A bet365 lawsuit today can mean several different things: New Jersey regulatory orders that returned money to underpaid bettors, a federal intellectual property suit brought by Major League Baseball players, a wave of California class actions accusing the operator of running an unlicensed gambling platform, individual gambling-addiction claims, and a string of foreign court rulings — in Spain, Germany, and Australia — that have opened doors for customers who were restricted, took losses under invalid licenses, or were misled by promotions. Which one matters to you depends on where you played, when, and what happened to your account.
New Jersey Regulators Have Already Ordered Refunds
If you placed sports bets on bet365 in New Jersey between late 2020 and early 2023, two separate 2024 enforcement actions may be relevant.
In July 2024, the New Jersey Division of Gaming Enforcement (NJDGE) ordered bet365 to refund more than $519,000 to 199 customers whose winning bets had been underpaid between December 2020 and November 2022. The operator had changed the odds on events after customers had already placed and won their bets, then paid out at the lower revised odds without seeking the required NJDGE authorization to alter wagers.1CDC Gaming Reports. New Jersey Regulator Makes Bet365 Pay $519,000 to Customers Over Odds Change Interim director Mary Jo Flaherty called it “a prolonged and unacceptable course of conduct” involving “multiple and serious violations.”2The Hill. Bet365 Ordered to Refund $519K to Customers Bet365 was given ten days to pay and did not contest the order.
Then, on August 29, 2024, the NJDGE fined bet365 an additional $33,000 for accepting over $257,700 in wagers on events whose outcomes had already been determined between February 2022 and January 2023.3Pechanga.net.

The California Class Actions
The most active consumer litigation directly targeting bet365 in the United States is happening in California. The law firm Weitz & Luxenberg has been filing waves of class-action suits since July 2025 against sportsbook and daily fantasy sports operators — including bet365, DraftKings, FanDuel, PrizePicks, Underdog Fantasy, and Thrillzz — alleging they are running unlicensed and illegal gambling platforms while advertising themselves as legal.5Weitz & Luxenberg. Daily Fantasy Sports Online Gambling Lawsuit
The theory: the underlying user contracts are void because the services themselves are illegal in California, and customers were defrauded when the companies represented otherwise. Anyone who used one of these platforms while physically located in California at any point since July 2022 may qualify.5Weitz & Luxenberg. Daily Fantasy Sports Online Gambling Lawsuit Case numbers and procedural details specific to bet365 have not been publicly disclosed.
Gambling Addiction Lawsuits Against bet365
Bet365 is one of several operators — alongside DraftKings, FanDuel, Caesars, and BetMGM — being reviewed by plaintiffs’ attorneys for claims brought by users who developed a diagnosed gambling disorder after using the app. These are individual lawsuits rather than class actions, generally handled on contingency, and firms commonly require documented losses or debt of at least $10,000 before taking a case.6TruLaw. Bet365 Lawsuit for Gambling Addiction
The claims typically rest on three theories. Product liability treats the app itself as a defective product engineered for compulsive use. Negligence alleges failure to protect users showing signs of addiction. Consumer protection claims argue that promotions labeled “risk-free” or “no sweat” are misleading. Plaintiffs point to algorithms and behavioral targeting that push bonuses and notifications at high-risk moments, like late at night or right after a loss.7ESPN. Lawsuit Accuses Sportsbooks of Using Addictive Technology
Courts have historically been unfriendly to these claims, holding that sportsbooks are not responsible for monitoring customer habits. That is starting to shift. In March 2026, a federal judge in Illinois allowed a product-liability class action against DraftKings to proceed, rejecting the company’s argument that a betting app does not qualify as a “product.”7ESPN. Lawsuit Accuses Sportsbooks of Using Addictive Technology Whether that reasoning carries over to bet365 in future cases is not yet settled.
Spanish Rulings on Restricted and Closed Winning Accounts
If bet365 restricted your stakes, capped your winnings, or closed your account after a winning run, Spanish courts have repeatedly ruled that the contract clauses used to justify those actions are unenforceable.
In August 2019, a Madrid court sided with eight bettors from Caravaca de la Cruz who had been sharing picks by WhatsApp and winning 500 to 2,000 euros a week each. Bet365 had cut their stakes to as little as 2 or 3 euros per event or closed their accounts. Judge Gladys López Manzanares declared three contract clauses null and void as abusive under Spanish consumer protection law, finding they allowed arbitrary operator action without cause or any consumer right of reply.8ArbUsers. Bet365 Ordered to Restore Account Limits
In July 2021, courts in Oviedo ordered both bet365 and Betfair to reactivate suspended accounts without limits and ruled that operators could no longer force users to accept general subscription conditions that included account-limiting clauses.9Yogonet. Spain Courts Rule Against Betfair and Bet36510Legal Sports Report. What Happens When Sportsbooks Cannot Limit In May 2025, the Provincial Court of Huesca partially ruled against bet365 in a case brought by a user named Marcial, declaring a clause that let the operator reject bets after confirmation null and void because it created a “significant imbalance to the detriment of the consumer.” The court ordered unjustified restrictions on the plaintiff’s account lifted, though it upheld bet365’s right to terminate accounts with proper notice.11MundoVideo.

German Players May Be Able to Reclaim Losses
On June 27, 2024, the German Federal Court of Justice (BGH) ruled that players can reclaim gambling losses from operators who offered services in Germany without a valid German license. The court held that contracts formed in violation of statutory gambling prohibitions are void under the German Civil Code.12Oracle Law Global. Illegal Online Gambling in Germany: When Players Have a Right to a Refund
The timing matters. Sports betting operators could not obtain German licenses until October 2020, and online casino licenses were not available until October 2022. Losses on bet365 and other platforms operating under foreign licenses — such as Malta Gaming Authority credentials — before those dates may be recoverable. Players who learned of their rights through the June 2024 ruling may have until the end of 2027 to file under the three-year statute of limitations.12Oracle Law Global. Illegal Online Gambling in Germany: When Players Have a Right to a Refund
One caveat: the BGH suspended one of its own appeal proceedings in January 2024 to await a Court of Justice of the European Union ruling on whether Germany’s earlier total ban on online poker and slots is compatible with EU law. Many lower courts have paused similar refund cases pending that decision.13Taylor Wessing. Update on Player Refund Claims
The MLB Players Likeness Suit
This one doesn’t put money in customers’ pockets, but it’s an active federal case naming bet365. On September 16, 2024, MLB Players, Inc. (MLBPI), the licensing arm of the Major League Baseball Players Association, sued DraftKings and bet365 Group Limited in the U.S. District Court for the Eastern District of Pennsylvania. The complaint alleges the sportsbooks used the names, images, and likenesses of hundreds of active MLB players — headshots and action shots tied to prop bets — without authorization or a license.14FindLaw. MLB Players Inc. v. DraftKings, Inc.15CCH. MLB Players Inc. v. DraftKings Complaint
The suit brings claims under a Pennsylvania publicity-rights statute plus common-law misappropriation of publicity, misappropriation of identity, and unjust enrichment. On March 17, 2025, Judge Karen Marston denied the defendants’ motions to dismiss the core claims, finding MLBPI has standing as the assignee of the players’ publicity rights and rejecting the argument that pairing player images with betting odds is protected news reporting. Content that serves an advertising purpose, she held, remains subject to publicity-rights laws.14FindLaw. MLB Players Inc. v. DraftKings, Inc. In May 2025, Marston denied DraftKings’ bid to pursue a midstream appeal.16Bloomberg Law.

The Australian Ruling on Misleading Promotions
If you signed up for a bet365 free-bet offer years ago in Australia, a court has already found that specific promotion misleading. In September 2015, the Federal Court of Australia ruled on an Australian Competition and Consumer Commission (ACCC) case involving bet365’s “$200 FREE BETS FOR NEW CUSTOMERS” promotion, which ran between March 2013 and January 2014. The court found the offer misleading and deceptive because customers had to gamble their deposit and bonus three times before withdrawing anything. A customer depositing $200 and receiving a $200 bonus had to wager $1,200 before touching any money.18ACCC. Court Finds Bet365 Engaged in Misleading and Deceptive Conduct
Justice Beach wrote that customers, including inexperienced gamblers, were “drawn into this web of deception.” The ultimate holding company, Bet365 Group Limited, was cleared, and the operator prevailed on some other ACCC allegations.18ACCC. Court Finds Bet365 Engaged in Misleading and Deceptive Conduct
The Arbitration Problem
Before pursuing any U.S. claim against bet365 as an individual, know this: like most online sportsbooks, bet365 requires users to agree to binding arbitration and a class-action waiver. The Arizona-facing terms, updated in November 2025, state prominently that they are “subject to binding arbitration and a waiver of class action rights.”19bet365. Terms and Conditions Some plaintiffs’ lawyers have challenged these clauses as one-sided, and some have pivoted to mass arbitration, filing thousands of individual claims at once. Public entities such as municipalities are generally not bound by these clauses, which is why cases like Baltimore’s suit against other sportsbooks proceeded in court.20ESPN.

What This Means If You Bet on bet365
The right next step depends on your situation. If you were a New Jersey customer whose winning bet was paid at reduced odds during 2020–2022, or whose bet on a Bellator, PFL, Honda Classic, college basketball, or European exhibition soccer market was later refunded, the NJDGE orders are the reason. If you played on bet365 while in California at any point since July 2022, you may fit within the Weitz & Luxenberg class actions. If you developed a diagnosed gambling disorder and have significant documented losses, individual addiction litigation is being reviewed, though it remains legally uncertain. If your account was restricted or closed after winning in Spain, or you lost money on bet365 in Germany before it held a valid German license, foreign court rulings have created concrete refund paths. And if you’re a U.S. customer thinking about suing individually, the arbitration clause in your account terms will shape almost everything about what you can do next.
