2026 Home Run Derby Participants and Odds

MLB scrapped the clock this year and returned to a swing-based format. Each hitter gets 20 swings in Round 1 and 15 in the semifinals and final. The top four first-round performers advance, and any player who homers on his final swing keeps hacking until he misses. Citizens Bank Park rates as the fifth-best home run park in baseball, so expect fireworks.

A stacked bunch from the best MLB lineups have committed, as the full field has now been set:

• Kyle Schwarber, Phillies (DH) — A hometown hero who leads Kalshi in the odds race to win the Home Run Derby thanks to 56 home runs last year, and 32 this season.
• Junior Caminero, Rays (3B) — The 2025 runner-up returns red-hot with 26 homers and a recent stretch of long balls in six straight games.
• Bryce Harper, Phillies (1B) — Another hometown hero won the 2018 Derby in his home park in Washington and now chases a second title in front of Philadelphia.
• Jordan Walker, Cardinals (RF) — The 6-foot-6 breakout star ranks in the 100th percentile in bat speed and leads MLB with 70 RBIs.
• Ben Rice, Yankees (1B/DH) — A first-time All-Star with 26 homers who will have his father, Dan, throwing to him.
• Jac Caglianone, Royals (RF) — Raw power personified, with a 418-foot average homer distance that ties for the longest in the majors.
• Willson Contreras, Red Sox (1B) — The 34-year-old is enjoying a career power year with 20 homers in his first Derby.
• Munetaka Murakami, White Sox (1B) — The 26-year-old White Sox star has recorded 20 homers throughout his rookie season in the majors.

Prediction market apps are still setting full win prices ahead of first pitch, but the early market read is clear:

• Schwarber, Caminero, and Murakami headline the favorites, Caminero is riding a hot streak, Schwarber draws hometown energy, and Murakami provides fun upside. .
• Walker, Harper, Caglianone, and Rice form the boom-or-bust middle tier, each armed with elite exit velocity but real swing-and-miss risk under pressure.
• Contreras sits as the longest shot, since he pulls to the opposite side of the park’s lefty-friendly dimensions.

Polymarket prices each contender as a live contract, so implied odds shift in real time as swings pile up. That live movement gives you a sharper read than a static odds board.

FantasyLabs tracks these markets closely and stands behind the numbers we publish, which is why readers trust us to verify prices and promos before they trade. Also trust the best Polymarket promo code MLB enthusiasts can claim today is LABS from FantasyLabs.

Why Polymarket Promo Code MLB Fans Should Redeem is LABS

Polymarket runs as a CFTC-regulated prediction market rather than a traditional sportsbook. You buy and sell shares tied to yes-or-no outcomes, and the price of each share reflects the market’s implied probability. A contract trading at 40 cents signals roughly a 40% chance, which makes the math intuitive.

Three features make Polymarket especially fun for baseball fans. First, the Polymarket promo code MLB fans should redeem is LABS, as $50 in bonuses are up for grabs with one of the best prediction market promos.

Second, you can enter and exit positions mid-event, which fits a Derby where momentum swings round to round. Third, the app translates prices into standard American odds. This means newcomers feel at home while sharper traders toggle to cent-based pricing.

The depth goes well beyond one night. Trade MLB game winners, futures, and player markets all summer, then branch into the World Cup, politics, and more. For an event like the Home Run Derby, that flexibility turns a single contest into a live, tradable market.

My 2026 MLB Home Run Derby Pick

Take Junior Caminero to win it all. He enters on the hottest power streak in baseball. The swing-based format rewards a hitter who barrels the ball as consistently as he does right now. Caminero fell one round short last year, and that experience matters in a format built on efficiency. The raw talent, the timing, and the motivation all line up. Trade your Polymarket bonus on Caminero before first swing.

Must be 18 or older with a legal U.S. residential address in an eligible state. Not available in AZ, IL, MA, MD, MI, MT, NJ, NV, and OH. Please play responsibly.
