Pari-mutuel betting is the legal foundation of most regulated gambling on horse racing — and in some states, greyhound and jai alai — across the United States. Governed at both the state and track level, these rules determine how wagers are handled, what bets are accepted, and how winnings are paid out. If you're betting at MyWinners or any US-based platform, understanding these basics is key to avoiding surprises at payout time.


Who Regulates Pari-Mutuel Betting in the US?

There is no federal regulator for horse race betting in the United States. Instead:

  • Each state has its own racing commission or gaming authority.

  • These bodies set the rules for legal wagers, payout structures, and licensing.

  • Licensed operators like MyWinners.com follow these state-level rules strictly.

Examples include:

  • New York State Gaming Commission

  • California Horse Racing Board

  • Connecticut Department of Consumer Protection


Core Rules Every Bettor Should Know

  • Betting closes at post time: Once the race begins, no more wagers can be accepted.

  • All wagers are pooled: This is true of all pari-mutuel betting systems — you’re betting against the pool, not the house.

  • Minimum wager amounts apply: Typically $2 per bet, but lower for some exotic wagers online.

  • Takeout is deducted before payout: Each jurisdiction sets a percentage the operator keeps (usually 15–25%).

  • Winning tickets expire: Depending on state law, you may only have 30 to 365 days to claim your winnings.


Not All Bets Are Accepted

Tracks and online platforms may limit or exclude certain bet types based on race size, betting volume, or platform restrictions. For example:

  • Pick 6 may be disabled for small fields

  • Superfecta bets might not be offered on short races

  • Live bets (after post time) are never allowed


💡 Did You Know? While online betting platforms like MyWinners are legal in multiple US states, you must be physically located in a licensed state when placing a bet. Your device may be subject to geolocation verification to confirm this.
