Modo.us Arbitration Award: Player Loses All Four Claims

A JAMS arbitrator entered a Final Award for Modo.us operator ARB Gaming on September 4, 2026, ending a player's arbitration on all four claims he had left. The 36-page award reached a public federal docket on September 16, which is why anyone can now read what one of these sweepstakes arbitrations actually produces. Not one of the claims was decided on its merits. The player lost because he started the arbitration himself, and then could not get out of it.

The award was filed as Exhibit A to Defendant ARB Gaming LLC's Notice of Final Arbitration Award in Its Favor, entry 115 in Joyce v. ARB Gaming LLC, No. 2:25-cv-01868-DJC-CSK (PS), in the Eastern District of California. We downloaded all three documents in that entry straight from the federal record and read the award end to end, which is how we check everything we publish. Modo.us is run by ARB Gaming, LLC and has never been one of our ranked brands: it sits on our list of sweepstakes casinos to avoid over the Arizona Department of Gaming action and the Illinois cease-and-desist wave.

This matters beyond one player because the same clause is in almost every rulebook in this market. We have written about the orders sending Modo.us players to arbitration and about the 30-day opt-out window that runs across nine unrelated brands. Until now we could only describe the door. This is the first time we have been able to read what is on the other side of it.

What did the arbitrator actually decide?

That ARB Gaming wins, on all four surviving claims, without a hearing on the merits of any of them.

The arbitrator was the Hon. Peggy A. Leen (Ret.), sitting in JAMS case reference no. 5100003080. Her Final Award incorporates an Interim Award of May 13, 2026 and an order of March 4, 2026, and it disposes of the claims Matthew Joyce brought for breach of contract, unjust enrichment, negligent misrepresentation and fraud or intentional misrepresentation. His California statutory claims had already gone, dismissed with prejudice.

The arbitrator's own words on the turn that decided it: "having initiated this arbitration, and requested arbitral resolution of multiple issues, including whether the parties' arbitration agreement is binding and enforceable", Joyce "has invoked the jurisdiction of this arbitral forum and has waived any argument his remaining claims should not be arbitrated."

Can a player walk away once arbitration has started?

No, and this is the part that should change how a reader thinks about the clause.

Joyce tried twice. In April 2026 he filed a Notice of Withdrawal of All Claims and asked for dismissal without prejudice. The award holds that Rule 13(a) of the JAMS rules the contract selects "prohibits a party from terminating or withdrawing from an arbitration after the issuance of the commencement letter 'except by written agreement of all Parties to the Arbitration.'" ARB did not agree in writing, and the arbitrator found that letting him go "would prejudice Respondent by depriving it of this arbitrable forum".

In August he tried again, asking either to terminate the proceeding or, failing that, for a Final Award embodying what had already been decided. He got the second option. ARB had filed a motion to dismiss on July 3 which Joyce never opposed, and the arbitrator read the two things together: she construed "Claimant's failure to respond to the motion to dismiss and motion to terminate or in the alternative, request for entry of a final award as yet another attempt to withdraw all of his claims against Respondent in this arbitration and a consent to entry of a Final Award in favor of Respondent."

That is worth pausing on, because it is the mechanism. He was not held to have lost an argument. He was held to have consented, by not filing anything.

Two more details from the award matter. His first lawyer prepared and filed the Demand for Arbitration that bound him, and he was then left without counsel twice over. The arbitrator's own procedural record shows his first counsel failed to appear at the oral argument set for November 13, 2025, and ARB's own filings refer to her having been disbarred; Joyce's sworn declaration adds that he learned the day after that hearing that she had been disbarred from federal practice in the Northern District of California, and that he was "acutely ill" through that period. His second counsel's withdrawal was granted on June 18, 2026. He argued everything after that himself.

Why did the California consumer claims die first?

Because the contract chose Arizona law, and the arbitrator enforced that choice.

Joyce, whom the award identifies as a North Carolina resident who "occasionally accessed the Modo platform in 2024 and 2025", brought claims under California's Unruh Civil Rights Act, California's unfair business practices statute and the California Financial Lenders Law. The clause he had accepted said "These Terms and all matters arising out of, or relating to, these Terms shall be governed by the laws of the State of Arizona" - it reached the claims, not just the arbitration. The arbitrator held that "the governing law provision of the parties' arbitration agreement is mandatory, valid and enforceable", that Arizona law applies, and that his "conclusory jurisdictional allegations do not support jurisdiction, venue or a legally cognizable claim under California law". Those three counts were dismissed with prejudice, meaning they cannot be refiled.

This is the part with the widest reach. A governing-law line most players never read decided which state's consumer statutes were available to him, and the answer was: not the ones where he was sitting.

The argument that the whole contract was void because the underlying business is illegal did not get him past the clause either. Under the separability rule from Prima Paint and Buckeye Check Cashing, the arbitrator found the agreement to arbitrate "severable from the contract as a whole, mandatory, binding and enforceable under the FAA". The version of the Terms in front of her said so in terms: the arbitration agreement "is a separate agreement between the parties and that any alleged or determined invalidity or illegality of all or part of the Terms or Platform shall have no effect upon the validity and enforceability of this agreement."

For the record, the amounts. ARB's motion to dismiss, as the arbitrator summarises it, refers to "Claimant's demand for $10.5 Million in damages". Joyce's own complaint alleged at paragraph 41 that he was allowed to win "$6,000 on Defendants' platform but was later coerced into signing a terms and conditions page under duress". None of that was tested. ARB's position throughout was that "the games it offers do not offer real gambling opportunities, no money is required to play and the products do not constitute gambling." That is the defence most of this industry runs on, and our guide to sweepstakes casino legality state by state sets out how differently the states answer it.

What do Modo's arbitration terms say now?

Not what they said when Joyce signed. We pulled the Terms of Use that modo.us publishes as a PDF, and the live document is dated August 20, 2026 and states that it "shall supersede and replace all prior Terms of Use". The arbitration agreement has moved from Section H to Section 22 and has been rebuilt.

Read that mass-claims row carefully, because it is narrower than it looks. It bites only when the demands are "presented by or with the assistance of the same law firm or organization or group of law firms or organizations working in coordination". Twenty unconnected players filing the same week do not trigger it. What it does is slow a coordinated campaign down: a first batch of no more than 25, then a compulsory mediation of everything left, then batches of up to 100.

Two further provisions in the live text are worth reading before you agree to them. The user's share of arbitration fees is capped: "You will only be required to pay arbitration fees of $250", though you still pay your own lawyer. And either side can appeal, under the JAMS Optional Arbitration Appeal Procedures, any award "in excess of $50,000 in favor of either party" or any award granting "declaratory or equitable relief that would significantly impact other Modo users or the operation of the Platform" - a route that in practice matters more to the operator than to a single player, because it is the operator that faces the second kind of award.

The confidentiality clause deserves its own paragraph, because it is the reason awards like this are normally invisible and it is also the reason this one is not. Section 22.10.9 makes "the arbitration proceeding, pleadings, and any award" confidential, but not absolutely: it excepts use "in connection with a court application for a preliminary remedy, a judicial challenge to an award or its confirmation and enforcement". ARB filed the award to support its pending motion to compel and says it expects to move to confirm the award. That is squarely inside the carve-out. Nobody waived anything here. The clause simply means a player only ever sees one of these when an operator wants a judge to look at it.

One clause is conspicuously absent. When a federal judge in Massachusetts held on September 14 that Modo's Terms never formed a contract at all, she quoted an amendment provision under which changes were "enforceable immediately upon posting" and a revised version "immediately and retroactively supersedes any prior versions". We searched the live PDF for both phrases and for "retroactively supersede" and "enforceable immediately" on their own. None of them appears anywhere in the document Modo publishes today. The live amendment clause still lets the company change the Terms unilaterally, but it no longer carries the wording that decided that case. We are reporting the difference, not a reason for it. Unilateral amendment is the market norm rather than the exception: five of the six rulebooks we compared can be rewritten without telling the player.

Which other companies are named in the court case?

The federal caption is wider than the arbitration. Alongside ARB Gaming it names B2Services OU doing business as McLuck, together with Affirm, Goldman Sachs Bank USA, Apple and Amazon.com.

Nothing in the arbitration decided anything against any of them, and the record is explicit about why. "The Demand does not name anyone other than ARB Gaming as a Respondent." Joyce's first lawyer told the preliminary hearing on September 25, 2025 that she had not served, did not intend to serve and was not pursuing claims against the other two entities named in the attached complaint, and the Interim Award dismissed those claims with prejudice. In the federal case, Affirm's and Apple's motions to dismiss and Goldman Sachs Bank USA's motion to compel were all fully briefed and still undecided when we read the docket on September 17; nothing on the file records a motion from Amazon.com. McLuck is a ranked brand on this site and part of the B-Two Operations family; being named in a caption is not a finding against it, and we have not seen one.

How do I opt out of Modo.us arbitration?

The opt-out window is the only lever you get, and it closes 30 days after you sign up.

That is the practical lesson of a 36-page award in which the merits were never reached. Once a dispute is inside arbitration it is very hard to get out, and the governing-law clause can delete the consumer statutes of the state you were sitting in.

So here is the concrete version, for Modo specifically, because vague advice is no advice. If you opened a Modo account in the last 30 days and want to keep your right to sue:

1. Write a notice headed "OPT-OUT", giving your full name and the email address on your account.
2. Post it to ARB Gaming LLC, Attn: Arbitration Opt-Out, at the Scottsdale, Arizona address set out in Section 22.14 of the live Terms.
3. Send it inside 30 days of accepting the Terms. The document says in capitals that a later request "SHALL NOT BE EFFECTIVE".
4. Check first that this is your first Modo arbitration agreement. The clause only offers the opt-out "IF YOU HAVE NOT PREVIOUSLY AGREED TO AN ARBITRATION PROVISION IN CONNECTION WITH YOUR USE OF OUR SERVICE", so a returning player who accepted an earlier version has nothing to opt out of.

If you opened your account earlier than 30 days ago, that window has already shut and nothing in this award reopens it; what you have left is the small-claims carve-out in Section 22.3 and, once you are in arbitration, a $250 cap on your share of the fees. At every other sweeps site, read the dispute section on the day you register, not the day you have a problem. Our guide to how sweepstakes casinos work covers what you are actually agreeing to, and the brands we do rank, with paperwork we can follow, are on our ranked list of sweepstakes casinos.

ARB's filing says it "anticipate[s] separately moving for an order confirming the Final Award in due course". If it does, that is the same route another operator took when Stake.us went to federal court to enforce an award against one of its own players.
