The Great Wall

How to play The Great Wall

“Premier League clubs that have struck new deals with unlicensed gambling operators knew the risks,” she said. “The government made clear in February that it would bring in a ban and it should do so immediately: even if that means clubs ordering new kit mid-season.

“Inconvenience is not an excuse for inaction.”

According to Entain, the consultation included data that demonstrated 22% of consumers who use unlicensed operators first interacted with them through social media, with 13% via sponsorship.

What is The Great Wall?

The two companies began collaborating in November 2025. As part of the deal, Polymarket provided data for a dedicated prediction market section on Yahoo Finance. The feature provided market-based probabilities of economic, political, and financial developments alongside Yahoo Finance content. 

The Yahoo Finance prediction market section was taken out in April. The companies have now confirmed that the larger deal is also off, as reported by Bloomberg. 

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. 

About The Great Wall

The US land-based casino market had begun to mature and the number of obvious new markets and projects was shrinking. Online gambling offered a new source of growth, particularly through the expansion of legal sports betting. That opportunity was quickly reflected in share prices.

The problem is that legalisation has not happened as quickly as expected, while taxes and competition have increased. “Online gaming has been affected by the broader re-rating of growth-oriented internet and software stocks,” says Chad Beynon, managing director and head of US research at Macquarie Capital. “But there has also been a genuine deterioration in expectations for parts of the sector.”

Beynon says sports betting companies have suffered particularly badly because the market is questioning both future earnings and the size of the eventual opportunity. More iGaming-focused companies such as Rush Street Interactive and Super Group have generally performed better operationally, helped by stronger earnings growth and profitability.
