Holland Casino calls this Next Zone, and as Petra elaborates: “It’s an innovation we made a few years ago to see how we can develop a casino product because I think in the industry, we are very well known for what we have, but how do you innovate?”

Like most operators, slots make up the bulk of Holland Casino’s income, but it’s worth remembering that Holland Casino has a monopoly on table games, poker and bingo. “I would say those are also our hero products that make us attractive because in the Netherlands we are the only one offering land based live table games,” says Petra.

“Maybe they’re not so dominant in the results, but it is dominant in our identity. But figures-wise, slots are bigger than table games.”

Even before the primetime matchup in Kansas City, it became abundantly clear that the industry would shatter previous marks for weekly activity. The AFC West showdown bolstered the already robust totals. Overall, volume for the week hit a record $15.9 billion, according to Bank of America, up 16% from a week earlier.

The pure-play prediction market-operators, Polymarket and Kalshi, emerged from Week 1 as the clear winners. On one hand, Kalshi’s market share lead narrowed over its competitors, falling to 82% for the week ended 13 September, down from 86% a week earlier.

Still, Kalshi had a nine-fold lead over Polymarket, its next closest rival. Polymarket, meanwhile, led the group with 762,000 app downloads, edging Kalshi, DraftKings and FanDuel in the category. The downloads represented a 13,509% weekly increase and 25% of total category downloads, Polymarket wrote in a statement.
