Every innkeeper in a ski town knows the December feeling. The calendar is full, the deposits are in, and the whole month still hangs on one forecast nobody controls.
Now there’s a market for that feeling. Compass Vermont reported on October 26 that Kalshi, the federally regulated prediction market, is pitching ski-town businesses on a contract asking how much snow Stowe Mountain Resort will record by December 24. Kalshi’s marketing email held up a Big Sky vacation-rental manager who bet against heavy early snow there as “a cheap risk management tool.”
I think it’s a real tool. I also think most people who use it will buy the wrong line.
How the bet works, in plain English
Each contract pays $1 if the event happens and nothing if it doesn’t. A lodge worried about a thin start buys “No” on a snowfall line, so it gets paid when the snow doesn’t show. It’s insurance you buy by the share.
Kalshi isn’t freelancing here. It has been self-certifying ski-resort snowfall contracts with the CFTC, including a September 22 filing for Banff Sunshine Village, with other September filings naming Killington, Telluride and Alta. These products are spreading across the map.
Here’s what Stowe’s lines cost as of October 23, per Compass Vermont. Stowe averages about 55 inches by Christmas Eve, according to the OnTheSnow history the outlet cites.
| Snow line by Dec. 24 | ”No” price | Pays when | Hedge or wager? |
|---|---|---|---|
| 45 inches | 35¢ | Slow start | Real hedge |
| 55 inches | 51¢ | Below-average start | Coin flip |
| 65 inches | 65¢ | Anything short of big | Expensive wager |
At the 55-inch line, about $5,100 buys a $10,000 payout before fees. A normal start loses the $5,100.
The math that matters for a lodge
Insurance should be cheap and pay in the bad year. The 55-inch line is neither. You’re paying half the payout for a contract that triggers in plain below-average winters, the kind most bookings survive.
The 45-inch line is closer to what a hedge looks like. $3,500 buys the same $10,000 payout, and it only pays in the slow start that actually hurts. For scale, the Stowe Reporter recorded skier and rider visits falling 18 to 20 percent in the thin 2015-16 winter. That’s the year you want covered, not an average one.
So here’s my rule of thumb. Size the payout to the revenue you’d lose in a bad Christmas week, buy the low line, and never spend more than you’d shrug off in a normal year.
Why Vail’s CEO won’t touch it
Vail Resorts, which owns Stowe, isn’t hedging. CEO Rob Katz told Semafor in May that a clean weather hedge is “not as simple as it might look.” His point: timing and temperature drive the damage, not just the total.
He’s right, and the 2015-16 numbers prove it. Stowe’s snowmaking kept dozens of trails open that winter, and visits still fell. A storm on December 22 can pass the 55-inch line while every December weekend before it went brown. You can win the bet and lose the month, or the other way around.
That’s basis risk, a term for the gap between what the contract pays on and what actually costs you money. For a lodge, the real driver is last-minute bookings. Is snow total the thing that moves them, or is it the photos on your feed the week before?
The part every resort marketer should notice
Per Compass Vermont, the Stowe market settles on the resort’s own snow report. That number used to be a marketing asset. Now it’s also a settlement price with real money riding on it.
If your mountain’s report ever ran a little generous, this is the season that habit gets audited by strangers. Our take on snowfall averages as marketing claims just got a lot less theoretical. Measure the same way every time, publish the method, and let the snow speak for itself.
What I’d do this week
- Pull last December’s bookings by week and find the dollar gap between a good and a bad holiday week.
- If you hedge at all, buy the low line, sized to that gap. Talk to your accountant first; this isn’t financial advice.
- Spend the rest of the worry on things you control: flexible rebooking terms, a non-snow itinerary page, and early snowmaking footage.
A prediction market can soften a bad December. It can’t sell one. Would you put lodge money on your mountain’s snow report, or does that feel like betting against your own house?
