Massachusetts’ first commercial casino reported more than half of its revenue coming from ‘recaptured’ customers who otherwise would have gambled out of state, according to a new report.

This week, the University of Massachusetts’ Donahue Institute released an economic impact study of Plainridge Park Casino’s first year of operations. The Penn National Gaming casino (slots hall, really) opened its doors in June 2015, the first of three commercial brick-and-mortar casinos authorized by the state legislature in 2011.

The study, which was conducted at the request of the Massachusetts Gaming Commission (MGC), found that customers spent a total $172.5m on both gambling and non-gambling activity at Plainridge Park in the 12 months ending June 30, 2016. Casino visitors doled out a further $3.2m in non-casino spending in the Plainville area over that same period.

Of that $172.5m in casino spending, around $100m came from what the survey called ‘recaptured’ patrons, i.e. gamblers who previously traveled to other states where casinos were legal. Out-of-state residents spent $36m at Plainridge Park while Massachusetts residents spent $36.6m that would otherwise have been spent on other goods or services.
