A year after two new casinos opened in Atlantic City, the seaside resort’s gambling and sports betting revenue is up nearly 8%, and its top casino had its best month ever. Figures released Wednesday by the New Jersey Division of Gaming Enforcement show the casinos took in $323 million, an increase of 7.8% from July 2018. That’s when the city’s two newest casinos, Hard Rock and Ocean, were in their first full month of operation. July’s figures were the first true apples-to-apples comparison in a year of how the Atlantic City casino market had been doing.
