Massachusetts Gaming Commission Settles PHAI Data Lawsuit

The Massachusetts Gaming Commission has agreed to dismiss a lawsuit brought by the Public Health Advocacy Institute after finally collecting and sharing anonymized casino player data with researchers, something Massachusetts law has required since 2011. PHAI and the Commission jointly asked the court to dismiss the case on July 23, 2026, closing a dispute that PHAI filed in July 2024 after 15 years of the requirement going unmet.

Updated July 2026. The resolution means independent researchers can now request anonymized data covering player demographics, loyalty program activity, session times, wager amounts, win and loss figures, jackpot activity, and game characteristics from the state's three commercial casinos, giving public health researchers a data set that has effectively not existed since Massachusetts legalized casino gambling.

What did the Massachusetts Gaming Commission agree to in the PHAI lawsuit?

The Massachusetts Gaming Commission agreed to build and operate a data collection and sharing system that gives outside researchers access to anonymized casino player data, satisfying the statutory requirement PHAI's lawsuit sought to enforce. In exchange, PHAI agreed to the case's dismissal on July 23, 2026, ending litigation that had run since mid 2024.

Key facts

• 2011: the year Section 97 of the Expanded Gaming Act first required the Commission to collect and share anonymized player data, according to PHAI and Gambling Insider's reporting on the case.
• July 2024 to July 2026: the roughly two year span the PHAI lawsuit was active before the Commission's compliance led to its dismissal.
• Three: the number of commercial casinos operating in Massachusetts whose player data is covered, all fully operational since 2019.

Why did PHAI sue the Massachusetts Gaming Commission?

PHAI sued because the Commission had never implemented the data collection system that state law required when Massachusetts legalized casino gambling in 2011. The organization argued that without this data, researchers, regulators, and the public had no independent way to measure how casino gambling was affecting problem gambling rates in the state, more than a decade after the law took effect.

What does the 2011 Expanded Gaming Act require on player data?

Section 97 of the 2011 Expanded Gaming Act requires the Commission to collect data on casino patrons and make an anonymized version available to researchers studying the effects of gambling. The requirement predates any of Massachusetts's three casinos opening, the first of which launched in 2015, meaning the data gap PHAI's suit targeted spanned the entire history of legal casino gambling in the state.

What did PHAI say about the resolution?

"After PHAI filed suit against the Commission in July 2024, the Commission finally took the steps needed to collect player data." - Andrew Rainer, Litigation Director, Public Health Advocacy Institute

"Mission accomplished. We are pleased to join with the Commission today in asking the Court to dismiss the case." - Jacob Wolk, Attorney, Public Health Advocacy Institute

Both quotes, reported by Gambling Insider, frame the outcome as a straightforward compliance win for PHAI rather than a contested court ruling, since the Commission moved to build the system the lawsuit demanded rather than litigate the underlying obligation.

What data will researchers actually get access to?

Researchers granted access will receive anonymized data covering player demographics, loyalty program information, session times, wager amounts, average bets placed, win and loss outcomes, jackpot activity, and game characteristics. That is a materially broader data set than the aggregate revenue and visitation figures the Commission has historically published, since it captures behavioral patterns at the player level rather than casino-wide totals.

Who is handling the anonymization, and how do researchers apply?

The University of Massachusetts was contracted in 2025 to anonymize and manage the casino player data before it reaches outside researchers, and an application portal for researchers opened in July 2026. Routing the work through a university partner gives the Commission an independent layer between raw casino data and the researchers who ultimately study it.

Before and after: what changed at the Massachusetts Gaming Commission

Category	Before July 2026	After July 2026
Statutory compliance	Section 97 requirement unmet since 2011	Requirement fulfilled; case dismissed July 23, 2026
Data available to researchers	None at the player level from casino floor systems	Anonymized demographics, session times, wager amounts, win and loss, jackpot activity, game data
Legal status	PHAI lawsuit active since July 2024	Case dismissed by joint request
Data partner	None	University of Massachusetts, contracted 2025

What other lawsuits has PHAI filed against gambling operators?

PHAI has been an active litigant well beyond Massachusetts. The organization has separately sued DraftKings and pursued cases against Caesars Online Casino and Harrah's Philadelphia over promotional and "pay through bonus" practices it argues are harmful to problem gamblers, part of a broader legal strategy targeting both regulators and operators over consumer protection gaps.

Does this affect Massachusetts sports betting operators too?

Not directly. The resolved lawsuit and the new data sharing system apply specifically to the state's three commercial casinos, not to online or retail sports betting operators. PHAI executive director Mark Gottlieb has said the organization wants to see similar data collection and sharing requirements extended to sports betting operators, signaling this may not be the group's last action on the issue in Massachusetts.

How does this fit into the Massachusetts Gaming Commission's broader research work?

The Commission has run a research agenda since 2013, including the long running Massachusetts Gambling Impact Cohort study and a public research repository, but that work has relied on surveys and aggregate reporting rather than granular, player-level casino data. Bringing genuine player-level data into that pipeline for the first time gives existing MGC-funded research a data source it has lacked since the program began.

What happens next?

Researchers can now apply for access to the anonymized data set through the portal the Commission opened in July 2026, and the first studies drawing on it are expected to take shape over the coming research cycle. The bigger open question is whether Massachusetts lawmakers or regulators extend a similar mandate to sports betting operators, the gap PHAI has already flagged publicly as its next target.
