On September 22, 2026, Kalshi Klear LLC submitted a request to the CFTC for approval of a new initial margin methodology for eligible event contracts.
Under the proposal, qualifying event contracts would no longer need to remain fully collateralized at all times. Instead, Kalshi Klear would apply risk-based, side-specific initial margin to eligible YES and NO positions based on modeled adverse price movements. The framework would apply only to contracts meeting product- and side-specific eligibility criteria; sporting-event contracts are excluded from margined treatment under the filing.
Key Features
The framework targets a confidence level above the CFTC’s 99% requirement and proposes a one-day margin period of risk, subject to CFTC approval. It also includes volatility floors, scheduled-event add-ons, liquidity and concentration charges, restrictions on portfolio offsets, and increasing collateral requirements as contracts approach resolution. New products would remain fully collateralized until approved for margined treatment.
Open margined positions would also be subject to variation margin, so gains and losses would be transferred as settlement prices change rather than being left entirely to final expiration.
CMRA Perspective
The proposal changes not only the amount of collateral required, but also where risk sits in the clearing structure.
Under full collateralization, a participant’s maximum potential loss is largely pre-funded. Under risk-based margining, posted collateral may be lower than the maximum possible loss, increasing reliance on the accuracy of the margin model and the clearinghouse’s ability to collect additional collateral as market conditions change.
This is particularly important for event contracts, where prices can move sharply as new information arrives or as resolution approaches. Initial margin therefore needs to capture not only ordinary volatility, but also jump risk, liquidity constraints and concentration risk. The timing and effectiveness of variation-margin collection also become critical if large price moves occur before additional collateral can be obtained.
Portfolio offsets introduce another layer of model risk, particularly where historical relationships may break down during stressed or event-driven markets.
If a member defaults and posted margin proves insufficient, Klear’s default-management resources—including member margin, Company Contributions and the Guaranty Fund—become the next line of defense.
The key question is therefore whether the framework can deliver greater capital efficiency without creating materially greater exposure to model error, liquidity stress and member default.
