Atlantic City's casinos were less profitable in 2023 than they were a year earlier, even with help from the state's booming online gambling market. Figures released Monday by the New Jersey Division of Gaming Enforcement show the nine casinos collectively reported a gross operating profit of $744.7 million in 2023, a decline of 1.6% from 2022. When two internet-only entities affiliated with several of the casinos are included, the decline in profitability was 4.1% on earnings of $780 million.
