The Scale of Unregulated Gambling in the UK
There is a conversation happening in gambling policy circles that most players never hear. It is not about bonuses or game variety or payout speed. It is about the size, growth and implications of the unlicensed gambling market that operates alongside — and increasingly in competition with — the regulated one. Nine Casino exists within that market, and understanding the market’s dynamics is essential context for any UK player considering an offshore platform.
H2 Gambling Capital tracks £16.6 billion in UK offshore gambling stakes for 2025, with channelisation (the share of gambling on licensed sites) having fallen from 97% in 2019 to 92% in 2025. That gap represents a substantial population operating outside the consumer protections that the UKGC framework provides. These are not exclusively problem gamblers or high-risk individuals. Many are recreational players who migrated offshore in response to specific regulatory changes — stake limits, affordability checks, bonus restrictions — that altered their experience at licensed sites. The migration is driven by preference as much as by vulnerability, but the destination carries risks that apply to everyone regardless of their motivation for arriving there.
Black Market Growth: £5bn to £16.6bn in Six Years
The numbers are striking. The UK’s unlicensed gambling market grew from an estimated £5 billion to £16.6 billion between 2019 and 2025. That is not a gradual drift — it is a tripling in six years, and it coincides precisely with the period of most intensive regulatory reform in the licensed market.
The correlation is not coincidental. Each major regulatory intervention in the licensed market — the £2 FOBT stake cap in 2019, enhanced affordability checks from 2022, the £5 online slot stake cap in April 2025, the increase in Remote Gaming Duty from 21% to 40% — created a friction point that some players responded to by moving offshore. The regulations were designed to reduce harm, and for many players they achieved that goal. But for a subset — those who found the restrictions incompatible with their preferred style of play — the response was not to stop gambling but to relocate it.
The £16.6 billion figure is an estimate, and estimates of illegal markets are inherently imprecise. The methodology typically combines payment transaction analysis, website traffic data, VPN usage statistics and player surveys. Different researchers produce different numbers. But the directional trend is consistent across all credible analyses: the unlicensed market is growing, it is growing faster than the licensed market, and its growth accelerates after each major regulatory tightening.
Nine Casino’s position within this market is one of many Curaçao-licensed platforms competing for UK players who have either chosen to leave the regulated market or who entered online gambling through offshore channels without ever establishing an account at a licensed site. The platform is not a black market outlier — it is a representative participant in a segment that now rivals the licensed market in estimated revenue.
UKGC Enforcement: Site Blocks, URL Removals and Prosecution
The Gambling Commission does not passively accept the offshore market’s growth. Enforcement activity has escalated significantly, working in coordination with the Curaçao Gaming Authority and other jurisdictions to disrupt unlicensed operators targeting UK consumers.
In the 2025-2026 period, the CGA issued 741 cease-and-desist orders against operators making false or misleading licensing claims. Additionally, 1,134 website blocks were coordinated through ISP-level interventions — meaning that UK internet service providers were directed to block access to specific gambling domains identified as operating without appropriate licensing. These blocks are implemented at the DNS level and can be circumvented with VPN usage, but they disrupt casual access and signal regulatory intent.
URL removal requests to search engines represent another enforcement channel. The UKGC works with Google and other search providers to de-index or demote websites that illegally target UK consumers. The effectiveness varies — new domains can replace blocked ones quickly, and the whack-a-mole dynamic means enforcement creates disruption rather than elimination. But the cumulative effect raises the barrier to entry for new unlicensed operators and increases the operational cost for existing ones.
Criminal prosecution remains rare. The Gambling Act 2005 criminalises the provision of gambling services to UK consumers without a UKGC licence, but pursuing offshore operators through criminal channels requires international cooperation and faces jurisdictional obstacles that make prosecution slow and uncertain. The enforcement focus has been on disruption — blocking, de-indexing, cease-and-desist — rather than criminal proceedings, which reflects pragmatic resource allocation rather than lack of regulatory will.
What Black Market Growth Means for Individual Players
The macro-level data matters to policymakers and industry analysts. For individual players, the implications are more personal and more immediate.
First, the growth of the offshore market means more platforms competing for your attention, which drives promotional generosity but also increases the prevalence of poorly managed and outright fraudulent operators. Not every Curaçao-licensed casino operates to the same standard. The reformed LOK framework introduced in December 2024 raised the bar, but enforcement is ongoing and not every operator has fully complied. A growing market attracts both legitimate competitors and opportunists, and distinguishing between them requires due diligence that many players do not perform.
Second, the regulatory response to black market growth may eventually affect you directly. Proposals for IP-level blocking of offshore gambling sites, payment processing restrictions that prevent UK-issued cards from transacting with unlicensed operators, and enhanced monitoring of VPN usage for gambling purposes are all within the range of policy options that regulators and legislators have discussed. None are currently implemented comprehensively, but the trajectory of enforcement is toward tighter controls rather than looser ones.
Third, the UK problem gambling rate sits at 2.7% under the GSGB’s PGSI methodology (with 3.1% at-risk), or 0.3% under the APMS 2025 clinical-threshold methodology. These rates are measured primarily through surveys of the general population, and they may undercount individuals who gamble exclusively at offshore sites and are less likely to engage with research conducted through licensed operator channels. The actual rate of gambling harm among offshore players may be higher than the headline figures suggest, precisely because this population has self-selected out of the market where harm-reduction tools are mandatory.
The monthly active account count at UKGC-licensed operators fell to 12 million — a 7% decline — while offshore usage grew. That shift represents a migration of revenue, attention and risk from a regulated environment to an unregulated one. For players at Nine Casino, the practical question is not whether the black market exists — you are already in it. The question is whether the trade-offs you accepted to get here are ones you would make again with full information about the responsible gambling gaps that define this space.
Is playing at Nine Casino considered black market gambling?
Nine Casino holds a Curaçao licence and is not an unlicensed operator. However, it is not licensed by the UKGC, which means it operates outside the UK’s regulated market. Industry analyses typically classify Curaçao-licensed platforms serving UK players as part of the offshore or grey market — legally licensed in their home jurisdiction but not authorised to serve the UK market under British gambling law.
Why is the UK offshore gambling market growing so quickly?
The growth from an estimated £5 billion to £16.6 billion between 2019 and 2025 correlates with major regulatory changes in the licensed market including stake limits, affordability checks, self-exclusion requirements and increased operator taxation. Each restriction applied exclusively to the licensed market creates an incentive for some players to move to offshore platforms where those restrictions do not apply.
Can the UK government block access to Nine Casino?
The UKGC coordinates ISP-level website blocks against unlicensed operators, and 1,134 such blocks were implemented in 2025-2026. These blocks can be circumvented using VPNs. More comprehensive blocking measures including payment processing restrictions are within the range of policy options being discussed but are not currently implemented on a scale that would prevent determined access to offshore platforms.
