Lawsuits accuse online sportsbook apps, chiefly DraftKings and FanDuel, of fueling gambling addiction. Plaintiffs allege addictive app design and promotions aimed at vulnerable users led to large financial losses, job loss and suicidal ideation.
Separate individual, class action and city lawsuits are pending in state and federal courts. No MDL, settlement or verdict exists. The newest, filed September 30, 2026, is a proposed class action in Boston. DraftKings denies the allegations.
These are allegations, and no court has found liability in any of them. The plaintiffs include individual bettors, proposed classes and the City of Baltimore, which sued in April 2025.
Latest Sports Betting Lawsuit Updates
September 30, 2026: Proposed Class Action Targets DraftKings AI Use
Boston.com reported that West Virginia plaintiff Daniel Vest filed a proposed class action against DraftKings in the U.S. District Court in Boston. The suit alleges the company used artificial intelligence to target vulnerable gamblers with promotions [1].
Vest asks the court to award damages to the class, issue refunds and stop DraftKings from using the AI. A DraftKings spokesperson said the company does not use AI to target customers based on losses.
September 24, 2026: Massachusetts Regulator Reviews Sportsbook AI Use
Quartz reported that the Massachusetts Gaming Commission said it would examine how DraftKings and other licensed sportsbooks use artificial intelligence. The review followed a New York Times investigation [2].
The commission has not determined that DraftKings committed any wrongdoing. DraftKings says it vehemently denies doing anything to make its offerings addictive.
April 9, 2026: Pennsylvania Court Lets Risk-Free Bet Claims Proceed
Courthouse News reported that a federal court in Pennsylvania allowed gamblers to pursue deceptive advertising claims against DraftKings over its “risk-free bet” promotion [3].
The gamblers plausibly alleged they were misled. They say they expected cash refunds, not non-withdrawable credits, when they lost their bets. The ruling lets the claims proceed. It is not a finding of liability.
March 24, 2026: Sage and Thompson File Microbetting Suit
Sportico reported that Christopher Sage and Terry Thompson filed Sage & Thompson v. DraftKings et al. in the Philadelphia County Court of Common Pleas. The defendants include DraftKings, FanDuel, the NFL, Genius Sports and others [4].
The complaint accuses the companies of negligence, design defect, failure to warn, unfair trade practices and related claims. These are allegations.
March 20, 2026: Fourth Circuit Asked to Return Baltimore Case to Federal Court
A Law360 report on the Fourth Circuit filing said DraftKings and FanDuel urged the court to send Baltimore’s deceptive practices lawsuit back to federal court [5].
They argued that the narrow exceptions allowing a district court to decline the lawsuit were not met in this case. The request followed a federal judge’s remand of the suit to state court.
November 10, 2025: Judge Sends Baltimore Case Back to State Court
Judge Stephanie Gallagher sent Baltimore’s lawsuit against DraftKings and FanDuel back to Baltimore City Circuit Court, The Daily Record reported [6].
The order came on November 10, 2025. The city first sued in that state court in April 2025, so the case now returns there.
April 21, 2025: Pennsylvania Class Action Targets DraftKings
Law360’s Pennsylvania report described a proposed class action naming DraftKings and a subsidiary. It alleges deceptive practices, including knowingly targeting people suffering from gambling addiction [7].
The suit also alleges the companies let people on Pennsylvania’s self-exclusion gambling list open new accounts. The case is in federal court in Pennsylvania.
April 3, 2025: Baltimore Sues DraftKings and FanDuel
The Washington Post reported that the City of Baltimore sued DraftKings and FanDuel in Baltimore City Circuit Court. The city accuses them of unfair and deceptive practices under state and city law [8].
The complaint alleges misleading promotions that lure people in, then data used to find users least able to resist continued gambling. FanDuel says it does not comment on specific allegations in pending litigation.
What Is Sports Betting Addiction?
According to the World Health Organization, gambling disorder is described alongside substance use disorders in both the DSM-5 and ICD-11. WHO estimates that 1.2% of the world’s adult population has a gambling disorder [9].
The sports betting lawsuits describe harm of this kind from app-based wagering. They allege app design and promotions helped fuel it.
Who May Be Affected?
People who bet on DraftKings or FanDuel apps and allege the apps’ design or promotions fed a gambling disorder may be affected.
Sage and Thompson, two Pennsylvania men, point to rapid in-play microbetting. Vest, a West Virginia plaintiff, points to at least 70 promotional emails, texts or alerts in the month before September 25, 2026.
An Illinois man alleges DraftKings made him a VIP and gave him benefits to increase his betting. The Pennsylvania class action points to accounts opened by people on the state self-exclusion list.
These are plaintiffs’ allegations, not eligibility rules, and only an individual legal review can say whether a claim fits your situation.
Reported Injuries or Damages
Plaintiffs allege addiction, heavy debt, lost jobs and suicidal ideation after betting on apps. These allegations are in complaints and have not been tested in court.
Forbes reported that Dane Miller, 32, of Illinois sued DraftKings in June 2026. He alleges DraftKings’s analytical tools increased his addiction risk and that he placed more than $2 million in wagers [10].
Miller alleges the betting drained loans, credit cards, a 401(k) and his wedding fund, and that he lost his job. He says he was hospitalized with suicidal ideation in October 2024 and diagnosed with severe gambling disorder.
In the Sage and Thompson complaint, Sage alleges net losses of about $175,000 after wagering a little over $2 million. The World Health Organization says gambling can lead to financial stress, relationship breakdown, family violence, mental illness and suicide.
Baltimore’s complaint cites Maryland Center of Excellence on Problem Gambling. They put disordered gambling at 20.8 percent of online sports bettors, 11.3 percent of traditional sports bettors and three percent of non-bettors.
It also cites a study finding over 30 percent of problem gamblers report suicidal ideation. These are the city’s cited figures and do not reflect a court finding.
Evidence to Preserve
The complaints describe app activity, promotions, losses and treatment. Records that match those details may matter:
- Account statements and deposit and withdrawal history
- Screenshots of the app, bonus offers and “risk-free bet” promotions
- Promotional emails, texts and push notifications
- Bank, credit card and loan records
- Medical, counseling and treatment records
- Employment records showing time off or job loss
- Any self-exclusion or deposit-limit requests
Filing Deadlines
Filing deadlines come from state law. They vary with where a person lives and when the loss, injury or diagnosis happened.
Some states start the clock at diagnosis. A bettor with strong facts can still lose a claim if the window to sue closes first. Talking to a lawyer promptly is wise.
