Updated World Series Odds: Post-MLB Trade Deadline Betting Lines

The final 31 hours of the MLB trade deadline saw 50 trades made across the league, but none were impactful enough to drastically shake up the World Series odds market.

The Los Angeles Dodgers (+285) remain betting favorites to become baseball's first repeat champion since the New York Yankees at the turn of the century. The reigning pennant winners are one of five teams trading at shorter than 10/1 odds to win the 2025 Fall Classic at the best sports betting sites.

The other contenders are the Yankees (+900), Philadelphia Phillies (+900), New York Mets (+950), and Detroit Tigers (+1000), all of whom added pieces in the final hours before the trade window slammed shut. Let's break down the latest World Series odds following an active deadline day.

🏆 World Series odds favorites

🔵 Los Angeles Dodgers (+285)

📊 Best odds: +285 via DraftKings ($10 to win $28.50)
🔢 Implied probability: 25.97%

Los Angeles was relatively quiet during MLB trade deadline day aside from a handful of complementary moves. The Dodgers got most of their shopping done in the offseason, when they put on one of the more impressive team-building exercises in recent memory.

Dave Roberts' men came into the campaign as heavy betting favorites, and after posting an NL West-leading 63-46 record thus far, that's where they remain.

There have been bumps in the road for Los Angeles - specifically due to a lengthy injury list - but there's no doubt in the minds of oddsmakers at the best MLB betting sites that the Dodgers are clear World Series odds favorites.

🗽 New York Yankees (+900)

📊 Best odds: +900 via BetRivers ($10 to win $90)
🔢 Implied probability: 10%

---

Nobody had a busier deadline day than New York. And after the Yankees surrendered the top spot in the AL East to Toronto weeks ago, a shake-up was warranted.

Brian Cashman brought in a plethora of pieces to his 26-man roster, including these recent acquisitions:

• CP David Bednar
• RP Jake Bird
• INF Jose Caballero
• RP Camilo Doval
• 3B Ryan McMahon
• INF Amed Rosario
• OF Austin Slater

The importance of adding three strong relievers to one of baseball's most struggling bullpens cannot be overstated. New York also addressed its defensive issues in the infield. While the Yankees didn't make any splashes per se, a team with MLB MVP odds contender Aaron Judge doesn't require more star power to succeed.

New York was among the biggest risers on the oddsboard following the trade deadline. The reigning American League champions are now trading at 9/1, putting them level with Philadelphia as the top contenders to dethrone the Dodgers. 

🔔 Philadelphia Phillies (+900)

📊 Best odds: +900 via Caesars ($10 to win $90)
🔢 Implied probability: 10%

---

The Phillies' Achilles Heel in postseasons of years past has been the closing spot. Philadelphia has tried to plug and play different relievers in recent seasons, but nothing - not even future Hall of Famers - has seemed to work. David Dombrowski has his fingers crossed that all changes now. 

Jhoan Duran, one of baseball's best closers, made the switch from Minnesota and is expected to slot in immediately as a key to the Phillies' success. Unlike the Yankees, Philadelphia focused on quality over quantity at the deadline, also adding Twins OF Harrison Bader to bolster its lineup.

In addition to their in-season success, these trades rightfully position the Phillies as Los Angeles' biggest hurdle in the race for the National League pennant. The latest odds at the best sportsbooks give Philadelphia a 10% implied probability of winning the World Series for the first time since 2008.

🍎 New York Mets (+950)

📊 Best odds: +950 via FanDuel ($10 to win $95)
🔢 Implied probability: 9.52%

---

I've written ad nauseam already about contenders bolstering their bullpens ... but nobody did a better job of that than the New York Mets. The Mets brought in three household names - Ryan Helsley, Tyler Rogers, and Gregory Soto - to give the NL East leaders one of the deepest arm barns in baseball.

As we've seen in previous postseasons, a reliable bullpen matters more than perhaps any other position group in the playoffs. In other words, these additions are music to the ears of all of those in Queens.

New York also looked to address its joint-16th-rated offense (4.34 runs per game) by adding an outfield bat with a bit of experience in Cedric Mullins. Is he a game-changer? Not necessarily, but the Mets did enough to see their odds (+950) shoot down to below 10/1. It goes without saying they did something right.

🐯 Detroit Tigers (+1000)

📊 Best odds: +1000 via FanDuel ($10 to win $100)
🔢 Implied probability: 9.09%

---

Detroit's odds haven't moved all that much. However, nobody truly expected a seismic shift in a futures market that's anything but volatile after the moves the Tigers made.

Jeff Greenberg added a pair of starters - Charlie Morton and Chris Paddack - to step in for the injured Reese Olson. Detroit also acquired Kyle Finnegan, Codi Heuer, Rafael Montero, and Paul Sewald. All four relievers boast ERAs over 4.35, though, so there's not much hope they can help improve the Tigers' 19th-rated relief staff.

At the end of the day, Detroit's odds tell the story of what we've seen so far from the AL Central leaders, as opposed to what's expected from the Tigers in the coming months. They're already a virtual lock for the postseason - how far can Cy Young award odds favorite Tarik Skubal take them?
