Legal and investigative scrutiny has intensified regarding the design and impact of major US sports gambling platforms, specifically FanDuel and DraftKings.

Attorney Jennifer Hoekstra filed 15 lawsuits alleging that these platforms utilize addictive app designs. This legal action follows reports of significant financial consequences associated with legalized online sports gambling, including a UCLA study linking it to a 25% increase in bankruptcies and credit card delinquencies in certain states. While FanDuel maintains it invests heavily in responsible gaming and monitors problematic behavior, the industry faces growing concerns over the scale of problematic gambling among American adults.

Further scrutiny emerged through a ProPublica investigation into DraftKings, which alleged the platform rewards reckless betting behavior. During a 10-week experiment, a reporter mimicking compulsive gambling patterns was not flagged for intervention after significant losses; instead, the platform issued an invitation to a VIP program. The investigation highlighted a contradiction between responsible gaming prompts and promotional tactics, noting that regulatory safeguards, such as deposit notifications in New York, could be easily bypassed. Experts suggested that platform designs may prioritize profits from high-stakes players over consumer protection.
