When the Commission first registered Kalshi Klear LLC as a derivatives clearing organization on 28 August 2024, it did so, in the words of the Amended Order of Registration the Commodity Futures Trading Commission issued on 15 April 2026, "for the clearing of fully collateralized positions in swaps." Full prepayment was not a feature the venue chose and could market. It was the perimeter of the licence, and every argument about why a prediction market is not a casino rested quietly on it: a product whose maximum loss is money already handed over cannot produce a debt spiral.
That perimeter is being widened, the machinery is built, and we think it is survivable and in places useful. What worries us is narrower: the protection full collateralization gave was never explained to the people it protected, so its removal cannot be explained to them either.
Full collateralization was a condition of registration, not a product choice
The mechanism sits in Rule 7.5 of the Kalshi Klear LLC Derivatives Clearing Organization Rules, version 1.4, published on Klear's own public document store. Self-clearing members must hold funds covering their maximum downside exposure, and the rule closes without discretion: the Company "will not clear a position in a Fully Collateralized Contract that is not fully collateralized."
Rule 7.5C extends that to customers trading through a futures commission merchant: before the broker sends the order, the customer's funds must be on deposit and "must be reserved and made unavailable for uses other than collateralizing such an Order until the Order resolves." The worst case is therefore known at order entry, and known to the user, because it is the balance that just stopped being spendable. No later event can enlarge it. Almost nobody ever called that the consumer protection it was.
The machinery arrived in April and no user's position changed that day
On 20 April 2026 Klear's General Counsel, Richard Heaslip, filed a self-certification letter with the Commodity Futures Trading Commission moving the rulebook from version 1.3 to 1.4, effective after the close of business on 27 April 2026. It describes what was added: "a comprehensive framework for future products that are not fully cash collateralized (Chapter 7)" and "a new Chapter 12, which establishes the Company's default-management framework."
The same letter states that the amendments leave the economics, risk and operation of every contract then being cleared untouched, and that they build the structure needed for new products in later filings. Both are true, and together they are the quietest possible way for a protection to end: nothing happened to anybody's position in April, the paperwork just stopped standing in the way. We argued in March 2026 that margin would be the next fault line in this category, and this is the form it took: not an announcement, a definition.
A margin call can reach the account before the notice does
Chapter 7 gives Klear two ways to ask for money. The scheduled route, Rule 7.2A, runs after the close of each business day or on a published schedule. The unscheduled route, Rule 7.2B, lets the Chief Risk Officer call for margin intra-day whenever unstable conditions exist or a member carries risk "larger than is justified by the financial and/or operating condition of the Member."
The sequence is worth reading slowly. Klear gives notice of the amount due and then, "immediately after giving or making reasonable efforts to give the notice," tells the settlement bank to wire the funds out of the member's account. The debit is not conditional on the notice arriving. For a clearing member with a treasury desk that is ordinary plumbing. At the end of the chain it is the opposite of how a prepaid position behaves. Two further rules pull the same way: Rule 7.2F bars a broker from letting a customer withdraw funds that would drop the account below the prevailing initial margin requirement, and Rule 7.2D lets Klear refuse to release excess initial margin at all where the Chief Risk Officer finds that releasing it would be contrary to the clearing house's fiscal integrity.
Variation margin turns a paper loss into a payment that clears
Rule 7.4 changes the character of holding a position in three sentences. Where the price of a margined contract moves against a member, that member "shall be obligated to pay Variation Margin" to Klear and the member on the other side receives it. All such payments "shall be made in cash."
A fully collateralized position has no such cash flow: it moves on a screen and settles once. A margined position settles every cycle, in money, whatever the holder thinks of the move. Kalshi's own documentation shows the retail end of this for the perpetual contracts Klear already clears on margin: the Kalshi help centre page on perpetual futures states that "you need to post collateral to open and maintain a position," that leverage runs up to six times, that a balance below the maintenance threshold may trigger a margin call, and that if the call is not met "Kalshi may liquidate your position to prevent further losses."
Somebody else can close the position, and not necessarily on the open market
Chapter 12 answers the question a prepaid user never has to ask: who closes this if I cannot. Under Rule 12.2A, once a person ceases to be a member or is suspended they are barred from opening new positions and every open contract is closed out as expeditiously as practicable, by transfer to other members with Klear's consent, through an auction Klear runs, or by liquidation under Rule 12.3.
Rule 12.3B permits three methods: book entry offsetting the positions, liquidation on the open market, and "private auctions amongst qualified market participants invited or required by the Company to submit confidential bids," with Klear picking the best bid "based on the totality of the circumstances." Rule 12.3C lets Klear oblige other members to bid or accept allocations, capped proportionally to their own positions in the same product class, and Rule 12.3D makes what they learn confidential. Conventional, but it is price discovery the holder of the position cannot see, join or appeal, and its output is the price their position closed at.
Being directionally right stops being enough where gains get haircut
If the defaulter's money, the guaranty fund and the assessments described below are exhausted, Rule 12.5D sends Klear into a settlement cycle that pays out variation margin gains only to the extent losses came in. When they do not match, Klear invites voluntary contributions, then applies a Variation Margin Gains Haircut: gains are "reduced on a pro rata basis according to the amount of such gains," for that cycle and, absent a bankruptcy event, the next two business days, never past five.
Rule 12.5D-4 is the sentence that reaches an individual. Customer gains are haircut at broker level, and each broker "shall allocate the haircut of its Futures Customer Variation Margin Gains pro rata among its Futures Customers with net portfolio gains for the relevant settlement cycle." A user who read the event correctly, held the winning side and owed nothing to anybody is paid less than the position earned, because somebody unrelated to them failed.
Rule 12.5E goes further. Where the defaulting member's positions remain open after the last haircut cycle, Klear extinguishes them by a partial or full tear-up of the positions of members and customers who did not default, priced at the settlement price last established. And Rule 12.5C-10 records something easy to miss: haircuts and tear-ups "are not Assessments and are therefore not subject to the Assessment limits." The two tools that reach a customer's gains are the two that carry no cap.
The layers above the user are set out in Rule 12.5C and each must be fully used before the next: the defaulter's margin, the defaulter's guaranty fund deposit, Klear's First Tranche Company Contribution, the guaranty fund built from every other member's deposits, Klear's Second Tranche, then assessments on all non-defaulting members. Each Klear tranche is capped at "the greater of $20 million or 10% of the total aggregate value of the Guaranty Fund," and once applied, the rule says, "the Company will have no obligation to provide additional funds to replenish such contribution." Members get no such exemption, though Rule 12.5C-5 caps their assessments at 200 percent of their deposit requirement for one default and 550 percent for several inside six months. Who refills the pot is a governance question, and it sits beside the one we examined in the September 2026 piece on clearing houses that own one of their own clearing members.
The wall around a prepaid position is nearly complete, and Klear named the gap itself
None of this means a prepaid position funds somebody else's margin loss. Rule 12.6A says the opposite in terms: where the waterfall is exhausted, members and contract holders "shall have no recourse to any other funds or any other entity, including without limitation the Margin or Guaranty Funds that support clearing of other products ... the Margin held by the Company for Fully-Collateralized Contracts." That segregation runs both ways and is the document's strongest single protection.
The gap is one clause long, and Klear wrote it down rather than leaving it to be found. In the request for approval of the Event Contract Margin Framework that Chief Risk Officer Udesh Jha sent the Commission on 22 September 2026, the discussion of Core Principle F says that people trading fully collateralized event contracts "will not be subject to any aspect of the default waterfall resulting from such a default in a margined event contract position, except that in an extreme scenario a fully collateralized position could be subject to tear-ups only to the extent of the portion of profits of the position associated with opposite-side margined positions."
The next sentence is unambiguous that their collateral itself is never exposed. Read plainly: the money a prepaid user put in stays theirs, a slice of what they won might not. The exception is narrow and honestly disclosed, and it is still the first time a user who never opted into margin acquired an exposure to somebody who did.
A fully funded position is not a Fully Collateralized Contract once you are eligible
The amendment with the longest reach is a proviso in Appendix A of the September filing. It rewrites the definition of Fully Collateralized Contract so that contracts eligible for margined treatment, held by a participant eligible under Rule 3.2C, "will not be Fully Collateralized Contracts even if they are fully collateralized."
Proposed Rule 7.1A-3 completes the picture. For binary options Klear periodically raises initial margin so the contract "reaches full collateralization" as it nears expiration, when binary uncertainty is greatest, then adds that "any such increase in collateral shall not result in the Margined Contract becoming a Fully Collateralized Contract for purposes of these Rules." A position can therefore be backed, at the end, by one hundred percent of its maximum loss and still sit in the margined segment, inside the haircut and tear-up machinery.
The ramp is good engineering and we would argue for it. The naming is the problem. "Fully collateralized" stopped describing how much money stands behind a position and became a category assigned by product eligibility and participant class. Proposed Rule 7.1A-2 softens that, making full collateral the default for any swap Klear does not designate as margined and letting Klear margin the YES side of a market while leaving the NO side prepaid. Sensible, and it also means two users looking at one market can sit in different regimes, with nothing requiring the screen to say which.
The numbers that set the margin are in the sections nobody outside the agency can read
Klear requested confidential treatment for sections 2 through 4 of the September submission, along with "the detailed methodology whitepaper, calibration parameters, and validation packages that describe the Framework in mathematical terms." The public version keeps the design principles and redacts the mechanics. Those principles read well: coverage above the 99 percent confidence level required by Commission Regulation 39.13(g)(2)(iii), volatility floors so requirements cannot collapse in quiet markets, independent validation, sports excluded from margined treatment altogether, and clearing only through a futures commission merchant or an approved self-clearing member that is an eligible contract participant.
Confidential treatment for a calibration file is defensible: a published parameter set is a map of where to push. But the same submission promises, under Core Principle L, that Klear "will provide market participants with sufficient information regarding the Event Contract Margin Framework and applicable margin requirements." That promise is to the participant, not the regulator, and Directive 02 of our manifest says where it has to be kept: "Fees, spreads, settlement sources, custody arrangements and conflicts of interest are stated in plain language on the surface where the trade happens."
There is a clock on it. Under Commission Regulation 40.5(c)(1), as printed in title 17 of the Code of Federal Regulations, a rule submitted for approval "shall be deemed approved by the Commission" 45 days after receipt unless the submitting entity is notified otherwise, and Regulation 40.5(b) directs the Commission to approve unless the rule is inconsistent with the Act. It may extend the review by a further 45 days under 40.5(d)(1) or issue a notice of non-approval under 40.5(e). Counted from 22 September 2026 the forty-fifth day is 6 November 2026, and the submission says the amendments take effect no earlier than the first business day after it. As of 26 October 2026 we found no published Commission order approving, extending or declining the Framework. Silence is the route to approval.
Six sentences would make this legible to the person holding the position
We are not asking for the framework to be withdrawn. Risk-based margin on a bounded payoff is reasonable, excluding sports is a genuine act of restraint, and a category that wants institutional liquidity needs something like it. The gap is between a complete rulebook and a trading screen that says nothing.
Six disclosures would close it and none requires publishing a calibration parameter. Whether this position is prepaid or margined, in the rulebook's own words, on the ticket before the trade. The largest amount that can be taken from the account for it, which for a prepaid contract is the sum already reserved. Whether an intra-day call can debit the account before a notification is read. Who closes the position if a call is not met, and that the closing price may come from a private auction. That gains can be cut or a position extinguished because of a third party's default, with the five business day limit stated. And where the margin requirement for this market and this side is published.
A venue that writes those six lines has not weakened its product. It has told the truth about it earlier than it had to, which is the whole content of the standard this initiative exists to set.
