October in the United States brings falling leaves, the aroma of pumpkin spice floating through the air, and a hectic time in the sports calendar. The NFL and college football seasons are in full swing. The NBA and NHL seasons are getting underway. College basketball is on the horizon. Last but certainly not least, the MLB season reaches its climax with the World Series taking place.
And even with a lot going on in the betting calendar, World Series betting garners a lot of attention no matter the matchup.
Bet on 2025 World Series Odds at the Top Sports Betting Sites
After the end of the MLB regular season, 12 talented teams will duke it out in the MLB playoffs. The playoffs will culminate with the World Series, a matchup between the AL and NL pennant winners.
Who will be the last two teams standing, and will we see a repeat World Series champion for the first time in two and a half decades? The Los Angeles Dodgers won their first title since 2020 last season and remain the team to beat this season.
There are many great sports betting sites for wagering on the World Series. Along with moneyline betting, run line betting (the baseball equivalent of spread betting), and over/under betting on World Series games, the best betting sites also offer futures odds.
But what are the best World Series betting sites? Below are our five favorite sites.
Best World Series Betting Sites and Sportsbook Promos
BetOnline
For many, BetOnline is considered one of the best online sportsbooks, if not the very best. A big part of why is because of the variety of betting options they offer, including a plethora of MLB prop bets.
For example, you can place World Series futures bets there all year long. Whether you want to bet on the odds after big free agency business has taken place or as the stretch run of the regular season approaches, you can do so at BetOnline.
Are you interested in what BetOnline has to offer? If so, you can get a 50% signup bonus there. With up to $250 in free bets, you can bet on MLB game odds and more.
That bonus also comes with 100 casino free spins, and if you use the code "BNEWS" you will receive an extra $10 cash on top of the 50% bonus and free spins.

BetWhale
BetWhale has odds for every MLB game, and they will have odds for every game in the MLB playoffs and World Series.
Also, while they don't have the selection of futures odds that some other books on this list do, they do have World Series winner odds. And if hedging your bets happens to be needed when a pre-game bet appears to be in trouble, you can place World Series live bets at BetWhale.
What might be the biggest draw when it comes to BetWhale? If you like big bonuses with a reasonable rollover, BetWhale's bonus offers are hard to beat.
On initial deposits, they offer a 125% cash bonus up to $1250, with a 10-time rollover. That means that you deposit $1250, your rollover will be $25000 ($1250 for the deposit + $1250 for the bonus, then multiplied by 10). If you bet on MLB games or other events frequently and win a decent percentage of your wagers, it will not take long to complete that rollover.
On top of that, they offer some of the best reload bonuses—if not the best—in the industry.
They also offer big bonuses for major events, such as the World Series, Super Bowl, NBA Finals, March Madness, Stanley Cup Finals, and more.
Some of the BetWhale bonus codes are advertised on the site. Others are released via email, however. So, if you sign up at BetWhale, check your email regularly to keep up with the latest sportsbook offers from them.
