Short answer: Yes — Polymarket mandates KYC (Know Your Customer) verification for all users from 2024 onwards. UK residents are able to complete KYC and participate in trading. The UK does not appear on the restricted country list (in contrast to the USA). PolyGram provides an optimised UK KYC process.
Following Polymarket's expansion of KYC requirements during 2024, identity verification is now compulsory for every new account. This article outlines precisely what Polymarket KYC entails for users in the UK — which documents you'll need, what the process involves, and typical timeframes.
Does Polymarket Require KYC?
Absolutely. Polymarket rolled out universal mandatory KYC in 2024, in response to regulatory scrutiny and its CFTC settlement agreement. Without completing KYC:
- Deposits and withdrawals remain capped at $100
- Access to certain market categories is unavailable
- After 30 days of unverified usage, your account faces potential suspension
Can UK Residents Pass Polymarket KYC?
Absolutely — the United Kingdom is not included on Polymarket's restricted country list. Residents of the UK may complete KYC and trade freely. The restricted countries (as of June 2026) comprise primarily:
- United States (all 50 states + territories)
- Iran, North Korea, Cuba, Syria (sanctions-related)
- Additional FATF-designated jurisdictions
British nationals, permanent residents, and those holding a UK address qualify entirely.
What Documents Are Required for Polymarket KYC?
Polymarket engages a third-party verification provider (Persona) to handle identity checks. The necessary documents include:
Tier 1 (up to $2,500 lifetime deposits)
- Government-issued photo ID: UK passport, UK driving licence (full or provisional), or national identity card
- Selfie: Current photograph or brief video recorded during the verification session
- Time required: 2–5 minutes
Tier 2 (over $2,500 lifetime deposits)
- All Tier 1 documents
- Proof of address: Recent UK bank statement (within 3 months), utility bill, HMRC correspondence, or council tax notice
- Source of funds: For substantial amounts, Polymarket may request clarification regarding funds origin (employment letter, business documentation, etc.)
- Time required: 5–15 minutes plus potentially 24 hours for human verification
Polymarket KYC Process — Step by Step for UK Users
- Create account: Register using your email via PolyGram or Polymarket's main site
- Go to settings: Select Account → Verification (alternatively, a prompt appears when attempting to deposit)
- Select country: Choose United Kingdom
- Document type: Select passport, driving licence, or national ID
- Upload or scan: Photograph the document using your device's camera within the app
- Selfie check: Complete a live facial recognition check matching the document
- Submit and wait: System approval ordinarily occurs within 2–5 minutes
Common KYC Rejection Reasons for UK Users
- Blurry photos: Make sure the document is clearly visible with adequate lighting and fully captured
- Name mismatch: Your account email name must correspond precisely to your ID
- Expired documents: UK passports and driving licences must remain current
- VPN active: Verification systems monitor IP addresses. Deactivate VPN prior to verification
- Proof of address older than 3 months: Financial institutions release statements regularly — obtain the most current version
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. Nevertheless:
- UK-regulated platforms (Coinbase UK, Kraken) are required to report to HMRC under the 2025 cryptoasset disclosure framework
- Should your deposits originate from a reporting platform, HMRC may track those funds through to Polymarket
- HMRC may demand data from Polymarket under bilateral UK-US tax agreements when investigating a particular user
The realistic outcome: assume HMRC can observe your Polymarket transactions and declare them appropriately.
