Online sports betting (OSB) operators achieved a mere 6.6 percent hold on wagers during December, which had a depressive effect on revenue. Winnings by books plunged 20 percent, even as money wagered rose 12 percent.

Overall, handle was just shy of $2.3 billion, producing winnings for OSB operators of $150.4 million. DraftKings’s share of money bet was down from November, while FanDuel successfully defended its market share.

DraftKings recorded five percent less money wagered, while revenue plummeted 29 percent. Its total handle was $732 million against winnings of $46.5 million.

The largest slice of handle went to FanDuel and its $926 million, an 11 percent jump from December 2023. Revenue, however, slid 25 percent to $70.6 million. Its hold percentage was an above-average 7.6 percent, compared to DraftKings’s 6.4 percent.

BetMGM gained handle share to the tune of 41 percent year over year and Caesars Sportsbook lost some (down 22 percent from late 2023), with BetMGM’s $178 million besting Caesars’s $158 million.

Those numbers translated into revenue of $9.6 million for BetMGM (an 18 percent improvement) and $8.7 million for Caesars, a 45 percent topple. Both books held well below average, Caesars at 5.5 percent and BetMGM at 5.4 percent.

Fanatics saw a 500 percent increase in money wagered, hitting $172 million. At the other end of the spectrum, $7 million was bet with Resorts World, a 35 percent drop-off.

Significantly smaller swings were seen by BetRivers and ESPN Bet: $46 million wagered with the former and $49 million with the latter.

Fanatics bested both BetMGM and Caesars with its $9.8 million in winnings. Despite surpassing BetRivers in betting volume, ESPN Bet made only $1.3 million to BetRivers’s $2.9 million. Resorts World Bet recorded $500,000 in revenue for the month.
