Gaming Edge’s TL;DR

  • Two recent lawsuits accuse FanDuel and DraftKings of designing apps that push micro-betting and addictive behavior.
  • The claims, filed in Pennsylvania and Massachusetts, allege the companies used data-driven targeting – notifications, ads, and in-app prompts – to coax users into repeated, high-frequency wagers, raising questions about product design, league partnerships, and player protections.

Two lawsuits – one in Pennsylvania and another in Massachusetts – were filed last week against FanDuel, DraftKings, and related parties.

The Massachusetts suit, brought by Daniel Arroyo, says targeted ads and push notifications led him to lose roughly $160,000 on FanDuel and $20,000 on DraftKings, forcing him into therapy and leaving his job. It asserts seven counts, including negligence and intentional misrepresentation.

The Pennsylvania complaint, filed by Christopher Sage and Terry Thompson, alleges the platforms use artificial intelligence and behavioral analytics to steer customers to micro-betting. Sage claims losses of $130,000 on FanDuel and $40,000 on DraftKings. Thomson said he lost $1.52 million on FanDuel and $336,000 on DraftKings. That suit adds the NFL and Genius Sports for supplying real‑time data that allegedly enabled targeted promotions and includes 16 counts such as unfair trade practices and unjust enrichment.

Both cases are brought by the Public Health Advocacy Institute. FanDuel and DraftKings declined detailed comment.

Lawsuits go beyond gambling losses

These suits spotlight risks tied to in-play and micro-betting products, not just financial losses but mental health and addiction concerns tied to aggressive personalization. If plaintiffs prevail or secure settlements, operators could face large reimbursements, stricter oversight, and requirements to change app design, notification flows, marketing practices, and add more responsible gambling tools.

League and data partners like the NFL and Genius Sports could also face reputational and contractual pressure given allegations they provide the live data that powers micro-betting.

A federal judge in Pennsylvania previously limited liability for DraftKings in a separate case, showing mixed precedents. Still, parallels to tech litigation (e.g., rulings finding platforms negligent over addictive design) increase the likelihood of regulatory scrutiny, higher compliance costs, and expanded responsible gaming measures across the industry.
