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.

We mentioned that southern border because German players apparently enjoy the Holland Casino offering too. “German visitors are really interested because we have a different offer from most of the German casinos,” Petra explains.
“If you look at our land-based casinos, it’s table games, slots, in some cases bingo, and on some evenings, poker. But there are also restaurants, entertainment. It’s an afternoon or evening out. And as I understand from our German guests, it’s a more entertaining evening or afternoon than in some German casinos.”
