What these markets are, how a temperature or storm contract actually settles, the official data sources that decide them, and the questions worth asking before you trade. We explain the mechanics, we never call the weather.
Weather and climate prediction markets are binary contracts on a defined weather outcome, for example whether a city's high temperature reaches a set level on a given day, or whether a named storm makes landfall in a window. Each contract pays one dollar if its outcome happens and nothing if it does not, and the price reads as an implied probability. They settle against official data such as the National Weather Service. This is general information, not advice.
Weather and climate prediction markets let people trade contracts on a clearly defined weather outcome, most often a temperature question such as whether a named city's daily high reaches a stated level, or a storm question such as whether a hurricane of a given category makes landfall in a window. Each contract is binary, settling at one dollar if the stated outcome occurs and at zero if it does not, so a price of forty cents implies the market is pricing roughly a forty percent chance. What sets this category apart is its objectivity. The outcome is decided by a published official measurement rather than a judgment call, which removes a lot of ambiguity but does not remove the risk of being wrong.
The weather category covers more than a single bet on whether it will be hot. The most common shape is a temperature threshold contract, asking whether a named station's daily high or low is above or below a stated level, often offered as a set of multi bracket markets so you can trade a specific range rather than a single line. Around those sit accumulation contracts on monthly rainfall and snowfall totals for major cities, and storm contracts that ask whether a named storm, or a storm of a specific category, makes landfall in the United States within a defined window. Because a full Atlantic hurricane season runs from June through November, storm markets appear as both seasonal questions and shorter rolling contracts as systems develop.
The underlying idea is the same across all of them. You are buying a claim on a defined future fact, and the price you pay is the market's current estimate of how likely that fact is. In an exchange model there is no house taking the other side, only other traders, and the venue earns from fees or the spread rather than from your losses. Because these questions are precise and time bound, naming the exact station, the exact threshold, and the exact window, the wording of the contract matters as much as your read of the forecast.
A weather market is only as reliable as the official source that decides it, so this is the single most important thing to check. On regulated United States venues, daily temperature markets commonly resolve against the figure reported by the National Weather Service for a specific named station, with the final climate report typically published the following morning. Either the official reading reached the threshold or it did not, and that objectivity is what makes settlement clean. The source is not interchangeable, though. A contract tied to one airport station can settle differently from one tied to a nearby station on the same day, because the official measurement differs by location.
Storm and precipitation contracts work the same way, naming the authoritative source and the exact condition that resolves them, such as a specific agency's classification of a landfall or a published seasonal total. Before you trade you should read the exact source, the exact measurement, the exact time window, and how the contract handles edge cases such as a delayed report, a revised figure, or a borderline reading. Two contracts that look identical can settle differently because of one line in the rules, so the rules page is where the real work is.
Costs vary by venue and structure, so compare like with like rather than assuming the headline price is the full cost. The figures below are indicative and dated, not quotes, and you should confirm current terms on each platform.
| Venue type | Cost model | Funding | Notes |
|---|---|---|---|
| Regulated US exchange | Per contract fee, often scaled to price | Linked bank, card, or wire in US dollars | Settles against official data such as the National Weather Service |
| Onchain market | Spread based, low explicit fees, plus network fee | Stablecoin such as USD Coin on a given network | Self custody; standing is contested for United States users |
| Order book venue | Maker and taker fees vary by venue | Varies by platform | Spread and depth are real costs in thin or short dated markets |

Weather markets carry the general risks of any prediction market plus a few of their own. The first is forecast uncertainty. A short dated temperature or storm contract can move sharply as new model runs and observations arrive, so a position can lose value fast even when your broader read looks sound, and a confident crowd can still be wrong when the atmosphere does something unusual. The second is resolution detail. A market hinges on one named station, one threshold, and one window, so a reading that lands a degree away, or a report that is delayed or revised, can decide an outcome in a way that surprises a trader who skipped the rules. The third is liquidity. Many weather contracts are short dated and niche, so books can be thin, spreads wide, and exiting at a fair price is not guaranteed. None of these makes the category unusable, but each is a reason to size positions carefully and to treat any price as an estimate carrying a real risk of loss.
Weather and climate markets appear on more than one kind of venue, and which are open to you depends on where you live. Federally overseen United States exchanges offer temperature, precipitation, and storm contracts to verified users under Commodity Futures Trading Commission oversight, while onchain platforms run without United States registration and are a contested question for United States readers, and availability shifts as rules change. We link you to a platform only where it is genuinely available to you, so the right next step is to compare the venues open in your place and read your local legality page before funding anything.
Weather markets trade in several places with very different rules and costs. Compare the platforms genuinely available where you live, and read your local legality page before you put money in.

In the United States, event contracts on weather and climate outcomes that are listed on a registered venue fall under the oversight of the Commodity Futures Trading Commission, while onchain venues without United States registration sit outside that framework and raise a separate, contested question for United States users. The underlying measurements come from official sources such as the National Weather Service, and each market should name its own source, station, and method on the rules page. For this guide we drew on the platforms' own published market rules and help materials and reputable reporting current to June 2026, and we mark contested points as contested rather than presenting a settled answer where there is not one. Confirm the live position with the platform and with the relevant regulator before you act, and never assume a figure or a source we have not verified.
Weather prediction markets can lose you money, because forecasts are uncertain and short dated contracts move quickly. Trade only what you can afford to lose, never to chase a loss, and never with borrowed money. A confident price is not a safe one, and a market can be wrong.

A weather prediction market is a market in binary contracts on a defined weather or climate outcome, such as whether a named city's high temperature reaches a stated level on a given day. Each contract settles at one dollar if the outcome happens and zero if it does not, and the price between one cent and ninety nine cents reads as the implied probability. This is general information, not advice.
It settles against the official data source named in the contract rules. On regulated United States venues, daily temperature markets commonly resolve against the final figure reported by the National Weather Service for the named station, typically published the following day. Always read the named source, station, and time before trading.
On federally overseen United States exchanges, weather and climate event contracts are offered to verified users under Commodity Futures Trading Commission oversight, as of June 2026. Onchain venues without United States registration are a separate, contested question for United States users. Check your local legality page and the platform terms before trading.
Common shapes include daily high and low temperature thresholds and ranges for major cities, monthly rainfall and snowfall totals, and storm contracts on whether a named storm or a storm of a given category makes landfall within a defined window. The exact condition and source are set on each market page.
Forecasts sharpen as the event approaches, so the implied probability on a short dated weather contract can swing as new model runs and observations arrive. That uncertainty cuts both ways and is a core reason these markets carry a real risk of loss.
