State of Play’s TL;DR
- Connecticut’s online casino and sports betting market is being cited as a warning sign for other legal states.
- Treatment providers, researchers, and recovery groups report more hidden and fast-moving gambling harm.
Connecticut’s experience with legal online casinos and sports betting is emerging as a high-profile case study in how mobile gambling can intensify addiction risk.
State research and treatment data cited by The Day show rising helpline demand, growing self-exclusion, and greater exposure among younger users.
Five years after Connecticut online casinos and sports betting launched, treatment providers and recovery groups say gambling problems are becoming easier to hide and harder to interrupt. The shift matters beyond one state because Connecticut is among the early US jurisdictions with both legal online casinos and online sports betting.
Helpline calls, self-exclusion, and youth gambling are all climbing
According to The Day, roughly 10,900 people are now on Connecticut’s voluntary self-exclusion list, citing data from the Connecticut Department of Consumer Protection. That is up from about 3,000 people two years into the launch of online gaming.
Paul Tarbox of the Connecticut Council on Problem Gambling said helpline calls rose 112% in the first year of online gaming’s expansion and remain 235% above 2020 levels. A 2025 Connecticut School Health Survey also found 25.8% of high school students reported gambling at least once in the prior 12 months, up from 18.4% in 2021.
Treatment providers said the core change is constant access.
Celaura Estrada of the Bettor Choice Gambling Treatment Program described mobile wagering as having “essentially a gambling venue in your pocket,” adding that it can happen “almost anywhere.”
Research suggests a large share of revenue comes from vulnerable players
A Gemini Research study cited in the report estimated that about 52,000 Connecticut adults had a gambling problem as recently as 2023, with another 139,000 considered at risk.
The study found that at-risk and problem gamblers generated 70% of the state’s $1.9 billion in gross gaming revenue in fiscal year 2022.
The same research found sportsbooks derived more than 50% of revenue from problem gamblers, who made up 1.8% of Connecticut adults.
That data gives the story broader industry relevance for legal states weighing how to balance market growth with responsible gambling safeguards.
Why Connecticut’s experience matters for legal online casino states
The report includes accounts from recovery groups and people in treatment who say phone-based betting is less visible than a trip to a casino and can accelerate losses.
One Connecticut woman, identified as Kristen, said she spent 27 hours playing slots after opening a gambling app for the first time. She said she turned $260 into $11,000, withdrew $900, and then lost the rest until only 2 cents remained.
The article also said Kristen was already on Connecticut’s self-exclusion list but still received Foxwoods promotional mailings.
In statements to The Day, the Mohegan Tribe said it has contributed more than $15 million to problem gambling prevention, treatment, and research, while the Mashantucket Pequot Tribal Nation said it remains committed to responsible gaming across physical and digital operations.
For operators, regulators, and players, Connecticut’s market is offering a clearer picture of the tradeoff in legal online gambling: more convenience and participation, but also more friction for prevention, monitoring, and recovery.
