What is Roman Rule?

Prediction market operators are on legal losing streaks, confirming that Beynon is onto something when he says the regulatory environment is the biggest risk facing the industry.

“We continue to view regulation as the largest risk to prediction markets,” says the analyst. “While industry growth remains robust, adverse legal outcomes could materially impact sports contract availability and long-term adoption.”

Amid a string of losses in federal appellate courts, it appears increasingly prediction markets are angling to take their cases to the U.S. Supreme Court, banking that the high court will allow them to continue offering sports event contracts free of state gambling regulations.

Is the monopoly safe, is it set in the law that it will operate forevermore? No, it’s under constant evaluation, Petra explains: “The Dutch state, represented by the Ministry of Finance, is our shareholder and they evaluate every seven years, not only us as Holland Casino, but all state-owned companies.”

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.
