Dozens of federal class actions against DraftKings, FanDuel, BetMGM, and Caesars are moving toward coordinated proceedings. Motions to dismiss have been denied, and discovery of internal addiction-targeting algorithms is underway. Cornerstone Law is reviewing cases nationwide — with no upfront cost to you.
Key Cases
Multiple federal courts have denied motions to dismiss, allowing core claims to proceed. Early discovery orders are already producing internal documents that plaintiffs are using to build their cases.
Doe v. DraftKings Inc.
Case No. 1:24-cv-11892 — District of Massachusetts
Allegations: failure to warn of addiction risks, deceptive promotional practices, and unlawful targeting of vulnerable users through behavioral data.
Smith v. FanDuel Group Inc.
Case No. 1:25-cv-00611 — Northern District of Illinois
Status: defendant's motion to dismiss partially denied — the court held that claims based on deceptive marketing and failure to implement responsible-gaming safeguards may proceed.
In re: Sports Betting Data Privacy Litigation
Case No. 3:25-cv-01477 — Northern District of California
Key argument: platforms allegedly used behavioral-tracking algorithms to identify and specifically target high-risk or already-addicted users for increased engagement.
Named Defendants
Class actions have been filed against the major online sports betting platforms operating in the United States. Each is alleged to have used addictive design features, deceptive marketing, and algorithmic targeting to drive compulsive gambling behavior.
Why These Lawsuits Are Being Filed
These claims mirror the theories used in the social media addiction MDL, but applied to gambling-behavior manipulation. Internal documents produced in discovery are already corroborating plaintiffs' core allegations.
Apps were allegedly engineered using the same dopamine-driven feedback mechanics as slot machines, designed to make users chase losses and return compulsively.
Platforms built behavioral profiles to identify users most likely to develop gambling disorders, then allegedly increased promotional outreach to those exact users.
Advertised "risk-free bets" allegedly came with hidden conditions that made them anything but risk-free, drawing in new users under false pretenses.
Platforms allegedly failed to implement meaningful safeguards, letting users continue betting despite clear behavioral signals of problem gambling.
Plaintiffs allege granular betting behavior data was collected and monetized to increase deposit frequency, session length, and micro-bet volume among high-risk users.
Social-media advertising campaigns allegedly reached users under 25, the demographic most vulnerable to developing gambling disorders, with heavy promotional incentives.
