The revenues of online casinos are the story no one is telling. Sports betting gets all the credit with its legislative drama, partnerships, and celebrities advertising in primetime. iGaming just … exists. It is legal in fewer states, not everyone knows it’s there, and legalization is forever running into political speed bumps. It’s moving far more slowly than anyone expected when the online gaming expansion started. But here’s the thing: Incentive states with functioning online casino markets reach revenue per player that is much greater than what sports betting generates and can even dream about. The monthly figures from regulated iGaming states in 2026 tell a story that can no longer be ignored – the online casino market is thriving.

Reading the Data – GGR, NGR, and What the Numbers Mean

When casinos report revenues, there are so many terms, which are so freely bandied about, that the same headline might mean completely different things depending on where you’re reading it. Let’s try to explain some of them before going any further.

Gross Gaming Revenue (GGR)

GGR is always the baseline for any revenue. It is the total wagers minus what actually gets paid out to winning players. In other words, the operator’s gross win is before they pay anything else. Dead simple in the case of slots, but table games and live dealer games get a little trickier. Every state has its own eccentricities in how they want it calculated. When regulators are citing revenue or working out taxes, this is the number they use.

Net Gaming Revenue (NGR)

NGR is what’s left from GGR when promotional costs, bonus credits, free play, and deposit matches are paid for. Here is the catch: some states tax GGR, others tax NGR. A state that taxes NGR, in practice, gives operators a way to deduct their promotional spending before taxes hit. In the larger market, that can mean tens of millions of dollars difference in what actually gets collected.

Slots	Video slots, jackpot titles, new variants	Typically makes up 70 to 80% of total GGR
Table Games	Blackjack, roulette, baccarat, variants	Live dealer driving share increase
Poker	Cash games, tournaments	Rarely exceeds 10% of GGR
Live Dealer	Real-time streamed table games	Fastest growing segment, increasingly reported separately

National Revenue Overview – 2026 Year to Date

The national online casino GGR for the first quarter of 2026 shows healthy growth with no sign of volatility, as it was in the early years. Unlike sports betting that swings wildly according to the calendar, online casino revenue follows a steady pattern. There’s no offseason for slots. The regular player bases its play on habits rather than on events of fate over which it has no control, generating a revenue curve that is more predictable than its sportsbook cousin’s.

The first three months of 2026 have tracked above prior year figures across every regulated state-organic growth within established markets rather than new state additions driving the bulk of the increase.

January 2026

January is always the best month of every first quarter, thanks to post-holiday engagement that inevitably increases casino activity. 2026 was no different. The overlap with NFL playoffs drove more traffic to platforms offering both sportsbook and casino bets. Sports fans came in for sports wagers, but made some casino bets as well. Slot volume was particularly strong, and live dealer table game revenue reached its highest January in several states. National GGR was up from the same period in 2025. What does it mean? The player base is not only growing, but it also spends more per session.

February 2026

February reached better numbers than comparable sports betting figures, which took a big fall in the wake of the Super Bowl. It showed the big difference between sports betting and online casino play. Casino players don’t need to wait for a game to log in and bet. Their games are always there and don’t depend on the sports calendar and major events.  Monthly GGR was down a little bit from January, which is to be expected.

March 2026

March got some of the lost ground in February. Sports fans returned for the NCAA Tournaments, and casinos benefited from sportsbooks’ traffic. The effect was obvious in the spike of casino game sessions. This is an annual thing that online casinos consider and plan for. Slot GGR moved back toward January levels in many states, and poker revenue, typically the most stable of all games, moved higher, too.

Month	Trend	Factor
January 2026	Above prior year – strongest month of quarter	Post-holiday engagement, NFL playoff overlap
February 2026	Modest dip from January – held better than sports betting	Super Bowl traffic without post-event drop-off
March 2026	Recovery toward January levels	NCAA Tournament platform spillover

What Q1 shows is that iGaming states are producing consistent, rising revenue without the fluctuations by sports bets and the “special event” gaming they trigger. Rapid and reliable growth is a good argument for expansion, and it is being made by advocates in unlicensed states.

The Established Markets

There are seven states with regulated online casino markets in the US right now. They are united by the legal casino gaming, but divided by different tax structures and market sizes.

1. New Jersey is the leader that sets the tone. This state produces the highest month-to-month revenues each time, mainly due to having a large population and years of experience.
2. Pennsylvania has a weird tax model with slots at 54% GGR and tables not much better at 16%. This meant the operators had to adjust their state operations, and despite all that, the market produces some decent monthly numbers.
3. Michigan is the inspiration for those still dithering on the cusp of iGaming regulation. By going live with a casino launch alongside sportsbooks, Michigan stole a march on the old guys with its inherent cross-sell advantage. Casino GGR often exceeds sportsbook GGR, which is curious when you think about how much flashier sportsbook marketing is across the US.
4. Connecticut utilizes a compressed two-operator model catering to tribal gaming, which is a difficult task, yet continues to generate impressive revenue.
5. Delaware has the most established precedent of online casino gaming, though it is limited by its population base.
6. West Virginia, having launched in 2020, has also continued to grow, and is the headquarters for people from surrounding states who drive there to play casino games.
7. Rhode Island is the new kid on the block, and its early numbers are very impressive, given it has a small population.

State	Tax Rate	Launch
New Jersey	15% GGR	2013
Pennsylvania	54% slots / 16% tables	2019
Michigan	20-28%	2021
Connecticut	18% GGR	2021
Delaware	~43% blended	2012
West Virginia	15% GGR	2020
Rhode Island	20% GGR	2024

The Expansion Picture – States Moving Toward Legalization

Revenue figures from established markets have really changed the tone of iGaming discussions. You look at how much money these states make month-on-month, and it’s harder to be opposed to legalization in 2026 than it was five years ago! Data numbers are public, they’re massive, and they’re positive.

• New York is first on the list of possible new additions. The size of both the population and sports betting per capita indicates that an online casino market would immediately become the biggest in the country. Bills have been introduced, but nothing has progressed, because land-based casinos form a strong opposition. There are also cannibalization concerns about soon-to-be licensed commercial casinos that don’t want to go out of business before even opening. Movement is possible, but not likely in the next few months.
• Illinois has started one of the more mature legislative conversations in regulated states nationwide. It has a large existing casino infrastructure that could serve as a licensing backbone, and revenue projections attached to recent proposals are large enough to keep the conversation going.
• Indiana gives a similar look: they have functioning sports betting, an existing land-based market, and a regulatory infrastructure that could absorb iGaming without any difficulty.
• Georgia is anomalous in this group. There is no legal sports betting there, but iGaming is viewed as part of the overall expansion of gambling as opposed to just another piece of the pie. The discussion, however, has come to a slowdown, and there is stronger pushback than in the Midwestern markets, which means it would be harder to pass.
• Maryland has some proposals, but they are always falling short when it comes to voting. Which is strange considering they are next to New Jersey, making the fiscal case crystal clear.

If all these states rubber-stamp online casinos, then it will obliterate national iGaming totals. One New York launch would probably add thousands of GGR per month.

Slots vs. Table Games vs. Poker – Where Revenue Actually Comes From

Examining the games themselves and looking at how they fit into the system is more telling than headline numbers alone. How a market’s money is made says as much about players and operators as headline revenue says about size.

• Slots have always been the beast in online casinos, generating between 70% and 80% of total GGR across regulated states so far this year, and nothing is going to shift this dominance. What has changed, however, is the mix. Slots with a higher level of volatility and bonus mechanics are growing as a share of revenue. Why? They feature mechanics that accelerate play, drive greater average bet size, and earn more per session than normal slots.
• Table games were gradually developed, but their share of revenue rose exorbitantly at the point of live dealer introductions. Standard RNG table games have remained flat, but when games with real dealers started to emerge, share was eroded from digital tables and even slots. Evolution Gaming’s titles make up the majority of live dealer content across regulated US states.
• Poker stands on its own. Its revenue is stable, and in the end, it keeps its players spending moving: consistent GGR (if not always growing) month to month, which is valuable for any casino.

Vertical	GGR Share	2026 Trend
Slots	70-80%	Stable dominance
Table Games	15-25%	Growing
Poker	5-10%	Stable
Live Dealer	Subset of tables	Fastest growing segment

Tax Structures and Public Revenue – How States Are Collecting

While tax rates on sports betting often steal the headlines, the tax structure for online casino gambling is where much more important decisions are made. The rates are higher, which means higher revenue per player. It all leads to starkly different fiscal outcomes, based on policy approach.

The Rate Landscape

The elephant in the room is Pennsylvania. It is the market where every iGaming tax conversation eventually comes to, because of its 54% tax on slot GGR. Highest in any regulated market. It was deliberately agreed to be that high during legislation, partly to optimize economic generation, partly to stem potential erosion of land-based casinos. The market survived it, since Pennsylvania’s population base is large enough to support operator investment either way. But it shaped the market, pushing operators to invest in table games, where a much lower rate ot 16% applies.

New Jersey’s 15% flat rate is at the other end of the spectrum, and it’s making a very compelling case as to how moderate taxation over time yields a healthier, more competitive market to work with. The amount of money NJ collects at 15% on a stable, high-volume market that they’ve built will almost always gross more than what states with 50%+ tax rates can hope to squeeze out of their operators.

Revenue Allocation

States decide how to distribute the tax money generated by online casinos, but a handful of options are typical:

• General fund contributions – Almost all states shuffle the bulk of their funds from iGaming into general funds with no specific allocation designated.
• Problem gambling programs – Most regulated states mandate a specific proportion of the tax revenue to be funneled towards problem gambling treatment and prevention programs. The amounts vary, but the requirement is almost universal across regulated markets.
• Education funding – Several states allocated some of their casino betting revenues for public education, either as a dedicated fund or in addition to what is appropriated.
• Land-based casino support – Pennsylvania decided to give out a portion of its iGaming revenue toward bolstering the horse racing industry as a sign of respect for the compromises that needed to be made during legalization.

iGaming vs. Sports Betting Tax – The Dual Market Comparison

There are some states where sports betting and iGaming are both legal, and iGaming tax contribution still exceeds sports betting even with lower handle totals. The reason is simple – casino GGR margins are by definition higher than those in sportsbooks, meaning there is more revenue to tax from a single player’s gaming session.

State	iGaming Tax Rate	Sports Betting Tax Rate
New Jersey	15% GGR	13% GGR
Pennsylvania	54% slots / 16% tables	36% GGR
Michigan	20-28%	8.4% GGR
West Virginia	15% GGR	10% GGR

The Final Verdict

Numbers from 2026 online casino revenues in regulated states make the case plain. Seven states built functional iGaming markets, and each generates revenues that are reliable, keep growing, and are larger per player than sports betting. Back in the day, there was the money argument when talks about allowing iGaming were brought up. Before it was a hypothetical case, but now there is data that can prove how much each state can profit.

Revenues also show that structure matters. Pennsylvania, having a large population base, can work with 54% slot tax and survive it. New Jersey, with its 15% slot tax, is still a profitable state because of mature players and a competitive operator field that is compounded over time. States are potentially looking at legalization this year or next. New York is the most prominent, but there are a bunch of other states, and they will make decisions with tax and licensing that will shape their business for a long time. Making the right decisions at that time is more important than getting to market quickly. The seven-state map will grow, that is certain. Revenue case is proved, operational roadmaps exist, and the competitive risk of neighboring states taking all the player spending is a very real problem for  lawmakers. Why would they risk losing local payments, going to other states?

What the data from 2026 can’t tell you is how fast stepping into the iGaming market can happen and which states will get there first. But what it tells you is that states that are already in the market are producing results that need to be noticed, and states that are not yet live are leaving millions of dollars on the table, simply because they are reluctant to change.
