The international iGaming market has reached an era of many possibilities. As more countries step forward to license and regulate online gaming and betting, operators are increasingly seeking to expand beyond established bases in Europe and North America. 

To remain competitive, both B2B and B2C operators need to determine where player growth is most rapid and entry conditions are most receptive. This article discusses the top 5 growth markets for iGaming expansion in 2025–2026, covering the regulatory environment, demographics of players, technological preparedness and revenue potential of each market.

1. Brazil

In March 2023, its congress voted to pass legislation that would regulate online gambling in all its forms, opening the way to legalised sportsbooks and casino games. The step brought an end to years of grey‑market operation and provided a clear way forward for licensed operators. Brazil's population of more than 210 million, extensive smartphone usage and strong sports following make it appealing for both sports betting and live casino content.

Operators moving into Brazil need to contend with a licensing regime that stipulates physical presence and local partners. To simplify operations, many resort to API integration for casino products providing turnkey access to extensive game portfolios, risk‑management tools, and back‑office functions. Such APIs can manage regulatory reporting and responsible gambling requirements, enabling new entrants into the market of Brazil to concentrate on acquisition and marketing instead of developing infrastructure from the ground up.

2. Mexico

Mexico is another Latin American market that is opening up quickly. Though regulation has trailed, in 2024, the nation's gambling regulator started awarding permits for online sports betting and casino games. Mexico's 130 million population and consistently expanding internet infrastructure provide a lot of opportunity and iGaming revenues are expected to surpass multiple billions by 2026.

Localization is vital in Mexico. Content must resonate with local tastes. Football and boxing are the sports that generate the most betting interest in Mexico, and Mexican‑themed slot game titles find favor with players. A strong content pipeline via Hub88 can provide operators with both worldwide blockbuster titles as well as locally created content. Such a hybrid model of global and local content, along with payment integrations that are flexible to accommodate local e‑wallets and bank transfers, will be important to achieve market share.

3. Colombia

Colombia was one of the first countries in Latin America to regulate online gambling back in 2016. Since then, it has built a stable framework that balances consumer protection with commercial opportunity. Revenue in Colombia’s online gaming market reached billions of dollars, and it is expected to grow by a further 15 percent annually over the next two years. Colombian players are already accustomed to licensed offerings, making the market less risky for newcomers.

Critical to a successful entry is strong integration with local payment providers. Most operators in Colombia use an online casino content aggregator to launch new games rapidly and ensure compliance. Through a single API connection, they can control game updates, regional certifications, and promotional tools in one location. This saves time to market and prevents the complication of point‑to‑point integrations for every game provider.

4. Nigeria

Africa's most populous country, Nigeria, has seen booming interest in online casino games and sports betting. Although regulation is still patchy, an increasing number of state governments are considering licensing schemes. Boasting more than 220 million people and with mobile internet usage of nearly 60 percent, Nigeria is a huge audience of young, tech-savvy players. Football betting, live dealer blackjack and virtual sports are among the popular games.

Operators focusing on Nigeria need to optimize for mobile‑first experiences and low‑bandwidth conditions. Integrations via a solid API integration for casino partners provide fast delivery of game content, with adaptive streaming and AI‑powered upscaling for less interrupted play. Monetization models frequently revolve around low‑cost micro‑bets, daily rewards, and reward‑based advertisements.

5. India

India's iGaming situation is complicated. A patchwork of state‑level laws and regulations allows some states to legalize online bettings types such as horse racing, whilst others prohibit all online wagering. India's enormous population of 1.4 billion and its surging internet use make it a market that cannot be ignored. Forecasts predict that India's online gaming revenues will reach over USD 2 billion by 2026.

For operators, success will depend on selective market choice and content customization. API‑driven platforms, like hub88.io, enable fast game localization and compliance processes. They can be integrated with favourite UPI payments and local languages, offering smooth experiences to players in big metros and smaller cities. Analytics capabilities incorporated within such APIs enable providers to track player activity and modify bonuses, advertisements, and premium services in real time.

Drivers of Expansion

A number of shared drivers fuel expansion in these markets. Firstly, growing smartphone usage guarantees that more gamers can reach iGaming sites at any moment. Secondly, maturing payment infrastructures, ranging from Brazil's PIX to India's UPI, facilitate quick, safe deposits and withdrawals. Thirdly, regulators are increasingly acknowledging the tax and jobs gains of legal online gaming, so there are clearer licensing regimes.
