Yahoo Finance formally concluded its data partnership with blockchain-based prediction market Polymarket on September 18, 2026, after removing the dedicated prediction-markets hub from its platform in April. The companies began collaborating in November 2025, when Polymarket was named Yahoo Finance's exclusive prediction-market partner. The hub, which launched around late January or early February 2026, displayed Polymarket's real-time probabilities for events including Federal Reserve rate decisions and economic indicators. Neither company disclosed why the data integration ended. Polymarket will continue advertising across Yahoo's broader properties, while Kalshi, a US-regulated prediction-market platform, has partnerships with CNN, CNBC and Fox.
