How to Hedge with Prediction Markets: A True Story from the Travelers

By capper's founder

On a Monday morning in June I watched two golfers walk to a sudden-death playoff knowing my account got paid whichever one made the putt. That is what a hedge feels like, and it took one weekend and about fifty dollars to learn. Here is the concept, the math, and the whole messy, true story.

Hedging has a reputation as something hedge funds do, which is fair, since they named themselves after it. But the idea fits in one sentence: a hedge is a second position that pays when your first one fails, sized so you come out fine either way. Prediction markets happen to be the best hedging tool a sports fan has ever had, because every outcome has a live price you can buy at any moment, including the exact moment your original opinion starts looking shaky.

The concept article for this whole series explains the mechanics of buying and selling these contracts (how prediction markets work). This one is about the move that changes how weekends feel: turning "please hold on" into "either way works."

The one-line math

Prediction market contracts pay $1 if the outcome happens and $0 if not, so hedging arithmetic is friendlier than any sportsbook version.

Suppose an event is down to two realistic outcomes, and you hold S shares of side A. Buy S shares of side B, whatever B costs, and your final payout is locked: exactly S dollars, whichever side wins, minus what you paid for the hedge. Matching share counts is the whole trick. Your locked profit is:

Locked result = S − (cost of the B shares) − (what you originally paid for A)

The beautiful part is that a good hedge is often cheap. If side B is trading at 10¢, locking a two-horse race costs a dime per dollar of payout. The cheaper the other side, the less certainty costs. Keep that in mind when we get to the rain delay.

(If your original position is a sportsbook ticket instead of contracts, the same logic works with one extra step; the worked version is in prediction markets vs sportsbooks.)

The story: one bonus, five days, eight trades

This is a real account of my first weekend on a prediction market, at the Travelers Championship in June 2026. The tournament details are a matter of public record; the dollar figures below come straight from my Polymarket trade history.

The entry. I had a $50 signup bonus on Polymarket US to play with while my first deposit cleared. Scottie Scheffler, the best golfer alive, opened the tournament hot. His "to win" contract was sitting at 22¢, which felt low for how he was playing. I put the whole $50 on it. That bought me a couple hundred shares: if Scheffler won, they'd pay a dollar each; if not, nothing. So far, this is just a bet with extra steps.

The first lesson: you can take some off. By the end of day one Scheffler's contract had more than doubled, to around 55¢. At a sportsbook, that improvement would be a warm feeling and nothing else. On an exchange it is money, so I sold a slice, $14.50 worth, and kept the rest of the position riding. House money in one day. Later in the weekend, on another Scheffler surge, I peeled off a second slice, $26.57 this time. Remember those two peels; they matter at the end.

There was a second lesson hiding in what I did with that first slice: cheap contracts on live players. I rolled it into Viktor Hovland at 10¢, two strokes back. When Hovland tied the lead the next day I sold into the spike: $14.49 in, $53.70 out. Then on the final day I tried the same move with Wyndham Clark, two back and playing a great round. Ten dollars in, $11.95 out. Two dollars of profit on the move that had just returned nearly four times its cost. Not every flip flies. Either way, none of these were predictions about who would win the tournament. They were trades on the market's reaction to a leaderboard that kept moving, which is a smaller and much easier question (why these prices swing so hard).

The hedge. Late Sunday: Hovland one stroke behind with a few holes left, me still holding what remained of the original Scheffler stack after the two peels. Then the sky opened. Rain delay. Hovland's contract was sitting at 9.9¢, and it occurred to me that a long break might help the guy chasing. So I put $10 on Hovland, not as a prediction, but as the other side of my Scheffler position.

Here is the part I only appreciated afterward. Ten dollars of dime-priced Hovland bought me nearly a hundred shares of the other side. The counts were looser than the formula at the top of this article calls for, since my remaining Scheffler stack was bigger than that, but it changed what the playoff meant. Whichever name ended up on the trophy, my account was getting paid. The tournament was heading somewhere dramatic. Financially, I had great seats and no downside.

The finish. Sunday ran out of daylight with both men at 21 under. The playoff went to Monday morning. Hovland birdied the first extra hole, Scheffler missed a four-footer to match, and it was over. My original pick, the one I put the whole bonus on, lost. Run the Scheffler line by itself and it lost money: $50 in, $41.07 back across the two peels, the rest dead at settlement, about nine dollars gone net. The week still finished a bit under $120 up. The hedge paid out $96.66 the moment Hovland's putt dropped, and the flips had banked the rest.

Run that weekend back at a sportsbook: $50 on Scheffler at the same implied odds, five days of sweating, one short missed putt on Monday, ticket dead, total loss. Identical opinion, identical golf, opposite outcome. The difference: on an exchange, the position stayed alive. Sellable, hedgeable, adjustable, the entire time.

What the story generalizes to

A hedge is just a trade you make with new information. Every hedge in that story was a reaction to something the opening line couldn't know: Scheffler doubling, Hovland tying, rain. The market reprices all weekend; hedging is simply using those prices when they favor you.

The endgame is the cheap part. Down the stretch, a two-horse race means the trailing side is cheap. Putting a floor under my weekend cost $10 because Hovland was at a dime. Waiting for clarity and then buying certainty at the end is often the best-priced trade of the whole event.

Peeling is a half-hedge. Selling part of a winner, like the two slices I took off Scheffler on his way up, is the simplest risk reduction there is. No opposing position, no math, just less exposure. If full hedging ever feels complicated, start there. And notice what the peels did structurally: by shrinking the original stack, they made the endgame cheaper to protect. Taking profits early makes guarding the endgame easier later.

Your thesis can be wrong and your weekend can still be right. This is the deepest one. The original $50 opinion, Scheffler wins, was incorrect. Trading around that opinion still more than tripled the bonus. Sportsbooks settle your opinion; markets let you manage it.

When to hedge (and when not to)

Honesty requires this section: a hedge is not free money. When the market's prices are fair, hedging costs a little expected value, the same way insurance does, in exchange for certainty. So:

Hedge when the locked number is meaningful to you (a great weekend is on the table and you'd hate yourself for giving it back); when the position got large relative to your account by accident of a price run; or when you have a live read the market hasn't priced yet, like a rain delay that helps the chaser.

Don't hedge when the position is small, the guaranteed number barely differs from just selling (selling is also always available), or you'd be paying a wide spread in a thin market for the privilege (check the book first).

And the mechanical checklist, all three covered in this series: find the truly opposing contract, match your share counts for a full lock (or fewer for a partial one), and use limit orders so fees and spread don't eat the certainty you're buying.

The bottom line

Hedging on a prediction market is simpler than its reputation. Outcomes have live prices, so when your position and the world start disagreeing, you can pay a market rate, sometimes a dime, to stop caring which of them is right. I learned it during a rain delay, holding shares of a golfer I'd picked against my original guy, and the Monday playoff that followed was the most relaxing sweat of my life. Most of the proceeds are sitting in a contract on Argentina to win the World Cup as I write this, still open.
