Wisconsin refuses the CFTC the order Minnesota granted it two days earlier

On Monday 27 July a federal judge in Minnesota gave the CFTC, Kalshi and Polymarket a preliminary injunction against a state ban. On Wednesday 29 July a federal judge in Wisconsin refused the CFTC a preliminary injunction against that state's gambling laws. Same statute at the centre, same week, opposite results — and neither order decides the question. Here is what was in front of each court, what this one does not settle, and which widely-repeated claim about it we could not stand up.

Every external fact below was fetched and read on 2026-07-30 from the source named beside it. This is information, not legal or betting advice.

What this decides — and what it does not

A refused preliminary injunction is not a ruling that anyone broke the law. It means the party asking for an emergency order — here the CFTC — did not persuade the court to grant one at this stage. The federal case continues. The pre-emption question at its centre, whether the Commodity Exchange Act displaces a state's gambling law, has not been finally answered by this court or any other.

So: nothing was struck down, no platform was ordered to stop anything by this order, and no penalty was imposed. What changed on 2026-07-29 is that Wisconsin is not restrained from enforcing its gambling laws while the federal case proceeds. The separate suits Wisconsin filed against five platforms in April are their own proceedings.

And one thing this page deliberately does not do: it does not describe the ruling as the platforms' first federal-court loss of 2026, because the record does not support that. The earlier ones are listed and dated below.

The ruling, by the numbers

29 Jul 2026

CFTC's preliminary injunction denied

Coinpedia reports that on 29 July 2026 U.S. District Judge William Griesbach denied the CFTC's request for a preliminary injunction against Wisconsin. The Commission had asked the court to stop the state enforcing its gambling laws against prediction-market platforms offering sports event contracts.

The district — corrected before publication

Two independent sources place the case in the U.S. District Court for the EASTERN District of Wisconsin: crypto.news, in the syndicated excerpt we could read, identifies “Judge William Griesbach of the U.S. District Court for the Eastern District of…”, and PlayUSA reported in May that the Department of Justice and the CFTC filed the suit in that district. We could not confirm this from the docket itself.

Whom Wisconsin sued first

The federal case is an answer to a state one. RotoWire's legal timeline records that on 23 April 2026 the Wisconsin Department of Justice filed suits against Kalshi, Robinhood, Coinbase, Polymarket and Crypto.com over what it called “illegal sports betting.”

When the CFTC sued Wisconsin

In its own release the CFTC said it sued Wisconsin “in response to the state's lawsuits against Kalshi, Polymarket, Crypto.com, Robinhood, and Coinbase, five CFTC-regulated prediction markets,” filed “less than one week” earlier and “asserting felony violations of state law.” Chairman Michael S. Selig: “States cannot circumvent the clear directive of Congress.”

Kalshi and Crypto.com denied intervention

Coinpedia reports the court also rejected motions by Kalshi and Crypto.com to intervene in the CFTC's case. Separately, Gambling Insider reported on 17 July that the American Gaming Association had moved to intervene in the same case, that Wisconsin did not oppose it and that federal regulators did.

The interim-relief record before this ruling

Gambling Insider, citing gambling attorney Daniel Wallach, reported on 21 July 2026 that courts had by then issued 23 decisions on preliminary-injunction or temporary-restraining-order requests in prediction-market cases, with states prevailing in 19 of them. That is the number this ruling joins — not a first.

What was actually in front of the court

Wisconsin moved first. RotoWire's legal timeline records the state's Department of Justice filing suits on 23 April 2026against Kalshi, Robinhood, Coinbase, Polymarket and Crypto.com over what it called “illegal sports betting” (RotoWire, 2026-04-23). Five days later the CFTC sued the state. In its own words, the Commission filed “in response to the state's lawsuits against Kalshi, Polymarket, Crypto.com, Robinhood, and Coinbase, five CFTC-regulated prediction markets,” noting the state suits had been brought “less than one week ago” and asserted “felony violations of state law” (CFTC, press release 9220-26, 2026-04-28).

The Commission's theory is the same one it has run against every state: Congress gave it exclusive jurisdiction over event contracts traded on designated contract markets, so a state cannot reach them through gambling law. Chairman Michael S. Selig put it plainly in that release: “States cannot circumvent the clear directive of Congress. Our message to Wisconsin is the same as to New York, Arizona, and others: if you interfere with the operation of federal law in regulating financial markets, we will sue you” (CFTC, 2026-04-28). PlayUSA reported that the Department of Justice joined the Commission in the suit, filed in the U.S. District Court for the Eastern District of Wisconsin, seeking declaratory and injunctive relief (PlayUSA, 2026-05-01).

On 2026-07-29that request for interim relief was refused. Coinpedia reports Judge Griesbach found that registration with the CFTC does not automatically shield the platforms from state gambling laws, that the Commodity Exchange Act does not automatically cancel Wisconsin's gambling rules, that the plain language of those rules could cover sports-related event contracts, and that the CFTC had not shown enough irreparable harm to justify blocking enforcement. Coinpedia also reports the court rejected motions by Kalshi and Crypto.com to intervene in the Commission's case (Coinpedia, 2026-07-29). We could not read the order, so each of those is the reporting's account of the court's reasoning rather than the court's own language, and this page carries no quotation from it.

The divergence, dated

The reason this ruling matters is not its size — it is an interim order in one district — but its direction. Within seventy-two hours two federal judges took the same federal statute and the same pre-emption argument and went opposite ways, and an appellate court has already answered the question a third way. That is the state of the record, laid out by date:

2026-04-06Third Circuit — federal law pre-emptsFor the platforms

2026-07-09S.D.N.Y. — Kalshi's injunction deniedFor the state

U.S. District Judge Analisa Torres denied Kalshi's motion for a preliminary injunction, ruling that New York's gambling laws are not pre-empted by the Commodity Exchange Act. RotoWire dates the order 9 July; Gambling Insider, reporting on a later motion, also refers to “the order she made on July 9.”

2026-07-21Washington state court — injunction against KalshiFor the state

A Washington state judge granted a preliminary injunction against Kalshi and expressly rejected the pre-emption argument, writing that “the Commodity Exchange Act (CEA) does not preempt Washington State gambling law” and that “regulation of gambling and regulation of futures markets are different fields of regulation.” This is a state court, not a federal one.

2026-07-27Minnesota — the ban enjoinedFor the platforms

U.S. District Judge Katherine Menendez granted the CFTC, Kalshi and Polymarket a preliminary injunction blocking Minnesota's felony ban days before its 1 August effective date. Gambling Insider reports the ruling ran to 44 pages and included the observation that if the platforms' contracts do not fit the federal definition, “Plaintiffs have much weaker claims that the CFTC is the only authority that can regulate them.”

2026-07-27S.D.N.Y. — second denial, same dayFor the state

Hours after the Minnesota order, Judge Torres denied Kalshi an injunction pending appeal, in a three-page order finding it sought “the very injunctive relief that (this) court already denied” and that “defendants have laid out significant harms associated with halting their efforts to enforce state gaming regulations.” Gambling Insider reports Kalshi had by then filed its appeal to the U.S. Second Circuit Court of Appeals.

2026-07-29Wisconsin — the CFTC's injunction deniedFor the state

Two days after Minnesota, Judge Griesbach refused the CFTC the relief Judge Menendez had granted it. Coinpedia reports the court found that registration with the CFTC does not automatically shield platforms from state gambling laws, that the Commodity Exchange Act does not automatically displace Wisconsin's gambling rules, that the plain language of those rules could cover sports-related event contracts, and that the CFTC had not shown enough irreparable harm.

The labels above record which way each order ran. They are not a score, and the list is not a prediction: an appellate ruling outranks a district order, an interim order outranks nothing, and several of these are on appeal. For the durable state-by-state reference rather than this single dated ruling, see is Polymarket & Kalshi legal; for the order that ran the other way two days earlier, see the Minnesota injunction.

The claim we could not stand up

The ruling reached us described as the prediction-market platforms' first federal-court loss of 2026. We could not confirm that from any source, and the dated record contradicts it. RotoWire's legal timeline, fact-checked and last updated 23 July 2026, records a Massachusetts federal judge granting the state authority to ban Kalshi's sports event contracts on 20 January; a federal court in Ohio denying Kalshi a preliminary injunction and holding that sports event contracts do not qualify as “swaps” on 10 March; a federal judge denying Kalshi a preliminary injunction against Arizona on 9 April; and a Michigan federal court granting an injunction on 5 July. Judge Torres denied Kalshi in the Southern District of New York twice, on 9 July and again on 27 July (Gambling Insider, 2026-07-28).

Gambling Insider, citing gambling attorney Daniel Wallach, put the running count on 21 July 2026 at 23 decisions on preliminary injunctions or temporary restraining orders in prediction-market cases, with states prevailing in 19 of them (Gambling Insider, 2026-07-21). Against that record, a denial in Wisconsin is not a first of anything obvious. What is narrower — and might be distinctive — is that the motion refused here was the CFTC's own, rather than a platform's. No source we could open makes that point either, so we record it as an observation about the posture and not as a claim about a first.

What we could not verify

An honest gap beats a confident error, so, as of 2026-07-30:

  • The order and the docket.CourtListener returned an empty body to our fetcher for both the docket and the specific entry the reporting links to. We therefore state no docket number, no case number, no page cite, and no quotation from Judge Griesbach's order anywhere on this page.
  • The originating report. The account that appears to originate this story, on crypto.news, could not be fetched directly — only a syndicated excerpt of it. The detail we take from that excerpt is the district, and it is corroborated independently by PlayUSA.
  • The district, from the court. Two sources say Eastern District of Wisconsin and none says Western; we could not confirm it from the docket. We flag this because the summary that reached us said Western, and it appears to be wrong.
  • Any statement from a party.We found no CFTC release on this denial — the Commission's press room carries its April filing announcement and nothing dated to the ruling — and no statement from the Wisconsin Department of Justice. Neither absence means one does not exist.
  • An appeal.Coinpedia reports that Kalshi and the CFTC are “expected to appeal” to the Seventh Circuit and that the Wisconsin cases are expected to return to state court. Those are expectations in the reporting, not filed events; we found no notice of appeal and do not record one. For the same reason we omit a lawyer's forecast, quoted in the same report, about what Wisconsin judges might do next.

What Monitoring shows — and what it doesn't

Monitoring reports what has been filed, argued and ordered, each with a date and a named source. It does not forecast the outcome of this or any case, does not price it, does not take a position on whether any statute should stand, and does not tell any reader whether they may lawfully trade anywhere. Where a court order and a party's characterisation of it differ, both are attributed above and the reader is left to weigh them. Where we could not read a document, we say so rather than describe it.

Common questions

Did this ruling make prediction markets illegal in Wisconsin?

No. What happened on 29 July 2026 is that a federal judge declined to grant the CFTC a preliminary injunction — that is, he refused to order Wisconsin to stop enforcing its gambling laws while the federal case proceeds (Coinpedia, 2026-07-29). A denial of interim relief is not a ruling that anything is illegal, and it is not a final judgment on the pre-emption question. The separate suits Wisconsin filed against five platforms in state court in April are their own proceedings and have their own timetable. This page does not tell any reader whether they may lawfully trade anywhere.

Was this the platforms' first federal-court loss of 2026?

Not on the record we can see, and we could not find a source that says so. Earlier 2026 decisions running against the platforms' side include a Massachusetts federal judge granting the state authority to ban Kalshi's sports event contracts (20 January), a federal court in Ohio denying Kalshi a preliminary injunction and ruling that sports event contracts are not “swaps” (10 March), a federal judge denying Kalshi a preliminary injunction against Arizona (9 April), a Michigan federal court granting an injunction (5 July), and Judge Torres in the Southern District of New York denying Kalshi twice, on 9 and 27 July (RotoWire legal timeline, 2026-07-23; Gambling Insider, 2026-07-28). Gambling Insider, citing attorney Daniel Wallach, put the running tally at 23 interim-relief decisions with states prevailing in 19 (2026-07-21). What is narrower and may be distinctive is that this denial was of a motion brought by the CFTC itself rather than by a platform — but no source we could open characterises it that way either, so we do not assert it.

What does a denied preliminary injunction actually decide?

A preliminary injunction is interim relief, granted or refused before a case is decided; courts weigh factors including whether the moving party is likely to succeed on the merits and whether it faces irreparable harm without an order. A denial means the moving party did not clear that threshold at this stage. It does not resolve the merits, and it does not bind other courts. Coinpedia reports the court found that registration with the CFTC does not automatically shield platforms from state gambling laws and that the CFTC had not shown enough irreparable harm (Coinpedia, 2026-07-29) — but we could not read the order, so those are the reporting's characterisations of the court's reasoning and not the court's own words. This is a general description of procedural posture, not legal advice.

Does Monitoring say how this case will end?

No. Monitoring reports what has been filed, argued and ordered, with a date and a named source for each. It does not predict the outcome of litigation, does not price it, does not tell anyone whether they may lawfully trade anywhere, and is not affiliated with any exchange or platform. Where reporting describes something as expected rather than filed, we label it as an expectation and put it in the gaps section.
