OCC will clear and settle every trade executed on IEX Options LLC under a new participant agreement announced Oct. 5, 2026, extending the central counterparty's reach to a 21st options venue just three days after the new exchange's Oct. 2 launch.

The addition marks OCC's first clearing relationship with any IEX-operated venue. It raises OCC's participant roster to 20 options exchanges, two futures exchanges, and one stock loan exchange — 23 trading platforms in total, matching the count OCC publishes in its corporate description.

What does the new venue bring to clearing members?

IEX has run an equities exchange since 2016 and reports market share above 4% of consolidated U.S. equity trading volume, with approximately 8.5% of exchange-traded volume as of Q3 2026. IEX Options is its first listed-options market.

For OCC clearing members, the addition means a new destination routed through a single CCP:

• IEX Options tape liquidity cleared alongside 19 other U.S. options venues
• Existing OCC margin and risk-management treatment applied to the new exchange
• One novation channel for both options and the two futures exchanges already on the OCC roster

What did OCC say about the tie-up?

"IEX brings a well-established track record and a different approach to options market structure," said Andrej Bolkovic, Chief Executive Officer of OCC. "We're glad to extend the same clearing and risk management standards our participants rely on every day to this new venue."

Ivan Brown, Head of Options at IEX, framed the partnership as the start of a working relationship: "We appreciate the OCC and our work together as we bring IEX Options to market. We look forward to our continued collaboration into the future."

How does this fit OCC's regulatory standing?

OCC operates as a Systemically Important Financial Market Utility (SIFMU) under the joint jurisdiction of the SEC, the CFTC, and the Board of Governors of the Federal Reserve System. Founded in 1973, OCC clears options, futures, and securities lending transactions for more than 100 clearing members.

The new participant relationship carries no disclosed rule filing or comment period; it is a contractual clearing addition rather than a rule change. No compliance deadline applies to clearing members beyond standard onboarding with the new venue.

What is the execution-workflow implication?

For buy-side and sell-side desks, a new options exchange on OCC translates into routing changes, not clearing changes. Firms already connected to OCC need no new clearing arrangement; they gain access to IEX Options through their existing clearing member and standard order-routing infrastructure. The decision point sits at the smart-order-router and broker-dealer level: which fee schedule, price-time priority, and liquidity profile justifies a new destination.

The Oct. 2 launch and Oct. 5 OCC onboarding leave the exchange roughly three days into production trading as of the announcement. The next datapoint to watch is IEX Options' first monthly volume print, which will indicate whether clearing-mandated access translates into measurable flow.
