New Numbers Show US Gambling Sites Seeing Traffic Surge
17 September 2026
Gambling sites in the United States have seen a fresh traffic surge, attracting higher numbers of visitors in recent months. In August 2026, Chumbacasino.com led all gambling websites in the US with an astounding 30.6 million monthly visits, according to data from Semrush. That's enough activity to turn heads in gaming food fights...if food fights required numbers.
The site dominates the traffic, but less than half the traffic it sees reaches it in a desk chair, with 12.63% visits coming from desktop while 87.37% are mobile.
Traffic Snapshot
In August 2026, powerball.com ranked second with 14.99 million visits, also leaning heavily mobile at 87.37% of visits. Close behind was DraftKings at 13.89 million. With its vast player base, mobile gaming hints at that now-ubiquitous push for mobile-first: all the top US gambling sites recorded an overwhelmingly mobile-leaning mix of traffic.
Srengthening seasonally
These new data points come as annual traffic to all gambling sites has been rising, a trend supported by recent reports and network-level data. In February 2025, DNSFilter measured a 71% increase in daily traffic to gambling sites compared to the previous year's same timeframe, underscoring broader growth in engagement with online gambling platforms.
So traffic has risen, probably driven by increased online interest. User behavior data, too, points to a more engaged betting cohort.
However, those behavioral metrics highlight a Nuance. In August 2026, US casino bettor activity rose to 9.0 days, up from 8.6 in July. But as user engagement increased, retention saw a reverse: overall August 2026 US retention fell 6% month-to-date from 71% to 65%, according to an analysis from EGR Intelligence. Globally, retention fell even further, from 73% to 60% during the same period.
The swing towards more usage, less retention has clear consequences for player activity that could prove tricky for legal operators vying to retain a share of the online user base.
It suggests a growing trend of *private online gambling* - think sweepstakes, offshore gambling, and lottery-led traffic, where user experience leans towards shopping. The core indications follow that it's those types of iGaming brands commanding the US traffic surge, while traditional licensed sports-betting companies such as DraftKings also perform strongly.
Baying for new blood
Digging into those *shopping-window* gambling brands highlights a fragmented landscape that points to further growth in 2026.

In the 1H 2026 period, sweepstakes brands accounted for 57.9% of online gambling demand, according to Online Casino Rank. In their evaluation, Chumba Casino leads with 10.9% of US iGaming demand, while LuckyLand Slots and Crown Coins are neck and neck.
By August 2026, however, Crown Coins was the height of big business, listed in a September 2026 rg.org report as the most popular sweepstakes casino. It held a massive 21.99% of US sweepstakes casino search demand in August.
However, user interest in online sweepstakes is swinging away from the highs, according to the same source in September 2026. According to their analysis, US sweepstakes casino traffic peaked at around 550,000 in mid-August 2026—in a trend toward mid 200s thousand range by month's end.
Offshore fever
Offshore sportsbooks are another piece of the US online gambling puzzle, drawing traffic from states in which they are not legally operating. In June 2026, BetOnline.AG pulled in 22.56 million monthly visits and Bovada.LV attracted 17.49 million—making them formidable contenders among the most trafficked gambling sites, according to Semrush.
Looking at the offline focus on US markets as well, the seven legal online casino states generated over $7.09 billion in revenue through July 2026, up 18.3% compared to the previous year, according to PlayUSA's revenue tracking.
Pennsylvania led the pack with $2.2 billion, followed by Michigan with $2.11 billion and New Jersey with $1.87 billion. These figures underscore the significant growth opportunity that lies ahead for online casino operators, despite the challenges posed by the rise of private online gambling options.
Growth opportunity
Looking ahead, the 2026 data trendline runs towards increased traffic, from neighboring sweepstakes, offshore, and legal sportsbooks operating under their own sets of regulations and restrictions. Sweepstakes and offshore sites in particular hold their own in swipe-out revenue, while legal sites provide steady streams of licensed dollars which allow the US to punch above its weight alongside top online casino states abroad.
It's a fragmented growth story without clear leadership, and D&D fans know better than anyone that when no one's in charge, the clear winners are the players themselves.
