About Mystery Mice
The conclusion of the Yahoo Finance deal comes as there is more talk about the use of prediction market data in journalism. Operators such as Polymarket and rival Kalshi have touted their markets as a way to get real-time information on how likely future events are to occur.
However, some media industry observers have questioned whether trading activity can reliably stand in for broader public opinion. There are also concerns among critics over the growing links between news organizations and prediction platforms.
At the same time, prediction market operators are facing regulatory tussles in the US. State regulators are moving to shut down the firms under gambling laws. The companies say their contracts should be regulated at the federal level as derivatives.

How to play Mystery Mice
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.
