The investing and news site announced last week that it halted an arrangement in which it used Polymarket prediction market data for a dedicated hub on the website.
That relationship ended in April, just six months after it started. Yahoo Finance confirmed the end of that agreement to Bloomberg but noted that Polymarket remains an advertising partner.
“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.

In July last year, Veikkaus iGaming EVP Jarkko Nordlund told iGB: “The competition will be fierce when the market opens, so we must be very competitive. Our aim is to challenge the mentality of our current position, so we need to secure market leadership.”
