Operator
The company that runs a gambling site or app — it holds your account, accepts your bets, and pays out any winnings.
Definition
An operator is the licensed business that offers gambling services directly to players under its own brand — running an online casino, sportsbook, or poker room, holding customer funds, accepting stakes, and paying winnings. It carries the regulatory responsibility for the service, including licensing, KYC (identity checks), AML (anti-money-laundering), and responsible-gambling obligations. Most operators do not build the games themselves; they license content from game studios (often via an aggregator or platform provider) and connect payment providers, all under the terms of a licence from one or more gambling regulators. The same company may run several brands, and its role is distinct from suppliers (who make the games and technology) and affiliates (who market on the operator's behalf).
Worked example
An operator runs an online casino under a national licence. In one month, players stake £10,000,000 on a slot with a 96% RTP, which by definition carries a 4% house edge (RTP + house edge = 100%). Over the long run the game is expected to return about £9,600,000 in winnings, leaving roughly £400,000 as Gross Gaming Revenue (GGR = stakes − winnings paid = £10,000,000 − £9,600,000). After the operator deducts, say, £40,000 in bonuses granted, £84,000 in gaming duty, and £26,000 in payment and game-provider fees, its Net Gaming Revenue (NGR) is about £250,000 — the figure it actually books and from which it pays suppliers and affiliates. Note that a single month's real result varies around the theoretical 4% because of short-term variance; the 96% RTP describes only the long-run expectation.
Why it matters
The operator is the party a player actually deals with: it holds the money, sets the terms and conditions, and is accountable for fairness, licensing, and player protection — so knowing who the operator is (versus the studio that merely made a game) tells you who to complain to and which regulator covers you. For professionals, the operator is the central commercial node of the industry, where licences, revenue (GGR and NGR), player data, and compliance duties all sit; business models and cost structures — gaming taxes, provider revenue share, affiliate payouts — are built around it.

Note: The core relationships are stable definitions: RTP + house edge = 100%, and GGR = stakes − winnings paid. However, the exact NGR formula varies by operator and jurisdiction — which items are subtracted from GGR (bonuses, taxes, fees, affiliate/provider commissions) is not standardised. The example's tax figure is illustrative; real gaming-duty rates differ widely by jurisdiction (for instance, the UK's Remote Gaming Duty was 21% in the mid-2020s and is subject to change). The split of roles also varies: a minority of operators build some of their own games rather than only licensing them, and terms like "operator," "platform," and "white-label provider" can overlap in practice.
