Polymarket and Kalshi Expand Into Media as Prediction-Market Regulation Fight Looms
Polymarket runs a daily newsletter summarizing news events tied to its betting markets, resembling a political news roundup rather than a financial disclosure. Both Polymarket and rival Kalshi have struck data-sharing partnerships with major media companies—Polymarket with Dow Jones and Substack, Kalshi with CNN, CNBC, and Fox—embedding themselves into roughly a quarter of top S&P 500 communications firms, though none of these deals involve actual trading.
