KSA Warns ZEbetting and Betca Over Illegal Tennis Bets

The Kansspelautoriteit (KSA), the Netherlands' gambling regulatory authority, has issued formal warnings to two licensed online betting providers, ZEbetting and Betca, after identifying illegal betting markets offered on their platforms. Specifically, the operators were found to be offering bets on the outcome of individual sets in tennis matches, a form of wagering that is expressly prohibited under Dutch gambling law.

The enforcement action highlights the Dutch regulator’s ongoing commitment to maintaining integrity in the gambling market and protecting consumers from practices deemed particularly vulnerable to manipulation or abuse.

Prohibited bets and the legal framework in the Netherlands

Under Dutch gambling legislation, it is illegal to offer bets on outcomes that regulators consider negative in nature or easily manipulated. This includes wagers on highly specific or segmented components of a sporting event, such as who will win or lose a single set in a tennis match.

The rationale behind this prohibition is grounded in the prevention of match-fixing and manipulation. Individual set outcomes in tennis, compared to entire match results, are perceived as more susceptible to interference by players or external parties. Betting markets focused on such micro-events increase the incentive and feasibility for individuals to attempt manipulation for financial gain.

Dutch authorities have consistently taken the position that sports betting should be limited to outcomes that are not easily influenced and are part of the broader context of a match or tournament. As a result, betting providers must avoid offering markets that isolate specific moments in a game unless those are permitted under clearly defined regulatory guidelines.

Operators take immediate corrective action

Following the KSA’s intervention, both ZEbetting and Betca cooperated fully with the regulator and acted promptly to remove the prohibited betting markets from their platforms. In their responses, the operators acknowledged the oversight and committed to enhanced internal monitoring mechanisms to prevent similar issues from arising in the future.

The regulator confirmed that both companies had taken “corrective and preventative measures,” which include improving compliance monitoring systems, retraining staff responsible for market selection, and establishing procedures to identify and eliminate unauthorized bet types.

Moreover, both operators pledged to notify the KSA immediately in the event of any future unintentional offering of restricted markets.

Increased regulatory activity signals stricter enforcement era

This warning forms part of a wider regulatory trend in the Netherlands, with the KSA stepping up its enforcement activities amid increasing scrutiny of the licensed gambling sector. In recent weeks, the authority has taken action on several fronts to ensure strict adherence to legal obligations by gambling operators.

Notably, in early July 2025, the KSA imposed conditional fines on three gambling companies found to be advertising unlicensed gambling services via the affiliate website CasinoScout.nl. Each company faces a recurring weekly penalty of €75,000 (approximately $88,000), payable until full compliance is demonstrated.

These actions reinforce the message that the KSA intends to uphold the law vigorously and hold operators accountable for any deviation from legal or ethical standards, regardless of whether such violations are deliberate or accidental.

Ban on sports sponsorships by gambling firms now fully in force

Another major milestone in the Dutch gambling regulatory landscape was the full implementation of the nationwide ban on sports sponsorships by gambling companies, which took effect on 1 July 2025.

According to a recent KSA report, initial data indicates a high degree of compliance with the new regulation. Almost all visible public sponsorships by gambling operators — including branding on jerseys, stadium signage, and event naming rights — have now been discontinued.

The sponsorship ban is part of a broader policy objective to reduce gambling exposure, particularly among minors and vulnerable individuals. Dutch lawmakers have argued that the normalization of gambling through sports partnerships poses long-term societal risks and can contribute to increased problem gambling.

Regulatory context and public interest considerations

The Dutch Remote Gambling Act (KOA), which came into effect in 2021, provides the legal framework under which online gambling is regulated in the Netherlands. It permits licensed operators to offer online sports betting, casino games, and poker, subject to strict conditions designed to protect consumers and ensure market integrity.

One of the key elements of the KOA is its emphasis on preventing gambling-related harm. This includes not only enforcing restrictions on marketing and advertising but also ensuring that operators do not facilitate betting activity that might foster match-fixing, corruption, or addiction.

The KSA's dual role as both a licensing body and an enforcement agency places it at the center of efforts to maintain a safe and transparent gambling environment. Its recent actions — including the warnings to ZEbetting and Betca — reflect an increasingly proactive regulatory stance.

ZEbetting and Betca’s market presence and reputation

ZEbetting and Betca are both authorized gambling operators within the Dutch regulated market. They operate under licenses granted by the KSA and are subject to continuous oversight and periodic audits.

While the recent warnings may reflect lapses in internal controls, both companies are believed to have acted in good faith upon discovery of the prohibited markets. No financial penalties were issued in connection with this particular enforcement action, and no formal sanctions have been announced.

By responding swiftly and transparently to the KSA’s findings, ZEbetting and Betca appear to have avoided more severe consequences, such as license suspension or fines.

Industry implications of increased scrutiny

The enforcement against ZEbetting and Betca serves as a cautionary tale for all licensed operators within the Dutch market. As regulatory expectations become increasingly stringent, operators must invest more heavily in compliance infrastructure and employee training to remain in line with evolving requirements.

The Dutch market remains one of the most tightly regulated gambling environments in Europe, and the risk of reputational and financial damage for non-compliance is significant. In addition to financial penalties, companies found to be violating Dutch gambling laws face heightened scrutiny, loss of consumer trust, and, in extreme cases, revocation of licenses.

As such, a robust compliance framework is no longer optional but a strategic necessity for companies operating in the sector.

Looking ahead

With the gambling sector undergoing rapid transformation, the regulatory environment in the Netherlands is likely to evolve further in the coming years. Areas of anticipated focus include:

• Increased automation of compliance monitoring using artificial intelligence
• Tighter restrictions on gambling advertising and promotions
• Stricter rules around consumer data protection and responsible gambling
• Broader regional cooperation across the EU to combat illegal gambling and match-fixing

Operators will need to remain agile and well-informed, ensuring that their internal systems are capable of adapting to regulatory shifts with minimal disruption. The KSA has repeatedly emphasized that ignorance of the law is not a defense, and that even unintentional breaches will be met with formal enforcement action.

The message from the regulator is clear: compliance is a continuous process, not a one-time box-checking exercise.

Conclusion

The formal warnings issued by the Dutch Gambling Authority (KSA) to ZEbetting and Betca mark yet another firm step in the Netherlands’ ongoing effort to uphold the integrity of its regulated gambling market. By addressing the offering of prohibited tennis set bets — which are considered particularly vulnerable to manipulation — the KSA has reinforced its commitment to consumer protection, transparency, and lawful betting practices.

Although both operators responded swiftly and cooperatively, the incident serves as a cautionary reminder to all licensed providers operating in the Dutch market. With increasingly active regulatory oversight, companies cannot afford lapses in compliance — even unintentional ones — without risking reputational and legal consequences.

The broader context of this enforcement action reflects a regulatory environment that is becoming more assertive and proactive. From stricter restrictions on advertising and sponsorships to penalties for promoting unlicensed services, the KSA continues to set clear expectations for the industry. For gambling operators, the path forward demands rigorous internal controls, ongoing staff training, real-time monitoring systems, and above all, a culture of compliance.

As the Dutch market evolves, so too must the practices of those who participate in it. ZEbetting and Betca’s experience illustrates that early correction and full cooperation can mitigate damage — but prevention remains the best strategy. In a jurisdiction as tightly regulated as the Netherlands, operational vigilance is not merely good business; it is an essential legal obligation.
