How Big Is Online Gambling? Market Size and Statistics 2026

TL;DR

There is no single number, and anyone who gives you one without telling you what it counts is selling something. H2 Gambling Capital puts global online gambling at $293bn in gross gaming revenue for 2024; Grand View Research puts the "online gambling market" at $97.7bn for 2026, on a metric it never states. The UK regulator, reporting actual operator returns, recorded £7.8bn of remote gross gambling yield for April 2024 to March 2025, which is 46.4% of the GB industry including lotteries and 61.9% excluding them. A 2024 Lancet Public Health meta-analysis found 7.8% of adults gambled online in the past 12 months, with a confidence interval of 6.2% to 9.5%, and published no headcount at all. Crypto gambling estimates span $5.7bn to $81.4bn a year. What we can count ourselves: 1,493 Anjouan licences across 4,008 domains on 17 August 2026, of which 286 are past their expiry date and every single one still reads valid.

What is the global online gambling market worth in 2026?

The most defensible answer is a range with two different meanings attached to it. H2 Gambling Capital, the dataset most of the industry prices deals against, puts global online gambling at $293bn in gross gaming revenue for 2024, its latest actual year. Grand View Research puts the "online gambling market" at $88.0bn for 2025 and $97.7bn for 2026. Mordor Intelligence says $107.36bn for 2025. Precedence Research says $88.04bn for 2025.

Those are not four opinions about one quantity. H2 states its metric: gross gaming revenue, stakes minus winnings paid out. Grand View, Mordor and Precedence say "revenue" or "value" and never state whether they mean GGR, net revenue after bonuses, or consumer spend. Until a publisher names its metric, its number cannot be compared with one that does.

So: if you want the figure the industry itself works from, it is $293bn GGR for 2024. If you want the figure that dominates search results, it is around $88–108bn for 2025. The gap between them is not a disagreement about the world. It is a disagreement about the question.

What the four words actually mean

Almost every argument about the size of this industry collapses once these are separated.

The recycling effect is why turnover figures sound enormous. A player who deposits $100 into a slot with a 96% return can place several thousand dollars of stakes before the balance is gone. Handle counts all of it. GGR counts the $100.

What do regulators actually report?

Regulator returns are the only layer in this topic that consists of reported figures rather than models, and they cover a minority of the world. Where they exist, they are the floor everything else should be checked against.

The UK Gambling Commission publishes the cleanest series. For the financial year April 2024 to March 2025 it reports £7.8bn of gross gambling yield from remote casino, betting and bingo, against £16.8bn for the whole customer-facing GB industry. UKGC defines remote as gambling by "the use of remote communication using the internet, telephone, television, radio", and has counted overseas operators serving GB customers since November 2014. It also warns that it revises the last three years, so recent figures are provisional.

Read that table with the fiscal years in mind. UKGC and Ontario run April to March; everyone else runs calendar years. They do not belong in a single column labelled 2025.

Two regulators are worth naming for what they do not publish. The Malta Gaming Authority, which licenses a large share of the European online industry, publishes gross value added to the Maltese economy (€1,422.0m for 2025) and licence counts, but no remote GGR at all. Any "Malta online GGR" figure in circulation is not an MGA number. And Italy's ADM publishes online raccolta of €109,318m for 2025, which is money staked, not revenue, and roughly forty times the Spanish revenue figure above for reasons that have nothing to do with market size.

How much has online gambling grown?

Faster than the land-based industry, and the only way to show it honestly is with one publisher's series rather than a stitched-together chart.

Here is UKGC remote GGY across six financial years, taken from UKGC annual publications only.

Three caveats travel with that table. The 2020-21 spike is land-based closure during the pandemic, not online growth, and UKGC states it would not expect the pandemic period to be comparable with what came before. The share column is our arithmetic on UKGC's rounded headline figures, not a UKGC statistic, except for the year UKGC published the share itself. And UKGC changed how operators file regulatory returns in July 2024, inside the most recent year shown.

Growth over the full period is real and unspectacular in any single year: remote GGY rose from £5.7bn to £7.8bn across six financial years, about 37%. The last year alone added more than £900m.

For a global growth rate you are back in vendor territory, where the forecasts run between roughly 11% and 12% a year and nobody publishes what they are compounding.

What share of gambling is now online?

Between 39% and 73%, and the number you get depends almost entirely on the denominator.

• Europe: 39% of gambling GGR in 2024, from EGBA's Key Figures 2025 edition. That figure is produced by H2 Gambling Capital, covers EU-27 plus the UK, and EGBA labels it provisional and subject to revision. It belongs in the vendor layer with a trade-body byline, not alongside regulator returns.

• Great Britain: 46.4% of all GGY including lotteries, or 61.9% of the £12.6bn GGY excluding lotteries. Same year, same regulator, same online figure, twenty-two points apart.

• Denmark: 73% of all gambling in 2025 occurred "on computers or mobile devices", up from 70% in 2024.

• Sweden: 66.5% of the licensed market in Q1 2026, on our arithmetic from Spelinspektionen's quarterly figures.

Any cross-country online-share comparison that does not state how lotteries are treated is not a comparison. This is the single most common error in the statistics pages that rank for these queries.

Which segments are actually growing?

Online casino leads, sports betting follows, poker is the slowest everywhere it is measured separately. The problem is that "online casino" means four different things in four regulators' hands.

On poker, the received wisdom needs qualifying. It is shrinking in Denmark (DKK 125m in 2022 to 105m in 2025) and Spain (−4.6% in 2025), flat in Ontario, and growing in France, up 6.5% in 2025 to €525m, where tournaments rose while cash games fell. H2's European forecast has poker growing at 2.3% a year to 2029, the slowest of six online verticals but not a decline. "Poker is dying" is not supported by any source with a number attached.

The fastest-growing European online vertical in H2's forecast is not casino at all. It is online lottery, at 7.7% a year to €10.4bn by 2029.

How many people gamble online?

About 7.8% of adults, and the widely-quoted headcount that follows from it should be treated with suspicion.

The underlying figure is solid. A 2024 systematic review and meta-analysis in Lancet Public Health, pooling 131 adult samples, found 7.8% of adults (95% CI 6.2–9.5) reported gambling online in the past 12 months, and 13.3% among people who gamble at all. Among adolescents the figure was 10.3%.

The absolute number is where it goes wrong. The Lancet authors deliberately converted prevalence into headcounts for gambling overall (2.3 billion adults), for any-risk gambling and for problematic gambling, using region-by-region population weighting. They published no headcount for online gambling. Neither does the WHO, whose gambling fact sheet gives no online figure of any kind.

The figure of "388 million online gamblers" circulates widely. We could not find it in any peer-reviewed or institutional source. Worse, it does not reproduce from the Lancet's own arithmetic: dividing the study's published headcounts by its published prevalences implies an adult base near 5.08 billion, which at 7.8% gives roughly 396 million, not 388 million. To land on 388 million you need an adult population about 106 million below the one the study used.

Our position: publish the prevalence, not the headcount. If a headcount is needed, carry the published confidence interval through it and say whose arithmetic it is. On the Lancet's implied base, 6.2% to 9.5% gives a range of roughly 315 million to 485 million adults, and that is our derivation, not the study's. A three-digit point estimate inside a 170-million-wide interval is false precision.

How big is crypto gambling?

Somewhere between $6bn and $81bn a year in revenue, which is the widest credible range in this entire page, and the reason is worth understanding.

The $81.4bn figure comes from one vendor, Yield Sec, reported by the Financial Times in April 2025 as crypto wagers generating "$81.4bn in gross gaming revenue" for 2024. Every "$81bn crypto casino" headline traces back to that single article. There is no second independent source.

Two problems sit under it. Yield Sec's own published methodology describes a proprietary "Value Per Visit" model built from surveillance of search, sites, apps, ads and social traffic. It is a traffic-derived model output that media then labelled with an accounting term. And the number does not survive arithmetic: all of European online gambling, legal and every vertical, was €47.9bn GGR in the same year. A crypto-only figure 1.7 times larger than the entire European online market leaves very little room for everyone else.

Two counter-measurements exist, both lower by roughly an order of magnitude. Gambling Insider tracked 29 labelled hot wallets belonging to 12 crypto casinos across Ethereum, BNB Chain and Tron, and measured $22.7bn of deposits in 2025, of which Stake accounted for $15.2bn. Converting deposits to revenue at 25 to 50 cents per dollar deposited gives $5.7bn to $11.4bn of GGR. Tanzanite, working the same way across 90-plus wallets, arrived at $10–11bn for 2024. Both note that Bitcoin and Litecoin deposits are invisible to the method, as is anything routed through a payment processor, so these are floors rather than totals.

Stake's own numbers are company claims. The FT reports 25 million users, 300 billion bets since 2017 and $4.7bn of GGR in 2024, all "according to the company", and the source does not say whether the user figure means registered accounts or active players.

One more attribution point that matters for anyone citing this segment: Gaming Compliance International acquired Yield Sec in November 2025. GCI's subsequent figures are the same data lineage under a new name, not independent corroboration of it.

What we can measure ourselves

Nobody can count offshore revenue from outside. What can be counted is the licensing surface the offshore industry runs on, and we read those registers in full and on a schedule.

We have read Anjouan three times this month, which is the only way to tell growth from noise.

The register grows faster than it is cleaned, and its status column carries no information because it never varies. Method and per-row findings are in our Curaçao register census and in our note on what an Anjouan licence does when a casino will not pay. The same check run against a single operator rather than a whole register is set out in how to check a crypto casino licence.

This is not a revenue estimate and we are not going to convert it into one. It is a count of the permission layer: roughly 2,150 licences and over 4,000 domains registered across the two jurisdictions that host most of the crypto-facing industry. Anyone modelling this segment should have to reconcile against it.

Which regions can actually be measured?

Europe and North America, partially. The rest is estimate or silence.

The absence in the last two rows is a finding, not a gap in our searching. The only large Asia-Pacific regulator publishing an online-labelled revenue line is the Philippines' PAGCOR, and its "E-Games and online gaming" segment explicitly includes onsite poker and bingo grantees, which is land-based product inside an online heading. Japan's largest online casino activity is illegal, so it exists only as a police estimate of roughly 3.37 million users in 2024.

Even the measured markets admit a hole. Sweden's regulator puts channelisation at 84% for 2025 and states plainly that every such measure is an estimate, because there is no complete data on what Swedes stake outside the licence system.

What the forecasts say, and what they are worth

Every credible forecaster expects online to keep taking share from land-based. None of them agrees on the size of what is growing.

The single most quotable forecast in the industry is H2's: online gambling passes half of all global gambling revenue in 2029. It is also the only forecast on this page whose publisher states what it is forecasting.

Grand View's $202.8bn for 2033 has no independent corroboration we could find, and Grand View's own earlier edition forecast $153.57bn by 2030 at a different CAGR. Treat single-vendor long-horizon points as scenarios with a publisher attached, not as measurements of the future.

What would it take to answer this properly

A short list, because it explains why this page is built the way it is.

Regulators would have to publish online GGR on a common definition with a stated lottery treatment. Vendors would have to name their metric. The offshore segment would need a measurement method that does not depend on a deposit-to-revenue ratio somebody assumed. And the headcount question would need a study that converts online prevalence into a population estimate the way the Lancet team did for gambling overall.

Until then, the correct answer to "how big is online gambling" is a sentence with three parts: a number, the thing it counts, and the year. Anything shorter is a guess wearing a decimal point.

Methodology and definitions

What we did. We opened each source cited on this page and recorded the figure, its unit, its period, whether the publisher calls it actual, provisional, estimate or forecast, and the publisher's own definition of what is being measured. Where a figure is our arithmetic on published inputs, it is labelled as derived in the sentence that carries it. Where a widely-circulated figure has no traceable publisher, we say so instead of repeating it.

What we would not do. We did not convert between currencies, because the rate date changes regional rankings. We did not blend vendor estimates into an average, because averaging figures with undeclared metrics produces a number that measures nothing. We did not build a single time series across publishers or across editions of the same publisher. We did not present any forecast as a fact.

Definitions used above. GGR / GGY: stakes minus winnings paid out, before costs and tax. Turnover, handle, raccolta, amount staked: the sum of all bets placed, including re-staked winnings. Deposits: money moved onto a platform. Net revenue: GGR after bonuses and eligible deductions. Remote: the UK regulator's term for gambling conducted by electronic communication, which is broader than "online". Channelisation: the share of a national market flowing through licensed operators.

Update policy. This page carries a fact-check date. The figures most likely to move within a year are the UKGC annual series, whose next release is scheduled for 17 September 2026, the EGBA European figures, currently in their 2025 edition covering 2024, and our own register counts, which we re-read on a schedule. We update figures and the year in the title, and we do not change this URL.

Where our own figures come from. The register counts on this page are our full reads of the public registers, recorded against the profiles in the BullsRank catalogue. The rules we apply to sourcing and dating are set out in our methodology.
