After years of growth, the latest figures show a clear reversal. Total gross gaming revenue, or GGR, fell to EUR 1.61 billion in 2024, down from nearly EUR 1.69 billion in 2023. According to industry reporting based on the newly released Belgian Gaming Commission data, that is the first full-year decline since the pandemic period.

That matters for two reasons.

First, it confirms that stricter regulation is now hitting the legal market in measurable financial terms. Second, it raises a harder question: if the regulated market is shrinking while illegal operators remain easy to access, is Belgium actually improving player protection, or just weakening the legal offer that is supposed to keep players inside a controlled system?

The headline number is clear enough. The legal market is smaller than it was a year earlier. But the detail is even more important. Online gambling still represented the majority of Belgian GGR in 2024, with roughly 57% of the market, while land-based gambling accounted for 43%. Even so, online was no longer growing. Reporting on the new figures says online GGR slipped 2.70%, while the land-based segment dropped by nearly 8%. That means the downturn was broad, not limited to one corner of the market.

In other words, 2024 was not just a weak year for physical venues. It was also the year when online stopped acting as an automatic growth engine.

That shift did not happen in a vacuum. Belgium tightened several gambling rules in 2024. The amended law that took effect on 1 September 2024 raised the minimum age to 21, introduced a ban on gifts, bonuses and free games, and reinforced a general principle of advertising restrictions. The Commission also confirmed that the same player account can no longer be used across different licensed gambling activities.

Those changes were sold as stronger player protection. That is the official logic, and part of it is easy to defend. Tighter age rules and less aggressive promotion are obvious ways to reduce exposure, especially among younger and more vulnerable players. But regulation is only one side of the equation. The other side is channelization: keeping players on legal, monitored platforms instead of pushing them toward offshore sites that ignore Belgian rules.

This is where the 2024 picture becomes more worrying.

One of the most striking warnings in the Belgian Gaming Commission’s 2024 Annual Report is not about a legal operator at all. It is about the illegal market. The report states that, through third parties, financial transactions between Belgian banks and illegal gambling sites remain possible, which can increase player trust in those operators even though they are outside the legal framework.

That is not a theoretical concern. In 2024, the Commission says it sent 61 reports to the Public Prosecutor for illegal gambling offers in Belgium, and 105 URLs were added to the blacklist.

So the risk is not simply that the legal market went down. The real risk is that part of that lost activity does not disappear. It may migrate.

The B+ segment is one reason that risk deserves attention. Early reporting on the newly released financial data highlights a 23.83% drop in the B+ segment in 2024. In Belgium, B+ licences are the online extensions linked to class B gaming arcades.

That is a major fall, and it should not be treated as a side note. A contraction of that size suggests that some of the regulated offer was hit much harder than the market average. If a legal segment loses close to a quarter of its financial activity in one year while illegal sites remain reachable, the policy question becomes unavoidable: are players being redirected to safer gambling, or to less regulated gambling?

The enforcement picture does not fully reassure.

The Annual Report says the Commission imposed 66 fines in 2024, including 8 with full or partial suspension, for a total of EUR 4,605,700. But on that amount, only EUR 27,525 was actually collected.

That gap is too large to ignore. On paper, sanctions look tough. In practice, the recovery rate is extremely low. For a sector where illegal supply, cross-border access and fast domain changes are constant problems, weak collection limits the deterrent effect.

The result is a 2024 market story that is more complex.

Yes, the legal Belgian gambling market went down. Yes, stricter rules likely played a role. And yes, a drop in gambling revenue is not automatically bad news if it reflects lower exposure among at-risk players. But that is not the full picture. The Commission’s own reporting shows continued pressure from illegal operators, continued blacklist activity, and continued gaps in enforcement and payment blocking.

That is why the most important takeaway from Belgium’s 2024 gambling data is not just that the market shrank by roughly 5%.

It is that Belgium is entering a more fragile phase. The legal market is no longer expanding. Online is no longer masking weakness elsewhere. One licensed segment appears to have fallen sharply. Meanwhile, illegal sites remain active enough for the regulator itself to warn that players can still transact with them.

If Belgium wants stronger player protection, the next step cannot be regulation alone.

It also needs better channelization, faster blocking, stronger payment enforcement, and a legal market that remains attractive enough to keep players away from operators who offer no Belgian safeguards at all. Otherwise, a shrinking legal market will not mean less gambling. It may simply mean less regulated gambling.
