Fact Checked

One in 10 Dutch 18-year-olds open a gambling account on their birthday. The regulator knows. Politicians want the age raised to 24. The regulator says that would backfire.

Eleven percent of gambling accounts opened by Dutch 18-year-olds are registered on their exact birthday. Thirty-eight percent open within a month of turning 18. The Dutch Gaming Authority uncovered the pattern in a study of 15,761 newly funded accounts from May 2025. The data is unambiguous. Young adults are waiting for legal age, then signing up immediately. The finding has reignited a political fight. Meryam Sümer, a Christian Democratic Party representative, has called to raise the minimum online gambling age from 18 to 24. Her argument is simple. Reduce temptation, reduce harm. The KSA chairman disagrees. He warned in a February 2025 blog that pushing young adults out of legal channels would drive them to the black market, which minors already access with a few clicks. The tension between protection and prohibition is playing out across three new studies commissioned by the regulator. Together, they paint a detailed picture of how gambling normalises among Dutch youth long before age 18.

The Birthday Effect in Dutch Gambling

The KSA’s control database analysis of May 2025 registrations reveals a sharp concentration. Young adults aged 18 to 24 comprise 33% of all new funded accounts. Within that group, 41% are opened by freshly turned 18-year-olds. The birthday spike is the most Dutch striking finding. One in 10 accounts from 18-year-olds open on the birthday itself. More than one-third open within 30 days. The pattern suggests pent-up demand. Minors encounter gambling through family, friends, and advertising throughout adolescence. They wait for legal eligibility, then act fast. The product mix defies conventional wisdom. Seventy-two percent of young adult accounts start with casino games. Only 11% begin with sports betting. That contradicts the assumption that young men enter gambling through football wagers. Casino games, with their instant Dutch gratification and lower perceived skill barrier, are the gateway. Behaviour in the first quarter shows young adults average four gambling days per month. Their median daily stake is €111, well below the €209 of older adults. Eighteen-year-olds gamble more frequently than 19 to 24-year-olds but with lower individual stakes. The pattern is consistent with exploratory rather than committed play. However, the frequency is what matters for habit formation. Four days per month, sustained over quarters, builds routine.

How Young People Start Gambling

The qualitative study Kansspelreis, conducted by Youngworks and commissioned by ZonMw, interviewed 50 young people aged 16 to 21. The findings trace gambling exposure back to early childhood. Initial contact typically occurs between ages 8 and 12. Christmas scratchcards, family lotteries, and casual betting games at home are the entry points. Most participants did not recognise these activities as gambling at the time. The normalisation begins early and within the family unit. Between ages 12 and 14, independent gambling starts. It is predominantly social. Groups of friends bet together, play poker, or organise football “toto” pools. The social environment fosters acceptance. Gambling becomes what everyone does. The report found that minors routinely circumvent age restrictions. They share online gambling accounts operated by older friends or family members. They pool money through mobile payment apps such as Tikkie. The platforms named are the major licensed operators. TOTO, Bet365, BetCity, and Unibet were all cited. Advertising exposure is constant. TikTok, sports broadcasts, and outdoor venues deliver gambling messages to audiences that include large youth segments. Participants expressed surprise at state lottery advertising on youth-oriented media. The government runs lotteries while proposing to ban private operator ads. That contradiction did not go unnoticed.

Student Gambling Patterns

The second study surveyed 29,724 MBO students, a vocational education cohort, aged 15 to 24 during 2024 to 2026. Thirty-two percent reported gambling in the past year. The breakdown shows 28% of minors and 39% of adults. Most gamble infrequently. Seventy-four percent of minors and 61% of adults gamble once or a few times per year. However, 10% gamble monthly or more. That minority is where risk concentrates. Product preferences shift with age. Minors favour physical outlets. Scratchcards lead at 46%, followed by bingo at 34% and slot machines at 28%. Adults shift toward online. Casino games dominate at 46%, with scratchcards at 35% and sports betting at 32%. Nearly half of minors gamble solely through physical outlets. Young adults increasingly combine physical and online channels. The channel migration is clear. As legal age approaches, online becomes the default. Risk profiles also shift. About half of minors and two-thirds of adults who gamble use high-risk products, defined as casino games, sports betting, and slot machines. Approximately 2% show signs of gambling-related harm. The correlation is with online involvement and multi-product use. Among non-gamblers, 90% have no intention to start. Males report higher intentions to begin than females. The gender gap is consistent with gambling participation patterns globally.

The Age-24 Debate

Sümer’s proposal to raise the minimum online gambling age to 24 came after data showed one in five young people in Enschede is currently in debt. “The key is to reduce temptations,” she said. Her argument links gambling exposure to debt accumulation and advocates tighter regulation as shield. The KSA chairman pushed back in his February blog. He argued that youngsters would be more tempted toward the black market if excluded from legal channels. “We already see minors doing so,” he wrote. “For young people under 21, the illegal supply will still be accessible with a few mouse clicks, while they will no longer be able to enter legal parties, which must adhere to a strict duty of care.” The regulator’s position is pragmatic. Legal operators have age verification, deposit limits, self-exclusion, and responsible gaming obligations. Illegal sites have none. Pushing young adults from the regulated sector to the unregulated one may increase harm, not reduce it. The Dutch cabinet has already proposed a near-total ban on online gambling advertising, with narrow exceptions. KSA chairman René Jansen, speaking in June, called the youth gambling trend concerning. “It is high time to reverse this,” he said. The advertising ban and the age debate are separate tools targeting the same problem. One restricts exposure. The other restricts access. The KSA supports the first. It is sceptical of the second. The studies it commissioned provide the evidence base for whatever policy emerges. The birthday effect is now part of that evidence. It shows that legal age is not just a threshold. It is a trigger.
