The number above a casino game keeps climbing. It looks like a prize waiting to happen, but behind the display sits a less visible question: whose balance sheet must absorb the win? The answer depends on the jackpot arrangement. Rush Street Interactive says it contributes part of each qualifying online-casino wager to its progressive pools and carries the resulting jackpot obligation in its own accounts. Super Group describes a different, third-party network model: it owes contributions to the pool, while the jackpot win is a liability of the outside jackpot operator. Neither filing tells us who would pay a prize on every casino site. Together, they show why the logo on the lobby tile is not enough to identify the party bearing the payout risk.

This is an operating story, not a strategy for chasing a large number. A progressive jackpot grows under defined rules, and the display does not predict when it will be won. The more useful thing to read is the chain connecting a stake, a pool, a trigger and the eventual obligation to pay.
The meter is not the money
A progressive prize can start from a seed amount and rise as eligible play contributes to it. The visible meter is the player-facing expression of that system; it is not, by itself, evidence that the displayed amount sits in a dedicated bank account. Great Britain's Gambling Commission says the rules for a progressive jackpot should explain its funding, starting seed and any ceiling before a player commits to gamble. Its guidance also calls for clarity about what happens to contributions after a cap is reached. Gambling Commission RTS 9
One casino might fund and owe the prize itself. Another might feed a supplier-operated network connecting games or sites. The same animation—numbers ticking upward—can sit on top of different commercial contracts and accounting entries. Our guide to the casino-game supply chain separates the studio, game server, distributor and consumer operator; a jackpot adds a pool and a party responsible for it to that chain.
The percentage of a stake feeding a pool is not automatically the same as a game's return to player. RTP describes the long-run mathematical return of the game under its stated assumptions; a jackpot component may be shown with the base game or separately. The British guidance explicitly permits either presentation, while requiring ineligible players to be told that they cannot win the progressive prize and what theoretical RTP applies to them. Our RTP explainer deals with what those percentages can and cannot say about one session. RTS 9 jackpot guidance
Two filings, two places for the obligation
Rush Street Interactive provides a clear operator-side example. In its filing for 2025, the company says each play of its progressive-jackpot games contributes a portion of the amount bet to the relevant game or group of games. When a jackpot is won, it pays out and resets to a predetermined base. Rush Street says jackpot payouts can reduce its cash position; it also records the progressive jackpot liability within a broader Players' liabilities line on its balance sheet. That line contains other obligations too, including customer account balances and unredeemed incentives. It must not be mistaken for a separately disclosed pile of cash equal to the jackpot meter.

Super Group's annual filing describes a different slice of the industry. For certain third-party progressive-jackpot network games, it records an obligation to contribute an amount from associated wagers to an outside pool. The filing says winnings in those arrangements are a financial liability of the third-party jackpot operator. Super Group treats its pool contributions differently from ordinary royalties paid to a game supplier. This is the company's stated accounting model for those arrangements—not a claim that every game on Betway, Spin or any other brand follows it. Super Group 2025 Form 20-F, revenue-recognition note
The comparison has a sharp limit: Rush Street's disclosure concerns its own operations; Super Group's describes third-party network games in a multinational group. They are not two offers for the same jackpot, and these filings do not establish a universal rule about who a customer should sue, contact or expect to see named on a payout screen. The player-facing operator, the pool administrator and the contractual bearer of a prize can be different entities. To find the answer for a particular game, the game rules and the relevant operator's terms matter more than a company-wide generalisation.
A network has to remember who got there first
Funding is only half the design. A linked progressive can receive eligible stakes from more than one game or site, so the system must track contributions and decide precisely when a win was triggered. The British Commission's RTS 9 guidance says rules should cover prizes that two players trigger—or appear to trigger—at the same time because of network latency. It also calls for the winning player to be notified immediately after a trigger and for other participants to see the reset value. RTS 9, award and reset provisions
The technical problem is more than refreshing a big display. Gaming Laboratories International's 2026 *GLI-12* standard describes a jackpot controller that processes contributions, records trigger order and handles communication loss or inconsistent configuration. A linked meter can become unavailable when its controller cannot operate reliably. GLI-12 is a testing standard, not a statement that every jurisdiction adopts every clause. It shows the kind of machinery and event record that a multi-participant promise requires. GLI-12, version 3.0
That is why a screenshot of a rising amount cannot settle a dispute about a particular spin. The relevant evidence is the accepted game round, its eligibility, the controller's recorded trigger and the game rules in force at that moment. Our article on live-casino disconnections covers a different interruption problem: whether a stake and result survived a break in the game session. A jackpot fault adds a shared pool and competing claimants to the record.
Closing the game does not make contributions vanish
The end of a jackpot is not necessarily the moment someone wins it. A game can be withdrawn, a network can change or a capped pool can stop growing. In Great Britain, the Commission's implementation guidance says player contributions in a decommissioned jackpot should be returned fairly according to the circumstances, with priority for the players who made them. It gives three possible approaches: wait for the next award, move remaining contributions to another appropriate jackpot, or return them directly with an explanation. It does not say every closure produces an immediate cash refund for every contributor. RTS 9, decommissioning guidance
This is where contracts and product records meet. The operator needs to know which game version was offered, who contributed, who administered the pool and which rule governs a move or closure. Our report on different versions of the same casino game explains why a familiar title does not identify a tested build. A jackpot can add another versioned component whose funding and eligibility rules need to travel with it.
The useful question behind a large number
For a reader, a jackpot meter tells only part of the story. The game rules should say who can enter, how the prize is funded, whether it has a seed or ceiling, how a tie is handled and what happens when the system resets or ends. None of those answers makes a win more likely on the next round. They make the offer intelligible. Gambling Commission RTS 9
For the business, the distinction is financial as well as technical. Rush Street describes a jackpot exposure it accrues and pays. Super Group describes third-party network arrangements in which it funds a pool but the outside operator bears the jackpot-win liability. Both can put an attractive counter in a casino lobby. The difference sits in the obligations behind it—and in whether the rules, controller records and accounting all describe the same promise.
