Cosmobet

Platform and background

Cosmobet is an offshore online casino and sportsbook that launched in 2023 as one of the newer brands in the Santeda International stable. It runs a crypto-friendly model, accepting both traditional and cryptocurrency deposits, and offers real-money slots, live dealer tables, virtual sports and esports markets. The brand markets itself heavily through affiliate channels, and a cluster of look-alike 'official UK' mirror domains and review pages promote it to British searchers, several of them using 'not on GamStop' framing. None of this changes the underlying position: Cosmobet is an offshore Curacao brand, not a UK-regulated operator, and the consumer protections that come with a UK Gambling Commission licence do not apply to players who use it.

Ownership and the Santeda group

Cosmobet is operated by Santeda International B.V., a company registered in Curacao (company registration 151296), with Santeda International Limited, a Cyprus-registered entity, acting as its EU and EEA representative. The same group sits behind a family of sister brands, most prominently Mystake, alongside Goldenbet, Velobet and Rolletto, with newer names such as Donbet and LocasBet also linked to the network. This group structure matters for anyone trying to recover money, because reporting and complaints suggest the operator moves players between sister sites, and industry coverage indicates the underlying Curacao licensing entities have been reorganised, with several Santeda brands reported to have shifted to a company called GTW B.V. as scrutiny has grown. Identifying the correct legal entity is therefore an important first step in any complaint.

Licence and UK position

Cosmobet operates under a Curacao licence rather than any UK Gambling Commission authorisation, so it is not UKGC-regulated and is not covered by GamStop, the British national self-exclusion scheme. Operator terms and review listings cite a Curacao Gaming Control Board licence numbered OGL/2024/1798/1048 issued to Santeda International B.V., though the wider Santeda network has been reorganising its Curacao licence entities, so Clinton & Co treats this number as current but subject to change and recommends confirming the live entity before acting. On UK access the picture is mixed. Reputable review listings such as AskGamblers show the brand as restricted in the United Kingdom, yet UK players continue to report that they can register and deposit, and the GAMRS report describes active UK-facing promotion. In practice this is a brand whose terms point away from the UK while UK players still report access, and either way the UKGC's protections do not apply.

The GAMRS report and what UK players can do

In December 2025 GAMRS, the Gambling Industry Accreditation, Monitoring & Registration Service, published a report co-authored with DealMeOut that names Cosmobet as one of five Santeda International brands forming a UK-facing offshore network said to generate over GBP 2 billion, roughly USD 2.7 billion, a year. The report alleges the network leans on 'not on GamStop' affiliate marketing aimed at self-excluded gamblers, deploys aggressive retention tactics and migrates users between sister sites after they try to stop. A survey of UK respondents reported combined losses of about USD 322,500 on the flagship brand, Mystake, alone. If you are a UK player who lost money to Cosmobet, particularly where a self-exclusion request was ignored or where no affordability or KYC checks were applied before losses mounted, the route is to raise a formal complaint through the operator's own process and, where appropriate, to escalate with the support of regulated legal partners. Keep your account history, deposit records and any self-exclusion or support correspondence, as this evidence is central to building a case.

If you are in the United States

There is no state regulator standing behind Cosmobet for a United States player: online gambling is licensed state by state and an offshore site like Cosmobet holds no state licence, so nothing in state law reaches your Cosmobet balance. In August 2025 a coalition of 50 state attorneys general asked the Department of Justice to block offshore platforms and their payment systems under the Unlawful Internet Gambling Enforcement Act, which is enforcement rather than a route to the money Cosmobet holds. Your state consumer protection office or attorney general can log the Cosmobet dispute. The route that reaches Cosmobet itself is the one attached to the Cosmobet licence: the Curaçao route above.

If you are in the EU

The EU is not one answer on Cosmobet. Austria: the Supreme Court (1 Ob 229/20p) treats contracts with a provider that has no Austrian concession as ineffective, with the stake repayable, which is the route an Austrian Cosmobet player takes. Germany: the Court of Justice of the EU, Case C-440/23 (16 April 2026), confirmed that a consumer may claim restitution of stakes lost with an operator like Cosmobet on games prohibited in Germany, on facts involving Malta-licensed operators rather than Cosmobet; the Federal Court of Justice has designated I ZR 216/25 as its lead decision and the ruling is pending after a hearing on 17 September 2026, so a German Cosmobet claim is not yet settled law. Netherlands: the Hoge Raad decided on 3 July 2026 that operating without a Dutch licence does not make the Cosmobet gambling contract void, so a Dutch Cosmobet player gets no automatic refund, only claims against Cosmobet for mistake or in tort on their own facts. Nowhere else in the EU have we found a sourced domestic route against Cosmobet; against Cosmobet it is the Curaçao route above that applies.

If you are in Canada or Australia

In Canada the only regulator with a player-dispute process is Ontario’s, and it reaches Ontario-registered sites only, so it does not reach Cosmobet: the AGCO says it cannot get your money back from Cosmobet and only assists with disputes about regulated sites, and iGaming Ontario has no legal relationship with unregulated operators and cannot refund wagers. Every other province runs a government monopoly, and we have found no domestic route against Cosmobet there. In Australia the Interactive Gambling Act 2001 bans online casinos outright; ACMA accepts complaints about breaches but says plainly that Australian regulators cannot help if an overseas site such as Cosmobet withholds your winnings, and points Cosmobet players back to the licensing authority abroad. For Cosmobet that means the Curaçao route above.

If you are in the UK

A UK player has no domestic adjudicator for a Cosmobet dispute. The Gambling Commission says it is illegal to provide gambling to consumers in Great Britain without the operating licence Cosmobet does not hold, wherever in the world the gambling is provided from, and Cosmobet holds no such licence. So GAMSTOP, which covers only GB-licensed operators, never applied to Cosmobet; the ADR requirement in the licence conditions, and IBAS, which adjudicates only against operators registered with it, do not reach Cosmobet; and the Commission has no powers to resolve individual complaints or help consumers get money back from Cosmobet, although it asks for unlicensed sites to be reported to intelligencereports@gamblingcommission.gov.uk. What reaches Cosmobet is the Curaçao route above, the one attached to the Cosmobet licence.
