New Jersey online gambling generated $11.7 million in revenue for the month of June, a sizable increase in year over year numbers.

The figure represents a substantial jump in online gaming revenue from June 2014, according to the monthly report prepared by New Jersey’s Division of Gaming Enforcement.

New Jersey virtual casinos posted revenues of $9.5 million last June, meaning there was an increase of nearly 23 percent, year over year.

Although online gaming revenue remains a fraction of New Jersey’s total gaming income — $217 million last month — the June report is encouraging, and validating, for proponents of the technology who have long maintained that virtual casinos would continue to build steam in the state.

While gaming revenue has fallen overall compared to last June’s receipts, the success of the online market marks a silver lining for New Jersey gaming.

NJ Online poker revenue falls, despite overall online growth

The online industry grew despite a decline of approximately 10 percent in online poker revenue, compared to June of last year.

In June 2014, poker games accounted for 21 percent of online revenue, a figure which declined to 16 percent in June 2015.

The dip in online poker receipts, however, was offset by a continued growth of the online casino market. New Jersey casinos collectively reported a 32 percent increase in online casino revenue from June 2014.

June 2015 revenue rankings

Here is a look at the revenue taken in by each casino and online operator pairing for the month:

• Borgata and PartyPoker: $3.547 million

• Caesars / Harrah’s and 888: $2.635 million

• Tropicana and Virgin: $2.561 million

• Golden Nugget and Betfair: $2.525 million

Borgata and PartyPoker NJ continue to lead

Holding onto its spots atop the online market is the Borgata, with its online partner PartyPoker. The duo has led New Jersey online casinos in revenue in each month since regulated online gaming began in late 2013.

Approaching a total of $72 million in online revenue since 2013, Borgata and PartyPoker stand comfortably atop the market, having raked in over $20 million more than second-place competitor Golden Nugget and its online partner Betfair, and $31 million more than third-place Caesars/Harrah’s and partner 888.

And it appears the gap is widening. In June, Borgata and PartyPoker posted revenue of $3.55 million, outpacing the month’s second-place finisher Caesars by nearly 30 percent.

Rest of the pack posts nearly identical revenues

But despite the advantage currently held by Borgata and PartyPoker, competition among the online casinos in the state is fierce.

The three remaining major players — Caesars, Tropicana, and Golden Nugget — all posted revenues within $100,000 of one another.

Remaining neck-and-neck with Caesars is an impressive achievement for both the Tropicana and Golden Nugget casinos, which feature casino games only and do not offer online poker.
