What Is iGaming? A Complete Guide
iGaming is the business of online gambling: sports betting, casino, poker and more, plus the operators, suppliers and regulators behind it. This is the complete beginner-to-professional guide.

"iGaming" is the term the industry uses for online, real-money gambling and the entire business built around it. If money is staked on an uncertain outcome through a screen rather than across a counter, it sits somewhere inside iGaming. This guide explains what that covers, how the industry is structured, how the money works, and the language you need to follow it.
What iGaming actually means
At its simplest, iGaming is gambling delivered over the internet. That includes:
- Sports betting, wagering on the outcome of sporting events, in advance or live in-play.
- Online casino, digital versions of slots, roulette, blackjack and other table games.
- Live casino, real dealers streamed to players in real time.
- Online poker, player-versus-player games run by an operator that takes a cut.
- Bingo, lottery and instant-win games delivered online.
- Emerging formats such as prediction markets and event-based contracts, which sit at the regulated edge of the sector.
The word is used loosely. Some people use "iGaming" to mean only online casino and reserve "sports betting" as a separate category. In practice the industry, its conferences and its trade press treat iGaming as the umbrella for the whole online real-money ecosystem, and that is how we use it.
How the industry is structured
The most useful thing a newcomer can learn is that iGaming is not one type of company. It is a value chain, and money and expertise flow along it.
- Operators run the brands players actually bet with. They hold the licences, take the bets, manage the risk and own the customer relationship.
- Platform and B2B providers supply the technology operators run on: the player account system, wallet, payments integration and back office.
- Game studios and content suppliers build the slots, table games and live-casino content that operators put in front of players.
- Data and sports-data companies supply the odds feeds, live scores and integrity services that betting depends on.
- Affiliates and marketing partners send players to operators in exchange for a share of the revenue or a fee.
- Payment providers move money in and out, a genuinely hard problem in a regulated, cross-border industry.
- Regulators license operators, set the rules and enforce them.
A single large group may span several of these layers, which is exactly why the biggest companies are so big. Understanding which layer a company sits in tells you how it makes money and who its customers are.
How the money works
Every gambling product is built with a mathematical edge in favour of the operator. Over enough bets, the operator keeps a predictable share of everything staked. The headline numbers to know:
- Gross Gaming Revenue (GGR) is total stakes minus winnings paid back to players. It is the industry's top line.
- Net Gaming Revenue (NGR) is GGR minus bonuses and certain costs, and is closer to what the operator actually earns before tax.
- House edge is the theoretical share of each stake the operator expects to keep; hold or margin is what it actually keeps in practice.
Casino products carry a higher, steadier margin because the edge is fixed in the game maths. Sports betting runs on a thinner, more volatile margin. Suppliers, studios and affiliates all earn a slice of the same underlying player spend, which is why owning more than one layer of the chain is so valuable.
Regulation is the defining force
More than any product feature, regulation shapes iGaming. Whether a company can operate in a country, what it can offer, how it must protect players and how much tax it pays are all set by regulators, and they differ enormously from one market to the next.
- Some markets are regulated and licensed, with a local authority overseeing operators.
- Some are grey, where the law is ambiguous.
- Some are prohibited, where offering gambling is illegal.
Because each country decides for itself, iGaming is really a patchwork of national markets rather than a single global one. A brand can be fully licensed in one country and unwelcome in its neighbour. The clearest trend of the last decade is the steady move toward local licensing as more countries build their own regimes.
Responsible gambling
Real-money gambling carries real risk of harm, and modern regulation treats player protection as a core obligation rather than an afterthought. Licensed operators are expected to offer deposit and loss limits, self-exclusion, and to monitor play for signs of harm and intervene. For anyone working in the industry, responsible gambling is not a compliance box, it is part of the licence to operate.
The language you will hear
A few terms recur constantly:
- Operator, supplier, affiliate: the three roles most companies fall into.
- B2B and B2C: business-to-business (selling to operators) versus business-to-consumer (selling to players).
- GGR and NGR: the revenue lines above.
- Channelisation: the share of gambling that flows through licensed operators rather than the black market, the key measure of whether regulation is working.
- KYC and AML: know-your-customer and anti-money-laundering, the identity and financial-crime checks every licensed operator must run.
Where to go next
iGaming rewards people who understand it a layer deeper than the headlines. From here, the natural next steps are understanding how regulation works across markets, how companies actually make their money, and, if you are considering the industry as a career, how to break into it. Our guides cover each of those in turn.
