Short answer: Yes — Polymarket mandates KYC (Know Your Customer) verification across all user accounts from 2024 onwards. UK-based residents are permitted to undergo KYC and participate in trading. The UK does not appear on Polymarket's restricted country roster (in contrast to the USA). PolyGram provides an optimised UK KYC pathway.
Following Polymarket's expansion of KYC protocols in 2024, all new account holders must complete identity verification. This resource walks UK users through what Polymarket KYC entails — documentation needed, the verification workflow, and typical processing timescales.
Does Polymarket Require KYC?
Absolutely. Polymarket rolled out compulsory KYC across its entire user base in 2024, in response to regulatory scrutiny and a CFTC agreement. Accounts lacking KYC face these constraints:
- Deposits and withdrawals cannot exceed $100
- Access to certain market segments remains unavailable
- Accounts may face suspension after 30 days without verification
Can UK Residents Pass Polymarket KYC?
Absolutely — the United Kingdom sits outside Polymarket's list of prohibited nations. Residents of the UK may complete KYC and trade freely. The prohibited jurisdictions (as of June 2026) include primarily:
- United States (all 50 states + territories)
- Iran, North Korea, Cuba, Syria (sanctions-related)
- Additional FATF-designated regions
British nationals, UK permanent residents, and those with a UK domicile qualify fully.
What Documents Are Required for Polymarket KYC?
Polymarket engages an external KYC provider (Persona) to handle identity checks. The following documents are needed:
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: Photograph or brief video clip captured during the verification session
- Time required: 2–5 minutes
Tier 2 (over $2,500 lifetime deposits)
- Complete Tier 1 documentation
- Proof of address: UK bank statement (preceding 3 months), utility invoice, HMRC correspondence, or local authority tax notice
- Source of funds: For higher deposit amounts, Polymarket may ask for documentation confirming the origin of funds (employment contract, business licence, etc.)
- Time required: 5–15 minutes plus up to 24 hours for human verification
Polymarket KYC Process — Step by Step for UK Users
- Create account: Register via email through PolyGram or the main Polymarket site
- Go to settings: Select Account → Verification (alternatively, a prompt appears when attempting to deposit)
- Select country: Choose United Kingdom
- Document type: Pick from passport, driving licence, or national ID
- Upload or scan: Photograph the document using your device's camera within the application
- Selfie check: Complete a live facial verification against your ID photograph
- Submit and wait: Instant approval usually occurs within 2–5 minutes
Common KYC Rejection Reasons for UK Users
- Blurry photos: Confirm the document is clearly visible, properly illuminated, and fully captured
- Name mismatch: Your registered email address must correspond precisely with your identification document
- Expired documents: UK passports and driving licences must remain current
- VPN active: KYC systems verify your IP address location. Deactivate VPN before submitting verification
- Proof of address older than 3 months: Financial institutions release statements monthly — submit your latest 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-domiciled company and does not routinely transmit UK user information to HMRC. That said:
- UK-authorised platforms (Coinbase UK, Kraken) are required to submit data to HMRC under 2025 cryptoasset disclosure obligations
- If your initial funding originated from a reporting exchange, HMRC may trace those transfers into Polymarket
- HMRC may seek Polymarket records under bilateral UK-US tax cooperation frameworks when conducting a particular investigation
The upshot: assume your Polymarket transactions are potentially visible to HMRC and maintain appropriate records.
FAQ — Polymarket KYC UK
- How long does Polymarket KYC take for UK users?
- Tier 1 KYC verification through automated systems generally concludes in 2–5 minutes. Should manual assessment be required, the process may extend to 24 hours. PolyGram's registration pathway typically finalises most UK verifications in around 5 minutes.
- Can I use Polymarket without KYC in the UK?
- You may set up an account and trade with a maximum of $100 in cumulative deposits without completing KYC. Verification becomes compulsory once you exceed this threshold. The majority of UK traders opt to complete KYC at the outset to prevent accidentally surpassing the cap.
- What happens if Polymarket rejects my KYC?
- KYC denials are typically resolvable — enhance image clarity, select an alternative form of ID, or turn off VPN. Should the issue persist, reach out to Polymarket's support team via help.polymarket.com.
