The first is the ongoing cannibalization of in-person gaming by online casinos. The Mid-Atlantic is home to four of the country’s eight legal iGaming states: Delaware, New Jersey, Pennsylvania, and West Virginia.
While in-person casino revenue declined in Delaware, New Jersey, and Pennsylvania, iGaming reported GGR growth in each jurisdiction. iGaming revenue in New Jersey was up 4.4%, Pennsylvania’s online casinos saw GGR climb almost 6%, and Delaware iGaming surged 35%.

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.

“The new hub will display probability data from Polymarket for key economic, government, & market outcomes,” said Polymarket in a post on X last November. “Each probability view will be paired with related news, quotes, & analysis from Yahoo Finance + its partners. By combining trusted data with in-depth analysis, the hub will empower investors to make smarter, more strategic prediction market investments.”
Yahoo—which is 90% owned by private equity giant Apollo Global Management, the firm that acquired operating control of The Venetian in Las Vegas—did not elaborate on why the Polymarket integration ended.
