Online Casino Statistics 2026

US online casino gross gaming revenue reached a record $10.73 billion in 2025, a 27.6% increase and the fastest growth of any commercial gaming vertical except sports betting, according to the American Gaming Association's Commercial Gaming Revenue Tracker. In Europe, the 2025 figures are equally striking: EGBA member operators alone generated EUR 18 billion in online GGR from EUR 275.3 billion in stakes at a 93.4% return-to-player rate, across 43.8 million active accounts. This page compiles the online casino statistics journalists and analysts request most often: US iCasino revenue and launch year for each of the seven legal states, European and UK market data, global market-size estimates with their disagreements shown rather than hidden, game mix, RTP and operator margin, mobile share, and average player metrics. It is reviewed quarterly.

US iCasino: $10.73 Billion in 2025, Up 27.6%

US online casino gross gaming revenue hit $10.73 billion in 2025, a 27.6% year-on-year increase, making it the second-fastest-growing commercial gaming vertical behind sports betting, per the American Gaming Association. December 2025 was the first month in which US iCasino GGR exceeded $1 billion. The vertical crossed a symbolic threshold the same year: annual online casino revenue overtook commercial land-based casino revenue in both Pennsylvania and New Jersey for the first time. Total US commercial gaming revenue across all verticals reached $78.7 billion in 2025, up roughly 9%, with direct gaming taxes of $17.86 billion.

The growth rate is the number worth understanding rather than the absolute figure. US iCasino operates in seven states covering roughly 15% of the US population, so a $10.73 billion result reflects deep penetration in a small footprint rather than broad national adoption. Every credible projection of a $25 billion-plus US iCasino market assumes new state legalizations, not organic growth in the existing seven, and no new state has launched since Rhode Island in March 2024.

US iCasino by State: 7 Legal Markets, Ranked

Pennsylvania led all US online casino markets in 2025 with $3.46 billion in revenue, ahead of Michigan at $3.1 billion in gross receipts and New Jersey at $2.91 billion in internet gaming win. Those three states account for nearly 90% of the national total. The table below compiles full-year 2025 revenue from each state's gaming regulator alongside launch dates and headline tax rates. Readers should note that states use different reporting conventions: Michigan publishes both gross receipts and adjusted gross receipts, and New Jersey's internet gaming win includes online poker.

The two totals in that table do not match exactly, and honest sourcing requires showing both rather than picking one. Summing the seven state-reported figures produces $10.65 billion to $10.85 billion depending on whether Michigan's gross receipts or adjusted gross receipts line is used, against the AGA's national total of $10.73 billion. The gap reflects differing treatment of promotional credits, online poker, and reporting periods across regulators. Cite the AGA figure for a national number and the state regulator figure for a state number, and do not attempt to reconcile them to the dollar.

• Pennsylvania levies the highest headline online slots tax in the US at 54% of revenue, yet remains the largest market by revenue, which is the strongest available counter-argument to the claim that high tax rates suppress iCasino market development
• Delaware and Rhode Island run state-lottery monopoly models with a single operator rather than open competitive markets, which is why their absolute revenues stay small despite mature launch dates
• New Jersey and Delaware both launched in November 2013 and are the two oldest US iCasino markets, giving them more than a decade of continuous monthly data
• Rhode Island, launched March 2024, is the newest market and the only US iCasino launch since 2021
• Delaware, Rhode Island and West Virginia posted the strongest percentage growth in 2025, a base-effect result off small absolute revenue rather than evidence of faster underlying adoption

Europe: Online Is 40% of a EUR 127.7 Billion Market

Europe's total gambling market reached EUR 123.4 billion in gross gaming revenue in 2024, a 5% increase, and was projected to reach EUR 127.7 billion in 2025, according to the European Gaming and Betting Association's Key Figures report produced with H2 Gambling Capital. Online gambling accounted for 39% of that total in 2024, up from 37% in 2023, and was projected to cross 40% during 2025 at roughly EUR 51.1 billion. Europe is therefore both the largest regulated online gambling region in the world and the one with the most reliable published data, because the EGBA and H2 series is compiled from operator and regulator reporting rather than modelled from consumer surveys.

Values marked implied in that table are Track360 back-calculations from published growth rates rather than figures EGBA published directly, and they are flagged so that no reader attributes a derived number to EGBA. EGBA members represent approximately 30% of European online gross gaming revenue, so member data is a large, consistent, but not exhaustive sample of the regulated European market. National regulators including the UK Gambling Commission, Germany's GGL, and Italy's ADM publish their own market data on different reporting calendars, which is why cross-market European comparisons rarely align on a single reference year.

Great Britain: GBP 5.0 Billion Online Casino GGY, GBP 4.2 Billion From Slots

Online casino games generated GBP 5.0 billion in gross gambling yield in Great Britain in the financial year April 2024 to March 2025, of which GBP 4.2 billion came from slots alone, a 16.7% increase on the previous year, according to UK Gambling Commission industry statistics. The wider remote casino, betting and bingo sector produced GBP 7.8 billion, with remote betting contributing GBP 2.6 billion (football GBP 1.3 billion, horse racing GBP 766.7 million) and remote bingo GBP 165.6 million. Great Britain is the single most granular online gambling dataset in the world because the UKGC compels quarterly product-level reporting from every licensee.

Slots represent 54% of all British remote gambling yield and 84% of online casino yield, which makes Great Britain a slots-dominant market to a degree that few others match. The 4.1% fall in new account registrations alongside 16.7% slots growth is the tension underlying UK policy debate: revenue is rising on a flat or shrinking player base, which means average spend per active account is increasing. That single relationship drives most UKGC intervention, including deposit limits, affordability checks, and the stake limits applied to online slots.

Global Market Size: Estimates Range From $88 Billion to $100 Billion

Credible research firms placed the 2025 global online gambling market anywhere between $88.0 billion and $99.7 billion, a spread of more than 13%, and any single-figure claim about global online casino market size should be treated as one estimate among several. Grand View Research valued the online gambling market at $88.0 billion in 2025. IMARC Group valued it at $99.7 billion for the same year. Both are defensible; they simply define the market differently, with variation in whether sports betting, poker, lottery, and grey-market activity are included and whether revenue is measured as GGR or consumer spend.

The practical guidance for anyone citing a global figure is to prefer regulator-sourced regional totals over modelled global ones. The AGA, UKGC, and EGBA numbers in that table are compiled from compelled or member reporting and can be audited back to a filing. The two global market-size figures are models built on assumptions their publishers do not fully disclose. Where a story needs a global number, cite both estimates and name both firms, exactly as this page does.

Game Mix: Casino Games Are 48% of EGBA Member GGR

Casino games accounted for 48% of EGBA member gross gaming revenue in 2025, ahead of sports betting at 46%, poker at 3%, and other products at 3%, per EGBA member data. That casino-first split is the reverse of the US commercial picture, where sports betting revenue of $16.96 billion is well ahead of iCasino's $10.73 billion, and it reflects Europe's two-decade head start in regulated online casino. Within the casino category, slots are the dominant product wherever regulators publish product-level data, reaching 84% of online casino yield in Great Britain.

Live dealer and RNG table games make up the remainder of casino revenue, but very few regulators publish a clean live-versus-RNG split, so widely circulated percentages for live dealer share are vendor estimates rather than official statistics. Track360 does not publish a live dealer share figure for that reason. Where a live dealer number is needed, the UKGC's aggregate online casino category and its separately reported slots line give the most defensible bound: slots are GBP 4.2 billion of a GBP 5.0 billion category, leaving roughly GBP 0.8 billion for all non-slot casino products combined in Great Britain.

RTP and Margin: 93.4% Returned to Players in 2025

The average return-to-player rate across EGBA member operators was 93.4% in 2025, down from 93.7% in 2024 and falling in every year since 2021, while operator margin rose to 6.6% from 6.3%. Those two figures are the same coin: EUR 275.3 billion staked producing EUR 18 billion in GGR implies a 6.5% hold, and every basis point of RTP reduction converts directly into operator revenue. EGBA attributes the decline to operators offsetting rising gambling taxes and the revenue impact of deposit and stake limits, which is a rare instance of an industry body publishing a margin-expansion mechanism explicitly.

The 34% GGR growth against 28% stakes growth in that table is the single most useful ratio in European online gambling right now, because it isolates how much of the industry's revenue growth came from margin rather than volume. Roughly a fifth of the revenue increase is attributable to the RTP reduction rather than to more betting. Journalists writing about operator performance should be aware that a headline revenue increase in this market can coexist with flat or slower-growing player activity, and the stakes line is the better proxy for consumer behaviour.

Mobile and Player Metrics: 58% Mobile, 43.8 Million Active Accounts

Mobile devices generated 58% of European online gambling gross gaming revenue in 2024, up from 56% in 2023, and the EGBA and H2 Gambling Capital series projects that share reaching approximately 67% by 2029. Active account numbers grew alongside: EGBA members reported 43.8 million active customer accounts in 2025, a 13% increase, while Great Britain recorded 24.4 million active remote accounts at the end of the reporting period against 34.0 million new registrations for the year, itself down 4.1%.

The per-account averages in that table are Track360 calculations produced by dividing published revenue and stakes totals by published active-account counts, and they should be read as arithmetic rather than as behavioural findings. Active-account definitions differ between EGBA members and UKGC licensees, accounts are not people, and a single player commonly holds accounts at several operators. Any per-player spending claim built on these numbers overstates individual spend, which is why this page publishes them as per-account rather than per-player figures.

What These Numbers Mean for Operators and Casino Affiliate Programs

Three structural features of this data determine how a casino affiliate program has to be built: a slots-dominant product mix, a compressing RTP that changes NGR economics, and a fragmented licensing map that makes geo-targeting a compliance requirement rather than an optimisation. Because RevShare deals are calculated on NGR rather than GGR, the deductions between the two, bonus costs, gaming duty, payment fees, and jackpot contributions, determine what a partner actually earns, and a falling RTP raises GGR faster than it raises the NGR that partners are paid on. Operators holding MGA and UKGC licences alongside national permits from Germany's GGL and Italy's ADM face different permitted-marketing rules per market, so partner traffic has to be geo-targeted at the tracking layer and qualification rules set per jurisdiction rather than globally. Fraud controls follow the same product logic: slots-led acquisition attracts bonus abuse, multi-account signups, and self-referral schemes at rates that sports-led programs do not see, which is why casino programs need device and payment-level duplicate detection rather than cookie-based checks alone. Commission design responds to the same pressures, with hybrid deals combining a reduced CPA and ongoing RevShare now standard, negative carryover terms contested market by market, and player lifetime value modelling driven by slots session frequency rather than deposit size. Disclosure obligations sit on top of all of it, from UKGC licence conditions and MGA licensee obligations in Europe to FTC endorsement guidance for US-facing content, so affiliate compliance review has to be continuous rather than an onboarding checkbox.

Methodology and Sources

Three source classes cover this page: national gaming regulators, the EGBA and H2 Gambling Capital data series, and named market-research firms for global estimates, with every Track360 calculation labelled inline. This page follows a fixed process.

1. US national iCasino totals are taken from the American Gaming Association's Commercial Gaming Revenue Tracker and State of the States reporting for full-year 2025.
2. US state figures are taken from each state's gaming regulator (Pennsylvania Gaming Control Board, Michigan Gaming Control Board, New Jersey Division of Gaming Enforcement, Connecticut Department of Consumer Protection, West Virginia Lottery, Delaware Lottery, Rhode Island Lottery), using each regulator's own published metric name; where a state publishes more than one revenue measure, both are shown.
3. European market totals and mobile share come from the EGBA and H2 Gambling Capital Key Figures 2025 Edition; EGBA member performance, RTP, margin, stakes and active accounts come from EGBA member reporting published in 2026. EGBA members represent approximately 30% of European online GGR and are a sample, not the whole market.
4. Great Britain figures are taken from UK Gambling Commission industry statistics for the financial year April 2024 to March 2025.
5. Global market-size figures are attributed individually to Grand View Research and IMARC Group. Where those estimates conflict, both are shown with the publisher named; neither is presented as the market size.
6. Track360 calculations are limited to arithmetic on published figures: subtraction to derive non-slot casino yield, division to derive per-account averages, and back-calculation of prior-year values from published growth rates. Each is labelled at the point of use and none is attributed to a third party.
7. This page is reviewed quarterly and after any AGA, EGBA, or UKGC publication that changes a headline figure; the next scheduled review follows the Q3 2026 reporting cycle.
