The global online gambling market reached USD 78.14 billion in 2024 and is projected to hit USD 227.36 billion by 2033 at a compound annual growth rate of 12.6%. I’ve watched this market evolve from a niche digital curiosity into one of the fastest-growing entertainment verticals worldwide, and the story of that growth is inseparable from the story of payment innovation. Every barrier removed from the deposit process — every new method, every faster settlement, every privacy-preserving option — has translated directly into market expansion.

This article maps the global market’s current size, the dominance of sports betting as a segment, how payment technology is accelerating growth, and where regional dynamics are shaping the industry’s future.

Global Market Size and Revenue Breakdown

Two sets of numbers frame the scale. The online gambling market specifically — sports betting, online casino, poker, lottery, and other digital formats — stood at USD 78.14 billion in 2024. The total global gambling market, including land-based casinos, physical sportsbooks, and retail lottery, reached $574.55 billion in 2025, with forecasts pointing to $728.79 billion by 2030 at a CAGR of 4.6%.

The gap between online growth (12.6% CAGR) and total market growth (4.6% CAGR) tells the real story: the industry isn’t just growing — it’s migrating online. Digital channels are absorbing share from physical venues at an accelerating rate. Global gambling industry revenues hit $347 billion in 2024, reflecting 18% year-over-year growth across the 2020-2024 period, with the online segment capturing a disproportionate share of that expansion.

For payment companies like Paysafe Group, the migration from physical to digital gambling creates compounding demand. Every punter who moves from a TAB counter to a betting app needs a digital deposit method. Every market that legalises online gambling generates a new cohort of first-time digital depositors. The payment infrastructure serving this transition isn’t a support function — it’s an enabler that directly influences how fast the migration can occur.

Sports Betting as the Dominant Online Segment

Within the broader online gambling market, sports betting generated USD 44,196.6 million in revenue in 2024 — making it the single largest online segment by a comfortable margin. That dominance reflects both the global popularity of sports and the behavioural pattern of sports bettors: they deposit regularly, engage with multiple events per week, and maintain accounts across competitive seasons that span months.

Australia contributes approximately 4% of global gambling revenue, an outsized share for a country with less than 0.4% of the world’s population. Within that Australian contribution, sports betting — horse racing, AFL, NRL, cricket, soccer — drives the online component. The cultural integration of betting with sport in Australia creates a market density that few other countries replicate.

The sports betting segment’s growth is fuelled by live market expansion, same-game multi-bet products, and the proliferation of betting markets across previously niche sports and esports. Each new market type creates additional deposit occasions — a punter who previously bet once a week on AFL might now deposit separately for midweek international soccer and weekend esports tournaments. That increased deposit frequency compounds the demand for fast, flexible, and user-friendly payment methods.

For prepaid vouchers specifically, sports betting’s seasonal rhythm creates predictable demand patterns. Major events — football World Cups, Grand Slams, racing carnivals — generate deposit spikes that prepaid users plan around by purchasing vouchers in advance. The fixed-denomination model suits event-based budgeting better than it suits continuous, high-frequency wagering, which is why prepaid adoption in sports betting tends to concentrate around casual and budget-conscious bettors rather than the high-volume end of the market.

Payment Innovation Driving Market Expansion

Embedded finance in payments reached $6.5 trillion in volume by 2025 — a number that dwarfs even the gambling industry’s considerable size. The principle behind embedded finance is simple: payment functionality woven into the point of experience rather than bolted on as a separate step. For gambling, that means deposit methods that feel native to the betting app rather than requiring a detour to a bank portal or a trip to a newsagent.

Paysafe CEO Bruce Lowthers has positioned the company’s white-label wallet as a response to this trend — a product that lets operators embed wallet functionality directly into their platforms under their own brand. The concept takes the Skrill/Neteller model and makes it invisible to the end user: the punter deposits through what looks like the bookmaker’s own wallet, but the infrastructure underneath is Paysafe’s. That kind of payment embedding accelerates market growth because it removes a friction point — the deposit step — from the user journey.

Digital wallets, real-time bank transfers (like Australia’s PayID), prepaid vouchers, and cryptocurrency each serve different market segments, but their collective effect is to broaden the addressable market. A punter who won’t share bank details online can deposit with Paysafecard. A punter who wants instant withdrawals uses PayID. A punter in an underbanked market uses mobile money. Each payment innovation opens a door that was previously closed, and each opened door admits new depositors into the market.

The relationship between payment innovation and market growth is measurable. Markets that legalise online gambling see the fastest adoption where payment infrastructure is already mature. Australia, with its advanced digital payment ecosystem — USD 142.7 billion in digital payments in 2025 — adopted online gambling rapidly precisely because the payment rails existed. Emerging markets with less developed payment infrastructure grow more slowly, even when legal frameworks are permissive.

Regional Dynamics — Where Growth Is Fastest

North America is the headline growth region. US state-by-state legalisation has created a rolling expansion that’s been running for several years and still has significant runway. Each new state that legalises online sports betting creates a population-scale demand spike for deposit methods, and Paysafe’s Q4 2025 results — 6% organic growth in Digital Wallets led by North American iGaming — reflect that dynamic directly.

Europe remains the largest market by total revenue, with mature regulatory frameworks in the UK, Italy, Spain, and parts of Scandinavia. Growth rates are lower than in North America because the market is already well-developed, but the absolute revenue remains substantial. Paysafecard’s European roots — it originated in Austria — give it particularly deep penetration in this region.

Asia-Pacific is the region to watch. Australia leads in per-capita gambling expenditure, but markets like India, Japan, and parts of Southeast Asia represent enormous untapped potential. Regulatory frameworks in these markets are evolving unevenly — some are liberalising, others are tightening — but the demographic tailwind (large, young, digitally connected populations) creates growth pressure that regulation can channel but probably can’t contain.

Latin America and Africa are earlier-stage markets where mobile-first payment solutions are particularly important. In markets where traditional banking penetration is low, prepaid vouchers and mobile money become the primary deposit channels rather than alternatives. The growth in these regions won’t look like Australia or Europe — it will be shaped by the payment infrastructure available, and the operators who succeed will be those who integrate local payment methods rather than importing Western payment models wholesale.

Across every region, the pattern holds: gambling market growth follows payment innovation. Where deposits are easy, fast, and trusted, gambling participation increases. Where deposit friction remains — slow processing, limited methods, poor mobile experience — participation stalls regardless of regulatory openness.
