Pennsylvania online and retail sportsbooks posted a record handle of US$342.6m in December — and crossed $1 billion in online bets since launch — to cap a year that generated nearly $1.5bn in wagers.

With a full year of online sports betting ahead and an increasingly robust offering of operators, Pennsylvania could more than double that handle in 2020.

Dustin Gouker, analyst for PlayPennsylvania.com, said: “That last two months of 2019 began to show us the real potential of the Pennsylvania market.

“The launch of DraftKings in November, adding one of the best-known brands to Pennsylvania, helped push online betting forward. And now that the online market is maturing, it is entirely possible that 2020 could bring in $4bn or more in online and retail bets."

In December, Pennsylvania’s sportsbooks accepted $342.6m in wagers, up 8.2 per cent from $316.5m, according to official data. Before November, Pennsylvania had never accepted more than $200 million in a single month.
