Stake.us 8th Circuit Appeal Brief: Arbitrator, Not Judge

Stake.us filed its opening brief in the Eighth Circuit on September 11, 2026, and its central argument is that a private arbitrator, not a federal judge, should decide whether the Stake.us terms and conditions are void under Minnesota gambling law. We downloaded the 6,272-word brief and read it. The player's answering brief is due October 13.

This is the appeal that matters most to anyone who has ever clicked "I have read and agree to the terms and conditions" at a sweepstakes casino. A Minnesota judge ruled on July 1 that this particular arbitration clause cannot be enforced, because the clause is written so that it depends on the validity of the contract around it, and the legality of that contract is the thing being challenged. If the Eighth Circuit agrees in a published opinion, the reasoning binds every federal district court in seven states. If it reverses, the clause holds and these disputes go back behind closed doors.

The brief and its addendum became publicly downloadable when the court formally filed them yesterday morning. We pulled both PDFs rather than waiting for a summary, which is how we check everything we publish.

What is Stake.us arguing on appeal?

The case is Chris Wolters v. Sweepsteaks Limited d/b/a Stake.us, No. 26-2459, on appeal from the US District Court for the District of Minnesota, No. 0:25-cv-03280, before Judge John R. Tunheim. Sweepsteaks Limited is the company behind Stake.us, and we covered the notice of appeal when the operator filed it in July. Its brief discloses a parent corporation we have not seen named in its own consumer documents: "Appellant Sweepsteaks Limited has a parent corporation, Well Done STK Limited."

The brief raises three issues. Two of them say the arbitrator should be deciding this rather than the court. The third says the opposite, and it is worth separating them, because the operator needs to win only one.

The middle one is not a delegation argument and the brief does not dress it up as one. Whether a contract was ever formed is a question courts answer themselves, and the brief quotes the Supreme Court saying so: "[t]he issue of the agreement's validity is different from the issue whether any agreement between the parties was ever concluded."

The clause it relies on is quoted in full in the brief, at section 26.6(a) of the terms Wolters accepted: "By agreeing to these Terms and Conditions, both you and Stake agree that any and all Disputes, including without limitation any question regarding the existence, validity, enforceability, or termination of these Terms and Conditions and/or this clause 26 (Dispute Resolution and Agreement to Arbitrate), shall be referred to and finally resolved by arbitration administered by the American Arbitration Association (AAA)." The same paragraph adds, in the operator's own emphasis, "you agree that you waive any right to proceed in a court of law or to have your claims heard by a jury."

Why does the brief bring up the judge's record?

Two passages say something sharper than the legal argument. On the brief's summary-of-the-case page, immediately before it asks for oral argument: "Four previous times, the Court has reversed this district court judge for denying motions to compel arbitration. The Court should do so again." The argument section opens on the same note and names them: "In four prior appeals, this Court has reversed the same district court judge for erroneously denying motions to compel arbitration", citing Bailey v. Ameriquest Mortgage (2003), McLeod v. General Mills (2017), Parm v. Bluestem Brands (2018) and Benchmark Insurance v. SUNZ Insurance (2022). From Bailey it quotes the Eighth Circuit saying that judge's "analysis reflects an outmoded judicial hostility to arbitration that the Supreme Court has consistently rejected."

That is an unusually direct thing to put in front of an appellate panel, and it tells you how the operator is framing the loss: not as a hard question about sweepstakes casinos, but as a judge who keeps getting arbitration wrong.

What did the Minnesota judge actually decide?

Stake.us attached the July 1 order to its own addendum, so the losing decision is now published alongside the appeal. We read that order in full in August, and the addendum copy matches. The court gave two independent grounds.

First, "Minnesota prohibits gambling activities like those Wolters alleges that Stake operates; and under Minnesota law, contracts entered into in contravention of state statute are void." The judge accepted that arbitration clauses are normally severable from a void contract, but found that this one is not, because it "expressly depends on the validity of the rest of the contract" through the words "By agreeing to these Terms and Conditions, both you and Stake agree" to arbitrate.

Second, the court held Stake.us "failed to establish that Wolters ever agreed to a contract of any kind", because the evidence was "only an affidavit from its founder, and an ambiguous screenshot that does not contain Wolters's name or any other relevant information."

Stake.us answers both. On severability, its brief points out that the contract in the controlling Supreme Court case, Buckeye Check Cashing v. Cardegna, likewise began "By signing this Agreement, you agree", and that its own counsel raised the point at oral argument but "the court did not address that fact in its decision". On formation, it leans on the sworn declaration of Edward Craven, whom the district court's order describes as Stake's founder, that no user can reach the platform without ticking the box, and on a concession by the player's own counsel at oral argument: Wolters "does not necessarily dispute whether he signed the contract."

Proof of acceptance is the pivot the whole category turns on. A Georgia judge sent a Chumba Casino and LuckyLand Slots class action into arbitration on the same July 1, and there the operator could show the player had accepted its terms.

What does this mean for a Stake.us player right now?

Nothing changes today. No court has found Stake.us or Sweepsteaks Limited liable for anything, the appeal decides where the dispute is heard rather than who wins it, and the allegations in the complaint remain allegations. By the operator's own account of the record, Wolters opened his account on November 25, 2022 and used Stake.us through April 2025, and he filed suit on August 15, 2025. The brief describes his complaint as five causes of action under Minnesota law: the loss-recovery statute, Minn. Stat. § 541.20, which is the same 1905 provision behind the two Minnesota class actions against Chumba Casino's owner VGW, three consumer protection statutes, Minn. Stat. §§ 325F.69, 325D.44 and 325F.67, and unjust enrichment. Stake.us states that Wolters alleges the amount in controversy exceeds the $5 million federal class-action threshold.

What it does affect is the value of the arbitration clause sitting in your own account terms. Almost every sweepstakes casino runs one, and the 30-day window to opt out of it is the single most useful clause most players never read. The clause runs both ways: in Illinois the same operator has used a finished arbitration to sue one of its own players for the award.

Readers in Minnesota should check the state page for where the law itself stands, and our guide to sweepstakes casino legality explains why "no state ban" and "lawful" are not the same sentence.
