How iGaming Companies Make Money: The Economics of Online Gambling

An online gambling company makes money because the games are priced so that, across all players and over time, it keeps a predictable share of what is staked. That share is small per bet and enormous in aggregate, and everything about the business (the marketing, the bonuses, the technology, the compliance, the deals) is about attracting stakes and keeping that share intact after costs. This guide follows the money from the first bet to the bottom line, for operators, suppliers and affiliates.

The source: house edge and margin

Every gambling product has a built-in edge for the house. In casino games it is the gap between the true odds and the odds paid: a European roulette wheel has 37 numbers and pays 35 to 1 on a single number, so the house keeps 2.7% of stakes over time; slots are designed to a return-to-player (RTP) of 92% to 97%, so the house keeps 3% to 8%. In sports betting it is the overround: the implied probabilities across a market sum to more than 100%, and the excess (2% to 5% on a competitive football match, far more on parlays) is the bookmaker's margin. Poker and exchanges charge a commission (rake) instead. The RTP, house edge and margin guide covers the mechanics.

The edge is small per bet and the volume is large. A customer who stakes 1,000 over a month on slots at 96% RTP loses 40 in expectation; the operator's revenue from that customer is 40, whatever the customer's actual result that month.

From handle to revenue

The industry's revenue vocabulary:

Handle, stakes or turnover: the total amount wagered. The headline figure, and mostly returned to players.

Gross gaming revenue (GGR), or gross win: handle minus winnings paid out. What the operator kept. In sports betting, GGR divided by handle is the hold, and it fluctuates with results month to month around the structural margin.

Net gaming revenue (NGR): GGR minus bonuses and free bets given to customers, and usually minus gaming tax and sometimes platform and content fees. The revenue the business actually has to work with. The gap between GGR and NGR is 20% to 40% in promotional markets, which is why analysts distrust GGR-based claims.

A sportsbook with 1 billion of handle at 7% hold has 70 million GGR; after 15 million of bonuses and 14 million of gaming tax it has around 41 million NGR. The numbers scale, the ratios are the business.

Where the money goes

From NGR, an operator pays:

Gaming tax where not already deducted: on GGR in most modern regimes at rates from the low teens to over half, the largest single cost of being licensed. Some jurisdictions tax turnover instead, which destroys low-margin products.

Marketing: acquisition (affiliates, paid media, sponsorship, television) and retention (CRM, loyalty). Often 20% to 40% of NGR in competitive markets and far more in launch markets. The player acquisition guide explains the channels and the deals.

Content and data: revenue share to game studios (a percentage of the GGR their games produce, higher for live casino), sports data feeds and odds, and platform fees where the platform is licensed rather than owned.

Payments: processing fees, chargebacks, failed transactions, and the cost of local payment methods.

Technology and people: the platform, product development, trading, customer service and the compliance organisation, which grows with every market.

Licensing and compliance costs: fees, certification, audits, levies for research and treatment, regulatory settlements when things go wrong.

What remains is EBITDA. Mature, well-run operators earn 20% to 35% of NGR; suppliers earn more (the leading live casino supplier earns operating margins far above any operator); launch-market operators earn nothing for years.

Why launch markets lose money

Acquisition cost is paid up front and a customer's value arrives over years. In a newly regulated market every operator is buying customers at once, media and affiliate prices spike, and the arithmetic is that marketing exceeds revenue until the base matures. The US state-by-state launches were the largest demonstration: leading operators spent more on marketing than their total revenue for successive years, funded by public markets, in exchange for share. The bet pays if the customers acquired stay and the market's costs fall as competitors exit; it fails if acquisition costs stay high and retention is poor. Every new market (Brazil most recently) repeats the pattern.

Product economics

Products earn differently. Slots are high-margin and high-volume with predictable hold; live casino has higher player value and higher supplier cost; sports betting singles are low-margin and price-shopped; parlays and same-game parlays carry the highest margins because the margin compounds across legs; in-play carries more margin than pre-match. Operators steer customers toward higher-margin products through promotion and design, which is where regulators look hardest, and the product mix is a large part of why two operators with the same handle report different profits.

Poker and exchange products earn a commission rather than an edge: rake on each pot or a percentage of net winnings. They need liquidity (enough players to fill tables and match bets), which is why they concentrate in a few networks and why operators without liquidity offer them as a loss-leader for the customers they bring rather than as a profit centre in their own right.

How suppliers make money

Game studios and live casino sell on revenue share: a percentage of the GGR their content produces at each operator, with minimum guarantees and fixed fees for exclusive or dedicated content. Their cost is content development and, for live, studios and dealers; their revenue is a slice of every operator's revenue, diversified across markets, which is why they are valued more highly.

Platforms charge setup fees, monthly fees and revenue share for the account management and casino or sportsbook engines operators run on; sportsbook suppliers charge revenue share on betting GGR and fees for managed trading.

Data companies sell official data and odds on subscription and revenue share, and integrity services to sports bodies; their rights deals with leagues are the moat.

Payments companies take a percentage of transaction value and fixed fees; KYC and compliance vendors charge per check.

How affiliates make money

Affiliates are paid by operators for the customers they send: a fixed cost per acquisition, a revenue share (a quarter to a half of the net revenue those customers produce, for life), or a hybrid. Their costs are content, search optimisation and media; their asset is search rankings and audience. The largest are listed companies whose earnings move with operator commissions, search algorithm changes and advertising regulation.

What a good operator looks like in numbers

Reading a results announcement: handle growing with hold stable (not falling, which means either bad luck or pricing too keenly); NGR growing faster than marketing; acquisition cost per customer flat or falling with actives rising; a rising share of revenue from customers acquired more than a year ago (a retained base); product mix shifting toward higher-margin products without a rise in harm indicators; EBITDA margin expanding as markets mature; and a compliance record without settlements. The operators that show that pattern are the ones the market rewards, and the iGT 25 constituents' pages show which ones they are on any given day.

Frequently asked questions

How much does an online casino keep? Typically 3% to 8% of slot stakes and around 2.7% of roulette stakes over time, set by the games' RTP and rules.

What is the difference between GGR and NGR? GGR is stakes minus winnings; NGR deducts bonuses and, usually, gaming tax and platform fees. NGR is what the business lives on.

Why do gambling companies spend so much on marketing? Because the product is a commodity and the customer base is the asset; acquisition is the business, and in launch markets it exceeds revenue.

Are suppliers more profitable than operators? Usually. Their revenue is diversified across operators and markets, their capital intensity is lower and their margins higher.

What is hold? In sports betting, GGR divided by handle: the margin actually achieved after results, which fluctuates around the structural overround.
