1/ST BET promo code breakdown: use 500BET

With the 1/ST BET promo code 500BET, new users receive $20 in wagering credits for every $100 wagered on the app. The maximum total for this offer is $500 in wagering credits, which would require a new user to wager $2,500. 

New 1/ST BET members have 60 days to obtain wagering credits through this 1/ST BET promo, and these bonuses are credited within 72 hours of $100 worth of wagers settling. Wagering credits expire after 14 days. It's also important to note that if you win a bet using wagering credits, you receive the winnings and not the stake. For example, if you wagered $20 in wagering credits on a horse at 5/1 odds and it won, you'd receive $100, but you would not get that $20 stake back. 

This offer is only available to new 1/ST BET users who are of legal age in a state where 1/ST BET is available. Get started here:

All three were trained by Cox, who won the 2021 Kentucky Derby with Mandaloun after Medina Spirt was disqualified for a failed drug test. The latest 2026 Kentucky Derby odds list Commandment at 6-1 while Further Ado was priced at 5-1 on the morning line and Fulleffort was rated as an 20-1 longshot.
