Polymarket is accessible in Sierra Leone — the platform does not geoblock Sierra Leonean IP addresses. This West African nation uses mobile money extensively, providing workable on-ramps to crypto. Here’s what users need to know about using Polymarket.
Current Status: Accessible
Sierra Leone is not on Polymarket’s geoblocked countries list. The platform is accessible from local IP addresses. Users can sign up, deposit, and trade on all available markets.
The country uses the Sierra Leonean leone (recently redenominated as the new leone, SLE). Mobile money — Orange Money and Afrimoney — is widely used and provides a practical route into crypto through peer-to-peer trading.
The legal landscape for prediction markets sits in a grey area: there is no specific law on crypto or prediction markets, and no record of enforcement against users.
The Legal Landscape
Bank of Sierra Leone (BSL)
The Bank of Sierra Leone (BSL) is the central bank and has explored digital-finance initiatives, including a digital-leone pilot. It has not established a comprehensive framework for consumer cryptocurrency activity or decentralized prediction markets.
Gambling and Prediction Markets
Sierra Leone does not have a specific legal framework that addresses online prediction markets. Prediction markets operate in an undefined gap. There is no explicit ban and no enforcement targeting users, but the activity is legally undefined.
How to Deposit from Sierra Leone
Mobile money provides a practical on-ramp to crypto.
Step 1: Buy USDC on a Global Exchange
| Exchange | SLE Support | Mobile Money | P2P | Notes |
|---|---|---|---|---|
| Binance | Yes (P2P) | Yes | Yes | Global leader; P2P on-ramp |
| Bybit | Partial (P2P) | Partial | Yes | Card or P2P purchase |
| OKX | No | No | Yes | Low fees; P2P available |
| KuCoin | No | No | Yes | Widely used globally |
Deposit Methods Explained
Mobile Money and P2P: Load a mobile-money wallet, then use peer-to-peer trading on an exchange to buy USDC or USDT. This is the most practical route given limited banking.

- Go to Deposit on Polymarket
- Select Use Crypto and copy your deposit address
- Send USDC from your exchange to the Polymarket address
- Choose Polygon for the lowest fees ($3 minimum, arrives in seconds)

Tax Implications
Sierra Leone’s treatment of crypto is fact-dependent and not explicitly defined.
Income Tax
Sierra Leone levies income tax on residents under the National Revenue Authority (NRA). There is no dedicated crypto tax, and the classification of crypto gains is not clearly defined, so treatment can be uncertain.
What to Consider
- Keep dated records of all deposits, trades, withdrawals, and SLE/USD conversion rates.
- Because the crypto treatment is not explicitly defined, consult a tax adviser if you trade at scale.
