NYRA Restricts Computer-Assisted Wagering One Minute Before Post Starting Feb. 5
NYRA will require computer-assisted wagering that exceeds six bets per second to stop one minute to post, aiming to curb late odds volatility and protect retail horseplayers.

The New York Racing Association has moved to curb high-speed automated betting by requiring computer-assisted wagering (CAW) that executes faster than six bets per second to stop one minute to post in most pari-mutuel pools. The change, announced Jan. 30 and effective Feb. 5, expands NYRA’s timing restrictions beyond the win pool and is aimed at reducing late-stage odds volatility and improving the wagering experience for horseplayers.
Beginning Feb. 5, NYRA will require CAW activity to cease at one minute to post in all wagering pools not previously subject to high-speed wagering restrictions. NYRA considers wagering to be CAW activity when that speed exceeds six bets per second. That numerical threshold means any wagers executed at speeds greater than six bets per second will be treated as CAW and cannot be placed after the one-minute cutoff. David O’Rourke, NYRA president and CEO, framed the move as modernization: “This policy reflects the importance of modernizing pari-mutuel wagering to address the technology-driven evolution of high-speed wagering.” He added that “Reducing odds volatility will increase pricing transparency and improve the wagering experience for horseplayers in New York and across the country.”
Operationally, the public messaging reconciles a full stop on CAW-style high-frequency execution with continued access for slower wagers. As Thoroughbred Daily News explained, “CAW players can still bet after the one-minute time limit, but they will be restricted to six bets or fewer during that time frame.” NYRA’s longstanding two-minute-to-post rule for win-pool batch bets, adopted in 2021, will remain in effect; the organization credits that earlier rule with eliminating dramatic late-odds fluctuations in the win pool and building a foundation of data to support broader action.
NYRA also said it will continue to offer Late Pick 5 and Pick 6 as retail-only wagers, and has removed jackpot provisions in its Pick 6 to blunt a longtime vector of CAW-team exploitation. As TDN noted, “As the carryovers build up in jackpot-style wagers, CAW teams often make huge bets into the pools and were often able to take home the bulk of a pool that built up as regular horseplayers were making losing bets that led to the large carryovers.”

The policy follows industry trends: Del Mar and Santa Anita adopted similar win-pool timing limits after NYRA’s 2021 precedent, while tracks without such restrictions, Churchill Downs, Keeneland, Gulfstream Park, have been cited as having “much more common odds swings,” according to economist and horseplayer Dr. Marshall Gramm.
Key enforcement and technical questions remain unanswered: NYRA has not disclosed exactly how it will detect and block wagers exceeding six bets per second in real time, whether account-level sanctions or API rate-limits will be used, or how the policy will be coordinated with advance-deposit wagering partners and simulcast pools. For retail bettors, the practical effect is clearer: fewer sudden late odds crashes, retail-only jackpot-style pools, and a betting window that favors measured, human-paced wagering. The change will test whether a speed cap can rein in automated strategies without unduly disrupting liquidity and the market dynamics that power pari-mutuel racing.
