The best horse racing betting sites may not be where you think. In the United States, state laws separate sportsbooks and racebooks. As such, there are many separate racebook apps with promos currently available. On this page, we will offer an introduction to horse racing betting strategy through a comprehensive horse racing betting guide. That includes the best apps for horse racing online betting, like DK Horse, TwinSpires, FanDuel Racing and 1/ST BET.
Knowing where to bet on the Kentucky Derby online matters because you cannot wager on the big race on sports betting apps. Three of the major horse racing betting sites are FanDuel Racing, TwinSpires and 1/ST BET. Each one offers promos and bonus offers for users new and existing.
Using multiple racing books can allow you to take advantage of each book's offers and promos to try and maximize your returns.
With the DK Horse promo code, the DK Horse sign-up offer includes the $150,000 King of the Track promotion under the Offers tab of the app.
Just opt into the King of the Track promo under the Offers tab, then place a $5+ straight single-horse wager only on the Belmont Stakes winner. If your horse wins, you will split a prize pool of $150,000. The reward is issued via click to claim. So if your horse wins, return to the app and click to claim your prize.
TwinSpires is offering up to $400 in bonus credits for new users. Get a $100 bonus credit for every $400 wagered, with a maximum of $400 in bonus credits available for this welcome offer. No TwinSpires promo code is required. Those interested can click the link in the table above.
After $400 in wagers settle (after races finish and results are official), TwinSpires will add a $100 bonus credit to your account balance. If you wager $800, another $100 will be added for a total of $200 in bonus credits. Bonus credits pay out the same as cash wagers on winning bets. Because of bonuses like this one, TwinSpires has long been an appealing site for horse racing off track betting.
FanDuel Racing is currently offering a bet $5 get $25 in racing bonus. Just click the link in the table above if interested in claiming now. No special FanDuel Racing promo code is required.
For those who may bet on sports with FanDuel, FanDuel Racing is a separate entity that requires creating a separate account.
New users can get up to $500 in bonus bets with 1/ST BET by using the promo code "500BET" when signing up. New users will receive a $20 wagering credit for each $100 wagered on the app in their first 60 days. The maximum in wagering credits that can be accrued is $500, which would require wagering $2,500. The large potential bonus helps make 1/ST BET a highly appealing horse racing betting app.
Prediction markets like Kalshi and Polymarket offer users a way to trade on horse racing outcomes. As federally regulated markets, both are available in most states, appealing to a wide user base. Additionally, both Kalshi and Polymarket offer signup bonuses that are outlined below.
Kalshi's signup promo should appeal to any potential user with an interest in prediction markets. A new user who makes an initial trade of $25 or more receives up to $500 in bonus credits.
Polymarket's offer takes on a more common form. New users who deposit $10 or more receive $20 in trading credits.
