Polymarket is geoblocked in the UK. UK traders access equivalent CLOB liquidity via PolyGram. 0% fees. Optional KYC. USDC on Polygon.
Step 1: Buy USDC on a UK Exchange
The FCA-registered exchanges that support USDC in the UK: Coinbase UK (best rates, Faster Payments GBP top-up), Kraken UK (low fees, GBP pairs), and Revolut (convenient but check withdrawal limits). Purchase the USDC amount you want to deposit. Add 5-10% extra for gas fees (though Polygon gas is under £0.01 per transaction).
Step 2: Withdraw USDC to Polygon Network
Critical: withdraw USDC on the Polygon network, not Ethereum mainnet. Ethereum mainnet gas fees are £5-30 per transaction; Polygon gas fees are fractions of a penny. On Coinbase: Withdraw → Crypto → USDC → select Polygon as the network → paste your PolyGram deposit address. On Kraken: similar flow, ensure "Polygon (MATIC)" is selected as the network.
Step 3: Find Your PolyGram Deposit Address
Log in to polygram.ink. Navigate to Wallet → Deposit. Your Polygon USDC deposit address is shown as a 0x address and a QR code. Each PolyGram account has a unique HD-derived deposit address. Do not send to the wrong address — cross-chain transfers (e.g., sending to a Polygon address on Ethereum mainnet) result in permanently lost funds.
Minimum Deposit and Confirmation Time
Minimum deposit: $10 USDC. Credits are applied after 12 Polygon block confirmations, typically 90 seconds after your transaction is broadcast. If your USDC does not appear after 10 minutes, check the transaction status on polygonscan.com using your transaction hash. If 12 confirmations are shown there, contact PolyGram support.

Is Polymarket legal in the UK?
Polymarket itself operates in a legal grey area in the UK. Prediction markets settled in cryptocurrency (USDC) are not straightforwardly classified as "gambling" under the Gambling Act 2005, which requires cash prizes to trigger regulation. No UK authority has taken enforcement action against Polymarket. However, Polymarket voluntarily geoblocks UK IP addresses. PolyGram mirrors Polymarket's CLOB liquidity and is accessible to UK users.
Why is Polymarket blocked in the UK?
Polymarket geoblocks UK users as a precautionary compliance measure, not because the UK has explicitly banned it. The Gambling Commission has not issued guidance specifically covering USDC-settled prediction markets. PolyGram was built to give UK traders access to the same Polymarket CLOB order book without the IP restriction.
Do I need a VPN to use Polymarket from the UK?
Using a VPN to circumvent Polymarket's geoblock violates Polymarket's Terms of Service and could result in your account being restricted. A better option is PolyGram, which legally mirrors Polymarket's CLOB liquidity and is fully accessible to UK users without a VPN.
What currency do prediction markets use?
Polymarket and PolyGram use USDC (USD Coin), a US-dollar-pegged stablecoin on the Polygon blockchain. Each contract share is worth between $0.00 and $1.00 USDC, with the final value settling at $1.00 (YES wins) or $0.00 (NO wins). UK users can buy USDC on Coinbase UK, Kraken UK, or any FCA-registered crypto exchange.
Is PolyGram regulated by the FCA?
No. PolyGram is not regulated by the Financial Conduct Authority. Prediction markets are a novel category and no major prediction market platform — including Polymarket or Kalshi — holds FCA authorisation. Always trade only what you can afford to lose.
How do I fund a PolyGram account from the UK?
Purchase USDC on an FCA-registered exchange (Coinbase UK and Kraken UK are the most popular). Send USDC on the Polygon network to your PolyGram deposit address. Deposits are credited after 12 confirmations, typically within 2–3 minutes. Minimum deposit is $10 USDC.
