Lawsuit against DraftKings over use of AI in promotions

DraftKings was sued in a proposed class action filed on October 3, 2026, in the U.S. District Court in Boston for allegedly using artificial intelligence to identify customers more likely to respond to promotions and keep betting. The plaintiff, Daniel Vest of West Virginia, says he lost thousands of dollars on his DraftKings account over several years and received at least 70 promotional communications — emails, text messages and others — in the course of a single month encouraging him to continue wagering.

What the lawsuit alleges against DraftKings over AI

Vest’s complaint alleges that DraftKings’ systems analysed wagering data to flag customers the company considered more likely to accept incentives and therefore continue spending. Vest seeks to represent other customers who, the complaint alleges, were identified by those machine-learning systems and targeted with similar promotional campaigns.

The complaint brings two main claims: violation of Massachusetts law for failing to disclose to customers the use of AI to target promotions, and an unfair business practice of sending incentives to people who could suffer economic harm. Vest seeks compensation for his losses and asks that the case proceed on behalf of a class of customers with comparable experiences.

DraftKings’ response and the media context

DraftKings has denied the allegations. The company said it does not use artificial intelligence to target promotions to customers based on their losses or indicators of problem gambling. That statement followed an investigation by the New York Times that asserted the opposite: that DraftKings used machine learning to examine betting patterns and identify users who were more likely to keep wagering and lose money after receiving promotions.

The New York Times report acted as a public trigger; Vest’s lawsuit takes those journalistic claims and translates them into concrete legal allegations against the operator.

Regulatory reaction: the Massachusetts Gaming Commission review

The Massachusetts Gaming Commission (MGC) announced it will examine how DraftKings and other licensed sportsbooks use artificial intelligence. Jordan Maynard, chair of the MGC, said on September 24 that the commission would start by engaging in dialogue with DraftKings to clarify the practices cited by the New York Times.

The MGC’s intervention places the controversy inside the state regulatory arena and raises the prospect of inspections or information requests to operators licensed in Massachusetts. The fact the commission will “engage in dialogue” with DraftKings creates an administrative path parallel to the civil litigation.

Procedural details and jurisdiction

The case was filed in the U.S. District Court in Boston and is framed as a proposed class action under Massachusetts law. Daniel Vest is the individual plaintiff seeking to represent other customers in the same situation. Vest alleges cumulative losses over a period of years and documents an episode in which he received at least 70 promotional messages in one month, a central element of his claim about aggressive marketing practices.

No relevant court deadlines have been published in the available complaint yet, nor is there information about whether the court will grant class certification. The success of the complaint will depend on technical evidence about the AI models, DraftKings’ internal data flows, and the relationship between promotional campaigns and customers’ loss patterns.

Implications for operators and AI vendors in betting

The litigation and the MGC review could increase scrutiny of the use of analytics and machine learning tools by sportsbooks. For operators and technology providers, key questions will include:

• how customers are labeled and segmented within predictive models,

• whether safeguards exist to identify signs of problem gambling before sending incentives,

• and what transparency is provided to users about the use of algorithms in commercial communications.

For licensees in regulated markets such as Massachusetts, failing to disclose use of AI in marketing could become a regulatory and civil liability vector.

“The commission will first meet with DraftKings to clarify the practices cited by the New York Times,” Jordan Maynard said on September 24.

DraftKings, for its part, maintains that its practices do not match the media description and that it does not target promotions based on losses. The litigation will force both sides to document internal processes and potentially subject algorithmic models to external review.

What to watch next

The items to monitor in coming weeks are: whether the court grants class certification, the document exchanges between the parties that could reveal the architecture of the AI models, and the outcomes of the review initiated by the Massachusetts Gaming Commission. The case could set precedents on the intersection of machine learning, marketing and consumer protection in the betting sector.
