Aggregator
A company that connects an online casino to many game studios through a single technical integration, so the operator can offer thousands of games without integrating each provider one by one.
Definition
An aggregator is a middleware layer in the iGaming supply chain that sits between game content providers (studios like Pragmatic Play, Play'n GO, NetEnt) and operators (the casino brands players see). Instead of an operator building and maintaining a separate API integration, wallet connection, and reporting feed for each studio, it integrates once with the aggregator and gains access to the aggregator's entire portfolio of games. The aggregator handles game delivery, a unified remote gaming server (RGS) or transaction interface to the operator's wallet, session and round management, consolidated reporting, and often value-added services such as bonus/free-round tools, jackpots, tournaments, and certification support. Aggregators typically earn a revenue-share fee taken from the content, which is split with the studios; they generally do not hold the players' funds or the gambling license themselves.
Worked example
Suppose an operator wants to launch a casino lobby with 6,000 slots and live tables from 40 different studios. Integrating each studio directly might take weeks of engineering per provider and 40 separate wallet and reporting connections. By integrating with a single aggregator, the operator completes one certified API integration and instantly lists all 40 studios. On the commercial side, imagine a studio's slot with an RTP of 96% (so a 4% house edge, since RTP + house edge = 100%). Over a month it takes EUR 1,000,000 in stakes and pays EUR 960,000 in winnings, producing GGR of EUR 40,000 (GGR = stakes minus winnings paid). If the total content revenue-share rate is 12% of GGR, that is EUR 4,800; the aggregator might keep, say, 3 percentage points (EUR 1,200) and pass 9 points (EUR 3,600) to the studio, with the exact split set by contract. Note that the operator's NGR on this activity would be lower still, because NGR = GGR minus bonuses, fees, and gaming taxes.
Why it matters
Aggregators are the connective tissue of the modern iGaming ecosystem: they explain how a mid-size casino can offer tens of thousands of games it did not build and could never integrate one by one. For professionals, understanding the aggregator layer clarifies where margin is taken (the content revenue share is split between studio and aggregator before the operator's own costs), who is responsible for what in the game round (delivery, wallet calls, reporting, certifications), and where operational and compliance risk sits. It also matters for player protection and integrity: because one aggregator can push content and configuration to many operators at once, its handling of certification, RTP configuration, and responsible-gambling tooling has an outsized effect across multiple brands and markets.

Note: The revenue-share percentages and 3/9-point split in the example are illustrative only and vary widely by contract, studio tier, volume, and market; verify against actual agreements. Whether an aggregator holds any license or funds depends on jurisdiction and business model (some are pure B2B middleware, others hold B2B supplier licenses). The GGR/NGR/RTP relationships are stable definitions, though the specific items deducted to reach NGR (which bonuses, fees, and taxes) vary by operator and regulator.
