The New York Times union sent a letter demanding the company abandon talks with Kalshi over a potential partnership with The Athletic, the Times' sports media unit. The union warned that any deal would threaten journalistic independence across the company. The letter does not specify the exact nature of the proposed partnership or its current stage.

A collapsed or blocked deal would deny Kalshi a major sports-media distribution channel and signals that newsroom unions may resist prediction-market partnerships on editorial-integrity grounds.
