How Online Casinos Manage Their Bankroll 

We chat with Hayden Bowman, Co-founder of iBankroll, to learn more about how online casinos manage their bankroll to ensure they always have enough cash to hand to pay out players.

Have you ever wondered how online casinos manage their bankrolls? On any given day, millions of pounds can pass through the casino, with players winning and losing all the time. 

Some days the casino can be up, others it can be down. But the online casino must always be able to pay out player winnings. 

This makes bankroll a critical aspect of running – and playing at – an online casino, and it’s why you should always play at brands holding an active licence from the UK Gambling Commission, as these sites must prove they can meet liabilities at all times. 

To learn more about how online casinos manage their bankrolls, we spoke to Hayden Bowman, Co-founder at iBankroll, a company that provides bankroll services to online casinos. 

Thanks for chatting with Comparasino. Can you start by explaining what is meant by an online casino’s bankroll?

A casino’s bankroll is the pool of money it uses to cover player winnings. In simple terms, it’s the capital available to honour payouts when players win. The larger the bankroll, the higher the betting limits a casino can safely offer to players – within the limits set by the regulator, of course.

How do online casinos ensure they have enough money to pay out players in the event they win?

Traditionally, operators either retain a large cash buffer on their balance sheet or secure credit lines to cover potential payouts. 

What challenges do online casinos face when it comes to bankroll?

The main challenge is volatility from player activity. A small number of high-value players generate most of the action – VIPs can stake six or even seven figures per bet. A single large win can tie up capital or create liquidity stress, particularly for newer operators and new online casino brands. This can limit growth, reduce marketing ROI, and force operators to set lower bet limits than competitors.

Are there any specific requirements put in place by the Gambling Commission?

Yes. UK-licensed operators must demonstrate they can meet player liabilities at all times. They’re required to hold sufficient reserves and to segregate customer funds according to the level of protection promised to players (basic, medium, or high).

Are player funds usually kept separately from the online casino’s bankroll?

In regulated markets like the UK, yes. Player deposits are typically ring-fenced from the operator’s working capital. However, the casino’s bankroll for covering wins is separate – that’s the operator’s own money or credit, not player deposits.

What are the different ways for online casinos to run and manage their bankroll?

There are several options here. They can keep large amounts of cash tied up in reserve or use credit facilities or investors to increase liquidity. They can also join forces with third-party providers (like iBankroll) who assume the risk on bets and provide a predictable, outsourced bankroll.

How does your bankroll-as-a-service work, and what benefits does it provide to online casinos?

Our model removes volatility from the operator entirely. We take on the risk of bets, and the operator instead earns a fixed, predictable share of expected gross gaming revenue. That means operators can raise VIP betting limits without fear of a large win wiping them out.

They can also provide fast withdrawals and high-stakes play becomes possible (we can match any limits offered by the likes of Stake.com) while improving player trust and retention. Finally, operators can free up capital that would otherwise sit idle and can reinvest it into growth (marketing, acquisition, etc).

Do players need to be worried about bankroll at a UK-licensed online casino?

Generally no. UK regulation is strict – operators must prove they can meet liabilities to secure and maintain their licence. That said, players should always check the level of protection a casino offers for customer funds – the higher the better.

Any final thoughts to share with our readers?

Bankroll isn’t something most players think about, but it underpins the entire casino experience. For operators, it’s often the difference between being able to compete with the market leaders or not. New models like bankroll-as-a-service are changing the landscape by giving smaller brands the financial firepower to operate at the same level as industry giants.
