Kalshi and The Weather Company announced a settlement-and-distribution pact on Thursday that changes how climate contracts are closed and how forecast readers view live prices. Kalshi will resolve weather-related event contracts using The Weather Company’s enterprise observation feeds. The Weather Channel app and weather.com will show Kalshi climate market probability data in selected products. The firms are also exploring contracts tied to ski conditions and marathon race days.
Kalshi states its climate and weather vertical has grown 500% year over year and is pacing toward $1.1 billion in annualized volume. That run-rate includes $564 million through July, already more than last year’s full-year weather total. Daily high-temperature contracts that once settled on National Weather Service prints moved to Weather Company data on August 14. As we’ve noted on PolyPunter, the platforms are placing a heavy emphasis on resolution sources and rules, continuously trying to improve the perceived integrity of their settlement processes.
The deal is aimed at businesses, freight desks, and risk firms that treat heat and rain as cash exposures. An ice cream operator facing a cool stretch and a logistics team tracking storms can now point to the same settlement source that powers consumer forecast apps. The Weather Channel has been live since 1982.
How Weather Company Data Will Settle Climate Contracts
Kalshi’s official announcement says The Weather Company will supply the observations used to close temperature, precipitation, and related contracts. Dr. James Belanger, vice president of meteorology at The Weather Company, said settlements must rest on “objective, scientifically validated atmospheric data,” with each print carrying a documented method reviewed by the firm’s meteorologists.
Will Brackett, Kalshi’s head of partnerships, called weather one of the exchange’s fastest-growing categories because it touches households, companies, and public agencies. He said market prices give people another way to gauge uncertainty alongside a traditional forecast. The split of duties stays simple: The Weather Company provides settlement data and consumer placement; Kalshi writes the contracts, runs the exchange, and resolves markets under its CFTC designation.
Weather outcomes are hard to move with leaked briefings, because no trading desk controls tomorrow’s high. (Though there have been reports of individuals trying to manipulate weather stations or gauges to falsify readings, these are largely anecdotal and likely curable, though something to keep in mind as a potential.) The inability to have insider information on weather matters, after months of scrutiny of event contracts that can reprice based on private information. Contract pages already list weather.com/kalshi as the public window for official prints.
A SmithGeiger Media Trends Omnibus cited in Kalshi’s release found that 89% of U.S. adults say weather shapes how they plan their day. That overlap is the commercial hook. Forecast apps already own habitual traffic. Adding implied probabilities turns a familiar screen into a price feed that now becomes a tradeable futures contract.
Hedges, Block Trades, and the Climb Past Last Year’s Weather Book
Traders are pricing in daily highs, monthly rain totals, and longer-term climate questions, such as whether 2026 will finish as the hottest year on record. Companies are already using the contracts as weather hedges rather than novelty tickets.
The Houston Chronicle reported that risk-management startup Discrete completed what it described as Kalshi’s first privately negotiated weather block trade. The contract pays $25,000 if a designated station hits 103°F in August. Founder Harp Singh said traditional insurance can take weeks to place, while the Kalshi ticket came together in days. If the threshold hits, the payout offsets heat-driven costs. If it misses, the hedge expires.
Kalshi’s weather hub lists daily highs, rain, and climate signals as live series. Market-data tools have already rebuilt feeds in response to the August API change and the settlement switch. Kalshi has also been selling the idea directly to consumers.
Kalshi Prices Move Into The Weather Channel App
The second half of the pact is distribution. The Weather Company will display Kalshi’s real-time probabilities in select experiences on The Weather Channel app and weather.com. Viewers will start seeing those odds beside familiar forecast modules, so a high-temperature outlook can sit next to the market’s implied chance of that high. This is similar to how sports prediction market probabilities are now being shown alongside sports scores and stats on other media outlets. Or how outlets like CNN are doing the same when reporting geopolitical news for those affected by prediction platform markets.
Weather Company stories that use the data may disclose that the firm supplies settlement inputs, that Kalshi supplies the market figures in the article, and that referral links can generate a fee if a reader opens an account. That disclosure matters because the same company that helps resolve contracts will also display the prices those contracts yield.
For traders, the integration shortens the gap between a forecast revision and a price. A morning update that lifts a heat outlook can move a daily high contract in real time, while the reader is still on the forecast page. For The Weather Company, the feed is another content layer, not a substitute for meteorology, but an additional interest point for their audience.
Thursday’s announcement hardens the settlement rail under a fast-growing weather book and parks live Kalshi prices within one of the most-watched forecast brands in the country.
