How to Start an Online Casino or Sportsbook

"How to start an online casino" is one of the most searched questions in the industry and one of the worst answered, because most of the answers are written by companies selling a platform or a licence. This guide is the neutral version: what an online gambling business actually consists of, the decisions in the order you have to make them, what each costs, how long it takes, and why most new operators fail. It applies to casinos and sportsbooks alike; the differences are flagged where they matter.

What you are actually building

An online casino or sportsbook is five businesses stapled together: a licensed legal entity, a technology platform, a content supply (games or a sportsbook feed), a payments and identity operation, and a marketing machine. The operator's own value is in the last of these and in the brand; almost everything else can be bought. The strategic question at the outset is therefore not "how do I build a casino" but "which of these do I own, which do I rent, and in which market".

The economics that everything hangs on: gross gaming revenue (stakes less winnings) is typically 3 to 5 per cent of casino turnover and 5 to 10 per cent of sports turnover, before bonuses, tax, platform fees, game supplier fees and payment costs. What is left, net gaming revenue, has to cover acquisition and operations. A new operator's acquisition cost per depositing customer in a competitive regulated market runs to several hundred pounds, euros or dollars, and that customer takes months to pay it back. The business is capital-intensive at the start and cash-generative only at scale, which is why the first decision is the market.

Step one: choose the market and the licence

The market determines the licence, the tax, the product rules, the marketing rules, and the competition, so it is chosen first and everything else follows.

Regulated national markets (Britain, most of Europe, Ontario, the American states, Brazil since 2025) require a local licence, tax gaming revenue at rates from single digits to over 40 per cent, restrict products and marketing, and offer legal certainty, bankable revenue and access to mainstream payments and advertising. Entry is slow (six months to two years), expensive (licence fees, local substance, capital requirements) and demanding (a compliance function from day one). The Gambling Licensing Jurisdictions Compared guide sets the options side by side.

Multi-jurisdiction hub licences (Malta for Europe, the Isle of Man, Gibraltar) let an operator serve markets that do not have their own regime, under a respected regulator, with EU or Commonwealth legal standing. They do not license you into markets that regulate locally; a Malta licence does not permit British or German customers.

Offshore licences (Curaçao under its 2024 reform, Anjouan, Kahnawake) are fast and cheap to obtain and permit operation into grey markets, where gambling is neither licensed nor effectively prohibited. Payments, advertising and banking are harder; the revenue is less bankable; and the direction of travel in every major market is toward enforcement against operators serving their residents without a local licence. The Offshore Gambling Explained guide covers the model honestly.

A common structure for a new operator is a hub or offshore licence for launch and grey markets, followed by local licences in the two or three regulated markets that prove out. The trap is building the whole business on grey revenue that a regulator can remove with a blocking order.

Step two: the entity, the people and the money

The licence attaches to a company, and regulators license the company's owners and controllers as much as the company. Expect to provide identification, source of wealth and source of funds for every beneficial owner above a threshold (typically 10 per cent), criminal record checks, financial statements and a business plan. Regulated markets require local substance: a registered office, resident directors or key officials, and in some cases local employees. Several markets require a bank guarantee or paid-up capital to cover player balances.

Player funds must be protected. Britain's regime requires operators to state the level of protection; most European regimes require segregation; the American states require reserves. Design the treasury for this from the start.

The people a new operator cannot launch without: a licensed key official or compliance officer (regulators name the role and vet the person), a money-laundering reporting officer, a head of payments and risk, a marketing lead who knows the market's rules, and someone who owns the product. Everything else can be outsourced initially.

The money: a realistic budget for a regulated-market launch is in the low millions, with licence and legal costs of tens to hundreds of thousands, platform set-up and integration in the same range, a marketing budget that dwarfs both, and eighteen months of operating losses before break-even. An offshore or grey-market launch on a white-label platform can be done for a fraction of that, and the reduced cost buys a correspondingly reduced business. The How iGaming Companies Make Money guide is the model to build the plan on.

Step three: the platform decision

The platform is the account management system, wallet, payments orchestration, game aggregation, bonus engine, CRM hooks, reporting and back office. Three ways to get one:

White label. You operate under the platform provider's licence, on its infrastructure, with your brand on the front end. Fastest and cheapest to launch (weeks; a set-up fee and a revenue share of 10 to 30 per cent), but you do not hold the licence, you do not own the customer data in any meaningful sense, and you cannot leave without starting again. Suitable for testing a brand or a market; unsuitable as the foundation of a business you intend to own.

Turnkey. You hold the licence; the provider supplies the platform, integrations and often the games, on a licence fee plus revenue share, and you operate it. Months to launch; you own the customers and the licence; you depend on the provider's roadmap.

Proprietary. You build or buy the core and integrate the rest. The choice of operators at scale, because the platform becomes the competitive advantage, and a mistake for a new operator, because it takes a year and a team before a single bet is placed. The White Label vs Turnkey Platforms guide sets out the trade-offs in detail.

Whatever the choice, the platform must be certified for the market (regulators test the platform, the RNG and the wallet), must support the market's product rules (stake limits, session reminders, deposit limits, self-exclusion integration) and must give you your own data.

Step four: games and the sportsbook

Casino content comes from game studios, usually through an aggregator that integrates hundreds of studios behind one API. The operator pays a revenue share on each game's GGR (commonly 8 to 15 per cent, higher for premium content and live dealer) plus minimum monthly fees. A launch lobby of a few hundred games from a dozen studios is normal; the games that matter are the twenty that produce most of the revenue in the target market, and an operator should know which those are before signing. Live dealer is supplied by a small number of studios and is the highest-margin category for them. Every game must be certified for the market by an approved testing laboratory, and jurisdictions maintain lists of approved suppliers. The How Online Slots Work and RTP, House Edge and Margin guides explain the product.

A sportsbook is harder to run than a casino because the operator is pricing risk in real time. A new sportsbook buys a managed trading service (odds, risk management and settlement supplied by a B2B provider that runs the book for many operators) or a full sportsbook platform with data feeds, and then decides how much of its own trading to layer on top. The provider's margin and the operator's risk appetite are the two negotiations. The How Bookmakers Set Odds and Make Money guide explains the economics.

Step five: payments, identity and risk

Payments are the operational core of an online gambling business and the place new operators most often stall. You need an acquirer willing to process gambling (a restricted merchant category that many banks refuse), a payment orchestration layer connecting cards, bank transfers, open banking, e-wallets, vouchers and local methods for each market, and a payout process fast enough to compete. Regulated markets restrict methods (Britain bans credit cards; several markets restrict crypto), and processing costs for gambling run well above ordinary e-commerce. The Payment Methods in iGaming guide covers each rail.

Identity and anti-money-laundering are licence conditions. Age and identity verification before play or before withdrawal, depending on the market; customer due diligence and enhanced checks at thresholds; source-of-funds enquiries; sanctions and politically-exposed-person screening; suspicious activity reporting. The KYC and AML Checks guide explains the obligations, and the AML and Financial Crime course is the training.

Fraud (bonus abuse, multi-accounting, chargebacks, stolen cards, arbitrage) is a permanent tax on the business, managed by the risk team with rules, device fingerprinting and manual review. The Fraud and Risk Management course covers it.

Step six: compliance and responsible gambling

A regulated operator needs a compliance function before it needs customers. The licence conditions, the market's advertising code, the responsible-gambling requirements (deposit limits, reality checks, self-exclusion integration with the national scheme, affordability or spend checks in Britain and the Netherlands, interaction with at-risk customers), data protection, and the reporting obligations all have to be designed into the platform and the operation. The iGaming Compliance Checklist is the working list, and the Responsible Gambling Tools Explained guide covers the player-facing tools.

Regulators fine operators for failures in this area more than any other, and new operators are watched closely because their controls are untested.

Step seven: marketing and acquisition

Acquisition in regulated markets runs through affiliates (comparison sites and creators paid per customer or on revenue share), paid search and social within the platforms' gambling policies, sponsorship and media where advertising is permitted, and CRM to retain what was acquired. Every channel is constrained by the market's advertising rules, which govern bonuses, audiences, timing and content, and which reach the operator's affiliates as well as its own marketing. The Affiliate Programmes Explained guide covers the channel that most new operators lean on first, and the Marketing Compliance course covers the rules.

The bonus is the acquisition tool that regulators most restrict and that costs the most. Brazil prohibits sign-up bonuses; Ontario prohibits public inducements; Britain has tightened the terms; several European markets cap or ban them. A business plan that assumes a bonus-led launch should be checked against the target market's rules before it is written.

The timeline

For a regulated-market launch on a turnkey platform: market selection and business plan (one to two months); entity, key people and licence application (three to twelve months, in parallel with platform contracting); platform set-up, integrations, game certification and regulator testing (three to six months); payments onboarding (two to four months, often the critical path); marketing preparation and affiliate recruitment (two months before launch). Nine to eighteen months from decision to first bet is realistic; six is exceptional; twenty-four is common in the American states.

For a white-label launch under an offshore licence: four to twelve weeks, and the business you have at the end is correspondingly limited.

Why new operators fail

The pattern is consistent. Underestimating acquisition cost and overestimating customer value, so the plan runs out of money before the book is large enough. Building on grey-market revenue that a regulator or a payment provider removes. Choosing a white label for speed and discovering that there is no exit. Launching without a compliance function and drawing a regulator's attention in the first year. Copying an established operator's lobby and bonus and offering no reason to switch. Treating payments as a supplier problem rather than the core operation. Having no differentiation in a market where every competitor has the same games from the same studios.

The operators that succeed pick a market they understand, a niche within it (a product, an audience, a region, a brand voice), build the compliance and payments operations properly, treat the platform as rented until they can afford to own it, and spend the marketing budget on retention as much as acquisition.

Frequently asked questions

How much does it cost to start an online casino? From tens of thousands for a white label under an offshore licence to low millions for a regulated-market launch. The licence and platform are a minority of the cost; marketing and operating losses to break-even are the majority.

Can I start an online casino without a licence? Not lawfully in any market this site covers. Operating without a licence is an offence in regulated markets and, in grey markets, leaves you without banking, payments, advertising or legal recourse.

Which licence is easiest to get? Offshore licences (Curaçao, Anjouan, Kahnawake) are the fastest and cheapest. "Easiest" is not "best": what the licence lets you do, where, and with which payment providers matters more than the application.

Do I need my own games? No. Almost every operator licenses games from studios through aggregators. Proprietary content is a differentiation strategy for later, not a launch requirement.

How long until an online casino is profitable? Eighteen months to three years for a regulated-market operator with a sound plan; many never reach it. Faster in grey markets, with less certainty that the revenue lasts.

Is a sportsbook or a casino easier to start? A casino: the content is bought, the margin is built into the games, and there is no real-time risk. A sportsbook needs trading, data and risk management, usually bought as a managed service at first.
