Kalshi is seeking regulatory clearance to introduce risk-based margining for selected event contracts, potentially reducing the collateral required from institutional participants. Sports markets would remain fully collateralised.
Kalshi’s event contracts currently require traders to post enough collateral to cover their maximum possible loss. Under the proposal, Kalshi Klear would instead set initial margin based on the estimated price movement during a one-day period for closing the position.
The requirement would remain capped at the maximum possible loss. The proposed model is designed to exceed the CFTC’s 99% confidence standard for projected losses.
How Kalshi Would Set Margin
Kalshi could apply different requirements to the YES and NO sides of the same market. One side could qualify for risk-based margin while the other remains fully collateralised if an unexpected resolution would create unequal risks.
Collateral requirements would rise as a contract approaches settlement and eventually reach the position’s maximum possible loss. Kalshi could accelerate that increase before scheduled events likely to cause a sharp price move or when developments related to the underlying event raise the risk.
Illiquid or concentrated positions could also require additional collateral. Related contracts may receive portfolio-margin offsets if their prices or payouts are closely connected.
Kalshi would test each proposed group against potential portfolio losses before allowing the offsets. New markets would remain fully collateralised until Kalshi determines that they meet its margin criteria. Sports contracts are expressly excluded from the proposed model.

Access Would Remain Restricted
Margined contracts could be cleared only through a futures commission merchant or by an eligible contract participant accepted by Kalshi as a self-clearing member. The proposal therefore does not introduce margin as a general feature for all platform users.
In a memo provided to CNBC, Kalshi said lower collateral requirements could make longer-dated prediction markets more attractive to institutional traders.
Potentially eligible contracts may cover economic, financial, political, commercial and other objectively verifiable events. Risk-based margin would allow participants to control positions without posting their full maximum loss at the outset.
That does not necessarily mean Kalshi would lend money directly to traders; the proposal changes how much collateral the clearing house requires against eligible positions.
The rule amendments remain subject to CFTC review and could take effect no earlier than the first business day after the 45-day review period, or on a later date agreed with the regulator.
Kalshi has not announced a launch date, while the redacted model parameters make it impossible to determine how far collateral requirements could fall for eligible contracts.
