2026 MLB Home Run Derby Prediction Markets: Best Trades to Consider & Analysis

By Frank Ammirante | Jul 12, 2026, 2:01pm

The 2026 MLB Home Run Derby is upon us. It’s always a fun time to watch some of the best power hitters in the game flex their talents. This year, I’m even more intrigued than usual, since we have several young stars competing, including Junior Caminero, Munetaka Murakami, Jac Caglianone, and Jordan Walker.

The best place to engage with the Home Run Derby is at prediction markets. These are platforms where you can buy and sell positions on the Home Run Derby. This includes dynamic pricing, which is set by the market.

My favorite part about trading on prediction markets is that you can exit your position by selling it for a profit before it settles. one good way to do this is by targeting a longshot, then if they advance to the next round, you can earn a small profit. You can always hold until the end as well, but having the option to sell early gives you more flexibility.

On this page, we’re going to explore Home Run Derby prediction markets, focusing on Polymarket, since they have so many options available for you.

What Are Prediction Markets?

Prediction markets offer a different way to follow the Home Run Derby than placing a traditional sportsbook wager. Rather than betting against a bookmaker, users buy and sell contracts tied to Derby outcomes, with prices changing throughout the event based on market activity and perceived probabilities.

These platforms function more like exchanges than sportsbooks. Participants trade contracts on specific outcomes, such as which player will win the Home Run Derby or whether a hitter will advance to the next round.

Most contracts are based on a simple binary format: “Yes” or “No.” Contract prices generally range from $0 to $1, with the price representing the market’s estimated probability of that outcome.

A Kyle Schwarber contract trading at $0.20 suggests the market believes he has roughly a 20% chance of winning the Home Run Derby.

When the Derby ends, winning contracts pay $1 each, while losing contracts expire with no value. Because prices fluctuate before the event is decided, traders can also exit their positions early. For example, if you buy a Kyle Schwarber contract at $0.20 and its price rises to $0.40, you can sell it before the Derby concludes and lock in a profit.

Some of the prediction market platforms offering Home Run Derby contracts include:

Prediction Markets vs. Traditional Sportsbooks

Prediction markets provide a different way to participate in the Home Run Derby than placing a futures bet at a traditional sportsbook. Instead of locking in fixed odds from a bookmaker, users purchase and trade contracts tied to Derby outcomes, with prices updating throughout the event as expectations change.

Here’s what sets prediction markets apart from sportsbooks:

Odds aren’t set by a sportsbook. They’re determined by market participants.
Contract prices rise and fall based on real-time buying and selling.
Users can sell their contracts before the Derby is over instead of waiting for settlement.
The current contract price reflects the market’s implied probability of an outcome.
Participants trade on an exchange rather than wagering directly against the house.

Most Home Run Derby markets use “Yes” and “No” contracts. Prices range from $0 to $1, with each contract paying $1 if the prediction is correct and $0 if it isn’t.

Example: Trading Junior Caminero to Win the Home Run Derby

Assume Junior Caminero is trading at $0.18, meaning the market currently gives him an 18% chance of winning the Home Run Derby.

Here’s one possible scenario:

You buy 100 “Yes” contracts at $0.18 each.
Your total cost is $18.

After a strong performance in the opening round, demand for Caminero contracts increases and the market adjusts.

For example:

His contract price climbs to $0.40.

At that point, you have two options:

Option 1: Sell your position

Sell all 100 contracts at $0.40.
You receive $40.
Your profit is $22.

Option 2: Hold until the Derby ends

If Caminero wins the Home Run Derby, your 100 contracts settle for $100.
If he falls short, the contracts expire at $0, and you lose your original $18 investment.

This ability to buy and sell throughout the event is one of the biggest differences between prediction markets and traditional sportsbook futures, which generally can’t be traded once the bet has been placed.

Home Run Derby Markets

In this article, we’re going to focus on the following Home Run Derby markets from Polymarket:

Winner
Player with Most HRs in a Single Round
Number of Bonus Swing HRs
Home Run Derby Swing Off?

Winner: Jac Caglianone (13¢)

Jac Caglianone looks like a terrific value to win the Home Run Derby. This is a hitter with 77.3 MPH bat speed (97th percentile) and a 14.9% barrel rate (91st percentile). While he doesn’t have the same gaudy numbers as other power hitters in this competition, like Kyle Schwarber and Junior Caminero, Caglianone has elite raw power.

The young Royals’ slugger will have an opportunity to make a name for himself by winning the Home Run Derby. That added motivation, coupled with the bat speed and batted ball metrics, makes Caglianone worth a look. Remember, this was a highly-touted prospect. He’s finding his groove in the big leagues, coming off a monster June, so we’ll take a shot on him here.

Players with Most HRs in a Single Round: Junior Caminero (14¢)

There’s no hotter hitter on the planet than Junior Caminero right now. The Rays’ slugger has homered 13 times since June 23rd. He’s on a special type of power binge. This kind of streakiness is exactly what I’m looking for when targeting a hitter to put up the most home runs in a single round.

On top of that, Caminero similarly has an elite barrel rate (85th percentile) and bat speed (100th percentile). With some of the fastest bat speed since MLB started tracking this stat, Caminero is the ideal profile for a hitter who can slug home runs in bunches. At 14 cents, this looks like a nice value.

Number of Bonus Swing HRs 3+: No (50¢)

The last two markets have extremely low liquidity right now, with only $594 in volume on bonus swing home runs. With a volatile market like this, it’s best to just play it safe by going with the lowest price, as the other outcomes are currently at 90 cents or greater right now. That’s why we’ll take fewer than three bonus swing home runs.

The way it works is that if a player homers on their last swing, they get a bonus swing. From there, if they need to homer in their next swing. In other words, you’re buying shares on a home run on back-to-back swings. I’ll go with “No” on that one.

Home Run Derby Swing Off? Yes (48¢)

This is another low-volume market, currently at only $22. Your only option right now is to take yes on a Home Run Derby swing off at 48 cents. With how closely contested the field is, it feels likely that at one point, it’ll come down to a swing off to decide the winner. At 48 cents, the price is reasonable.
