Delaware punters won more from sports wagers during October, despite spending around $2m (£1.6m/€1.8m) less than in the previous month.
Total sports wagers amounted to $14.7m over the month ended October 28th, down from $16.8m in September.
Delaware Park remained the venue of choice for the majority of players in the US state, with $10.6m bet on sports in October, some way ahead of Dover Downs on $2.2m and Harrington Raceway with $1.9m.
However, despite betting less, punters walked away with greater winnings, with the total amount won by players in October rising to $14.2m.
As a result, net proceeds for casinos in Delaware dropped to just $448,600, the lowest monthly total since the state moved to legalise sports betting after the repeal of PASPA earlier this year.
The net proceeds figure is in stark contrast what casinos enjoyed in September, when they took in $3.2m from $16.8m in bets. The September figures were the highest Delaware has reported in its short history of regulation.
From when Delaware launched its regulated sports betting market on June 5 to the end of October, punters have bet a total of $54.5m on sports wagers in the state.
In contrast, New Jersey, which has also moved to legalise sports betting after the ruling on PASPA, took $184m in September alone. The New Jersey Division of Gaming Enforcement is due to announce its results for October later today (Thursday).
