September’s US Online Casino Revenue Breakdown

Here’s a look at how each of the seven states performed in September compared to a year ago. It should be noted that some states individually report their adjusted gross revenue (AGR), which removes promotional spend from their wins. This table reflects the gross gaming revenue, which is the amount produced prior to promo spend being removed.

Online Casinos Add $116 Million

With the 12.9% growth year-over-year, the seven US online casinos added another $116.7 million in revenue in September compared to a year ago.

Each of the states saw at least 6.5% growth, while four states saw 15% improvement or greater.

The year-over-year increase is still slowing down.

While this year was significantly less in added revenue, over the two year stretch, online casino revenue was up $307 million.
