Sports Betting Addiction Lawsuit: DraftKings and FanDuel Claims Explained

Legal online sports betting spread quickly after the Supreme Court struck down the federal sports betting ban in 2018. The lawsuits argue that DraftKings and FanDuel built their apps and marketing to maximize betting by the customers most likely to lose, rather than to spot and slow down problem gambling.

VIP hosts and targeted promotions

Plaintiffs say sportsbooks assign hosts to high-volume bettors, offer bonuses and gifts, and use customer data to decide when a bettor is most likely to deposit again, including after big losses. In one Philadelphia case, a plaintiff says his VIP host sent him a $500 bottle of champagne.

Microbets and app design

A lawsuit filed March 24, 2026 by the Public Health Advocacy Institute for two Pennsylvania men, Christopher Sage and Terry Thompson, claims that in-game microbets, such as betting on the next play, work like slot machines. It names DraftKings, FanDuel, and Genius Sports, which supplies real-time sports data, and the institute's announcement also named the National Football League.

Misleading bonus offers

Other cases say risk-free, no-sweat, and 100 percent deposit match offers were advertised in ways that hid restrictive terms.

Government actions

The City of Baltimore sued both companies on April 3, 2025, saying they exploited vulnerable gamblers in violation of the city's Consumer Protection Ordinance. In September 2026, the Massachusetts Gaming Commission said it would examine how DraftKings and other sportsbooks use artificial intelligence in promotions, after a New York Times report that DraftKings used machine learning to find customers likely to keep gambling and losing.

The early rulings are mixed and mostly procedural.

• Federal products case dismissed: in March 2026, a federal district court in Pennsylvania dismissed a products liability action that a group of gamblers brought against DraftKings and its subsidiaries. Courts have long been reluctant to impose a legal duty on gambling companies to protect compulsive gamblers from themselves.
• Philadelphia microbet case: filed March 24, 2026 and pending.
• Baltimore: the city's case is pending.
• Massachusetts: the Gaming Commission's AI review, announced September 2026, is an information-gathering step, not a finding of wrongdoing.

In July 2025, DraftKings agreed to return more than $3 million to about 7,000 Connecticut consumers who used deposit match or deposit bonus offers between October 19, 2021 and January 4, 2023, after an investigation by the state's Department of Consumer Protection. That is the clearest money recovered for bettors so far, and it concerned promotion terms, not addiction.

There is no MDL, and there is no class action settlement over sports betting addiction as of September 2026.

These claims are hard, so attorneys look for strong facts:

• Large losses: losses that are significant relative to income, often tens of thousands of dollars or more, including money from savings, retirement accounts, or loans.
• Signs the sportsbook knew: rapidly increasing deposits, chasing losses, betting at all hours, failed withdrawals reversed into new bets, or messages to customer service about a problem.
• Continued marketing: VIP host contact, bonuses, or gifts after those signs appeared.
• Ignored limits: self-exclusion, cool-off, or deposit limit requests that were not honored, or limits that were easy to raise.
• Diagnosis or treatment: records of gambling disorder treatment strengthen a claim.

You probably do not have a claim if you bet recreationally and lost amounts you could afford, or if your only issue is a single bet you think was settled wrong. That kind of dispute usually goes to the sportsbook and your state gaming regulator. For promotion problems, compare our pages on sweepstakes casino lawsuits and video game addiction.

Family members sometimes ask whether they can sue for losses a spouse or parent caused. Generally the account holder is the one with a claim, but family members may have their own claims in some states, for example if marital funds were used, and they can report problems to regulators on the gambler's behalf.

No sportsbook addiction case has produced a verdict or public settlement, so any dollar figure you see online is speculation. If a claim succeeded, damages might include lost deposits, treatment costs, and harm such as emotional distress, depending on the legal theory and state.

Government cases usually produce penalties and practice changes, with restitution only for specific groups, as in Connecticut. Private cases could produce more for individuals with strong evidence, but only if courts accept that sportsbooks owe a duty to problem gamblers, which the March 2026 federal ruling in Pennsylvania did not.

Keep in mind that tax rules treat gambling winnings and losses separately, so talk to a tax professional before assuming any recovery offsets past losses.

• Product liability: the app is a defectively designed product that fosters compulsive betting. The Pennsylvania federal dismissal shows courts may not treat a betting app and its promotions as a product.
• Negligence: the sportsbook failed to use reasonable care toward customers it knew were at risk. The central question is whether any duty exists.
• Consumer protection laws: state and local laws against deceptive and unfair practices, used in the Baltimore case and in promotion claims. Pennsylvania's consumer protection law allows private plaintiffs to recover actual damages or $100, whichever is greater, and courts may triple damages.
• State gaming regulations: many states require responsible gaming tools, self-exclusion programs, and advertising limits. Violations can lead to regulator fines and may support civil claims.

Sportsbook terms of use often include arbitration clauses and class action waivers, which can push individual claims out of court. Read your account's terms before filing anything.

Courts in several states have long refused to hold casinos liable for losses of compulsive gamblers, reasoning that gambling is a voluntary activity and that state gaming laws, not private lawsuits, set the rules for problem gambling. The new cases try to distinguish online sportsbooks by pointing to their data: an app that tracks every bet, deposit, and login knows far more about a customer's behavior than a casino floor ever did, and plaintiffs argue that knowledge creates a duty to act. The March 2026 federal ruling in Pennsylvania did not accept that argument, but other courts, and other states' laws, may come out differently.

Each state's statute of limitations applies, and the clock often starts when the losses occurred or when you discovered the wrongdoing.

• Negligence and product claims: commonly 2 to 3 years.
• Consumer protection claims: commonly 2 to 6 years; Pennsylvania's is generally 6 years.
• Regulator complaints: file promptly, since gaming regulators may only review recent conduct.

Older losses may be partly outside the time limit even if later losses are not, so do not wait if you are considering a claim.

If you self-excluded, note the date, because conduct after that date may be the strongest part of a claim.

Every state that allows online sports betting requires sportsbooks to offer responsible gaming tools. Whether a sportsbook honored those tools is often the strongest part of an addiction claim, because it is easier to prove than a general design defect.

Tools sportsbooks must offer

• Deposit limits: daily, weekly, or monthly caps on how much you can deposit.
• Wager and time limits: caps on bet size or session length in many states.
• Cool-off periods: short breaks from betting, often from 24 hours to several weeks.
• Self-exclusion: a longer ban, through the app or a state program, that is supposed to stop the sportsbook from taking your bets or marketing to you.

Many states make it easy to lower a limit instantly but require a waiting period before a limit can be raised. If a sportsbook let you raise limits immediately, kept sending promotions after you self-excluded, or let you open a new account while excluded, write down the dates and keep the messages. Connecticut's July 2025 action shows regulators will require refunds: DraftKings agreed to return more than $3 million to about 7,000 customers over bonus terms.

VIP programs

VIP hosts are at the center of several lawsuits. Plaintiffs say hosts reached out after big losses, offered bonus credits or gifts, and encouraged new deposits. If you had a host, save every text, email, and direct message, and note any gifts, event tickets, or travel you received. Also note what you told the host about your finances or gambling, since that goes to what the company knew.

Promotions and fine print

Risk-free and no-sweat bets usually refund losses as site credit that must be wagered again, not as cash. Deposit match offers often require wagering the bonus many times before withdrawal. If the ad and the terms did not match, screenshot both. These promotion claims are generally easier to prove than addiction claims, and state regulators handle them directly.

Where to complain

Your state's gaming commission or lottery agency licenses sportsbooks and takes complaints. Regulators can investigate and fine sportsbooks that break state rules, and a regulator finding can also support a private claim.

1. Get support. Call or text 1-800-GAMBLER for confidential help. Most states also run free treatment programs.
2. Self-exclude. Use the app's self-exclusion tool and your state's self-exclusion list, and keep confirmation emails.
3. Download your account history from every sportsbook before closing accounts.
4. Save marketing. Keep VIP host messages, promotional emails, and records of gifts or credits.
5. Report to your regulator. File a complaint with your state gaming commission if limits or self-exclusion were not honored.
6. Do not sign releases. A sportsbook may offer credits in exchange for a release of claims.
