About Bison Valley

“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.

Yahoo Finance is one of the most visited financial news websites in the world, implying it’s a blow to Polymarket that its prediction market hub was pulled, but the operator has other prominent financial media deals.

Kendrick sees a warning in the history of betting exchanges. In their early growth phase, there was sufficient retail liquidity for numerous market makers to profit. As that retail pool weakened, the sharper firms increasingly found themselves trading against one another.

In March, Polymarket opened The Situation Room, a pop-up “newsbar” in Washington, DC. The bar and lounge’s televisions played various content related to prediction markets, like Bloomberg Terminals, cable news, and live social media feeds that were “dedicated to monitoring the situation.”

A month earlier, Polymarket opened a free grocery store in New York City. The promotion ran Feb. 12-16, with shoppers allowed to gather up to $50 per person in free groceries.   

More recently, Polymarket has paid top dollar for prominent athletes and celebrities to promote its prediction market. The company’s paid partners include LeBron James, Derek Jeter, Eli Manning, Spike Lee, and Craig Robinson.
