The 2026 MLB Home Run Derby is going down at Citizens Bank Park on July 13th. It is the ultimate curtain raiser for the All-Star Game. Before the event, new traders can get $50 with the Polymarket promo code: PREDICTSAIL.
Bryce Harper (Philadelphia Phillies), Junior Caminero (Tampa Bay Rays), and Wilson Contreras (Boston Red Sox) are among the confirmed sluggers at this year’s Home Run Derby. That lineup snippet promises an event full of home runs. Here’s everything you need to know ahead of the derby and how you can claim your Polymarket bonus.
We are back at it again! July 13th is the MLB Home Run Derby. This 2026 edition comes with batting format changes. Sluggers will no longer be timed and expected to hit home runs in that time. Instead, they will now receive a set number of swings per round. Top sports prediction markets are reacting to these changes.
Junior Carminero of the Rays is the early favorite to win, according to early prediction market news on the event. He finished second last year, so he is best-placed to go a step higher. Despite his young age, he already has Derby experience, which should prove crucial for the Monday event. The unfinished business he carries over could also inspire him more. New debutants like Ben Rice of the Yankees add excitement to the roster and a challenge for the likes of Carminero, Derby title-chasing Contreras, and Bryce Harper, who’ll be at home.
