One of the operator’s most significant challenges is the increase in gambling tax enforced over recent years. Petra has been particularly vocal about this and the company’s profitability has taken a reasonable hit, since the first tax increase to 34.2% of GGR came into effect on 1 January 2025.

Holland Casino now pays 37.8% of GGR to the state, as per the additional increase in 2026, but with labour tax on top the business pays around 52% before they can look at their base running costs. It is not a small burden by any stretch of the imagination, so it is heartening to see the business doing well despite the tightening tax burden.

With such a significant rise in tax, you would forgive the company for cutting wherever possible, but Petra says they have made it work by maximising efficiency, restructuring, and maintaining their offering so the customer doesn’t notice that anything has changed.

The partnership doesn’t end at this stage, as Wazdan is going to further implement new releases for the operator’s local content library and offer players new opportunities as they come back to play. 

Wazdan has been methodically building up its footprint across regional and European markets, with the supplier signing up a content partnership with Jupiter Gaming earlier in September, and similarly bringing its portfolio of player-favorite games to the operator in the UK.

Besides Europe, Wazdan has also been focused on expanding in the North American market. To this end, the supplier teamed up with Caliente.mx, a brand operated by Caliente Interactive in Mexico, bringing the supplier’s games to the local market.

“Here’s an API. Bernard and 88 other people can market-make all these request-for-quotes (RFQs),” Marantelli says. “Some people might come in and just do esports because they’re esports experts. Others do everything. Some focus on same-game parlays. But it’s a sportsbook.”

The institutional layer is largely invisible to customers presented with a P2P proposition. Retail users may technically trade against one another, but the depth required by a mass-market product cannot be supplied by occasional customers alone. Professional firms must be prepared to quote continuously and commit substantial capital.

Marantelli says the London-based White Swan is a significant market maker on several secondary exchanges, accounting for as much as 40% of activity on some platforms. Its particular focus is the RFQ, parlay market.
