About Mistress Of Monsters

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.

Yahoo said Polymarket is still an advertising partner and suggested the two could collaborate on other projects in the future. Polymarket has not provided any public explanation for the end of the data partnership. 

The news comes as prediction market operators continue to form alliances with major media outlets. These deals allow news outlets to embed event contract data into their reporting and offer prediction platforms more visibility to investors and news audiences. 

Polymarket has developed its media presence elsewhere. In January, it signed a deal with Dow Jones to provide its prediction market data to several of the publisher’s consumer platforms. The deal covers publications including The Wall Street Journal, Barron’s, MarketWatch and Investor’s Business Daily.

What is Mistress Of Monsters?

Earlier this year, the Illinois Gaming Board approved 65 VGT licence applications in the city, according to the Sun-Times. VGTs are the highest-grossing gaming vertical in Illinois, generating substantially more revenue and taxes than land-based casinos.

Papanier said the components of Bally’s Chicago that are being “reset and re-contemplated” are “all in conjunction with the proliferation of VGTs”. While the current number of licences is low, he asserted that widespread proliferation could result in a “30% to 50% impact on top-line revenue” for the casino and it would be “irresponsible” to continue construction “until we understand what the landscape looks like”.

Bally’s stock jumped 7% in trading on Monday to $9.84. Shares had fallen 30% in the last month in response to uncertainty in Chicago and warnings about the company’s ability to continue as a growing concern in its Q2 earnings report. Former CFO Mira Mircheva resigned on 4 September, prompting Papanier to take over the role on an interim basis.
