The Order That Actually Changed What Kalshi Sells Came From a County Courthouse

Everyone covering prediction markets this week is looking at Washington, D.C. The more instructive Washington is the state, and the more instructive judge is not on any federal bench.

King County Superior Court Judge John McHale had already granted Washington a preliminary injunction against Kalshi in July. In August he entered the order that matters, and Attorney General Nick Brown's office announced it on the 13th. It does something the appellate opinions have carefully avoided doing: it names the products Kalshi has to switch off, hands the company a two-stage engineering schedule to switch them off with, and attaches a price to every day it does not.

Correcting our own file first. This morning this site described the Washington ruling as coming from a federal judge. It did not. It is a state trial court, and that distinction is the entire point of what follows.

What the order actually requires

Kalshi must geofence Washington users out of eight categories: sports, elections, politics, entertainment, culture, tech, science, and what the industry calls "mentions" — contracts on whether a named public figure will say a particular word. It may keep offering commodities, climate, economics and finance markets in the state. Holders of positions in the prohibited categories may close them out rather than being stranded. Kalshi is also barred from advertising the covered categories to Washington consumers.

The schedule was staged, which is the part worth studying. An IP-address-and-residency geofence had to be live by August 19. A multi-source solution — one that leans on GPS signals rather than IP alone, because IP alone is trivially defeated — was due September 2, which is today. Miss it, and the state can collect $120,000 a day until it is fixed.

McHale did not arrive at that posture gently. He found Kalshi had "willfully ignored" a December notice from the Washington State Gambling Commission stating that event-based contracts were not authorised in the state. Brown's framing was similarly unsparing: "Kalshi has gotten rich promoting wagers on sports, elections, natural disasters, events related to the Iran War, and more."

Kalshi's answer, through spokesperson Jacki McGavick, was that the company "respectfully disagree[s] with the court's decision and are considering all legal options" — and, on Brown's characterisation specifically, that Kalshi does not offer markets on wildfires and does not offer markets on "war, death, or terrorism." That is a direct factual dispute with the attorney general about what is on the platform, and it has not been adjudicated. It should be reported as the open question it is rather than as spin, because if Kalshi is right, the state's most quotable line is also its least accurate.

Why a county judge matters more than a circuit court right now

The preemption fight decides whether states have authority. It does not decide what they can practically do with it, and those are different problems.

An appellate ruling that a state may enforce its gambling laws is a permission slip. It does not tell a regulator how to make a nationwide exchange stop serving residents of one state, and it does not solve the enforcement problem that has beaten state gambling regulators for twenty-five years: the defendant is a website, the customers are inside your borders, and your remedies are slow.

McHale's order solves it by declining to treat the remedial half as a gambling case at all. It treats geofencing as a deliverable with a specification and a due date, and prices non-delivery per day. That is a construction-contract remedy, and it works on a technology company in a way a cease-and-desist letter does not, because it converts open-ended legal risk into a line item a finance department can model. $120,000 a day is $43.8 million a year. Kalshi turned over $29.2 billion in June alone; the number is survivable. It is not ignorable, and it compounds while you appeal.

Every attorney general in the country now has that template, and it does not depend on how the Supreme Court rules. If states win the preemption question, this is how they enforce it. If Kalshi wins, states will point the same remedy design at the venues federal registration does not reach — a much larger group than the two or three exchanges that get the coverage.

Kalshi's complaint, and the part of it that lands

Kalshi has pushed back twice, and the two filings name different rivals.

In late August it moved for reconsideration, arguing Washington was enforcing arbitrarily against it while leaving competitor Nadex alone. The company's litigation head framed it as "asking for the same treatment the Washington AG is giving other prediction markets," and said the episode is "exactly why prediction markets are regulated at the federal level." Then, on August 28, head of litigation Jovy Dedaj wrote to Washington State Gambling Commission executive director Tina Griffin alleging "selective non-enforcement," this time naming Polymarket — an unregistered offshore venue, in Kalshi's characterisation — along with other designated contract markets and futures commission merchants operating in the state untouched.

As a legal defence this goes nowhere and Kalshi's lawyers know it. Regulatory and prosecutorial discretion is broad; a state does not have to sue everyone to sue anyone. Attorney general spokesperson Mike Faulk gave the standard answer, adding that Kalshi is "the largest entity of its kind."

As a policy critique it is far better than its legal form, and it deserves an answer rather than a procedural brush-off. If the state's theory is that these contracts harm Washington consumers, a Washingtonian geofenced off Kalshi who walks to an unregistered offshore platform has not been protected. They have been moved from a venue with federal registration, published rulebooks, an identified clearinghouse and a US legal address to one with none of those. "The largest entity of its kind" is an honest answer and also an admission that targets are being chosen by visibility.

The state's better reply — which nobody has made this week — is that partial enforcement still reduces aggregate harm, and that starting with the biggest venue is triage rather than hypocrisy. That argument works. It is just not the argument the state is making.

What we do not know tonight

Whether Kalshi met today's deadline. There was also a hearing set for today in King County on the company's motion for reconsideration. We have no filing, order or reporting on either as of publication, and we are not going to guess at the compliance status of a company facing a five-figure daily penalty.

We also cannot fully settle the date. The attorney general's own release, OPB and KUOW all put the multi-source geofencing deadline at September 2. One trade outlet, Covers, has reported it as September 4. We have used September 2 because it is what the state published and what the contemporaneous local reporting says, and we are flagging the discrepancy rather than quietly picking a side.

What is already settled is the part that outlives this case. Kalshi has built a Washington geofence. That engineering exists now, it can be aimed at any state, and the marginal cost of the next one is close to zero. Whatever the Supreme Court says about Dodd-Frank next summer, the technical capacity for state-by-state fragmentation of a self-described "nationwide exchange" was constructed this August, under court order, in Seattle.
