No snow, no season: how a ski resort can hedge a bad winter

A ski resort is one of the most weather-exposed businesses there is. Almost all of the year's revenue is earned in a few winter months, and how good those months are comes down to something nobody controls: snow. A warm, dry December can gut a season before the holidays even start, while the resort's costs — staff, lifts, snowmaking, financing — carry on regardless. This is a case study in turning "will it be a good winter?" from a nervous hope into a number the resort can actually plan around.

The problem: fixed costs, snow-dependent revenue

Picture a mid-sized Alpine resort. It needs roughly a full season of open days to hit its budget, and its costs are largely fixed: it pays for lift maintenance, seasonal staff and loan repayments whether the slopes are busy or bare. The revenue on the other side of that ledger is anything but fixed — it swings with skier-days, and skier-days swing with snow.

Let us put rough, illustrative numbers on it. Say a normal season delivers around €150,000 of gross profit that a poor snow year would wipe out — through fewer open days, thinner crowds and a fat energy bill for running snow cannons on marginal nights. The resort cannot budget for that swing, because it only lands in the years the weather turns against it. That is the trap of a weather-driven business: the downside is real, sizeable and completely outside your control.

If the idea of pricing an uncertain event is new to you, our primer on what a prediction market is covers it in a couple of minutes, and reading the odds explains why a price in cents is really just a probability.

The hedge: buy the bad winter you are afraid of

A prediction market lets the resort buy the exact outcome that hurts it. Imagine a market on "Will this be a poor snow season?" — defined cleanly, say, as fewer than a set number of open days or a snowfall total below a published threshold. A Yes share on that market pays out 100¢ if the poor season happens and 0¢ if it does not.

Suppose Yes is trading at 25¢. The market is saying there is about a 25% chance of a bad winter. To cover the €150,000 the resort would lose in that scenario, it buys enough Yes shares to pay out €150,000 on a Yes resolution. At 25¢ each — each share returning €1 if the bad season materialises — that is 150,000 ÷ 1 × €0.25 = €37,500 up front.

Now trace both outcomes:

• Bad winter. The resort loses about €150,000 of gross profit, but its Yes shares pay out €150,000. The shortfall is covered. Net cost of the whole exercise: the €37,500 hedge.
• Good winter. The resort earns its full season revenue and the €37,500 hedge expires worthless — cheap insurance you were delighted not to need.

Either way, the swing has been converted into a fixed €37,500 cost, decided before the first snowflake rather than by the weather. That is the same logic a resort already uses when it insures a chairlift; here it is insuring the season itself.

The unit economics

The €37,500 is not a loss — it is the price of certainty, and the maths is fair rather than a gamble. The market's 25¢ implies a 25% chance of a bad year, so the resort's expected weather loss is about 25% × €150,000 = €37,500 — exactly what the hedge costs. The resort is paying the honest expected value of its risk up front, and what it buys is the removal of variance: no year where an empty slope quietly blows a €150,000 hole in the accounts.

Set against the size of the business, that is a modest premium for sleeping through a dry December. It also makes the resort easier to finance and plan: a lender or a landlord is far happier lending against a season whose worst case is capped than one that could swing by six figures on the weather. This is the same playbook we walk through for festivals and outdoor events in hedging weather risk for outdoor events — the scenario changes, the mechanics do not.

Where it breaks — and how to keep it clean

A few honest caveats. The biggest is basis risk: the market resolves on a snowfall or open-days metric, not on your actual takings. If a resort has a poor commercial season for a reason the market does not capture — a strong franc keeping foreign visitors away, say — the hedge will not respond. Size the hedge to the part of your risk that genuinely tracks snow, and no more.

Then there is liquidity. A €37,500 position needs a market deep enough to fill without moving the price against you, so a thin, exotic snowfall market may not carry it — build the spread and fees into your costing. And write the trigger tightly: "fewer than X open days by 31 March" resolves cleanly, whereas "a bad winter" is an argument waiting to happen. The tighter the wording, the tighter the hedge.

The same structure travels well beyond the mountains. A summer festival can hedge a rain-out, a hotel can hedge a washed-out bank holiday, a farm can hedge a drought. Anywhere a business's revenue is hostage to a measurable public event, a prediction market can turn open-ended weather risk into a fixed, plannable number.

The best way to get a feel for it is to try it without a season on the line. On Outcomer you can practise sizing and placing exactly this kind of hedge with virtual money — run a mock "bad winter" position, watch how the price tracks the probability, and see how the payouts fall out before you ever risk a real euro.
