Online casino revenue numbers from US state reports give a surprisingly clear picture of what players are actually spending time and money on. iGaming totals exceeded $1 billion in May 2026, and the breakdown by game type – slots, table games, poker – is where the useful information is.
These figures come from regulated, state-authorized markets. That distinction matters because the data is verified through gaming control boards rather than estimated by third-party analysts. It’s public, auditable, and broken down by game category – none of that is typical for gambling data outside the US.
Why Regulated Online Casinos Are Still Growing
Regulated iGaming refers to online casino play reported through state-authorized operators. In the US, that currently means seven states where online casinos are legal and actively tracked.
Game categories producing revenue in regulated US markets – pokies, live tables, poker – are the same ones players gravitate toward on platforms globally. One look at the Betway Zambia casino login page, for instance, and the lobby organizes itself the same way US operators do: slots filling the front page, with table games and live dealer categories grouped separately.
No new state markets have opened since 2024, so the growth is coming from existing player bases spending more. But that’s precisely what gives the data clarity – it isolates demand from supply-side noise.
National Growth Sets The Market Context
US iGaming generated $1.03 billion in May 2026, a 14.7% increase over the same month the previous year, per the American Gaming Association’s revenue tracker.
Year-to-date through May, iGaming revenue totaled $4.29 billion, up 29.5% compared to the same period in 2025. Pennsylvania, Michigan, and New Jersey account for approximately 90% of the total.
AGA president Bill Miller noted that iGaming continues to be the fastest-growing segment of the US commercial gaming market, but the pace of expansion has slowed over the past few months with no new states entering.
How Different Game Categories Perform
State regulators report online casino revenue across separate categories: slots, table games, and poker.
Slots dominate by a wide margin, thanks to big shifts in their quality over recent years. Improvements in the visual and audio effects used have led slots to be far more immersive and engaging – they’re no longer a one-dimensional product.
Table games provide a smaller but consistent return. Online poker, despite how much media coverage it gets, produces a fraction of the overall total.
Breaking the numbers down by game type is the difference between a headline about “iGaming growth” and understanding that nearly 80% of that growth is driven by one category. Without the split, a $1 billion monthly total could mean anything. With it, the picture is specific.
Slots Dominate The Revenue Split
Pennsylvania’s June 2026 iGaming data provides a clean illustration. Total online casino revenue came in at $242.5 million.
- Online slots accounted for $190.8 million
- $49.3 million came from table games
- Poker brought in $2.4 million
| Game Category | June 2026 Revenue | Share of Total |
| Online Slots | $190.8 million | 78.7% |
| Table Games | $49.3 million | 20.3% |
| Online Poker | $2.4 million | 1.0% |
Slots producing nearly 79% of Pennsylvania’s online casino revenue isn’t an outlier – similar proportions appear across other regulated states. Betway Zambia’s casino lobby prioritizes pokies and slots the same way, with table games and live options organized as secondary sections.
State Markets Continue Expanding
Michigan recorded $301.2 million in iGaming gross receipts for June 2026, with adjusted gross revenue up 28% year-over-year. All 15 authorized operators in the state now offer online casino games.
Pay attention to that operator count.
Michigan’s growth isn’t coming from adding licensees – the existing 15 platforms are converting and retaining players more effectively. Through six months of 2026, Michigan has generated $1.80 billion in iGaming revenue, putting it on pace to finish the year well past the $3.09 billion it recorded in 2025.
And the gap between Michigan and Pennsylvania, the two largest US iGaming markets, has narrowed considerably. Pennsylvania’s adjusted gross revenue figure was only slightly ahead of Michigan’s for June. If Michigan’s year-over-year growth rate holds through the second half of 2026, it could overtake Pennsylvania by early 2027.
Looking At The Numbers Differently
Category-level data gives a better read on online casino demand than combined revenue totals. Slots take the vast majority. Table games hold a steady portion. Poker produces about 1% of total revenue in the largest state market, despite the media attention around it.
Operators outside the US are clearly paying attention. Betway’s Zambian casino platform structures its game lobby in line with the same demand patterns – slots dominate the visible page, with table games and live dealer titles positioned as supporting categories.
