Post-Trade Deadline Winners
⬆️ Los Angeles Dodgers (+150)
The rich get richer as the back-to-back defending World Series Champions just got even better after the 2026 trade deadline, acquiring two-time Cy Young winner Tarik Skubal from the Detroit Tigers. With one of the best arms in the MLB now added to their already stacked bullpen, the Los Angeles Dodgers are by far and away the most talented team in baseball. With their sights set on the first World Series three-peat since the New York Yankees from 1998-2000, the Dodgers superteam is hard to bet against.

⬆️ Boston Red Sox (+1500)
After starting the season off terribly, the Boston Red Sox have bounced back in a big way, now sitting as one of the top contenders for the 2026 World Series Trophy. Not wanting to sit on their hands, the Red Sox made big moves at the trade deadline, acquiring catcher Adley Rutschman from the Baltimore Orioles and pitcher Erik Miller from the San Francisco Giants to help bolster their roster heading into an aggressive postseason push.

⬆️ Houston Astros (+2500)
To the dismay of Toronto Blue Jays fans, the Houston Astros saw their World Series odds spike after making a deal to acquire Golden Glove winner Dalton Varsho at the trade deadline. One of the top outfields in the game, the Astros are now in a position to run away with the AL West division title, making their push to claim their third World Series Trophy in 10 years.

Post-Trade Deadline Losers
⬇️ Seattle Mariners (+2200)
After narrowly missing out on a World Series appearance in 2025, the Seattle Mariners haven’t replicated their success from a season ago and now sit on the outside looking in on the AL Wild Card Race. While they did acquire outfielder Taylor Ward to try and bolster their bats, the Mariners sent away three-time All-Star pitcher Luis Castillo to the Chicago White Sox. Without their teams top Ace on the mound, the Mariners arguably got worse at the deadline, hurting their playoff chances, and ultimately dropping their World Series odds.

⬇️ Texas Rangers (+3500)
Another AL West team that hurt their stock this trade deadline, the Texas Rangers, did a whole lot of nothing. Potentially lowering their ceiling in terms of outright talent after shipping out utility player Josh Smith and prospect Josh Stephan in return for relief pitcher Adam Macko, the Rangers may only be two games out of a Wild Card spot, but certainly didn’t do themselves any favours with this mediocre return.

⬇️ Baltimore Orioles (+10000)
It was a fire sale in Charm City this trade deadline as the Baltimore Orioles said goodbye to several of their top talents as they officially threw in the towel on their 2026 campaign, and possibly beyond. Parting ways with the aforementioned Adley Rutschman, as well as pitchers Taylor Ward, Tyler Wells, and Joe Glassey, the Orioles were already on a downward spiral, but this past trade deadline officially put the nail in the coffin of their 2026 campaign.
