SuperBook Fined $20K for UFC Betting Error

At the end of August, the New Jersey Division of Gaming Enforcement (DGE) fined Evolution $12,000 for several live casino dealer and croupier rule-breaking problems that took place in 2021 and 2023.

Similarly, in December, William Hill Sportsbook received a $20,000 fine for accepting 42 illegal bets on college basketball after the results came in in 2022 and 2023. The operator then argued that OpenBet, the company responsible for providing the system with games and the times they start on their kiosks and app, was the culprit for the errors. 

Now, the same regulator has slapped the former operator of Westgate Las Vegas’ SuperBook $20,000 over a mistake that affected bets on a 2022 UFC fight.

Computer Glitch Displayed Wrong Odds

SuperBook’s issue involved a computer glitch during the February 12 fight between William Knight and Maxim Grishin. 

According to New Jersey.com, the system incorrectly displayed the odds, showing Grishin at +145 when they should have favored Knight. This caused some winning bets on Grishin to be switched to losing ones.

Former operator SBOpco LLC acknowledged the error but initially did not honor the bets placed at the incorrect odds. As a result, SuperBook customers who correctly picked Grishin as the winner were wrongly denied their payouts. The DGE stepped in and required that the affected bettors be paid.

SBO was responsible for licensing and compliance under New Jersey regulations, not Westgate itself, which means the fine reflects the DGE’s enforcement of those regulations.

This incident came before SBO announced in July 2024 that it would shut down most of its online platforms across the US, including New Jersey, to focus on its operations in Nevada.

Additional Fines

SuperBook faced additional fines for accepting bets on events it wasn’t authorized to offer, including a 2023 college basketball game in Atlantic City featuring a New Jersey team and the NBA All-Star Slam Dunk Contest.

In a separate matter, DGE also fined Digital Gaming Corporation, which shares the same parent company as SuperBook, $112,188. The penalties came after repeated violations of the state’s self-exclusion rules, which let people with gambling problems voluntarily block themselves from wagering.

An enforcement letter dated October 14 detailed that between March 2024 and January 2025, Digital Gaming failed to add self-excluded players to the official state list. This oversight allowed multiple individuals who had opted out to continue gambling online. 

The company also let some players exceed the personal spending limits they had set.“These incidents reflect failures in internal controls and compliance procedures,” wrote Mary Jo Flaherty, interim director of the New Jersey DGE, in the letter.
