Overview
- Kalshi and The Weather Company announced the partnership on Thursday to use Weather Company data to verify outcomes for some weather contracts and to display Kalshi market probabilities on Weather Channel platforms.
- The deal replaces previous settlement sources for some markets with Weather Company observations and forecasts so that contract outcomes rely on a single, authoritative meteorological dataset.
- Commercial demand is growing for weather contracts as hedges: a Houston brokered block trade posted to Kalshi in August tied a $25,000 payout to William P. Hobby Airport reaching 103°F as a prenegotiated risk transfer.
- Kalshi reports its climate and weather vertical grew about 500% year over year and is on pace for roughly $1.1 billion in annualized trading volume, showing rising business use beyond hobby bets.
- The company still faces legal and ethical headwinds because states have sued over whether prediction markets are gambling and critics worry markets on disasters could create perverse incentives, a tension that the Weather Company tie aims to address.
