    Odds To Win The World Series – Whose Odds Are Increasing?

    Atlanta Braves

    Atlanta opened with odd between +1000 and +1400. So it wasn’t so much a miracle run as it was a team that came together as good as they needed to for a shot at the championship. And while the Braves were the underdogs among the four NLCS and ALCS teams, they’re now officially sitting pretty.

    Sure, they’re the underdogs going into Game 1 against the Astros (+115 vs. -135 for the DraftKings moneyline). But the run line for the Braves is +1.5 (-180) while the Dodgers run line is -1.5 (+155). That tells us the sportsbooks think the Astros will eke out a win by one run, which isn’t exactly a clean bill of health.

    Houston Astros

    The Houston Astros were long-shots to win the 2021 World Series. Some sportsbooks offered +2200 odds on the team at the beginning of the season, which means a $100 bet would have paid out $2,200 if the team ends up going all the way. And it’s not unlikely.

    That’s become even more clear with the opening odds. DraftKings Sportsbook has the Astros as the favorite to win Game 1 of the 2021 World Series, with a -135 moneyline against a +115 moneyline on the Braves. The implied odds for the Astros to win is 57.45%. The implied odds for the Braves is 46.51%.

    Odds To Win The World Series – Who’s In Trouble?

    LA Dodgers

    The Los Angeles Dodgers were the favorite to win the 2021 World Series at the beginning of the season and pretty much all season long. But after losing to the Atlanta Braves in the NLCS, they’ll have to wait until next year to prove themselves worthy of a 2022 World Series run.

    Boston Red Sox

    None of the top four teams have seen such a meteoric rise to likely World Series contenders like the Red Sox. The Red Sox odds to win the 2021 World Series at the beginning of the season was +3000 at most sportsbooks. For game 3 of the ALCS, the team’s odds were +400 at BetMGM to win it all – and even shorter at other sports betting apps. Unfortunately for fans and Red Sox bettors, the team was eliminated in the ALCS against the Astros. But the ALDS title has to make Red Sox supporters hopeful going into the 2022 MLB season.

    What’s Different In The 2021 MLB Season?

    Return To The Traditional Schedule

    The 2021 MLB Season featured the full 162-game schedule, up considerably from the shortened season of 60 games last year. This year, the season began on April 1 and will end on November 3 assuming a seven-game World Series.

    Plus, the 2020 season restricted teams to playing other geographically close opponents throughout the regular season, and the postseason played out at selected neutral sites. For 2021, we’re back to normal, including full crowds at most stadiums by the middle of the season.

    Other 2020 rules changes, like the designated hitter applied to National League games, didn’t return for 2021 either.

    Where Can I Bet On The World Series Online?

    In the US, there are currently 26 states (plus DC) where sports betting is legal in some form. However, of those areas, these 17 states allow legal online sportsbooks, and the rest do not:

    States with legal in-person betting but not mobile betting include:

    • New York
    • Mississippi (in-person mobile betting)
    • Arkansas
    • Delaware
    • Montana
    • New Mexico
    • North Carolina
    • North Dakota
    • South Dakota
    • Washington

    Dozens of other states have considered legislation related to legalizing physical and online sports betting in 2020 alone. Much of this legislative moment came as a result of the overturn of PASPA, the law that prohibited online sports betting.

    In fact, around ten states will legalize online sports betting in some form by the end of 2021 or early 2022, including Connecticut, Maryland, New York, and Louisiana. Florida will also launch retail sportsbooks, and may also legalize online sports betting as well.

    Will All Legal US Sportsbooks Take Bets On The World Series?

    Yes. While some states bar residents from betting on in-state college games, you can always bet on the pros. And because the World Series is one of the biggest sporting events in America, it’s a safe bet that it will be well represented at every legal online sports betting site and app.

    It’s also likely that the standard sports betting odds on the World Series will be comparable across the options. That means if you make a straight bet on one of the teams, it doesn’t matter much where you place your bet as long as it’s a legal site. Still, it’s smart to shop around for the best odds, as the payout differences can be significant depending on how much you’re betting.

    Plus, the odds start to get much more variable with exotic bets and promotions. This is true with the MLB (and all sports) in general, but it’s in overdrive when it’s the World Series. From unique prop bets to odds boosters to deposit bonuses, each online sportsbook will have something interesting on offer.

    How To Place Online World Series Bets

    If you’re in a state where online sports betting is legal, placing a bet is relatively simple. Choosing the best bet is where things get a bit more tricky. But analytics aside here’s a step-by-step guide on online World Series betting:

    Choose A Sportsbook And Create An Account

    You’ll have a set number of options to choose from. States like New Jersey and Nevada have over 20 online sportsbooks while other states have just a few. Here are some factors to consider:

    • How good are the promotions?
    • How fair are the bonus terms & conditions?
    • Do they offer the best odds?
    • Can you play via mobile?

    Once you’ve selected an online sportsbook, you’ll create an account. Follow the steps that include providing your personal information, and you’ll need to allow the sportsbook to know your location. For all states, you need to be physically located in the state to bet.


    You may find a sign-up or registration bonus that gives you free money without the need to deposit. You may also take advantage of a deposit bonus where the casino matches your deposit by a certain percentage.

    Just be sure to read all bonus terms and conditions before you opt-in. You can always opt-out of the bonus offers and simply deposit.

    Deposit And Cashout

    Common deposit methods include credit and debit cards as well as e-wallets like PayPal. You can likely cash out using PayPal, direct deposit, or in-person at a partnering casino cage.

    Where Can I Bet On The World Series In Vegas?

    Las Vegas is such a sports betting hub that its sportsbooks play a massive role in setting the odds for all others to follow.

    You can bet on the World Series in Vegas at every one of the sportsbooks on the Strip. Westgate, Caesars, Wynn, Mirage, Venetian, you name it, they’ll take a wide variety of bets on the World Series.

    You also don’t need to be a Nevada resident to play online in the state. You just need to be physically located within state lines. So you could stay in a Vegas hotel and bet on the World Series without ever leaving your room.

    However, you do need to register in-person at the sportsbook of choice before you can bet online. For convenience, Caesars Sportsbook is the most prominent retail sports betting brand, so it’s likely in the hotel you’re staying at or very close by.

    How World Series Bettings Odds Are Calculated

    When you bet on the World Series in the US, you’ll likely be dealing with American Odds.

    Simple Overview Of American Odds

    Basically, the plus (+) number is how much you’ll win if you bet $100. The minus (-) number is how much you need to bet to win $100.

    The more likely the bet is to be successful, the higher the minus number (and the lower the payout). The more unlikely a bet, the larger the plus number (and the higher the payout).

    For example, let’s say the Houston Astros play the LA Dodgers in the 2021 World Series. For Game 1, the straight bet moneyline might be:

    Astros +150

    Dodgers -125

    If you bet $100 on the Astros and they win the game, you’d win $150 and receive $250 ($100 wager plus the $150 in winnings).

    If you bet $100 on the Los Angeles Dodgers, you’d win $80 and receive $180 (your wager plus winnings). But if you were to bet $125 on the Dodgers and they won, you’d win $125 and receive $225.

    To manually calculate win potential for minus odds, you divide 100 by the number, then multiply the decimal by your bet. For the Dodgers line above, that would be 100/125 = 0.80, then 0.80 x $100 = $80.

    For the plus odds, you’d divide the odds by 100. In the Yankees example, that would be 150/100 = 1.50, then 1.50 x $100 = $150.

    You could also just use an online calculator. And most online sportsbooks will let you click the bet and type in any amount to see what the payout would be.

    Off-Season Betting Odds For The World Series Breakdown

    LA Dodgers

    Oddsmakers across virtually every legal sportsbook had the Los Angeles Dodgers in place as the favorite to win the 2021 World Series.

    The Dodgers expected to return a core of All-Stars, including former MVP Mookie Betts, Cody Bellinger, Max Muncy, and Corey Seager on offense. Pitching greats like Clayton Kershaw, Trevor Bauer, and Walker Buehler were also on the team, which produced a league-best 43-17 regular-season record in 2020.

    New York Yankees

    The Yankees made their MLB-record 56th postseason appearance in 2020, going 33-27 and finishing 2nd in the AL East. New York advanced to the American League Division Series but lost to the Tampa Bay Rays in five games.

    The Yankees pitching staff, anchored by All-Star Gerrit Cole, was expected to return as an improved unit for 2021, as the Yankees often spend whatever money is necessary to bolster the roster in the offseason. New York’s powerful batting lineup, which was projected to bring back Aaron Judge, Luke Voit, and DJ LeMahieu, stood as one of MLB’s most intimidating offensive forces.

    Atlanta Braves

    The Braves held a three-games-to-one lead on the Dodgers in the 2020 National League Championship Series. The team saw its chances at a World Series appearance thwarted, however, as Los Angeles came back for three consecutive wins to clinch an improbable comeback.

    Atlanta returned to the 2021 season as a strong contender for a championship in the eyes of legal sportsbooks. Pitching ace Max Fried came back as the centerpiece of the Braves’ starting rotation as well.

    Atlanta’s batting order includes offensive powerhouses like Freddie Freeman, Marcell Ozuna, and Adam Duvall. After finishing first in the NL East in 2020, the Braves looked poised for a return to the postseason in 2021.

    San Diego Padres

    Perhaps the biggest surprise of the 2020 season, the San Diego Padres produced the second-best record in the National League. San Diego’s 37-23 regular-season finish trailed only the Dodgers for the best record in the NL.

    The Padres made it to the playoffs for the first time since 2006, but a three-game sweep at the hands of the Dodgers ended the Padres season in the National League Division series.

    The team returned with the core of its power-hitting lineup for 2021, including Fernando Tatis Jr., Manny Machado, and Wil Myers.

    Tampa Bay Rays

    The Tampa Rays came up short of a World Series title, losing four games to two against the Dodgers in the final playoff battle of 2020. The roster in place might make the Rays a title contender for years to come, however.

    The Rays 40-20 regular-season record stood as the top mark in the American League. Offensive stars Brandon Loew and Randy Arozarena return to anchor the Rays lineup, with Arozarena coming off a record-setting 2020 postseason.

    Starting pitchers Blake Snell and Tyler Glasnow form the core of a starting rotation to make the Rays strong contenders to return to the postseason in 2021.

    MLB World Series Odds and Betting

    Because baseball is such a popular sport in the US and worldwide, most MLB games have a good number of choices for betting. But the World Series brings the largest number of options, more than any other time of year.

    MLB Moneyline Bets

    The moneyline bet is also called a straight bet, and it’s the simplest bet you can make. Before the game begins, you bet on which team will win, and the number of runs doesn’t matter.

    Run Line (Points Spread) Bets

    In a run line, the number of runs does matter. You can either pick the underdog to win by any amount or lose within a specified number of runs, or you pick the favorite to win by a specified number of runs.

    Series Bets

    Rather than bet the moneyline on a single game, you can bet it on the series. This is a particularly hot bet when it’s the playoffs, and the World Series is the most popular Series Bet at the sportsbook.

    MLB Totals (Over/Under Bets)

    Rather than betting on a team or player, you can simply bet on the total number of runs scored by both teams combined. The sportsbook will set an amount, and you can bet that it will be over or under the bookmaker’s guess.

    MLB Parlay Betting

    A parlay is where you make multiple bets and receive a payout only if all bets are correct. Bettors choose to parlay to increase the overall winning potential.

    What Is An MLB Futures Bet?

    An MLB futures bet is placing a wager on a future event. Most commonly, this is who will win the NL and AL pennants as well as the World Series.

    A futures bet can only be placed in advance. The more teams that are eliminated, the fewer the potential winners, and the fewer futures bets the sportsbook will take.

    Bettors who have a good feeling about a specific team to win it all are best suited to place their futures bet early. If the lead-up to the playoffs has that team doing better and better, the odds will shift in the team’s favor, and the potential payout diminishes. The opposite is true for an early favorite. And therein lies the strategy for futures betting.

    What Is A World Series Prop Bet?

    A prop bet is a wager on an in-game outcome or a futures bet on a specific player.

    For the World Series, this will include things like Over/Under bets on the first five innings, who will get a hit, and so on. Prop bets can vary dramatically between betting sites.

    Prop bets from the 2020 World Series included interesting wagers like this parlay that USA Today sports betting expert “Johnny Parlay” booked for Game 2 and Game 6 on BetMGM.

    The Game 2 bet set +425 odds on Tampa Bay’s Snell recording four or more strikeouts and the Dodgers’ Seager hitting a home run. The parlay paid off in Game 2, prompting the writer to make the same bet again for Snell’s next start in Game 6.

    Snell struck out nine in Game 6, but Seager didn’t hit a home run.

    MLB Prop Bets

    MLB games in general will usually feature prop bets. You can bet on whether a batter will get a certain number of hits, a pitcher’s strikeouts, and who will hit a home run.

    You can also place player prop bets on a future outcome. Examples include the Cy Young winner and Rookie of the Year.

    At the end of the day, prop betting is only limited by what the sportsbook is willing to take bets on. You can also request that a sportsbook will create a line for you if you want to place an unlisted prop bet.

    Betting Odds For The World Series FAQ

    Is it legal to bet on the World Series in the US?

    Yes, depending on where you’re located. Sports betting is legal in about two dozen states, although at different levels of acceptance. States like Colorado, Arizona, Michigan, and New Jersey are some of the easiest states to bet on the World Series.

    How old do I need to be to bet on the World Series?

    21. In most states, you need to be at least 21 years old to bet on the World Series. This applies to online and physical sportsbooks.

    However, there are some exceptions. In Rhode Island, New Hampshire, Washington, D.C., and Oregon, the legal age is 18 and up because one of the online sportsbooks is run by the state lottery. Further, you can bet in-person if you’re 18 and up at some tribal sportsbooks in Michigan, New York, and elsewhere.

    In most states, you can play Daily Fantasy Sports (DFS) if you’re 18 and up. All major DFS sites will have World Series events where you can win real money.

    Where can I bet on the World Series?

    If you’re in a state where online sports betting is legal, you should have a few high-quality options for placing bets. The sites and apps with the best odds, promotions, and customer service include:

    • DraftKings
    • BetMGM
    • Caesars
    • BetRivers
    • FanDuel

    The list goes on. The great thing about betting at a legal site is that you know you’re joining a legitimate sportsbook that will pay out promptly and feature fair terms and conditions. The same can’t be said for illegal sites.

    Is it safe to place a World Series bet online?

    Yes, if you bet at a legitimate and trusted online sportsbook site or app. However, if you live outside of a state where online sports betting is legal, placing a bet online can be unsafe.

    Offshore sites that accept all US players no matter what state are breaking the law and people who bet at them technically are as well. While you likely won’t be prosecuted for placing a bet, you have no recourse if the site refuses to pay or hits you with unfair terms and conditions.

    Do online sportsbooks offer in-game, live betting during the World Series?

    Yes. At legal online sportsbooks in the US, in-game betting (also known as live betting) is legal. That means you can place bets after the game begins, and place bets over the course of the game.

    If you’re not able to bet at an online sportsbook, you’ll have to visit the physical sportsbook to place in-game bets. Otherwise, your only option is placing pre-game bets.

    Who is the current favorite to win the World Series in 2021?

    Los Angeles Dodgers. At most sportsbooks, the Dodgers are the frontrunner to win the 2021 World Series. The Houston Astros, Boston Red Sox, and Atlanta Braves are the next most likely to win, respectively.

    Will there be a World Series in 2021?

    Yes. The 2021 World Series will start on Tuesday, October 26. It will take place after a 162-game regular season and a return to the traditional 10-team playoff format.
