The Mid-Atlantic struggles weren’t limited to New Jersey, as Pennsylvania revealed today (Sept. 17) that brick-and-mortar gross gaming revenue (GGR) from slot machines and table games totaled $280.3 million.
Pennsylvania casino revenue for August was almost 6% lower than a year ago, when the state’s casinos won $297.7 million from their physical slots and table games. Pennsylvania’s August 2026 struggles came despite the state having one more casino last month than it did in August 2025, as Happy Valley Casino only opened in April 2026.
In Maryland, the state’s six casinos combined to win $160 million in August, representing a 6% drop from the prior year. In Virginia, casino revenue from its five casinos was $97.6 million, almost 5% lower than August 2025.

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.
However, the sector has grown substantially despite such disputes. Bernstein predicted in April that annual prediction market volume could reach $1 trillion by 2030. The research estimated volume was around $51 billion in 2025 and could grow to around $240 billion in 2026.
The partnership with Yahoo Finance wraps up as prediction markets push for broader distribution across financial media, sports, and entertainment platforms. For Polymarket, the loss of the Yahoo Finance hub is one distribution channel, but other partnerships remain intact.

The investment banking and capital markets firm Jefferies said in a September report that sports had become prediction markets’ “most important liquidity driver”, with combo and parlay-style contracts accounting for an increasing share of activity. But the analysts cautioned that prediction markets are scale businesses with relatively low revenue yields, leaving their economics dependent on sustained liquidity, engagement and trading activity.
James Monk, founder of sports data and streaming provider Catalist Sports, has witnessed that dependence directly. Catalist supplies ITF tennis data to Kalshi and Polymarket and has an exclusive US sports-streaming agreement with Kalshi.
The company must also provide data to the firms making markets on those events.
