Kalshi and Polymarket partner with CNN, CBS News, CNBC and Dow Jones ahead of the U.S. midterms, with election volume near $1.5B

Kalshi and Polymarket have secured commercial partnerships with CNN, CBS News, CNBC and Dow Jones ahead of the November 3 U.S. midterm elections, according to Bloomberg reporting relayed by BlockBeats on October 30 and published by KuCoin. The arrangements bring election-market odds into media coverage, though their use will vary by outlet.

Election-related trading across the two platforms totaled approximately $1.5 billion, according to Bloomberg’s analysis of Dune data. That figure measures trading volume, rather than the accuracy of the probabilities those markets produce.

Different outlets, different arrangements

CBS News named Kalshi its prediction market sponsor. CNBC disclosed a Kalshi collaboration that includes revenue sharing tied to customer acquisition and a minority equity stake, according to the report.

The Wall Street Journal, part of Dow Jones, displays a column of Polymarket odds on its homepage. The reported partnerships therefore span sponsorship, commercial incentives and the presentation of market probabilities alongside news.

Limits on election-night coverage

The agreements do not mean prediction-market odds will appear across all election programming. Fox and CNN said they would not report odds during their election-night broadcasts, according to Bloomberg.

CNN’s inclusion among the commercial partners, alongside its stated election-night restriction, highlights a distinction between a media partnership and how an outlet chooses to cover results. The supplied report does not detail CNN’s commercial terms.

What it means for prediction markets

• More distribution: The partnerships give Kalshi and Polymarket additional exposure through established news outlets, but the report does not quantify any resulting increase in users or trading.
• Commercial terms matter: CNBC’s customer-acquisition revenue sharing and minority equity stake make its arrangement distinct from CBS News’s sponsorship.
• Volume is not validation: Approximately $1.5 billion in election-related trading indicates activity across the two platforms; it does not establish forecasting accuracy.
• Broadcast exposure has limits: Fox and CNN’s election-night decisions mean readers should not assume commercial partnerships translate into on-air odds coverage.
