On 2 September 2026 KalshiEX has to have a multi source geolocation system running in Washington or start paying the state 120,000 dollars for every day it does not. The document that set the date is the amended preliminary injunction signed by Judge John F. McHale of the King County Superior Court on 12 August 2026 in State of Washington v. KalshiEX, LLC, case number 26-2-10264-3 SEA. What makes it worth reading in full is that it did not close a venue. It sorted one, using the exchange's own category names.
We have written before that a venue should be able to say which of its own markets it would refuse to list. This is what happens when someone else runs that exercise instead.
Seven subject areas stop and four keep trading
Paragraph 3 tells Kalshi to cease marketing, promoting, conducting, operating, facilitating, distributing, offering or accepting event contracts in Washington that relate to sports, elections, politics, entertainment, culture, tech and science, or mentions. It then states the other half in one sentence: this does not include bets in the categories Commodities, Climate, Economics and Finance. The platform stays reachable from Washington. Part of its book does not.
Three further provisions sit around that split and get less attention than they deserve. Kalshi must preserve all records relating to Washington consumers, and the order lists geolocation and location determinations by name alongside logs, communications and marketing data. It must hold the status quo on transaction fees taken from consumers who identified as Washingtonians. And users are explicitly not prevented from exiting positions they already hold, while the State reserves the right to seek recovery of fees and losses incurred on or after 2 September 2026. Access can be switched off in an afternoon. Exposure that is already open cannot, which is the problem we described in Venue Risk.
None of this is a final judgment. A preliminary injunction rests on likelihood of success, here on claims under the state Gambling Act and the Consumer Protection Act at RCW 19.86.020. The Attorney General's Office announced the underlying ruling in a release stating that the court found Kalshi likely violated both, and that the parties had until 5 August to confer on the terms of the injunction.
The court took its category names from the platform's own navigation
Read paragraph 3 again and notice the sentence after the subject list. The prohibition covers those subjects, including but not limited to the markets listed in the Sports, Elections, Politics, Culture, Tech and Science, and Mentions tabs on the defendant's platform. Six product tabs, named in a court order as the working description of what has to stop.
That is not an accident of drafting. The second finding of fact records how the platform organises itself, listing Elections, Politics, Sports, Culture, Crypto, Commodities, Climate, Economics, Mentions, Finance, and Tech and Science. The state did not invent a taxonomy. It picked up the one the exchange publishes to help users find markets, and made it the boundary of an injunction.
The July release also shows how the terms were reached. The parties conferred, and the list of materials the court reviewed includes a joint submission from both sides regarding the order granting the injunction. The categorisation is therefore not something a judge improvised. It is closer to a negotiated schedule drawn on a map the exchange itself drew, which is why every other venue should look at its own navigation menu and ask how it would read in this position.
One category on the court's own list lands in neither half
Do the arithmetic and a gap opens. The findings record eleven categories. Six are named as prohibited tabs, four as permitted. That leaves Crypto, which appears in the court's description of the platform and then in neither list.
A venue in that position decides the eleventh category on its own, under an order whose prohibition is written as including but not limited to the named tabs. The safe reading and the profitable reading point in opposite directions, and the party that guesses wrong is the party facing a daily penalty. A crypto price threshold contract looks like Finance. A contract on whether a named protocol ships an upgrade this quarter looks a great deal like tech and science. Nothing in the order resolves that, because it was written against tabs and the question lives underneath them.
A tab is not a classification, and this order shows why
The mismatch runs the other way too. Entertainment is prohibited as a subject, but there is no Entertainment tab in the list the court recorded, while Culture has one and is also prohibited. So a contract on an awards ceremony is caught twice over here, and treated very differently one level up: under the definitions the Commission proposed in June 2026, an awards contract is a contest rather than gaming, which puts it outside the Special Rule factor list entirely. One contract, three answers, and only one of them was ever meant to be a legal statement. The British split between the Gambling Commission and the FCA makes the same point from the other direction, sorting by what the contract points at rather than by where the product team filed it.
The remedy names a vendor and two dates
Paragraph 2 of the order is a project plan. IP address and residency based geofencing by 19 August 2026, then a multi source solution provided through GeoComply by 2 September 2026, designed to stop anyone located inside Washington from purchasing a covered contract. A named vendor, in an injunction, with a delivery date.
The first milestone landed. Covers reported that Kalshi began restricting access to sports event contracts for Washington users on 19 August 2026, and quoted a company spokesperson saying it disagreed with the decision and was considering all legal options. Between the order and the first control going live there were seven days, and the control that had to work on day seven was the simpler of the two.
Diligence is the only defence the order leaves open
The penalty clause is more interesting than the number in it. If implementation with GeoComply is not complete by 2 September 2026, Kalshi either pays 120,000 dollars a day until it is, or files a sworn affidavit from a Kalshi or GeoComply representative explaining why. The court then hears the State, decides whether Kalshi acted with sufficient diligence, and sets any penalty itself.
That turns an engineering record into a legal instrument. The affidavit is worth only what the evidence behind it supports: contracts signed on a date, integration tickets, test results, accuracy measurements, the record of what was tried when a control failed. A venue that runs geolocation as an afterthought has nothing to put in that document. A venue that treats it as a product system has it almost written already.
Washington gets whatever Michigan and Nevada get
One clause in paragraph 2 deserves more attention than it has had. Kalshi has to give Washington the same information and updates about the GeoComply rollout that it gives Michigan and Nevada, and has to let Washington talk to GeoComply directly, together with Kalshi's counsel.
A state court wired itself into a reporting channel built for two other states. Whatever the venue tells one regulator about how its geolocation works becomes visible to the next, and the working standard becomes the most demanding of the three. This is Directive 05 made mechanical: standards are set against the jurisdiction that regulates next, and compliance artefacts arrive at the next enforcement action ahead of you.
The federal statute the defence relied on assumes state by state differences
The conclusions of law contain the part that matters most outside Washington. Kalshi argued that federal law preempts state gambling enforcement. The court disagreed at every level, and one strand of the reasoning is unusual enough to quote. Looking at the Special Rule for event contracts at 7 U.S.C. section 7a-2(c)(5)(C), the court noted that the provision lists activity that is unlawful under any Federal or State law among the things the Commission may weigh, and concluded that "certain types of contracts and transactions may be allowed in some states and not in others." A footnote adds Commission Regulation 40.11(a)(1), which uses the same language.
Set aside whether the preemption analysis survives appeal. The structural observation stands on its own, and the category should have made it first. The federal provision that governs event contract review has state law written into it. A book that can be sorted jurisdiction by jurisdiction is not a concession extracted by a hostile state. It is the operating assumption of the statute the exchanges cite in their own defence, and we said as much when we argued for operating under the strictest live reading while the courts disagree.
Impartial access was tested as a defence and did not hold
The most common objection to per state sorting is that it breaks the access duty a designated contract market owes its participants. The court quoted Commission Regulation 38.151 in full and read it as what it says it is: a requirement of impartial, transparent and non discriminatory access criteria and comparable fee structures. In the court's words, "an anticipated inability to match Washington traders with other traders nationwide is not discrimination in providing access."
This is one state trial court, and other judges have read the federal questions differently. But a venue that plans to answer a state with the access rule should notice how quickly that answer was disposed of here. Geoblocking a subject area is not a denial of impartial access. It is a listing decision with a geography attached, and the twelve factor test the Commission proposed in June 2026 is the closest thing the category has to a shared way of writing those decisions down.
The state wrote its reason into the findings, and it is a health reason
The findings of fact do not read like a jurisdictional squabble. They cite the Washington Legislature's finding that some residents are negatively impacted by problem gambling, the state Supreme Court in Rousso v. State on how online access removes the friction of showing up in person, and the 2021 Washington State Adult Problem Gambling Prevalence Study, in which moderate to severe problem gambling ran at 10.3 percent among online gamblers against 2.6 percent among those who gambled only at physical venues. The findings also point to peer reviewed work by Nizan Geslevich Packin and Sharon Rabinovitz published in April 2026, describing prediction markets as sharing structural and functional similarities with online gambling while carrying more legitimacy and less regulation.
We are not neutral about that argument, and not in the direction people expect. We think prediction markets should exist. We also think the ratio between online and physical harm in that study is the most important number in the whole document, because it is the reason the category keeps meeting this kind of order. Directive 06 commits signatories to revenue from many informed participants over years rather than a few ruined ones over months. A venue that cannot show what it does about the 10.3 percent has no answer to the finding, and the finding is what the injunction is built on. The Washington Gambling Act at RCW 9.46 supplies the legal hook. The prevalence study supplies the motive.
A competitor's arrangement became the argument for reconsideration
KOMO News reported on 21 August 2026 that Kalshi had asked Judge McHale to reconsider the amended injunction or stay parts of it, pointing to an 18 August agreement under which the Attorney General's Office and the Gambling Commission would hold off enforcement against North American Derivatives Exchange, which trades as OG and holds the same federal designation. Per that report the motion was noted for 2 September 2026 without oral argument, the same day the geofencing deadline falls. The Washington State Standard, in reporting carried by OPB on 14 August 2026, had already noted that the state appeals court declined to pause the injunction while Kalshi seeks review.
Take the fairness complaint at face value, because it is a real one. Two federally designated exchanges offering comparable contracts into the same state under different practical constraints is a bad outcome for everybody, the state included. But notice what the remedy looks like when it is pursued venue by venue. Each exchange negotiates its own arrangement on its own timeline, and the category ends up with a patchwork nobody designed. A standard the industry writes for itself is the only version of this that applies to every venue at once.
What a venue should be able to produce before a court asks for it
The concrete version of everything above:
- A classification per contract, not per tab. Every listed market carries a subject classification mapped to the prohibited subjects of each jurisdiction you reach, kept separately from the browsing category shown to users.
- A named person who signs it. When a court adopts your taxonomy, someone has to be able to say who assigned it and on what basis.
- A written treatment of the residual. The categories that fit neither list, the way Crypto fits neither list here, are where the penalty risk concentrates.
- Geolocation integrated before it is ordered. A vendor contract signed under a deadline is a worse contract, and a rollout under a deadline produces the affidavit rather than the system.
- Retention of location determinations. This order requires it. Assume the next one will too.
- A plan for open positions. Exits have to keep working when new purchases stop, per the same continuity logic that showed up in the CFTC's emergency order in August 2026.
- Advertising that can exclude a state. The order reaches marketing and requires good faith efforts to keep Washington out of national campaigns where technically feasible. That is an ad operations capability, not a legal position.
The classification you write yourself is the one you get to explain
The Washington order will be argued about for months and parts of it may not survive review. That is not the lesson. The lesson is that a court, a state attorney general and a geolocation vendor sorted a prediction market's book into permitted and prohibited in about three weeks, using category names the exchange had published for its own users, and that the exchange's role was to confer on the terms and then build to the deadline.
Every venue in this category has the same map sitting in its product. The difference between the ones that get to explain their own classification and the ones that get handed a classification is whether they wrote it down first, with reasons, per jurisdiction, before anyone asked. As of 1 September 2026 the multi source deadline has not yet arrived and the reconsideration motion has not been decided. Both will resolve. The structural question they raise does not resolve with them.
