US Online Casino Revenue Hits $1.02 Billion in September 2026

Data compiled by Sports Betting Dime shows that US online casino revenue reached $1.02 billion in September 2026, which marks a 12.9% increase compared with the same month in the previous year, and the figures cover activity across seven states where iGaming operates legally.

Pennsylvania, Michigan, and New Jersey together accounted for the largest share of that total, while every state in the group recorded growth rather than any declines, and the rates varied from 6.5% in Connecticut up to 29.3% in Delaware.

State-Level Breakdown of Revenue

Observers note that the three leading states generated the bulk of the $1.02 billion figure, which reflects their established player bases and mature regulatory frameworks that have supported consistent activity since legalization, whereas smaller markets such as Connecticut and Delaware contributed smaller absolute amounts but still posted measurable gains.

Connecticut recorded the slowest growth rate among the group at 6.5%, yet its revenue still rose year-over-year, and Delaware posted the strongest percentage increase at 29.3%, which lifted its contribution despite the smaller overall market size, while the remaining states fell somewhere between those two extremes and together helped drive the national total higher.

Year-Over-Year Growth Patterns

Figures reveal that the 12.9% increase occurred across all seven states without any reported declines, and this pattern continues a multi-year trend of expansion even as some observers point to signs of cooling in certain markets where growth rates have moderated compared with earlier periods of rapid adoption.

Research indicates that states with longer operating histories, such as New Jersey and Pennsylvania, maintained substantial revenue volumes, while newer entrants benefited from regulatory stability and increased player awareness that supported the overall upward movement through September 2026.

Those who track monthly reports note that the absence of any state showing a drop provides a clear signal of sector resilience, and the spread of growth rates highlights how local factors such as marketing spend, game variety, and tax structures influence outcomes differently across jurisdictions.

Context Entering October 2026

As October 2026 begins, the September numbers offer a snapshot of continued expansion in the iGaming sector, and regulators along with operators can review the data to assess performance against earlier projections while planning for the final quarter of the year.

Evidence suggests that the sector remains on an upward trajectory overall, even though some markets show slower percentage gains than in prior years, and the combined $1.02 billion total underscores the scale that has developed since the first states legalized online casino play.

Implications for the Broader Market

Analysts who follow these reports point out that Pennsylvania, Michigan, and New Jersey continue to dominate because of their large populations and established player pools, yet the gains recorded in smaller states demonstrate that expansion opportunities still exist when regulatory conditions allow new operators to enter or existing ones to scale.

The data also shows that every state in the tracked group posted positive movement, which contrasts with occasional volatility seen in other gambling verticals and reinforces the steady demand for online casino products across the legal landscape.

Conclusion

The September 2026 revenue total of $1.02 billion, compiled from gross gaming revenue reports across seven states, reflects a 12.9% year-over-year rise driven primarily by Pennsylvania, Michigan, and New Jersey, with additional contributions from Connecticut, Delaware, and the remaining markets that together produced growth rates ranging from 6.5% to 29.3% and no reported declines. The full compilation provides further detail on state-by-state performance and places the figures in the context of ongoing sector development as operators and regulators move into the final months of 2026.
