Short answer: Yes — Polymarket mandates KYC (Know Your Customer) verification across all users from 2024 onwards. UK-based users are permitted to undergo KYC and participate in trading. The United Kingdom does not appear on Polymarket's restricted jurisdiction list (in contrast to the United States). PolyGram delivers an optimised verification pathway for UK traders.
Following Polymarket's rollout of mandatory KYC in 2024, identity confirmation is now compulsory for all new registrations. This resource walks through what Polymarket KYC entails for residents of the UK — which materials you'll supply, what the experience involves, and typical processing timescales.
Does Polymarket Require KYC?
Yes. Polymarket made KYC mandatory for every user during 2024, in response to regulatory demands and its CFTC settlement agreement. Accounts lacking KYC face these constraints:
- Deposits and withdrawals capped at $100
- Restricted access to certain market categories
- Potential account suspension following 30 days without verification
Can UK Residents Pass Polymarket KYC?
Yes — the United Kingdom sits outside Polymarket's list of prohibited nations. Residents of the UK can undergo KYC and trade freely. The restricted jurisdictions (current as of June 2026) comprise primarily:
- United States (all 50 states and overseas territories)
- Iran, North Korea, Cuba, Syria (under international sanctions)
- Additional jurisdictions flagged by FATF guidelines
British nationals, UK permanent residents, and anyone holding a UK address qualify without issue.
What Documents Are Required for Polymarket KYC?
Polymarket engages an external KYC vendor (Persona) to handle identity authentication. The necessary documentation includes:
Tier 1 (up to $2,500 lifetime deposits)
- Government-backed photo identification: UK passport, UK driving licence (full or provisional), or national identity document
- Photo verification: Current photograph or brief video recorded during the verification session
- Duration: Typically 2–5 minutes
Tier 2 (over $2,500 lifetime deposits)
- Complete Tier 1 documentation
- Address verification: Recent UK bank statement (within 3 months), electricity or gas bill, correspondence from HMRC, or local authority tax documentation
- Funds origin statement: For higher-value accounts, Polymarket may ask for clarification regarding the source of your funds (employment contract, company paperwork, etc.)
- Duration: Between 5–15 minutes, plus potential 24-hour period for human assessment
Polymarket KYC Process — Step by Step for UK Users
- Register account: Complete signup using an email address via PolyGram or the main Polymarket platform
- Access verification: Head to Account → Verification (or complete when making your initial deposit)
- Specify location: Choose United Kingdom from the dropdown
- Pick identification type: Select from passport, driving licence, or national ID
- Capture document: Photograph the document using your device's camera within the application
- Facial recognition: Perform a real-time face verification against your ID photograph
- Finalise submission: Send your application and await processing, which typically concludes within 2–5 minutes
Common KYC Rejection Reasons for UK Users
- Poor image quality: Verify documents are clearly visible, properly illuminated, and fully contained within the frame
- Identity discrepancy: Your account email address must correspond precisely with the name on your identification
- Out-of-date credentials: UK passports and driving licences must remain current and valid
- VPN in use: KYC systems validate your IP address location. Turn off any VPN connection before starting verification
- Address documentation too old: Proof of address documents must be dated within the last 3 months — retrieve your most current bank statement
KYC vs Non-KYC Trading: What Limits Apply?
| Verification Level | Deposit Limit | Withdrawal Limit | Market Access |
|---|---|---|---|
| No KYC | $100 lifetime | $100 lifetime | Restricted |
| Tier 1 KYC (ID only) | $2,500 lifetime | Unlimited | Full |
| Tier 2 KYC (ID + address) | Unlimited | Unlimited | Full + VIP |
Does Polymarket KYC Data Get Shared with HMRC?
Polymarket operates as a US-based company and does not routinely transmit UK user information to HMRC. That said:
- UK-authorised trading platforms (Coinbase UK, Kraken) are obligated to report to HMRC under the 2025 digital asset disclosure framework
- Should your funding originate from a reporting platform, HMRC may trace those transfers to your Polymarket holdings
- Under bilateral tax agreements between the UK and US, HMRC may demand Polymarket records during investigations of particular individuals
The upshot: assume your Polymarket transactions are potentially visible to HMRC and maintain proper records for tax purposes.
