Weather Prediction Markets: Where to Trade On The Forecast in September 2026
A weather forecast is really just a probability dressed up as a number. Weather prediction markets take that same idea and let you trade it directly, buying a “yes” or “no” contract on whether a specific temperature, storm, or weather event occurs.
Coverage ranges from something as narrow as tomorrow’s high in a single city to season-long questions about hurricane activity. Since weather data is public and constantly updated, these markets tend to move quickly, and there’s rarely a shortage of new trading opportunities.

What are weather prediction markets?
A weather prediction market is a place where people trade contracts based on the outcome of a real weather event. Each contract asks a specific yes-or-no question, such as “Will the high in Chicago hit 90 degrees today?” or “Will a named storm make landfall in Florida this week?”
You buy a “yes” contract if you think the event will happen, or a “no” contract if you think it won’t. The price of each contract ranges from 1 cent to 99 cents, and that price reflects what other traders think the odds are. A contract trading at 80 cents is telling you the market sees roughly an 80 percent chance of that outcome.
If you’re right, your contract pays out at $1. If you’re wrong, it pays out at nothing. Because the risk is capped at what you paid, it plays out differently than trying to hedge weather risk any other way.
Is trading on weather markets legal?
Yes, in the US, trading on weather outcomes is legal on regulated platforms such as Polymarket and OG. These platforms operate under the Commodity Exchange Act and are regulated by the Commodity Futures Trading Commission (CFTC), which treats these contracts as regulated derivatives rather than gambling products.
Weather contracts sit in a slightly different spot than, say, sports or politics, since insurers and commodities traders have used weather derivatives for years in a more institutional setting. Retail platforms have made that same idea accessible to everyday traders. Availability can still vary by platform and state, so check before signing up.
Weather platforms compared
Prediction market platforms all take a different approach to weather trading, and coverage depth varies more here than in other categories.
FanDuel Predicts

Trade on Sports to Culture, Financials, Crypto and More
At last check, FanDuel Predicts did not have a category for either weather or climate markets. The platform is still relatively new, however, and continues to build out its lineup, so it is worth keeping an eye out for these markets perhaps being added down the road, especially if you’re already using the app for sports or other categories.

Polymarket runs one of the most comprehensive weather sections around, with markets on daily temperatures in major cities, hurricane formation and landfall, and even longer-running questions on global weather patterns. It’s a strong pick if you want more than just the occasional storm contract. Funding runs through USDC (a stablecoin pegged to the US dollar), so a crypto wallet is part of the setup.

Kalshi
Kalshi‘s weather section is the most detailed of any regulated platform, breaking down a single city’s forecast into several overlapping temperature brackets rather than a single broad call. Beyond daily forecasts, it runs standing categories for hurricanes and other natural disasters, which makes it a strong option if you want precision over a broad guess.
Robinhood
Robinhood added weather contracts through its Kalshi partnership, so daily temperature and storm markets show up right next to your stocks and crypto. It’s convenient if you’re already in the app, though the selection mirrors what Kalshi lists rather than something built independently.
Types of weather markets you can trade
Weather prediction markets cover more ground than a simple hot or cold call. Here are the categories you’ll run into most often.
Daily temperature brackets
These markets ask whether a city’s temperature will fall within a specific range on a given day. Because they settle quickly, they’re some of the most actively traded weather contracts day to day.
Precipitation and snowfall
These markets cover whether it will rain or snow at a specific location, sometimes to a measurable amount, within a set time window.
Hurricane and storm activity
These contracts track storm formation, paths, and landfalls, along with broader seasonal questions such as the total number of named storms. Trading volume tends to spike as a storm approaches a populated coastline.
Natural disasters
Beyond storms, some platforms list markets on earthquakes above a certain magnitude and tornado counts over a given stretch, often broken into numerical brackets like “more than 150 tornadoes in the US this month.” These tend to see the most activity during spring severe weather season.
Seasonal and climate trends
These longer-running markets ask about broader patterns, such as whether a winter will end up warmer than average or whether a particular year sets a new global temperature record. Some platforms go even further, listing contracts on things like Arctic sea ice extent or monthly CO2 readings, which are aimed at traders who follow climate science closely and are comfortable holding a position for months at a time.
How contract settlement works
Every weather prediction market contract resolves against a specific, verifiable data source, most often an official reading from a source like the National Weather Service. The market page usually names the exact station or data feed used, along with the precise time the reading is taken.
Weather settlement tends to be more objective than something like a mention market in pop culture, since a recorded temperature or confirmed landfall isn’t really up for interpretation. Still, it’s worth double-checking which station or source a contract uses, since readings can vary between nearby locations.
A common trap: you check the weather app and see a high of 91 degrees downtown, so you buy “yes” on a 90-degree contract, only to have it settle against the official airport station miles away, which read a few degrees cooler. You’re not trading the weather you feel; you’re trading the specific number a named station reports.
How to trade on weather markets
Getting started is more straightforward than most people expect. Here’s the general process.
- Sign up and verify your account: Register on a regulated platform and complete identity verification, typically using an ID and basic personal details.
- Deposit funds: Most platforms accept bank transfers or debit cards, while some rely on crypto deposits. Some offer a welcome bonus for new accounts.
- Browse weather markets: Look under categories like “Weather,” “Climate,” or a specific city name to find current questions you can trade on.
- Buy a contract: Choose “yes” or “no” based on your prediction, and pick how much you want to trade.
- Track your position: Forecasts update constantly, so keep an eye on your contracts as the settlement time approaches.
Fees to expect
Most weather prediction market platforms build their fee into the contract price rather than charging a separate flat fee, though this varies by site. Some platforms charge a small trading fee, often around 2 percent or less. You may also incur fees for deposits or withdrawals, depending on your payment method.
These fees are usually clearly listed on the platform, but it’s worth checking before you trade, especially during a major storm, when activity tends to spike.
How accurate are weather prediction markets?
Weather markets tend to be fairly accurate near settlement, since traders can rely on the same forecasting models meteorologists use. A same-day temperature contract, for example, benefits from hours of updated forecast data before it settles.
Accuracy drops the further out you go. A hurricane’s exact path five days out carries real uncertainty, and a seasonal climate question carries even more. Treat longer-running weather contracts with more caution than a next-day forecast.
Tips before you trade weather markets
Weather is more measurable than most other categories, so a little homework goes a long way here.
Keep position sizes modest: Even a well-forecast event can surprise you at the margins.
Understand the exact station or data source a contract uses: Two nearby locations can report slightly different readings.
Lean on short-term contracts while you’re learning: Same-day forecasts are more reliable than a five-day storm path.
Expect volume to spike around major storms: This usually means tighter pricing and more contracts to choose from.
Factor in the fee if you’re trading daily temperature contracts often: Small costs add up over frequent trades.
Weather Prediction Market FAQ
Yes, through regulated platforms like Polymarket and OG. These operate as federally regulated exchanges rather than gambling operators.
Daily temperature contracts in major cities and active hurricane markets tend to see the most trading volume, especially during storm season.
You can start with a small amount, since contracts are priced between 1 cent and 99 cents. Many traders begin with a modest amount to get familiar with how the markets move.
