The 68th Daytona 500 kicks off this Sunday. As NASCAR’s top drivers prepare to tackle 500 miles of racing, BetRivers is giving new bettors a head start. Make the Daytona 500 your first bet, and if it loses, BetRivers will give you a second-chance bet worth up to $500. Here’s how to claim the bonus.   BetRivers Sportsbook NASCAR Promo: Enjoy a $500 safety net on your first Daytona 500 bet.   The 68th Daytona 500 begins this weekend to mark the start of the 2026 NASCAR Cup Series. With engines at work in Florida, defend your bankroll with the BetRivers welcome offer. To enter, all you have to do is bet on your favorite contender at the Daytona 500. BetRivers bonus code will provide you with a Second-Chance Bet up to $500 in case you lose.  This way, the initial stake is returned in bonus bets and literally gives you two shots at success. Please note that bonus bets function differently from cash. A win with your sportsbook bonuses only gives you the net winnings; you can’t cash out the bonus money itself. For instance, when you bet $100 on one of the favorites, such as Joey Logano, at +1200 odds. If you win, you would get a profit of $1,200 plus the initial $100 which you bet. This means you would receive a total payout of $1,300. If the bet loses, you become eligible for the Second-Chance Bet under BetRivers’ welcome promotion. You will get your $100 back in the form of a Second-Chance Bet. It would allow you another opportunity to play later in the season.   Steps to get up to $500 back as a Second Chance Bet on BetRivers. Get started by accessing the BetRivers platform via web or sportsbook app. Then follow the steps outlined here: > Begin registration by providing your information and passing an identity check. > Apply the specific BetRivers promo code (SPORTS) at sign-up to ensure your account is eligible for this offer. > Select a suitable payment option and fund your account with at least $10. > Enter the race weekend by placing a qualifying bet of up to $500 on this tournament. Don’t worry if your pick falls short; BetRivers will provide a full refund of your stake, up to $500.   BetRivers Sportsbook Additional Promo Terms and Conditions.

This Sunday marks the start of the 68th Daytona 500, the 2026 NASCAR Cup Series. The 500-mile showdown at Daytona International Speedway is known for defining careers.  Much of the attention will center on two-time defending champion William Byron (No. 24 Chevrolet). Byron will attempt to secure a historic third consecutive Daytona 500 victory, an achievement never accomplished in the event’s history. Legends such as Richard Petty and Cale Yarborough have won back-to-back editions, but no driver has ever captured three in a row. Kyle Busch is another driver to watch. Rowdy comes into this contest in search of his first Daytona 500 win. However, he remains a seasoned driver with over 60 career wins and two championship titles. After earning pole position on Wednesday, “Rowdy” now starts from the front with a strong chance to end his 21-year wait for a win in this race. After betting on the race, watch the live coverage of the Daytona 500 on Fubo or FOX Sports, which begins as early as 2:30 ET.   Comparing Other Sportsbooks’ Offers for the NASCAR Daytona 500 In case BetRivers does not provide you with the protection you need, the following are the current best offers among the US sportsbooks: > Caesars Sportsbook: Register and receive a 100% bet match on your initial bet, limited to $250. > FanDuel: New customers who win their first bet with their initial bet of $5 are eligible to have an extra $100 bonus. > Bet365: Win a bonus bet of $150 when you deposit and bet 5.
