Yahoo Finance has ended the partnership it announced last November, under which it used Polymarket’s pricing data to run a prediction-market hub on its website. Bloomberg’s Hannah Miller reported on 18 September that the hub — built to display probability data for “key economic, government, & market outcomes” — was taken down in April, and that the agreement as a whole has now concluded.
Neither party gave a reason. What Yahoo gave instead was a statement that separates two things the original announcement had bundled together: “We had a previous partnership with Polymarket to display relevant prediction market data across Yahoo Finance. That specific agreement ended, but Polymarket continues to be an advertising partner across Yahoo and we’re open to similar types of partnerships.” Polymarket declined to comment.
One layer came off, the other stayed
The reader-facing layer is gone. The customer-acquisition layer is not, and it is the one that moves money toward the product. Yahoo’s own description of the surviving arrangement is the plainest available statement of what a news organization gets out of this: a partner that buys inventory, plus the option of another data deal later.
That matters because the two channels are substitutes for the same job. A prediction market buys distribution by paying for it — celebrity endorsements, brand campaigns, sports sponsorships — and by getting its numbers treated as information, which is cheaper and more durable. A probability displayed on a financial news site next to a jobs report or a Fed decision is not advertising. It is the product’s vocabulary installed in the layout of reporting, and Bloomberg’s own description of what those numbers are is worth keeping in view: “the odds on the platform reflect the balance of trading on the platform.”
The partnerships are the strategy
Yahoo was one of several outlets to cut deals of this kind, and the map is now large enough to be a distribution network:
- Polymarket agreed in January to feed prediction data to News Corp’s Dow Jones, the parent of the Wall Street Journal and other publications.
- Kalshi has announced partnerships with Warner Bros. Discovery’s CNN, Versant Media Group’s CNBC and Fox Corp.
- Bloomberg LP — the parent of Bloomberg News — holds no such partnership, but supplies Polymarket and Kalshi data to clients as part of its broader data offering.
- On the entertainment side, Polymarket paid for an exclusive Golden Globes partnership that put category win probabilities on screen during the 2026 ceremony broadcast, and LeBron James signed an endorsement deal worth $15m a year, per Front Office Sports.
Both companies argue this can enhance journalism. The CJR Tow Center has questioned whether the prices accurately capture public sentiment, and cash-strapped news organizations have been criticized for treating the deals as a revenue line. Both criticisms describe the same transaction from different ends: a newsroom short of money sells a data label to a company that needs the credibility of a newsroom more than the newsroom needs the odds.
The unsettled half
The platforms’ legal position is that they are derivatives exchanges supervised by the CFTC, not gambling operators. State regulators are litigating that claim in court, and prosecutors have pointed to alleged insider-trading cases on the platforms — a category of conduct that reads differently when the same prices are printed beside financial news as a forecast rather than quoted as a wager.
The agreement’s quiet end is not evidence that any of this was resolved. Yahoo’s door is explicitly still open. What ended was one display arrangement; what remains between the two companies is a paid placement, which was always the part that reached the reader who never went looking for a betting product. The cost of that arrangement is not charged to Yahoo or to Polymarket. It is charged to the reader who mistakes a market’s self-reported price for a fact about the world, and to the states whose gaming laws the product is, on the platforms’ own account, not covered by.
