2027 World Series Betting & Odds

Online sportsbooks prominently feature World Series winner odds shortly before the Fall Classic begins. This bet involves picking which of the two teams will prevail in the best-of-7 series.

Here’s an example:

• LA Dodgers -150 to win the Series – You’re betting $150 for every $100 in potential profit.
• NY Yankees +125 to win the Series – You’re risking $100 for every $125 in potential winnings.

What’s nice is that you’re not relying on a single game to be successful. Instead, you can lose some games and still win as long as your team is the first to four.

Of course, the goal isn’t necessarily to guess who wins. You also need to consider the value you’re getting on each team. At this stage, there’s not much separation in terms of talent between the favorite and underdog.

Oftentimes a big market team or one with a strong narrative will draw lots of public betting action. But that same squad might only have 55–60% true odds of winning versus the public treating them like an 80%+ favorite.

Another strategy is to hedge your series bet with wagering on a single game later. For example, you might bet on the favorite winning the Series and see them go up 3–2. This creates a hedging opportunity by taking the underdog to win Game 6.

Also consider that you don’t have to wait until right before the Fall Classic to bet. World Series futures can provide plenty of value, especially during the preseason, after free agency, and following the trade deadline. These markets are more inefficient than betting on the Series winner once it’s down to just two teams.

One of the most challenging—yet potentially rewarding—markets is betting on the correct Series score. Instead of simply picking the winner, you’re calling exactly how many games the champ wins and loses. This creates a higher degree of difficulty that’s offset by bigger payouts.

Here’s an example of World Series correct score odds:

• Seattle Mariners 4–0 — +675
• Seattle Mariners 4–1 — +525
• Seattle Mariners 4–2 — +425
• Seattle Mariners 4–3 — +350
• New York Mets 4–0 — +900
• New York Mets 4–1 — +750
• New York Mets 4–2 — +675
• New York Mets 4–3 — +550

The first number is how many games the listed team will win, while the second represents how many they’ll lose. Sweeps have the longest odds because they happen the least. The odds are more condensed for results ranging from 4–1 to 4–3 since they’re all possible outcomes.

Here are the probabilities of each outcome dating back to 2006:

• 4–0: 2007, 2012 (10% of the last 20 World Series)
• 4–1: 2006, 2008, 2015, 2020, 2023, 2024 (30%)
• 4–2: 2009, 2010, 2013, 2018, 2021, 2022 (30%)
• 4–3: 2011, 2014, 2016, 2017, 2019, 2025 (30%)

You’re best off avoiding sweep bets because they’ve lost 90% of the time over the past 20 years. The other outcomes are evenly distributed, meaning you’ll need to closely analyze the teams involved before deciding.

For example, a strong favorite has a good chance of winning 4–1 or 4–2. Meanwhile, a slight favorite is more likely to need seven games if they win.

As for more recent history, the Series has reached seven games in 4 out of the last 10 years (40% probability). The remaining results are split between five and six games, with both outcomes happening three times (30% apiece). The last time a sweep happened was 14 years ago.

Power hitting grabs voters’ and fans’ attention alike during the Series. Over the past 20 years, 10 MVP winners have hit at least two homers. This trend has been even stronger within the last decade, as six winners have cleared the fence 2+ times.

That said, slugging should be a big consideration when you’re betting on who hoists the next Willie Mays award. But a player doesn’t necessarily have to be Cal Raleigh or Aaron Judge to win.

We recommend looking at strong all-around players who have good power at their positions. For example, SS Corey Seager won MVP awards in 2020 (2 HR) and ‘23 (3 HR) through the long ball. Seager has never topped the home run leaderboards, but he’s good at going deep compared to other shortstops.

Speaking of which, shortstops have won the most MVPs among fielders in recent years. Five infield generals have captured the award since 2006, including 3 of the last 6 winners.

They’re always in the running because they can make outstanding defensive plays that stand out in voters’ minds. One diving grab followed by a double play could be a signature moment, especially if it’s a game-decider. Combine 1–2 memorable defensive plays with clutch hitting, and you have a strong candidate.

A dominant pitcher can’t be counted out with World Series MVP odds. Four hurlers have won in the past 20 seasons, with Dodgers ace Yoshinobu Yamamoto being the most recent.

Of course, being a top pitcher alone doesn’t indicate a future winner. As you’ll notice throughout MLB Playoffs betting, plenty of greats fall by the wayside before the Series starts. A potential MVP-winning pitcher needs to satisfy most of the following conditions:

• Clear ace: Starting Game 1 usually ensures two starting appearances during the Series. It also gives the pitcher a headliner quality that boosts their case. Yamamoto showed that starting Game 2 can also work when a team has multiple aces.
• Champion: No hurler has ever won the MVP on the losing side. Your pick not only needs to be great on the mound but also spraying champagne after the Series.
• Durability & Willing Manager: A pitcher benefits from going 6–7+ innings so they get the most credit for a win. Pair this with a manager who prefers letting their starter go deep into games. Bonus points if the pitcher can come back on short rest or even as part of the bullpen.
• Strikeout King: Big strikeout numbers and an unhittable appearance look better than fly balls and groundouts. Check K/9, WHIP, and the opponent’s batting average to find value here.
• Strong Narrative: Winning the MVP isn’t just about finding the strike zone. Great storylines help, like a pitcher dominating throughout the entire playoffs or living out a redemption arc.

Home teams tend to start out well in the World Series. Over the past decade, they’ve gone 7–3 in Game 1 and 6–4 in Game 2. That’s a 65% win rate, meaning taking the host’s moneyline in the first two games has been a good bet recently.

Things have been more even over the past 20 years, although trends still favor home teams. They’re 12–8 in Game 1 and 11–9 in Game 2, which is good for a 57.5% combined win rate.

What about your chances of winning both moneylines during the favorite’s first two games? The home side has won the first two games five times in the past decade (50%), while doing so nine times in the last 20 years (45%).

Given that recent trends suggest a 45–50% probability of home teams taking the first two, you may not want to blindly wager on them.

But when the home team jumps out to a 2–0 lead, you should strongly consider them for a Series bet. Hosts have won the Series 7 out of 9 times (77.8%) in the last 20 years after taking the first two.

The road team gets a single 3-game stretch to play at home and potentially swing Series momentum. It can use these middle contests to recover from going down 0–2, take control after a 1–1 split, or even finish off the Series after a surprising 2–0 start.

But it’s best to temper expectations when dealing with the visiting side since they’ve done well—not amazing. Here are recent results from road teams during their home stretch:

2016–2025 (24 total middle games)

• 15 wins
• 11 losses
• 57.5% win rate

2006–2025 (56 total middle games)

• 30 wins
• 26 losses
• 53.6% win rate

The numbers show that the Series underdog performs like a normal favorite once it gets back home. This trend has been increasingly true over the last decade.

The road team can really use these games to win the Fall Classic after a 1–1 split. They’ve won 50% of the last 10 Series after splitting the first two games, then using the middle contests to grab control.

This percentage isn’t incredible considering they essentially gain home-field advantage after stealing one on the road. But the underdog could still make for a good Series wager if you’re getting solid odds after a 1–1 start.
