Sleeper’s terms of service include a mandatory arbitration clause that prohibits users from joining class action lawsuits—a provision that became the center of a class action lawsuit filed in federal court. In October 2025, Holyk v. Blitz Studios, Inc. (Case No. 3:25-cv-02606) was filed in the U.S.
District Court for the Southern District of California, challenging Sleeper’s business practices and the enforceability of its arbitration requirements. The case alleged that Blitz Studios, which operates the Sleeper fantasy sports app, was running an illegal gambling platform disguised as daily fantasy sports while simultaneously preventing users from seeking relief through collective legal action. The lawsuit centers on a critical question: Can a company legally prevent users from joining class actions when the company itself may be breaking the law? Sleeper’s terms explicitly include a 30-day opt-out arbitration clause that strips users of their right to participate in class lawsuits. However, when the underlying business model itself is challenged as illegal—as happened when California’s Attorney General declared all daily fantasy sports contests illegal gambling in July 2025—that arbitration clause comes under intense legal scrutiny. For users of Sleeper during the period covered by the lawsuit, understanding the implications of these terms became crucial to knowing what legal options remained available.

What Sleeper’s Arbitration Clause Actually Says and Why It Matters
Sleeper’s terms of service contain language requiring all disputes to be resolved through binding arbitration rather than through the court system. This means that instead of filing a lawsuit, users are required to submit claims to a private arbitrator—a neutral third party who decides the case. The 30-day opt-out provision gives users a limited window to reject this clause, but most users never opt out because they don’t read the fine print or don’t understand the implications. If a user doesn’t opt out within 30 days of agreeing to the terms, they are locked into arbitration for any future disputes.
The problem with arbitration for consumers is that it severely limits legal remedies and makes class actions essentially impossible. In a class action, thousands or tens of thousands of people combine their small individual claims into one large lawsuit, which makes it economically worthwhile for lawyers to take the case. In arbitration, each person must pursue their claim individually, which means most users—faced with the high cost of hiring a lawyer for a small dispute—simply give up. For Sleeper users, this clause was particularly problematic because it prevented them from banding together to challenge the legality of the platform itself. The arbitration requirement meant that even if a user believed Sleeper was operating an illegal gambling service, they couldn’t join a class action to seek a refund of all money wagered on the platform.
The California Attorney General’s Declaration and How It Changed Everything
In July 2025, California’s Attorney General Rob Bonta issued a legal opinion that fundamentally shifted the landscape for fantasy sports operators in the state. The opinion declared that all daily fantasy sports—including pick’em-style contests and peer-to-peer competitions—constitute illegal gambling under California law. This wasn’t a new law; it was a clarification of existing law. The AG’s position was that fantasy sports operators had been skirting California’s gambling statutes, and their business models needed to be brought into compliance or shut down.
Sleeper’s Pick’em contests were specifically designed in a way that appeared to fit the legal definition of daily fantasy sports. However, the AG’s opinion put the company on notice: the contests Sleeper offered, where users wagered on individual athlete performances, crossed the line from legal fantasy gaming into illegal gambling. This legal declaration created the foundation for the Holyk class action. The lawsuit alleged that Sleeper had falsely marketed these contests as legal in California and had knowingly operated in violation of state gambling law. Once the class action was filed on October 2, 2025, the question of whether Sleeper’s arbitration clause could shield the company from litigation became unavoidable.
The Allegations Against Blitz Studios and Sleeper’s Business Model
The Holyk complaint characterized Sleeper not as a fantasy sports platform but as an illegal sports betting operation. According to the lawsuit, Blitz Studios—the company behind Sleeper—was disguising straightforward gambling bets as daily fantasy sports contests to circumvent California law. The distinction is important: California permits some forms of fantasy sports under specific conditions, but it prohibits any game where wagering on individual athlete performance is the primary mechanism. Sleeper’s contests allowed users to enter Pick’em competitions where they made predictions about individual players’ performance metrics and stood to win money based on those predictions.
This structure, the lawsuit argued, was functionally identical to sports betting and violated California Penal Code Section 330. In addition to the core allegation about illegal gambling, the complaint also claimed that Sleeper had engaged in false marketing and misrepresentation. Users were told that the contests offered on the Sleeper platform were legal in California, when in fact the company had no legal basis for making that claim. Sleeper’s marketing materials and terms didn’t explicitly address the legality question, but by continuing to operate and accept users from California without warning them that the AG had declared DFS illegal, the company’s silence functioned as an affirmative misrepresentation. Users believed they were participating in a legitimate fantasy sports platform when, according to the lawsuit, they were actually participating in an unlicensed gambling operation.
How the Class Action Was Structured and Who Played Key Roles
The Holyk case was brought on behalf of all users of Sleeper’s Pick’em contests during the relevant time period—essentially anyone who had wagered money on those contests and lost. The plaintiff attorney was Edelsberg Law, a firm with experience in class actions against tech platforms and gaming companies. This case was significant because it wasn’t filed by state gambling regulators or law enforcement; instead, it was filed by an individual user (Holyk) whose claim was aggregated into a potential class action that could have affected thousands of other users who felt they had been deceived or had lost money on what they believed to be a legal platform. The case was filed in the U.S.
District Court for the Southern District of California, which has jurisdiction over federal claims and claims arising from transactions in California. This venue choice was strategic because California’s courts have consistently been skeptical of arbitration clauses when they’re used to prevent consumers from challenging unlawful conduct. The comparison to other DFS litigation in California is instructive: as of the filing date, California had at least 8 class actions pending against leading DFS platforms. This wasn’t a lone complaint—it was part of a wave of litigation responding to the Attorney General’s July 2025 opinion. That coordination of lawsuits created leverage: if Holyk succeeded in establishing that DFS was illegal in California, other cases would follow the same legal roadmap.
The Arbitration Clause Problem and Why It Might Not Hold Up
One of the central legal battles in the Holyk case was whether Sleeper’s arbitration clause could prevent the lawsuit from proceeding as a class action. Sleeper argued that because every user had agreed to the terms, they were bound by the arbitration clause and the case should be dismissed. However, there’s an important exception to arbitration clauses: they cannot be enforced to shield a company from liability for illegal conduct. If Sleeper was indeed operating an illegal gambling operation in violation of California law, the arbitration clause might be unenforceable as a matter of public policy.
California courts have repeatedly held that companies cannot use contractual provisions to insulate themselves from the consequences of breaking the law. The critical limitation here is that even if users wanted to opt out of the arbitration clause, they could only do so within 30 days of accepting the terms. Any user who discovered the issues later—perhaps after learning about the AG’s opinion in July 2025 or after seeing news coverage of the lawsuit—was locked in. This is why many class action lawsuits challenge arbitration clauses as procedurally unconscionable (the process was unfair because the user had no meaningful choice) or substantively unconscionable (the terms are so one-sided that they shock the conscience). Sleeper’s 30-day opt-out window, combined with the fact that users likely didn’t understand the implications when they agreed to the terms, created exactly this type of vulnerability.
The Broader Market Context and What Was at Stake
Despite the legal troubles, Sleeper and other DFS platforms remained operational in California because it is the largest daily fantasy sports market in the United States. No DFS operator has voluntarily exited the California market, even as lawsuits accumulated. This created a situation where the law—as declared by the Attorney General—and the market practice—companies continuing to operate—were in direct conflict. The Holyk case was part of the legal mechanism by which that conflict would eventually be resolved.
If Sleeper lost the case, it could face liability for refunds to all users who wagered on Pick’em contests, plus potential damages for fraud or misrepresentation. The implications extended beyond Sleeper. The case was one of at least 8 class actions pending against leading DFS platforms in California. Each of these cases had the potential to establish precedent about whether the AG’s opinion would be upheld by courts, whether arbitration clauses could block collective relief, and whether companies that continued operating after the AG’s declaration could be held liable. For users, the important point was that the legal landscape had become genuinely uncertain—what was marketed as legal might turn out to be illegal, and anyone who had wagered money on these platforms might eventually be entitled to compensation.
Case Status and What Happened Next
On January 14, 2026, the Holyk case was terminated. The specific reasons for termination—whether the case was settled, dismissed, or resolved through some other mechanism—are important details for users to understand, though the public record may contain different levels of detail. Termination of a case before trial can result from a settlement agreement, in which case users might receive compensation; a motion to dismiss, in which case the lawsuit ends without recovery; or other procedural developments.
The timing of the termination, less than three months after the case was filed, suggests the matter may have been resolved relatively quickly—though whether that was favorable to users or favorable to Sleeper depends on the terms of any settlement or dismissal. The broader question moving forward is what this case established for other DFS litigation in California. The case law precedent from Holyk, whether published or not, would inform the other 8 pending class actions against DFS operators. Users who participated in Sleeper’s Pick’em contests during the period covered by the lawsuit should check whether they were included in any settlement agreement or should determine whether other class actions—naming different defendants but covering similar conduct—might apply to their situation.
Conclusion
The Sleeper Fantasy App class action raised critical questions about the enforceability of arbitration clauses when a company’s underlying business model may be illegal. Sleeper’s terms required users to submit disputes to arbitration rather than participating in class actions, but when the California Attorney General declared all daily fantasy sports illegal in July 2025, that arbitration clause came under pressure. The lawsuit alleged that Blitz Studios operated Sleeper as an unlicensed gambling operation disguised as fantasy sports and that users had been misled about the legality of their wagering. Filed on October 2, 2025, in the U.S.
District Court for the Southern District of California by Edelsberg Law, the case was terminated on January 14, 2026. For users of Sleeper during the relevant period, understanding this case matters because it establishes that arbitration clauses may not protect companies from class action liability when the underlying conduct is illegal. If you wagered on Sleeper’s Pick’em contests before the case was terminated, check whether you were included in any settlement or whether other DFS class actions might cover your losses. The legal landscape for daily fantasy sports in California remains in flux, with at least 8 class actions pending against leading operators, all building on the foundation of the Attorney General’s determination that DFS constitutes illegal gambling under state law.
