How online casino operators are taking over the sports world - one sponsorship at a time
Jun 27, 2025, 5:15AM
From football fields to tennis courts, the gambling industry is putting a big stake on sports partnerships.
If you've watched a pro tennis match lately and thought, "That's a strange logo on the umpire chair," you're not seeing things. It's not your imagination, online casinos are popping up everywhere in sports nowadays. From tacky courtside ads to jersey logos, the gaming world is leaving its imprint in the world of pro sports. So, what's the story?
Serving aces… and ads: The rise of online casino sponsorships
Whether you’re tuning in for Wimbledon or watching the ATP Tour from your couch, you’ve probably noticed a surge in unfamiliar names sponsoring tennis events and other sports events. Many of those names aren’t tech companies or sports brands, they’re online casinos.
No surprise. Online gambling companies have been going after sports sponsorships as a way of reaching broader audiences, legitimizing their websites and connecting with an unbelievably targeted demographic. Tennis, with its global following and round-the-clock action, has become a favorite playground for these kinds of operators. And it is not only European. From the US to Australia, and all locations in between, online gambling companies and Bitcoin casinos USA are becoming creative in how they insert themselves into the sports environment.
Why tennis? The match made in betting heaven
Tennis has long been a favorite of sports bettors, thanks to its fast pace and year-round calendar, as well as the variety of betting markets (who knew double faults were a betting proposition?). That has made it fertile ground for online casinos seeking to encourage brand awareness and sign up bettors.
Events like the US Open, Roland Garros and smaller ATP 250 tournaments have all seen a rise in gambling sponsors. Some tournaments have even gone so far as to name courts or build custom branded fan zones, complete with games, giveaways and QR codes that link directly to gambling sites.
For online casinos, tennis presents a gilt-edged opportunity: An adult-skewed fan base with disposable income, a never-ending supply of matches upon which to bet and relatively clean branding real estate compared to more commercialized sports like soccer or basketball.
From the court to the casino: How the money flows
Sponsorship arrangements exist in all forms and sizes, yet the goal is usually the same: Visibility and credibility. Operators of online casinos shell out big money to have their logos plastered on banners, player uniforms or tournament merchandise. What they get in return are eyeballs from millions of fans who view live or on-demand.
Others go a step further, even sponsoring athletes on an individual level. These deals include social media appearances with branding, promotional appearances and even bonuses based on performance.
And then there are the comparison sites: Sites that assist users in locating the top online casinos based on what they are searching for. These websites frequently have a large part to play in the sponsorship jigsaw. One type of website that is increasingly popular is the Bitcoin casinos for individuals wishing to use cryptocurrency to gamble. The sites list top-rated casino providers, frequently spotlighting those offering the biggest bonuses, quickest payouts and best sports partnerships.
The elephant in the room: Ethics and integrity
For as much as the marriage of sport and gambling makes financial sense, it is not without controversy. Critics think that the volume of online casino revenue entering sport encourages a dangerous normalization of gambling, especially among young fans.
Tennis has already had its fair share of match-fixing scandals, and some worry that this rush of gambling sponsorships has the ability to further muddy the waters. When the same company taking your bets is also sponsoring the tournament, it raises unavoidable questions about fairness, transparency and oversight.
Governance bodies like the Tennis Integrity Unit have tried to get ahead of the issue, cracking down on who can sponsor what and being more vigilant. But it's a losing battle when the money is this good, and when so many events rely on that sponsorship to stay in business.
Not just tennis: A global phenomenon
Though tennis is a high priority, online casino sponsorships reach far beyond. European football clubs have been virtually taken over by gambling logos, with West Ham United and Valencia CF signing multi-year deals with casino operators. In the United States, partnerships between sporting leagues and betting sites like DraftKings and FanDuel are now the norm.
Even combat sports feature ring mats and trunks covered in casino logos. The message is obvious: Wherever fans gather, there's a casino willing to sponsor. Tennis, however, is different. It's one of the only international sports with round-the-clock events, individual competitors primed for branding agreements, and a somewhat more "high-end" reputation. That makes it particularly appealing for online casinos seeking to stand out from the pack.
What this means for fans
So, where does that leave the casual tennis fan? Well, it largely depends on how you feel about gambling. If you're comfortable with it, the fact that all of these casino sponsors are coming on board just means more prize money, better fan experiences and bigger tournaments. If you're not, it's a bit like the sport is being sold to the highest bidder.
Either way, this is no passing trend. Online casino companies have wagered the house on sports sponsorship, and tennis is just a small slice of their growing portfolio. As viewers, it's our decision where we want to draw the line between commercial reality and the sport's integrity.
