Climate experts are raising alarms as online prediction markets, already saturated with money staked on sport, crypto, and politics, turn their attention to a new area of growth: betting on the weather and the unfolding climate crisis. The concern has been sharpened by a new agreement that allows Kalshi, a leading online financial exchange, to access data from the Weather Company, owner of the Weather Channel, to verify weather-related betting outcomes.
The deal signals a significant expansion of an industry that has increasingly moved beyond traditional financial instruments into event-driven speculation. Platforms such as Kalshi and Polymarket now allow users to place bets on a wide range of outcomes, including whether a given day will break temperature records or whether a heatwave will occur in a specific region. While supporters frame these markets as tools for hedging risk and aggregating public information, critics argue that they are effectively gamifying disasters and profiting from human suffering.
Researchers who study climate communication and public perception warn that treating extreme weather events as betting opportunities could trivialize the real and growing dangers posed by a warming planet. The concern is not merely philosophical. When people stake money on whether a heatwave will strike or whether a particular month will be the hottest on record, the psychological framing shifts from one of shared vulnerability to one of spectator sport. This, experts say, could erode public urgency around climate action and desensitize audiences to the human and economic toll of extreme weather.
The new data agreement between Kalshi and the Weather Company is central to this debate. The Weather Company provides forecasting and data services used by businesses, governments, and media outlets worldwide. By integrating its data into Kalshi's verification process, the exchange gains a reliable mechanism for settling weather-related contracts. That technical step, while seemingly mundane, removes a key operational barrier and makes large-scale weather betting more feasible and credible.
Kalshi has positioned itself as a regulated financial exchange rather than a gambling site. It operates under oversight from the Commodity Futures Trading Commission and argues that its products allow people to hedge against real-world risks, such as a business losing revenue during an unusually warm winter. Polymarket, by contrast, operates on blockchain technology and has faced regulatory scrutiny in multiple jurisdictions. Both platforms have seen explosive growth in recent years, driven largely by political betting and, more recently, by markets tied to crypto assets and sporting events.
The expansion into weather and climate is a logical next step for an industry that thrives on uncertainty and public attention. Heatwaves, cold snaps, droughts, and storms are increasingly frequent and increasingly newsworthy. They also produce clear, measurable outcomes that can be verified quickly, making them attractive candidates for event contracts. But the ethical implications are harder to quantify. Unlike sports or elections, where the stakes are entertainment or governance, weather events affect food supply, infrastructure, public health, and the lives of millions of people.
Some observers have drawn a parallel to the broader debate over climate risk disclosure and financial speculation. Insurance companies have long used climate models to price risk, and futures markets for agricultural commodities have existed for over a century. In that sense, weather-related financial instruments are not new. What is new is the retail-facing, gamified nature of modern prediction platforms, where individual users can place small bets on daily temperature readings with the same ease as they might wager on a football match.
The platforms themselves defend the practice. They argue that prediction markets have a strong track record of forecasting accuracy, often outperforming polls and expert panels. They also contend that allowing people to put money on climate outcomes could increase public engagement with climate science, forcing participants to pay closer attention to data and forecasts. Whether that engagement translates into meaningful action, however, remains an open question.
For now, the trend appears to be accelerating. The Kalshi-Weather Company deal is likely to be followed by similar arrangements as other platforms seek credible data sources to settle weather contracts. Regulators, meanwhile, are only beginning to grapple with the implications of a market where the underlying asset is the state of the planet itself. Climate experts say the industry is moving faster than the rules that govern it, and they are calling for a broader public conversation about where the line between legitimate hedging and harmful speculation should be drawn.
