Picture a UK product manager at a fintech start-up sitting in front of a spreadsheet of event-contract ideas. Will Reform UK win a particular by-election. Will the Bank of England cut in May. Will Manchester City finish top four. The numbers look enticing. Then someone in the compliance Slack channel asks the awkward question: who regulates this in Britain, and the room goes quiet.
That quiet is the point. The UK has one of the most developed gambling regulatory frameworks in the world, and prediction markets sit awkwardly inside it. Not banned, not blessed, not really named. For anyone trying to build, market, or use these products in the UK, the question of how the Gambling Commission sees them is the first question that has to be answered. Everything else, from payments to advertising to tax, follows from it.
The Commission's starting point is the 2005 Act, not the product label
The Gambling Commission does not care what you call your product. It cares whether the product, as a matter of substance, falls within the Gambling Act 2005. The Act covers gaming, betting, and lotteries, and the definition of "betting" is wide. It captures making or accepting a bet on the outcome of a race, competition, or other event, on the likelihood of anything occurring or not occurring, and on whether anything is or is not true. That last clause does a lot of work.
A contract that pays out one pound if a named candidate wins an election and zero if they do not is, on any sensible reading of those words, a bet on the likelihood of an event occurring. The fact that you settle it on-chain, call it an event contract, or quote it as a price between zero and one does not change the underlying answer. Substance wins.
That is why platforms structured like Polymarket and Kalshi, despite the financial-markets vocabulary, look like betting operators when viewed through the Commission's lens. Our explainer on whether prediction markets are legal in the UK walks through the same logic in more detail.
There is one true exception, and it is statutory rather than a matter of the Commission's judgement. Section 10 of the Gambling Act 2005 provides that a bet is not caught by the Act where the making or accepting of it is a regulated activity within the meaning of section 22 of the Financial Services and Markets Act 2000. In plain terms: if an instrument is authorised and regulated by the Financial Conduct Authority as a financial product, it is not "betting" under the Gambling Act at all, however much it resembles a bet. That is the one mechanism that can defeat the substance test, and it is the only one. So the honest question for anyone building an event-contract product in the UK is not whether it looks financial, but whether it genuinely sits inside FCA regulation. If it does not, substance wins and the Gambling Commission's perimeter applies.
Why no offshore prediction market holds a Commission licence
Here is the awkward fact. The Commission issues remote gambling licences to operators who can demonstrate they meet the licensing objectives: keeping crime out, ensuring fairness, and protecting the vulnerable. Those objectives translate into very specific obligations. Identity verification at sign-up. Source-of-funds checks above thresholds. Self-exclusion via GAMSTOP. Advertising compliant with CAP rules. Anti-money-laundering controls. UK-facing customer support. Annual fees and detailed regulatory returns.
Most offshore prediction-market platforms were not designed for any of that. They were designed for crypto-native users, global liquidity, and minimal friction. The architecture is fundamentally incompatible with what a UK remote betting licence requires. So the platforms do not apply, and the Commission does not invite them.
The result is structural. There is no licensed Polymarket-equivalent serving UK retail customers today, and the platforms that do exist as licensed UK alternatives, like Betfair Exchange and Smarkets, are exchanges built within the licensed perimeter from day one. The Commission itself has said as much. In a February 2026 blog post on prediction markets, it wrote that current products "would fall within the definition of a 'Betting Intermediary' under UK legislation" and that their "core aspects are akin to what in the UK would be described as a 'Betting Exchange'". That is the same category Betfair and Smarkets already sit in. The Commission drew the boundary with the financial regulator in the same post: firms "offering financial services products as opposed to gambling facilities, are authorised and regulated by the Financial Conduct Authority". Our guide to legal alternatives to Polymarket for UK users covers the practical landscape.
What the Commission expects of operators
Reform UK's by-election odds, sure. Premier League title markets, fine. But the operator listing them has to be licensed, and the licence is not a tick-box. It is an active regulatory relationship.
A Commission-licensed betting operator running event contracts needs to satisfy the regulator on the source and adequacy of customer funds protection, the integrity of the market (no insider trading on outcomes the operator controls), the suitability of the events offered (the Commission has historically been twitchy about novelty markets that look distasteful or vulnerable to manipulation), and the advertising of those markets to UK consumers. Affordability checks have become a structural feature of the UK regulatory landscape in recent years, and event-contract platforms are not exempt from the direction of travel.
The upshot for any UK operator considering an event-contract product line: do not assume that wrapping it in financial-markets language gets you out of the Gambling Commission's perimeter. Language is not the test. The boundary between the two regulators is set by section 10 of the Gambling Act, which takes activity regulated under the Financial Services and Markets Act out of the definition of betting. A product falls to the Financial Conduct Authority only if it is genuinely a regulated financial instrument authorised under that Act, not because it is marketed as one. That leaves an operator with two real routes, and only two: hold a Gambling Commission betting licence, or structure the product as an FCA-regulated activity in the way spread betting did. On the evidence so far, only the first route is realistically open. In its February 2026 post the Commission pre-empted the second, saying that "if a prediction market operator was to launch here in Great Britain, we do not believe they would be able to classify themselves as non-gambling products". In other words the regulator has already signalled that it does not expect the FSMA exemption to lift a prediction-market product out of the Gambling Act, however it is packaged. The difference between binary options and event contracts turns on exactly this, and it is a question of regulatory status, not marketing copy.
What the Commission expects of users
The user side is less dramatic. The Commission does not, as a general matter, prosecute individual UK gamblers for using an unlicensed offshore site. The enforcement target is the operator: cease-and-desist letters, payment-blocking arrangements with UK banks and card networks, and pressure on app stores and ad networks to delist non-compliant operators.
But "the Commission does not arrest you" is not the same as "you have no risk". Users on unlicensed sites get none of the consumer protections the licensed regime is built to provide. No dispute resolution through the Independent Betting Adjudication Service. No GAMSTOP self-exclusion enforced on the operator. No clear path to recover funds if the platform halts withdrawals. UK banks and card issuers can and do block deposits to flagged offshore gambling sites, and crypto rails introduce their own AML and tax compliance questions that most retail users underestimate.
For anyone in the UK weighing whether to use Polymarket or a similar offshore venue, the right frame is consumer-protection cost, not legal-risk cost. The honest answer on Polymarket access from the UK lays this out plainly.
How the Commission tends to think about novel products
A conservative regulator, but not a stupid one. The Commission has a long history of dealing with novel betting products: betting exchanges in the early 2000s, in-play markets, novelty politics markets. Its instinct is to extend existing principles rather than write new rule books for every product.
Spread betting is the instructive counter-example, because it went the other way. A spread bet is a betting-shaped product, offered to ordinary retail customers, and yet it sits outside the Gambling Act altogether, regulated by the Financial Conduct Authority rather than the Gambling Commission. That is not an accident of practice; it follows from section 10, which excludes FSMA-regulated activity from the definition of betting. The Commission's own guidance is explicit that spread betting is the FCA's responsibility, not its own. This is the template a prediction-market operator would have to follow to leave the gambling perimeter: not a financial-sounding label, but genuine authorisation as a financial instrument. Nobody offering retail event contracts on elections or football has done that.
For prediction markets, that means the Commission's likely framework, when pressed, looks like this. Is the product a bet within the meaning of the Act? Almost always yes. Is the operator licensed? If no, it should not be marketing to UK consumers. If yes, the standard licensing conditions apply, with additional scrutiny on market integrity for any event where the operator or counterparties might have asymmetric information. The Commission has not, to date, signalled any intention to carve out a separate "event contract" regime that would sit outside the Gambling Act, and there is no obvious political appetite for one.
That regulatory stability is itself useful information. It means the UK route to operating a compliant prediction-market-style product is to do it under a betting licence, on the existing rails, with the existing consumer protections, not to wait for a friendlier regime that does not appear to be coming.
The direction of travel
Which way is the wind blowing? Toward tighter consumer protections, not looser ones. The 2023 White Paper, the affordability framework, the statutory levy on operators, and the ongoing scrutiny of gambling advertising all point in the same direction. A future Commission position on prediction markets is more likely to look like "licensed UK operators may offer these contracts under existing rules with additional integrity safeguards" than like "the Commission steps back and lets the FCA or a new body handle them."
The practical takeaway for operators is to plan for a UK gambling-licensed model if the UK market matters to you. The practical takeaway for users is that the licensed UK exchanges, while narrower in market coverage, are the venues where the consumer-protection regime actually applies.
iPredicta is built for the discovery and analysis side of this market. We surface prediction-market contracts and prices from across the global landscape, including Polymarket and Kalshi, and we write the editorial context that helps UK readers make sense of what those markets are saying, where they sit in UK law, and which licensed venues offer comparable exposure. We do not operate a betting product ourselves. The Commission's perimeter is the operators' problem; our job is to help UK readers navigate it clearly.
Frequently asked questions
Does the UK Gambling Commission regulate Polymarket?
No. The Gambling Commission does not regulate Polymarket, because Polymarket does not hold a UK remote gambling licence and does not, as a matter of policy, serve UK customers. The Commission's jurisdiction is over operators offering gambling to UK consumers. Polymarket geo-blocks UK users and operates from offshore, which puts it outside the licensed perimeter. The Commission's tools against an offshore unlicensed operator are pressure on payment providers, advertising platforms, and app stores rather than direct regulation of the platform. If you encounter a UK-facing advert for an unlicensed prediction market, that is the kind of thing the Commission acts on.
Are prediction markets considered gambling under UK law?
Yes, in almost all cases. The Gambling Act 2005 defines betting broadly to include staking money on the likelihood of an event occurring or on whether something is or is not true, which captures the binary contracts that prediction markets are built around. The financial-markets vocabulary used by platforms like Kalshi does not change the substantive analysis under UK law. There is one statutory exception. Section 10 of the Gambling Act takes out of the definition of betting any bet whose making or accepting is a regulated activity under the Financial Services and Markets Act 2000, which is why spread betting, although betting-shaped and available to retail customers, is regulated by the Financial Conduct Authority rather than the Gambling Commission. The test is FSMA authorisation, not how financial the product sounds. Retail-facing event contracts on political, sporting, or news outcomes that are not FCA-regulated sit squarely within the Gambling Commission's perimeter.
Can a UK company get a Gambling Commission licence to run a prediction market?
Yes, in principle. The Commission's remote betting licence framework can accommodate an event-contract style product, provided the operator meets the standard licensing objectives. That means UK-grade identity verification, anti-money-laundering controls, GAMSTOP integration, affordability assessment, fair-and-open market design, and compliant advertising. The bar is high and the ongoing regulatory relationship is active rather than a one-off approval. Betfair Exchange and Smarkets operate licensed exchange-style products in the UK, so the regulatory pathway clearly exists. What the Commission has not done is create a lighter-touch carve-out specifically for prediction-market products.
What happens to a UK user who uses an unlicensed offshore prediction market?
Generally nothing from the Commission directly. The Commission's enforcement focuses on operators rather than individual UK consumers using offshore sites. But the absence of enforcement risk is not the absence of risk. Users on unlicensed platforms have no recourse to the UK dispute-resolution regime, no GAMSTOP coverage, and no UK consumer protections if the platform halts withdrawals or resolves a market incorrectly. UK banks may block deposits to flagged offshore gambling sites. And winnings still need to be considered for tax purposes; our overview of prediction market tax in the UK and US covers the basics.
Will the UK Gambling Commission's position on prediction markets change soon?
Probably not in the direction operators would want. The regulatory direction of travel in the UK is toward tighter consumer protections, structured affordability checks, advertising restrictions, and a statutory levy on operators. There is no visible political appetite for carving prediction markets out of the Gambling Act or creating a lighter parallel regime. If anything changes, it is more likely to be the Commission setting out clearer expectations for licensed operators offering event contracts than a wholesale rethink of the perimeter. Anyone planning a UK-facing product should build for the gambling-licensed model rather than wait for friendlier rules.
