Key takeaway: Polymarket requires identity verification (KYC) for UK users, but several legitimate alternatives exist with varying verification requirements, fee structures, and market selection. This guide compares the main options available to British traders in 2026.
Why Polymarket's KYC Requirements Matter for UK Users
Polymarket, the largest prediction market platform globally, implemented Know Your Customer (KYC) requirements for UK-based users following regulatory clarification from the Financial Conduct Authority (FCA). This shift fundamentally changed how British traders access the platform. Before 2026, many UK users operated in a grey area; today, the requirement is explicit and enforced.
KYC verification typically involves submitting government-issued identification, proof of address, and sometimes additional documentation. For Polymarket specifically, UK users must complete identity verification before depositing funds or trading. The process usually takes 24–48 hours, though delays can occur during high-volume periods.
Understanding why this matters is crucial: KYC compliance protects platforms from money laundering and fraud, but it also creates friction for users who value privacy or prefer faster onboarding. This reality has driven demand for alternatives—both regulated platforms that accept UK traders and decentralised options with lower barriers to entry.
Polymarket's KYC Process: What UK Users Face
Polymarket's verification process for UK residents follows a tiered approach. At minimum, you'll need:
- A valid UK passport, driving licence, or national ID card
- Proof of address (utility bill, bank statement, or council tax letter dated within the last three months)
- Basic personal information (full name, date of birth, residential address)
The platform uses third-party verification services to confirm identity. Once submitted, your application enters a queue for manual review. Polymarket's support team has been transparent that verification can take longer during peak trading periods, particularly around major events or elections.
One often-overlooked detail: Polymarket requires you to verify the payment method used for deposits. If you fund your account via bank transfer, the account holder's name must match your verified identity on Polymarket. This prevents account sharing and layering.
For UK users, this process is standard across most regulated platforms. However, the inconvenience has motivated traders to explore alternatives—particularly those offering faster onboarding or lower verification thresholds for smaller trades.
Regulated UK Alternatives with Lower KYC Friction
Betfair Exchange (Prediction Markets Section)
Betfair, the UK's largest betting exchange, launched a formal prediction markets section in 2025 and expanded it significantly by 2026. For UK residents, Betfair offers a substantial advantage: you likely already have an account if you've bet on sports. If not, Betfair's KYC process is streamlined because the company operates under the Gambling Commission's remit.
Betfair's identity verification is often faster than Polymarket's because it integrates with UK banking systems and credit reference agencies. Many users complete verification in under 24 hours. The platform offers markets on political elections, economic indicators, and major events—though the selection is narrower than Polymarket's.
Trade-off: Betfair's prediction markets carry gambling tax implications for UK residents (typically 15% on net winnings), whereas Polymarket operates in a regulatory grey zone that may change. Betfair is explicitly regulated, which provides legal certainty but higher costs.
Smarkets
Smarkets is a UK-regulated prediction exchange founded in 2010. It operates under Gambling Commission oversight and accepts UK residents directly. The KYC process mirrors Betfair's—streamlined for UK users—and typically completes within 24 hours.
Smarkets offers markets on elections, sports, entertainment, and economics. The platform is smaller than Polymarket, meaning lower liquidity on niche markets, but it excels on major events where multiple traders compete. The user interface is clean and mobile-friendly.
Notably, Smarkets charges a 2% commission on net winnings, lower than some competitors. For UK traders, the regulatory clarity is valuable: you're not navigating potential future FCA enforcement actions.
PredictIt (US-Based, Available to Some UK Users)
PredictIt, operated by Victoria University of Wellington in New Zealand with a US focus, technically restricts accounts to US residents. However, some UK users have historically accessed it via VPN or through family members' accounts. This approach carries legal and practical risks and is not recommended.
PredictIt's advantage—minimal KYC for US users—doesn't extend to UK traders, making it less relevant for this comparison.
Decentralised and Blockchain-Based Alternatives
Omen (Gnosis Protocol)
Omen is a decentralised prediction market platform built on the Ethereum blockchain. It requires no KYC in the traditional sense—you connect a cryptocurrency wallet (MetaMask, Ledger, etc.) and begin trading immediately.
For UK users uncomfortable with Polymarket's identity requirements, Omen offers genuine privacy. However, this comes with trade-offs: the platform is less user-friendly, liquidity is significantly lower, and you must manage your own crypto wallet security. Markets are smaller and less frequently updated than Polymarket's.
Regulatory risk exists: the FCA has not formally blessed decentralised prediction markets, and using them may expose you to future enforcement action if regulations tighten. Additionally, if you convert crypto profits back to GBP, HMRC may request records of your trading activity—KYC avoidance doesn't eliminate tax obligations.
Augur v2
Augur is another decentralised protocol where users create and trade on prediction markets without intermediaries. Like Omen, it requires only a crypto wallet and offers complete pseudonymity.
The platform is technically sophisticated but has struggled with liquidity and user adoption. For most UK traders, Augur's complexity outweighs its privacy benefits. Markets often remain illiquid, making it difficult to exit positions at fair prices.
Comparison Table: KYC, Fees, and Market Selection
Here's a structured comparison of the main options available to UK users in 2026:
| Platform | KYC Required | Typical Verification Time | Commission/Fees | Market Breadth |
|---|---|---|---|---|
| Polymarket | Yes (mandatory for UK) | 24–72 hours | 2% on winnings | Extensive (1000+ active markets) |
| Betfair Prediction Markets | Yes (streamlined for UK) | 12–24 hours | 2% + 15% gambling tax | Moderate (100–300 markets) |
| Smarkets | Yes (streamlined for UK) | 12–24 hours | 2% + gambling tax | Moderate (50–200 markets) |
| Omen (Decentralised) | No (wallet only) | Immediate | Variable (protocol-dependent) | Limited (50–100 markets) |
| Augur v2 | No (wallet only) | Immediate | Variable | Limited (20–50 markets) |
Hidden Costs and Regulatory Considerations
When comparing Polymarket KYC alternatives, don't overlook hidden costs. Regulated UK platforms (Betfair, Smarkets) charge gambling tax on net winnings—effectively a 15% levy on profit. If you trade £10,000 and profit £2,000, you owe £300 in tax. Polymarket doesn't currently enforce this, but future regulatory changes could alter the landscape.
Decentralised platforms avoid gambling tax because they operate outside the regulatory framework. However, HMRC still expects you to report crypto trading gains as capital gains tax (20% for higher earners). The burden shifts from the platform to you—and tax authorities increasingly scrutinise crypto transactions.
Another consideration: account security. Regulated platforms (Betfair, Smarkets, Polymarket) offer account protection and dispute resolution. If your account is hacked, you have recourse. Decentralised platforms offer no such protection—if your wallet is compromised, your funds are permanently lost.
For UK users, the regulatory environment remains uncertain. The FCA has not formally licensed prediction markets as a distinct asset class. Polymarket operates in a grey zone; if the FCA tightens rules, UK access could be restricted. Regulated platforms like Betfair and Smarkets face less regulatory risk because they already operate under Gambling Commission oversight.
Risk disclaimer: Prediction markets are speculative and carry real financial risk. You can lose your entire stake. Regulatory status in the UK remains fluid—platforms may restrict access, change terms, or face enforcement action. Never invest more than you can afford to lose, and always verify a platform's regulatory status before depositing funds. This article is educational; it does not constitute financial advice.
Which Alternative Is Right for You?
Your choice depends on your priorities:
- Maximum market selection and liquidity: Accept Polymarket's KYC and benefit from the largest prediction market ecosystem globally. The verification process, while inconvenient, is standard and usually completes within 48 hours.
- Fastest UK onboarding: Choose Betfair or Smarkets. Both streamline verification for UK residents and offer legal certainty. Accept that you'll pay gambling tax on profits.
- Privacy and immediate access: Use Omen or Augur. Understand that you're trading in a less liquid, less user-friendly environment and accepting regulatory uncertainty. Ensure you report gains to HMRC.
- Balanced approach: Use Betfair or Smarkets for major events (elections, sports) where liquidity is high, and Polymarket for niche markets where its larger user base creates better odds.
Frequently Asked Questions
Do I have to use Polymarket if I'm in the UK?
No. Several regulated alternatives exist (Betfair, Smarkets) and decentralised options (Omen, Augur) are available. However, Polymarket offers the broadest market selection, so many traders find it worth the KYC friction.
Can I use a VPN to bypass Polymarket's KYC?
Technically, a VPN might mask your location, but Polymarket verifies identity through government documents—your passport or driving licence will reveal your UK residency. Attempting to circumvent KYC violates Polymarket's terms and could result in account suspension and fund forfeiture.
How long does Polymarket's KYC actually take?
Officially, 24–48 hours. In practice, 2–3 days is common. During major events (elections, significant economic announcements), delays can stretch to a week. Plan ahead if you want to trade a specific event.
Are Betfair and Smarkets prediction markets as good as Polymarket?
They're good for major events but smaller overall. Polymarket has more niche markets and generally higher liquidity. Betfair and Smarkets excel on UK-focused events and elections.
Is trading on decentralised platforms legal in the UK?
Legally, it's murky. The FCA hasn't explicitly banned decentralised prediction markets, but it hasn't endorsed them either. You're operating in regulatory grey space. If you use them, ensure you report gains to HMRC—that's non-negotiable.
Do I have to pay tax on prediction market profits?
Yes. On regulated platforms (Betfair, Smarkets), tax is deducted automatically (15% gambling tax). On Polymarket and decentralised platforms, you're responsible for reporting gains to HMRC. Failure to do so is tax evasion. For most traders, capital gains tax (20%) or income tax (20–45%) applies, depending on your circumstances.
Can I withdraw funds quickly from these platforms?
Regulated platforms (Betfair, Smarkets, Polymarket) typically process withdrawals within 5–10 business days. Decentralised platforms are instant (once you transfer crypto to your wallet) but require you to manage the conversion back to GBP yourself, which can take 1–2 days via an exchange.
Final Thoughts on Polymarket KYC and Alternatives
Polymarket's KYC requirement for UK users is here to stay. Rather than viewing it as an obstacle, consider it a sign that the prediction market industry is maturing and moving toward mainstream adoption. The inconvenience of identity verification is a small price for accessing a platform with thousands of active markets and deep liquidity.
That said, alternatives exist
