Payment Apps Block 1 in 3 Casino Deposits Under New Rules

Poland's largest payment intermediaries are now declining roughly one in three attempted deposits to licensed online casinos, according to data compiled from six operators and two payment processors for the first quarter of 2026. The block rate — 33.4% across 1.19 million deposit attempts — marks a sharp jump from 8.1% in the same period last year, and it is the clearest sign yet that the compliance layer sitting between Polish players and licensed operators has become a filter rather than a pipe.

The number matters because it is not a technical glitch. It is the visible output of new transaction-screening obligations that took effect on 1 February 2026, layered on top of the existing block on unlicensed gambling merchants maintained under the 2017 amendment to the Gambling Act.

What actually changed on 1 February

The rules themselves are not new in kind — Polish banks and payment institutions have been required to refuse card and transfer transactions to unlicensed operators since 2018, and the Ministry of Finance maintains a public register of blocked domains and accounts. What changed is the scope of screening.

Under the amended framework, payment service providers must now assess gambling transactions against a wider set of risk flags before authorisation, not after. In practice, that means a deposit can be declined for reasons that have nothing to do with whether the operator holds a Polish licence: mismatch between the account holder and the gambling account, velocity checks on repeat deposits within a 24-hour window, and — most contentiously — a category of "insufficient merchant verification" applied when the acquirer's data does not fully match the merchant record held by the intermediary.

Operators say that last category is doing most of the damage. One compliance officer at a licensed Polish-facing casino, who asked not to be named because the figures are commercially sensitive, put the misclassification rate among declined transactions at "somewhere around 40% of the declines we can actually trace." If that holds across the market, roughly 13% of all deposit attempts are being blocked for reasons unrelated to licensing status.

The Ministry of Finance has not published its own decline statistics. In response to questions, a spokesperson said the ministry "monitors the effectiveness of the blocking mechanism" but declined to give figures, citing ongoing supervisory work.

The card problem, and why BLIK is different

The block rate is not evenly distributed across payment methods, and the split explains much of the friction.

Card deposits — Visa and Mastercard, processed through international schemes — show the highest decline rate in the sample, at 41.2%. That reflects both the additional screening layer and the fact that card transactions carry more identifiable data points for an intermediary to flag against.

BLIK, the domestic scheme operated by Polski Standard Płatności, is lower but rising. Decline rates there sat at 19.7% in Q1 2026, up from 4.3% a year earlier. BLIK transactions are initiated inside a banking app, which gives the payer's bank first sight of the merchant and, in theory, a cleaner basis for a decision. The catch is that the decision now rests with the bank rather than the scheme, and banks have been applying their own risk appetites inconsistently.

Among the six operators surveyed, one reported a BLIK decline rate above 30%; another reported under 9%. Neither would go on record with the figures. That spread — more than threefold between operators selling to the same market under the same licence — suggests the outcome depends less on the rules than on which bank a player happens to use.

What players are doing instead

Blocked deposits do not disappear. They move.

Customer support logs from the surveyed operators show a consistent pattern after a decline: within 30 minutes, a meaningful share of players attempt a second deposit through a different method, and a smaller share abandon the licensed operator altogether. The second-attempt success rate is high — above 70% in the data we reviewed — which means many declines are resolved by simply trying again or switching rails.

The concerning group is the third one. Operators estimate that between 6% and 11% of players who hit a hard decline — one they cannot resolve by retrying — migrate to unlicensed sites within the same session. That is an estimate, not a measurement, and it should be treated as such. But it points at the central tension in the current framework: a control designed to keep money out of the black market may be pushing some of it there.

Polish trade body Graj Legalnie has raised this in correspondence with the ministry, arguing that the screening thresholds are producing false positives at a rate that undermines the licensed sector without measurably reducing unlicensed play. The ministry has not responded publicly to that argument.

The operator economics

For licensed operators, the arithmetic is uncomfortable but not existential — yet.

A 33% decline rate on deposits does not translate directly into a 33% revenue loss, because a large share of blocked transactions are retried successfully. Operators in our sample estimated the net revenue impact at between 9% and 14% for Q1 2026, against a counterfactual with no incremental screening. On a market where licensed online gambling generated roughly PLN 6.8 billion in 2025, that is a meaningful number.

The costs are also operational. Each declined transaction generates a support ticket, a compliance review, and in some cases a manual override request. One operator reported that deposit-related support contacts rose 58% quarter-on-quarter. Compliance headcount at the same operator is up by four full-time roles since January.

Smaller operators feel this more than the large ones. The fixed cost of building and maintaining screening infrastructure does not scale down, and a mid-sized casino with a few thousand active players carries the same compliance overhead per transaction as a market leader. Two of the six operators we contacted said they had paused affiliate spending in Poland for Q2 while they assess whether the decline rates are structural or transitional.

What happens next

The framework is due for its first formal review in September 2026, when the ministry is expected to publish aggregate data on blocking effectiveness for the first time. Until then, the market is operating on estimates, operator surveys, and the occasional leaked figure — an uncomfortable position for a sector that argues, with some justification, that it needs stable and predictable rules to compete against offshore sites that ignore all of them.

The open question is not whether the screening should exist. It is whether a mechanism that declines one in three legitimate deposits, and that produces a threefold variation in outcomes depending on which bank a player uses, is doing the job it was designed to do — or whether it is simply teaching Polish players which payment methods to avoid, and which sites to visit when the licensed ones say no.
