Yahoo Finance has officially ended its data partnership with the prediction market platform Polymarket. The dedicated hub, which integrated real-time probability data for economic and market outcomes directly into the Yahoo Finance portal, was removed from the platform.
The collaboration began in late January or early February 2026 and lasted for approximately five to six months. The hub was initially taken down in April 2026, with the formal termination of the agreement occurring on September 18, 2026.
While the data integration has ceased, Polymarket remains an advertising partner for Yahoo. Meanwhile, the prediction market sector has become more competitive, as rival platform Kalshi has secured partnerships with major media outlets such as CNN, CNBC, and Fox.
