Kalshi partners with The Weather Company on climate event contracts
Kalshi has partnered with The Weather Company to offer climate-related event contracts on its CFTC-regulated exchange. The Weather Channel owner will supply weather data and forecasting for the markets. Kalshi says small businesses use the contracts to hedge weather-related losses, not merely to wager. The deal comes as event-contract classification faces ongoing legal challenges. No financial terms or specific product launch dates were disclosed.
Weather contracts are Kalshi's volume lead, and this data partnership locks in settlement integrity just as Polymarket's Sportradar sports expansion threatens Kalshi's position elsewhere. Exclusive forecasting from The Weather Company blocks competitors from disputing contract resolutions, a defense Kalshi lacks in sports or politics. Small-business hedging demand gives the vertical a revenue story beyond retail wagering, broadening the user base.
The risk is concentration: deep investment in climate leaves other categories exposed while Polymarket piles on leagues and streaming. Kalshi's earlier weather deal with The Weather Company combined data licensing with app distribution, suggesting this is a layered defense of one vertical rather than portfolio diversification. Kalshi needs weather volume to hit its targets or the revenue mix skews dangerously narrow against a rival with broader event coverage.
