers meet. A Derivatives Clearing Organization does a different job entirely: it clears and settles those trades, guarantees performance between counterparties, and holds the collateral backing open positions.

The two functions are legally separate at the registration level even when the same corporate family runs both. Under Section 5b of the Commodity Exchange Act and Part 39 of the CFTC's regulations, any entity providing clearing services for futures, options on futures, or swaps must register with the CFTC as a DCO, filing Form DCO through the CFTC Portal along with exhibits demonstrating it can meet the applicable core principles.

Section 5b's core principles cover adequate financial, operational, and managerial resources, standards for who and what can participate, risk management capable of handling stressed conditions, the ability to complete settlement on a timely basis, safeguards for participant funds, and avoiding rules that impose unreasonable restraints on competition. Core Principle O adds a governance requirement: a DCO's arrangements must be transparent and account for the views of its own owners and participants, not just its operator.

None of this is optional paperwork. It is the same statutory bar a traditional futures clearinghouse like CME Clearing has to meet, applied here to firms whose underlying product is an event contract rather than a commodity future.

Kalshi Klear LLC received its DCO Order of Registration from the CFTC on August 29, 2024, becoming the industry's 18th registered DCO; Kalshi had previously routed clearing through LedgerX, doing business as MIAX Derivatives Exchange, before bringing the function in-house. QC Clearing LLC, later rebranded Polymarket Clearing after Polymarket's 2025 acquisition of its affiliated exchange QCX, received its own DCO registration on December 17, 2024, becoming the 19th.

Both operate on a fully collateralized model: every contract must be paid for in full when a position opens, rather than backed by a smaller margin payment topped up later. That design choice removes the need to calculate variation margin or maintain a mutualized default fund, which is a large part of why the CFTC could approve these DCOs on a comparatively fast timeline. It is also not permanent by default, since Kalshi Klear's pending September 2026 filing to allow margin trading for institutional participants shows an operator can ask to move off full collateralization once it has a registered DCO to amend.

Operators have reached DCO status the same three ways they reach DCM status. Kalshi built Klear from scratch, filing its own DCO application years after its original DCM designation. Polymarket instead acquired an already-registered DCO, QC Clearing, in the same $112 million transaction that gave it QCX's DCM designation, converting what would have been a multi-year filing into a single acquisition.

A third path is simpler still: not registering a DCO at all, and instead routing trades to an existing one. Kalshi itself took this route early on, clearing through LedgerX's MIAXdx before Klear existed, the same model smaller or newer exchanges can still use rather than clearing their own trades.

Asking whether an operator is "licensed" is really at least two separate questions: whether it holds a DCM designation to list contracts, and whether it holds, or has access to, a DCO registration to clear them. A DCM with no clearing arrangement has no way to actually settle a trade, which is why every operator's regulatory footprint has to account for both registrations rather than treating the DCM as the whole picture.

It also means an operator's clearing arrangement can change independently of its trading venue. An exchange that starts out routing to a third party's DCO, the way Kalshi once did through LedgerX, can later bring that function in-house without needing a new DCM designation at all, and a DCO's own rule changes, like Kalshi Klear's margin proposal, can reshape what an already-designated exchange is able to offer without touching the DCM registration itself.
