Can You Bet on the Weather? Legally, in All 50 States

Live in California, Texas, or one of the other states where online sportsbooks are still illegal? You can still legally trade on the outcome of real-world events — including the weather — on Kalshi, a federally regulated US exchange that operates in all 50 states. And because most people treat weather markets as a novelty, they're often mispriced — which is exactly where an edge lives.

Wait, you can legally bet on the weather?

Technically you're not "betting" — you're trading event contracts. Kalshi is a CFTC-regulated exchange (a designated contract market, the same category of regulator that oversees commodity futures). Instead of a sportsbook taking the other side of your wager, you buy and sell contracts with other traders. Each contract pays out $1 if the event happens and $0 if it doesn't, so the price — say 40¢ — is just the market's implied probability (40%).

Because it's a regulated exchange rather than a sportsbook, it's legal nationwide — no state license required, no geofencing you out in California or Texas.

What weather can you trade?

Kalshi lists daily markets for major US cities — the high temperature, the low temperature, and how much rain or snow falls. A typical market: "Will the high in Chicago be above 90°F today?" You can buy YES if you think it will, or NO if you think it won't, at whatever price the market is offering.

These settle on the official National Weather Service Climatological Reportfor a specific station — almost always the city's primary airport (New York settles on Central Park). That detail matters a lot, and it's where most casual traders go wrong.

Where the edge comes from

Two things create mispricing in weather markets:

• Thin attention. Far fewer traders look at weather than at, say, an NFL game — so prices drift from the true forecast.
• The wrong station. People eyeball the temperature on their phone (downtown) when the market settles on the airport, which can read a few degrees different.

The way to find value is to compare the market's implied probability against an independent forecast for the exact settlement station. If a reliable forecast says there's an 80% chance the high clears 90°F but the market is pricing YES at 60¢, that gap is your edge.

How Betstinct does it for you

That station-level comparison is tedious to do by hand for dozens of cities every day — so we automate it. Betstinct pulls every Kalshi weather market, runs an independent meteorological forecast for the actual NWS settlement station, and surfaces the markets where our model and the market disagree — but only when the recommended side is genuinely likely to hit, not a coin flip.

It's free right now during the 2026 World Cup. You can see today's weather edges on the Betstinct homepage, and every pick we post — sports and weather — is tracked publicly on our track record.

How to start

1. Open a Kalshi account (it's available in all 50 states).
2. Find a weather market for a city you can forecast — high temp is the easiest to start with.
3. Check an independent forecast for the airport, not downtown.
4. If the forecast and the market price disagree meaningfully, that's a potential trade — or let Betstinct flag it for you.
