• bet365 announced it would honor all 49ers Jordan Mason props at their original odds
• The sports betting operator attempted to alter odds on Mason props after bets accepted
• The operator said bets were placed on an event with “incorrect odds”

Sports betting operator bet365 has decided to honor the original odds of prop bets placed on 49ers running back Jordan Mason’s rushing yardage total after customers expressed displeasure that the operator attempted to alter odds on already placed bets after star San Francisco running back Christian McCaffrey had been ruled out of the game.

A number of bet365 customers expressed concern Monday after receiving a notification from bet365 that prop bets placed on Mason’s yardage were “placed at incorrect odds” and altered in accordance with house rules.

Customers who placed bets on the over(-110) for Mason’s yardage total, which was set at 13.5 yards for the 49ers tilt against the Jets, saw their odds revised to -5000 by the operator after it was announced star running back McCaffrey had been ruled out of the game.

Customer Express Concern Over Alterations

Customers flocked to social media prior to the start of Monday Night Football to express their displeasure with bet365 notifying them that it would not be honoring the originally advertised odds for bets placed on the over for total Mason rushing yards. The notifications were sent to customers after McCaffrey had been ruled out for the game, which meant Mason would see the bulk of the rushing attempts and likely eclipse the originally set over/under of 13.5 rushing yards.

The notifications read as such:

“We are contacting you regarding bet ID (#) placed at the odds of -110 on Jordan Mason – Over 13.5 (player rushing yards NY Jets @ SF 49ers). We have identified that this selection was placed at incorrect odds and as such, in accordance with our rules, will be settled at the revised odds of -5000. Please accept our apologies for any inconvenience caused.”

A winning $20 bet at the original -110 odds would have paid out $38.18. However, a winning $20 bet at the revised -5000 odds would have only paid out $20.40.

Today, bet365 notified customers on its social media feed that all of the originally placed bets on Mason would be honored at their original odds.

A spokesperson for bet365 did not return a request for comment.

Despite the odds alteration, this is not the first instance of bet365 revising odds of already placed bets for customers due to “incorrect errors.”

NJ Previously Fined bet365 For Similar Instance

Earlier this year, the New Jersey Division of Gaming Enforcement required bet365 pay out more than $519,000 to 199 New Jersey sports betting customers after it was found the sports betting operator revised odds to already concluded bets due that were placed with “obvious errors.”

New Jersey stands out as one of the few states in the country that typically requires operators to honor all bets taken at any odds, even if they’re offered with “obvious errors.”

During a routine audit conducted by the DGE in April 2022, it was determined that bet365 “unilaterally revised odds for a significant number of wagers over an extended period of time” without division approval. The DGE ordered bet365 pay out a total of $519,323.32 to 199 user accounts.

In the vast majority of incidents, the winning bets had already been paid out to New Jersey customers.

The incorrect odds were offered for 13 sporting events from December 2020 through November 2022. The event with the highest amount of bets taken was a Nov. 17, 2021, NCAA basketball game between BYU and Oregon. The operator accepted 63 bets from 18 customers, of which 59 bets won. The operator revised the odds for all winning wagers on the event after being paid out.

The rest of the bets and incorrect markets can be viewed here.

Even though bet365’s approved New Jersey house rules state the operator is allowed to revise odds for an event if posted with an “obvious error,” the DGE says it can only do so with its approval first.

“bet365 failed, in all instances, to recognize that although bet365’s House Rules were approved by the Division, it was with an express statement and caveat that bet365 was prohibited from voiding any wager without prior Division approval, as is the standard course in Division approval of House Rules and as set forth in Division regulation N.J.A.C. 13:69N-1.11(d),”  DGE Interim Director Mary Jo Flaherty wrote in a letter to bet365.
