Kalshi asks CFTC to greenlight margin trading for event contracts
Prediction market operator Kalshi has formally asked the Commodity Futures Trading Commission to approve a margin framework for eligible event contracts, a move that would bring leveraged trading to a platform best known for fully collateralized binary markets while limiting access to qualified institutional participants.
The request was submitted on Sept. 22 by Kalshi Klear, the company’s clearinghouse, which filed proposed amendments to its rules and margin risk framework under CFTC Regulation 40.5(a). If approved, the changes would introduce a new initial margin method for selected event contracts covering economic data, financial developments, politics, commercial activity and other objectively verifiable events.
Not every market on the platform would qualify. Contracts tied to sports events would not receive margined treatment under the proposal, and Kalshi told CNBC that its culture and mention markets, where traders bet on whether a person says a particular word or phrase, would also remain outside the program.
From fully collateralized to risk-based margin
Under Kalshi’s current structure, event contracts are binary products that settle at 1 USD when a specified outcome occurs and zero when it does not. Before settlement, prices trade between those two values, leaving each side of a trade with a defined maximum possible loss. A trader holding a YES position can lose no more than the price paid, while the maximum loss on the opposing NO position equals 1 USD minus the YES price.
That bounded payoff structure allows Kalshi’s clearinghouse to calculate margin separately for each side of a contract. Rather than requiring traders to post enough funds to cover the full possible loss at the outset, the proposed framework would set initial margin according to modeled adverse price moves. A qualifying participant could therefore control more contracts than would be possible under the platform’s fully collateralized structure.
Each newly listed product would initially remain fully collateralized until Kalshi reviewed and approved it for margin. The clearinghouse could designate both sides of a binary contract for margin, approve only the YES or NO side, or keep both sides fully funded.
Institutions only, retail stays out
Margin would not become available to every Kalshi customer. Eligible contracts could be cleared only through a registered futures commission merchant, or FCM, or by an eligible contract participant approved by Kalshi Klear as a self-clearing member. Eligible contract participants generally include institutions and other entities meeting financial thresholds defined under United States commodities law.
The restriction positions the product for hedge funds, trading firms and other professional market participants rather than ordinary retail accounts, a design choice likely aimed at deflecting the kind of consumer protection criticism that has followed the prediction market industry’s rapid growth.
Kalshi’s filing also addresses the asymmetric risk of early resolution. Early or sudden resolution may create different risks for the two sides of a contract, so the company plans to calculate eligibility and margin requirements separately instead of treating opposing positions as identical. Collateral requirements would rise as a contract approaches expiration or when market conditions increase the risk of abrupt repricing, with contracts eventually reaching full collateralization near resolution even if they retain their formal classification as margined contracts.
Scheduled events capable of causing sharp price changes would trigger additional requirements. Kalshi also proposed volatility floors, concentration charges and liquidity adjustments designed to account for the cost of closing positions after a clearing member default.
A one-day risk period with 99 percent confidence
Kalshi has requested permission to use a one-day, 24-hour margin period of risk for qualifying products, representing the estimated time needed to manage or close a position after a default. Its model seeks to maintain a confidence level above the 99 percent minimum required by CFTC regulations, and the clearinghouse said it tested the framework using historical data while measuring performance separately for the YES and NO sides.
Among the safeguards is a dual-speed volatility measure that would raise margin quickly after a price shock but reduce it more slowly when conditions settle, preventing required collateral from falling too far during quieter trading periods. Portfolio offsets would be permitted only for related contracts with reliable payoff links, and before receiving the benefit a portfolio would need to pass loss backtesting under adverse conditions.
Kalshi said its guaranty fund would support margined event contracts and perpetual futures through separate contract segments. Fully collateralized customers would not lose posted collateral because of defaults involving margined positions, although a severe event could expose part of their profits to contract tear-ups when the other side contains a margined position.
Follows perpetual futures expansion
The institutional push builds on Kalshi’s existing leverage offering. The company has already introduced leveraged products through its United States perpetual futures business, after winning CFTC approval earlier this year to launch the first regulated Bitcoin perpetual futures in the country.
Under the filing’s timing rules, the proposed amendments would take effect no earlier than the first business day after the 45th calendar day following submission, unless Kalshi or the CFTC selects a later date. Several technical sections covering the model’s design, calibration and validation were withheld from the public document after the company requested confidential treatment.
For the broader prediction market sector, the filing signals where the industry believes the next phase of growth lies: institutional scale, professional risk management and CFTC-sanctioned leverage, rather than the retail-driven volume that built the category.

first CPI print settling under this framework and both sides getting liquidated at once is gonna be appointment viewing ngl
kalshi really said what if prediction markets had leverage. margin on fed decision contracts is gonna produce some spectacular liquidations
its initial margin on objectively verifiable events tho, not random mention markets. still gonna be chaos the first time a CPI print settles lmao
institutional only of course. retail stays fully collateralized while funds get leverage on fed decision markets. very cool
FCM intermediation is honestly the smartest line in the whole filing. no way the CFTC rejects a framework where retail never touches the leverage
fed_o_clock nailed it, FCM intermediation means the CFTC gets its leverage firewall and kalshi gets its margin. retail never touches the risk, that is the whole approval math
the one day risk period at 99 percent is actually pretty conservative tbh. this is closer to how CME margins everything else than some wild degen leverage scheme
cme comparison undersells it tbh, a binary settling at 0 or 1 has cleaner tail risk than most swap cleared stuff. the model risk is all in event resolution
Fair point, though early resolution risk on political contracts is where this gets messy. A surprise race call on election night breaks the models on both sides of the book.
and surprise race calls are exactly the case their review process will never approve for margin. anything with subjective resolution stays fully funded, smart carve out
Exactly the election night problem. A race called and then uncalled breaks both sides of the book at once. At least they had the sense to keep sports out of it
Institutions only, a documented risk framework, and sports plus culture markets excluded. This reads like it was written specifically to survive CFTC scrutiny
volatility floors, concentration charges, liquidity adjustments… kalshi clearly read the CFTC playbook front to back before filing this one
